1. Introduction

1.1 Information in this notice

This notice has been updated as a result of the UK leaving the EU. It gives details of the various biofuels and their excise duty rates. It also explains the roles and responsibilities of producers (and in some cases, users) of these products.

1.2 Who should read this notice

You should read this notice if you:

• manufacture biofuels as fuel for any engine, motor or other machinery

• blend biodiesel or bioethanol with other oils

• manufacture other fuel substitutes and fuel additives

• use biofuels in the production of electricity

Changes to excise duty rates are normally contained in the annual Finance Act and are published in Tax Information and Impact Notes. The VAT law is the Value Added Tax Act 1994 and orders and regulations made under that Act.

This notice explains how we interpret the law and is not a substitute for the law. However, parts of this notice have the force of law. These are identified at the relevant places in the notice. Where appropriate we will quote the law and we will use the titles and abbreviations used above.

1.4 Health and safety

You must comply with all the legal provisions relating to health and safety such as the Health and Safety at Work Act 1974. These provisions may include the need to display warning notices, and to issue health and safety instructions, to both staff and visitors.

If you issue special equipment or protective clothing to your staff when they’re undertaking activities such as handling, inspecting or sampling biodiesel then you must provide similar clothing and equipment to us when we undertake the same activities.

1.5 Health and Safety Executive (HSE) – domestic production of biodiesel

The HSE has published advice on the hazards of producing biodiesel at home. The main points are as follows:

Biodiesel is produced commercially and can be bought from some petrol stations. However there are ‘recipes’ available on the internet for the domestic production of biodiesel. These usually involve mixing methanol with sodium hydroxide (also known as caustic soda or lye), and pouring the resulting mixture into vegetable oil.

Such home production raises serious health and safety concerns, as it involves hazardous chemicals and the risk of fire and explosion.

Making biodiesel is a potentially hazardous process that should only be carried out in controlled conditions by people with the proper training and experience.

At the very least a poorly made product could seriously damage a vehicle engine.

Get more information from the HSE website or by phoning the HSE Info Line on Telephone: 0845 345 0055.

1.6 Renewable Transport Fuel Obligation administered by the Department for Transport

Support is available for UK biofuels through the Renewable Transport Fuel Obligation (RTFO). Fossil fuel suppliers have an obligation to supply a certain percentage of their fuel as biofuel. They demonstrate this by either redeeming Renewable Transport Fuel Certificates (RTFCs) or paying a buy out price. You can find the buy-out price in the RTFO.

Suppliers of biofuels in the UK can apply to the Department for Transport (DfT) to receive one RTFC for every litre of liquid biofuel or kilogram of biogas they supply. These certificates can be:

• traded (providing a potential revenue stream to biofuel suppliers)

• used by fossil fuel suppliers to meet their obligation

The DfT also requires reports on the carbon and sustainability of biofuel supplied.

More information is available on the DfT website.

Find out more about biofuel regulation and the RTFO.

2. Biofuel producers’ obligations

2.1 What biodiesel, bioblend, bioethanol and bioethanol blend are

Biodiesel is described in the law as a diesel quality liquid fuel that is produced from biomass or waste cooking oil, where the:

• ester content is not less than 96.5% by weight

• sulphur content does not exceed 0.005% by weight, or is nil

Diesel quality means that the fuel is a substitute for diesel rather than petrol.

‘Bioblend’ means any mixture that is produced by mixing both:

• biodiesel

• heavy oil that has not been charged with the excise duty on hydrocarbon oil

‘Bioethanol’ means a liquid fuel:

• consisting of ethanol produced from biomass

• capable of being used for the same purposes as light oil

‘Bioethanol blend’ means any mixture that is produced by mixing both:

• bioethanol

• hydrocarbon oil not charged with excise duty

2.2 Other fuel substitutes

Any liquid that is not hydrocarbon oil, biodiesel, bioblend, bioethanol or bioethanol blend but is used in place of mineral oil to fuel any engine, motor or other machinery is classed as a fuel substitute. Read paragraph 3.1.1 for more details. This includes either any liquid:

• used as a fuel in place of mineral oil

• which is used as an additive or extender to a mineral oil

• which is used as an additive or extender in a fuel substitute

However, water is not considered to be a fuel substitute when used in a diesel emulsion when the emulsion is stabilised with additives. Duty is charged only on the non-water part of the fuel.

2.3 Fuel additives

Products such as fuel system cleaners, injector cleaners, fuel conditioners and biocides are considered to be fuel additives and are liable to excise duty. Any product that is added into the fuel supply of vehicles either by the filler cap or by various parts of the fuel system, for example the carburettor, is treated as a fuel additive.

The duty rate is determined by what sort of engine the product is designed to be used in. Products designed for:

• use in a diesel engine attract the heavy oil rate

• an unleaded petrol engine attract the unleaded petrol rate

Products designed for use in leaded petrol engines attract the leaded petrol rate.

Products designed to be multi-purpose (that is, for use in any kind of engine) attract the unleaded petrol rate.

Any product that is 100% hydrocarbon oil and is used solely for lubrication is exempt from duty.

2.4 Your obligations

You’ll need to register and account for the duty due on any products set aside or delivered for use as motor fuel if you:

• produce 2,500 litres or more of biofuels a year

• use 2,500 litres or more of biofuels as motor fuel on which duty has not been paid

You’ll need to do the following:

Step	Action
1.	Register for duty on biofuels and other fuel substitutes using the online service
2.	Use form EX103 or EX103A to provide information (‘make entry’) about your site or premises
3.	Keep records relating to the production and trade in biofuels
4.	Issue detailed delivery notes for each supply of biofuels
5.	Complete and send returns to HMRC showing the excise duty due for the return period (for example, 1 June to 30 June)
6.	Pay the excise duty due (see paragraph 4.4)

If you have produced less than 2,500 litres in the last 12 months, or if you expect to produce less than this amount in the next 12 months, you may be an exempt producer. If you’re an exempt producer you only need to keep production records (see item 3 in the above table). Read paragraph 4.2.1 for more information.

2.5 How to register

Register using the online service within 30 days of producing or using 2,500 litres or more of any biofuel or other fuel substitute.

After you register we’ll send you a registration number. You’ll need to use this in all returns and correspondence about your production or use of any biofuel or other fuel substitute.

If you already have a deferment agreement in place (for example, if you’ve previously completed form HO10) you must tell HMRC about the agreement. This will prevent central assessments being raised on your record.

To tell HMRC, email: morcexciseeast@hmrc.gov.uk.

2.5.1 Tell HMRC (‘make entry’) about your site or premises

To complete your registration you must also provide information about each of your sites or premises to HMRC using form:

• EX103, if you’re a sole trader, unincorporated partnership or other unincorporated body

• EX103A, if you’re a limited company or a limited liability partnership (LLP)

You can also contact the Excise helpline for copies of the forms.

Completed forms should be sent to the Mineral Oils Relief Centre (MORC).

Following receipt of your application, you may be visited to examine the suitability of your premises.

2.6 Producing biofuels or fuel substitutes, or both, on your registered (entered) premises

You only need to enter your premises once for all your production of biofuels or fuel substitutes. However, if you change premises, add more premises or change the type of fuel that you produce, you must tell us at the address in paragraph 2.5 above.

2.7 Other obligations

The transport, storage, use and the treatment processes associated with producing biodiesel from tallow (melted and clarified animal fat) and waste vegetable oil (and in some circumstances from virgin non-waste vegetable oils) can be subject to various controls regulated by the Environment Agency. These controls may include a requirement for a Pollution Prevention and Control (PPC) Permit or a Waste Management Licence (WML).

Generally, the production of biodiesel by individuals such as householders and farmers for their own use, that is, for non-commercial purposes, would not be subject to the PPC Regulations. Where a PPC permit is not needed and where biodiesel production involves the treatment of waste the requirement for waste management controls will still be relevant.

The Environment Agency considers that waste derived biodiesel has not ceased to be waste until it has been burnt in an engine for energy recovery. The Environment Agency has set out a position that it does not consider that requiring environmental authorisations for the storage, supply and use of waste derived biodiesel for use as a motor fuel is in the public interest.

The use of waste derived biodiesel to support combustion in industrial plant such as a boiler will be subject to controls under the Waste Incineration Directive and regulated through PPC by local authorities or the environment agency.

Failure to secure the appropriate authorisation from the agency may lead to enforcement action. Further details on which controls apply can be obtained by contacting your local Environment Agency office on telephone: 08708 506 506.

3. Biodiesel, bioethanol and their blends

3.1 Rates of duty that apply to biofuels

Changes to excise duty rates are normally contained in the annual Finance Act and are published in Tax Information and Impact Notes available from the GOV.UK website. Current and previous rates are also available from the GOV.UK website.

3.1.1 Duty rates for fuel substitutes

Under the Hydrocarbon Oil Duties Act 1979 (HODA), the rate of duty on additives and extenders is that of the host oil. The host oil means whatever oil they are added to. Where additives or extenders are added to rebated fuel or liquefied petroleum gas (LPG), the rate of duty on the additives or extenders should be that of the rebated fuel or LPG. We have amended UK legislation to meet our obligation under the EPD.

With fuel substitutes, the duty rate is applied to the whole non-hydrocarbon oil content of the liquid. So, if a duty paid fuel substitute is added to another fuel substitute which is not duty paid, duty is due under Section 6A of HODA on the duty unpaid part of the mixture.

3.2 What biomass is

Biomass is described in HODA as meaning the biodegradable fraction of:

• products, wastes and residues from agriculture, forestry and related activities

• industrial and municipal waste

This does not include mineral oils.

3.3 Using straight vegetable oil (SVO) or used cooking oil (UCO) to produce biodiesel

If we suspect, either through lack of supporting evidence, or due to other information, that your product does not meet the biodiesel specification, we may take representative samples for testing (see regulations 10 and 11 of Biofuels and Other Fuel Substitutes (for example, Payment of Excise Duties, etc) Regulations 2004). Producers should provide evidence by having their fuel regularly tested against all aspects of the specification. Read paragraph 2.1 for more information.

The following paragraph has the force of law.

Under the powers given by Regulation 6 of the Revenue Traders (Accounts and Records) Regulations 1992 HMRC requires that details of recipes used to produce biodiesel are kept and preserved for 6 years. This requirement also applies to supporting documents showing that the recipe is followed for each batch produced and to the preservation of any test results linked to particular batches.

If your production method includes the use of additives with either SVO or UCO (or both) you should be aware that there are restrictions on the use of ‘tied’ oils, which are relieved of duty except when used as motor fuels. You can find more information on tied oils in Get relief for mineral oil put to certain uses (Excise Notice 184A). Marked or rebated fuels (such as red diesel and kerosene) must not be used as road fuel or as additives in road fuel. More information can be found in Registered Dealers in Controlled Oil (Excise Notice 192).

If you need more advice you should contact the Excise enquiries helpline.

3.3.1 How to prove that your fuel is biodiesel

We expect that anyone producing biofuels commercially will have their fuel analysed and tested on a regular basis as a part of normal quality control. These tests should give details of the sulphur or ester content and ideally show a breakdown of the composition of the fuel.

The recipe or formulation for biodiesel production will often be enough to determine whether the finished product can meet the full biodiesel specification. For example, anything that would reduce the ester content below 96.5% through having a low or nil ester content itself, for example, alcohol, terpine or water. However, the recipe alone does not provide proof that a product meets (or fails to meet) the specification.

Tests should be carried out on the ‘finished fuel’ and not on the raw materials used in production. Producers should make sure that the fuel that is tested does not undergo any further process and that it’s identical to the fuel put out for sale.

3.3.2 Frequency of testing

Testing should always be done when there are changes in the recipe and either or both of the:

• raw materials used

• production method

The following table is a guideline to the minimum frequency and level of tests HMRC expects.

Production (litres per month)	Frequency of testing
Below 1,000	Annually
1,000 to 5,000	Six monthly
5,001 to 10,000	Quarterly
10,001 to 30,000	Monthly
Above 30,000	By batch

3.4 Bioethanol

Bioethanol is a liquid fuel consisting of ethanol produced from biomass that is capable of being used for the same purposes as light oil. The duty rate of bioethanol at the time of publication is the same as that of unleaded petrol.

We have approved 2 formulations of denatured alcohol for use in the manufacture of bioethanol intended for blending with petrol for use as either road fuel or the production of biodiesel (or both). The 2 formulations are described in paragraph 3.4.1.

3.4.1 Trade specific denaturants for alcohol (TSDA)

The approved formulations are:

• TSDA 9 – a maximum of 99% ethanol and a minimum of 1% methanol with 10 micrograms per millilitre of denatonium benzoate added to the resulting mixture - the approved use is for blending with petrol to be used as a road fuel or to produce biodiesel in a tax warehouse

• TSDA 11 – blending with unleaded petrol with a Research Octane Number (RON) greater than 91 – 1% volume - the approved use is as a road fuel

Denatonium benzoate is a proven denaturant and the level of addition of methanol (which acts as a chemical marker) falls within the agreed standard for BS EN228.

More information on denatured alcohol is available in Production, distribution and use of denatured alcohol (Excise Notice 473). If you want to make applications for new denaturant formulations, see sub-paragraph 3.4.6.

3.4.2 Bioethanol blend brought into the UK

If the bioethanol, which can originate from inside or outside the UK, is denatured according to the exporting country’s regulations, and the blend is the finished product (for example, E5, E85, E92) the UK will accept it as being a fully denatured alcohol, meeting the specification requirements in HODA 2AB (3).

If denatured bioethanol brought in from another country is not a finished product it must either:

• be denatured according to the UK formulation

• satisfy us that it has been denatured as closely as possible to UK formulation (Denatured Alcohol Regulations - Regulation (4)(6))

A finished product in these circumstances means fuel that is not subject to further processing or blending (or both) before being delivered for general sale, apart from proprietary additives such as performance and cold-start treatments.

3.4.3 Bioethanol blend imported from other countries

For the fuel to be treated as a bioethanol blend under HODA 2AB (3), bioethanol blend denatured by a country outside the UK must either:

• be denatured in accordance with the UK regulations (see sub-paragraph 3.4.1)

• satisfy us that it has been denatured as closely as possible to one of the UK formulations (Denatured Alcohol Regulations – Regulation (4)(7))

3.4.4 Bioethanol – denatured to the approved UK formulation

Bioethanol produced in approved premises, which is denatured according to 1 of the UK formulations and set aside as road fuel, is liable to the bioethanol rate of duty (HODA 6AD).

3.4.5 Bioethanol producers

Producers of bioethanol must hold a distiller’s licence and obtain approval of plant and production process. Read Notice 39: spirits production in the UK for more information.

If producers who hold a distiller’s licence want to denature bioethanol, they must still be authorised by us to do so. Anybody else who wants to denature bioethanol must apply for a licence and obtain approval of plant and production process. Recipients of denatured bioethanol must also be licensed.

Once bioethanol is produced it’s liable to alcohols duty. It becomes exempt from alcohols duty once it is denatured (Section 5(1) of FA95). However, although there’s no alcohols duty on the denatured bioethanol, a trade specific denatured alcohol (TSDA) remains subject to obligations under the alcohols regime until it’s put to its intended use (Denatured Alcohols Regulations 2005).

3.4.6 Alternative TSDA formulations

We will consider applications for alternative TSDA formulations, but any new formulations must provide a similar level of revenue protection to that of the existing formulations. It may be worth contacting a licensed or authorised denaturer with your proposals to make sure that your formulation can be produced.

Before a new TSDA is approved, you must supply enough evidence that the existing approved denatured alcohols, including TSDAs, are unsuitable for your intended purpose.

Guidance on the obligations of producers and recipients of denatured bioethanol, as well as the process for applying for a new TSDA, are contained in Production, distribution and use of denatured alcohol (Excise Notice 473).

3.5 Ethyl tertiary butyl ether (ETBE)

ETBE is produced by mixing ethanol and isobutylene and reacting them with heat over a catalyst. ETBE can then be blended with petrol or burnt in an engine for use as a road fuel. Blends of ETBE and petrol are treated as bioethanol blend under HODA 6AE upon its importation or release from a tax warehouse - it is charged to duty at a composite rate in accordance with that section.

ETBE produced from synthetic ethanol is a fuel substitute liable for duty at the rate for unleaded petrol.

ETBE or petrol blends will not require a further denaturing process, but like bioblend, ETBE or petrol blends must be produced in a tax warehouse. Following production of ETBE or petrol blends, the ethanol used in the manufacture will no longer be considered an alcohol for spirits duty purposes and will instead be treated as a motor and heating fuel.

3.6 Movements of biofuels

Biodiesel and bioethanol that are to be used in the production of another product, such as bioblend, can be designated as ‘process oils’ – see Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179). Warehousekeepers and producers may deliver process oils without payment of excise duty as long as they move between tax warehouses.

Denatured bioethanol can be moved without payment of duty provided it originates from a tax warehouse and the purpose of the movement is to allow either blending with light oil in another tax warehouse or in the production of biodiesel, also in a tax warehouse.

The Excise Warehousing (Energy Products) Regulations 2004 provide for ‘special energy products’ such as biodiesel to be stored and moved without payment of excise duty. Such movements are subject to the usual conditions (such as the use of accompanying documents).

4. Accounting for excise duty

4.1 When excise duty is chargeable

Excise duty is due on the setting aside (see paragraph 4.2) or use of biofuels for a ‘chargeable use’. ‘Chargeable use’ means the use of that substance either:

• as a fuel for any engine, motor or other machinery

• as an additive or extender in any substance used as fuel for any motor, engine or other machinery

• for the production of bioblend or bioethanol blend

Excise duty is not chargeable if you set aside or use biofuel:

• as a heating fuel

• for any other non-motor fuel use

See section 5 regarding the mixing of biodiesel and bioblend with rebated heavy oil. Biofuel producers (and motor and heating fuel users in general) need to register their business and tell HMRC about (‘make entry of’) their production premises if they produce 2,500 litres or more a year. This includes producers of 100% heating fuel.

4.2 When excise duty is payable on biofuels

The excise duty point for biofuels is the time when they’re:

• sent out from entered premises

• set aside

• used as a motor fuel

‘Set aside’ means the point at which it’s decided that the product is going to be used as a motor fuel. This decision means that the fuel has been set aside for a chargeable use.

Duty is not due if it’s used as a heating fuel.

4.2.1 Exempt producers or users

You’re exempt and do not need to register and account for duty if in the last 12 months you’ve produced or used, or expect to produce or use in the next 12 months, less than 2,500 litres of either any:

• biofuel

• other fuel substitute or additive

However, there are simple record keeping requirements, which are described in paragraph 4.10.1.

Production includes the manufacture or processing of road fuel, and the setting aside of any product that has not been charged with duty, with the intention of using it as road fuel or for any other engine or machinery except for heating.

4.2.2 Large producers

HMRC will contact you and send you monthly returns if in the last 12 months you’ve produced, or expect to produce in the next 12 months, 450,000 litres or more of:

• biofuel

• other fuel substitute or additive

If you’re a large producer who has produced less than 450,000 litres in the last 12 months and you do not expect to exceed the amount in the next 12 months, you should contact the MORC helpline.

4.2.3 Producers sharing premises and equipment

Regulation 8A of the Biofuels and Other Fuel Substitutes (Payment of Excise Duties etc) (Amendment) Regulations 2007 (SI 1234 of 2007) which came into force on 30 June 2007, has a condition that separate producers at the same premises or sets of premises must register and account for duty if the total of that production is 2,500 litres or more a year. The threshold does not apply separately to each individual producer at the same premises - or sets of premises. The producers must register if total annual production at the same premises or sets of premises is 2,500 litres or more.

Partnerships, collectives and cooperatives (including non-profit making organisations) are liable to register and account for duty if total annual production is 2,500 litres or more.

4.2.4 Vegetable oilused or sold as motor fuel free of excise duty

Vegetable oil (unused and used, processed or unprocessed) that is set aside or intended for use as motor fuel is liable to duty unless the producer is exempt.

Vegetable oil producers and retailers who make and supply their oils for cooking are not liable to register and account for duty on their sales if the oil is subsequently used as, or to produce, motor fuel. Cooking oil producers and retailers who supply direct to fuel producers and distributors are not liable for duty unless they have set aside all or part of their production as motor fuel. In these scenarios it is the fuel producer or distributor who is liable to register and account for duty.

4.3 If you import special energy products and bioethanol

If special energy products and bioethanol intended for the production of bioethanol blend are delivered direct to an excise warehouse, then duty may be suspended until the product leaves the warehouse. The duty point will be the point at which the product is released to home use.

Normally, products travelling under duty suspension must be accompanied by the appropriate accompanying documentation. If you’re in doubt as to whether your product requires accompanying documentation, you should check with the Excise: enquiries helpline.

Bioethanol can only be imported into an excise warehouse if it’s intended for blending to make bioethanol blend or for use in the production of biodiesel.

4.4 How to submit returns to HMRC

If you’re not an exempt producer, you need to register your premises.

4.4.1 If you’re not approved for deferment

You’ll need to complete form HO930 quarterly, or each month if you’re a large producer (see paragraph 4.2.2).

If you do not use or set aside any biofuels in any given return period you should still send in form HO930 showing a nil liability.

4.4.2 If you are approved for deferment

You will need to complete form HO10. Further details are given in paragraph 4.7 below.

4.4.3 When to complete returns

Completed returns and payment must be received by the 15th day of the month following the end of each return period.

For example, if your return period ends on 30 June we must receive your return and payment by 15 July. When the 15th day is not a business day, the return and payment is due on the last business day before the 15th of the month.

If there’s a change of duty rate during the accounting period then you need to keep a clear record of how you accounted for duty using the correct rates at the correct times.

4.5 How to pay excise duty

You can approve a payment through your online bank account by following the instructions for Pay duty on biofuels or gas for road use.

If you pay by Bacs (Bankers Automated Clearing System) or CHAPS (Clearing House Automated Payment System), use the following bank account details:

HMRC bank account details

Account name: HMRC General BT Receipts account
Sort Code: 20-05-17
Account Number: 40204374
BIC: BARCGB22
IBAN: GB86BARC20051740204374

If you pay by cheque, send it to:

HMRC Direct
BX5 5BD

Make your cheque payable to ‘HM Revenue and Customs only’ followed by your biofuels registration number.

4.6 How to account for the excise duty due on bioblend and bioethanol blend

Blending biodiesel or bioethanol with duty suspended oil to produce bioblend or bioethanol blend must be done in a tax warehouse. Duty payment can be deferred if you have a deferment account.

The excise duty due on these blends must be split between the 2 grades on your deferment return (form HO10) and be shown against the appropriate tax types. For example, in the case of bioblend, you must account for duty under tax type:

• 589 for the biodiesel portion

• 541 for the diesel portion

The tax code for bioethanol is 595 and the tax code for unleaded petrol is 522.

In the case of rebated bioblend (for off-road use) you must account for duty under tax type:

• 571 for the rebated biodiesel portion

• 556 for the marked gas oil portion

Blends of kerosene and biodiesel for heating purposes are fully rebated.

You must be able to support the apportionment from your production and blending records. The proportions are to be calculated and shown in your records to the nearest 0.001%.

4.7 Submit your forms online

You can submit forms HO930 and HO10 online. For more information about how to complete these forms, contact us on telephone: 0300 200 3700.

4.8 Deferring excise liability

Subject to the deferment conditions contained in Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179), producers of fuel substitutes, biodiesel, bioethanol and their blends may defer their excise duty. You will need to get a deferment account and make your payments via Bacs or CHAPS.

If you account for your liabilities in this way, you will need to submit a duty account on form HO10 rather than on form HO930.

The standard accounting period currently runs from midnight on the 15th of the month to midnight on the 14th of the following month.

You will also need to provide a guarantee if you’re going to defer your excise duty liability, unless you’re eligible for the Excise Payment Security System (EPSS). At the time of publishing, this guarantee must be sufficient to cover one month’s maximum excise duty liability, or £9.5 million whichever is the lower. Guarantors can still be liable for up to twice the monthly amount shown on the guarantee. Details of how to obtain a deferment account and the excise duty accounting procedures are given in Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179).

4.8.1 Excise Payment Security System (EPSS)

A guarantee is required to cover any deferred payments of excise duty when excise goods (alcohol, tobacco and mineral oils) are removed to the UK home market in any of the following circumstances:

• from an excise warehouse

• upon importation

• when making payments of excise duty on removals from a UK beer, wine, made-wine, cider or perry production premises

However, you can apply for authorisation to make payments without a guarantee under EPSS if you meet the eligibility and authorisation criteria. Read details about the scheme and application forms in Notice 179.

This scheme is not available to Registered Consignee movements in Northern Ireland as European law requires them to be covered by a guarantee. Find more information in Notice 203a: registered consignees.

4.9 How to measure the volume of your product

The law requires excise duty to be charged on litres measured at a standard temperature of 15°C, known as ‘standard litres’. You’re expected, wherever practicable, to account for excise duty using standard litres. In some circumstances it may be impractical or unreasonable to do so, therefore de minimis limits may apply to certain transactions. See Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179) for more details. However, this is not an automatic entitlement and you’ll need to contact the Excise enquiries helpline.

4.10 Records to keep

As a revenue trader you must maintain records relating to your business affairs. These will be your normal business, management and accounting records.

The Biofuels and Other Fuel Substitutes (Payment of Excise Duties, etc) Regulations 2004, as amended in 2007, also need producers to keep and maintain a motor fuels record. The record keeping requirements that apply to registered producers differ depending on whether you’re supplying biofuels to others, or using those that you produce yourself.

The following list shows the requirements.

Supply

Before the product leaves the producer’s premises, record:

• the date of each supply

• a description of each supply

• in the case of a fuel substitute, a description of the type of engine that it is suitable for use in

• the amount, in standard litres, of each supply set aside and sent out for a chargeable use

• the name and address of each person you make a supply to

• the address to which the supply is sent

• the number of the delivery note for each supply made

• the date on which the entry is made in the motor fuels record

• the amount and rate of duty charged on each supply

Own use

No later than the chargeable use occurs, record:

• the date of each chargeable use

• a description of the liquid being used

• in the case of a fuel substitute, a description of the type of engine that it is suitable for use in

• the amount, in standard litres, of biofuels put to a chargeable use

• the date on which the entry is made in the motor fuels record

• the amount and rate of duty due on each chargeable use

You can read the important force of law contained in paragraph 3.3.

Notice 206: Revenue traders records, contains more information about what records you need to keep if you are a revenue trader.

4.10.1 Exempt producers’ records

If you’re an exempt producer you only need to record and keep the:

• date of either each supply or own use (or both)

• amount in standard litres of each supply or own use

You should check the amounts produced at the end of each month. If you have produced 2,500 litres or more in the last 12 months, or expect to produce 2,500 litres or more in the next 12 months, you must contact us within 30 days to register your premises.

The following paragraph has the force of law.

Under the powers given by regulation 6 of the Biofuels and Other Fuel Substitutes Payment of Excise Duties, etc (Amendment) Regulations 2007, HMRC require that the records of litres and dates as specified in paragraph 4.10 below are kept by exempt producers and preserved for 6 years, or for a lesser period if HMRC allow.

4.11 How long must you keep records

Registered and exempt producers must keep records for 6 years. If this will cause you problems you should contact the Excise: enquiries helpline who can advise you about asking for permission to keep your records for a shorter period.

4.12 Keeping paper records

You can keep your records on film or electronically, provided that the records are legible and you provide the necessary facilities to read the records. Notice 206: revenue traders records has more information.

4.13 What to show on delivery notes

Your delivery notes must show:

• the date on which the consignment was sent out

• a description of the consignment of fuel, for example, biodiesel

• in the case of other fuel substitutes, what type of engine the fuel is suitable for use in, see paragraph 2.2 for further details

• the quantity, in standard litres, of fuel sent out, see paragraph 4.9 for further details

• the name and address of the consignee

• the address where the fuel was sent to

• the address from where the consignment was sent

4.14 Placing special energy products or bioethanol in a warehouse under duty suspension

You can place these products under duty suspension in an excise warehouse. However, bioethanol can be placed under duty suspension only for blending with duty suspended oil, or for use in the production of biodiesel. Paragraph 4.3 has more information.

4.15 If you stop producing biofuels

Contact HMRC if you stop producing any of the fuels mentioned in this notice. We can then arrange to cancel any entries of premises, approvals and duty deferment accounts that you may have.

We’ll also advise you about how you may account for any extra duty that may be outstanding.

5. Biodiesel and bioblend for use other than as road fuel

5.1 Duty charged on biodiesel used as heating fuel

Biodiesel for use as a heating fuel is not subject to duty.

5.2 Rate of duty applying to biodiesel for off-road use

Biodiesel intended for use other than as a road fuel is subject to a rebated rate of duty. You can find the current duty rates in Rates and allowances: Excise Duty - Hydrocarbon oils.

5.3 Supplying biodiesel for off-road use

If you supply biodiesel that is intended for use other than as a road fuel, your motor fuels record should contain a description indicating that the biodiesel was set aside for either:

• use other than as fuel for a road vehicle

• an additive or extender to any substance so used

It’s your responsibility to keep evidence of the use to which the fuel has been put.

5.4 Self-supply of biodiesel for off-road use

If you use the biodiesel that you produce for off-road purposes (self-supply) you should apply the appropriate rate and record the supplies in your motor fuels records. You should make sure that you retain evidence of the use that the fuel is put to.

5.5 Marking rebated biodiesel

At present there’s no requirement to mark rebated biodiesel, but this will be kept under review. However, paragraph 5.8 explains the marking requirements when rebated biodiesel is blended with gas oil and kerosene.

5.6 Buying biodiesel for off-road use at the road fuel duty rate and claiming the duty difference from HMRC

The repayment scheme allowing users to reclaim the duty difference of the road fuel rate and off-road rate was cancelled in April 2008. Suppliers of biodiesel for off-road use should charge you the rebated rate. Paragraph 5.13 explains more about biofuels and electricity generation.

5.7 Rates of duty that apply to bioblends used other than as road fuel

In the case of bioblend produced with rebated gas oil, the:

• biodiesel component is subject to the rebated biodiesel rate of duty

• gas oil component is subject to the rebated gas oil rate of duty. This rate applies to all uses other than as road fuel

In the case of biodiesel produced with kerosene for heating use, both the biodiesel and the kerosene components are subject to a full rebate of duty, so there’s a nil duty rate. However, no rebate is permitted where biodiesel mixed with kerosene is used as motor fuel (on or off-road). The duty rate for these mixes is the rate applicable to (non-rebated) bioblend and will be accounted for at the biodiesel rate for the biodiesel portion and the heavy oil rate for the kerosene portion as described in paragraph 4.6.

5.8 Marking rebated bioblend

Rebated bioblend must be marked to qualify for the rebate. The marking requirements for rebated bioblend produced with gas oil are as though the mixture consisted entirely of gas oil. The marking requirements for rebated bioblend produced with kerosene are as though the mixture consisted entirely of kerosene.

Information on the requirement for marking rebated fuels is contained in Section 8 ofMotor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179).

5.9 Supplying bioblend for off-road use

If you supply rebated bioblend, you’re required to be a Registered Dealer in Controlled Oil (RDCO) and to comply with the requirements of the scheme (refer to Registered Dealers in Controlled Oil (Excise Notice 192) for guidance). This requirement does not apply to suppliers of rebated biodiesel (not in a blend).

5.10 Mixing biodiesel or bioblend with rebated oil

If mixing of biodiesel with oil takes place before the duty point, a bioblend is created, and duty should be charged accordingly.

If biodiesel on which duty has not been charged is mixed with oil on which a rebate of duty has been allowed, no duty is chargeable on the biodiesel if it’s intended that the mixture will be used for heating.

There’s no restriction on mixing rebated biodiesel or partially rebated bioblend with any rebated oil, provided it is not intended the mixture will be used as road fuel.

There’s no restriction on mixing fully rebated bioblend with any rebated oil, provided it’s not intended the mixture will be used as fuel for a road vehicle or any engine.

5.11 Using rebated biodiesel or bioblend as fuel in a road vehicle

It’s illegal to use these fuels in a road vehicle unless you pay the difference between the full rate of duty on the fuel and the rebated rate actually paid on the fuel used. Read Fuels for use in vehicles (Excise Notice 75) for guidance.

5.12 Penalties for the misuse of rebated biodiesel or rebated bioblend

The penalties that apply to misuse of rebated biodiesel or rebated bioblend are the same as the misuse of rebated oil. Read Fuels for use in vehicles (Excise Notice 75) for guidance.

5.13 Biofuels and electricity generation

Part 7 of the Biofuels and Other Fuel Substitutes (Payment of Excise Duties) Regulations 2004 allows relief from duty on biofuels used for electricity generation. This relief applies to all biofuels; it’s not restricted solely to those that meet the biodiesel specification. Relief can only be claimed by the ‘qualified claimant’. A qualified claimant is a person who uses biofuel to generate electricity.

If you’re approved for deferment, you should set-off the relief against your normal excise duty liability in the Duty Claimed section of form HO10.

If you’re not approved for deferment then you should set-off the relief against your normal excise duty liability on form HO930.

In any other case, you’ll need to make a claim in writing to the MORC.

Claimants should use form EX55. Form EX55 can also be used to claim back duty paid on gas oil used to generate electricity. Read Motor and heating fuels used to generate electricity - relief from Excise Duty (Excise Notice 175) for more information.

The claim should then be sent, together with any supporting documentation, to the MORC address.

In all cases, we may ask you to provide evidence to substantiate your claim. These may be in the form of purchase orders, delivery notes and sales invoices, to show that the biofuel in question has been used as fuel to generate electricity. You may also need to provide evidence that the biofuels were duty-paid and are not the subject of any other application or claim for repayment, remission or drawback.

For more information, contact the Excise: enquiries helpline.

5.14 Bioblend and electricity generation

The Hydrocarbon Oil, Biofuels and Other Fuel Substitutes (Determination of Composition of a Substance and Miscellaneous Amendments) Regulations 2008 allow relief, in certain circumstances, from duty on bioblend used for electricity generation. This extends the relief given to rebated gas oil to include bioblend. Details of qualification for the relief and claim procedures are contained in Motor and heating fuels used to generate electricity - relief from Excise Duty (Excise Notice 175).

5.15 Treatment of duty paid fuel which has been accidentally mixed or become contaminated (also known as ‘slops’)

When motor fuel is delivered to home use on payment of duty and subsequently becomes contaminated, or accidentally mixed, a credit of excise duty may be allowed under the provisions of HODA 1979 Section 20. Procedures to follow in such cases are set out in Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179). The introduction of rebated biodiesel and bioblend from 1 April 2008 means that most duty paid fuel consignments will contain varying proportions of biofuel and there may not be a clear audit trail to establish the exact amount if the fuel is contaminated or accidentally mixed. The following paragraphs explain the procedure to follow.

5.15.1 Establishing the biodiesel content of contaminated or accidentally mixed fuels - sent for marking or flushing into marked stock

1. Where industrial gas oil is marked at a duty-paid terminal the assumption will be that there’s no biodiesel component, as there’s no (current) commercial reason why biodiesel should be present.

2. Where automotive gas oil (AGO) is marked at a duty paid terminal, unless there’s an audit trail to show the exact biofuel content, it will be assumed that the AGO has been blended with 5% biofuel.

Read section 5 of Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179) for more information.

5.15.2 Establishing the biodiesel content of contaminated or accidentally mixed fuels - returned to producer

1. Where there’s an audit trail to show that the fuel came from blended stock and the blend ratio can be established (for example, the producer has a 4.6% biofuel blend ratio for the period covering the delivery) this should be used to calculate the biodiesel element.

2. If the fuel comes from distribution terminals delivering from unblended stock it will be assumed that there’s no biofuel element.

3. If the fuel comes from distribution terminals delivering from both unblended and blended stock and can be traced as coming from blended stock, it should be assumed to contain a 5% biofuel element unless the blend ratio can be established. If the blend ratio can be established (as at (a) above) it should be used to calculate the biofuel element.

4. If the fuel cannot be traced back to blended or unblended stock the biofuel element may either be assumed to be 5% or be established by laboratory analysis. Laboratory analysis will be used to settle any disputes or doubts about the biofuel content and can be conducted at the duty suspended premises to which the fuel is returned or at an independent laboratory.

5.15.3 Record keeping and evidence required

The details which must be recorded by the receiving warehouse keeper or at the remote marking premises are set out in paragraphs 5.8.4 and 5.8.5 of Motor and heating fuels general information and accounting for Excise Duty and VAT (Excise Notice 179). Independent laboratory analysis is not a requirement for establishing the biofuel element.

Examples of audit trail documentation are:

• a suppliers invoice in respect of the related original delivery showing that a duty inclusive price had been paid

• a statement from the supplying oil company (duty payer) that the delivery into the stock of source location was duty paid, if possible giving vessel name or parcel reference with the date of arrival - if so, the volumes should be matched against a cargo delivery ex-refinery or warehouse to the duty-paid location, the oil company will then be able to confirm that duty was paid on the cargo and included in form HO10 for the period of the 15th of the month to the 14th with payment on the 30th

• if it’s not possible to match the delivery into the source locations stock with a particular movement: a statement from the supplying oil company, confirming that duty has been paid on all bulk deliveries to the location and that the delivery/deliveries concerned have all been drawn from stock on which duty has been paid via the deferment arrangements
