Consultation outcome

Updating GB type approval for road vehicles

Updated 6 March 2024

Applies to England, Scotland and Wales

Introduction

Motor vehicles are required to be type-approved against safety and environmental rules before they go on sale. This enables government agencies to ensure that manufacturers are producing vehicles that comply with the safety and environmental obligations set out in legislation.

We have recently introduced an independent type approval scheme, GB type approval.

Manufacturers currently using provisional GB type approval, which recognises vehicles approved to EU requirements, for road vehicles will need to apply to the Vehicle Certification Agency (VCA) for GB type approval.

For motor vehicles, this applies to new models introduced to the market on or after 1 February 2024, and to all models which are to be produced on or after 1 February 2026. For trailers towed behind motor vehicles, the applicable dates are one year later, in other words 1 February 2025 and 1 February 2027.

In the last few years there have been numerous developments in vehicle regulations internationally, and we are in the process of considering whether these should be incorporated in the GB scheme.

This consultation covers 2 proposals:

We propose to accept approvals to some international (UNECE) regulations which the UK has signed and thus undertaken to accept. The most important proposal here is whether to accept the latest internationally agreed emissions standards for cars and light goods vehicles, sometimes known as Euro 6e.

We have identified some subjects which are of lower priority in safety or environmental terms. We are considering whether to permit manufacturers to test to certain alternative specifications in these subjects, that provide the same or a comparable level of safety or environmental protection. This consultation proposes to accept one specification used in an international market, which industry has identified as beneficial. A future consultation will seek your detailed views on this concept.

UNECE regulations

There is a great deal of international harmonisation of road vehicle regulations, chiefly via the United Nations Economic Commission for Europe, or UNECE.

The UK is a contracting party to the UNECE’s 1958 Agreement, Revision 3.

This is an international agreement relating to reciprocal recognition of vehicle approvals.

Governments (‘contracting parties’) that sign up to an internationally agreed specification (‘UNECE regulation’) are permitted to issue approvals to vehicles or components that comply with that regulation. Contracting parties must accept vehicles and components type-approved by another contracting party against a UNECE regulation that they are a signatory to.

The benefits of international harmonisation include that it reduces the complexity faced by manufacturers in attempting to understand and test vehicles to numerous national standards, and gives rise to economies of scale in manufacture, thus lowering costs.

We are proposing to update domestic legislation to ensure that the scheme accepts UNECE regulations that the UK has signed and thus indicated that it will accept, for subjects that currently form part of the GB type approval scheme. This includes UNECE regulations covering the latest Euro 6e emissions standards for cars and light goods vehicles, facilitating the sale of cleaner vehicles in Great Britain, and permitting manufacturers to sell the same specification of vehicle in Britain as they sell in Europe and Northern Ireland.

Emissions regulations

The new GB Whole Vehicle Type Approval scheme (GB WVTA) becomes mandatory for all new vehicle types from February 2024, and all models which are to be produced on or after 1 February 2026 of motor vehicles for carrying passengers or goods (known as categories M and N). Within this, vehicles have to be tested for pollutant emissions.

The current Euro 6 emissions standard which applies to light duty vehicles (cars and vans) contains sub-steps indicated by letters, with the GB scheme currently requiring Euro 6d.

Internationally, the UNECE have very recently adopted the Euro 6e standard. The EU have also adopted Euro 6e into their type approval scheme which applies to vehicles sold in Northern Ireland under the obligations set out in the Windsor Framework, and thus Euro 6e will become compulsory for vehicles sold in Northern Ireland in due course.

Euro 6e includes changes to the laboratory and on-road test procedures. Overall, it is a more stringent environmental requirement for vehicle manufacturers to meet than Euro 6d, but certification to Euro 6e does not automatically guarantee compliance with Euro 6d.

Manufacturers who operate in both EU and GB markets have indicated that they intend to sell models of vehicle complying with Euro 6e in both markets but would naturally prefer not to also test those models against the Euro 6d requirements, which would amount to double testing.

We are therefore proposing to amend our regulations to permit manufacturers to use the UNECE Regulations which contain the Euro 6e requirements (listed in Table 1) to certify compliance with GB requirements for Euro 6d. This will permit cleaner vehicles, improving air quality, without the manufacturers incurring the cost of double testing.

Manufacturers will be allowed to continue to produce Euro 6d vehicles for the market in Great Britain until further notice: they can continue to demonstrate compliance via Euro 6d testing. Future emissions requirements for vehicles to be sold in GB are being assessed and may be consulted upon in future.

There is a similar situation for heavy-duty vehicles: buses and heavy goods vehicles. The Euro 6 step E emissions standard is specified in UNECE Regulation 49 and is compulsory for new vehicles sold in Northern Ireland, while step D applies in GB, although we understand that the majority of heavy vehicles sold in GB already comply with step E.

Other requirements

We have reviewed the latest UNECE regulation on tyre Installation (Regulation 142) and it is identical to the GB requirements for tyres. We therefore intend to give effect to our international obligations by referring to it in the GB type approval scheme.

Regulation (EU) 2018/858 sets the type approval framework for the EU, and the retained version of this regulation is still applicable in Great Britain and with numerous amendments forms the basis of the GB type approval scheme. There are some UNECE Regulations which were previously accepted, but due to an error in Regulation (EU) 2018/858, are no longer specified. We will take this opportunity to correct our legislation, and update footnotes which were previously applicable when we were an EU member state. This is outlined in Table 1.

New electric vehicles are very quiet so are required by law to emit a special sound at low speeds, to assist groups such as the blind who might not otherwise be aware of their presence. UNECE Regulation 138 on Quiet Road Transport Vehicles (QRTV) regulates this special sound and has been signed by the UK so needs to be accepted in the GB scheme.

We propose that the GB scheme should accept solely the 138.01 series of amendments, and not the earlier 138.00 series of amendments. This is in line with the relevant retained law, Regulation (EU) 2019/839, where a pause function on the acoustic vehicle alerting system (AVAS) is now prohibited on the newest vehicles.

As we are making corrections, we also propose to make a correction which will ensure that tyre manufacturers can be appointed as a technical service for the purposes of assessing tyre rolling resistance in the CO2 calculation scheme for heavy lorries, known as VECTO. This was previously permitted but was omitted due to an error in Regulation (EU) 2018/858.

Lower priority subjects and alternative specifications

There are around 70 subjects in GB approval where vehicles are required to be tested, depending on category. For a large proportion of these, UNECE regulations exist, thus minimising the test burden on manufacturers, as they are likely to be obtaining the UNECE approvals for a variety of other markets.

For the remaining subjects not covered by UNECE regulations, there are unique GB specifications in around 20 areas. After careful consideration, we have decided that there may be benefits from giving manufacturers the choice of testing to alternative requirements to those currently laid out in the approval scheme.

This would initially be limited to the subjects where we are confident that the impact on safety or the environment of accepting alternative standards is limited or non-existent, but where the benefit to manufacturers of accepting alternative, equivalent, specifications from other markets may be substantial.

Industry have flagged that the technical specification for the rear registration plate space in EU approval (Annex III to Regulation (EU) 2021/535) has diverged from that in GB approval, and that it would be a priority for them if we could accept the equivalent EU specification. The differences do not affect safety or the visibility of the plate so we consider it appropriate to accept this.

As a first step, therefore, we propose to accept vehicles meeting the EU specification for rear registration plate space. This would be demonstrated by a test report from a designated technical service. The VCA as the GB approval authority will retain the ultimate say over whether the test report is an acceptable demonstration of compliance.

We will be requesting comment on additional potential changes of this nature in due course.

[1] The numbering of the entries in this table refers to the numbering used in the table of Part I of Annex II to Regulation (EU) 2018/858 as it applies in Great Britain.

[2] For pure electric vehicles, evidence of compliance with paragraph 3 (a) (ii) of the Regulation (anti-tampering measures applied in relation to the odometer) is considered as equivalent to holding an approval to this regulation.

[3] In addition, paragraph 4(3) of Schedule A1 of the Road Vehicles (Approval) Regulations 2020 (SI 2022/1273) applies.

[4] The component type-approval provided for in the UN regulation of hydrogen storage systems, automatic shut-off valves, check or non-return valves and thermally activated pressure relieve devices is mandatory. Also, the UN regulation does not cover the obligatory material qualification of all components that are covered by Article 2(2) of Regulation (EC) No 79/2009 of the European Parliament and of the Council.
