Fly-tipping statistics for England, 2021 to 2022

Updated 25 August 2023

Applies to England

This statistical notice provides statistics on fly-tipping incidents recorded by Local Authorities in England, for April 2021 to March 2022. It covers trends in the number of fly-tipping incidents, with a breakdown by land type, waste type and size. It also covers enforcement and prosecution actions undertaken for fly-tipping incidents. It excludes the majority of private-land incidents and large scale incidents dealt with by the Environment Agency.

1. Key points

  • For the 2021/22 year, local authorities in England dealt with 1.09 million fly-tipping incidents, a decrease of 4% from the 1.14 million reported in 2020/21.
  • The percentage of fly-tips involving household waste has fallen from 65% to 61% in 2021/22. Total incidents involving household waste were 671,000 in 2021/22, a decrease of 9% from 740,000 incidents in 2020/21.
  • The most common place for fly-tipping to occur was on highways (pavements and roads), which accounted for over two fifths (43%) of total incidents in 2021/22, the same as in 2019/20 and 2020/21. In 2021/22, the number of highway incidents was 464,000, which was a decrease of 5% from 486,000 in 2020/21.
  • The most common size category for fly-tipping incidents in 2021/221 was equivalent to a ‘small van load’ (32% of total incidents), followed by the equivalent of a ‘car boot or less’ (26%).
  • In 2021/22, 37,000 or around 4% of total incidents were of ‘tipper lorry load’ size or larger, which is a decrease of 3% from 38,000 in 2020/21. For these large fly-tipping incidents, the cost of clearance to local authorities in England in 2021/22 was £10.7 million, compared with £11.6 million in 2020/21.
  • Local authorities carried out 507,000 enforcement actions in 2021/22, an increase of 52,000 actions (11%) from 455,000 in 2020/21.
  • The number of fixed penalty notices issued was 91,000 in 2021/22, an increase of 58% from 57,700 in 2020/21. This is the second most common action after investigations and accounted for 18% of all actions in 2021/22.
  • The number of court fines issued nearly tripled from 621 in 2020/21 to 1,798 in 2021/22 (190%), with the value of total fines more than doubling from £330,000 in 2020/21 to £840,000 in 2021/22 (154%).

2. Background on data reporting and data caveats

These data are based on incidents and actions reported through WasteDataFlow. The intention is to capture all fly tipping incidents, whether reported by staff or customers, and enforcement actions taken by local authorities in response to fly tipping incidents.

Local authorities gather their data from a number of different sources, and data can often be collected and reported by separate teams. There is a level of discretion in applying the reporting guidance. This can lead to some differences in how local authorities record incidents. The nature of fly-tipping means that there can be relatively high variation between years and between local authorities. Changes in data collection and reporting over time mean that trends should be interpreted with caution.

We had been aware of a small number of local authorities who were only reporting customer or staff reported fly-tipping incidents for the detailed breakdown by local authority. Until 2018/19, we had been able to estimate all incidents in the total incidents figure for England, to retain consistency of the national headline figure. In 2018/19, Defra were aware that four local authorities had provided figures based on customer reported fly-tips only.

To determine the extent of this and to improve the transparency in reported data, Defra undertook an exercise with all local authorities for their 2019/20 data to ask whether they were reporting the number of incidents for customer reported, staff reported or both customer and staff reported incidents.

This showed that the majority of local authorities are reporting all fly-tipping incidents, whether reported by staff or customers in 2019/20. Around 10% of local authorities reported that they were either just providing figures based on customer reported fly-tips only, or just those incidents reported by staff. We have followed up with local authorities to remind them of their reporting obligations. For more detail, see the reporting basis section.

From 2019/20, for those local authorities that are not reporting ‘all incidents’, no estimates have been made for ‘all incidents’. This is due to the number of local authorities concerned and lack of data to make reliable estimates for ‘all incidents’. The reporting basis for each local authority is available in the published dataset.

2.1 Revisions

Revisions have been made to 2020/21 incidents data for Croydon and Oldham and actions data for Bury, South Tyneside and Winchester. Revisions have also been made to 2019/20 incidents data for Hackney. Actions data for Brent for 2017/18 to 2020/21 have been updated. These revisions have been made due to new or revised data being received after publication. For more detail, please see the revisions section.

2.2 Impact of coronavirus (COVID-19) on fly-tipping

The 2020/21 reporting period covered the first year of the COVID-19 pandemic, and this may have had an impact on incidents and actions for that year, so this may affect comparability with the 2021/22 data. For more detail, please see the Impact of coronavirus (COVID-19) on fly-tipping section.

2.3 Assessing the figures

In assessing the figures, local authorities should not be ranked or classified as ‘good’ or ‘poor’ performers based purely on numbers of fly-tips. Direct comparison between local authorities is not appropriate and especially where the local authority may be reporting on staff and/or customer incidents. The situation is complex and can be influenced by population density, housing stock, demographics and commuter routes. Those reporting higher incident numbers are often those being more pro-active and rigorous in identifying incidents by encouraging the public to report incidents, training of street crews, and increased use of more sophisticated methods for capturing and reporting incidents. Defra is also aware that the definitions used to describe fly-tips in the guidance are interpreted broadly by local authorities.

Trends over time for a particular local authority may be a fairer comparison but many local authorities have changed the way they capture and report fly-tips over the past few years, so the changes over time should still be interpreted with some care. A time series of total incidents for each local authority is available for download. The detailed dataset makes clear the reporting basis for each local authority.

Cost data is only published for clearance costs for ‘tipper lorry load’ and ‘significant/multi load’ incident categories and enforcement costs for ‘prosecutions’ and ‘injunctions’ action categories, which are reported directly by local authorities.

Please note that due to high numbers of incidents being reported as ‘other unidentified’ for land type and waste type in 2021/22, some caution is needed in the interpretation of year-on-year changes.

Percentage changes presented in this statistical notice are based on unrounded figures.

Further information about the data is available at the end of this release.

3. Total number of fly-tipping incidents in England

Figure 1: Total number of fly-tipping incidents in England, 2015/16 to 2021/22

In 2021/22 there were 1.09 million incidents reported.  This is a decrease of 4% from 2020/21.

Equivalent figures for 2007/08 to 2014/15 can be seen in the accompanying dataset.

Please note that from 2019/20, the national totals for fly-tipping incidents are not comparable to previously published data, due to methodological changes. These methodological changes have been applied to the 2018/19 data to enable comparisons to be made.

In 2021/22 there were 1.09 million fly-tipping incidents reported, a decrease of 4% from 1.14 million in 2020/21.

Incidents involving the Environment Agency or cleared by private landowners are not included in this Notice. Details of the 91 incidents of large-scale, illegal dumping dealt with by the Environment Agency in 2021/22 are published separately. Please see the dataset published by the Environment Agency.

In 2021/22 there were on average 19 fly-tipping incidents per 1,000 people in England. London had the highest average number of incidents per 1,000 people at 46, while the South West had the lowest at 9 incidents per 1,000 people.

4. Fly-tipping incidents in England by land type

Figure 3: Fly-tipping incidents by land type in England, 2021/22, compared to 2020/21

Highways have the highest number of incidents, with 464,000 recorded in 2021/22. Commercial/industrial have the lowest number of incidents with 4,000 recorded in 2021/22.

* Other includes agricultural, watercourse and railway.

Highways (pavements and roads) have consistently been the most common land type for fly-tipping incidents over time, accounting for over two fifths (43%) of all incidents in 2021/22. In 2021/22 there were 464,000 incidents, a decrease of 5% from 2020/21 (486,000 incidents).

Fly-tipping on council land was the next most common land type for fly-tipping incidents, accounting for 17% of all incidents, with ‘footpaths and bridleways’ next (15%). Incidents on council land such as housing estates, car parks, parks and offices decreased by 5% to 185,000 incidents from 196,000. Footpath and bridleway’ incidents decreased by 15% to 168,000 from 199,000 incidents.

Fly-tipping incidents in back alleyways amounted to a further 10% of all incidents (106,000 incidents) in 2021/22, a decrease of 12% from 120,000 in the previous year.

5. Fly-tipping incidents in England by waste type

Most fly-tipping incidents are household waste (the sum of ‘black bags’ and ‘other’), which in 2021/22 accounted for 61% of all incidents. The majority of this was ‘household waste (other)’.

Figure 4: Household and commercial waste in England, 2020/21 and 2021/22 (% of total incidents)

Total household waste decreased by 9% from 740,000 incidents in 2020/21 to 671,000 incidents in 2021/22. The majority of fly-tipping incidents are household waste (Other), which was 45% in 2021/22.

Household waste (other) could include material from house or shed clearances, old furniture, carpets and the waste from small scale DIY works.

Commercial waste (other) could include pallets, cardboard boxes, plastics, foam and any other waste not contained in bags or containers and not due to be collected.

Total household waste decreased by 9% from 740,000 incidents in 2020/21 to 671,000 incidents in 2021/22. The household waste sub-categories, ‘black bags’ and ‘other’ decreased by 26,000 incidents (12%) and 44,000 incidents (8%), respectively.

There were 67,000 incidents involving commercial waste in 2021/22, accounting for 6% of total incidents. This was an increase of 9% from the 62,000 incidents reported in 2020/21. There were 33,000 incidents of commercial waste in black bags and 34,000 incidents of other commercial waste in 2021/22.

Types of fly-tipping, other than household and commercial waste – which are construction, demolition and excavation; other unidentified; white goods; green waste; other electrical; tyres; vehicles parts; animal carcasses; chemical drums, oil and fuel; clinical; and asbestos – amount to 32% of all fly-tipping incidents. Within this, vehicle parts, animal carcasses, clinical waste, asbestos, and ‘chemical drums, oil and fuel’ incidents each account for less than 1% of total incidents.

Figure 5: Types of other fly-tipping in England, 2021/22, compared to 2020/21

Other unidentified incidents were the highest with 152,000 incidents recorded in 2021/22. Tyre incidents were the lowest with 15,000 incidents recorded in 2021/22.

* Other Identified includes vehicle parts, animal carcasses, clinical waste, asbestos, and ‘chemical drums, oil and fuel’.

Please note that due to high numbers of incidents being reported as ‘other unidentified’ for waste type in 2021/22, some caution is needed in the interpretation of year-on-year changes. In 2021/22, 152,000 incidents were reported as ‘other unidentified’; this type of waste accounted for 14% of total incidents, an increase from the 11% of total incidents in 2020/21.

For some waste types, such as green waste or electrical goods, it is not always possible to tell whether they originated from households or businesses.

The number of white goods incidents in 2021/22 was 50,000, a decrease of 8% from 2020/21 (54,000 incidents). White good incidents accounted for 5% of total incidents in 2021/22. Green waste accounted for 3% of total incidents in 2021/22. Tyre incidents accounted for around 1% of total incidents in 2021/22.

Incidents with construction/demolition/excavation material decreased by 3%.

6. Fly-tipping incidents in England by size

Incidents recorded by size category relate to those investigated and cleared by the local authority. For a number of reasons, but primarily due to incidents on private land, which an authority may not clear, total incidents by size category may not match total incidents recorded by land type or waste type.

Figure 6: Fly-tipping incidents by size in England 2021/22, compared to 2020/21

In 2019/20, 2020/21 and 2021/22, the majority of fly-tipping incidents were equivalent to a ‘small van load’. The second-largest size category is equivalent to a ‘car boot or less’.

View the data for this chart

Download the data for this chart

As in 2020/21, ‘small van load’ was the largest size category in 2021/22, with around a third of incidents (32% or 341,000 incidents) reported being this size, this is a 10% decrease on 378,000 incidents in 2020/21.

The second-largest size category is equivalent to a ‘car boot or less’. Fly-tipping incidents of this size decreased by 7% from 291,000 incidents in 2020/21 to 271,000 incidents in 2021/22 and made up 26% of all incidents.

‘Single items’, such as furniture, mattresses etc. accounted for 17% of total incidents and have increased by 1%, from 173,000 incidents in 2020/21 to 176,000 in 2021/22.

In 2021/22 ‘Single black bag’ size incidents accounted for 6% of total incidents and have increased by 14%, from 57,000 incidents in 2020/21 to 65,000 incidents in 2021/22.

In 2021/22 ‘Transit van Load’ incidents accounted for 15% of total incidents and have decreased by 1%, from 163,000 incidents in 2020/21 to 162,000 incidents in 2021/22.

In 2021/22, 37,000 or 4% of total incidents were of ‘tipper lorry load’ size or larger, which is a decrease of 3% from 38,000 in 2020/21. For these large fly-tipping incidents, the cost of clearance to local authorities in England in 2021/22 was £10.7 million, compared with £11.6 million in 2020/21.

As noted above, we no longer produce estimates of clearance costs for other size categories.

7. Fly-tipping enforcement and prosecution

As previously mentioned, from 2019/20 national totals for fly-tipping incidents are not comparable to earlier years due to methodological changes. However, data on enforcement and prosecutions actions are not affected so the full time series is presented in this section.

Figure 7: Fly-tipping enforcement actions in England, 2013/14 to 2021/22

There were 507,000 enforcement actions carried out in England in 2021/22, an 11% increase from 2020/21. Investigations are the most common action taken against fly-tipping incidents.

‘Other’ is the sum of stop and search, vehicles seized, formal caution, prosecution and injunction

Equivalent figures for 2007/08 to 2012/13 can be seen in the accompanying dataset.

There were 507,000 enforcement actions carried out in England in 2021/22, an 11% increase (of 52,000 actions) from 455,000 in 2020/21. It should be noted that multiple actions can sometimes be carried-out on one particular incident.

Total enforcement costs have not been estimated for 2021/22 as accurate costs are not available for the majority of enforcement categories.

Investigations have consistently been the most common action taken against fly-tipping incidents over time, accounting for 61% of all actions in 2021/22, with 312,000 investigations in total. This is a decrease of 2% from 2020/21, where 317,000 investigations were carried out.

In May 2016 local authorities in England were given the power to issue fixed penalty notices for small scale fly-tipping. Prior to this date, local authorities issued fly-tippers with fixed penalty notices in relation to littering, duty of care or anti-social behaviour. This fixed penalty notice gave local authorities a more specific fixed penalty notice type, an alternative to prosecutions and a more efficient and proportionate response to small scale fly-tipping. Local authorities are still using the previous fixed penalty notices as well as the new ones.

Further enforcement powers were given to local authorities and the Environment Agency in January 2019, who can now issue fixed penalty notices for breaches of householder duty of care, where householders pass their waste to an unlicensed waste carrier.

Local authorities issued 91,000 fixed penalty notices in total during 2021/22 and these were the second most common enforcement action, accounting for 18% of total actions. The total number of fixed penalty notices has increased by 58% from 57,700 in 2020/21 and continues to show an increasing trend in their use.

Figure 8: Number of Fixed Penalty Notices by type in England, 2020/21 and 2021/22

For 2021/22, 23,700 of the 91,000 fixed penalty notices were issued specifically for small scale fly-tipping, 42,500 in relation to littering, 5,900 in relation to household duty of care and 19,000 in relation to other offences.

* These are FPNs which have been served in relation to fly tipping and other waste offences that are not captured by the other three categories.

For 2021/22, 23,700 (26%) of fixed penalty notices were issued specifically for small scale fly-tipping, 42,500 (47%) in relation to littering, 5,900 (6%) in relation to household duty of care and 19,000 (21%) in relation to other waste offences.

The number of prosecution actions has increased from 721 in 2020/21 to 1,959 in 2021/22 (172%). Costs of prosecution actions increased from £295,700 in 2020/21 to £850,700 in 2021/22 (188%).

There were 54,000 warning letters issued in 2021/22, an increase of 11,000 (26%) from 2020/21. Warning letters accounted for 11% of total enforcement actions in 2021/22.

The number of duty of care inspections rose by 28% in 2021/22, from 20,000 inspections to 25,000 inspections. This accounted for 5% of total enforcement actions in 2021/22.

A total of 21,000 statutory notices were issued in 2021/22, accounting for 4% of total enforcement actions. This was an increase of 41% from the 15,000 statutory notices issued in 2020/21.

The success rates for prosecution actions against fly-tipping are consistently very high over time. Over 100% of prosecutions resulted in conviction in 2021/22, this is due to the fact that more than one outcome can be awarded to a particular prosecution.

The majority of prosecution outcomes are fines, which were issued for 92% of the prosecutions taken against fly-tipping incidents in 2021/22. The number of fines issued nearly tripled from 621 in 2020/21 to 1,798 in 2021/22 (190%), with the value of total fines more than doubling from £329,000 in 2020/21 to £837,000 in 2021/22 (154%).

The number of community service outcomes increased 100% from 15 in 2020/21 to 30 in 2021/22.

8.2 Official Statistics

This is an Official Statistics publication. These statistics have been produced to the high professional standards set out in the Code of Practice for Official Statistics, which sets out eight principles including meeting user needs, impartiality and objectivity, integrity, sound methods and assured quality, frankness and accessibility. For more information, please see the Official Statistics Code of Practice.

9. About these statistics

Fly-tipping is the illegal deposit of waste on land, contrary to Section 33(1)(a) of the Environmental Protection Act 1990. Local authorities and the Environment Agency both have a responsibility in respect of illegally deposited waste. This includes local authorities and the Environment Agency collecting and reporting data on fly-tipping in their area. This statistical notice covers data reported by local authorities in England.

9.1 User Statement

Data on fly-tipping is collected to inform policy making and to provide local authorities with a management tool that enables a problem solving approach to be taken. It records the number of fly-tipping incidents, the type of material tipped, location and size, together with enforcement action taken. The data are used by local and central government, researchers and the public.

9.2 Context

Fly-tipping is a crime, a significant blight on local environments; a source of pollution; a potential danger to public health; a hazard to wildlife, and a nuisance. It also undermines legitimate waste businesses where unscrupulous operators undercut those operating within the law.

Local authorities and the Environment Agency both have a responsibility in respect of illegally deposited waste with certain obligations set out in the Environmental Protection Act 1990. Local authorities have a duty to clear fly-tipped material from relevant land in their areas and consequently they deal with the vast majority of fly-tipping on public land, investigating these and carrying out a range of enforcement actions. The Environment Agency is responsible for dealing with large-scale, serious and organised illegal dumping incidents which pose an immediate threat to human health or the environment. Responsibility for dealing with fly-tipping on private land rests with private landowners and is not subject to mandatory data reporting.

Incidents involving the Environment Agency or cleared by private landowners are not included in this notice. Details of the 91 incidents of large-scale, illegal dumping dealt with by the Environment Agency in 2021/22 are published separately. Please see the dataset published by the Environment Agency.

9.3 Impact of coronavirus (COVID-19) on fly-tipping

The 2020/21 reporting period covered the first year of the COVID-19 pandemic. The first national lockdown introduced in March 2020 led to some local authorities being unable to maintain collections of dry recyclates, with some suspending garden and bulky waste collections. There was also a widespread closure of household waste recycling centres (HWRCs). HWRCs were later re-opened following Government guidance on managing HWRCs in England during the COVID-19 pandemic but with some restrictions in place (e.g. booking system). These factors and other factors such as changes in household consumption, travel and leisure patterns may have contributed to the increases seen in the number of fly-tipping incidents reported for 2020/21.

Staff shortages, staff being furloughed, and staff being redeployed may also have impacted on the number of enforcement actions which were carried out during 2020/21. Courts were also closed at certain points of the reporting period which several local authorities reported impacted on the number of prosecution actions undertaken.

This may affect comparability with the 2021/22 figures, so this should be borne in mind.

9.4 Methodology

These statistics are based on the returns made to the Fly-tipping Module in the WasteDataFlow database by local authorities in England from April 2019 to March 2020. The Fly-tipping Module is the national system used since 2015 to record the incidents and cost of clearing and enforcing against illegally deposited waste by local authorities and the Environment Agency. Detailed guidance is available on the use of WasteDataFlow. Private landowners are not required to report fly-tips on their land, although some choose to do so voluntarily.

It should be noted that the private land data included in this notice do not reflect the full scale of fly-tipping on private land, as most cases go unreported.

The reporting system has been modified to allow more detailed information capture on the individual types of fixed penalty notices issued by local authorities. This has included fixed penalty notices specifically for small scale fly-tipping which were introduced in May 2016 and more recently fixed penalty notices for breaches of householder duty of care which came into force in January 2019.

Local authorities gather their data from a number of sources and departments. Incidents are reported by the public through call centres or online, operatives on the ground collecting and recording, Enforcement Officers, contractors and management companies. Many authorities await verification from investigations before recording public reports as fly-tips.

Data are requested in respect of incidents cleared or investigated by local authorities and, separately, the enforcement actions taken against fly-tippers. These can often be collected and reported by separate teams. Therefore, data can be entered onto the system by one or more persons within an authority. This may lead to some discrepancies and a level of uncertainty. Data verification and quality assurance is carried out by WasteDataFlow personnel and Defra. This is done by a quarterly check of specific aspects of the data to identify significant anomalies which would be queried with authorities.

Until 2017/18, estimate costs for the majority of clearance and enforcement categories were calculated based on typical unit costs for dealing with the different types of incidents/actions. Costs were provided by a small selection of local authorities between 2003 and 2006 when the Flycapture database was being set up. These were used to generate standard unit costs for the clearance and enforcement categories, which were then multiplied up by the numbers of incidents and enforcement actions respectively, in order to generate total cost estimates. The standard unit costs used are detailed in the accompanying notes to the published datasets.

In August 2015 Defra undertook an exercise to update the cost basis by surveying 100 local authorities that had previously indicated a willingness to participate. Unfortunately, both the quantity and quality of response data was insufficient to provide robust factors as replacements. During 2017, Defra carried out some preliminary investigations to source updated costs, but concluded that more targeted and detailed work is required to properly understand the complexities surrounding costs to local authorities. As the standard unit costs are now more than 10 years out of date, the decision has been taken to cease using these from the 2017/18 publication onwards. For the time being only costs for clearance categories ‘tipper lorry load’ and ‘significant/multi loads’, and enforcement categories ‘prosecutions’ and ‘injunctions’ (which are reported directly by local authorities) will continue to be published. Defra is currently considering the feasibility of updating the standard unit costs via research or alternative methodology, subject to resource and other priorities.

9.5 Detailed breakdowns

A breakdown of data for each local authority is available on the Defra website. In assessing the figures local authorities should not be ranked or classified as ‘good’ or ‘poor’ performers based purely on numbers of fly-tips. Direct comparison between local authorities is not appropriate, as there can be some differences in approach where there is a level of discretion in using the guidance on reporting. The situation is complex and can be influenced by population density, housing stock, demographics and commuter routes. Those reporting higher incident numbers are often those being more pro-active and rigorous in identifying incidents by encouraging the public to report incidents, training of street crews, and increased use of more sophisticated methods for capturing and reporting incidents. Trends over time for a particular local authority may be a fairer comparison but many local authorities have changed the way they capture and report fly-tips over the past few years, so the changes over time should still be interpreted with some care. A time series of total incidents for each local authority is available for download. There can be relatively high variation between years and between local authorities.

From 2019/20, incidents per 1,000 people for each local authority have been included in the published dataset.

9.6 Reporting basis

Under Section 71(4) of the Environmental Protection Act 1990 local authorities are required to report information on fly-tipping incidents and actions taken through WasteDataFlow. Details of all fly-tipping incidents, reports, and actions should be reported via WasteDataFlow, including customer reported and those reported by, and pro-actively cleared by staff and contractors.

We had been aware of a few local authorities who were not reporting all incidents or who had changed their basis of reporting.

For the 2019/20 reporting year, Defra undertook a check with all local authorities around the basis of reporting in order to improve transparency in the reported data. An additional question was added to WasteDataFlow to capture the reporting basis for each local authority. The question included was as follows:

The data entries in the Fly-tipping module is a record of fly-tipping offences under s33 of the Environmental Protection Act 1990. We want you to record information for all relevant incidents and actions covering both public reported and those pro-actively cleared by your own and contractors crews. Please select the description that best describes the coverage of your reporting of Fly-tipping incidents and actions:

  1. All incidents i.e. customer/public reported and those reported by, and pro-actively cleared by, your own and contractor crews.
  2. Customer/public reported only.
  3. Staff/contractor and pro-actively cleared only.

This confirmed that the majority (286; 90%) of all local authorities, in 2019/20, were reporting all incidents; 29 (9%) were providing figures based on customer reported fly-tips only, 1 was providing figures based just on those incidents reported by staff and 1 local authority had changed their basis of reporting during 2019/20.

In previous years, estimates were made for ‘all incidents’ for a small number of local authorities where it was known that the local authorities reported figures were not based on ‘all incidents’. These estimated figures were included in the national incident totals but not in the local authority level dataset.

For 2019/20 onwards, for those local authorities that are not reporting ‘all incidents’, no estimates have been made for ‘all incidents’. This was due to the number of local authorities concerned and lack of data to make reliable estimates for ‘all incidents’. This means that the national totals for 2019/20 onwards are not comparable to national totals from earlier years. In order to have comparable data for 2019/20 and 2018/19 we have removed the previous adjustments made to the 2018/19 national figures. These adjustments were made to those few local authorities that were known not to be reporting all incidents, but where the data was available to make the adjustments.

For the revised 2018/19 and the 2019/20 national totals onwards, these only include estimates for non-response and missing data.

The questions on reporting basis have been retained in WasteDataFlow to enable Defra to continue to monitor the basis of reporting. In 2021/22, 275 (89%) of local authorities were reporting all incidents; 26 (8%) were providing figures based on customer reported fly-tips only, 1 was providing figures based just on those incidents reported by staff, 6 local authority had changed their basis of reporting during 2021/22 and one local authority had data that was estimated.

We will continue to encourage local authorities to make all reasonable efforts to report all incidents in future years.

Data on enforcement and prosecution actions is not affected by the methodological change and the time series is presented in this notice.

9.7 Non-response and estimation

In 2021/22, 308 local authorities provided data on fly-tipping incidents and actions. Hackney have not been able to provide data for 2021/22 so an estimate has been made by Defra. This estimate is based on their 2018/19 and 2019/20 return. We did not estimate actions data only incident data.

For 2021/22, four local authorities did not submit data on clearance costs for ‘tipper lorry load’ and/or ‘significant/multi load’ incidents for some or all quarters. These were estimated by Defra based on previous quarters’ data where the figures were consistent or using average 2021/22 unit costs from the known returns or otherwise using an average of previous years’ data for these LAs. These four local authorities were Bristol, Exeter, Folkestone and Hythe and Isle of Wight.

Four local authorities did not submit data on enforcement cost for ‘prosecutions’ for some or all quarters. These were estimated based on using average 2021/22 unit costs from the know returns or otherwise looking at average costs for the LA from previous years. These four local authorities were Ealing, Medway, Sutton and Tunbridge Wells.

Estimates for clearance, enforcement costs and non-response are included in the national totals but are not shown in the local-authority dataset.

Due to higher levels of estimation made from the 2015/16 data, some caution is needed in the interpretation of year-on-year changes.

9.9 Revisions Policy

Defra will provide information about any revisions made to published information in this statistics release and the associated datasets. Revisions could occur for various reasons, including when data from third parties is unavailable or revised data has been input to the Fly-tipping Module of WasteDataFlow.

Prior to the release of this publication, during quality assurance of the 2021/22 data a number of data errors were found in the 2020/21 data. Revisions have been made to 2020/21 incidents data for Croydon and Oldham. Revisions have been made to the 2020/21 actions data for Bury, South Tyneside and Winchester. Revisions have also been made to incidents data for 2019/20 for Hackney. Actions data for Brent for 2017/18 to 2020/21 has been updated to correct an error in the recording of prosecution actions.
