Kidlington dump cleared: 22,105 tonnes taken away

The illegal waste dump beside the A34 at Kidlington has been fully cleared. The Environment Agency says 22,105 tonnes of waste were dug out and taken away, and that concrete blocks and a padlocked gate now close the entrance.

Kidlington is in Cherwell district, about 17 miles south of Banbury and about eight miles south west of Bicester. The site sat on roughly 8,000 square metres of land between the trunk road and the River Cherwell, an area the government describes as larger than the pitch at Wembley Stadium.

The completion was announced on 27 August in a Defra press release. It records:

• 22,105 tonnes of commercial and household waste removed, including tyres, shredded plastic and household rubbish
• four people arrested, with the criminal investigation still running
• concrete blocks at the entrance and the main gate padlocked
• no evidence of harm to the local environment from the regular water sampling

It came out heavier than anyone forecast

Every published estimate was too low. When the clearance began on 14 April, the Environment Agency put the job at “an estimated 21,000 tonnes” and expected it to take around six months. The final figure was 1,105 tonnes higher, and the work finished in about four and a half months.

Oxfordshire County Council’s own interim report to its Place Overview and Scrutiny Committee on 22 April was lower still. It put the mixed shredded waste “in the region of 10,000 tonnes with a reasonable worse case of 20,000 tonnes”.

Part of the reason is that the criminals buried some of it. The Environment Agency’s project page records that when the temporary site compound was lifted in July, more buried waste turned up underneath, hidden by a thick layer of soil when the dumping took place in 2025. One buried pit was about two metres deep and up to ten metres wide. Above ground, the piles had reached ten metres high.

More than 700 lorry loads left the site after clearance began in April. The contractor was Acumen Waste Services Limited, given a direct contract award by the Environment Agency from 19 January 2026.

How it happened, and how long it took

The county council’s report sets out the timeline, and it starts with a report to the district council.

• June 2025: concerns about activity on the land are first reported to Cherwell District Council, which suspects unauthorised engineering works
• Early July 2025: the Environment Agency receives a separate report from a member of the public about waste being deposited near the River Cherwell and the A34
• Early July 2025: a joint visit by all three authorities finds mechanically treated waste in quantity, confirming a large-scale illegal operation rather than fly-tipping
• 17 and 29 July, 4 August 2025: the county council serves three Planning Contravention Notices to establish who owns the land
• 31 July 2025: the Environment Agency serves a cease-and-desist letter
• 23 October 2025: a court grants a Restriction Order under section 109D of the Environment Act 1995, banning access and any further tipping. Breaching it is a criminal offence, so police can arrest on the spot
• 11 December 2025: the government confirms the Environment Agency will pay for clearance, exceptionally
• 19 January 2026: the contract is awarded
• 2 March 2026: the contractor mobilises, after flooding in January and February slowed the start
• 14 April 2026: lorries begin removing waste
• 27 August 2026: clearance declared complete

Finding the owner was the hard part. The notices revealed the land “had been sold multiple times in a short period, with Land Registry records not reflecting up-to-date ownership”, which the report calls consistent with tactics used to frustrate formal action. At the time it was written, the Land Registry title had caught up only with the second of three transactions.

The footpath is still closed

The clearance is finished. Public access is not restored.

A public footpath crosses the site, and the county council closed it by order during the response, along with the neighbouring A34 lay-by. The Environment Agency says a Public Rights of Way officer from the county council has visited the site to make recommendations for the footpath’s eventual reopening. Neither authority has published a reopening date.

National Highways is inspecting its drainage channels along the northern and eastern boundaries, and advising on tree safety work where roots run into the waste site.

The jumbo sandbag wall built to stop waste reaching the River Cherwell has been taken away, and the bags’ contents are being cleaned for re-use. The agency sampled the river every two weeks from late November 2025, and reported chemical levels similar to other English rivers and too low to expect harm.

Kidlington is still on the national watchlist

The Environment Agency publishes a monthly watchlist of high priority waste sites in England. It was last updated on 28 August, the day after the clearance was announced, and it still carries a Kidlington entry: reference 60, “shredded mixed waste”, 8,000 tonnes.

That entry has not changed since the list was first published on 22 May. The agency says it is “restricted in the level of detail it can publish” because it cannot prejudice ongoing enquiries. It aims to release site-specific information on its Waste Hub by the end of September 2026. Until then the list does not say whether a site has been dealt with.

Two other Oxfordshire entries sit on the same list: Denchworth, near Wantage, at 4,000 tonnes of commercial waste, and an Oxford site at 500 tonnes of construction and demolition waste. Neither is in Cherwell district.

Nobody was obliged to clean it up

This is the part that tends to surprise people. No public body has a legal duty to remove illegally dumped waste, and none is funded to do it. The Environment Agency said so plainly in December: it “is not legally responsible for clearing illegal waste, and is not funded to do so”, and it still holds that the criminals should pay.

What changed the decision was fire. Fire and rescue advice indicated a blaze on site was possible, which could have closed the A34, hit air quality across the area and interrupted electricity supplies. The agency called that risk “wholly exceptional” and said it would fund the clearance by making efficiencies elsewhere in its operations, without scaling back other services.

Cherwell’s leader, Councillor Lesley McLean, welcomed the completion on 27 August. Residents “have had to live with the impact of this appalling environmental crime for far too long”, she said. She added that it “is equally important that those responsible are held to account”.

What it means for you

• The footpath across the site is still shut. There is no published reopening date. Do not plan a walk through it.
• The gate is locked and the entrance blocked. Access to the land remains restricted while the investigation continues.
• If you know anything about the dumping, the Environment Agency’s 24-hour hotline is 0800 807060, or report anonymously to Crimestoppers on 0800 555111.
• To report odour or mud on the road connected to the site, the agency asks you to use the postcode OX5 2JJ and begin your description with “Kidlington Illegal Waste Site”.
• Suspect illegal waste activity elsewhere in Oxfordshire? The county council takes reports of unauthorised waste developments at Tellplanning@Oxfordshire.gov.uk.
• Before you hand rubbish to anyone, check they are a registered waste carrier on the Environment Agency’s public register. If a firm is not listed, it is not legal, and you can be held responsible for where your waste ends up.
• Fines for dumping waste illegally or failing to treat it correctly are rising to a maximum of £5,000, up from £300.
