The huge site at Kidlington, Oxfordshire, housed an estimated 22,000 tonnes of waste accumulated in 2025

One of England’s biggest illegal waste sites has finally been cleared, only after an operation that left taxpayers facing a supersized bill of around £6million.

The huge site at Kidlington, Oxfordshire, was cleared after an estimated 22,000 tonnes of household and commercial waste accumulated in 2025.

Located between the River Cherwell and the A34, the damning site was among some 30 large-scale illegal dumping grounds identified during a BBC investigation.

The Government says it intends to recover the cost of dealing with the site from those behind the illegal operation, with ministers promising tougher measures against waste crime, including efforts to confiscate offenders’ cash, property and other assets.

New figures show efforts to recover money from convicted waste criminals have so far generated £7.3m over the past five years.

The Environment Agency issued 66 confiscation orders under the Proceeds of Crime Act between January 2021 and March 2026 - of which, 14 have not yet been settled completely, leaving some £1.4m outstanding.

The figures apply to major waste crimes dealt with by the Environment Agency, and do not cover smaller-scale fly-tipping cases, which are generally handled by local councils.

Campaigners say the sums recovered are tiny compared with the financial damage caused by illegal waste dumping.

The Environment Agency estimates waste crime to cost the UK economy around £1bn every year.

Baroness Sheehan, chair of the House of Lords Environment and Climate Change Committee, said stronger enforcement was needed.

She said the figures pointed to a failure to deliver “consistent, decisive enforcement”, and warned that communities and taxpayers were continuing to bear the financial burden.

“With clean-up costs at sites such as Kidlington far exceeding these sums, and enforcement still lagging, the taxpayer continues to foot the bill,” she said.

The Environment Agency has also undertaken work at another major illegal dumping site at Hoads Wood, close to Ashford in Kent.

The combined cost of clearing the two locations has been budgeted at £20m, although the Kidlington operation was completed below its initial £7.3m contract value.

Under the Government’s Waste Crime Action Plan, the Environment Agency can take responsibility for clearing illegal sites in exceptional circumstances, particularly where waste poses a serious threat to people or the environment.

Harrowingly, landowners are normally expected to meet the cost when criminals use their property for illegal dumping.

Six more major sites have been identified for potential clearance using public money, including locations in Kent, Surrey, West Yorkshire, Lancashire, South Yorkshire and Greater Manchester.

Environment Secretary Dame Angela Eagle said the Government was determined to tackle organised waste crime, promising more officers and greater use of technology, such as drones.

The Environment Agency said some confiscation orders were still within the six-month period allowed for payment, and that additional assets could be seized if information about offenders’ finances comes to light.

Four men were arrested over the Kidlington waste site, with all having been bailed while the investigation remains ongoing.
