The Environment Agency has made two further arrests in its investigation into large-scale illegal waste dumping at Kidlington in Oxfordshire, taking the total number of arrests connected with the site to six. The arrests come less than two weeks after the regulator confirmed that 22,105 tonnes of commercial and household waste had been removed from the site. The investigation remains ongoing and the two men arrested on 8 September have been released on conditional bail pending further enquiries.
According to the Environment Agency's 8 September update, a 21-year-old man from Ashford in Surrey and a 43-year-old man from Stanwell in Surrey were arrested with support from Surrey Police and the South East Regional Organised Crime Unit. The agency's National Environmental Crime Unit is leading the investigation.

Kidlington Site Has Now Been Cleared
Environment Agency officers first attended the Kidlington site on 2 July 2025 following reports of waste being tipped. A cease-and-desist letter was subsequently issued, but officers became aware of further activity in October. A court order closing the site was granted on 23 October 2025. The Environment Agency says no further tipping has taken place there since that order was made.
The regulator announced on 27 August that the Kidlington clean-up had been completed. An estimated 22,105 tonnes of material was excavated and removed, including tyres, shredded plastic and household rubbish. Concrete blocks were also installed at the entrance and the main gate secured. The six arrests comprise one made in November 2025, two in January 2026, one in February and the two announced on 8 September. The latest Government announcement does not report charges, convictions or findings of guilt against the individuals arrested.
Why the Enforcement Push Matters to Construction
The Kidlington material is described by the Environment Agency as commercial and household waste rather than specifically construction and demolition waste. The construction relevance lies in the wider enforcement regime now being applied to waste producers, carriers, brokers and disposal sites. Under the statutory waste duty of care code, businesses producing or controlling waste must take reasonable steps to ensure it is transferred to authorised operators and handled correctly. The code expressly covers construction and demolition waste.
For contractors, demolition specialists and groundworkers, appointing a waste subcontractor does not make the compliance trail irrelevant. Waste carriers should be appropriately registered, destination facilities must be authorised to receive the material and the waste itself has to be accurately described. The Environment Agency has separately reminded the construction sector that responsibility runs from the business generating the waste through to its final destination. That is the other side of the construction waste market explored in LCM's analysis of how London contractors are turning site waste into recoverable value. Reuse and material recovery can reduce disposal volumes, but material that does leave a project still needs an auditable and lawful route through the waste chain.
Government Expands Waste Crime Crackdown
Kidlington is now part of a wider government campaign against organised waste crime. The Waste Crime Action Plan sets out increased enforcement, earlier intervention and clearance of some high-risk illegal waste sites. The Government has also identified sites including Bolton House Road in Wigan and Midland Road in Bradford for intervention, while the Environment Agency is increasing intelligence-led enforcement and publishing information on waste-crime hotspots.
For the demolition and refurbishment sector, waste control also begins before material reaches a lorry. LCM has previously examined how more complex demolition and cut-and-carve projects change site sequencing and waste streams, particularly where old structures contain mixed materials, contamination or hazardous substances. The wider shift towards recovery rather than disposal is already visible in London. Earlier this year, LCM reported on the Circular Construction Hub launched in the Royal Docks, designed to recover and reuse materials that might otherwise enter conventional waste streams.
Investigation Continues
Environment Agency Area Manager Colin Chiverton said the latest arrests were part of continuing efforts to gather evidence following the clean-up of the Kidlington site. The physical clearance is complete, but the enforcement case is not. The next publicly confirmed stage is the continuation of the National Environmental Crime Unit investigation; no charging decision or court timetable for the two men arrested on 8 September has been announced.
