The revised plan sets no single completion date. Each phase gets its own deadline, and the 2025 breach notice stays live until the legal agreement is signed.

Sutton’s planning committee agreed on 2 September to grant permission for a revised restoration plan at Beddington Farmlands. A report going to a different committee next week sets out what that decision fixes, and what it leaves open.

The headline change is that there is no longer a single date by which the whole site must be restored.

The report puts it plainly. The revised application “ensures there is no single end date for completion of the restoration work, but a suite of bespoke conditions/obligations to ensure that each element is completed to a strict timescale and to a high standard”. That is from the council’s own Beddington Farmlands Update, dated 15 September 2026.

The old deadline was December 2023. It came and went with the site unrestored.

The enforcement notice is still live

The council served a breach of condition notice on the site’s owners, Valencia Waste Management, on 5 September 2025. That notice is now a year old.

The report confirms it remains extant, and says it will stay that way “until the legal agreement for the revised application is signed and the decision notice for the planning permission is formally granted”. Any enforcement after that would be under the new permission rather than the old one.

The section 106 agreement is the outstanding piece. The report calls it complex, says specialist legal advice has added to the delay, and notes that further counsel advice has been sought on the drafting.

One thing that agreement will carry is a replacement for the old financial guarantee. The 2013 bond becomes what the report calls “an updated and fully costed Cash Collateral Trust”. Its purpose is to let the council call in the money and finish the ecological restoration itself if the operator materially breaches its obligations or becomes insolvent.

Why the acid grassland went

The plan councillors approved on 2 September drops 12.6 hectares of promised acid grassland and lowland heath and puts species-rich meadow in its place. We covered that application before the committee met, when 61 of the 65 comments received were objections.

The report is blunter than the officer report was about why. It says delivering acid grassland “was found to be un-deliverable, largely due to the site’s alkaline soils and Thames Water’s own objections regarding the potential acidification of watercourses”.

The wetlands were the other sticking point. The 2024 application proposed unlined ponds fed with treated water from the nearby Thames Water works. The Environment Agency objected, because water of that quality could reach the drinking water aquifer beneath the site. Valencia went back to lining the ponds with an impermeable membrane. The Environment Agency formally withdrew its objection in October 2025, which is what allowed the application to reach committee.

What has actually happened on the ground

The report lists progress over the past nine to twelve months, taken from the site’s conservation science and access management meetings:

  • Phase 10 earthworks: the Environment Agency approved the filling of Lagoon 4, and the southern half of Phase 10 has been filled and profiled, about half the phase
  • Bird habitat: the North Lake islands have been substantially cleared to create bare ground for lapwing and little ringed plover
  • Grazing: three cattle went into the Phase 1 wet grassland in early March 2026 and have since moved to Phase 3
  • Invasive species: clearance of Himalayan balsam from the Southern Channel started in mid-February 2026, with repeated flailing since, and goat’s-rue on the mound was spot-sprayed in spring
  • Reedbeds: Valencia has approved the funding, a specialist contractor has been appointed to move reed clumps with trucksaws, and works were expected to start in early September 2026
  • Staffing: Thames Water has put a full-time project manager on the site, and Valencia has moved staff from the weighbridge onto site management

The council has also repaired stretches of the southern boundary fence, with talks continuing about securing the perimeter near the 100 Acre gate.

Access is improving, slowly

Beddington Farmlands is not going to be a public park. The report is explicit that it is a managed nature reserve, on an active landfill, with health and safety limits on who goes where.

Within that, the approved application secures:

  • new pedestrian and cycle facilities
  • access gates and seating areas
  • a new east-west route across the site
  • an upgraded western permissive path to the bird hides
  • the removal of the dead-end path along the Beddington Park fence

The council also reports a “highly successful” Beddington Big Day, which took 97 people onto the site across six guided tours led by Valencia, council officers and the Beddington Farmlands Bird Group. Work is under way on a lone worker system so bird group volunteers are not held back by the current buddy requirement, which the report says has cut the amount of bird recording being done.

What it means for you

For residents of Beddington, Hackbridge and Wallington, the practical answer is that the site will open up in phases rather than on one date. The council has swapped a single deadline it could not enforce for a set of phase deadlines it says it can.

Whether that works is the open question, and the report says so itself. Under legal risks it warns that failing to act on continuing breaches “could mean the restoration is unlikely to go ahead”, cause reputational harm to the council and undermine its future options.

The Housing, Economy and Business Committee takes the report at 7pm on Tuesday 15 September at the Civic Offices on St Nicholas Way. The agenda and papers are published, and the committee is asked only to note the position rather than decide anything.
