Sutton Council has approved a revised restoration plan for Beddington Farmlands, marking a significant step towards transforming the former landfill site into a publicly accessible nature reserve.
The Housing, Economy and Business Committee received an update on Tuesday, September 15, 2026, detailing the revised plan which replaces ecologically unviable acid grasslands with species-rich lowland meadows. This new approach also includes a sustainable water supply for lakes and mandates phased delivery by 2029, with a commitment to long-term monitoring and a biodiversity net gain of over 30%.
Simon Shellcraft, Planning Enforcement Manager, and David Warburton, Senior Biodiversity Officer, presented the revised plan, highlighting that the planning committee had resolved to grant planning permission on September 2. This permission is considered a substantial improvement on the previously consented but undelivered scheme.
The site, an 88.4-hectare former landfill, has a complex history of mineral extraction and landfill use. The original restoration plan, approved in 1995 and updated in 2014, included acid grasslands which proved to be ecologically unviable and environmentally risky. The original plan for acid grasslands proved 'ecologically unviable' and 'environmentally risky' due to forcing an acidic habitat once the alkaline soil proved technically unviable and environmentally risky as well
. Additionally, Thames Water had objections regarding the potential acidification of watercourses and the alkaline soils on site made the delivery of acid grassland unviable.
Councillor Tom Foster, Chair of the Conservation Access Management Committee (CMC), expressed his commitment to scrutinising the process and ensuring the restoration's completion. Officers explained that the conditions have been agreed by the Planning Committee, and the Section 106 agreement is being progressed. The CMC will play a key role in reviewing the details of these conditions, including access arrangements and habitat creation.
David Warburton elaborated on the ecological benefits of the new lowland meadow, stating it will attract ground-nesting birds like skylarks and is rated highly in biodiversity metrics, even surpassing acid grasslands. The new planning application provides enhanced powers for enforcement and monitoring. These enhanced powers include greater powers to enforce that and and more importantly monitor what they're doing as far as we're aware there's very little in the way of records that they hold as to what they've actually done how they've gone about doing the restoration so in this new scenario we have regular monitoring for them they signed off by a suitable qualified ecologist to say this is what's happened on this parcel of land and then it's monitored on a regular basis going forward

Concerns regarding wildfire risks were addressed, with the inclusion of an additional fire hydrant recommended by the fire brigade and management of grassland to prevent thatch build-up. The revised scheme also includes an upgraded access strategy for safe vehicle and pedestrian access, balancing public enjoyment with wildlife protection, and a new 900-square-meter agricultural building for conservation grazing and equipment storage. The new agricultural building is designed to support the long-term management of the nature reserve, directly improving livestock welfare for the cattle grazing required to manage the habitats
. The meeting also mentioned that three cattle introduced into Phase 1 wet grassland in early March 2026 to create short grassland conditions for target species
.
The long-term ownership and management of the site are to be determined through the Section 106 agreement, with potential for a fund to be established for the council or conservation organisations to manage the site in perpetuity. The biodiversity net gain aspect includes a minimum of 30 years of monitoring. The Section 106 agreement will be crucial in determining future arrangements, potentially involving a fund for the council or conservation organisations to manage the site in perpetuity. Furthermore, the Section 106 agreement will include financial consequences for missed milestones, such as a cash collateral trust. This trust, with a minimum sum of £2.34 million, can be drawn down to carry out works in default if milestones are not met.
Valencia Waste Management, the current operators, have indicated that the certainty provided by the revised permission will allow them to allocate more resources towards the restoration, potentially leading to faster, phased public access to the land. Valencia Waste Management (VWM) has stated that they will be able to utilise the certainty of this revised permission to release greater resources towards the site's restoration and bring about a faster, phased delivery of public access to the land
. The access strategy is an outline plan, and detailed proposals will be developed to ensure a staged approach to habituating wildlife to human presence. Factors influencing this include balancing public enjoyment with wildlife protection and ensuring safe vehicle and pedestrian access.
The costs of the restoration of Beddington Farmlands will be met by Valencia Waste Management (VWM). The Council's officers involved in advice and monitoring are funded within existing resources.
