Beddington Farmlands restoration plan set to boost biodiversity
A revised restoration plan for Beddington Farmlands has been approved, promising a significant boost to local biodiversity and transforming the former landfill site into a publicly accessible nature reserve.
The Housing, Economy and Business Committee of Sutton Council heard on Tuesday 15 September 2026 that the new plan replaces ecologically unviable acid grasslands with species-rich lowland meadow, a sustainable water supply for lakes, and mandates phased delivery by 2029. This revised approach is expected to deliver a biodiversity net gain of over 30%.
Simon Shellcraft, Planning Enforcement Manager, and David Warburton, Senior Biodiversity Officer, presented the updated plan, which was approved by the planning committee on 2 September, subject to a new Section 106 agreement. This new permission is considered a significant improvement on the previously consented but undelivered scheme.
The site, an 88.4-hectare former landfill, has a history of mineral extraction and landfill use. The previous restoration plan, approved in 1995 and updated in 2014, included acid grasslands which proved to be technically unviable and environmentally risky due to the site's alkaline soils. The new plan replaces this with species-rich lowland meadow, which is rated highly in biodiversity metrics and is considered a betterment in terms of biodiversity net gain. This new habitat is expected to attract ground-nesting birds such as skylarks, as well as priority species like lapwing and little ringed plover.
The upgraded access strategy includes improved pedestrian and cycle facilities, new access gates, and new seating areas. It establishes a clear network of routes, including a year-round shared path and specific permissive loops. The strategy aims to balance public enjoyment with wildlife protection by habituating wildlife to human presence through a staged approach and implementing strict controls on activities, such as barbecues. The detailed proposals will be developed to ensure a staged approach to habituating wildlife to human presence.
Councillor Tom Foster, Chair of the Conservation Access Management Committee (CMC), expressed his desire to scrutinise the process and ensure the restoration is completed. Officers explained that the conditions have been agreed by the Planning Committee, and the Section 106 agreement is being progressed. The details of the conditions will be determined by planning officers in conjunction with the CMC and other stakeholders, providing an enforceable framework.
The new plan mandates phased delivery by 2029. The revised application ensures there is no single end date for completion of the restoration work, but a suite of bespoke conditions and obligations to ensure that each element is completed to a strict timescale and to a high standard. Monitoring reports will be signed off by a suitably qualified ecologist to confirm what has happened on a parcel of land, and this will be monitored on a regular basis. The monitoring will be independently assessed by a suitable bi-ecologist, utilising the DEFRA condition assessment metric.
Concerns regarding wildfire risk were addressed with the inclusion of Condition 25 of the hydrological survey and Condition 11 for an additional fire hydrant, as recommended by the fire brigade.
The Section 106 agreement is crucial in determining future arrangements for long-term ownership and management. It may involve a fund for the council or conservation organisations to manage the site in perpetuity. The biodiversity net gain aspect has a minimum of 30 years of monitoring. The agreement will also include financial consequences, such as a cash collateral trust, to incentivize the applicant to meet milestones. 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. The costs of the restoration of Beddington Farmlands will be met by Valencia Waste Management (VWM). Council Officers involved in the advice/monitoring of the works are funded within existing resources and do not present a financial pressure. The revised scheme uses an updated and fully costed Cash Collateral Trust as part of the new section 106 agreement, with a minimum sum of £2.34 million.
The new planning application provides greater powers to enforce delivery and monitor progress. The Council served a Breach of Condition Notice on Valencia on 5 September 2025, which remains extant until the legal agreement for the revised application is signed and the decision notice for the planning permission is formally granted. Any future enforcement action (if necessary) would be under the umbrella of the revised scheme.
The meeting concluded with the Chair thanking the team for their perseverance, expressing confidence that the Beddington Farmlands nature reserve will be a significant asset for the borough.
