UK landmark renewable-energy project gets underway in Sutton

Residents at a flagship new housing development will be able to heat their homes and water using sustainable low-carbon energy following a major agreement reached between Sutton Council and Barratt Developments Plc.  

The Sutton Decentralised Energy Network (SDEN) will provide energy to the joint David Wilson Homes and Barratt London (both part of Barratt Developments Plc) development of 725 one and two bedroom apartments, and three and four bedroom homes at New Mill Quarter in Hackbridge.

SDEN will capture heat directly from the Energy Recovery Facility (ERF) at  Beddington  which will then be transported in highly insulated pipes to provide low-carbon heat and hot water to local homes and businesses. In the first phase connecting to the Barratt’s development it is projected to save 900 tonnes of CO² emissions each year, with future phases expected to save over 5,000 tonnes.


Sutton Council, as part of its One Planet Sutton pledge to reduce the borough’s environmental footprint, is unique in the UK by delivering its own decentralised energy network. This Investment will reduce the borough’s carbon emissions and dependency on fossil fuels. It also supports the policies of both government and the Greater London Authority to reduce carbon emissions and the environmental footprint.

Homes at New Mill Quarter are due to use SDEN from as early as summer 2017. Backup gas boilers situated on the New Mill Quarter site will be used initially until summer 2018, then heat from the existing landfill gas engines in Beddington will be used until the ERF becomes operational. In addition to the new homes, the development will include shops, a doctors’ surgery, a supermarket and an assisted-living care home. The development also includes eco-friendly living walls making it a highly sustainable, as well as desirable, place to live and work.

Cllr Jayne McCoy, Chair of the Housing, Economy and Business committee, said: “Here in Sutton we are determined to champion a sustainable future. Not only have we ensured delivery of a decentralised energy network through our own investment, we are capturing an energy source that would otherwise be wasted, when other UK decentralised energy schemes still rely on fossil fuels  to generate the initial heat.”

Mark Bailey, Regional Director of Barratt David Wilson Homes Southern, said: “We are delighted to announce this innovative agreement between Sutton Council and Barratt Developments. It will be a landmark project for the UK and the first decentralised heating network of its kind to combine so many different end users into a single sustainable heat supply network.  We are confident it will be a great success for both organisations and we look forward to continuing to work with the Council to deliver the scheme, providing real benefits for  future residents and helping to reduce our overall impact on the planet.”
