Sutton Decentralised Energy Network Limited (SDEN) is a company wholly owned by  the London Borough of Sutton. Set up in 2016, SDEN will deliver heating and hot water to residents and businesses across South London, starting in Sutton. SDEN will reduce fossil fuel use, contributing towards Sutton’s goal of becoming a zero carbon borough by 2025.

Our Energy Sources

The Sutton Decentralised Energy Network (SDEN) will use energy generated by the new Energy Recovery Facility (ERF) and the existing landfill gas engines in Beddington. This will provide low-carbon energy in the form of hot water, meeting the heating and hot water needs of homes and businesses in Sutton and neighbouring boroughs.

Our Vision

We are pleased to introduce SDEN, a truly ground-breaking initiative that will ultimately deliver low carbon supplies of hot water for heating and domestic hot water uses across South London.

Our ambition is to utilise local sources of heat to become a key supplier of low carbon heating in South London.

SDEN will significantly reduce fossil fuel use, contributing towards our goal of lowering our carbon emissions.

We are already working on Phase 1 of our network which will supply heat to around 725 homes, a care home and a supermarket at the new New Mill Quarter (formerly Felnex) development.

Next we will look to expand the network across South London. We want to work with you to tap into this sustainable, low carbon supply.
