Who are we?

Sutton Decentralised Energy Network Limited (SDEN) is wholly owned by the London Borough of Sutton. We are a sustainable energy supplier that provides low-carbon energy to homes and businesses in Sutton, and in future across the whole of South London.

Why use a Decentalised Energy Network?

Rather than each home having its own boiler, every house and flat on the decentralised energy network receives hot water directly from the new energy recovery facility for heating and hot water use. This maximises efficiency and significantly reduces the need for fossil fuels.

Most other decentralised energy networks across the UK use fossil fuels in high-efficiency energy generation plants to generate heat. We are different because we generate low carbon heat from other energy sources.
