Southwark heat network zone

Southwark's heat network is built around SELCHP, the energy-from-waste plant on the Lewisham border, whose network serves about 17,000 properties according to the February 2025 report. The council and Veolia are extending it, and a heat supply agreement notice was published in January 2026. We have found no zone partner procurement.

10 possible zones, four strategic: Thames Southbank, SELCHP, Camberwell, and Elephant and Castle.

Candidate areas come from government-commissioned studies and council work. They are not legal boundaries. A zone’s boundary is fixed only when it is designated under the zoning regulations.

We have found no appointed or bidding developer for Southwark.

No statutory zone developer can be appointed until a zone is designated. Partners appointed by councils before then are listed as development or delivery partners.
