EN3 — Decentralised energy.
How Lambeth actually applies EN3: who leans on it, where it bites hardest, and how often it's invoked. The policy text is the rule; this is the behaviour.
EN3 is a published Lambeth planning policy. This page records where it appears in the council's published planning decisions.
Cited under: Lambeth Local Plan (adopted)
Policy EN3 requires major developments to connect to existing decentralised heating networks, unless a feasibility assessment shows it's not possible. Minor developments should be designed to connect if reasonably possible. Developments without existing networks should connect to planned future networks, following London Plan policies SI3 and SI4 if immediate connection is not possible.
