Eastleigh

MP: Liz Jarvis (Liberal Democrat) England Data to July 2026

Eastleigh has 29 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 10,000 homes. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £3.6m across the constituency's 38,852 homes.

Ranks 175 of 650 for clean power approved and not built.
