Do I need planning permission for a solar panels in Westminster City Council?
Typical answer
In most cases, solar panels in Westminster City Council fall under Permitted Development rights (Part 14 Class A), but require Prior Approval from the Local Planning Authority before works start. Key factors include Article 4 restrictions, conservation-area designation, and compliance with the specific thresholds set out in the General Permitted Development Order 2015 — check these carefully before proceeding.
