Planning in Westminster
Local planning rules for kitchen renovations in Westminster.
Westminster contains 56 conservation areas covering virtually all residential stock — Mayfair, Belgravia, Bayswater, Marylebone, Pimlico, Soho, St John's Wood, Maida Vale and Fitzrovia among them. Thousands of properties are statutorily listed (Grade I, II* or II). PD rights are removed under Article 4 across most of the borough. The City Plan and individual Conservation Area Audits govern alterations. Basement extensions are heavily regulated under the Basement SPG (single-storey only on most plots, no extensions under gardens beyond 50% footprint). Mansard roof extensions are typically the preferred upward route over rear dormers. Pre-application consultation is essential — Westminster's planning officers operate a structured pre-app service and outright refusals without engagement are common. Listed Building Consent applications run in parallel with planning and require specialist conservation input.
Our planning team handles the full submission for Westminster addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your kitchen renovation is permitted development, prior approval, or full planning before you sign anything.

Do I need planning permission for a kitchen renovation in Westminster?
+
Planning rules vary across Westminster. We check permitted development eligibility, conservation area status and any Article 4 directions affecting your specific postcode before quoting.
