Planning and conservation in Merton
Planning and building control in this area are handled by Merton Council (London Borough of Merton). Conservation areas are concentrated around Wimbledon; flood risk can apply near the Wandle. Before you design, check whether your property is in a conservation area, is listed or is covered by an Article 4 direction; these change what you can build without permission. Our guide to permitted development in London explains the national rules, and loft conversion regulations covers roof works.
Wimbledon conservation streets usually need careful roof and front-elevation design; outer Merton is more suburban.
Typical building costs in Merton
Costs in Merton usually sit between outer London rates (about £2,500 to £3,500 per m²) and central London rates (about £3,500 to £4,500+ per m²), depending on the street, access and specification. Budget on top for professional fees (about 15%), consents and contingency (8–15%) and VAT at 20% on extensions and renovations. These are indicative industry ranges for 2026, not a quote; see our London cost guide or request fixed quotes from local builders.

Questions about building in Merton
Can I request quotes from builders in Merton?
Yes. Quote requests are accepted from anywhere in Merton, including Wimbledon, Mitcham, Morden, Raynes Park, Colliers Wood, South Wimbledon, across London and the wider UK. With your consent, we pass your enquiry to up to 3 local builders who advertise with us.
Do I need planning permission for an extension in Merton?
It depends on your property. Houses outside conservation areas may be able to use permitted development, while flats, conservation areas and Article 4 directions usually mean an application to Merton Council (London Borough of Merton). A Lawful Development Certificate gives certainty.
Should I check a builder’s insurance?
We ask every builder who advertises with us to provide proof of current public liability insurance before they are listed. Always check each builder’s insurance, references, written quote and trade body membership yourself before work starts.
