Every Merton postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. Merton fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| SW19 | Wimbledon / Colliers Wood | Victorian villas, Edwardian terraces | A building regulations package in Wimbledon / Colliers Wood may land with Merton Council or Wandsworth Council — SW19 crosses the boundary, and the SW19 policies map decides it street by street. |
| SW20 | Raynes Park | Victorian villas, Edwardian terraces | SW20 covers Raynes Park only; Merton Council handles the building regulations package, and Raynes Park case officers apply the SW20 conservation-area map. |
| SM4 | Morden | 1930s semi-detached, post-war flats | SM4 covers Morden only; Merton Council handles the building regulations package, and Morden case officers apply the SM4 conservation-area map. |
| CR4 | Mitcham | 1930s semi-detached, post-war estates | CR4 covers Mitcham only; Merton Council handles the building regulations package, and Mitcham case officers apply the CR4 conservation-area map. |
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | SW16 straddles a boundary: Streatham / Norbury addresses fall to Lambeth Council or Wandsworth Council or Merton Council or Croydon Council, so confirm which authority validates the building regulations package before submitting SW16 drawings. |
| SW17 | Tooting / Earlsfield | Edwardian terraces | Tooting / Earlsfield is split at SW17. Either Wandsworth Council or Merton Council can determine a building regulations package here, so the SW17 address is checked against both policies maps first. |
Roof pitch, wall build-up and plot depth change every few Merton streets, and each one changes what a building regulations package can achieve at that address.
How designation changes a Merton building regulations package: Merton Council maintains 28 conservation areas, including Mitcham Cricket Green, Wimbledon Common, Wimbledon Village. Inside any of them a Merton building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Wimbledon Common sets the tone for Merton casework.
Article 4 and your Merton building regulations package: Merton Council has made no borough-wide direction, so permitted development for a building regulations package in Merton generally survives outside Merton conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SW19 owner records that a building regulations package was lawful.
Merton housing stock: Victorian villas in Wimbledon; Edwardian terraces in Tooting and Colliers Wood; 1930s semi-detached in Morden and Raynes Park; post-war flats in Mitcham. Wimbledon is heavily conservation-controlled; outer Merton (Morden, Mitcham) is permissive. Read that before choosing a building regulations package route in Merton — construction, not postcode, sets what is achievable. Merton Council charges £548 for a householder application and has 8 weeks to determine it.

Direct answers to the questions Merton homeowners ask every week about building regulations drawings.
Start a free quote →In Merton, you can submit building regulations applications to either Merton Council's in-house Building Control (LABC route) or to a private approved inspector. Both routes produce the same legally-valid completion certificate. We submit to whichever suits your project and builder.
The building regulations fee for a Merton project is set by scope: a straightforward extension or loft is the baseline, while HMOs, basement conversions and flat splits need more detailing and coordination. Structural calculations are priced by the intervention — a single beam is far less than a full loft or underpinning package. See our fees.
Yes — every habitable loft conversion in Merton (and across England) requires Building Regulations approval covering fire escape, floor structure, insulation and staircase. This is independent of whether you also need planning permission.
Part L of the Building Regulations sets minimum energy-efficiency standards — insulation, glazing U-values, air permeability, heating efficiency. New extensions in Merton must meet the 2025 uplift (Future Homes Standard transition). We include full Part L calculations and a compliance statement in every Complete package.
Once submitted, Merton Council Building Control reviews Full Plans within 5–8 weeks. Approved inspectors typically review in 2–4 weeks. On-site inspections run through the build — typically 6–10 visits depending on scope.
In Merton, building regulations are required for: loft conversions, extensions, structural alterations, roof replacements, new openings in walls, and any work to a flat. Some minor works (like-for-like replacements, small porches) are exempt. We confirm at the free site visit.
A completion certificate from Merton Council Building Control (or an approved inspector) confirms your works comply with Building Regulations. It is essential for selling or re-mortgaging — lenders and conveyancers require it. We manage the inspection sequence and close out sign-off as part of every Complete package.
Extensions and loft conversions in Merton that change the building's energy characteristics require an updated EPC (or SAP/SBEM calculation as part of Part L compliance). We include Part L calculations in every Complete and Bespoke package.
