SM2 primarily covers Sutton / Belmont in Sutton.
Decisions for SM2 are made by Sutton Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Sutton: No.
Building regs from £950. We do not charge hourly. Free site survey across all SM2 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Sutton Council timelines align with the national norm.
Sutton / Belmont in SM2 is characterised by the housing stock of Sutton — broadly 1930s semi-detached dominates.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SM2 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SM2 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SM2 | Sutton / Belmont | Georgian villas, 1930s semi-detached | SM2 covers Sutton / Belmont only; Sutton Council handles the drawing package. |
| SM2 | Cheam | Georgian villas, 1930s semi-detached | Cheam sits inside SM2; drawing package proposals here are determined by Sutton Council. |
| SM2 | Belmont | 1930s semi-detached | Belmont sits inside SM2; drawing package proposals here are determined by Sutton Council. |
| KT4 | Worcester Park | 1930s semi-detached | Adjoining district to SM2, also inside Sutton for drawing package purposes. |
| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | Adjoining district to SM2, also inside Sutton for drawing package purposes. |
| SM3 | Cheam / North Cheam | Georgian villas, 1930s semi-detached | Adjoining district to SM2, also inside Sutton for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few SM2 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering SM2 (Sutton / Belmont): Sutton Council runs 17, and Beddington Park, Cheam Village, Sutton Central are the ones SM2 (Sutton / Belmont) owners meet most. A drawing package inside a SM2 (Sutton / Belmont) conservation area loses permitted development, so the SM2 (Sutton / Belmont) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Carshalton Village a drawing package is judged on the street elevation first.
SM2 (Sutton / Belmont) permitted development status: there is no borough-wide direction from Sutton Council, so a drawing package at a SM2 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a SM2 (Sutton / Belmont) sale to argue it later.
The building fabric around SM2 (Sutton / Belmont): 1930s semi-detached dominates; Edwardian terraces and villas in Sutton central; Victorian cottages in Carshalton; post-war in Hackbridge. Outer south London suburban; generally permissive; Carshalton and Cheam conservation areas add heritage in pockets. A drawing package in SM2 (Sutton / Belmont) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Sutton Council.
