Which Sutton postcodes does this conservation area application service cover?
Every Sutton district on our books, the era of housing behind it, and which office will be validating your drawings. Government sets the charge in the final column for 2026; what we charge to draw is separate and agreed up front.
| Postcode | Area | Dominant stock | What it means for a conservation area application |
|---|
| KT4 | Worcester Park | 1930s semi-detached | KT4 is Worcester Park and nothing besides, wholly inside Sutton, so the borough's officers determine the application against the KT4 conservation area mapping. |
| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | SM1 covers Sutton town itself. Applications here are handled by the borough, with Sutton Central the designation that most often reshapes a scheme. |
| SM2 | Sutton / Belmont | Georgian villas, 1930s semi-detached | SM2 takes in Belmont and the southern part of Sutton, again undivided, so no boundary question arises before submission. |
| SM3 | Cheam / North Cheam | Georgian villas, 1930s semi-detached | Cheam and North Cheam fall entirely within SM3, which keeps validation simple: one council, one Local Plan, and Cheam Village the designation most likely to be in play. |
| SM5 | Carshalton | Victorian terraces, Georgian villas | SM5 is Carshalton, where the Village designation covers the oldest part of the district. The cottage stock inside it carries noticeably tighter expectations than the streets immediately around it. |
| SM6 | Wallington / Hackbridge | Edwardian villas, 1930s semi-detached | Wallington and Hackbridge share SM6 and sit inside Sutton throughout, so a single validation checklist applies right across the district. |
| SM7 | Banstead | Interwar semis dominate: 30.6% of Sutton's 86,290 dwellings date from the 1930s on the VOA's March 2025 count. Edwardian terraces and villas sit around Sutton centre, Victorian cottages in Carshalton, post-war housing at Hackbridge. | Conservation areas are designated by the authority that owns them, so naming the authority has to come first. Sutton designates and maps the areas inside the London borough. Banstead's are not among them: SM7 is in Surrey, where Reigate and Banstead Borough Council makes the designations and publishes the appraisals, and a Sutton conservation area map will not show a Banstead street at all. |
Which Sutton neighbourhoods suit a conservation area application best?
From the Carshalton cottages to the post-war streets at Hackbridge, pitch, wall construction and plot depth all move about, and each of them shifts what a designated address can actually carry.
- Sutton (SM1) — conservation area application work in Sutton means edwardian terraces, 1930s semi-detached. Sutton is Edwardian centre, 1930s residential. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed throughout SM1. Sutton Council decides the Sutton application, and Sutton High Street anchors the Sutton location plan.
- Carshalton (SM5) — a conservation area application in Carshalton starts from victorian terraces, georgian villas, and Carshalton reads as Victorian and Georgian village. Applications on Georgian stock here almost always need a heritage statement alongside the drawings in SM5. Sutton Council assesses Carshalton conservation area applications against its own Carshalton character guidance, and the location plan we draw for Carshalton references Carshalton Ponds.
- Cheam (SM2, SM3) — conservation area application work in Cheam means georgian villas, 1930s semi-detached. Cheam is Georgian village, 1930s semi-detached. Applications on Georgian stock here almost always need a heritage statement alongside the drawings throughout SM2. Sutton Council decides the Cheam application, and Cheam Village anchors the Cheam location plan.
- Wallington (SM6) — Edwardian villas, 1930s semi-detached defines Wallington, where edwardian villas, 1930s semi-detached set what a conservation area application can do. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed across SM6. Any Wallington conservation area application is validated by Sutton Council, with Wallington station the usual Wallington reference point on the site plan.
- Worcester Park (KT4) — conservation area application work in Worcester Park means 1930s semi-detached. Worcester Park is 1930s semi-detached. On these 1930s semis the prior approval route often replaces a full application throughout KT4. Sutton Council decides the Worcester Park application, and Worcester Park station anchors the Worcester Park location plan.
- Belmont (SM2) — 1930s semi-detached defines Belmont, where 1930s semi-detached set what a conservation area application can do. On these 1930s semis the prior approval route often replaces a full application across SM2. Any Belmont conservation area application is validated by Sutton Council, with Belmont station the usual Belmont reference point on the site plan.
- Hackbridge (SM6) — conservation area application work in Hackbridge means edwardian terraces, post-war. Hackbridge is Edwardian terraces, post-war. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed throughout SM6. Sutton Council decides the Hackbridge application, and Hackbridge station anchors the Hackbridge location plan.
Does Sutton planning policy restrict a conservation area application?
How designation changes a Sutton conservation area application: the council's own list runs to 17 areas, Beddington Park, Cheam Village and Sutton Central included. Inside any of them the permitted-development shortcut disappears. A £249 prior approval, decided inside 6 weeks, is replaced by a £548 householder application with 8 weeks to run. The fee gap is not the real cost. Sutton refuses 28.3% of larger-householder prior approvals — 131 refusals from 463 determinations in the three planning years to March 2026 — and the pooled London refusal share for that route is 24.9% (MHCLG PS2, Open Government Licence v3.0). Beddington Park sets the tone for casework across the borough.
Article 4 and your Sutton conservation area application: no borough-wide direction has been made here, so permitted development survives everywhere outside the 17 designated areas and the curtilages of listed buildings. Where it does still apply, a Lawful Development Certificate at £274 is how a Worcester Park or Carshalton owner puts the lawfulness on record. Sutton logged 972 certificate applications over the same twelve quarters. MHCLG publishes no grant or refusal breakdown for certificates in any English authority, so read that as a count and nothing more.
What Sutton is built from: 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. That mix decides the conservation area application route in Sutton more than the postcode does.
Who decides a conservation area application on the edge of Sutton?
- Merton — cross the Sutton boundary and Merton Council takes the conservation area application instead, applying 28 conservation areas of its own around SW16. We re-price conservation area applications at the Sutton edge because Merton policy and Sutton policy rarely align on conservation area application depth.
- Croydon — cross the Sutton boundary and Croydon Council takes the conservation area application instead, applying 24 conservation areas of its own around CR0. We re-price conservation area applications at the Sutton edge because Croydon policy and Sutton policy rarely align on conservation area application depth.
- Kingston upon Thames — adjoining Sutton, with 22 conservation areas centred on KT1. A conservation area application on the far side of the Sutton line is determined by Kingston Council, so the Sutton quote for conservation area applications is checked against Kingston upon Thames guidance before it is issued.
