Which Kingston upon Thames postcodes does this building regulations package service cover?
Kingston Council agreed an extension of time on 544 of the 3,488 applications it decided from April 2023 to March 2026 — 15.6%, against 34.5% across the 33 boroughs — so a timetable here tends to hold to the statutory clock rather than being renegotiated part-way through. The list below runs through each postcode in turn: what stands there, and which body signs a building regulations package off for it. Fees listed are England statutory rates for 2026 and not an estimate of what a package costs. Source: MHCLG live planning statistics.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|
| KT1 | Kingston upon Thames | Georgian fragments, Victorian terraces, 1930s semi-detached | KT1 sits entirely inside the borough. Kingston Council handles the package, and its officers work from the KT1 conservation-area designations wherever the address is a designated one. |
| KT2 | Kingston / Norbiton | Georgian fragments, Victorian terraces, 1930s semi-detached | Kingston and Norbiton lie wholly within KT2, so every building regulations package sent from a KT2 address is validated by Kingston Council. |
| KT3 | New Malden | Edwardian villas, 1930s semi-detached | New Malden addresses in KT3 belong to Kingston Council, assessed under its own Local Plan policies. The Motspur Park fringe of the district carries on across the boundary into Merton, so an address out that way is worth confirming. |
| KT5 | Surbiton / Tolworth | Edwardian villas, mansion blocks | Surbiton and Tolworth together make up KT5. Kingston Council receives the package, and the KT5 conservation-area designations are what its officers check an address against. |
| KT6 | Surbiton | Edwardian villas, mansion blocks | KT6 is Surbiton, and Kingston Council determines the building regulations package under the Local Plan policies that apply there. |
| KT9 | Chessington | 1930s semi-detached | Chessington accounts for the whole of KT9. The package goes to Kingston Council, whose officers apply whichever conservation-area designations cover that part of the borough. |

What local planning policy applies to a building regulations package in Kingston upon Thames?
Conservation areas covering Kingston upon Thames: Kingston Council runs 22, and Surbiton, Hampton Wick, Coombe Hill are the ones Kingston upon Thames owners meet most. A building regulations package inside a Kingston upon Thames conservation area loses permitted development, so the Kingston upon Thames submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Surbiton a building regulations package is judged on the street elevation first.
No blanket Article 4 over Kingston upon Thames: Kingston Council has not withdrawn permitted development across Kingston upon Thames, so a building regulations package outside a Kingston upon Thames conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a KT1 owner wants on file.
Kingston upon Thames housing stock: Edwardian villas in Surbiton and New Malden; Victorian terraces in Kingston central; 1930s semi-detached in Chessington and Tolworth; post-war in New Malden. Outer south-west London suburban; generally permissive; riverside conservation areas add character in Kingston town. Read that before choosing a building regulations package route in Kingston upon Thames — construction, not postcode, sets what is achievable. Kingston Council charges £548 for a householder application and has 8 weeks to determine it.
What happens if a Kingston upon Thames property sits on a boundary?
- Richmond upon Thames — adjoining Kingston upon Thames, with 72 conservation areas centred on SW13. A building regulations package on the far side of the Kingston upon Thames line is determined by Richmond Council, so the Kingston upon Thames quote for building regulations drawings is checked against Richmond upon Thames guidance before it is issued.
- Merton — cross the Kingston upon Thames boundary and Merton Council takes the building regulations package instead, applying 28 conservation areas of its own around SW16. We re-price building regulations drawings at the Kingston upon Thames edge because Merton policy and Kingston upon Thames policy rarely align on building regulations package depth.
- Sutton — adjoining Kingston upon Thames, with 17 conservation areas centred on SM1. A building regulations package on the far side of the Kingston upon Thames line is determined by Sutton Council, so the Kingston upon Thames quote for building regulations drawings is checked against Sutton guidance before it is issued.
