Every Kingston upon Thames postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Kingston upon Thames fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| KT1 | Kingston upon Thames | Georgian fragments, Victorian terraces, 1930s semi-detached | Kingston upon Thames sits wholly inside KT1, so Kingston Council validates every drawing package submitted from an KT1 address. |
| KT2 | Kingston / Norbiton | Georgian fragments, Victorian terraces, 1930s semi-detached | Kingston / Norbiton sits wholly inside KT2, so Kingston Council validates every drawing package submitted from an KT2 address. |
| KT3 | New Malden | Edwardian villas, 1930s semi-detached | New Malden sits wholly inside KT3, so Kingston Council validates every drawing package submitted from an KT3 address. |
| KT5 | Surbiton / Tolworth | Edwardian villas, mansion blocks | KT5 covers Surbiton / Tolworth only; Kingston Council handles the drawing package, and Surbiton / Tolworth case officers apply the KT5 conservation-area map. |
| KT6 | Surbiton | Edwardian villas, mansion blocks | KT6 covers Surbiton only; Kingston Council handles the drawing package, and Surbiton case officers apply the KT6 conservation-area map. |
| KT9 | Chessington | 1930s semi-detached | KT9 covers Chessington only; Kingston Council handles the drawing package, and Chessington case officers apply the KT9 conservation-area map. |
Roof pitch, wall build-up and plot depth change every few Kingston upon Thames streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering Kingston upon Thames: Kingston Council runs 22, and Kingston Old Town, Surbiton, Hampton Wick are the ones Kingston upon Thames owners meet most. A drawing 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 Coombe Hill a drawing package is judged on the street elevation first.
Article 4 and your Kingston upon Thames drawing package: Kingston Council has made no borough-wide direction, so permitted development for a drawing package in Kingston upon Thames generally survives outside Kingston upon Thames conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a KT1 owner records that a drawing package was lawful.
The building fabric around Kingston upon Thames: 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. A drawing package in Kingston upon Thames 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 Kingston Council.

Over the 12 quarters from 2023 Q2 to 2026 Q1, Kingston upon Thames decided 2,454 householder planning applications and approved 78.4% of them — 4.6 percentage points below the London average of 83%. That places Kingston upon Thames 26th of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.
| Measure | Kingston upon Thames | Context |
|---|---|---|
| Householder applications decided | 2,454 | 77,680 across London |
| Householder approval rate | 78.4% | 83% London average |
| Decided within 8 weeks | 92.7% | 17th fastest of 32 boroughs |
| Took longer than 13 weeks | 1.7% | the applications that overran the statutory target |
| Minor dwellings approval rate | 44.7% | new-build and conversion schemes under 10 units |
| All application types | 73.5% | across 3,488 decisions |
| Certificates of lawfulness issued | 969 | confirmations that work was permitted development |
Speed matters as much as the odds. Kingston upon Thames decided 92.7% of householder applications inside the eight-week statutory period and let 1.7% run past thirteen weeks. A drawing package that is complete and correctly described at validation is the part of that timeline you control; the rest belongs to the council's caseload.
