Every Hillingdon postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Hillingdon fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| UB3 | Hayes / Harlington | 1930s semi-detached, post-war estates | A drawing package at an UB3 address in Hayes / Harlington is determined by Hillingdon Council under its own Local Plan policies for Hayes / Harlington. |
| UB4 | Hayes / Yeading | 1930s semi-detached, post-war estates | UB4 covers Hayes / Yeading only; Hillingdon Council handles the drawing package, and Hayes / Yeading case officers apply the UB4 conservation-area map. |
| UB7 | West Drayton / Sipson / Harmondsworth | 1930s semi-detached, post-war | UB7 covers West Drayton / Sipson / Harmondsworth only; Hillingdon Council handles the drawing package, and West Drayton / Sipson / Harmondsworth case officers apply the UB7 conservation-area map. |
| UB8 | Uxbridge / Cowley | Georgian fragments, 1930s semi-detached, post-war flats | UB8 covers Uxbridge / Cowley only; Hillingdon Council handles the drawing package, and Uxbridge / Cowley case officers apply the UB8 conservation-area map. |
| UB9 | Denham / Harefield | Tudor and Georgian fragments, 1930s semi-detached | UB9 covers Denham / Harefield only; Hillingdon Council handles the drawing package, and Denham / Harefield case officers apply the UB9 conservation-area map. |
| UB10 | Hillingdon / Ickenham | 1930s semi-detached, Tudor fragments | A drawing package at an UB10 address in Hillingdon / Ickenham is determined by Hillingdon Council under its own Local Plan policies for Hillingdon / Ickenham. |
| UB11 | Stockley Park | 1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near Heathrow | A drawing package at an UB11 address in Stockley Park is determined by Hillingdon Council under its own Local Plan policies for Stockley Park. |
| HA4 | Ruislip | 1930s semi-detached, Tudor cottages | Ruislip sits wholly inside HA4, so Hillingdon Council validates every drawing package submitted from an HA4 address. |
Roof pitch, wall build-up and plot depth change every few Hillingdon streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering Hillingdon: Hillingdon Council runs 29, and Uxbridge, Ruislip Village, Northwood are the ones Hillingdon owners meet most. A drawing package inside a Hillingdon conservation area loses permitted development, so the Hillingdon submission is a householder application at £258 decided in 8 weeks — not a £120 prior approval decided in 6 weeks. In Ickenham a drawing package is judged on the street elevation first.
Hillingdon permitted development status: there is no borough-wide direction from Hillingdon Council, so a drawing package at a HA4 address is normally still permitted development. We certify that with a £129 Lawful Development Certificate rather than leaving a Hillingdon sale to argue it later.
Hillingdon housing stock: 1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near Heathrow.

Read that before choosing a drawing package route in Hillingdon — construction, not postcode, sets what is achievable.
