Every Hillingdon postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. Hillingdon fees below are the statutory England rates for 2026, not planning drawing set estimates.
| Postcode | Area | Dominant stock | What it means for a planning drawing set |
|---|---|---|---|
| HA5 | Pinner / Eastcote | Tudor fragments, Edwardian villas, 1930s semi-detached | HA5 straddles a boundary: Pinner / Eastcote addresses fall to Hillingdon Council or Harrow Council, so confirm which authority validates the planning drawing set before submitting HA5 drawings. |
| HA6 | Northwood | 1930s detached, Edwardian villas | HA6 covers Northwood only; Hillingdon Council handles the planning drawing set, and Northwood case officers apply the HA6 conservation-area map. |
| UB3 | Hayes / Harlington | 1930s semi-detached, post-war estates | A planning drawing set 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 planning drawing set, and Hayes / Yeading case officers apply the UB4 conservation-area map. |
| UB7 | West Drayton / Sipson / Harmondsworth | 1930s semi-detached, post-war | West Drayton / Sipson / Harmondsworth sits wholly inside UB7, so Hillingdon Council validates every planning drawing set submitted from an UB7 address. |
| UB8 | Uxbridge / Cowley | Georgian fragments, 1930s semi-detached, post-war flats | Uxbridge / Cowley sits wholly inside UB8, so Hillingdon Council validates every planning drawing set submitted from an UB8 address. |
| UB9 | Denham / Harefield | Tudor and Georgian fragments, 1930s semi-detached | Denham / Harefield sits wholly inside UB9, so Hillingdon Council validates every planning drawing set submitted from an UB9 address. |
| UB10 | Hillingdon / Ickenham | 1930s semi-detached, Tudor fragments | A planning drawing set at an UB10 address in Hillingdon / Ickenham is determined by Hillingdon Council under its own Local Plan policies for Hillingdon / Ickenham. |
Roof pitch, wall build-up and plot depth change every few Hillingdon streets, and each one changes what a planning drawing set can achieve at that address.
How designation changes a Hillingdon planning drawing set: Hillingdon Council maintains 29 conservation areas, including Ickenham, Uxbridge, Ruislip Village. Inside any of them a Hillingdon planning drawing set cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Northwood sets the tone for Hillingdon casework.
Hillingdon permitted development status: there is no borough-wide direction from Hillingdon Council, so a planning drawing set at a HA4 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Hillingdon sale to argue it later.
What Hillingdon is built from: 1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near Heathrow. Largest outer west London borough; significant Green Belt; Heathrow noise contours affect planning decisions in Harmondsworth and Sipson. That mix decides the planning drawing set route in Hillingdon more than the postcode does, and it is what a Hillingdon Council case officer reads first. A householder application costs £548 paid to Hillingdon Council direct, with 8 weeks to a decision once validated.

Of 510 appeals on new-dwelling schemes decided in Hillingdon over the window covering appeals decided 2016-2026, Hillingdon sat close to the London norm, with 24.9% of appeals succeeding against 22.4% city-wide. 127 were allowed and 382 dismissed, with 1 split. Schemes creating a new home - conversions, infills, small developments - carry the most risk, and these 510 Hillingdon appeals are only the ones refused or left undetermined, never the approvals.
Half of those Hillingdon appeals took more than 95 days to decide from the day the appeal started — time added on top of the council's own determination period, which is the argument for getting the application right first. 98.4% were decided by written representations rather than a hearing or inquiry, meaning the written case and the drawings were the whole of the evidence.
