Where in UB9 does a drawing package actually get determined?
Every UB9 postcode district we draw in, the stock that dominates
it and the authority that validates a drawing package there. UB9 fees below are the
statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|
| UB9 | Denham / Harefield | Tudor and Georgian fragments, 1930s semi-detached | UB9 is a two-council postcode. The Greater London boundary runs through it: Harefield addresses fall to Hillingdon Council, Denham addresses to Buckinghamshire Council. Neither authority will take an application for the other's territory, so it is the address that fixes where drawings are submitted and never the postcode. |

What local planning policy applies to a drawing package in UB9?
How designation changes a UB9 (Denham / Harefield) drawing package: Hillingdon Council maintains 29 conservation areas, including Ickenham, Uxbridge, Ruislip Village. Inside any of them a UB9 (Denham / Harefield) drawing package 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. Ruislip Village sets the tone for UB9 (Denham / Harefield) casework.
UB9 (Denham / Harefield) permitted development status: there is no borough-wide direction from Hillingdon Council, so a drawing package at a UB9 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a UB9 (Denham / Harefield) sale to argue it later.
UB9 (Denham / Harefield) 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. Largest outer west London borough; significant Green Belt; Heathrow noise contours affect planning decisions in Harmondsworth and Sipson. Read that before choosing a drawing package route in UB9 (Denham / Harefield) — construction, not postcode, sets what is achievable. Hillingdon Council charges £548 for a householder application and has 8 weeks to determine it.
Which neighbouring authorities border UB9?
- Harrow — cross the UB9 (Denham / Harefield) boundary and Harrow Council takes the drawing package instead, applying 29 conservation areas of its own around HA1. We re-price architectural drawings at the UB9 (Denham / Harefield) edge because Harrow policy and Hillingdon policy rarely align on drawing package depth.
- Ealing — Ealing does border Hillingdon, but nowhere near UB9. That shared edge lies several miles to the south-east, around Northolt and Greenford, and no Harefield or Denham address is decided by Ealing Council. If you are comparing quotes across west London, treat Ealing as a separate market rather than a neighbour of this postcode.
- Hounslow — Hounslow meets Hillingdon at the southern end of the borough, near Cranford and Heathrow, a long way from UB9. Nothing in Harefield or Denham is determined by Hounslow Council. At the northern tip of Hillingdon the councils that genuinely matter are Buckinghamshire, immediately over the boundary at Denham, and Three Rivers District beyond Harefield in Hertfordshire.
