Where in Hillingdon does a drawing package actually get determined?

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.

PostcodeAreaDominant stockWhat it means for a drawing package
UB10Hillingdon / Ickenham1930s semi-detached, Tudor fragmentsA drawing package at an UB10 address in Hillingdon / Ickenham is determined by Hillingdon Council under its own Local Plan policies for Hillingdon / Ickenham.
UB11Stockley Park1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near HeathrowA drawing package at an UB11 address in Stockley Park is determined by Hillingdon Council under its own Local Plan policies for Stockley Park.
HA4Ruislip1930s semi-detached, Tudor cottagesRuislip sits wholly inside HA4, so Hillingdon Council validates every drawing package submitted from an HA4 address.
HA5Pinner / EastcoteTudor fragments, Edwardian villas, 1930s semi-detachedA drawing package in Pinner / Eastcote may land with Hillingdon Council or Harrow Council — HA5 crosses the boundary, and the HA5 policies map decides it street by street.

UB3Hayes / Harlington1930s semi-detached, post-war estatesA drawing package at an UB3 address in Hayes / Harlington is determined by Hillingdon Council under its own Local Plan policies for Hayes / Harlington.

Which Hillingdon neighbourhoods suit a drawing package best?

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.

Does Hillingdon planning policy restrict a drawing package?

Conservation areas covering Hillingdon: Hillingdon Council runs 29, and Harefield, Ickenham, Uxbridge 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 £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Uxbridge a drawing package is judged on the street elevation first.

No blanket Article 4 over Hillingdon: Hillingdon Council has not withdrawn permitted development across Hillingdon, so a drawing package outside a Hillingdon conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a HA4 owner wants on file.

The building fabric around Hillingdon: 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. A drawing package in Hillingdon is scoped against that stock first.
