Answers for Hillingdon

Does Hillingdon have listed buildings?

Yes. Hillingdon has hundreds of listed buildings, particularly in Uxbridge, Ruislip Village, Northwood, Harefield, Ickenham. Listed Building Consent is required for any work affecting character — internal or external.

What's the difference between planning permission and Listed Building Consent?

Planning permission concerns the visual and use impact on the surroundings. Listed Building Consent concerns the heritage value of the building itself — fabric, features, character. Most listed-building works need both.

How long does Listed Building Consent take in Hillingdon?

8 weeks statutory, but with conservation officer and Historic England consultation, expect 12–16 weeks. Grade I and Grade II* always involve Historic England.

What's involved in a listed building application?

Detailed measured survey, existing-condition drawings, proposed drawings, Heritage Statement, materials specification, and a justification for every change. Photographs of every affected feature.

Can I refuse internal change permission for a listed building?

No. Listed status protects internal features as well — period plasterwork, joinery, fireplaces, staircases. Removal without consent is a criminal offence.

Uxbridge is the Hillingdon designation that most often changes a listed building consent application design.

Article 4 and your Hillingdon listed building consent application: Hillingdon Council has made no borough-wide direction, so permitted development for a listed building consent application in Hillingdon generally survives outside Hillingdon conservation areas and listed curtilages.
