How Listed Building Consent works in Harrow, when you need it, and how to get a sensitive design approved.
Yes. Harrow has hundreds of listed buildings, particularly in Harrow on the Hill, Pinner Village, Stanmore, Harrow Weald. Listed Building Consent is required for any work affecting character — internal or external.
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.
8 weeks statutory, but with conservation officer and Historic England consultation, expect 12–16 weeks. Grade I and Grade II* always involve Historic England.
Detailed measured survey, existing-condition drawings, proposed drawings, Heritage Statement, materials specification, and a justification for every change. Photographs of every affected feature.
No. Listed status protects internal features as well — period plasterwork, joinery, fireplaces, staircases. Removal without consent is a criminal offence.



Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every Harrow postcode district we draw in, the stock that dominates it and the authority that validates a listed building consent application there. Harrow fees below are the statutory England rates for 2026, not listed building consent application estimates.
| Postcode | Area | Dominant stock | What it means for a listed building consent application |
|---|---|---|---|
| HA1 | Harrow / Harrow on the Hill | Georgian and Victorian houses, listed buildings | A listed building consent application at an HA1 address in Harrow / Harrow on the Hill is determined by Harrow Council under its own Local Plan policies for Harrow / Harrow on the Hill. |
| HA2 | North Harrow / South Harrow | 1930s semi-detached | A listed building consent application at an HA2 address in North Harrow / South Harrow is determined by Harrow Council under its own Local Plan policies for North Harrow / South Harrow. |
| HA3 | Harrow Weald / Kenton / Wealdstone | 1930s semi-detached | A listed building consent application at an HA3 address in Harrow Weald / Kenton / Wealdstone is determined by Harrow Council under its own Local Plan policies for Harrow Weald / Kenton / Wealdstone. |
| HA7 | Stanmore | 1930s semi-detached, Edwardian villas | Stanmore sits wholly inside HA7, so Harrow Council validates every listed building consent application submitted from an HA7 address. |
| HA5 | Pinner / Eastcote | Tudor fragments, Edwardian villas, 1930s semi-detached | A listed building consent application 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. |
Roof pitch, wall build-up and plot depth change every few Harrow streets, and each one changes what a listed building consent application can achieve at that address.
Harrow conservation designations: there are 29 across Harrow Council, Harrow Weald, Harrow on the Hill, Pinner Village among them. Designation costs a Harrow owner the permitted-development route: a listed building consent application then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Pinner Village is the Harrow designation that most often changes a listed building consent application design.
Harrow permitted development status: there is no borough-wide direction from Harrow Council, so a listed building consent application at a HA1 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Harrow sale to argue it later.
Harrow housing stock: 1930s semi-detached dominates; Edwardian villas in Harrow on the Hill and Pinner; Metropolitan Green Belt in Stanmore and Harrow Weald; post-war flats around Harrow Central. Outer north-west London suburban; Harrow on the Hill has exceptionally strict heritage controls; rest of borough permissive. Read that before choosing a listed building consent application route in Harrow — construction, not postcode, sets what is achievable.
