What planning rules in Reigate and Banstead catch homeowners out?

Planning rules in Reigate and Banstead look straightforward until they aren't. Many homeowners assume their project falls under permitted development, start work, and only discover the problem when a neighbour complains or they try to sell. The borough's mix of Surrey Hills AONB proximity, 19 conservation areas, and hundreds of listed buildings creates a patchwork of restrictions that varies street by street — and sometimes property by property. WhatCanIBuild exists precisely for situations like this, where the general rules don't tell the full story.

Being near the Surrey Hills AONB isn't the same as being outside it

A lot of homeowners in postcodes like RH2, KT20, and RH6 assume they're fine because they're not in the Surrey Hills AONB. But Article 1(5) land — which covers areas in or adjacent to the AONB — applies tighter restrictions on permitted development. What you can build without permission in a standard suburban street may require a full application if your property sits on this land. Most homeowners don't realise their garden, outbuilding, or roofline falls within scope until it's too late.

Conservation areas are not all the same

The borough's 19 conservation areas don't follow a single rulebook. What's permitted in one may require an application in another. External alterations that look identical — a new front door, replacing windows, adding a small porch — can have completely different planning implications depending on which conservation area you're in, and sometimes which part of that area. Add to that the possibility of an Article 4 direction withdrawing permitted development rights in specific streets, and the calculation becomes genuinely difficult to make without checking your specific address.

Listed buildings catch more than the obvious cases

With 457 listed buildings in Reigate and Banstead, the borough has a significant number of properties where Listed Building Consent applies on top of — or instead of — standard planning permission. But it's not just the listed building itself. Curtilage structures, outbuildings, and sometimes neighbouring properties can fall within the protected zone. If you're unsure whether your property or a nearby structure carries listed status, that uncertainty alone is worth resolving before any work begins.

The gap between knowing the rules and knowing your position

The general rules for permitted development are publicly available. But knowing you're in a conservation area isn't the same as knowing what that means for your specific project on your specific plot. WhatCanIBuild goes further than the basics — showing you what's been approved and refused for similar projects nearby, what your approval odds look like given your property's combination of constraints, and whether projects like yours on your street have actually gone through. That's the information that changes a guess into a decision.

With a householder application fee of £548 and an 8-week decision window, submitting an application you didn't need is frustrating. Carrying out work that needed one is considerably worse. The best way to know where you actually stand is to check your property directly.

WhatCanIBuild gives you a clear picture of what your address's history and constraints actually mean for your project — not just the rules in the abstract.
