Plenty of homeowners in Surrey Heath assume planning permission is a formality — you fill in the forms, pay the fee, and wait eight weeks. But the reality is that approval odds vary enormously depending on your specific property, your street, and the kind of project you're proposing. WhatCanIBuild exists precisely because that complexity is almost impossible to unpick without looking at your address directly.
The short version
- Surrey Heath has 11 conservation areas, 382 listed buildings, and significant Green Belt coverage — all of which affect what you can do
- Your approval odds aren't just about the project type — they're about your property's specific combination of constraints
- What's been approved or refused on your street is often the most useful signal, and most homeowners never check it
Your postcode is just the starting point
Surrey Heath covers GU15, GU16, GU18, GU20, GU24 and more — but being in the same postcode as your neighbour doesn't mean you're in the same planning situation. Conservation area boundaries can cut through streets. Article 4 directions can remove permitted development rights from some properties but not others. A listed building designation affects not just the main structure but often what you can do in the curtilage around it.
Most homeowners don't realise how localised these designations are until they're already mid-application — or until they've received a refusal.
Green Belt land changes everything
Parts of Surrey Heath fall within the Green Belt, and this is where a lot of applications run into trouble. Green Belt policy is strict, and the threshold for what gets approved is meaningfully different from non-Green Belt land. But here's the thing: knowing you're near Green Belt land isn't the same as knowing whether your property sits within it, or how that affects your specific project type.
Extensions that would sail through in Camberley town centre can face a very different reception if your property is on the edge of the borough. The rules don't change — but what they mean for your application absolutely does.
Conservation Areas
Surrey Heath has 11 designated conservation areas. If your property falls within one, permitted development rights for external alterations may be restricted or removed entirely — even for changes you'd assume were minor.
Listed buildings and the detail that catches people out
With 382 listed buildings recorded across the borough, the chances that your property — or a neighbouring one — carries a designation are higher than most people expect. Listed building consent is separate from planning permission, and the two processes have different criteria, different fees, and different consequences if you get it wrong.
But even if your home isn't listed, proximity to a listed building can influence how Surrey Heath Borough Council views your application. It's one of those factors that rarely appears in a basic planning guide but regularly appears in decision notices.
What approval odds actually look like for your property
The best way to understand your real chances isn't to look at national statistics or borough-wide approval rates. It's to see what's been approved and refused for similar projects, on similar properties, in your specific part of Surrey Heath — and why. WhatCanIBuild pulls that picture together for your address, so you're not guessing based on what worked for someone else's house.
The £548 householder application fee is just the beginning. Factor in design costs, surveys, and the time lost to a refusal, and the stakes for getting the preparation right are considerable.
Before you commit to an application — or assume you don't need one — WhatCanIBuild gives you a property-specific read on what your approval odds actually look like, what's been decided nearby, and what constraints are quietly working against you.
