Most homeowners in Durham start with one question: how much does planning permission cost? The headline answer — £548 for a householder application — sounds simple enough. But that number is just the beginning, and the real cost depends heavily on factors tied to your specific property. WhatCanIBuild exists precisely because the gap between that headline fee and your actual situation can be significant.
The short version
- The standard householder application fee in Durham is £548
- Durham has 92 conservation areas and 3,136 listed buildings — your property may be affected without you knowing
- Additional costs stack up quickly depending on your property's constraints
- The best way to understand what applies to your property is to check before you commit
The £548 is only part of what you'll pay
The application fee is set nationally, so Durham County Council charges the same £548 as anywhere else in England for a householder application. But most homeowners don't realise that's rarely the final bill. If you submit online through the Planning Portal, a service charge of £75.83 + VAT applies to applications attracting fees over £100. That's before you've paid for drawings, a planning consultant, or any specialist reports your application might require.
And here's where it gets complicated: what your application requires depends entirely on your property.
Durham's heritage coverage is extensive — and it affects costs
Durham isn't just a county with some historic streets. It sits alongside two National Parks (North York Moors and Yorkshire Dales), the North Pennines AONB, and the Durham Castle and Cathedral World Heritage Site — which also falls within the Frontiers of the Roman Empire designation covering Hadrian's Wall. Properties near those boundaries fall on Article 1(5) land, where your permitted development rights are already restricted in ways most homeowners never discover until it's too late.
Then there are the 92 conservation areas across the county. If your property sits within one — and you may not know for certain without checking — the rules around external alterations change. That can mean heritage impact assessments, bat surveys, or other reports that add hundreds or thousands to your project costs before a single brick is moved.
With 3,136 listed buildings recorded across Durham, the chance that your property — or a neighbouring one — carries a designation that affects your application isn't trivial.
Important
Listed building consent is separate from planning permission and carries no application fee — but the professional costs involved in preparing a compliant application can be substantial. Assuming your project only needs a standard application could be a costly mistake.
The questions most homeowners can't answer alone
Knowing you're near a conservation area is one thing. Knowing what that actually means for your specific project — whether similar extensions on your street have been approved or refused, what conditions were attached, and how Durham County Council has treated comparable applications nearby — is something else entirely.
That's the gap most homeowners fall into. They budget for the fee. They don't budget for a refused application, a redesign, or a resubmission. And they definitely don't account for the cost of getting it wrong.
WhatCanIBuild shows you what's actually been approved and refused near your property, what your specific combination of constraints means for your project type, and what your real approval odds look like — not just the rules in theory, but how they've played out for similar homes on similar streets in Durham.
The fee is fixed. Everything else around it isn't — and the best way to understand your actual exposure before you spend anything is to check your property first.
WhatCanIBuild gives you the property-specific picture that this article — or any article — simply can't.
