How much does planning permission really cost in Stevenage?

Most Stevenage homeowners assume planning permission costs whatever the application fee says. They're usually wrong — and the gap between what they expect and what they actually spend can be significant.

The headline fee for a householder application is £548. But that number doesn't tell you much about what your project will actually cost, or whether it'll even be approved. WhatCanIBuild can show you what's been approved on properties like yours in Stevenage — which is a very different thing from knowing the fee.

The fee is just the entry ticket

Pay £548 and you've bought yourself a decision — not an approval. If your application is refused, that fee doesn't come back to you. Neither does the time you spent preparing it. Most homeowners don't realise that a refused application means starting again, potentially with professional help they didn't budget for the first time.

And if you submit online via the Planning Portal, add £75.83 + VAT as a service charge on top. That applies to most standard applications.

Stevenage has layers most people don't see

Stevenage Borough has 7 conservation areas, 130 listed buildings, and Green Belt land covering parts of the borough. Any one of these can change what's possible on your property — and how much it costs to prove your proposal is acceptable.

If your home sits within or near a conservation area, your application may need additional supporting documents. A heritage statement, design and access statement, or specialist arborist report can each add hundreds of pounds before you've submitted anything. Most homeowners don't realise they need these until they're already in the process.

Listed building consent — if your property requires it — carries no application fee, but the supporting work required to get it right isn't free.

The costs you don't see coming

Beyond the application fee, typical additional costs can include:

• Architectural drawings — most councils won't accept hand-sketched plans
• Planning consultants — increasingly common in complex or borderline cases
• Pre-application advice — Stevenage Borough Council charges for formal pre-app advice, but many homeowners skip it and pay more later
• Resubmission — if your application is refused, you may face the full fee again

The real question isn't what the fee is. It's whether your specific project, on your specific property, in your specific part of Stevenage, is likely to be approved in the first place — and what you'll need to spend to make the case.

What actually matters for your project

Knowing you're in a conservation area is not the same as knowing what that means for your loft conversion, extension, or outbuilding. The best way to understand your actual position is to see what's happened on similar properties nearby — what got approved, what got refused, and why.

WhatCanIBuild shows you approval patterns for your specific project type in Stevenage, including how your property's combination of constraints affects your chances. That's the information that changes how you plan — and what you budget.
