How much does planning permission really cost in Stockport?

Most Stockport homeowners who ask this question are thinking about one number. The truth is, that number is almost never the whole story — and until you see exactly what your property's constraint mix looks like — free, in about a minute, you're probably underestimating what's ahead.

The £548 is just the entry ticket

Stockport Council charges £548 for a householder planning application — extensions, loft conversions, outbuildings, that kind of thing. Pay it, wait up to 8 weeks, and you'll get a decision. Simple enough on paper.

But that fee assumes your application is clean: right documents, right drawings, right supporting information. Most homeowners don't realise that if your application is invalid, returned, or refused and needs resubmitting, you're looking at additional fees and additional months. And if your project sits in a grey area — something that might need permission, or might qualify as permitted development — you could end up paying for a formal Lawful Development Certificate on top.

Then there are the professional costs. Architects, planning consultants, structural engineers, arboriculturists — depending on your project and your property, any or all of these can be necessary before you even reach the application stage. None of that is included in the £548.

Stockport's geography makes this more complicated than most

Here's what catches people out: the same project, on two different streets in Stockport, can have entirely different requirements and entirely different odds of success.

The borough has conservation areas covering Stockport Town Centre, Bramhall, Marple, Hazel Grove, and Cheadle. Properties near St Mary's Church and the Underbank area sit close to listed building clusters. The southern and eastern fringes of the borough fall within Green Belt. And then there's the borough's proximity to the Peak District National Park to the east — triggering Article 2(3) designated land rules that strip back what you can do without permission.

The Goyt and Tame river corridors add flood risk considerations that can require specialist flood risk assessments before a decision is even made. That's another cost many homeowners only discover mid-process.

What refusals actually cost

A refusal isn't just a setback — it's a cost. You don't get the application fee back if your application is refused. If you appeal, that process adds months and potentially further professional fees. If you reapply with a revised scheme, that's another fee.

Most homeowners don't think about refusal risk when they're budgeting. They should. The best way to avoid it is understanding what's been approved and refused on nearby streets — not just whether your area has a conservation area designation, but what that designation has actually meant for similar projects near you. You can check what similar projects on your street have been approved for before you commit to anything.

So what's the real number?

It depends on your property. A clean permitted development project that just needs a Lawful Development Certificate might cost less than you expect. A full planning application in a conservation area near a listed building, with flood risk to address, could run into thousands before the council has even looked at it.
