How much does planning permission really cost in Bexley?

The standard householder planning application fee in Bexley is £258. That number is easy to find. What's harder to find — and what catches most homeowners off guard — is everything else that sits on top of it, around it, and underneath it. WhatCanIBuild exists precisely because the real question isn't what the fee is — it's whether your project even needs permission, and if it does, what it's actually going to cost you to get it.

The £258 is just the application fee

When you submit a planning application online, there's also a service charge of £75.83 + VAT on top of the fee. That's before you've paid anyone to prepare your application.

Most homeowners need professional drawings. Many need a planning agent or architect to submit on their behalf. Some projects trigger the need for additional reports — ecology surveys, heritage statements, flood risk assessments — depending on what constraints apply to the property. Each of those adds cost. None of them are optional if the council asks for them.

The total cost of getting planning permission in Bexley can range from a few hundred pounds to several thousand. Your property's location and history determines where you fall on that range.

Bexley isn't a uniform borough

This is where most people underestimate the complexity. Bexley covers postcodes from DA5 to DA18, plus parts of SE2 and SE9. Within that area, you have Green Belt land to the south and east — where permitted development rights are restricted and the bar for what needs permission is higher. You have conservation areas. You have streets with Article 4 directions that remove rights that most properties take for granted. And you have individual listed buildings scattered across the borough.

Most homeowners don't realise that two houses on the same road can have completely different planning obligations. One might need full permission for a rear extension. The other might not need permission at all — or might need permission and a heritage statement.

The cost of getting it wrong

Submitting the wrong application, or submitting without the right supporting documents, doesn't just delay your project. It can invalidate your application entirely. Fees aren't refunded if your application is withdrawn or invalid. If the council fails to decide in time, you can appeal — but that process takes time and often money too.

And if you skip permission on something that needed it? Enforcement action is a real possibility, and the cost of retrospective applications — or worse, having to undo the work — far exceeds the original fee.

What actually applies to your property

The best way to understand your real planning position isn't to look up the fee schedule — it's to understand what's been approved and refused for properties like yours, on streets like yours, in Bexley's planning history. WhatCanIBuild shows you what similar projects on your street actually got approved or refused, and why — the kind of intelligence that turns a vague budget estimate into something you can actually plan around.

Knowing you're near a conservation area is one thing. Knowing what that means for your specific extension, on your specific plot, based on what Bexley Council has actually decided — that's what changes your planning strategy.

WhatCanIBuild gives you a property-level picture of your approval odds, the constraints that apply to you, and what comparable projects in your area have actually cost to get through.
