How much does planning permission really cost in Tonbridge and Malling?

Most homeowners in Tonbridge and Malling assume planning permission costs whatever the council charges. The reality is more complicated — and more expensive — than that. The fee is just the beginning, and the variables that sit underneath it depend entirely on your specific property. WhatCanIBuild exists precisely because those variables are almost impossible to untangle without looking at your address directly.

The £548 fee is the easy part

Yes, a householder planning application in Tonbridge and Malling costs £548. But most homeowners don't realise that fee is non-refundable whether your application is approved or refused. If your application is withdrawn before a decision, you also don't get it back. Submit the wrong application type and you're starting again.

On top of that, if you submit through the Planning Portal, a service charge of £75.83 + VAT applies to applications attracting a fee over £100. That's before you've paid anyone to draw plans, write a supporting statement, or give you pre-application advice from the council.

None of that is the expensive part. The expensive part is finding out — after submission — that your property had a constraint you didn't know about.

Tonbridge and Malling is unusually complex

This borough covers a wide geographic area, from commuter towns like Tonbridge itself to deeply rural parishes bordering the Kent Downs. That mix creates a patchwork of planning conditions that varies dramatically street by street.

The borough has 60 conservation areas. That's not a small number. It means a significant proportion of residential streets carry heritage restrictions on external alterations that simply don't apply elsewhere. Most homeowners don't realise their street is in one until they've already committed to a project.

There are also 1,323 listed buildings across the borough. If your property is listed — or even adjacent to one — the rules governing what you can do, how you can do it, and what it will cost to demonstrate compliance are in a different category entirely. Listed building consent carries no application fee, but the professional costs involved in getting it right can be substantial.

Then there's Article 1(5) land. Properties in or near the Kent Downs AONB fall under restricted permitted development rights. Work that would be straightforward elsewhere may require a full application here — and the planning officer's approach to it will be different too.

What you really need to know before you spend anything

The question isn't just "how much does planning permission cost?" It's "how much will planning permission cost for my property, for this project, given what's already been decided nearby?"

That's a different question — and it's one WhatCanIBuild is built to answer. The best way to understand your real position isn't to look up the fee schedule. It's to see what's been approved and refused on your street, what constraints are stacked against your address, and what that combination actually means for your chances.

Most homeowners in Tonbridge and Malling start planning their budget before they've looked at any of that. That's when the surprises happen.

If you're about to commit money to a project — even just to professional fees for drawings — WhatCanIBuild gives you a clearer picture of your specific property before you spend a penny on the application itself.
