Most homeowners in Croydon start by Googling the application fee. That's fair enough — but the fee is probably the least complicated part of what you're about to spend. The real cost question isn't just what you pay to submit. It's what you pay when things go wrong, take longer than expected, or turn out to need a different process entirely. WhatCanIBuild exists because that gap between "I looked it up" and "I actually know" is where expensive mistakes happen.
The short version
- The standard householder application fee in Croydon is £258 — but that's rarely the full picture
- A £75.83 +VAT service charge applies to online applications attracting fees over £100
- Your property's specific constraints can change both what you need and what it costs
The fee you know about — and the ones you don't
The householder application fee in Croydon is £258. If you submit online through the Planning Portal, add a service charge of £75.83 +VAT on top of that. So before you've paid a professional or drawn a single plan, you're already past £300.
But here's what most homeowners don't budget for: the costs that come before the application. Architectural drawings. A planning consultant if your project is anything other than straightforward. Pre-application advice from the council. These can easily dwarf the fee itself — and whether you need them depends almost entirely on your specific property and project type.
Why Croydon isn't one place — it's many
Croydon covers CR0, CR2, CR5, CR7, CR8, and SE25. That's a lot of ground, and it's not uniform. The southern parts of the borough sit in the Green Belt. The town centre is mid-regeneration with its own local planning policies. Conservation areas exist across the borough, and Article 4 directions can quietly strip away the permitted development rights that most people assume they have.
If your property sits in a conservation area, near a listed building, in a flood zone, or under an Article 4 direction, the cost and complexity of your project can shift significantly — sometimes before you've even submitted anything. Most homeowners don't realise their property has any of these overlays until something goes wrong.
Important
Listed building consent and planning permission for demolition in a conservation area don't carry an application fee — but the process is considerably more involved, and getting it wrong is costly. If your property or its surroundings have any heritage designation, your situation is not standard.
The cost of getting it wrong
If you submit with the wrong fee, your application is delayed. If you proceed without permission where permission was needed, you're looking at enforcement action. If you apply and are refused, the fee isn't refunded. And if the council fails to determine your application in time, you can appeal — but that's another process entirely.
The decision timeline in Croydon is typically eight weeks. That's eight weeks of uncertainty for a project that might have been predictable from the start — if you'd known what your property's specific combination of constraints actually meant for your chances.
That's what WhatCanIBuild shows you: not just that you're in a conservation area, but what that's meant in practice for projects like yours, on streets like yours. What's been approved nearby. What's been refused, and why. The difference between knowing a constraint exists and knowing how it plays out.
The best way to know what you're actually dealing with
Before you budget, before you appoint anyone, before you assume your project is straightforward — check what your specific property is actually up against. The fee is £258. The cost of misreading your situation is considerably more.
