Most Dartford homeowners searching for planning costs land on one number: £548. That's the current householder application fee. But if you think that's the whole story, you're about to get a very expensive surprise.
The fee is just the entry ticket. What you actually spend depends on your property, your street, and a combination of local factors that most people don't discover until they're already mid-project. WhatCanIBuild can show you what's actually been approved — and refused — for properties like yours in Dartford, before you commit a penny.
The short version
- The householder application fee is £548, but that's rarely the total cost
- Dartford has conservation areas, Article 4 directions, listed buildings, and Green Belt land that can all change what you need and what it costs
- Approval odds vary significantly by project type, street, and property — not just by borough
The fee you know about — and the ones you don't
The £548 covers submitting a standard householder application. If your application attracts a fee over £100 and you submit through the Planning Portal online, there's also a service charge of £75.83 + VAT on top. That's before you've paid for drawings, a planning consultant, or any specialist reports that may be required.
And if your application is refused? You don't get the fee back. If the council fails to decide within the statutory period, you can appeal — but appeals take time and often cost more than the original application.
Most homeowners don't realise how quickly the secondary costs stack up.
Dartford's constraints are more complicated than they look
Dartford has 6 conservation areas, 370 listed buildings, 6 Article 4 directions affecting specific streets, and Green Belt land covering parts of the borough. Each of these can completely change what you're allowed to do — and what it costs to find out.
In a conservation area, certain works that would normally be permitted development require a full application. That means fees you weren't expecting, and a scrutiny level you weren't prepared for. Article 4 directions remove permitted development rights on specific streets — but unless you know your street is affected, you won't know you need permission at all until it's too late.
Listed building consent is separate from planning permission and carries its own process. No application fee is required for listed building consent — but the professional costs involved in preparing a compliant application are a different matter entirely.
Don't assume your project is straightforward
Even a simple extension or loft conversion can trigger additional requirements depending on your postcode, your street, or the specific history of your property. What was approved next door may not apply to you.
Why approval odds matter as much as the fee
Here's what the fee calculator won't tell you: what are the chances your application actually gets approved? In Dartford, as in any borough, that varies enormously by project type and location. A rear extension in one DA1 postcode might sail through. The same project two streets away — inside a conservation area boundary or on an Article 4-affected road — might face objections, conditions, or outright refusal.
That's why WhatCanIBuild is the best way to understand your real position before you spend anything. It shows you what's been approved and refused for similar projects near your address, and how your property's specific combination of constraints affects your chances — not just whether you're in a conservation area, but what that actually means for your project.
The real cost of planning permission in Dartford isn't just the fee. It's the cost of going in blind.
Before you instruct an architect, submit anything, or assume your project qualifies for permitted development, WhatCanIBuild gives you a clear picture of what you're actually dealing with.
