Most homeowners in Hackney start by googling the application fee and assume that's the answer. It isn't even close. The real cost of planning permission depends on your property, your street, and a set of local conditions that aren't obvious until something goes wrong — WhatCanIBuild exists precisely because those variables are so hard to untangle on your own.
The short version
- The standard householder planning application fee in Hackney is £258
- That figure doesn't include professional fees, potential re-submissions, or the cost of getting it wrong
- Hackney has conservation areas, Article 4 directions, and other constraints that can change what's possible on your property entirely
The £258 figure is just the beginning
Yes, the householder application fee in Hackney is £258. If you submit through the Planning Portal online, there's also a service charge of £75.83 + VAT on top of that for applications attracting a fee over £100. So already you're spending more than the headline number suggests.
But that's before you've paid anyone to draw up plans, write a supporting statement, or respond to queries from the council. Most homeowners don't realise that architects, planning consultants, and drawing fees can dwarf the application fee itself — and none of that is standardised or predictable without knowing exactly what your project involves.
And if the council doesn't approve first time? You're looking at re-submission costs, delays, and potentially starting from scratch.
What most homeowners in Hackney don't account for
Hackney is one of the most constrained boroughs in London when it comes to planning. There are conservation areas around Dalston, De Beauvoir, Clapton, and elsewhere. Article 4 directions apply across several of these areas. If your property sits within one of them, work that would be straightforward elsewhere might require a full application — and carry a meaningfully different chance of approval.
Most homeowners don't realise their address puts them in this category until they're already mid-project.
Then there's the question of what's actually been happening on your street. Have similar extensions been approved nearby? Have any been refused, and why? That history matters enormously to how your application will land — and it's not something you can easily piece together yourself.
Don't assume permitted development applies
Even projects that look like they don't need planning permission can require it in Hackney, depending on your specific property's designations. Permitted development rights can be restricted by Article 4 directions without any visible sign at your address.
The cost of getting it wrong
There's no refund if your application is refused. There's no refund if you submit the wrong application type. Typical decision time in Hackney is around 8 weeks — so a mistake doesn't just cost money, it costs months.
The best way to understand what applies to your property isn't to read the general rules — it's to look at your specific address against Hackney's actual planning record. WhatCanIBuild shows you what's been approved and refused for similar projects near you, what constraints affect your property, and what that combination actually means for your approval odds — not in general, but for your project type in your part of Hackney.
That's the information that changes what you spend, how you prepare, and whether you go ahead at all.
Before you budget, check your property
The £258 application fee is real. Everything on top of it — professional costs, re-submissions, delays — depends entirely on variables that are specific to your address. WhatCanIBuild gives you a clear picture of what you're actually working with before you spend a penny.
