Do I need planning permission in City of London?

Planning permission in the City of London isn't just complicated — it's a different league entirely. The combination of factors that apply here means that what's straightforward elsewhere in the UK can become a minefield before you've even picked up a phone. WhatCanIBuild exists precisely for situations like this — where the answer to "do I need permission?" is almost never a simple yes or no.

The City of London is not like other boroughs

The City of London Corporation manages one of the most commercially dense and historically sensitive areas in the country. Almost every street falls within a conservation area. That's not a minor footnote — it changes what you can do to your property in ways most homeowners don't anticipate. And it's not just about listed buildings, though there are plenty of those too.

Article 4 directions add another layer. These are specific instructions that remove what would normally be permitted development rights — rights that would elsewhere allow you to make certain changes without applying for planning permission at all. In the City of London, Article 4 directions are extensive. Whether they apply to your property, and exactly what they remove, depends on your specific address.

"Permitted development" may not apply the way you think

Most people have heard that some home improvements don't need planning permission — they're covered by permitted development rights. What most homeowners don't realise is how easily those rights can be stripped away. In areas with Article 4 directions, changes you'd assume were fine — things that would sail through anywhere else — can require a full planning application.

In the City of London, assuming you have permitted development rights is a risk. Whether you do depends on your property's specific designation, its position on the street, what's happened to similar properties nearby, and a combination of overlapping constraints that aren't visible without checking.

The fee is just the beginning

A householder planning application in the City of London costs £258. But the fee is the least of your concerns if you submit without understanding what's likely to be approved. The City of London has a distinct character, a demanding set of heritage considerations, and a planning authority — the City of London Corporation — that takes both seriously. What's been approved and refused on your street, and why, matters enormously. It affects your chances before you've written a single word of a planning statement.

That's the kind of insight that changes whether you apply, how you apply, and whether it's worth it — and it's not something you can piece together from a general guide.

The best way to know what applies to your property

The best way to understand your position isn't to read more articles. It's to check your specific address against everything that actually applies to it. WhatCanIBuild tells you what's been approved and refused nearby, what your property's combination of constraints actually means in practice, and what your approval odds look like for your specific project — not just whether you're in a conservation area, but what that conservation area status has meant for properties like yours.

Guessing is risky. Getting it wrong is expensive. If you're making changes to a property in EC1–EC4, the stakes are higher than almost anywhere else in the country.

WhatCanIBuild gives you a clear picture based on your address — not general rules that may not apply to you at all.
