House Extension Planning Permission in
Leatherhead (Surrey)

Not every house extension in Leatherhead needs full planning permission – a lot of straightforward single-storey rear extensions fall under permitted development, some qualify for the faster 42-day Prior Approval route, and others genuinely need a full application. Our free desktop study tells you exactly which applies before you commit to anything.

The Real Picture For Leatherhead Extensions

Leatherhead’s planning authority, like every council, has to work within national permitted development rules, but local factors – conservation area status, Article 4 directions, existing extensions on the property – all affect what’s actually available to you here specifically.

A generic online guide can tell you the national rules, but it can’t tell you whether your specific Leatherhead property still has its permitted development rights intact, or whether a previous owner’s extension has already used up the allowance. That’s exactly what our desktop study establishes.

Rather than assuming permitted development applies or automatically preparing a full application, we start every Leatherhead enquiry with a genuine assessment of what your specific project actually requires.

How We Help in Leatherhead (Surrey)

For Leatherhead properties, we start by working out the actual picture – existing extensions, conservation status, and exactly what your proposed extension would involve – before recommending anything.

Once that’s clear, your Leatherhead project gets exactly what it needs, whether that’s confirmation permitted development already covers it, a Prior Approval submission, or a full application prepared to what this specific council expects.

Once anything’s submitted for a Leatherhead project, we follow it through properly – staying in contact with the council and responding to queries as they arise.

Why Leatherhead Homeowners Start With A Desktop Study

Generic online guidance can’t account for Leatherhead’s local specifics or your property’s individual planning history. We check the real picture before recommending anything, rather than applying a one-size-fits-all rule.

We’d rather tell you honestly that your Leatherhead extension doesn’t need planning permission at all than take a fee for an application that was never required. That honesty is the whole point of the desktop study.

We’d rather give you the complete, accurate picture of your Leatherhead project upfront – including where it’s a genuine mix of routes – than a simplified answer that misses something important.

House Extension Planning Permission FAQs for Leatherhead

What are the permitted development limits for an extension in Leatherhead?

Standard single-storey rear extensions can usually go up to 3 metres (terraced/semi-detached) or 4 metres (detached) without planning permission, with larger extensions up to 6-8 metres possible under the Prior Approval route – your desktop study confirms exactly what applies to your Leatherhead property.

What is Prior Approval and does my Leatherhead extension qualify?

Prior Approval is a faster route (42 days rather than the usual 8 weeks) for larger single-storey rear extensions that exceed standard permitted development limits but stay within extended ones – your desktop study checks whether your Leatherhead project qualifies.

Are permitted development rights different in Leatherhead conservation areas?

Yes – conservation area status in Leatherhead typically removes some permitted development rights, particularly for side extensions and cladding, meaning full planning permission is more often required.

Does a previous extension affect what I can do now in Leatherhead?

Possibly not – permitted development allowances are cumulative, so a previous owner’s extension in Leatherhead may have already used up some or all of what’s available to you now.

Is it common for Leatherhead projects to need a mix of routes?

Yes, this happens regularly with larger or more complex Leatherhead projects – one element might fall under permitted development while another genuinely needs full permission, and we identify exactly which is which.

How much does the desktop study cost for a Leatherhead extension?

Yes, the desktop study is free for Leatherhead enquiries – you’ll know exactly what your project needs before committing to anything further.
