If you are considering extending your kitchen in London, one of the first questions that may arise is whether or not you need planning permission. At Vector Living, we specialise in helping homeowners navigate these questions and deliver high-quality extensions that transform how homes function. As a trusted kitchen extension builder with a track record across London, Surrey, and Hampshire, we offer end-to-end solutions that include planning, design, construction, and compliance management.
Do Kitchen Extensions Require Planning Permission in London?
In many cases, you can build a kitchen extension under what’s known as “Permitted Development Rights.” This means you don’t need formal planning permission, provided your project adheres to specific rules regarding size, height, boundary distance, and materials. However, many London homes fall within conservation areas, have previously been extended, or are flats – all of which may require full planning consent.
As an experienced kitchen extension builder, Vector Living supports you through this process. Our in-house team handles all planning applications and liaises with local authorities to ensure a smooth and timely approval.
What Is Permitted Development and How Does It Apply?
Permitted Development Rights allow certain types of work to be carried out without needing a full planning application.
In terms of kitchen extensions, the key criteria include:
Single-storey rear extensions up to 3m (semi-detached or terraced homes)
Extensions up to 4m for detached homes
Maximum height of 4m
No more than half the land around the house can be covered
Materials must be similar to the existing property
If your home is in a conservation area such as Notting Hill, Hampstead, or parts of Richmond, additional restrictions may apply. Listed buildings always require full planning permission.
Vector Living's in-depth knowledge of local planning departments ensures we can advise quickly and accurately on what permissions your extension will require.
When Full Planning Permission Is Required
There are scenarios where full planning permission will be needed:
If you are planning a two-storey or wraparound extension
If your extension will be closer to the boundary than allowed
If your property has already been extended beyond Permitted Development limits
If you live in a flat or maisonette
If your property is in a conservation area or is listed
In these cases, having a kitchen extension builder like Vector Living on your side becomes invaluable. We submit plans, respond to planning officer queries, and coordinate any required reports or heritage assessments.
Kitchen Renovation London: Combine Layout Improvements with Your Extension
Many clients use the opportunity to carry out a complete kitchen renovation London homeowners often crave.
This might include:
Removing walls to create open-plan spaces
Adding bi-fold or sliding doors for more natural light
Installing bespoke kitchen cabinetry
Adding a scullery or utility space for improved functionality
In Flo’s complete house renovation in Twickenham, we combined a rear extension with a full kitchen and bathroom upgrade. As Flo said, “Working with Vector Living and Ash has been just so easy. We would definitely recommend to other families in the area.”
Whether you're adding space for entertaining, modernising an outdated layout, or planning a kitchen diner extension in a narrow London terrace, we ensure all building regulations and planning conditions are met.

FAQ: Kitchen Extension Builder and Planning Permission in London
Do I need planning permission for a single-storey kitchen extension in London?
In many cases, no – provided it falls within Permitted Development guidelines. However, properties in conservation areas or flats will usually need permission. Vector Living handles all planning requirements for you.
What’s the difference between Permitted Development and Planning Permission?
Permitted Development covers minor works that meet set rules. Planning permission is required for projects outside those rules, such as large extensions, work on listed buildings, or construction in conservation areas.
How long does it take to get planning approval in London?
On average, 8 to 12 weeks from submission. Our team helps speed up the process by preparing accurate applications and responding to local authority queries.
Can I renovate my kitchen at the same time as the extension?
Yes. Combining a kitchen renovation with your extension project is more efficient and ensures a cohesive design. We regularly carry out kitchen renovation London projects alongside extension builds.
Do you handle all paperwork and building regulations?
Yes. Vector Living manages planning submissions, building control approvals, and all compliance documentation from start to finish.hire.
