FAQs

  • How much does a kitchen extension cost in the UK?

  • The cost of a kitchen extension can be between £20,000 and £60,000 + VAT, depending on the size of your extensions and the materials you choose. There’s no set price when it comes to the cost of kitchen extensions, however, and you may find that you pay more or less depending on where you live and who you employ to get the job done.

  • How much does a single story kitchen extension cost UK?

  • A kitchen extension can cost between £1,200 and £1,500 + VAT per square metre in the UK. Rear extensions tend to be cheaper, costing around £20,000 + VAT on average, whereas wraparound extensions can cost upwards of £40,000 + VAT dependent on how big the project is.

  • Do you need planning permission for a single storey kitchen extension?

  • You need planning permissions for a single storey kitchen extension if you are planning on extending the rear wall of your house by more than three meters if semi-detached, or four metres if detached. If your single-storey extension exceeds four metres and is more than half the area of land around the "original house", then you’ll also need planning permission.

  • What is the most expensive part of building an extension?

  • The most expensive parts of building an extension are usually the roofing and the foundation, as building these requires the most manpower and time. Building a two-storey extension can offer better value to those with the funds who are willing to maximise the space in their home.

  • What are the benefits of a kitchen extension?

  • Kitchen extensions offer several benefits, including increased living and storage space, improved functionality, enhanced natural light, the opportunity for open-plan living, and the ability to create a bespoke kitchen layout.
