Kitchen Extensions: What are you going to be paying in 2024?

A kitchen is one of the most versatile spaces in the house that can also serve as a central hub for friends and family to gather. So it is no surprise that a kitchen extension is among the most popular home improvements homeowners desire. But as with any extension project, there are a lot of questions and factors to consider as any of these can significantly impact the project's final cost.

The Basics Of Kitchen Extensions

A small kitchen extension can cost between £15,000 to £30,000 in the UK. Meanwhile, in London, the price jumps to about £50,000 for the same. A slightly more bespoke, high-quality kitchen extension can hit as hard as £100,000.

However, it is important to note that the numbers can widely vary based on the kitchen supplier, flooring type and finishes. A good guideline would be to consider a construction cost of £1,500 to £3,000 per square metre.

Size Matters When It Comes To Kitchen Extensions

You may be thinking about what classifies as a small kitchen extension. On average a 15m2 extension is considered small and anything up to 50m2 is large. The size of the extension can hugely dictate the labour costs and time frames. A generous 30m2 kitchen extension can take anywhere between 10 and 12 weeks to be completed by the builders.

If we further break down the numbers, the labour costs per day can be averaged at £150-200 per day, depending on the speciality of the tradesperson you are using.

Potential Further Costs For Kitchen Extensions

Now that you have a rough idea of how much a kitchen extension costs, there are other aspects to consider such as planning permission, Design service costs, floor risk assessment, etc. 

Planning permission isn’t always necessary but it’s worth checking the GOV and the council websites if you live in England and Wales. Planning application fees if required are usually around £200. Even if you don’t need planning permission, you may need a lawful development certificate of around £200. But these might not be the only costs. For example, you might have to do a flood risk assessment or an ecology report, which cost £600 and £720, respectively. Not to forget if your planned extension has an adjoining wall with a neighbour, you may need to fork out for a party wall agreement, which can cost up to £1000.

Summary For Kitchen Extension Costs


The cost of a kitchen extension is calculated on several different factors, like size, materials, location, and labour costs. Hopefully, this short guide gives you more of an idea of what to expect.
