There are two key factors to consider when looking at the cost of a kitchen extension, the price of the building work involved in the extension itself, and the cost of the new kitchen. These can all be done as part of the same project by the same team of general builders, or carried out separately afterfinding specialist extension buildersfollowed by kitchen fitters.
Speaking to our experts, we have established that the basic price of building an extension is £1,100 to £1,400 per square metre. So, for a 20msq extension (4m x 5m), the cost will range from £22,000 to £28,000. These prices don’t include VAT, charged at 20%. The price bracket reflects the variance of materials used, the complexity of design, quality of finish and where in the UK you live. This price covers the essential elements of the build, constructing the foundations, building the walls, insulating the new structure, fitting out with plasterboard, adding a subfloor, and installing a basic provision for plumbing and electrics.
The kitchen element will depend on the quality and the materials you wish to use, and the size of the kitchen being installed - the number of units you will need, and the size of the work surfaces for example. After speaking to experienced MyBuilder.com tradespeople around the UK, we estimate that the average price of a new kitchen installation in the UK costs around £5,000 to £6,000. At the lower end of the spectrum, it can be possible to purchase and install a new kitchen from around £1,200. At the high end, the price can be limitless depending on your specifications, but a top of the range kitchen may cost around £14,000. Prices will generally be higher in London and the south east where tradespeople can charge a premium for their time.
In total then, the average cost of a kitchen extension will be around £30,000.

MyBuilder Top Tip
At MyBuilder, we tend to advocate for hiring specialists in their particular fields to help make sure a job is done well. When constructing a kitchen extension, you may want to hirekitchen fittersseparately from the firm that builds the extension, particularly if it’s a high-end kitchen which requires particular skill and attention to fit and working with specialist materials such as a granite or marble. However, an experienced extensions firm may be able to carry out the entire job from start to finish - make sure you ask to see examples of their previous work so you’re happy that they are up to scratch.
