Costs for kitchen extension
A kitchen extension involves a lot of work: the cost of specialists, materials and, of course, choosing the kitchen. Fortunately, it is possible to keep the costs under control, such as picking a cheap kitchen, having the extension delivered as shell and by comparing quotations.

Price examples
In the previously mentioned price table you can see an overview of average prices. Below are examples that explain the prices in more detail.
Most chosen work
The most chosen work is usually easily the most economical. This is because people often opt for a shell kitchen extension. If you assume 2.5 (l) x 2.5 (h) metres, 3 walls with door and window frames, flat roof and standard bricks, you arrive at an average price of £8,000 for the extension.
Greater project
A larger project includes everything. This includes costs for finishing, electricity, gas, water, sewage, floor, walls, ceiling and kitchen. So you hand everything over so you can be sure that the project will be completed 100 per cent of the time. Do you opt for a hull extension with the above-mentioned finishes? Then you come to an average price of £20,000.

What choices affect the price of your kitchen extension?
When building an extension for your kitchen, the price is determined by 4 choices.
Choice 1: Size of extension
A kitchen extension can still vary in width and depth. If you have a kitchen extension installed at the back of your house and still want to enjoy your garden to the full?
- Width: Per half a metre, an average price of £1,000 is added.
- Depth: For half a metre more or less depth, an average price of £1,250 is charged.
Choice 2: Prefabricated or customised kitchen extension?
A second choice is the difference between a prefabricated and a customised extension. Prefabricated extensions are made in the factory and brought to site. This makes prefabricated more economical. With a prefabricated extension, there are fixed dimensions to choose from. These dimensions are common dimensions so chances are your dimensions are among them. With made-to-measure, you have the possibility to apply your wishes to the kitchen extension. So take a good look at how much money you have to spend and then decide. A prefabricated extension is on average £2,000 cheaper than a custom-made one.
Choice 3: The type of kitchen
The type of kitchen is also an important choice for an extension. Will you leave the kitchen in place or opt for a total change. You can make it as expensive as you want. See below what the average costs are for the activities in and around the kitchen.
