When thinking about enhancing your home, extending your kitchen can be one of the most rewarding upgrades. Not only does it give you more functional space, but it can also significantly increase your home’s value. However, a common question is: “How much does a kitchen extension cost?” The truth is, the costs can vary widely based on your design choices, location, and the scope of work. To help guide you through, we’ve put together this 2024 guide on kitchen extension costs, outlining what you can expect from start to finish.
There’s a range of factors that influence the cost of extending your kitchen, so it’s important to be aware of them before starting. Here are the key ones:
The bigger the extension, the more you’ll pay. But it’s not just about size. A basic, simple design will cost less compared to a more complex layout featuring bespoke cabinetry, skylights, and luxury finishes.
Materials play a huge role in the overall cost. Standard materials like uPVC windows and standard brickwork are more affordable, whereas bi-fold doors, marble worktops, or reclaimed wood flooring will push up the price.
If your extension involves removing structural walls or adding steel beams for support, this will increase the cost. Structural engineers may need to be involved, and unexpected issues, such as poor foundations or damp, could escalate the budget.
In London and the South East, tradesmen’s fees are typically higher than in other parts of the UK. Skilled builders, electricians, and plumbers charge a premium due to the high demand in these areas.
If your extension requires planning permission or structural calculations – which is most cases – you’ll need to factor in these costs too. Most kitchen extensions fall under permitted development rights, but it’s always wise to double-check with your local council.
