The 10 Biggest Kitchen Renovation Mistakes

1. Underestimating the budget — Always add 15–20% contingency. Hidden issues like damp, uneven floors or outdated electrics can add thousands.

2. Ignoring the work triangle — The sink, hob and fridge should form an efficient triangle for workflow.

3. Skimping on storage — More storage is almost always better. Think about pan drawers, corner solutions and wall-mounted options.

4. Choosing style over function — Open shelving looks great in magazines but collects dust and grease.

5. Poor lighting planning — Layer your lighting: task lights under cabinets, ambient ceiling lights and accent lighting.

6. Not hiring the right tradespeople — A kitchen fitter, electrician and plumber each have specialised skills. Do not assume one person can do it all.

7. Forgetting about ventilation — A good extractor hood is essential, especially in open-plan layouts.

8. DIY on electrics and gas — Electrical and gas work must be done by certified professionals (Part P and Gas Safe).

9. Choosing worktops too early — Worktops should complement the overall design, which may evolve during the project.

10. Not getting enough quotes — Get at least 3 quotes and check reviews before hiring.

How Much Does a Kitchen Renovation Cost?

Budget kitchens start from £5,000–£8,000, mid-range renovations cost £10,000–£20,000, and high-end kitchens can reach £25,000–£50,000+. The biggest costs are usually the units, worktops and installation labour.

Frequently Asked Questions

How long does a kitchen renovation take?
A straightforward kitchen renovation typically takes 2–4 weeks from strip-out to completion. More complex projects involving structural changes, new electrics or plumbing can take 6–8 weeks.
Do I need planning permission for a kitchen renovation?
Generally no — internal renovations do not require planning permission. However, if you are extending the kitchen, adding structural openings or the property is listed, you may need permission from your local planning authority.
Should I hire a kitchen fitter or a builder?
For a standard kitchen installation, a specialist kitchen fitter is usually the best choice. If your renovation involves structural work (removing walls, extensions), you will also need a builder. On TradeMatch, you can find both and compare quotes.
