The kitchen has overtaken every other room as the most-planned renovation project for 2026 — it's the room you use daily, and it tends to add more resale value per pound spent than almost anything else. But "kitchen renovation" can mean anything from a lick of paint on existing cabinets to a full structural rip-out, so the cost range is huge.
Here's what to actually expect at each level, where the money goes, and — most importantly — where kitchen budgets most commonly overrun.
Typical UK costs by scope
Repaint or reface existing cabinets, new worktop, new handles and hardware. Good if the layout works and the carcasses are sound. This is a fast-growing category — homeowners increasingly refresh rather than replace, both to save money and because well-built cabinets often don't need replacing at all, just updating.
New units, appliances and worktop, same layout and plumbing positions. This is what most homeowners mean by "full kitchen renovation." Keeping the sink and hob where they already are keeps costs down significantly — moving plumbing runs adds cost fast.
Open-plan knock-throughs, island additions, extending into a rear garden. This is where budgets most commonly balloon, because structural surprises — damp, unexpected joists, out-of-date wiring — tend to surface once walls come down.
Where the money actually goes
- Cabinets and units: 25–35% of total budget
- Worktops: 10–15% (natural stone and quartz sit at the top of this range)
- Appliances: 15–20%
- Labour (fitting, plumbing, electrics): 25–35%
- Flooring and tiling: 10–15%
What's trending for 2026
Kitchens are moving away from the all-white, all-grey look that dominated the last decade. Warmer, more textured palettes — olive, terracotta, deep clay tones — paired with natural wood are showing up in more renovation briefs this year. Smart appliances (touchless taps, voice-controlled ovens) are increasingly standard rather than a premium add-on, and zoned open-plan layouts — separating cooking, prep and entertaining areas rather than one big undivided space — are replacing the fully open-plan kitchens that dominated for years.
The single biggest reason kitchen budgets overrun
More than a third of homeowners renovating last year exceeded their initial budget, and the two biggest reasons were unexpected costs uncovered mid-project and homeowners upgrading their choices partway through — a nicer worktop, a better hob — once they'd already committed to the disruption. Both are avoidable with the same fix: set a realistic contingency of 15–20% on top of your quoted budget before you start, and track every invoice against it as you go rather than reviewing spend at the end.
Ask each contractor to itemise labour separately from materials on their quote. It makes comparing quotes far easier, and it's a useful early signal of how transparent a contractor will be to work with once the job starts.
Getting it right
- Get at least three quotes for any kitchen job over £5,000
- Set your contingency before you start — not after the first surprise
- Track spend by category so you can see you're 40% through your worktop allowance before you commit to the expensive slab, not after
- Match your spend to your property — a £30,000 kitchen in a £150,000 house rarely pays itself back
