Kitchen Renovation Cost Guide UK 2025
The kitchen is the most financially significant room in any home renovation. It's also the one most likely to run over budget, because the range of choices — from flat-pack carcasses to hand-painted in-frame joinery — spans two orders of magnitude in cost. A realistic understanding of what drives kitchen renovation costs is the most useful thing you can have before you start talking to suppliers or designers.
The Four Budget Levels
Budget Refresh: £3,000–£8,000
A budget refresh replaces units, worktops, and possibly appliances without moving plumbing, electrics, or walls. This is the swap-like-for-like approach: the same footprint, new faces.
- Flat-pack or rigid carcasses from IKEA, B&Q, or Howdens
- Slab-style doors (MDF, foil-wrapped, or painted)
- Laminate or budget timber worktop
- Standard integrated appliances (dishwasher, fridge-freezer, oven, hob)
- Existing plumbing connections retained
- DIY or basic fitter installation
Best for: rental properties, short-term homes, or where the layout works and only the aesthetics are dated.
Mid-Range: £10,000–£20,000
This is the most common kitchen renovation bracket for UK homeowners. It allows for better-quality units, a proper worktop upgrade (quartz, granite, or solid wood), and often some minor changes to the layout.
- Rigid-build carcasses (better than flat-pack, longer lifespan)
- Shaker or handleless doors in paint or vinyl
- Quartz or granite worktops (£200–£400/m²)
- Mid-range appliances (Bosch, Siemens, Smeg)
- Possible minor plumbing repositioning
- Professional installation by specialist kitchen fitter
Premium: £25,000–£50,000
At this level, you're typically working with a kitchen designer, specifying bespoke or semi-bespoke units, and potentially altering the room's structure — knocking through to a dining room, adding a kitchen island, or improving glazing.
- Semi-bespoke or bespoke units with soft-close hardware, pull-out drawers throughout
- In-frame construction (more expensive, more rigid, traditional aesthetic)
- Quartz, granite, or hardwood worktops, often with matching upstands or splashbacks
- High-end appliances (Miele, Gaggenau, AEG)
- Underfloor heating (£800–£2,000 additional)
- Structural wall removal with RSJ (£2,000–£6,000 additional, including building regs)
Bespoke: £60,000+
Bespoke kitchens are hand-crafted to measure by specialist manufacturers (Neptune, deVOL, Humphrey Munson, Mark Wilkinson). Lead times of 12–20 weeks are normal. At this level, the kitchen itself is often a smaller proportion of total cost — premium appliances, stone floors, bespoke lighting, and architectural changes add up fast.
What Drives Cost
In-frame vs slab-door construction. In-frame kitchens (where the door sits within a solid timber frame) cost 30–60% more than equivalent slab-door designs. They're more rigid and have a traditional appearance. For most mid-range kitchens, the premium is hard to justify on structural grounds.
Worktop material. The worktop decision alone can move your budget by £3,000–£8,000:
- Laminate: £30–£80/m² — durable, low-maintenance, not premium-feeling
- Solid timber: £100–£250/m² — beautiful, needs regular oiling, susceptible to water damage around sink
- Quartz composite: £200–£400/m² — non-porous, very durable, wide colour range, can chip at edges
- Granite: £200–£450/m² — natural variation, extremely durable, porous (requires sealing)
- Dekton / porcelain: £300–£600/m² — heat and scratch resistant, expensive to fabricate and fit
Moving the sink. Repositioning the sink means extending or rerouting soil pipes and waste runs. In a standard terrace, this costs £800–£2,000 including plumber time, chasing out walls, and making good. If the kitchen is above a ground floor slab rather than suspended timber, the cost increases significantly.
Removing a wall. Opening the kitchen into a dining room or living space typically requires installing a steel beam (RSJ) to carry the load above. Including structural calculations, building control fees, steel supply and installation, padstones, and making good, budget £2,500–£6,000 for a standard single-skin internal wall removal.

DIY vs Trade: What You Can Safely Do Yourself
Safe to DIY (if competent):
- Painting walls and ceilings
- Fitting flat-pack or rigid carcasses (with care for level and plumb)
- Tiling splashbacks (not immediately adjacent to gas hobs or over complex substrates)
- Fitting worktops (laminate and timber, not stone which requires specialist tools)
- Painting unit doors
Trade-only (legal requirement or safety-critical):
- Any gas work — Gas Safe registered engineer only
- Notifiable electrical work under Part P: installing a new circuit, consumer unit work, any work in a kitchen within 300mm of a sink or water supply
- Structural work involving load-bearing walls
- Plumbing connections to soil pipes
Planning Permission and Building Regulations
An internal kitchen renovation — however extensive — does not require planning permission. No application is needed unless you're extending the building.
Building Regulations do apply, however:
- Part P (Electrical safety): Any new circuit installed in a kitchen requires either a Building Control application or a certificate from a registered Part P electrician (NICEIC or NAPIT). Replacing a like-for-like socket on an existing circuit is not notifiable.
- Part A (Structure): If you're removing any load-bearing wall, structural calculations and building control approval are required.
Project Timeline
| Budget Level | Planning Phase | Installation | Total |
|---|---|---|---|
| Budget refresh | 1–2 weeks | 2–5 days | 2–3 weeks |
| Mid-range | 4–6 weeks | 1–2 weeks | 6–8 weeks |
| Premium | 8–16 weeks | 2–4 weeks | 10–20 weeks |
| Bespoke | 12–24 weeks | 3–5 weeks | 16–28 weeks |
Getting Accurate Quotes
Write a scope of works. Before approaching any supplier or fitter, document: the kitchen dimensions, what you're keeping, what you're removing, whether any walls are moving, where the sink and appliances will sit, and your material preferences. This ensures you receive comparable quotes.
Get three quotes minimum. For installation work (fitters, plumbers, electricians), obtain at least three quotes on an identical scope. A quote that is 30% below the others is not a bargain — it's a question mark.
Watch for variation clauses. Some kitchen fitters quote a supply-only price and then bill separately for installation. Others include a day-rate clause that allows them to charge for unforeseen work (discovering old pipework, concrete floors, damp walls) without a cap. Any good contract should define a variation procedure and require written approval before additional costs are incurred.
VAT
All labour and materials for a kitchen renovation are subject to 20% VAT in standard circumstances. There is no reduced rate for kitchen works in an occupied dwelling. The 5% reduced rate for construction work only applies to certain qualifying conversions, renovations of long-empty properties, and some residential conversions — not to standard internal renovation of an occupied house. Listed building owners may benefit from zero-rating on some works — take specialist VAT advice.
Top 3 Mistakes Homeowners Make
1. Ordering units before confirming exact measurements. Fitted kitchens are made to measure. If your builder finds the walls aren't square (common in older properties), units ordered to nominal dimensions won't fit. Always measure after any structural or plastering work is complete.
2. No contingency for unforeseen plumbing and electrics. When you pull out old units, you'll discover the previous owner's DIY plumbing and wiring. Set aside 10–15% of your budget for genuine contingency — not just a notional figure.
3. Choosing appliances last. Integrated appliances (dishwashers, fridges, ovens) have specific housing dimensions that must be built into the unit specification. Leaving appliance decisions to the end of the design process means late changes to cabinets, which cost money.
