kitchen renovation cost

Quick Answer: A complete kitchen renovation in the UK typically costs between £8,000–£25,000+ depending on size and specification. Plan for 4–8 weeks of work including demolition, first fix (plumbing, electrics), plastering walls and ceilings, second fix (units, worktops), and finishing. The key to success is detailed planning, realistic budgeting (add 15–20% contingency), and coordinating trades in the correct sequence. Why Kitchen Renovations Require More Planning Than Other Rooms Your kitchen isn’t just another room — it’s the operational heart of your home. Unlike a bedroom or lounge where you might get away with a simple redecoration, a proper kitchen renovation involves multiple trades working in precise sequence, strict adherence to Building Regulations, and careful coordination of services. From a plasterer’s perspective, kitchens present unique challenges. You’re working around new plumbing runs, rewired electrics, extractor ductwork, and potentially structural changes where walls have been removed or openings widened. Get the plastering stage wrong, and it affects every trade that follows. Modern kitchen renovations in 2026 also need to address energy efficiency requirements under Building Regulations Part L. If you’re removing walls or adding extensions, you’ll need to demonstrate improved thermal performance — often meaning insulated plasterboard becomes part of your specification rather than an optional upgrade. The True Cost of Kitchen Renovation in 2026 Let’s break down realistic costs based on current UK pricing. These figures reflect actual contractor quotes in Kent and Southeast England as of early 2026, including materials and labour. Kitchen Type Size Typical Cost Range Duration Budget Refresh Small (8–10m²) £5,000–£8,000 2–3 weeks Standard Renovation Medium (10–15m²) £12,000–£18,000 4–6 weeks Premium Remodel Large (15–20m²) £20,000–£30,000 6–8 weeks Luxury Kitchen Large (20m²+) £30,000–£50,000+ 8–12 weeks These ranges include all trades — demolition, building work, plumbing, electrics, plastering, flooring, units, and worktops.

What Affects Kitchen Renovation Pricing Structural changes: Removing walls, creating openings, or adding steel beams adds £2,000–£8,000 to your budget Services relocation: Moving gas, water, or drainage runs costs £800–£2,500 per service depending on distance Kitchen unit quality: Flat-pack from Wickes (£2,000–£4,000) versus bespoke cabinetry (£8,000–£15,000+) Worktop material: Laminate (£150–£300), solid wood (£400–£800), quartz/granite (£1,200–£3,500+) Appliance specification: Budget package (£1,500–£2,500) versus premium brands (£5,000–£10,000+) Flooring choice: Vinyl (£20–£35/m²), porcelain tiles (£40–£80/m²), engineered wood (£50–£90/m²) Pro Tip: Always add a 15–20% contingency to your kitchen budget. Once walls come down, you invariably find issues — damp patches needing treatment, outdated wiring requiring full rewire, or floors that aren’t level and need screed. I’ve yet to complete a kitchen renovation that didn’t uncover at least one unexpected problem requiring additional work. The Complete Kitchen Renovation Timeline Understanding the sequence of work helps you plan realistically and coordinate trades effectively. Here’s the professional timeline for a typical medium-sized kitchen renovation: Phase 1: Strip Out and First Fix (Week 1–2) Days 1–3: Demolition and strip out. Old units removed, appliances disconnected, tiles stripped from walls. If you’re removing walls, this happens now — with proper structural calculations and Building Control notification for load-bearing walls. Days 4–10: First fix trades. Plumber runs new pipework, electrician installs new circuits and moves sockets, gas engineer relocates boiler or hob supply. Plasterers can’t start until all services are first-fixed and chased into walls. Phase 2: Plastering and Making Good (Week 2–3) Days 11–13: Wall preparation and plastering. This is where we come in. Chase lines are filled, walls prepared with bonding coat if needed, then skim coated with finishing plaster. For kitchen walls, we typically use Thistle Multi-Finish which provides a harder, more durable surface than standard board finish. On external walls or those prone to condensation, we’ll spec insulated plasterboard (typically 50mm+ Celotex or Kingspan bonded to 12.5mm British Gypsum board) to meet thermal regulations and prevent mould growth behind units. Days 14–16: Drying time. This is non-negotiable. Fresh plaster needs 7–14 days to dry fully before painting or tiling, depending on conditions. You can speed drying with gentle heat and ventilation, but never rush it — trapped moisture causes paint to bubble and tiles to fail. For detailed information on plaster drying times and what affects them, see our guide on how long plaster takes to dry. Phase 3: Second Fix and Installation (Week 3–5) Days 17–20: Flooring installation. Goes down before units to provide a level base and allow you to move units around if needed. Porcelain tiles need 24–48 hours to cure before walking on them. Days 21–28: Kitchen units fitted. Base units installed first, levelled carefully, then wall units hung. Worktops templated and fitted (stone worktops need a separate visit for templating, then 7–10 days fabrication time). Days 29–32: Appliances and second fix. Sink connected, hob wired in, tiling completed around worktops, electrician fits faceplates and lights, decorator applies mist coats to fresh plaster and final paint. Phase 4: Finishing (Week 5–6) Days 33–35: Snagging and finishing. Silicon seals applied around worktops and sinks, handles fitted to units, touch-up painting completed, final appliances installed and commissioned. ⚠️ Warning: Never allow kitchen fitters to install units against fresh plaster that hasn’t fully dried. The moisture will be trapped behind units and cause mould, bubbling paint, and potential unit damage. Minimum 7 days drying time, ideally 10–14 days in winter months. Planning Permission and Building Regulations Most kitchen renovations fall under permitted development and don’t require planning permission. However, Building Regulations approval is mandatory for: Removing or altering load-bearing walls (structural changes) Moving or installing new gas appliances Significant electrical work (new circuits, consumer unit changes) New drainage or modifications to existing waste systems Windows or external doors that affect thermal performance Your electrician must be registered with a Competent Person Scheme (NICEIC, NAPIT, or equivalent) to self-certify electrical work. Gas work must be done by a Gas Safe registered engineer. For structural work, you’ll need calculations from a structural engineer and Building Control sign-off. In 2026, new builds and major renovations must achieve higher energy efficiency standards under the updated Part L. This
