How to Plan a Kitchen Renovation Step-by-Step in 2026 (UK)
A typical UK kitchen renovation in 2026 costs £15,000–£45,000 and runs 4–8 weeks on site — if it’s planned right. Plan it wrong and the same job overruns by 6 weeks and 30% on budget. The fix is sequencing: do all 9 steps below in this order before any trade starts on site.

The 9-step UK kitchen renovation plan (2026)
Step 1 — Set the realistic budget
2026 UK budgets: £15k–£22k for a mid-range refit (Howdens / Wickes-grade units, mid-range appliances); £22k–£38k for upper-mid (DIY Kitchens / Magnet, induction + integrated appliances, stone worktop); £38k–£65k+ for designer (Roundhouse, deVOL, Tom Howley). Add a 15% contingency on top — not 10%. Hidden plaster damage, wonky walls, asbestos in 1970s vinyl tiles — something always shows up.
Step 2 — Design the layout (before picking units)
The classic kitchen triangle (sink — cooker — fridge, each side 1.2–2.7 m) still applies. Walk the layout in tape on the floor first. If you’re moving the sink or hob to a new wall, factor in +£800–£2,500 for plumbing and electrics relocation.
Step 3 — Decide structural changes
Removing a wall? Get a structural engineer (£400–£900) for the beam calcs and submit a Building Notice to your council (or use an Approved Inspector). Add 1–2 weeks to the timeline.
Step 4 — Specify services (gas / electric / water)
2026 UK kitchens almost always need a consumer unit upgrade if the existing one predates 2018 (RCBO protection for the cooker circuit is now expected). Gas hobs are declining — about 70% of 2026 kitchen refits go induction. If you’re removing gas entirely, get the cooker point capped by a Gas Safe registered engineer.
Step 5 — Lock the appliance spec
Pick exact appliances before ordering units, because cabinet openings are cut for the model. Common slot widths: oven 60 cm, dishwasher 60 cm slimline 45 cm, fridge-freezer 70 cm American, 60 cm integrated. Lead times in 2026: Bora downdraft 8–12 weeks, Quooker 2–4 weeks, Miele oven 6–10 weeks. Order before the install slot, not after.
Step 6 — Book the trades in the right order
The sequencing matters more than picking the cheapest. Standard 2026 trade sequence:
- Strip out (1 day)
- Plasterer for ceiling/wall make-good (2–3 days)
- Electrician 1st fix — cable runs, sockets, lighting points (1–2 days)
- Plumber 1st fix — pipework, valves, waste runs (1–2 days)
- Plasterer skim (2–3 days, plus 5–7 days drying)
- Flooring (2–3 days)
- Kitchen fitter (5–10 days for units, worktops, splashback)
- Electrician + plumber 2nd fix — connect appliances (1–2 days)
- Painter + snagging (2–3 days)
Step 7 — Confirm lead times before booking the slot
2026 average lead times: Howdens flat-pack 1–2 weeks, DIY Kitchens 4–6 weeks, Magnet 6–10 weeks, Roundhouse / deVOL 14–20 weeks. Worktops: laminate same day, quartz/granite 3–5 weeks after templating. Book the fitter slot only after the units have a confirmed delivery date.
Step 8 — Manage the install on site
Have an empty calendar for the install weeks — you’ll need to be on site at 8 a.m. for delivery and at the end of each day to walk the work. Block a temporary cook-zone (microwave, kettle, hob plate) in another room. Most families lose 4–6 weeks of cooked dinners; budget £400–£800 for takeaways and ready meals.
Step 9 — Snagging
Walk the finished kitchen the day after install with a marked snag list: door alignment, drawer runners, sealant lines, plinth fit, appliance levelling. Standard 2026 retention is 5% of the kitchen fitter fee, held back until snags are signed off. Don’t pay the final invoice without a written snag-resolution sign-off.
The 4 biggest cost traps in 2026
- Forgetting Building Control — any wall removal needs Building Notice (£200–£400 council fee). Skipping it voids the future buyer’s solicitor sign-off.
- Picking units before appliances — you end up with the wrong oven slot and a £1,500 cabinet rework bill.
- No contingency — the “just plaster the kitchen wall” scope creep turns into the whole ceiling.
- Cheapest fitter, not best-sequenced fitter — a cheap fitter who skips the 1st-fix walk-through delays every trade behind them.
Before you sign: the 2026 kitchen contract checklist
Most kitchen disputes trace back to what was never written down. Before you sign a fitter’s contract in 2026, confirm every line below in writing — it is the cheapest insurance you will ever buy. For a fuller walk-through of comparing quotes, read our guide on how to hire a trusted kitchen fitter.
- Fixed price vs day-rate — a fixed price against a written spec protects you from scope creep; day-rate suits only very small jobs.
- Stage-linked payments — never pay more than 25% up front; release the balance against completed 1st-fix, install and snagging milestones.
- Who supplies the units — retailer-supplied or fitter-supplied decides where the warranty sits if a door or carcass fails.
- VAT status — a standard kitchen refit carries 20% VAT; confirm whether the quoted figure includes or excludes it before you compare bids.
- Making-good and waste removal — skip hire and old-kitchen disposal should be named in the quote, not assumed.
- Guarantee and snag retention — hold back 5% of the fitter fee until the written snag list is signed off.
To sanity-check where your money goes per square metre before briefing anyone, compare your quotes against the average cost of a kitchen refit per m².
