Kitchen Renovation Timeline (UK): The Two Timelines Most Homeowners Don't See

Last updated: 11 June 2026 · By Mossy Tariq, Founder — Property Blueprint Co.

Ask a homeowner how long their new kitchen will take and they will give you the fit time — the couple of weeks the fitters are on site. Ask the kitchen fitter who has run a hundred of them and they will give you a different number, usually two or three times larger, because they are counting the weeks the homeowner never sees: the units sitting in a warehouse on a lead time, the worktop template that cannot be taken until the units are in, the plaster that has to dry, the structural sign-off that has to come through before a wall comes down.

That gap — between the time the work takes and the time the project takes — is where almost every kitchen renovation timeline goes wrong. The fit is the short, visible part. The procurement, the worktop fabrication, and the drying time around it are the long part, and they are the part nobody puts on the calendar.

This sets out both timelines for a standard UK kitchen renovation, so the prepared homeowner plans to the elapsed time the project really needs, not the fit time it appears to take.

A kitchen renovation has two timelines: the days the fitters work, and the weeks the suppliers, the worktop, and the plaster decide.

Get the two confused and every date you give your family, your trades, and yourself is wrong from the first week. The on-site sequence below follows the same logic as the order of trades in a kitchen renovation — but the timeline is where the off-site weeks get counted in.

Why a kitchen renovation has two timelines, not one

The working timeline is the number of days a trade is physically on site. The elapsed timeline is the number of days from the moment you decide to renovate to the moment the kitchen is finished and signed off. Those two numbers are far apart in a kitchen, because the longest delays happen when no trade is on site at all — while units are being made, while a worktop is being cut, while fresh plaster dries.

A typical kitchen carries only ten to fifteen working days of trades, yet runs six to twelve weeks of elapsed time once procurement, the worktop gap, and drying time are counted. The homeowner who plans to the fifteen days is the one who cannot understand why, two months in, the kitchen is still not usable. The same logic that governs the twelve phases of a renovation applies here, with the calendar stretched by everything that happens between the phases.

The working timeline: how long the fit actually takes

These are the on-site stages of a standard kitchen renovation and the working time each typically takes once it starts. These are labour days, not elapsed days — the gaps between them are counted in the next section.

1. Strip-out (1–2 days). The old kitchen is removed and the room taken back to the walls. This is where the original quote's exclusions surface: perished pipework, old wiring, or an uneven floor.
2. Structural changes (2–5 days, if any). Removing a wall for an open-plan layout means a steel beam and structural calculations signed off under the Building Regulations, and a party wall agreement where the wall is shared. This stage often waits on approval before it can start.
3. First-fix plumbing and electrics (2–3 days). Supplies, waste runs, and cabling are set into the walls for the sink, appliances, sockets, and lighting, to BS 7671, with the electrical work notifiable under Part P of the Building Regulations.
4. Plastering (2–3 days, plus drying). Walls are skimmed and made good. Fresh plaster has to dry before it can be painted, which is one of the quiet elapsed-time gaps.
5. Flooring (1–2 days). The floor is laid where it runs wall-to-wall, so the units sit on a finished floor.
6. Unit installation (2–4 days). Base and wall units are fitted, levelled, and secured. Nothing about the worktop can begin until this is complete.
7. Worktop templating and fabrication (1 day on site, then 1–2 weeks off-site). The fabricator templates the installed units, then a stone or quartz worktop is cut and finished over one to two weeks before it is fitted. This is the gap covered in the next section.
8. Worktop fit, splashback, and tiling (2–3 days). The worktop is installed, then the splashback and any tiling go in against it — never before it.
9. Second-fix plumbing and electrics (1–2 days). The sink, taps, hob, oven, and appliances are connected, and the sockets and lighting finished, by registered trades.
10. Snagging and sign-off (1 day). Every element is checked — door alignment, drawer runners, sealant, appliance function — and the building-control sign-off obtained where the work was notifiable, before final payment.

Add those up and the on-site trades total roughly ten to fifteen working days. If working days were all that mattered, the kitchen would be finished in a fortnight. They are not, which is the whole point.

The elapsed timeline: the weeks that happen off-site

The elapsed timeline adds the things the working timeline ignores, and they are usually larger than the fit itself. The first is procurement. Units, appliances, and a stone or quartz worktop all carry lead times measured in weeks — a kitchen ordered late does not start late by a few days, it starts late by the lead time of the slowest item. Bespoke and in-frame units run longest, and a single back-ordered appliance can hold the second fix.

The second is approvals. Removing a wall needs structural calculations and Building Regulations sign-off before the work can begin, and a party wall agreement adds notice periods of its own — weeks that happen before a single trade arrives, and which the Planning Portal sets out for England and Wales. The third is the worktop gap and plaster drying, covered next. Stack procurement, approvals, and drying on top of the working days and the same kitchen that takes fifteen labour days takes six to twelve weeks of elapsed time. The elapsed timeline is the one that matters, because it is the one you actually live through. The cost of each of those stages is set out in what a kitchen renovation costs.

The worktop gap: why the middle of every kitchen pauses

There is a point in every stone or quartz kitchen where the work appears to stop, and homeowners who did not plan for it assume something has gone wrong. Nothing has. The worktop cannot be templated until the units are installed and level, and once it is templated, the stone or quartz takes one to two weeks to fabricate before it can be fitted. For that fortnight the kitchen sits — units in, no worktop, no splashback, no sink — and there is genuinely nothing the other trades can do until the worktop is in.

This is the single most misunderstood part of the kitchen timeline, and it cannot be compressed by ordering the worktop early, because the fabricator templates the actual installed units, not the plan. The only way to manage the gap is to expect it: build it into the programme, do not book the second fix or the tiler for that fortnight, and understand that a stone or quartz kitchen has a structural pause in the middle that a laminate kitchen does not. A homeowner who plans for the gap runs a calm two weeks; one who did not spends it convinced the project has stalled. The same dependency is why the kitchen renovation checklist puts confirming the worktop lead time near the top of the list.

What makes a kitchen timeline slip

Kitchen timelines rarely slip because the fitters are slow. They slip because the off-site weeks were never planned for. The units are ordered after the start date is set, so the strip-out finishes and then the room waits. The worktop is templated late because the units ran behind, pushing the fabrication gap into the next month. The plaster is rushed and painted before it dried, and has to be redone. The structural sign-off is left late, so the wall cannot come down when the trades are free.

Each of these is invisible on the quote, because the quote prices the work, not the calendar around it. This is the gap the prepared homeowner closes: ordering units, appliances, and the worktop early enough that procurement finishes before the fit needs it, sequencing structural approval before the start date, and building the worktop gap and plaster drying into the programme rather than discovering them. The same planning that keeps the budget honest keeps the timeline honest — and the failures that break both are catalogued in the most expensive kitchen renovation mistakes.

Building a timeline you can actually hold

A realistic kitchen timeline is built backwards from the elapsed date, not forwards from the fit days. Start from when you need the kitchen finished, subtract the worktop gap, subtract plaster drying, subtract the procurement lead time of the slowest item, and subtract any structural approval window — and what is left is when the order actually has to be placed to hit the date. Most homeowners run it the other way, start from today, add up the fit days, and arrive at a finish date that was never possible.

The 12-Phase System is built to put that planning in the homeowner's hands before the project starts — the working sequence, the elapsed gaps, the procurement and approvals that have to be cleared first, and the buffers that absorb a late delivery. Phase awareness is what turns a homeowner from someone surprised by every off-site week into someone who planned for it. It is also where the four nations differ: the building-control and structural-approval regime varies across England, Wales, Scotland, and Northern Ireland, even though the fit sequence does not.

Frequently asked questions

How long does a kitchen renovation take in the UK?

A standard kitchen carries roughly ten to fifteen working days of on-site trades, but takes six to twelve weeks of elapsed time once procurement lead times, the worktop fabrication gap, plaster drying, and any structural approval are counted. The working time is the short, visible part; the elapsed time is the number that matters, because it is the one you actually live through. A bespoke kitchen or one with a knock-through runs towards the longer end.

Why is there a two-week gap in the middle of my kitchen fit?

Because the worktop cannot be templated until the units are installed and level, and once templated, a stone or quartz worktop takes one to two weeks to fabricate before it is fitted. During that period the units are in but the worktop, splashback, sink, and second fix cannot proceed. It is a structural pause built into every stone or quartz kitchen, and it cannot be removed by ordering the worktop earlier, because the fabricator measures the installed units, not the plan.

When should I order the kitchen units and appliances?

As early as possible, ideally the day the design and contract are confirmed, because the lead time of the slowest item sets the start date. Units, especially bespoke or in-frame ranges, and some appliances carry lead times measured in weeks. Ordering after the start date is fixed means the strip-out finishes and the room then waits for the delivery, turning a procurement delay into an on-site one.

Do I need approval to remove a wall for an open-plan kitchen?

Removing a load-bearing wall requires structural calculations and Building Regulations sign-off, usually with a steel beam, and a party wall agreement where the wall is shared with a neighbour. These approvals take time before any work can start, so they belong at the front of the timeline. Requirements and the building-control route differ across England, Wales, Scotland, and Northern Ireland, so confirm the regime that applies where you live.

Does plaster really need to dry before painting?

Yes. Fresh plaster needs to dry out before it can be sealed and painted, and the time depends on the conditions and the thickness. Painting plaster before it has dried traps moisture and causes the paint to flake, which means redoing it. The drying period is one of the quiet elapsed-time gaps that does not show up as a working day but still holds up the finish.

What is the difference between working time and elapsed time on a kitchen?

Working time is the number of days a trade is physically on site. Elapsed time is the number of days from deciding to renovate to the finished, signed-off kitchen. The two are far apart in a kitchen because procurement, the worktop fabrication gap, plaster drying, and structural approval all consume elapsed time without consuming working time. Planning to working time is the single most common reason a kitchen finishes far later than expected.
