Refurb cost per room in the UK: the honest answer

Averaging refurbishment costs per room mixes jobs that have nothing in common. Within a single tired terrace, the bedroom that needs paint and carpet, the bathroom that needs a full refit and the kitchen that needs moving to the back room are one "room" each, at wildly different costs. Between properties it gets worse: the average blends light refreshes with back-to-brick renovations, landlord specs with family-home specs, and cheap-labour areas with expensive ones. Whatever number emerges describes none of the jobs in it.

The variation is not noise around a useful average; it is the signal itself. Two three-bed houses on the same street can honestly carry refurbishment budgets that differ by a multiple of each other, because one needs decorating and the other needs a roof, a rewire and a damp course. A budget built by multiplying a rooms count by a borrowed per-room figure has skipped the only step that matters, which is finding out which of those houses you are buying.

Price each room by deciding its scope first, then costing the elements that scope actually contains. For every room, ask which of these apply: strip-out and disposal; structural or damp remediation; first-fix electrics and plumbing; plastering or boarding; second-fix electrics and plumbing; and finishes, meaning kitchen units and worktops, sanitaryware, tiling, flooring and decoration. A cosmetic room touches only the last item. A full refit touches most of them. Writing the scope down per room is what turns a guess into a schedule, and it is also what a builder can actually quote against.

Keep whole-house items out of the rooms and price them once: roof, windows and external doors, boiler and heating system, rewire, damp course, external decoration. Spreading a rewire across rooms hides it; itemising it makes the schedule honest. Then apply local rates: quotes from tradespeople who have seen the property or the photographs, day rates typical of the area, and merchant prices for the materials at your chosen spec. Two rules keep the schedule truthful at the edges: a genuinely clean, recently finished room can be priced at nothing, and pricing it anyway pads the budget until good deals die for no reason; but dated-and-clean is not the same as done, because if your end buyer or tenant expects better, the tired bathroom that technically works still belongs in the schedule.

The same schedule of works costs different amounts in different places, chiefly because labour rates differ across the country, and labour is the larger share of most refurbishment budgets. Access and logistics move costs too: parking, storage, floors above ground level and restricted working hours all add labour time. This is why borrowed figures from a forum or a course, priced in someone else's town, transplant so badly, and why local quotes beat national tables.

Include VAT in every figure you compare, because a schedule quoted ex-VAT against one quoted inclusive is an error waiting to be discovered at the worst time. Most refurbishment work on occupied or recently occupied homes is standard-rated, though reduced rates exist for some cases such as properties empty for a long period; the rules are on GOV.UK and worth checking when a property has stood empty. And always carry a contingency, around 15 percent, on top of the summed schedule: opened-up walls and lifted floors reliably reveal work no survey priced, and a budget without contingency is not a budget, it is a best case.

While no honest national per-room figure exists, measured whole-property figures do. Across 2,545 properties analysed by PropDetect, the median modelled whole-property refurbishment cost is 11,795 pounds including VAT, as of 5 September 2026. That median describes the middle of a wide distribution dominated by lighter schemes, not what any particular property will cost, but it anchors the scale: most refurbishments priced from real listings are closer to a solid cosmetic-plus scheme than to a back-to-brick renovation.

Size moves the figure the way you would expect, because more rooms means more scope: the medians run from 8,160 pounds for one-bedroom properties to 35,509 pounds for properties with five or more bedrooms, as of the same date. Place moves it too: area medians range from 6,734 pounds in Dundee to 20,492 pounds in Coventry, a spread that reflects both the local housing stock's condition and local pricing. The full breakdown by size and area is published and kept current at /data/refurb-costs-by-region.

No per-room medians are published yet, and that is deliberate: as this guide has argued, a per-room average detached from scope and spec would misinform more than it informs. What exists instead is a per-property answer: every PropDetect analysis includes a room-by-room refurbishment breakdown priced from that property's own photographs and condition, which is the honest version of the per-room number this page's question is really asking for.

On an actual appraisal the sequence is short. Walk the photographs, or better the property, room by room, and write a scope for each: nothing, cosmetic, partial, or full refit. Price each room's elements at local rates, add the whole-house items once, sum, add around 15 percent contingency, and include VAT. Then sanity-check the total in both directions: against the measured medians above for scale, and against the finished standard your end value assumes, because a GDV built on renovated comparables commits you to delivering that standard, and a refurb budget that will not reach it makes the end value fiction.

Treat the schedule as a living document. A viewing sharpens it, a builder's walk-through sharpens it again, and the first week on site will test it. The method's value is not that the first number is right; it is that every revision lands in an itemised schedule where you can see what changed and why, instead of vanishing into a per-room guess that was never accountable to anything.
