Full house refurbishment cost in 2026 — UK price guide
A full house refurbishment is the largest single project most homeowners commission — typically 14–24 weeks on site with £60k–£250k spent. The cost varies dramatically with scope, building age and finish level. This 2026 guide breaks down per-m² rates for cosmetic, mid-spec and full strip-and-rebuild refurbishments across the UK, what drives the variation, the timeline, and the most common ways homeowners overspend. All figures are RCB Design & Build delivery costs from the last 18 months.

What drives the cost
M&E condition
A full rewire on a 4-bedroom house: £8k–£15k. A full replumb including new central heating boiler and radiators: £8k–£14k. Pre-1970s housing almost always needs both. A 2010s house with sound services can skip both.
Plaster strategy
Hack-off and re-plaster on a 3-bed terrace: £8k–£15k. Overboard with new plasterboard: £6k–£11k. Skim only: £3k–£6k. Choice depends on existing condition.
Mid-range kitchen: £8k–£15k. Premium kitchen: £20k–£60k. Family bathroom mid-range: £4k–£8k. Premium bathroom: £8k–£20k. These are client supply costs — installation labour is separate.
Heating system
New gas boiler + replumb: £5k–£8k. Air-source heat pump + new emitters: £12k–£18k. Wet underfloor heating throughout ground floor: £4k–£8k.
Insulation upgrades
External wall insulation: £15k–£28k on a 3-bed semi. Loft top-up insulation: £600–£1,200. Sash window draught-stripping: £2k–£4k per floor.
Asbestos and lead
Pre-2000 housing should always be surveyed. Asbestos removal: £1k–£4k per identified item. Lead pipe replacement: £2k–£6k.
The single most useful number is £/m² of internal floor. For a typical mid-terrace at 110 m², a full strip-and-rebuild at £2,000/m² comes to £220,000 before client-supply kitchen, bathroom and flooring. Add £25k–£60k of client supply for those, and you're at £245k–£280k total project cost. The most common budget mistake is failing to allow for client supply — homeowners see a £200k builder quote and forget they still need £40k of kitchen, bathroom and flooring on top.
Cosmetic vs full refurb — which one do you need?
If the property has been refurbished in the last 10 years and you like the layout, a cosmetic refresh at £400–£800/m² gets you fresh paint, new carpets and minor repairs. If the property is structurally sound but tired, mid-spec at £1,000–£1,800/m² delivers new kitchen, bathroom and decoration without ripping out M&E. If the property is pre-1970s and hasn't been touched, full strip-and-rebuild at £1,800–£2,800/m² is almost always the right call — you'll uncover failed services and rotted joists either way, and it's cheaper to do it all in one programme than discover it mid-project.
How long does a refurbishment take?
For a typical 100–140 m² mid-terrace, plan on 14–22 weeks on site after 6–8 weeks of design and procurement. Listed buildings and conservation areas can add 6–12 weeks of consenting on top. The single biggest schedule risk is M&E — once walls and ceilings are open, surveys often reveal more rewire or replumb than originally scoped. We always agree contingency upfront (typically 10% of the M&E budget).
How to control refurbishment cost
Three biggest control levers: (1) decide finish level early and stick to it — switching from mid-spec to premium mid-project adds 20–40%; (2) keep load-bearing walls in place where possible — every steel beam adds £4k–£8k; (3) supply your own kitchen, bathroom and flooring to save 10–15% trade markup. Avoid value-engineering insulation or M&E — both are nearly impossible to upgrade later without ripping out new finishes.
Refurbishment vs new build
In London, refurbishment is almost always cheaper than knock-down-and-rebuild — £2,000/m² vs £3,500–£4,500/m² for new build, plus you avoid VAT (refurbishment is zero-rated only on listed buildings, otherwise 20% — but the existing building shell saves more than the VAT). New build is right when the existing layout fundamentally doesn't work or the structural condition is unrecoverable.
Frequently asked questions
How much does a full house refurbishment cost in 2026?
A full strip-and-rebuild refurb in London costs £1,800–£2,800/m² in 2026 — so £198,000–£308,000 for a typical 110 m² mid-terrace, before client-supply kitchen, bathroom and flooring.
What's included in a refurbishment price?
Our quotation includes strip-out, structural alterations, full rewire and replumb (where in scope), plaster, insulation, joinery, and kitchen/bathroom installation (client supplies units). Sanitaryware, tiles, final flooring and paint are client-supplied.
How long does a refurbishment take?
Plan on 14–22 weeks on site for a typical 100–140 m² mid-terrace, plus 6–8 weeks of design and procurement before mobilisation. Listed buildings and conservation areas can add 6–12 weeks.
Can I live in the house during a refurb?
For a cosmetic refresh, yes. For a mid-spec refurb (kitchen and bathroom rip-out), most people move out for 4–6 weeks of the worst phase. For a full strip-and-rebuild, you have to vacate — the house has no kitchen, bathrooms or in some cases plumbing for 8–12 weeks.
What's the cheapest type of refurbishment?
A cosmetic refresh — paint, new flooring, minor repairs — costs £400–£800/m². It works when the layout, M&E and bathrooms are recent and don't need touching.
Do I need planning permission for a refurb?
Internal alterations rarely need planning permission. Structural changes (load-bearing wall removal, chimney removal) need Building Control approval. Listed buildings need LBC for almost any internal change. Conservation areas need consent for external changes (windows, render, roof).
How do I avoid overspending on a refurb?
Decide finish level early. Get a fixed-price contract with a clear scope. Allow 10% contingency for M&E surprises. Supply your own kitchen, bathroom and flooring. Keep load-bearing walls where possible.
