Full House Renovation Cost UK 2026: What a Complete Gut-and-Refurb Actually Costs
Quick Answer
A full house renovation (complete gut and refurb) costs £80,000–180,000+ for a standard 3-bedroom UK property depending on specification. Cost per m² ranges from £900–1,800/m² at standard specification. Doing a full renovation in one phase is 20–35% cheaper than doing it piecemeal, because trades can sequence efficiently and disruption is consolidated.
The phrase "full house renovation" gets used loosely. Sometimes it means a new kitchen, a bathroom refresh and a lick of paint — cosmetic work done over a few weeks. What I'm talking about here is the real thing: a complete gut-and-refurb, where the property is stripped back to its bones, every system is replaced, and it comes out the other side genuinely new inside.
I've been doing this for 32 years. A full renovation of a 3-bedroom Victorian terrace — the most common scenario I see — costs £80,000–£180,000+ in 2026. The range is wide because the variables are enormous: the condition of what you find once the walls are open, the specification you're building to, and your location in the country. This guide breaks down every trade, explains why phasing matters, and covers the costs that most renovation budgets ignore until it's too late.
The base example throughout this guide is a 3-bedroom Victorian terrace of approximately 90 m², purchased in need of full renovation — typical of what an investor, developer, or owner-occupier might take on.
Total Cost: What to Budget by Spec Level
Before diving into the trade breakdown, here's the headline number by specification level for a 3-bedroom Victorian terrace at approximately 90 m² gross internal area. These figures include all works from strip-out to final decoration and flooring — fully habitable at completion.
| Specification Level | Cost Range | What's Included |
|---|---|---|
| Budget / investor spec | £80,000–£110,000 | Functional standard: mid-market kitchen and bathroom, rewire, new boiler and heating, replaster, redecorate. Not luxury but solid and lettable. |
| Standard / owner-occupier spec | £110,000–£150,000 | Quality kitchen, two good bathrooms, new windows if needed, rewire, underfloor heating to ground floor, solid floor covering, full replaster and professional decoration. |
| High spec / premium finish | £150,000–£180,000+ | Bespoke kitchen, high-end bathrooms, engineered timber floors, underfloor heating throughout, premium sanitary ware, feature lighting, high-specification decoration. Suitable for sale or personal use at the top of the market. |
These figures exclude VAT (which applies at 20% on most new construction work but at 5% on some renovation work under the reduced-rate scheme — take advice from your accountant on what qualifies). They also exclude any structural extension, loft conversion, or other addition — those are priced separately.
Full Renovation Cost per m²
Cost per m² is the most useful metric for comparing renovation scope across properties of different sizes, and for sense-checking contractor quotes. The figures below reflect gross internal area (the full floor area of all floors combined).
| Spec Level | Cost per m² (GIA) | Example: 90 m² house |
|---|---|---|
| Budget / investor | £900–£1,100/m² | £81,000–£99,000 |
| Standard / owner-occupier | £1,100–£1,400/m² | £99,000–£126,000 |
| High specification | £1,400–£1,800/m² | £126,000–£162,000 |
These are whole-house averages. In practice, wet rooms and kitchens cost far more per m² than a bedroom — a kitchen might cost £800–£2,500/m² of kitchen floor area depending on specification, while a bedroom might cost £350–£600/m². The average reflects the mix of rooms across the whole property.

|---|---|---|---|---|
| Strip-out and demolition | £3,000–£5,000 | £4,000–£7,000 | £5,000–£8,000 | Includes skip hire; period properties with lath and plaster cost more to strip |
| Structural and damp works | £3,000–£8,000 | £5,000–£12,000 | £6,000–£15,000 | Damp-proof course, wall ties, beam alterations, padstones; highly variable by condition |

| Kitchen — supply and fit | £8,000–£14,000 | £14,000–£25,000 | £25,000–£55,000+ | Includes units, worktops, appliances, fitting and first-fix to kitchen trades |
| Bathrooms — supply and fit (×2) | £5,000–£9,000 | £9,000–£18,000 | £18,000–£40,000 | Family bathroom plus en suite; tiling, sanitary ware, heated towel rail, fit-out |
| Full rewire | £4,500–£7,000 | £5,500–£8,500 | £7,000–£12,000 | Consumer unit, all circuits, sockets, switches, lighting points; Part P certification |
| Plumbing and heating system | £8,000–£14,000 | £12,000–£22,000 | £18,000–£35,000 | New combi boiler or heat pump, radiators or UFH, cylinder if applicable, all pipework |
| Plastering — full replaster | £7,000–£11,000 | £9,000–£14,000 | £10,000–£16,000 | Dot-and-dab or sand and cement with skim on all walls and ceilings throughout |
| Decorating — full internal | £4,000–£7,000 | £6,000–£10,000 | £8,000–£16,000 | Prep, prime, two coats throughout; higher spec includes feature treatments |
| Flooring — throughout | £5,000–£9,000 | £8,000–£14,000 | £14,000–£30,000 | LVT and carpet at budget; engineered timber, stone tile and high-spec carpet at upper end |
| Carpentry — joinery and stairs | £3,000–£5,000 | £5,000–£9,000 | £8,000–£18,000 | Skirting, architrave, internal doors, staircase refurbishment or replacement |
| Total construction (excl. design, fees, contingency) | £68,000–£102,000 | £97,000–£152,000 | £137,000–£285,000+ | Add 15% for design, fees, contingency and skip hire |
These ranges are deliberately broad because conditions inside period properties vary enormously. On a Victorian terrace, it is common to discover rising damp that was hidden behind chipboard, original knob-and-tube electrics inside the wall cavities, or cast iron waste pipes that need full replacement. A 10–15% contingency is not pessimism — it is professional project management.
Why Doing It All at Once Is Cheaper
I see this every year: homeowners who buy a property, renovate it in stages because they're living in it or because funds are limited, and end up spending 25–35% more than they would have done with a single coordinated programme. Here's why the numbers work out that way.
Trades Mobilise Once, Not Three Times
Every time a trade returns to a property, there's a minimum charge for mobilisation, travel, tool setup, and the time to re-familiarise with the job. An electrician who does the whole house in one visit charges less than one who comes back three times for three separate rooms. The same applies to plasterers, plumbers, and decorators. A whole-house programme lets every trade work through the property in the correct sequence without returning.
Plaster Goes on Once
Replastering a whole house at once means consistent finish, consistent drying conditions, and one mobilisation for the plastering gang. If you replaster the kitchen now, then the hallway in two years, then the upstairs rooms later, each round requires patching edges to meet existing work, colour-matching, and a separate pricing uplift for mobilisation. The aggregate cost is significantly higher.
The Correct Trade Sequence
A whole-house renovation runs in a defined sequence: strip-out, structural and damp, first fix electrics and plumbing, insulation and boarding, plastering, second fix electrics and plumbing, joinery, tiling, decorating, flooring. This sequence only makes sense as a whole. If you try to do it room by room, you are constantly managing the transition between finished and unfinished areas, protecting finished surfaces from trade damage, and paying for returns.
Site Setup Shared Across the Whole Job
Skip hire, site protection, scaffold hire (where needed), temporary services, welfare facilities, storage — all of these fixed costs are shared across the whole project when it's done at once. Done piecemeal, you pay for each element multiple times.

Standard renovation runs £110,000–£150,000. High specification runs £150,000–£180,000+. These figures include strip-out, structural and damp work, roof, windows, kitchen, bathrooms, rewire, heating, plastering, decorating and flooring. Fees, contingency and temporary accommodation are additional.
What does full house renovation cost per m² in the UK?
Full house renovation cost per m² in the UK runs £900–£1,800 in 2026 depending on specification. Budget spec sits at £900–£1,100/m². Standard spec sits at £1,100–£1,400/m². High spec sits at £1,400–£1,800/m². A 3-bed Victorian terrace at roughly 90 m² at standard spec costs approximately £99,000–£126,000 in construction costs before fees and contingency.
Is it cheaper to renovate all at once or room by room?
Renovating the whole house at once is significantly cheaper than doing it room by room. Trades are sequenced efficiently in one programme, plaster goes on across the whole house at once, skips and site setup are shared costs, and there is no wasted mobilisation. Piecemeal renovation typically costs 20–35% more in total.
What are the hidden costs of a full house renovation?
The most common hidden costs are: Building Control fees (£700–£1,500), structural engineer (£500–£1,500), asbestos survey and removal on pre-2000 properties (£300–£5,000+), skip hire (£600–£2,500), temporary accommodation (£6,000–£25,000+ depending on duration), party wall agreements if needed (£800–£2,500 per neighbour), and contingency (budget 10–15% of construction cost).
Do I need Building Regulations for a full house renovation?
Many elements of a full house renovation require Building Regulations approval: structural alterations (wall removals, beam changes), a full rewire (notified under Part P), a new boiler and heating system (Gas Safe engineer and notification), and any new or replacement windows (thermal performance compliance). If you are adding an extension or loft conversion, full Building Regulations approval is required for those elements separately.
How long does a full house renovation take?
A full gut-and-refurb of a 3-bedroom house typically takes 16–28 weeks from site start to completion. Strip-out and structural work: 4–6 weeks. First fix trades: 3–5 weeks. Plastering: 2–3 weeks plus drying. Second fix and finishing: 4–6 weeks. Build in 10–15% programme contingency for delays from material lead times, Building Control inspection slots, and trade availability.
How much does a full house renovation cost for a 4-bedroom house?
A full house renovation for a 4-bedroom UK property (typically 110–130 m² gross internal area) costs £100,000–£220,000+ in 2026 depending on specification. At standard specification the cost per m² runs £1,100–£1,400/m², giving a range of approximately £121,000–£182,000 for a 110 m² property. The kitchen and bathrooms drive much of the cost variance — a 4-bed property is likely to have 2–3 bathrooms, and each bathroom adds £8,000–£18,000 at standard spec. See our house renovation cost per m² guide for further benchmarks.
Is VAT charged on renovation work in the UK?
Most renovation work on a residential property is subject to 20% VAT. However, a reduced 5% rate applies when renovating an empty property unoccupied for 2 or more years, converting non-residential buildings to residential use, or installing qualifying energy-efficiency measures such as insulation and heat pumps. New build is zero-rated. Confirm with your contractor which rate applies — the difference between 5% and 20% on a £120,000 programme is £18,000. See GOV.UK for the latest guidance.
