A full house refurbishment is one of the largest investments a London homeowner can make and one of the hardest to budget accurately. Quotes for the same property can vary by £80,000 or more depending on the scope of work, the specification level, and which London borough you’re in.
This guide breaks down the full cost of a whole house refurbishment in London for 2026 by property size, by trade, phase by phase, and borough by borough so you know exactly what to expect before you speak to a single builder. All figures include VAT at 20% unless stated otherwise.
What does a full house refurbishment cost in London in 2026?
The average full house refurbishment cost in London ranges from £800 to £2,500 per m² depending on the level of work. For a typical London property, that translates to a total project cost of:
| Scope level | What’s included | Cost per m² | Typical total (3-bed house) |
|---|---|---|---|
| Light refurbishment | Decoration, flooring, new kitchen & bathroom | £800–£1,200/m² | £45,000–£90,000 |
| Full refurbishment | Full rewire, replumb, replaster, new kitchen & bathrooms | £1,200–£1,800/m² | £100,000–£160,000 |
| Structural refurbishment | All of above + structural changes, extensions, layout alterations | £1,800–£2,500/m² | £160,000–£240,000 |
| High-end / full specification | Bespoke finishes, smart home, basement, heritage features | £2,500–£3,500+/m² | £250,000–£350,000+ |
Why such a wide range?
The cost of a full house refurbishment in London is driven by five main variables: the current condition of the property (a Victorian terrace with original wiring costs far more to refurbish than a 1980s semi), the scope of structural changes, the specification of fixtures and fittings, the borough, and the contractor. We cover each of these in detail below.
Full house refurbishment cost by property size in London
Property size is the single most reliable predictor of refurbishment cost. The table below shows typical total costs for a full refurbishment (not cosmetic-only) by property type in London, meaning a full rewire, replumb, replaster, new kitchen, new bathroom(s), and decoration throughout.
| Property type | Approx. floor area | Full refurb cost | High-spec cost |
|---|---|---|---|
| Studio / 1-bed flat | 35–55 m² | £45,000–£75,000 | £75,000–£120,000 |
| 2-bed flat | 55–80 m² | £70,000–£110,000 | £120,000–£170,000 |
| 2-bed terraced house | 70–95 m² | £80,000–£130,000 | £130,000–£200,000 |
| 3-bed semi-detached | 90–120 m² | £105,000–£160,000 | £165,000–£250,000 |
| 3-bed Victorian terraced | 95–130 m² | £120,000–£185,000 | £185,000–£280,000 |
| 4-bed detached / townhouse | 140–200 m² | £185,000–£280,000 | £280,000–£420,000 |
| 5-bed+ family home | 200–300+ m² | £260,000–£400,000+ | £400,000–£650,000+ |
These figures assume the property is liveable but dated not derelict. A property requiring remedial structural work, asbestos removal, or significant damp treatment will sit at the upper end or above these ranges.
Whole house renovation cost by scope: what’s actually included?
The word “refurbishment” covers a huge spectrum of work. These are the four common scope tiers and what builders actually price within each one:
| Tier | Work included | What’s not included |
|---|---|---|
| Cosmetic / light | Decoration, flooring, new kitchen units and appliances, one bathroom suite, new doors and hardware | Rewire, replumb, replaster, structural changes |
| Full (non-structural) | All of above + full rewire, consumer unit replacement, full replumb (boiler, radiators, pipework), replastering throughout, insulation upgrades | Structural changes, extensions, layout changes |
| Structural | All of above + wall removal (RSJ steels), floor levelling, staircase replacement, layout reconfiguration | Extensions, basement, loft conversion |
| Full specification | All of above + bespoke joinery, underfloor heating, smart home systems, high-end sanitaryware, landscaping | Nothing this is the complete package |
Common scope creep to plan for
Many homeowners start with a cosmetic brief and discover during strip-out that electrical or plumbing systems need full replacement. Budgeting for a full refurbishment from the outset and being pleasantly surprised if the systems are in better condition is a safer approach than planning light and being forced into a full rewire mid-project.
Full house refurbishment cost per m² in London (2026)
Cost per m² is the most useful way to benchmark quotes against each other and against your budget but it must be applied to the gross internal floor area, not just the ground floor.
| Specification level | Cost per m² (inc. VAT) | Typical use case |
|---|---|---|
| Budget / investor grade | £800–£1,100/m² | Buy-to-let, quick turnaround, neutral palette |
| Standard / mid-spec | £1,100–£1,600/m² | Family home, good quality but not bespoke |
| High spec | £1,600–£2,200/m² | Owner-occupier, premium finishes, smart systems |
| Premium / luxury | £2,200–£3,500+/m² | Prime London postcodes, bespoke everything |
A 110 m² Victorian terrace refurbished to mid-spec would therefore cost approximately £121,000–£176,000 inc. VAT. If your quoted price per m² falls significantly below £800, probe what has been excluded. A quote that appears cheap at this level almost always means something significant has been omitted.
House refurbishment cost breakdown by trade
For a typical 3-bed Victorian terraced house (approx. 110 m²) undergoing a full refurbishment in London, the trade breakdown looks like this:
| Trade / element | Scope | Typical cost (3-bed London) |
|---|---|---|
| Kitchen | Mid-spec units, appliances, worktops, tiling, plumbing, electrics | £15,000–£35,000 |
| Bathroom (main) | Full suite, tiling, underfloor heating mat | £6,000–£14,000 |
| En suite / second bathroom | Smaller room, shower enclosure, tiling | £4,000–£9,000 |
| Full rewire | New consumer unit, all circuits, sockets, switches, lights | £8,000–£16,000 |
| Full replumb | New boiler, radiators, pipework throughout, hot/cold supply | £8,000–£18,000 |
| Plastering | Skim throughout (or full render where needed) | £6,000–£14,000 |
| Flooring | Engineered wood, LVT or carpet throughout | £5,000–£15,000 |
| Decoration | Two coats throughout, ceilings, woodwork | £5,000–£10,000 |
| Structural steel (RSJ) | Wall removal + steel beam, if required | £4,000–£10,000 per opening |
| Windows and doors | uPVC or timber sash replacement throughout | £6,000–£20,000 |
| Insulation | Loft, solid wall (internal), floor where accessible | £3,000–£10,000 |
| External works | Repointing, fascias, guttering, front path | £2,000–£8,000 |
Phase-by-phase cost breakdown for a full house refurbishment
Understanding the order of work helps you manage cash flow, ask better questions of your builder, and identify if progress has stalled. A full refurbishment follows this sequence:
PHASE 01
Strip-out and demolition
£2,000–£7,000
Removal of existing kitchen, bathrooms, flooring, ceilings, partition walls. Skip hire, asbestos testing if pre-2000 property.
PHASE 02
Structural and groundwork
£5,000–£30,000
Wall removals, steel beams, underpinning if required, floor levelling, damp-proofing treatment.
PHASE 03
First fix (services)
£15,000–£35,000
All pipework, wiring, ventilation, and soil stacks installed before walls are closed up. Electrician and plumber working simultaneously.
PHASE 04
Plastering and drying time
£6,000–£14,000
Skimming, coving, and any patching. Allow 4–6 weeks’ drying time before decorating; rushing this is the most common cause of cracking.
PHASE 05
Second fix (finishes)
£10,000–£22,000
Sockets, switches, radiators, sanitaryware, kitchen units and appliances, internal doors and ironmongery.
PHASE 06
Decoration and flooring
£10,000–£25,000
Painting, tiling, laying all floor finishes. Final snagging and builder clean. Usually last 4–6 weeks of the programme.
Victorian and period property refurbishment costs in London
The majority of London’s housing stock was built before 1939, and period properties carry specific cost challenges that standard cost guides routinely underestimate. If you own a Victorian or Edwardian terrace, which accounts for millions of London homes, budget for the following additional work:
| Period property challenge | What it means | Typical additional cost |
|---|---|---|
| Solid brick walls | No cavity thermal insulation must go on the inside, losing floor area and requiring full replaster | £5,000–£15,000 (internal wall insulation) |
| Suspended timber floors | Older boards may require replacing; insulation underneath needs board removal and reinstatement | £3,000–£9,000 |
| Original sash windows | Draughty; whether to restore or replace is a conservation area question. Restoration costs more than uPVC but may be required | £800–£1,600 per window to restore |
| Asbestos (pre-1980 properties) | Artex ceilings, floor tiles, pipe lagging, roof felt may all contain asbestos survey and licensed removal required | £500–£4,000 (survey + removal) |
| Rising or penetrating damp | Original slate damp-proof courses fail; walls may need chemical injection DPC, tanking or French drains | £2,000–£10,000 depending on severity |
| Outdated wiring (rubber/aluminium) | Pre-1970s wiring is unsafe and must be fully replaced will fail Part P certification | Included in full rewire (£8,000–£16,000) |
| Lead pipework | Common in pre-1970 properties; must be replaced to meet modern water quality standards | Included in full replumb (£8,000–£18,000) |
Survey before you budget
Always commission a full structural survey (RICS Level 3 Building Survey, from £600–£1,200) before finalising your refurbishment budget. The survey will flag hidden defects, subsidence, roof structure issues, and chimney condition that can add tens of thousands to your costs if discovered during works rather than before.

Full house refurbishment cost by London borough
Labour costs vary significantly across London. Inner central boroughs command a 20–35% premium over outer London boroughs, partly due to logistics (parking, restricted hours, congestion charge) and partly due to the calibre of contractor typically working in those areas.
| Zone | Boroughs | Labour premium vs. outer London |
|---|---|---|
| Central | City of London, Westminster, Kensington & Chelsea, Camden, Islington, Hammersmith & Fulham, Southwark, Lambeth, Hackney, Tower Hamlets, Wandsworth, Lewisham | +20–35% |
| North London | Barnet, Haringey, Enfield, Waltham Forest | +10–20% |
| East London | Newham, Redbridge, Barking & Dagenham, Havering, Bexley | +5–15% |
| South London | Croydon, Bromley, Merton, Sutton, Kingston, Richmond | +8–18% |
| West London | Ealing, Hillingdon, Hounslow, Harrow, Brent | +5–12% |
For a 110 m² Victorian terrace, the same full refurbishment scope would cost approximately £120,000–£145,000 in outer east London versus £155,000–£190,000 in Kensington or Chelsea. Borough location also affects access costs (scaffolding times, skip permits, parking suspensions), which can add £2,000–£6,000 to a central London project.
Professional fees for a full house refurbishment
Professional fees for a whole house refurbishment in London typically add 10–18% on top of build costs. On a £150,000 project, that means £15,000–£27,000 in fees before works begin. Here is what you are paying for:
| Professional | When needed | Typical fee |
|---|---|---|
| Architect / designer | Any structural change, layout alteration, or planning application | 8–15% of build cost, or £5,000–£25,000 fixed |
| Structural engineer | Any wall removal, beam specification, foundation work | £1,200–£3,500 per project |
| Project manager / main contractor overhead | If hiring separate trades rather than a main contractor | 10–15% of build cost |
| RICS building survey | Before purchase or before refurbishment begins | £600–£1,200 |
| Planning permission application | Any material change of use or external alteration in restricted area | £206 (application fee) + design costs |
| Building control / inspector | Structural work, rewire, new drainage, loft conversion | £750–£2,500 (local authority or approved inspector) |
| Party wall surveyor | Any work within 3–6m of a party wall (common in terraces) | £700–£2,000 per neighbour |
| Interior designer | Specification of finishes, furniture, soft furnishings | £1,500–£8,000+ (or day rate £500–£1,500) |
Hidden costs of a full house refurbishment in London
Most refurbishment quotes cover the core build works. The following costs are frequently omitted from initial quotes and catch homeowners by surprise — budget for all of them from the start.
| Hidden cost | Typical amount | Notes |
|---|---|---|
| Temporary accommodation | £1,500–£6,000/month | A full refurb usually requires you to vacate for 16–26+ weeks |
| Storage for furniture and belongings | £200–£600/month | Self-storage or pods; often overlooked in budget planning |
| Skip hire and waste removal | £2,000–£6,000 | Multiple skips over project duration; central London skip permits add cost |
| Scaffolding | £1,500–£5,000 | Required for roof work, chimney, upper window replacement, rendering |
| Contingency fund | 15–20% of build cost | Industry standard for full refurbishment; not optional on period properties |
| Appliances and sanitaryware | £3,000–£20,000+ | Often excluded from kitchen and bathroom quotes confirm what’s supplied |
| Curtains, blinds, and soft furnishings | £3,000–£12,000 | Consistently forgotten until move-in; bespoke blinds for period windows cost more |
| Lighting (supply only) | £2,000–£10,000 | Electrician labour is included in rewire; pendants, spotlights, and fittings usually are not |
| Asbestos survey and removal | £500–£4,000 | Legally required before demolition of any pre-2000 building fabric |
| Parking suspension and permits | £500–£2,500 | Central and inner London boroughs charge for builders’ parking bays |
| Congestion and ULEZ charges | £800–£3,000 | Builders’ vehicles visiting daily in the ULEZ zone often passed on to client |
| Snagging and remedial works | £500–£5,000 | Post-completion fixes; a professional snagging survey (£300–£600) is worth commissioning |
The real total cost
Add 15–20% contingency, 10–18% professional fees, and the hidden costs above to any builder quote. On a £150,000 build cost, the true all-in cost to a London homeowner is typically £190,000–£225,000 once fees, contingency, accommodation, and finishes are included.
VAT on a full house refurbishment in London
VAT applies at 20% on most house refurbishment works in the UK. All figures in this guide include VAT at the standard rate. However, there are two important exceptions:
5% reduced rate: If the property has been empty for two years or more, VAT on the refurbishment work is charged at the reduced rate of 5%. This can save £15,000–£30,000 on a major project. The contractor must verify the vacancy period through council tax records.
Zero rate: If you are converting a building from commercial to residential use, or converting a property to create additional dwellings, zero-rate VAT may apply to eligible works. HMRC Notice 708 covers both reduced-rate and zero-rate conditions in full.
What you cannot recover: Unlike developers who are VAT-registered and reclaim input tax, homeowners refurbishing their own residence cannot recover VAT. Budget on the gross figure inclusive of VAT.
Planning permission and building regulations for a house refurbishment
A straightforward internal refurbishment — rewire, replumb, new kitchen and bathrooms, redecoration does not require planning permission. However, you will need it and/or building regulations approval in several common scenarios:
| Work type | Planning permission? | Building regulations? |
|---|---|---|
| Internal decoration and flooring | No | No |
| New kitchen or bathroom (no structural change) | No | No (electrics need Part P sign-off) |
| Full rewire | No | Yes Part P electrical sign-off required |
| New boiler or heating system | No | Yes Gas Safe certificate required |
| Removal of non-structural internal wall | No | No (confirm wall is non-load-bearing) |
| Removal of load-bearing wall | No | Yes structural engineer calculations + building control sign-off |
| Change to external appearance (windows, cladding, rendering) | Sometimes especially in conservation areas or on listed buildings | Yes Part L energy efficiency requirements |
| Property in conservation area | Yes for many external changes check with your LPA | Varies |
| Listed building — any works | Listed building consent required for all works, internal and external | Yes |
London has over 50 conservation areas spread across its 33 local planning authorities. If your property sits within one, consult your local authority before specifying any external changes; failure to obtain consent can result in enforcement action and costly reinstatement.
Does a full house refurbishment add value in London?
Yes — but not always in proportion to cost. The return depends heavily on the current condition of the property, the local market, and the specification level. Overcapitalising (spending more on refurbishment than the finished property value justifies) is a genuine risk, particularly in outer London markets with lower ceilings on property values.
| Refurbishment type | Typical value uplift | Notes |
|---|---|---|
| Cosmetic refresh (decoration, flooring) | +5–10% | High ROI low cost, good saleability impact |
| New kitchen | +4–8% | Best return is mid-spec; bespoke kitchens rarely return cost in full |
| New bathroom(s) | +3–5% per bathroom | High buyer priority deteriorated bathrooms suppress offers significantly |
| Full refurbishment (non-structural) | +12–22% | Depends on starting condition neglected properties see the highest uplift |
| Structural refurbishment (layout change) | +15–30% | Open-plan living commands a strong premium in London family markets |
| Full specification / luxury finish | +10–20% | Lower ROI than mid-spec; premium finishes are valued less by the market than functionality |
| Energy efficiency upgrades (insulation, heat pump) | +3–7% | Growing buyer priority EPC rating is increasingly scrutinised |
The strongest financial case for a full refurbishment is when purchasing a neglected property at a discount, refurbishing it, and either selling or remortgaging at the improved value. In London’s prime markets, a well-executed refurbishment of a period property can add £150,000–£400,000 in value on a property worth £800k–£1.5m making it one of the highest-returning capital expenditures available to homeowners.
How long does a full house refurbishment take?
Programme length depends on scope, property size, and whether the property needs to be vacated. For a London refurbishment project, plan for the following indicative timelines:
| Scope | Property size | Typical programme |
|---|---|---|
| Light / cosmetic refurbishment | 1–2 bed flat | 6–10 weeks |
| Light / cosmetic refurbishment | 3–4 bed house | 10–16 weeks |
| Full refurbishment (non-structural) | 1–2 bed flat | 12–18 weeks |
| Full refurbishment (non-structural) | 3-bed terraced house | 18–26 weeks |
| Full refurbishment (non-structural) | 4–5 bed house | 24–36 weeks |
| Structural refurbishment | Any | Add 6–14 weeks for structural works, planning, and steel |
| Listed building refurbishment | Any | Add 12–24 weeks for consent and heritage-compliant methods |
The biggest causes of programme overrun on London refurbishment projects are: discovering asbestos or structural defects during strip-out, late decisions on specification by the homeowner, delayed delivery of long-lead items (bespoke joinery, imported sanitaryware), and waiting for building control sign-offs. Build a 20% time buffer into your accommodation plan.
Why do full house refurbishment quotes vary so much in London?
It is normal to receive quotes for the same project that differ by £30,000–£100,000 or more. Before assuming the lowest quote is the right choice, understand why they differ:
- Scope interpretation: Builders price what is written down. If the brief is vague, one builder includes kitchen appliances, another doesn’t. One includes plastering, another prices separately. Always use a detailed schedule of works.
- Subcontractor reliance: Main contractors who manage specialist subcontractors (electricians, plumbers, plasterers) build in a management margin. Builders who directly employ trades tend to quote lower but carry different risk profiles.
- Overheads and insurance: A properly insured, VAT-registered contractor with public liability, employer’s liability, and JCT contract management will cost more than a cash-in-hand trader for good reason.
- Material quality assumptions: A quote based on budget sanitaryware and standard paint will look very different from one based on Hansgrohe and Farrow & Ball. Ensure all quotes are based on the same specification.
- Margin and availability: A builder who really wants the job quotes tight. A builder who is busy quotes with more margin. A quote that is significantly lower than two others is often a signal of underestimation rather than efficiency.
How to reduce full house refurbishment costs in London
There are legitimate ways to bring costs down without compromising quality:
- Phase the work: If budget is constrained, prioritise structural and services in Year 1 (rewire, replumb, structural changes) and follow with decoration and finishes in Year 2. The structural work is harder to do later; the paint colour is not.
- Specify mid-market: The difference between a £3,000 kitchen and a £15,000 kitchen is mostly aesthetic, not functional. Mid-spec kitchens from brands like Howdens or IKEA with quality worktops deliver 80% of the result at 30% of the cost.
- Supply your own materials: Ask if the builder will accept homeowner-supplied materials for fixtures and fittings. Buying sanitaryware, tiles, and appliances yourself removes the builder’s markup (typically 15–25%) and gives you full specification control.
- Avoid peak season: Builders are busiest in spring and early summer. Projects starting in September–November often achieve better pricing and faster scheduling.
- Choose an outer London builder: Quality London renovation builders from outer boroughs will take on inner-London work at lower rates than contractors based in SW3 or W8. Check references and previous projects rather than relying on postcode as a quality signal.
- Get three competing quotes: The spread between quotes gives you real market data. Use the lowest as a negotiating baseline for your preferred contractor, not as a default selection.
- Reduce scope creep: Every change instruction mid-project costs disproportionately more than if priced upfront. Lock in the schedule of works before work begins. Full House Refurbishment Cost London
How to finance a full house refurbishment in London
Very few homeowners fund a £100,000–£200,000 refurbishment from savings alone. These are the main financing routes available in 2026:
| Finance option | Best for | Key considerations |
|---|---|---|
| Remortgage / further advance | Homeowners with equity; long-term owner-occupiers | Lowest interest rate; requires sufficient equity and passing affordability assessment |
| Second charge mortgage | Those who don’t want to disturb their main mortgage | Higher rate than first charge; retains existing mortgage deal |
| Bridging finance | Investors; purchase + refurbish + sell/remortgage | Short-term (6–24 months); high rates (0.6–1.5%/month) but fast to arrange |
| Renovation mortgage | Purchase of uninhabitable property | Released in stages against completed work; requires specialist lender |
| Unsecured personal loan | Smaller cosmetic projects (under £30,000) | No equity required; higher rates; 5–7 year term typical |
If you are purchasing a property specifically to refurbish, always factor refurbishment costs, finance costs (bridging interest, arrangement fees), professional fees, and a contingency into your purchase price calculation before committing. Many London investors use a simple rule: the post-refurbishment value minus all costs (purchase + stamp duty + refurb + finance + professional fees + selling costs) should leave at least 20% profit margin.
How to compare full house refurbishment quotes in London
Comparing three quotes for a complex project requires more than looking at the bottom-line figure. Use this checklist when reviewing each quote:
- Is it an itemised schedule of works or a lump sum? An itemised quote lets you see exactly what is and isn’t included. A lump sum with no breakdown is very difficult to query or negotiate.
- Are materials specified? “Kitchen units” means nothing without the brand and range. “Flooring” means nothing without the material and grade. Ask for product references or allowances per m².
- Does it include VAT? Confirm whether figures are ex-VAT or inc-VAT; a 20% difference matters enormously on a £150,000 project.
- What is the payment schedule? Standard terms are 10% deposit, then staged payments against completed work. Avoid contractors who demand more than 30% upfront or who require payment before stages are signed off.
- What warranties are offered? Electrical work (NICEIC certificate), gas work (Gas Safe certificate), and structural work (backed by structural engineer’s sign-off) all carry formal certifications. Ask what workmanship warranty the contractor provides beyond statutory minimums.
- Who is doing the work? Ask the main contractor which elements they self-perform versus subcontract, and request that subcontractors are confirmed in writing before work begins.
Full house refurbishment London: frequently asked questions
Q – How much does a full house refurbishment cost in London per m²?
Answer: A full-house refurbishment in London costs £1,200–£1,800 per m² for a standard non-structural scope, or £800–£1,100 per m² for a light cosmetic refurbishment. High-spec work ranges from £1,800–£2,500+ per m². These figures include 20% VAT and reflect London 2026 contractor rates.
Q – How long does a full house refurbishment take in London?
Answer: A full refurbishment of a 3-bed London terraced house typically takes 18–26 weeks on site. This allows for strip-out (2–3 weeks), first-fix services (4–6 weeks), plastering and drying time (4–6 weeks), second fix and finishes (6–8 weeks), and decoration and snagging (3–5 weeks). Structural works, planning permission, or listed building consent add to this programme.
Q – Do I need planning permission for a full house refurbishment?
Answer: Most internal refurbishment work does not require planning permission. However, you will need it if you are making external changes in a conservation area, altering a listed building, or changing the use of the building. Building regulations approval is required for structural changes, full rewires (Part P), new boilers (Gas Safe), and certain other works. Your architect or builder should advise on the specific requirements for your property and borough.
Q – What is the difference between a refurbishment and a renovation?
Answer: The terms are used interchangeably in the UK market, though “refurbishment” tends to imply restoring or improving an existing building, while “renovation” can suggest a more transformative change. For planning and building regulations purposes, the distinction matters less than the specific works involved. Both terms are treated identically by builders and tradespeople.
Q – Should I move out during a full house refurbishment?
Answer: For a full refurbishment, particularly one involving rewiring, replumbing, and replastering, you should expect to vacate the property for the duration of works. Living in a property during a full refurbishment significantly slows the programme, increases costs (as trades work around you), and makes the quality of finish harder to achieve. Budget for alternative accommodation of 4–7 months for a 3-bed London house.
Q – Is VAT charged on house refurbishment in London?
Answer: Yes, most refurbishment work is subject to VAT at 20%. The reduced rate of 5% applies if the property has been empty for two years or more. Listed buildings and properties being converted from commercial to residential may qualify for zero-rate VAT on eligible works. As a homeowner refurbishing your own residence, you cannot reclaim VAT. All figures in this guide include VAT at 20% unless stated otherwise.
Q – What contingency should I allow for a full house refurbishment?
Answer: The industry standard is 10–15% for new builds and 15–20% for full refurbishments. For Victorian or Edwardian properties in London, where hidden defects (asbestos, damp, failing wiring, structural issues) are commonly discovered during strip-out, budget a 20% contingency as a minimum. On a £150,000 project, that is £30,000 held in reserve and not committed to any contractor.
Q – How do I find a reliable builder for a full house refurbishment in London?
Answer: The most reliable method is a personal referral from someone who has used the builder on a similar project, followed in person. If referrals aren’t available, use a vetting platform that checks insurance, references, and previous work, not just a directory listing. For a project of this scale, always meet the main contractor in person, visit a completed project if possible, and get at least three quotes to benchmark pricing. Avoid contractors who cannot provide verifiable references for comparable London refurbishment projects.
Q – What is a schedule of works, and do I need one?
Answer: A schedule of works is a room-by-room, trade-by-trade written description of all the work to be carried out. For a full house refurbishment, it is essential, not optional. Without it, each builder is pricing a different project, making quote comparison meaningless. It also forms the basis of your contract with the builder, protecting both parties if disputes arise about what was included. An architect or project manager will produce this as part of their fee; on simpler projects, you can produce a basic version yourself using the trade breakdown in this guide as a framework.
Q – Does a full house refurbishment increase the value of my London property?
Answer: Yes, in most cases. A full non-structural refurbishment typically adds 12–22% to property value, while a structural refurbishment with layout improvements can add 15–30%. The key risk is overcapitalising: spending more on refurbishment than the market ceiling in your street or borough will allow you to recover at sale. In London’s prime markets (Kensington, Chelsea, Islington, Hampstead), the ceiling is high enough that even high-spec refurbishments typically deliver strong returns. In outer London markets with lower price-per-m² ceilings, be cautious about luxury finishes.
