House Refurbishment Costs in London, Surrey, Essex, Kent and Hertfordshire
A comprehensive guide to the true cost of refurbishing a house or flat in London and the South East — covering every trade, every room, genuine 2025 market rates, and how to get a fair quote.
The Real Cost of a House Refurbishment in London
A full house refurbishment in London in 2025 costs between £500 and £1,500 per square metre, depending on specification. A 100m² three-bedroom Victorian terrace will cost between £50,000 and £150,000 from top to bottom.
This wide range reflects specification. A cosmetic refurbishment — repainting, new carpets, replacing dated fixtures — sits at the lower end. A gut-and-rebuild with structural alterations, full rewire, new plumbing, bespoke joinery, and premium finishes sits at the top.
Bathroom Refurbishment Costs
A full bathroom replacement — new suite, tiling, underfloor heating, wetroom waterproofing — costs £8,000–£25,000 in London. A basic like-for-like replacement costs £4,000–£8,000 but rarely delivers the finish that adds value.
Luxury en-suites with bespoke joinery, freestanding baths, and designer sanitaryware (Duravit, Agape, Vitra) range from £20,000–£40,000.
Kitchen Installation Costs
A kitchen fit-out including units, worktops, appliances, plumbing and electrics costs £12,000–£40,000. Kitchen furniture alone varies from £4,000 (flat-pack) to £25,000+ for bespoke cabinetry. Labour for installation is typically £3,000–£6,000 additional.
Electrical Rewiring Costs
A full rewire of a three-bedroom house: £3,500–£5,500. Four-bedroom properties: £5,000–£7,500. Always use an NICEIC-approved electrician. Building Regulations sign-off is mandatory.
Replastering Costs
Skim coat over existing plaster (3-bed house): £2,500–£4,500. Full replastering (remove and replace): £4,000–£7,000. Specialist Venetian plaster or polished cement finishes are priced separately at £80–£150/m².
Painting and Decorating Costs
Professional decoration — prep, primer, two finishing coats on walls/ceilings, skirting and woodwork — costs £1,500–£3,000 for a three-bedroom house. Premium finishes (Farrow & Ball, specialist wallpaper) are additional.
Regional Variations
London rates are 20–35% higher than national averages due to higher labour costs, congestion charges, parking, and longer site logistics. Prime postcodes (SW, W, EC, WC) command a further 10–15% premium for specialist trades.
Outside London — Surrey, Essex, Kent, Hertfordshire — costs are 10–20% lower for standard trades. However, specialist skills (Venetian plaster, polished cement, zinc roofing) carry similar rates regardless of location.
