Full House Refurbishment in London: Costs, Sequence and What to Expect

A full house refurbishment typically covers: structural alterations (knocking through walls, installing steel beams, creating open-plan layouts); roof repairs or re-roofing; replacement windows and external doors; a full electrical rewire; a full replacement central heating system and boiler; replacement hot and cold water services; new bathrooms (typically all bathrooms and WCs in the house); new kitchen; plastering (full re-plaster of all walls and ceilings, or skimming over existing plaster); new floor finishes throughout (hardwood, engineered wood, tile, or carpet); full redecoration (walls, ceilings, woodwork); replacement skirting boards, architraves, and internal doors; and external works (front and rear garden, fencing, driveway). A refurbishment differs from a renovation in scope and finish quality — a refurbishment replaces everything; a renovation updates selected elements. A refurbishment differs from a conversion in that it works within the existing structure rather than adding new space.

Full house refurbishment costs in London vary widely depending on the size of the property, the specification level, and the extent of structural alterations. Indicative total costs (all trades, materials, and professional fees): 2-bedroom Victorian terraced flat (75-90m2): £70,000-£120,000 mid-specification; £120,000-£200,000 high specification. 3-bedroom Victorian terraced house (110-130m2): £100,000-£180,000 mid-specification; £180,000-£320,000 high specification. 4-bedroom Victorian semi-detached or terraced house (140-180m2): £130,000-£230,000 mid-specification; £230,000-£400,000+ high specification. Per square metre cost (total all-in, mid-specification): approximately £900-£1,500/m2. High specification: £1,500-£2,500/m2. These figures include: structural engineer fees, building regulations, kitchen, bathrooms, all trades, materials, and contractor margin. They exclude: planning fees and architect fees for any planning-required works; furniture and soft furnishings; landscaping (included as an allowance for basic garden works). The biggest variable in full refurbishment costs in London is the kitchen and bathroom specification — a mid-range kitchen in a 3-bedroom house costs £15,000-£25,000; a bespoke high-end kitchen costs £40,000-£80,000. The cumulative effect of specification choices through the project determines the final cost.

The correct sequence of trades in a full house refurbishment is critical to avoiding rework and damage to later-stage finishes: Phase 1 — Surveys and pre-works: structural survey; drainage CCTV survey; electrical EICR; asbestos survey (if any post-war alterations are present); obtain Building Regulations approval. Phase 2 — Strip-out: clear the property of all furniture; remove kitchen and bathroom fittings; strip out floor finishes; remove ceiling finishes if required; remove old boiler and pipework if replacing whole system. Phase 3 — Structural works: knock through any walls; install steel beams; any structural repair works; temporary propping and removal. Phase 4 — Roof works: any roof repairs, re-roofing, new roof lights, new gutters and downpipes. Phase 5 — First-fix services: full electrical rewire (all cables in routes before boarding); first-fix plumbing (new heating pipework, water supply and waste drainage layout). Phase 6 — Insulation and boarding: floor insulation; roof insulation; wall insulation if specified; board out walls and ceilings (plasterboard). Phase 7 — Plastering: skim coat to all plasterboard; lime plaster to any solid brick walls being replastered. Phase 8 — Windows and external doors: replacement windows and doors (typically installed after plastering to avoid damage to new frames during wet trades). Phase 9 — Second-fix services: radiators and heating controls; sanitary ware and kitchen plumbing; electrical sockets, switches, consumer unit, and light fittings. Phase 10 — Joinery: skirting boards, architraves, internal doors and linings, built-in joinery. Phase 11 — Kitchen and bathroom fit-out: kitchen installation; tiling; bathroom installation. Phase 12 — Floor finishes: hardwood floors, engineered floors, tiles. Phase 13 — Decoration: full painting and decorating. Phase 14 — Snagging and completion.

A full house refurbishment is best managed by a principal contractor who coordinates all the trades. The alternative — engaging multiple subcontractors directly — is lower cost in theory but requires the homeowner to manage the sequencing, the interfaces between trades, the material procurement, and the quality control. For projects of this scale, most homeowners find that the time and stress of self-managing trades outweighs any cost saving. A principal contractor charges a management margin (typically 15-25% of the trade costs) but provides: a single point of accountability; coordinated sequencing; management of the programme; procurement of materials; quality control; and a single contract for the whole scope. For full house refurbishments, the most important quality and protection measure is a clear, detailed scope of works agreed in writing before work starts, with a payment schedule tied to defined stages of completion. Never pay more than 20-30% of the total project cost in advance — stage payments should follow completed stages, not advance the contractor's working capital.

A full house refurbishment is incompatible with continued occupation — the property will be without power, heating, sanitation, and a functioning kitchen for extended periods. Most London homeowners arrange to live elsewhere during the main works phase. Options for the refurbishment period: staying with family or friends (free but puts pressure on relationships, particularly if the project overruns); short-term rental of a furnished flat (typical cost in London: £1,500-£3,000/month for a 1-2 bedroom property); serviced apartment (higher cost but more flexible on contract duration); or, where phasing is possible, living in one part of the house while the other is refurbished (only practical in larger 4+ bedroom houses where a self-contained area can be maintained). Budget for temporary accommodation as part of the overall project cost — for a 4-month refurbishment of a 3-bedroom London house, temporary accommodation at £2,000/month is an additional £8,000 to the project budget. Storage of furniture: a removal storage unit for the duration of the refurbishment typically costs £200-£600/month for a 3-bedroom house's contents.
