Full House Renovation Cost London 2026: What to Budget

Planning a full house renovation in London? Here's what it actually costs in 2026 — room by room, finish tier by tier, with real numbers from completed projects.

By Vladimir Castravet··

A full house renovation in London costs £1,200–£2,800 per m² in 2026. For a typical 3-bedroom Victorian terrace of around 120m², that is £145,000–£340,000 for a full gut renovation — the spread is specification, not surprise. The renovation cost hub breaks it down by area, the estimator prices your own house room by room, and the delivered projects show what each tier actually looks like finished.

A full house renovation is the biggest single investment most London homeowners will make. Get it right and you transform a dated property into exactly the home you want. Get it wrong — wrong contractor, vague contract, no itemised scope — and costs escalate unpredictably.

This guide sets out what full renovations actually cost in London in 2026, based on 2VP’s completed projects.


Full Renovation Costs per m² (London 2026)

Specification TierCost per m²3-bed terrace (~120m²)

Signature£2,200 – £2,800£264,000 – £336,000

These are shell and core + fit-out costs: structural work, MEP services, kitchen, bathrooms, floors and decoration. External works and extensions are additional.


What the Three Tiers Mean

  • Floors: engineered oak 14mm (mid-range)
  • Walls: plasterboard and skim, trade emulsion finish
  • Windows: PVC-U or aluminium powder-coat

Balanced (£1,600–£2,000/m²)

The most common spec for 3–5-bed family renovations in inner London:

  • Bathrooms: premium sanitaryware (Hansgrohe, Villeroy & Boch, Antonio Lupi tiles)
  • Floors: engineered wide-plank oak or polished concrete
  • Windows: Crittal-style or high-performance aluminium
  • Joinery: painted MDF or hardwood built-ins throughout

Signature (£2,200–£2,800/m²)

The Hidden Costs of a London Renovation

Party wall

A Victorian terrace renovation touching any wall adjacent to a neighbouring property triggers the Party Wall Act. Costs: £800–£2,500 per neighbour, depending on whether a surveyor is required.

Asbestos survey

Properties built before 2000 require an asbestos survey before any notifiable demolition or building work. Cost: £300–£600. If asbestos is found and needs removing: £1,500–£8,000 depending on type and extent.

Scaffolding

Any work on a terrace requires scaffolding. For a full terrace renovation, expect £2,000–£4,500 for a standard licence on a residential street.

Hidden defects

Old London houses regularly conceal damp, defective drainage, inadequate foundations or rotted timbers. 2VP includes a 10% contingency in every JCT contract to handle what the pre-contract survey can’t see. We don’t pass those on to you as unexpected variations.


How 2VP Prices a Renovation

Every 2VP renovation quote is based on:

  1. Measured survey — we measure every room, wall and ceiling area precisely
  2. Specification workshop — you choose your finishes from our specification sheets; we price exactly what you’ve chosen
  3. JCT contract — the scope you sign is the scope we price, and any change to it is costed and signed by you before the work happens
  4. Insurance-backed guarantee — a HomePro 10-year guarantee is available on request; ask us to price it with the rest

That is a different thing from a builder who says “probably around £150k, we’ll know more once we start”. A price against a measured scope can be held to; a guess cannot. What no honest builder can tell you is that the final figure will never move — it moves when the scope moves, which is why every change is priced and signed before anyone starts it.


What to Do Before Appointing a Contractor

  1. Get three comparable quotes — the same specification, the same contract type
  2. Ask for JCT contract or equivalent — not a letter, not an email, not a “quote sheet”
  3. Check Companies House — verify the company exists and has filed accounts
  4. Check insurance — ask for a copy of public liability and employers’ liability certificates
  5. Ask for references — not testimonials, not “we’ll send you photos” — speak to two previous clients

2VP is registered at Companies House (14122250), fully insured, and our clients are happy to speak to prospective new clients.

★★★★★
As a structural engineer, I've collaborated with 2VP Projects Ltd on several residential projects in London. Their attention to detail, proactive site management, and clear communication make every stage—from design to execution—smooth and efficient. It's rare to find a contractor who values both precision and professionalism at this level. A truly reliable partner.
