Property Renovation London – Full House & Flat Renovation

What affects the cost of a London property renovation

The per-square-metre benchmarks above are a starting point, not a quotation. The final figure depends on condition and scope: how much has to be stripped back, whether the wiring, plumbing and heating are replaced in full, and whether walls come out and need steels and structural calculations.

London-specific factors move the number too: parking suspensions and skip licences on residential streets, restricted working hours and licence-to-alter conditions in flats, party wall matters where work affects a shared wall, conservation area or listed building constraints, and the access a terrace or upper-floor flat allows for materials and waste. Specification and lead times for kitchens, bathrooms, windows and joinery complete the picture. We set each of these out in the written quotation after a site visit.

Houses and flats across London

Renovating a Victorian or Edwardian terrace usually means dealing with solid walls, original timber floors and decades of piecemeal alterations. Mansion-block and converted flats bring a different set of constraints: freeholder approval, shared risers, acoustic separation from neighbours and strict working hours. 1930s semis and post-war houses often need full rewiring and heating upgrades alongside the layout changes.

The process stays the same in every case — survey, written scope, quotation, programme, coordinated trades and handover — but the order of work and the approvals are planned around the property type and the street it sits on.

Older London housing stock: what we always check

Victorian and Edwardian houses in London tend to share the same faults: rising or penetrating damp at the base of solid walls, failed lime pointing, overloaded original wiring, lead or steel water pipes, sagging lath and plaster ceilings, and joist notching from decades of pipe runs. Any of these can turn a cosmetic project into a structural one halfway through.

We investigate before pricing so the surprises are on the drawing rather than on the invoice. Where a wall must stay breathable we specify lime plaster rather than gypsum and cement, because trapping moisture in a solid wall causes far more damage than the damp you started with.

Living in it, or moving out?

A full refurbishment with a rewire is genuinely difficult to live through: no power in half the house, no heating for stretches, dust everywhere and daily access for six or more trades. Where clients move out we can compress the programme significantly, because we can run trades in parallel instead of zoning the house. Where you have to stay, we phase floor by floor and keep one working bathroom and kitchen at all times — it takes longer but it works.
