Why renovation costs more in London
London labour rates, controlled parking and access, the prevalence of period and converted homes, and higher waste-disposal costs all push prices above the national average. A realistic London quote reflects those local conditions — not a generic UK figure.
What decides the price of your renovation?
Five things move a renovation budget more than anything else. We price each of them transparently, from your specification.
The single biggest variable. Off-the-shelf units and mid-range tiles cost a fraction of bespoke cabinetry, natural stone and premium brassware. We price to your spec, not an average.
Moving walls, adding steels, relocating plumbing or knocking through for open-plan living adds engineering, building control and labour that a like-for-like refit does not.
Period terraces and flat conversions often need extra care — replastering, levelling old floors, sound insulation and party-wall coordination — over a modern property.
Controlled parking zones, narrow streets, upper-floor flats and concierge access windows all affect deliveries and labour time across inner London boroughs.
Old wiring, failing plumbing, damp or rot found on strip-out can need putting right. We flag likely risks upfront and only proceed on agreed, priced variations.
Where specialist trades change the number
Two lines on a renovation budget are consistently mispriced, and both of them are finishing work — the part of a project nobody sees being done but everybody looks at afterwards.
The first is plastering. It sits between first fix and decoration, and the flatness of the wall it produces sets the quality of every coat of paint applied to it. A cheap skim cannot be rescued downstream — it shows under raking light for the life of the wall, and a decorator charging by the day will spend that day filling instead of painting. Where a project needs external rendering as well as internal skimming, a dedicated firm such as London Plastering Service handles both, and specialists of that kind are typically booked several weeks ahead — which is why the plastering date, not the plastering price, is what actually moves a programme.
The second is the wet rooms. A bathroom compresses drainage falls, electrical zones, waterproofing and tiling setting-out into roughly four square metres, and the elements that fail are the ones sealed behind tile. That is why bathrooms are quoted as a package rather than a day rate, and why some homeowners prefer a single accountable supplier for that room alone — firms such as London Renovate deliver bathroom design, supply and installation together for exactly that reason. Whichever route you take, the question worth asking is not the price per square metre but who is tanking the wet zone and which waterproofing system they are using.
