Full refurbishments and whole-house renovations in Westminster. Trusted, professional, 30+ years' hands-on experience.
GS Renovation carries out whole-house refurbishments across Westminster, from Regency townhouses in Belgravia to period mansion flats in Marylebone and Pimlico. With over 30 years in W1, W2, SW1, WC2, NW8 and W9, we manage rewiring, replumbing, replastering and reconfiguring dated layouts with a single team, restoring period features while bringing tired interiors up to date.

A full renovation of a Westminster townhouse runs across several floors, and sequencing is everything. We strip back, rewire and replumb the whole house, then replaster and reconfigure layouts that no longer suit modern living, opening cramped lower-ground floors or reworking a warren of small rooms into generous spaces. Where a wall comes out, our engineer sizes the steel and building control signs it off.
These Georgian and Regency homes carry original cornicing, joinery, fireplaces and staircases that give the borough its character. In conservation areas and listed properties across SW1 and W1, we restore and protect those features rather than lose them, matching mouldings and reinstating detail so the finished house reads as authentically period while working as a comfortable modern home.
The value of one team shows most on a large refurbishment. We sequence structural work, first-fix services, plastering, kitchens, bathrooms and decoration so trades follow each other cleanly rather than clashing. On a Paddington or Marylebone project that might run several months, that coordination keeps the programme tight and the site tidy, which matters when the house sits on a busy Westminster street.
For mansion flats in NW8 and W9, refurbishment works within leasehold rules. We coordinate with the freeholder and managing agent, respect building-management hours and access, and pay close attention to sound insulation between flats when floors come up. Every notifiable electrical and plumbing change is carried out to building regulations and certified, so your renovation is compliant as well as beautifully finished.
Westminster homeowners choose GS Renovation because a whole-house refurbishment needs one accountable team, not a string of separate trades. We handle structure, services, plaster, joinery and finish together, protect period detail in listed and conservation-area homes, and work cleanly in occupied streets. Thirty years across the borough means the sequencing, the compliance and the craftsmanship are all in hand.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
We price each Westminster project individually, because the cost of home renovation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. As a rough guide, home renovation in London ranges from roughly £40,000 to £150,000 or more for a full refurbishment (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
How long home renovation takes in Westminster depends on the size of the job, but we always agree a programme before starting and stick to it, keeping you informed from the first day to the last.
GS Renovation's team brings over 30 years of hands-on experience to home renovation and wider building work across Westminster and the surrounding area. We offer free quotes, a dedicated project manager, full insurance, building control compliance where required, and comprehensive aftercare.
Most internal home renovations in Westminster do not need planning permission, though building regulations apply to structural, electrical and plumbing work. Extensions or external changes may need permission or fall under permitted development. We handle building control and any applications for you.
Yes. A large share of Westminster's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each home renovation around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
Internal renovation of a Marylebone flat does not need planning permission, since you are refurbishing inside rather than altering the exterior. The electrical and plumbing work is notifiable under building regulations and we certify it. If the building is listed, some internal changes may still need listed building consent, and a leasehold flat will need the freeholder's licence to alter. We check both before starting.
Absolutely. Our team works right across Westminster and the W1 area and neighbouring parts of Central London. Get in touch on 07472 424 226 to check coverage for your address.
