House Refurbishment Kensington

House refurbishment in Kensington is the smaller share of the work. Across the VOA statistical areas of Kensington Abingdon and Kensington Gardens, 15% of homes are houses, 13% terraced and 2% semi-detached or detached, set among white-stucco townhouses and period mansion flats. With 75% of homes in those areas built before 1919, a house that comes up for renewal can have lime plaster, tired sashes and wiring from several decades. We renew the fabric of the whole house without re-planning it, and we settle the street side first: the scaffold licence, van bays and the weekday hours for loud work.

For Kensington, published UK figures put a three-bed house refurbishment at £43,530 to £110,350, and London houses usually cost more, with a London architect allowing £1,800 to £2,200 per square metre before VAT (Checkatrade and Bradley Van Der Straeten Architects, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Kensington: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

What a pre-1919 Kensington townhouse needs when it is renewed

A Kensington townhouse built before 1919 is renewed in its own materials, and the survey sets the order. In a house of that age the fabric to expect is solid brick in lime mortar, lath and plaster ceilings, and timber floors on joists notched by a century of cables and pipes. Hard cement render and gypsum patches trap moisture in that kind of wall, so repairs follow the original materials wherever the old plaster is sound enough to keep. If the house is listed, internal works that affect its character, from plaster to joinery and floors, need listed building consent first.

The order of works in a whole house runs strip, first fix, plaster, second fix and finish. Stripping out shows the joists, the lintels and the state of the stair, and any timber or damp repair is priced from what is found rather than guessed at. First fix covers the full rewire, certified by a registered electrician, and the replumb and heating runs, with gas work done by an engineer on the Gas Safe Register. Lime and lath repairs then need drying time before decoration, and that time sits in the programme from day one.

Housing in Kensington

Kensington has around 9,000 homes on the Council Tax list: 19% post-war, 6% interwar and 75% predate 1919, with 85% flats and 15% houses. Where most homes in Kensington are flats, a whole house is refurbished as one building, with a single intake for the services and one roof to keep sound, which matters here because most homes are flats.

Sash windows, front doors and roofs on a Kensington house

Window work on a Kensington house faces two separate tests, and both are settled before anything is ordered. The council's Householders' Guide to windows states that building regulations apply to all replacement windows, so a new sash has to meet current thermal and safety requirements as well as match the old one. On the planning side, the council has consulted on a Windows Local Development Order to remove the need for separate planning permission to change existing windows in non-listed homes, and your designer checks whether it has been made.

Conservation areas cover more than 73 per cent of the borough, and the Kensington Conservation Area was formed in 1976 by extending and joining separate areas designated in the 1970s. On a house in a conservation area, repairs to the front door, roof slopes, parapets and chimney stacks are best done like for like, and anything that changes the look of the front goes to your designer before the scaffold goes up. The council has also drafted a Local Listed Building Consent Order for windows, but under it similar works to Grade II* buildings, and to those in the highest grade, would still need an application for listed building consent.

Weekday hours for noisy work on a Kensington house

On a Kensington house refurbishment, loud work happens on weekdays only. The Royal Borough's final draft Code of Construction Practice sets permitted hours of 8am to 6pm, Monday to Friday, for noisy works audible at the site boundary, with none on Saturdays, Sundays or public holidays. A terraced house shares party walls on both sides, so the neighbours hear the chasing for a rewire and the hacking off of old plaster as clearly as any demolition, and the programme is written with that in mind.

High impact work has tighter windows still. Demolition and concrete-breaking, which in a house means taking up old screeds, breaking out a hearth or cutting through a floor slab for new services, is restricted to 9am to noon and 2pm to 5:30pm on weekdays. We group those tasks into a few set days near the start, and fill the rest of each day with quieter jobs such as setting out, joinery repairs and first fix in rooms that are already stripped. Keeping those days fixed stops every later trade from sliding.

Scaffold licences and van bays outside a Kensington house

A Kensington house refurbishment that needs a scaffold for the roof, gutters or front stucco cannot put it up until the council has approved a licence in writing. Scaffolding, hoarding, gantries and mobile towers on the public highway each need a temporary structure licence, and no work on the highway may start before that approval. The scaffolder normally applies, and the approval date decides when roof and chimney stack repairs can begin, so we sequence the inside work around it.

Vans and waste need the same forward planning on a residential street. The council suspends parking bays for building or maintenance works where the trades use vans, not cars, so the request names the vans and the days they are needed. If the house has an agreed Construction Traffic Management Plan, the council's Construction Management Team handles suspensions and licences and only issues the suspensions agreed in it. A skip on the road needs its own permission, and bagged waste collected from the front can be simpler on a narrow Kensington street.
