House refurbishment in Belgravia applies to a minority of the stock. VOA figures for the wider Knightsbridge, Belgravia & Hyde Park area count 29% of homes as houses, 28% as terraced houses and 67% as built before 1919. Belgravia's own housing is stucco-fronted townhouses and mews properties, so renewing a house here means working with lime plaster, deep timber floors, sash windows and services that earlier owners extended in stages. The street outside brings its own rules on noisy hours, scaffold and the width of the pavement.
For Belgravia, 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 Belgravia: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

Stripping back a pre-1919 Belgravia townhouse to its fabric
Stripping a Belgravia townhouse back shows what each room is made of before any new finish is chosen. In houses of that age, which make up 67% of homes across the wider Knightsbridge, Belgravia & Hyde Park area, walls are often lime plaster on brick or lath, and gypsum patching over them tends to crack and hold damp. Where the house is on the statutory list, taking out original plaster, cornices or joinery needs listed building consent first, which covers work inside the house as well as outside, and the owner or designer obtains it. We open a sample area, agree with you what is repaired in lime and what is renewed, and price the plaster on what the walls really are.
Joists and stairs are checked while the floors are up. In a Belgravia house of this age, earlier plumbers and electricians have often notched joists for pipe and cable runs, and a tall stair carries its loads down through several storeys. We record the defects, agree repairs with you and, where a joist or trimmer needs more than a like-for-like repair, bring in the structural engineer we appoint. Original joinery such as shutters, architraves and skirtings is numbered and set aside or repaired in place, so the finished house keeps the details its age gives it.
Housing in Belgravia
On the valuation list the Knightsbridge, Belgravia & Hyde Park statistical area counts about 6,020 homes, 71% flats and 29% houses; 67% predate 1919, 9% are interwar and 23% post-war. Where most homes in Belgravia 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.
Rewiring, replumbing and heating a whole Belgravia house
A Belgravia house refurbishment renews the services from the bottom of the house to the top in one pass, so no floor is lifted twice. The rewire is designed and certified by a registered electrician, and gas work on the boiler, flue and supply is carried out by an engineer on the Gas Safe Register. Heating pipework is renewed where old runs are corroded or buried in solid floors, and the boiler or cylinder position is settled before first fix. In a tall terraced house the risers are planned as one vertical route rather than room by room.
The paperwork closes the job as much as the plaster does. Westminster City Council runs its own building control service and must be told the start date at least 2 days before work begins, on the application form or by email. Its policy is to issue a completion certificate only once the fees due are paid and the relevant electrical and gas certificates have been supplied. We collect those certificates from the registered installers as each stage finishes, so the Belgravia file is complete at handover rather than chased for weeks afterwards.
Windows, roofs and stucco in the Belgravia conservation area
Belgravia was first designated as a conservation area in 1968 and extended in 1977 and 1981, and that shapes how the outside of a house is refurbished. In a Westminster conservation area some alterations that would not need permission elsewhere do need planning permission, so a change of window pattern, front door or roof covering is checked with your designer before it is priced. Repairing sashes like for like, renewing cords and weights and fitting draught strips keeps the original frames in place, which is the simplest route through the rules.
Roofs, gutters and chimney stacks on a Belgravia house are repaired as the survey requires, using one scaffold for all of them. Where a stack is shared with next door, repairing or rebuilding it needs a party wall notice, which you as building owner serve before that part starts; the work then goes ahead on the neighbour's written consent or a surveyor's award. Westminster has removed permitted development rights in eight of its conservation areas, and its audits pick out unlisted buildings of merit, so your designer confirms which rules apply to the address before any roof or facade change. On a stucco front, cracked render is cut back and repaired to match rather than patched in cement. Where roof elements are renewed, insulation goes in to meet Part L, which cuts heat loss through the top floor.
Scaffold, skips and working hours on a Belgravia street
A Belgravia house is refurbished from the street, so the pavement is part of the plan. Westminster needs a temporary structure licence for scaffolding, construction fencing or a cherry picker placed in the road or on the pavement, and its site guidance keeps the footway at least 1.5m wide around the works. On a mews or a narrow terrace street that decides where the scaffold stands, where a skip or grab bags can go and how deliveries arrive. We survey the frontage early and line up the scaffold licence dates with the scaffolder before the start.
Noisy work in Westminster runs Monday to Friday 8am to 6pm and Saturday 8am to 1pm, and anything noisy outside that window needs a Section 61 application at least 28 days ahead. An empty Belgravia house can go through strip-out, first fix, plaster, second fix and finishes floor by floor inside those hours. If you are living in the house, we phase the work so one part stays usable, with a working bathroom and a kitchen or temporary kitchen, and the dustiest stages sealed off behind screens.

The GS Renovation Difference in Belgravia
A Belgravia house owner needs one firm to run the whole refurbishment in the right order: strip-out, repairs to the old fabric, first fix, plaster, second fix and decoration. We give a written quotation after a site visit, bring in the registered electrician, the gas engineer and the structural engineer we appoint where the work needs them, and keep every certificate together for handover. The founder has more than thirty years of hands-on experience, and finding and pricing hidden defects in an old house depends on exactly that.
- A written scope and programme agreed before work starts
- First fix cabling on each floor inspected by the electrician before the walls are closed
- Every wall of the house tapped and every circuit tested before the refurbishment is priced

FAQ
Frequently Asked Questions about House Refurbishment Belgravia
What should I budget for a full house refurbishment in Belgravia?
Start from the published UK range of £43,530 to £110,350 for a three-bed house (Checkatrade, 2026) and expect a London house to sit higher. Add a contingency for what only shows once plaster and floors are opened. The itemised quote after the Belgravia survey shows each trade separately, so the work can be phased if the total is more than you want to spend at once.
Should a pre-1919 Belgravia house be replastered in lime or gypsum?
Lime, where the wall behind is solid masonry or lath that was first plastered in lime. Walls of that age move moisture through them, and gypsum over damp solid brick can trap it and fail. Across the wider Knightsbridge, Belgravia & Hyde Park area 67% of homes were built before 1919, so a Belgravia house is likely to fall on the lime side of that line. We test what is on the wall and use modern plaster only where it will not cause trouble.
Do you need a licence for scaffold outside a Belgravia townhouse?
Yes, where the scaffold stands in the road or on the pavement. Westminster requires a temporary structure licence for scaffolding, fencing, cranes or cherry pickers on the highway, and its guidance keeps at least 1.5m of footway clear around the works. Scaffold standing wholly on private land, such as a front area behind railings, does not need that highway licence.
What hours can noisy work run on a Belgravia house refurbishment?
Monday to Friday 8am to 6pm and Saturday 8am to 1pm are Westminster's normal hours for noisy construction. Noisy work outside them needs a Control of Pollution Act Section 61 application at least 28 days before works start. We plan the strip-out and chasing inside the normal window and keep quieter trades for the edges of the day.
Do sash window repairs need permission in the Belgravia conservation area?
Not usually for a like-for-like repair of existing sashes, which leaves their appearance unchanged, unless the house is on the statutory list and the repair touches original fabric. Belgravia has been a conservation area since 1968, and in a Westminster conservation area some alterations that would be free elsewhere need planning permission. Replacing windows in a new pattern or material is therefore checked by your designer before it goes into the scope.
When does Westminster issue the completion certificate after a house refurbishment?
Only once all fees due have been received and the relevant electrical and gas certificates have been supplied, under Westminster's stated policy. That makes the certificates from the registered electrician and the gas engineer part of the finish, not an afterthought. We gather them as each stage completes so nothing holds up the certificate at the end.
Can the family stay in a Belgravia house during a refurbishment?
Often yes, if the work is phased. We keep one floor or one end of the house usable, with a working bathroom and a kitchen or temporary kitchen, while the rest is stripped and rebuilt behind dust screens. A full rewire and replumb does mean short periods without power or water, which we schedule with you in advance.
Do you refurbish houses before a sale or after a probate?
Yes. For a sale or an estate we agree a scope aimed at what a buyer's surveyor looks at first: wiring, heating, damp, the roof and the kitchen and bathroom. We hand over the certificates for the work carried out, which the conveyancer will ask for, and work to a completion date where the programme allows it.
Does Westminster need to know when a house refurbishment starts?
Yes, where the work needs building control. Westminster accepts applications online as full plans, building notice or regularisation, and the start date must be given on the form or by email at least 2 days before work begins. Painting and decorating are not notifiable works, and like-for-like repairs on their own are not usually notified either, so the survey sorts the scope into the two groups.
