House Refurbishment Old Street

House refurbishment in Old Street is a small, specific job, because the valuation list puts houses at 1% of homes here and flats at 99%. The houses that exist are terraced, and 16% of all homes in the area were built before 1919. If yours is one of them, a refurbishment means renewing the wiring, plumbing, heating, plaster, joinery, windows and roof of a whole house without re-planning its rooms. If it lies in the St Luke's conservation area, which straddles Whitecross Street and Old Street, check whether an article 4 direction reaches its front windows and doors.

For Old Street, 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 Old Street: 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 an older Old Street terrace needs when it is refurbished

An older Old Street house is refurbished from the fabric outwards, and the valuation list shows why its age matters: 16% of all homes here, flats included, predate 1919, 5% date from between the wars and 76% from after 1945. A house from before 1919 commonly has lime mortar, lath and plaster ceilings, suspended timber floors and voids that have carried several generations of wiring and pipework. We open those up carefully, record what is there, and keep breathable finishes on solid walls rather than sealing them with gypsum and plastic paint, which traps moisture.

The services are renewed as one sequence rather than room by room. A registered electrician certifies the full rewire, a registered gas engineer handles the boiler and any gas appliances, and the heating pipework and radiators are replaced while the floorboards are up. Joists notched by earlier pipe runs are repaired or strengthened, the stair is eased and refixed, and sash windows are overhauled or renewed. Only then do the plasterers return, using lime where the walls need it, before second fix, joinery and decoration.

Housing in Old Street

Take the 6,800 or so homes the valuation list gives Old Street: 99% flats, 1% houses, 16% from before 1919, 5% interwar and 76% post-war. A whole house in Old Street is refurbished as one building, roof down, which matters here because most homes are flats.

Conservation area rules on windows, doors and roofs in Old Street

Before a window, door or roof covering on an Old Street house is changed, find out whether the house sits in a conservation area and whether an article 4 direction applies. Islington says there are currently 42 conservation areas in the borough and that it has removed permitted development rights in 40 of them by article 4 direction. The St Luke's conservation area straddles Whitecross Street and Old Street and is described by the council as an important surviving part of historic Finsbury.

In Islington's article 4 conservation areas, planning permission may be needed for minor alterations such as changing external doors and windows or painting brickwork on the outside. A house covered by an Article 4 direction needs householder planning permission to install or replace front windows or doors. That sets the order of work: repairs to existing sashes, doors and brickwork go ahead while any replacement waits for the owner's consent, and roof and chimney repairs are specified like for like. Pruning or felling a tree in a conservation area needs six weeks written notice to the council, which matters when scaffold goes up beside one.

Hours, skips and parking for an Old Street house refurbishment

Noisy work on an Old Street house refurbishment runs inside Islington's permitted hours: 8am to 6pm Monday to Friday and 8am to 1pm on Saturdays, unless the council approves otherwise. Stripping out, chasing walls for the rewire and lifting floors are the loud stages, so we put them early in the week and keep plastering, joinery and decorating for the later days. On a terrace the party walls carry noise to both neighbours, so we tell them the loud days in advance.

A whole house produces far more waste than a flat, and on an Old Street road it has to leave from the kerb. A skip on the road needs a licence from the council, any other obstruction such as scaffolding or stored materials needs a highways licence, and Islington asks for scaffolding licence applications at least 10 working days in advance. Most parking bay suspensions must be applied for at least 14 days before they begin, and on City Road, a red route, permission comes from Transport for London. Where a skip will not fit we use bagged waste on a set collection day.

Occupied or empty: programming an Old Street house refurbishment

Whether you stay in an Old Street house during the refurbishment changes the programme more than any other choice. An empty house is stripped in one go, then first fix, plaster, second fix and finishes follow floor by floor, which is the shortest route. If you live in it, we phase the work so one bathroom, a working kitchen and a bedroom stay usable, and services are isolated only in planned windows. Renewing a roof covering, replastering external walls or replacing windows can bring Part L insulation requirements into play for those elements, so we price that from the start.

The building control route is simpler for a house than for a flat. Islington says a building notice cannot be used for residential premises with common areas, which a single house does not have, and under a building notice work can start 48 hours after the notice is given with the correct fee. Islington Council issues completion certificates after satisfactory completion of works in line with the building regulations and full payment of fees. For a landlord re-letting the house, a pre-sale job or executors preparing a probate sale, we gather those certificates with the electrical and gas records into one pack.

• Lime plastering on solid walls and lath and plaster ceiling repairs
• New boiler, cylinder and radiators sized to every room, fitted by a Gas Safe registered engineer
• Sash boxes overhauled with new cords, parting beads and brush seals
