GS Renovation carries out whole-house refurbishments across Harlesden, bringing tired Victorian and Edwardian terraces in NW10 up to modern standards while keeping their character. One team handles the rewiring, replumbing, replastering, structural changes and finishes, sequenced so the project runs in the right order.
In Harlesden, a full house refurbishment typically costs £40,000 to £150,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Harlesden: we carry the structure, services and finishes as one contract.
The two rooms that cost the most have their own pages, with prices: kitchen renovation in Harlesden and bathroom renovation in Harlesden. With 83% of homes in Harlesden flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Full refurbishment of Harlesden period homes
Many Harlesden terraces have been divided, patched and re-serviced piecemeal over the decades, leaving dated layouts, tired wiring and mixed plumbing. A full refurbishment lets us strip back, rewire and replumb the whole house on one consumer unit and one heating system, replaster throughout, and reconfigure the rooms so the property works for how people live now. We plan the sequence so structure comes first and finishes last.
These NW10 houses reward keeping what makes them special. Where cornices, ceiling roses, picture rails, fireplaces and panelled doors survive, we restore and reinstate them rather than lose them, while opening up the plan where it suits the family. We work around the solid-wall construction and the rear closet wing that defines these terraces, marrying the old fabric to new insulation, services and layouts.
Housing in Harlesden
The Council Tax list puts Harlesden at about 6,350 homes, 83% flats against 17% houses; 78% went up before 1919, 4% between the wars and 18% after 1945. Most homes here are flats, and a whole-flat refurbishment in Harlesden works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.
Roofs, age and heritage checks on a Harlesden renovation
A whole-home renovation in Harlesden can reach the roof, and the roof brings in two sets of rules. Recovering a roof is building work in Brent: its building notice route names it alongside creating a bathroom and minor structural changes. Planning is the second test. Where a Brent conservation area article 4 direction applies, planning permission can be needed for replacement of roof tiles. Ask Brent whether the address sits inside the Harlesden Conservation Area, and whether a direction covers it, before a cheaper replacement tile is chosen. Keeping samples of the original tiles makes a like-for-like case much easier to argue.
The age of the stock shapes the programme. With 78% of Harlesden homes built before 1919, a renovation works with solid walls, timber lintels and floors altered by earlier owners, and the sequence has to leave time for what opening up reveals. Brent's own building control service approves plans and inspects work on site, so on a renovation with several notifiable items, one application describing them all is simpler than a string of separate notices raised as each surprise appears. The electrical work is certified separately by the registered electrician.
One team managing the whole NW10 project
Renovating a whole terrace involves trades that have to follow each other in a strict order, from first-fix electrics and plumbing through plastering to the kitchen, bathrooms, joinery and decoration. Running these as separate jobs is where projects stall. We coordinate them under one roof so the plasterer is not waiting on the electrician and the decorator is not painting over unfinished work.
Internal renovation does not need planning permission, but the rewire and any consumer unit change are notifiable under Part P, so they are certified by a registered electrician. Where the refurbishment includes removing a load-bearing wall or a chimney breast, we bring in the engineer and building control for that element. You deal with one point of contact for the entire Harlesden project from strip-out to snagging.

FAQ
Frequently Asked Questions about Home Renovation Harlesden
How much should a Harlesden homeowner set aside for home renovation?
The right sum to set aside for home renovation in Harlesden is fixed after the survey, not before it, and usually falls within £40,000 to £150,000 or more (indicative). Guessing usually means guessing wrong, and the NW10 visit costs nothing. GS Renovation then gives an itemised total including Part P notification for the rewire and Brent Council building control sign-off. Call 07472 424 226 or email info@gsrenovationltd.co.uk.
Do I need planning permission to renovate the inside of my Harlesden house?
No. Internal renovation of your NW10 terrace, including rewiring, replumbing, replastering and reconfiguring rooms, does not need planning permission. New circuits and any consumer unit change are notifiable under Part P and certified by a registered electrician, and if the project removes a load-bearing wall or chimney breast, that element is engineered and signed off by Brent Council building control. External changes, which a conservation area controls more tightly, and internal work on a listed home, are the exception.
Can the whole of my Harlesden flat be rewired and replumbed in one go?
Yes, and it is the best time to do it. Everything runs before plastering, so nothing is chased into finished walls. In converted flats the meter is often in the communal hall and the supply main runs through common parts, so the freeholder may need to agree. A registered electrician certifies the work under Part P.
What sound insulation should go in when renovating a Harlesden conversion flat?
Floors between flats in converted houses often have little sound insulation. When the floor is up, adding mineral wool between joists and a resilient layer under the new floor greatly reduces noise. Your lease may require carpet or acoustic underlay. Ceilings can also be improved with resilient bars and acoustic plasterboard.
How do solid walls and lime plaster affect renovating a Victorian Harlesden home?
Walls built before 1919 are usually solid brick with lime plaster, which let moisture pass through. Replastering with gypsum or sealing with plastic paints can trap damp. The best approach is to patch with compatible materials and only hack off plaster that has failed. With 78% of Harlesden's dwellings dating from before 1919, this applies to many homes.
Should the windows be replaced before the plastering in a Harlesden renovation?
Yes. Fitting windows before plastering means the reveals are made good once, rather than cut back afterwards. If the sashes are being repaired rather than replaced, that also happens before decoration. New frames also go in before any second-fix joinery, so architraves and window boards fit the finished reveal.
How does Brent's Local List affect renovating a Harlesden house?
Brent keeps a Local List of non-designated heritage assets, buildings or structures of architectural or historic interest, so ask the planning team before any external work. Local listing adds no separate consent and does not control internal work. Where planning permission is needed for an outside change, the building's interest is weighed in the decision. Keeping original windows, doors and brick detail is the simplest way to avoid a dispute.
Does renovating a Harlesden flat need anything from Brent beyond the freeholder's licence?
Yes, where the work is notifiable. The freeholder's licence is a private consent under the lease. Brent's own building control service approves plans and inspects work on site for the Building Regulations, and neither replaces the other. In Harlesden 83% of homes are flats, so this pairing is the normal case: a new bathroom, a moved kitchen or a structural change needs both, and a licence may name the completion certificate as a condition.
Should renovation drawings go to Brent before or after the strip-out in Harlesden?
Before, for the parts already known. Brent aims to respond to a full plans application within three weeks, and approved plans stay valid for three years, so an early application does not lapse before the builders arrive. Items uncovered during the strip-out, a rotten lintel or an undersized joist, are added with details from the structural engineer we appoint. Leaving the whole application until after the strip-out means the design is still being settled while the house stands stripped and unheated.
