GS Renovation takes on whole-house refurbishments across Barnet, from the Victorian and interwar houses of Chipping Barnet and New Barnet to the 1930s semis of Finchley, Hendon and Edgware. We manage rewiring, replumbing, replastering and structural changes with one team, sequencing the whole project from strip-out to final decoration.
In Barnet, 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 Barnet: 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 Barnet and bathroom renovation in Barnet. With 50% of homes in Barnet flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Refurbishing interwar houses across Barnet
Many of Barnet's interwar houses still carry their original compartmentalised layout, with small kitchens, separate dining rooms and dated wiring and pipework from decades of piecemeal updates. A full refurbishment lets us reconfigure these rooms for modern life, often knocking through to create open-plan living at the rear while keeping the period character that makes homes around Hampstead Garden Suburb and Mill Hill so sought after.
We strip back to what needs replacing and renew the essentials, a full rewire, new plumbing and heating, fresh plaster and, where the fabric allows, improved insulation. Original features worth saving, such as cornicing, picture rails, panelled doors and cast fireplaces, are protected and restored rather than lost. Everything is brought up to current standards, with new kitchen and bathroom circuits certified by a registered electrician under Part P.
Housing in Barnet
About 160,480 homes are listed for Barnet, and the mix is 50% houses to 50% flats, with 46% built after 1945, 34% in 1919 to 1939 and 20% earlier. Since many homes here are flats, refurbishing a flat in Barnet starts with the freeholder's licence for alterations.
Front boundaries and old solid walls in a Barnet renovation
A whole-house renovation in Barnet can end at the front garden, with a rebuilt boundary wall or new gates for the drive. In Glenhill Close Conservation Area, Barnet's Article 4 direction, approved on 31 July 2002, covers the erection, maintenance, improvement or alteration of a gate, fence, wall or other means of enclosure. There, even rebuilding a failing front wall to a new design needs planning permission first. Price the renovation with the boundary as it stands, and apply separately for any change before a landscaper is booked, so the house is not finished while the front waits on a decision.
20% of Barnet's homes were built before 1919, and renovating one of those calls for a different wall specification from an interwar or post-war house. Solid brick laid in lime was built to take in moisture and give it off again. Cement render outside, or gypsum plaster and vinyl paint inside, traps that moisture, and damp can follow. On a pre-1919 house we keep or repair lime finishes on the external walls and choose insulation that lets the wall dry, and that decision is made before the rewire and replumb are closed in behind new plaster.
One team managing your Barnet renovation
The value of a whole-house project is sequence. We plan structural work first, any steel beams or wall removals signed off by building control, then first-fix services, plaster, kitchens, bathrooms, second fix and decoration follow in the right order. Where wall removal touches the wall you share with a neighbour, a common situation in Barnet's semis, you serve the party wall notices as building owner, and we give you the drawings early so they go out in good time.
Whether it is a property renovation before you move in or a house refurbishment around the family, one team means one point of contact and no gaps between trades blaming each other. We coordinate electricians, plumbers, plasterers, joiners and tilers on a single programme, keeping the site tidy and the work moving whether you stay put or move out during the build. You get clear stages, honest timescales and a finished home that works from top to bottom.

FAQ
Frequently Asked Questions about Home Renovation Barnet
Are there hidden costs with home renovation in Barnet?
The risk of extra cost on home renovation in Barnet sits in what is concealed. GS Renovation lists what the EN5 survey could not inspect, so you know where the figure within £40,000 to £150,000 or more (indicative) might move. What strip-out finds in the wiring and timbers decides the programme, which is why that point is opened up early. Any Barnet Council building control fee and the engineer where the design needs one are priced from the start.
Can you renovate my whole Barnet house while keeping its 1930s character?
Yes. Across Barnet we modernise interwar houses while protecting what makes them special. We restore cornicing, picture rails, panelled doors and original fireplaces where they survive, then rewire, replumb, replaster and reconfigure the layout around them. The result blends open-plan practicality at the rear with the period proportions and detail these Finchley and Mill Hill homes are known for.
Why do the rewire and new pipework come before plastering in a Barnet renovation?
Because both disappear into the walls. Cables are chased into brickwork and pipes run under floors at first fix, then tested and inspected before new plaster seals them in. In a Barnet interwar house where old lath and plaster ceilings are often replaced anyway, doing it in that order means the plasterer covers everything once, instead of patching later.
Should we test for asbestos before stripping out our Barnet 1930s semi?
Yes. Any building from before 2000 can contain asbestos, and Barnet's interwar houses have often been updated over the years with textured ceilings, floor tiles and boarding around old heaters or boilers. A survey before strip-out identifies what is present, and anything that needs a licensed contractor is removed before other trades arrive.
What extra control applies to renovation in Hampstead Garden Suburb, Barnet?
External changes. The suburb is a conservation area, so alterations that change the outside, such as windows, doors, roofs or walls, can need planning permission even where they would not elsewhere. Internal renovation does not, though building regulations still apply to structural, electrical and drainage work. We check what is proposed on the outside before it is ordered.
Does a Barnet whole-house renovation need a party wall notice?
Only if structural work touches the shared wall. In a semi, cutting in beam bearings, removing a chimney breast on that wall or digging close to next door's foundations are all notifiable. Decoration, rewiring and new kitchens are not. Where notice is needed you serve it at least two months ahead, so it goes out before the programme is fixed.
Does a locally listed building in Barnet need listed building consent for renovation?
No. Local listing is a council designation, not statutory listing. Hendon Church End Conservation Area, for example, has two locally listed buildings, the Chequers Public House and Church House. Local listing adds no consent regime of its own, but it is weighed when Barnet Council decides a planning application for external changes, and both buildings also sit inside a conservation area. Inside, the renovation proceeds under Building Regulations like any other building, so the status matters for windows, doors and roofs rather than rooms.
How can a Barnet homeowner check a house's planning status before renovating?
Start with the national Planning Data service, which returns 16 conservation area results for the London Borough of Barnet, including Railway Terraces, and see whether the address falls inside one. Then check the national list for statutory listing, and ask Barnet Council whether any further direction applies to the street. Doing this before the specification is written means windows, doors and roofing are chosen once, not changed after a refusal.
When does a Barnet refurbishment become a Building Regulations job?
Sooner than you might expect. Barnet's Finchley Garden Village guidance notes that approval is required for structural alterations, additions and, in some cases, refurbishment. In a renovation that can mean a new electrical circuit, new drainage, replacement windows, or re-rendering a large share of an external wall, which can bring in insulation requirements. Listing the notifiable items at the start lets inspections be booked in sequence rather than chased at the end.
