GS Renovation refurbishes whole houses and flats across New Barnet, from its semis to Victorian terraces that have had a hundred years of piecemeal alteration and one bad 1980s modernisation. One team takes it back to sound fabric and rebuilds in the right order, from the structure and services through to plaster, joinery and decoration.
In New 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 New 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 New Barnet and bathroom renovation in New Barnet. With 50% of homes in New 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 a Victorian terrace in New Barnet
The order matters more than anything else in a full refurbishment. Structure first, then the roof and the rainwater goods, then first fix electrics and plumbing while the walls are open, then plaster, then second fix, kitchen, bathroom and decoration. Doing the pretty end early is how people finish a house twice. In a New Barnet terrace we usually start above head height, because a leaking valley gutter between two back additions has generally been the cause of the damp that everyone blamed on rising groundwater.
Damp in an EN4 terrace is rarely what the ad says it is. More often than not the ground outside has been raised above the internal floor by a patio or a path, the airbricks to the suspended floor are blocked or painted over, a cement render is trapping moisture in the brickwork, or the gutter is overflowing behind the downpipe. Fix those and the wall dries. We say that plainly rather than sell a chemical injection course, because a chemical course into a wall with an external ground problem does nothing at all.
Housing in New Barnet
The New Barnet and Hadley Wood statistical areas's housing, as the Council Tax list records it, is about 10,670 homes: 50% houses, 50% flats, with 17% pre-1919, 32% interwar and 52% built since 1945. Since many homes here are flats, refurbishing a flat in New Barnet starts with the freeholder's licence for alterations.
Renovating a post-war New Barnet house or a house to share
With 52% of New Barnet's homes built after 1945, a whole house renovation here often means post-war fabric rather than Victorian plaster. The finds are different. Textured ceiling coatings, thermoplastic floor tiles on bitumen adhesive, cement board around boilers and soffits can all contain asbestos in houses of that age. We ask for a refurbishment and demolition asbestos survey before strip-out, because it decides which rooms are stripped by a licensed contractor first and when the rest of the trades can start.
If the renovation is being done to let rooms to sharers, check Barnet's rules before the layout is drawn. The Planning Data record for Barnet's Article 4 direction on small houses in multiple occupation gives a start date of 2016-05-29. Where a direction like that applies, turning a family house into a small HMO needs planning permission rather than happening as of right. Confirm whether your New Barnet address is covered, because the answer changes how many bathrooms, kitchens and fire doors the renovation has to deliver.
Flats, leases and building control in EN4
A good number of New Barnet's Victorian and Edwardian houses were converted into flats, and refurbishing one is a different project from refurbishing a house. The lease sets what you may touch, the freeholder's licence to alter covers anything structural, and the managing agent will want method statements and the contractor's insurance before the first delivery. Most leases also restrict working hours, require a parking permit for the skip and forbid hard flooring over an occupied flat, which decides your floor finish long before you ever get to choose a colour.
Building control still applies either way. A whole house refurbishment in New Barnet typically triggers it several times over: any structural opening, the electrical work in kitchen and bathroom areas, a new or relocated boiler, insulation upgrades and any change to escape from the upper floors. We make a single application to Barnet Council or a registered building control approver, book the inspections around the programme rather than after the fact, and hand over the completion certificate at the end along with the electrical certificates and the engineer's drawings.

FAQ
Frequently Asked Questions about Home Renovation New Barnet
Can you quote home renovation for an EN5 property over the phone?
A rough steer on home renovation in New Barnet is possible by phone; a quotation is not. The steer is £40,000 to £150,000 or more (indicative), and the figure waits until the EN5 property has been seen, because post-war suburban construction rarely matches the assumption. The call also covers the approvals: building regulations sign-off for rewiring, drainage and structure. Ring 07472 424 226 or email info@gsrenovationltd.co.uk.
Should I strip the lath and plaster in my New Barnet terrace or overboard it?
Strip it where it has blown, overboard it where it is sound and you want the ceiling line kept. Tapping the ceiling tells you most of it: a hollow, drummy note means the plaster has lost its keys behind the laths and it will come down eventually, usually onto a new carpet. Stripping is filthy but lets you insulate and rewire properly. Overboarding with 12.5mm plasterboard and a skim is quicker and quieter, but it loses a little height and buries the problem if the laths are already going. Decide room by room.
Should the whole New Barnet house be rewired during a renovation?
If the floors are coming up anyway, usually yes. Old circuits, a board without modern protection and cable in poor condition cost far less to replace while walls are open than later. A rewire is notifiable under Part P, and the registered electrician we appoint certifies it. The cables are run at first fix, before plastering, so decide where sockets and lights go first.
Is it better to move out during a New Barnet renovation?
If the kitchen, bathroom and floors are all being done at once, yes. For stretches there will be no running water in some rooms, dust everywhere and no heating while pipes are changed. Moving out lets the trades work the whole house in the right order. If you stay, we phase the work so a bathroom and cooking space always remain.
What insulation goes in while a New Barnet house is opened up?
Wherever floors, roofs or walls are exposed. Loft insulation, insulation between suspended floor joists, and pipe lagging all go in while the house is open. Renovating a thermal element, such as replastering an external wall or replacing a roof, must bring it up to current standards. On solid walls, breathable materials are used so moisture does not get trapped.
Does a New Barnet renovation need party wall notices?
Only for work that touches the shared structure or digs near it. Pocketing a steel into the dividing wall, or stripping a breast off it, obliges you to warn next door two months or more before starting. An excavation deeper than their footings, within 3 metres of their house, carries a one month notice. Rewiring, replastering and a new kitchen need no notice at all.
Should cavity wall insulation be checked during a New Barnet renovation?
Yes, while the walls are open. A post-war cavity wall may have been filled after it was built, and on an exposed elevation poor fill or debris in the cavity can carry damp across to the inside face. In New Barnet 52% of homes were built after 1945. Where plaster is off, look for damp patterns on the inner leaf and ask for a borescope check of the fill before replastering seals it in.
What does renovating a New Barnet house built in 2000 or later usually involve?
Finishes and services rather than repairs to the fabric. Plasterboard fixed on adhesive dabs sounds hollow and is not a defect, and the walls may be timber frame, where fixings and cable routes follow the studs. In New Barnet 11% of homes were built in 2000 or later. If a new-home warranty is still running on a recent house, read its terms before structural changes are made.
Do New Barnet's housing figures describe every street?
No. The VOA figures for New Barnet cover New Barnet West, New Barnet Town & East Barnet and Hadley Wood together, so 50% flats is an average across all three. A road of interwar semis near Victoria Recreation Ground and a block of post-war flats sit in the same total. The survey of your own house decides the renovation scope, not the neighbourhood figure.
