Full refurbishments and whole-house renovations in Winchmore Hill. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes whole houses and whole flats across Winchmore Hill, taking substantial Edwardian properties back to the fabric and rebuilding them properly. One team runs the structure, the rewire, the plumbing, the plaster and the finishes to a single programme, so trades follow each other in the right order instead of queueing on the pavement.

Three things come up in nearly every Winchmore Hill house we strip out. Rewiring solid walls means chasing brick rather than dropping cables down a cavity, so the routes have to be planned with the plasterer before the electrician starts. The suspended ground floor is usually under-ventilated, with airbricks painted over or buried by a raised path, which we clear before anything is insulated. And the lath and plaster is a genuine decision: sound lath holds mouldings and takes the character with it if it goes, while blown lath that has lost its key is a false economy to patch.
The other recurring find is the legacy of an earlier conversion. Houses divided into flats decades ago tend to have services run wherever was easiest, waste pipes clipped across elevations, meters in cupboards under the stairs and fire doors that were never fire doors. Where a property is being brought back to a single family house we untangle all of that, and where a house is staying as flats we improve the separation between them properly, with sound and fire resistance to the floor between rather than a new carpet and hope.
The programme runs structure first, then first fix electrics and plumbing, then plaster, then joinery, kitchen and bathrooms, then second fix and decoration, with an Enfield building control inspection at each stage that will later be hidden. Electrical work is notifiable under Part P and is certified as part of the job. Where the layout changes and a wall comes out, the engineer we appoint designs the beam and building control signs it off. None of this needs planning permission because it is all inside the building.
Windows are the exception, and around Winchmore Hill Green they matter. Original timber sashes are one of the features the conservation area designation exists to protect, and if the property is a flat or listed the controls are tighter still. Repairing and draught proofing existing sashes, or replacing like for like in timber with slim double glazing, is normally the route that gets approved; plastic frames on a principal elevation are normally the route that does not. We check with Enfield planning first and build to what is actually consented.
A whole house refurbishment needs one party holding the programme, the sequence and the certificates together. We run structure, services and finishes with our own team, protect the cornices, sashes and lath worth keeping in a Winchmore Hill period house, and handle Enfield building control, the Part P certification and the engineer's involvement where walls move. Realistic dates, and an honest answer when something in the fabric changes them.

FAQ
Only a survey answers that honestly. Two Winchmore Hill houses of the same size can differ once home renovation is scoped, so we look at the N21 property first, then price the structure, the trades and the Enfield Council approvals as separate lines you can compare. That written quotation is what GS Renovation stands behind across Enfield and Edmonton. Nothing is owed for the N21 survey if you decide against going ahead with home renovation in Winchmore Hill. As a rough guide, home renovation in London ranges from roughly £40,000 to £150,000 or more for a full refurbishment (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Book the survey now and decide later, because that costs nothing. It gives GS Renovation the information to programme home renovation at your N21 home and gives you a real date rather than an estimate. Demand across Winchmore Hill and Enfield varies with the season. We will always tell a North London client honestly when the next slot genuinely is. The survey at N21 costs nothing and commits a Winchmore Hill homeowner in Enfield to nothing.
Yes. Full insurance is in place for home renovation at any N21 address, along with a five year guarantee on installations and Enfield Council building control coordinated by us. GS Renovation is a registered company, number 14611254, which a Winchmore Hill homeowner can verify in a minute. Email info@gsrenovationltd.co.uk and we will send the documents before you commit to anything in Enfield. Company number 14611254 appears on every Winchmore Hill quotation and on every Enfield invoice.
Yes. Listed building consent is required for works affecting character, inside as well as out, and it is separate from planning permission. Unauthorised work is a criminal offence. Where your Winchmore Hill property is listed we lead the application with Enfield Council before anything begins.
Almost all, which is exactly why the survey matters. Home renovation at an N21 address of that age is priced on what we find rather than on a standard detail, and GS Renovation has done enough of them across Winchmore Hill and Edmonton to know where to look. The 31 public MyBuilder reviews cover the same work. Ring 07472 424 226 for recent examples. Ask on 07472 424 226 what home renovation usually finds at an N21 address of that age.
It depends on where the house sits and what it is. Within the conservation area around Winchmore Hill Green, and for any flat or listed building anywhere, window replacement on the principal elevation is normally controlled and Enfield Council will expect timber sashes matching the originals in section, glazing bar pattern and opening method. Slim double glazed units in timber sashes are often acceptable; standard plastic replacements usually are not. Repair and draught proofing of sound original sashes is frequently the better answer anyway, since Edwardian joinery timber is generally better than anything you can buy now. We confirm the position with planning before ordering.
Across Enfield comfortably, and well into the surrounding North London. Home renovation at an N21 address is routine for us, and so is work in Edmonton and the streets between. GS Renovation will tell you honestly if travel makes a job impractical rather than pricing it defensively. Ring 07472 424 226 with the postcode for a straight answer. The Winchmore Hill survey is free whatever we decide. Small jobs and full projects are equally welcome in Enfield.
