Full refurbishments and whole-house renovations in Mill Hill. Trusted, professional, 30+ years' hands-on experience.
Mill Hill gives you two kinds of house to renovate: older village property around The Ridgeway with solid walls and lime plaster, and the interwar stock near the Broadway with cavity walls and long tired services. GS Renovation refurbishes both, running one programme from strip out to final decoration, backed by more than 30 years of hands on experience.

A full refurbishment is the moment to do everything you cannot reach again afterwards. We rewire, replace pipework and heating, replaster where old finishes have blown, and upgrade insulation while floors are up and walls are open. In the substantial detached houses here that is a longer programme than owners expect, simply because there is more of everything: more circuits, more radiators, more roof to insulate and often a consumer unit decades past replacement. We survey and set the order of work before anyone strips a wall.
The older village houses need a different hand. Solid brick walls in lime mortar behave differently from cavity walls, so wrapping them in the wrong insulation and sealing them behind gypsum and modern paint pushes moisture into the wall instead of letting it out. Where a house is breathable we keep it breathable, using lime plaster and finishes that suit it. The interwar houses nearer Mill Hill Broadway have the opposite problem: unfilled cavities and a loft carrying a token layer of flattened old mineral wool.
Order is what stops a renovation paying for the same work twice. Structural alterations come first, then first fix electrics and plumbing, then plastering, second fix, the kitchen, the bathrooms, and decoration last of all. Nothing gets finished before the messy work behind it is done. Electrical work and any structural change are notifiable, so Barnet Council's building control or an approved inspector signs those off and you get the paperwork on completion, rather than an awkward conversation with a buyer's solicitor about it in three years.
Consents inside a Mill Hill house are simpler than most people fear. Conservation area status controls the external appearance, so reconfiguring the rooms inside a Ridgeway house does not require conservation area consent. Listing is different, because in a listed building the interior is protected too, and taking out a chimney breast, a staircase or original joinery needs listed building consent first. We establish which category your house falls into at survey, since it changes both the programme and what is worth restoring rather than replacing.
One team, one sequence, one point of contact. We run the trades in an order that stops work being done twice, we keep an occupied house liveable wherever the scope allows it, and we are honest about which original features are worth restoring and which are past saving. More than 30 years of hands on experience in London's period and interwar housing sits behind that judgement.

FAQ
Not from us, though there are unknowns and we name them upfront. On an older Mill Hill property home renovation can uncover wiring, timber or drainage that nobody could see at the NW7 survey, and we tell you what we suspect before starting. Anything additional is priced and agreed in writing first. GS Renovation has never treated a surprise as a licence to inflate a Barnet invoice. Ring 07472 424 226 and GS Renovation will name the likely unknowns at your NW7 address. 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.
We will tell you exactly, once we have seen the house. Guessing a home renovation duration for a Mill Hill property without a survey helps nobody, and the NW7 visit is free. GS Renovation then issues a staged programme including the Barnet Council inspection dates and the drying time that cannot be rushed. That is the version to plan a Barnet household around. Ring 07472 424 226 and we will describe how a similar NW7 job ran in Barnet.
It is, and the paperwork proves it rather than the promise. Home renovation at your NW7 home is inspected by Barnet Council, certified at completion, and the installations carry a five year guarantee from GS Renovation. If something needs attention afterwards you call the same team that did the Mill Hill work. That is why so much Barnet work is repeat business. Ring 07472 424 226 whenever you need us. Repeat Barnet business is what the guarantee actually buys.
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 Mill Hill property is listed we lead the application with Barnet Council before anything begins.
It is our core work rather than a sideline. 1930s semi-detached and interwar suburban houses on generous plots dominate much of Barnet, and home renovation on them is what GS Renovation is on site doing most weeks. The 4.9 rating from 31 public MyBuilder reviews covers the same type of project. Ring 07472 424 226 and we will describe recent Mill Hill jobs at NW7. Mill Hill references for home renovation on properties of exactly that age and type all follow on info@gsrenovationltd.co.uk request too.
For internal work, usually not. Conservation area designation controls the outside of the building and the character of the area, so replacing windows, altering the elevations or demolishing boundary walls are the things that need attention from Barnet's planning team. Reconfiguring the rooms inside is a Building Regulations matter instead. The exception is a listed building, where the protection extends to the interior as well, so removing a fireplace, a staircase or original joinery needs listed building consent before any work starts.
We do, and the borough boundary is not something we price against. What decides whether GS Renovation takes a home renovation project is capacity and scope rather than whether the NW7 property is in Mill Hill or elsewhere in Barnet. Quotes are free and carry no obligation. Call 07472 424 226 for current availability. Aftercare visits reach a North London address just as easily. Nothing is owed for the NW7 survey or for the written quotation.
