GS Renovation carries out whole-house refurbishments throughout Brentford, from riverside and post-war flats to the period terraces and interwar semis of TW8. We bring one accountable team to rewiring, replumbing, replastering and reconfiguring dated layouts, sequencing every trade so your Brentford home is renovated without the chaos of managing separate contractors.
In Brentford, 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 Brentford: 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 Brentford and bathroom renovation in Brentford. With 65% of homes in Brentford flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Refurbishing Brentford's converted apartments
Most Brentford homes are flats, many of them new-build riverside apartments, with post-war blocks and a few warehouse conversions besides, and refurbishing one brings its own considerations. Structural change is limited by the leasehold and by the building's shared frame, so much of our work is about reconfiguring within the existing footprint, upgrading services and improving finishes. We rewire, replumb and replaster, then rebuild kitchens and bathrooms to a modern standard while respecting the sound-insulation expected between flats.
Working in an apartment block means coordinating with the managing agent from the outset. We agree working hours, protect communal corridors and lifts, and follow building-management rules so a refurbishment in TW8 never becomes a dispute with the freeholder or neighbours. Notifiable electrical work is certified by a registered electrician under Part P, and everything is finished cleanly so you can move back into a home that feels genuinely renewed.
Housing in Brentford
Brentford has around 13,230 homes on the Council Tax list: 61% post-war, 24% interwar and 15% predate 1919, with 65% flats and 35% houses. Where most homes are flats, refurbishing a flat in Brentford starts with the freeholder's licence for alterations.
Renovating Brentford houses: garages, designations and the local list
Semi-detached and detached houses make up 16% of Brentford's homes, and where one has an attached garage, converting it adds a room without building out. Hounslow says a building notice is usually used for smaller projects, and converting a garage to a room is one of its examples. The work is still inspected: a new floor insulated and raised to meet the house, the door opening filled with a wall that meets current thermal standards, and a window for light and, where the layout needs it, escape. Read the original planning permission for the house first, because a condition can remove the right to convert a garage without an application.
Outside the house, designation shapes a renovation more than the interior does. Hounslow Council states that there are currently 29 conservation areas in the borough, and its local list, first adopted in 1997, was updated in September 2019. Before a whole-house renovation that includes windows, doors, the front boundary or the roof covering, check the Brentford address against both. In a conservation area, side extensions, two storey rear extensions and some roof and cladding work lose their permitted development rights, and an Article 4 direction can remove more. A house on the local list keeps its rights, but its local interest is weighed in any application. A renovation specified on the wrong assumption stalls with the scaffold already up.
Whole-house projects in Brentford terraces
Where Brentford has period terraces, a full renovation is often the chance to put right decades of piecemeal alteration. We strip back to sound structure, upgrade the wiring and plumbing to current standards, and reconfigure layouts that no longer suit modern living. Where original features such as cornicing, fireplaces or panelling survive, we restore them sympathetically rather than stripping the character out of the house.
The value of one team is in the sequencing. Structural work comes first, then first-fix services, plastering, kitchens, bathrooms and finally decoration, each trade following on cleanly from the last. Any load-bearing changes are built to the engineer's design and signed off by building control, and notifiable electrics are certified by a registered electrician under Part P. The result is a Brentford home that works from top to bottom, delivered on a single programme with one point of contact.

FAQ
Frequently Asked Questions about Home Renovation Brentford
How does your home renovation price in Brentford compare with a national firm's?
A GS Renovation price for home renovation in Brentford compares well with a national firm's because there is no head office to fund, and both should sit within £40,000 to £150,000 or more (indicative). GS Renovation is the contractor doing the work at TW8, not a broker adding a margin. Compare the scope, including Part P notification for the rewire and Hounslow Council building control sign-off, not just the total.
How much can I change when renovating a Brentford conversion flat?
Internal renovations such as rewiring, replumbing, replastering and new kitchens or bathrooms do not need planning permission, and we handle them routinely. Structural change is more limited in a leasehold conversion, so any load-bearing alteration needs the freeholder's licence, an engineer's design and building control sign-off. We advise early on what is realistic within your building's rules and shared structure. A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Hounslow Council, and doing it without consent is a criminal offence.
In what order do the trades work through a Brentford flat refurbishment?
Strip-out first, then first fix: cables, back boxes, pipework and any new waste runs go in while walls and floors are open. Plastering follows, and only then second fix, when sockets, radiators, sanitaryware and the kitchen go on. In a TW8 block the noisy strip-out days are booked with the managing agent, since block rules usually limit drilling hours. Reversing any step means cutting into new plaster.
Can I stay in my Brentford flat during a full renovation?
It is harder in a flat than a house, because there is no upstairs to retreat to. Water and power go off during parts of first fix, and the only bathroom may be out of use for a stretch. A pattern that works is moving out from strip-out to plastering, then returning once one bathroom and a basic kitchen point are running while second fix continues around you.
Does rewiring a Brentford flat have to be notified?
Yes. A full rewire adds new circuits, which makes it notifiable under Part P, and a registered electrician carries it out and issues the certificate. Keep that certificate with the building control record, because managing agents and buyers' solicitors ask for both. The consumer unit position is agreed first of all, since moving it changes every cable route through the flat.
Should the kitchen or the bathroom be renovated first in a Brentford home?
In a two-storey house where the bathroom sits over the kitchen, do the bathroom first, so its new waste is tested for leaks before a fresh ceiling and units go in underneath. In a single-level flat both rooms drain to the same soil stack, so the deciding factor is which connection needs altering, and that pipe route is settled once for both rooms rather than twice.
Which parts of a Brentford renovation need full plans rather than a building notice?
Hounslow's building control service says a full plans application is usually used for major projects such as new buildings, extensions or alterations, or a change of building use, while a building notice suits smaller jobs such as a new bathroom. A whole-house renovation can contain both kinds of work. Where it includes an extension or a structural alteration, running everything under full plans means one approved set of drawings covers the job, and nothing is left for a later query.
How far ahead should a Brentford renovation book its building control inspections?
At least 1 working day ahead, which is Hounslow's minimum notice for an inspection request. On a whole-house job that becomes a rhythm: drainage before backfilling, steel before boxing in, insulation before boarding. Each visit is a hold point for the next trade, so the programme shows the inspection and the following trade the day after it. The final visit comes last, and Hounslow issues a certificate of completion once the work is completed and inspected.
What should the owner of a newer Brentford home check before a full renovation?
The warranty and the handover pack. 34% of Brentford homes were built in 2000 or later, and a home that recent may still be inside a new home warranty, which can exclude elements altered by later work. The handover pack should also hold the electrical certificates, the ventilation commissioning sheet and the drainage layout. Read the warranty terms before stripping out, and keep every new certificate with the originals so the file stays complete for a sale.
