GS Renovation refurbishes whole homes across Isleworth, from TW7's post-war flats and houses to its older Victorian and Edwardian terraces. One team manages the rewiring, replumbing, replastering and reconfiguring, so you deal with a single contractor rather than juggling trades. We bring dated homes back to life without losing their character.
In Isleworth, 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 Isleworth: 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 Isleworth and bathroom renovation in Isleworth. With 56% of homes in Isleworth flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Whole-house refurbishment in Isleworth period homes
A full refurbishment of an Isleworth terrace usually starts with stripping back to the brick and joists to reveal what decades of patching have hidden. Old rubber or fabric wiring gets replaced with a modern consumer unit, lead and iron pipework is swapped for copper and plastic, and lime or gypsum plaster is renewed throughout. We sequence the work so structural changes, first fix services and plastering happen in the right order.
Isleworth's Victorian and Edwardian homes carry features worth keeping: cornicing, ceiling roses, cast-iron fireplaces, panelled doors and original floorboards. Where these survive we restore them, and where they have been lost we can reinstate sympathetic replacements. Reconfiguring a dated layout, opening a through-lounge or relocating a bathroom off a cramped landing, sits alongside this restoration work. The result respects the age of the house while delivering the space and services a modern family needs.
Housing in Isleworth
The valuation list shows roughly 13,670 homes in Isleworth, of which 19% are pre-1919, 21% interwar and 61% post-1945, split 56% flats to 44% houses. Refurbishing a flat in Isleworth starts with the freeholder's licence for alterations, which matters here because most homes are flats.
Renovating the outside of an Isleworth house without an application stall
A whole-house renovation in Isleworth often reaches the outside: new windows, a front door, the roof covering, the front wall. Hounslow Council states that there are currently 29 conservation areas in the borough, and the Isleworth Riverside Conservation Area had its south western boundary extended on 13 July 1993. A house just inside that extension looks the same as one just outside it. Check the address first, because designation changes which external works can go ahead as permitted development and which need an application.
The local list is the second check. Hounslow's first local list was adopted in 1997 and was updated in September 2019. A house on it gains no separate consent regime for internal work, so the rewiring, the replastering and the new kitchen proceed as normal. The outside is where it counts, because the building's local interest is weighed in any application. Specify replacement windows and doors after both checks, and order them only once the route is settled, since joinery made to the wrong pattern cannot be returned.
One team managing your Isleworth renovation
The advantage of a single contractor on an Isleworth whole-house project is coordination. When the same team runs the structural steel, the electrics, the plumbing, the kitchen and the bathrooms, nothing falls between trades and the programme keeps moving. We plan the sequence so that messy first fix work finishes before decoration begins, and so building control inspections for notifiable electrical and structural work are booked at the right stages.
Living through a renovation is easier when the site is run tidily. In occupied Isleworth homes we dust-sheet routes, isolate work zones and keep the property secure and weathertight between visits. For larger projects many families choose to move out for the heaviest phases. Either way, you get one point of contact, a clear programme and regular updates, rather than chasing separate electricians, plumbers and plasterers across TW7.

FAQ
Frequently Asked Questions about Home Renovation Isleworth
Do you charge for a survey before quoting home renovation in Isleworth?
The survey for home renovation in Isleworth is free, and it is where the figure within £40,000 to £150,000 or more (indicative) is actually decided. At the TW7 address GS Renovation checks what decides the job: how much of the Isleworth property is stripped at once decides how the trades are phased. A written quotation follows; if you decide against it, nobody chases you. Ring 07472 424 226 whenever suits.
Can you renovate my Isleworth terrace while keeping its period features?
Absolutely. Preserving character is central to how we work in Isleworth. We carefully retain and restore cornicing, fireplaces, ceiling roses and original floorboards while renewing the wiring, plumbing, plaster and layout behind them. Where features have already been stripped out, we can source sympathetic replacements. You get a home that feels true to its Victorian or Edwardian roots but performs like a modern one.
Is asbestos likely in a post-war Isleworth home?
It is possible in anything built before 2000, and VOA data shows about six in ten Isleworth homes date from after 1945. Textured ceiling coatings, floor tiles, pipe boxing, bath panels and soffits are typical places to find it. A survey comes before strip-out, and any removal is programmed first, so no other trade disturbs it by accident halfway through the job.
What does the lease need to allow before renovating an Isleworth flat?
Read it before design, since several common changes need the freeholder's written consent: structural work, moving a kitchen or bathroom to a new position, and altering connections to the soil stack. Some leases also cover flooring and windows. The stack is normally shared with flats above and below, so moving a bathroom away from it is limited by more than consent. Early approval avoids redesign.
Which rooms should be done first in an Isleworth renovation we are living through?
Start with what serves every room. The rewire, consumer unit and heating pipework run through the whole home, so first fix happens everywhere before any room is finished. After that, bring the bathroom and kitchen back into use early so daily life works, then move on to bedrooms and living rooms. Decorating waits until every dusty trade has left.
Why does damp come back after renovating an older Isleworth house?
Usually because the cause stayed and only the plaster was replaced. Solid-wall houses near the river need their walls to breathe, and sealing them in cement render or gypsum can trap moisture. The fixes come first: lowering outside ground levels, clearing air bricks, repairing gutters, and extraction in the kitchen and bathroom under Part F. Only then is the wall replastered with a material that suits it.
Is converting the garage of an Isleworth semi a building notice job?
Usually. Semi-detached or detached houses are 13% of Isleworth homes, and where one has an attached garage, converting it adds a room without extending. Hounslow says a building notice is usually used for smaller projects, including converting a garage to a room. The inspector still sees the new floor insulation, the infilled door opening and the window. Read the original planning permission for the house first, because a condition can remove the right to convert the garage without an application.
Which Isleworth renovation work is better submitted as full plans?
Anything structural, extended or involving a change of use. 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. A renovation that combines a new bathroom with a knock-through and a rear extension belongs under one full plans application, so a single approved set of drawings covers the whole house and nothing waits on a later query.
Does Hounslow's building control charge for an Isleworth renovation include VAT?
Yes. Hounslow's building regulation charges scheme is effective from March 2026, and its charges are inclusive of VAT at the standard rate of 20%. The schedule figure is the amount paid. On a whole-house job, describe every notifiable element in the one application, the steel, the new bathroom and any extension, so the charge reflects the full scope from the start instead of being revised after the first inspection.
