A whole-house renovation is a planned refurbishment of an entire home, typically combining rewiring, heating, plastering, new kitchen and bathroom, flooring and decoration, and sometimes layout changes, carried out in a logical order under one project.
Anyone planning a whole-house renovation in Isleworth wants three things: a clear price, a realistic timetable and a tidy job. We publish a guide of £58,000–£156,000 including VAT for London up front, explain that work normally takes 8–24 weeks on site, depending on scope, and confirm both in writing after a free survey of your property.

Homes in London
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
If your house in Isleworth fits one of these patterns, it helps us anticipate what a whole-house renovation will involve, though we always confirm the details on site.
Permissions for a whole-house renovation in Isleworth
Planning law differs across the UK. For a home in Isleworth, it is the England rules below that count, and we check them with the council ahead of any quote.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Survey and measure
First, someone visits your home in Isleworth to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Dates and permissions
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Isleworth property.
Finish and handover
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
What you can expect from us
Common questions
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a whole-house renovation, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
How long will a whole-house renovation take?
On a typical home, allow 8–24 weeks on site, depending on scope. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
In what order should renovation work be done?
A renovation should follow a set order so finished work is never damaged by later trades. It usually runs from roof and structural repairs, through strip-out, first-fix electrics and plumbing, then plastering, second-fix electrics and plumbing, kitchen and bathroom fitting, flooring and finally decoration. Windows are usually fitted before plastering. We plan the programme around this sequence so each trade follows on smoothly.
Which parts of a renovation need building regulations approval?
Several parts of a renovation fall under building regulations, including rewiring and new circuits, new boilers and heating systems, structural changes such as removing walls, replacement windows and changes to drainage. Some of this is self-certified by suitably registered trades, and some needs building control approval. In Scotland a building warrant may be needed for certain works. We arrange the right approvals and certificates.
How much does it cost to renovate a whole house?
A full refurbishment of a typical 3-bed house costs £58,000–£156,000, covering rewiring, heating, plastering, a new kitchen and bathroom, flooring and decoration. A light refresh costs much less, while renovations with structural changes cost more. The biggest variables are the condition of the house and the kitchen and bathroom specification. We survey every room and give you a written price for the agreed scope.
