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.
In Carshalton, as anywhere in London, the price of a whole-house renovation is driven mainly by size, materials and access. Across London our guide sits at £58,000–£156,000 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

What are homes like around Carshalton?
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.
With that background in mind, here is how we typically handle a whole-house renovation for homes in Carshalton, from the first visit to the finished result.
Planning and building rules in Carshalton
Planning law differs across the UK. For a home in Carshalton, 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.
From survey to handover
Free site survey
A free survey comes first. It gives us what we need to price a whole-house renovation properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Price and scope agreed
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Getting ready
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a whole-house renovation are in place before the first day on site.
The work itself
Our trades complete a whole-house renovation while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
Why homeowners choose us
Frequently asked questions
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.
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.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
What contingency should I allow?
A contingency is money set aside for problems found once work starts, such as rotten joists, hidden damp or wiring that is worse than expected. For older houses, setting aside at least 10–15% of the build cost is sensible. We look for warning signs during the survey and price known issues upfront. If something unexpected is found, we explain it and price it before carrying on.
Can we live in the house while it is renovated?
Living in a house during a full renovation is possible but hard, especially while rewiring, plastering and the kitchen and bathroom are being done. Many people move out for the noisiest weeks or stay elsewhere for the whole project. If you stay, we can phase the work room by room and keep one bathroom and a basic kitchen working for as long as possible. We discuss this at the survey.
