A bathroom installation replaces your old suite with new sanitaryware, a bath or shower, tiling and fittings, including the plumbing, electrics, ventilation and waterproofing needed for a complete, watertight room.
Addresses across SW13, SW14, W3 and W4 fall within our coverage for a new bathroom, so if your home is in Chiswick we can arrange a survey on a day that works for you. We inspect the existing building, discuss materials and layout, and then price the agreed specification in writing. Expect a guide range of £6,500–£15,500 including VAT before that visit.

Building in Chiswick
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.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
In Chiswick, as elsewhere in London, we take the building's age and construction into account before recommending anything, because both can change what is involved in a new bathroom.
Permissions for a new bathroom in Chiswick
Which rules apply depends on where you live. For Chiswick, the answer is England, and the points below reflect that; we verify them with the council before quoting.
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
A visit to your home
A free survey comes first. It gives us what we need to price a new bathroom properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Your fixed price
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Booking the work
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 Chiswick property.
The work itself
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.
How we work
Common questions
Do I need a new boiler for a new shower?
You do not always need a new boiler for a new shower, but your hot water system decides what kind of shower will work well. Combi boilers suit mixer showers directly from the mains. Tank-fed systems may need a pump for good pressure, and electric showers heat their own water. We check your boiler, cylinder and water pressure during the survey and recommend a shower to match.
Will I have to go without a bathroom?
If it is your only bathroom, you will usually be without a shower or bath for most of the fitting time. We aim to keep the toilet working overnight wherever possible, refitting it temporarily at the end of each day during strip-out and first fix. If you have a second bathroom or downstairs toilet, the disruption is much easier. We plan the sequence with you before starting.
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 new bathroom, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Which postcodes in Chiswick do you cover?
We cover SW13, SW14, W3 and W4, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
How long does it take to fit a bathroom?
Fitting a typical bathroom takes one to two weeks on site. Strip-out and first-fix plumbing and electrics come first, followed by any plastering or boarding, waterproofing, tiling and then the suite, taps and fittings. Wet rooms and rooms with underfloor heating take longer because screeds and waterproofing need time to cure. We give you a day-by-day plan before work starts.
Nearby towns
We survey and quote throughout Chiswick's SW13, SW14, W3 and W4 postcodes and in surrounding places such as Acton, Barnes and Shepherds Bush. The process and pricing approach are identical in each of them.
