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.
For a homeowner in Northolt, planning a new bathroom tends to begin with two questions: what will it cost, and how disruptive will it be? Our guide range is £6,500–£15,500 including VAT, and a typical job runs to 1–2 weeks per bathroom. Both numbers firm up once we have seen the property, measured up and agreed exactly what is included.

Local housing and a new bathroom
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.
That mix of housing shapes how we approach a new bathroom in Northolt: the age and construction of your home affect the materials, the method and, in the end, the price.
Permissions for a new bathroom in Northolt
As Northolt is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a 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
Free site survey
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.
Quote in writing
After the survey we send a quote for a new bathroom that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Getting ready
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
On site to finish
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.
Why homeowners choose us
Common questions
Can I move the toilet to a different position?
Moving a toilet is usually possible, but it is limited by the soil pipe, which needs a large-diameter pipe with a steady fall to the soil stack. Short moves along the same wall are often simple, while moving it across the room may mean lifting floors or boxing in pipework. A macerator pump is an option where gravity will not work. We check the stack position during the survey.
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.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
How long will a new bathroom take?
On a typical home, allow 1–2 weeks per bathroom. 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.
