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.
Getting a new bathroom right in Barnet starts with understanding the house you already have: its age, how it was built and what has been altered over the years. We survey first, then commit on paper to a price that holds as long as the scope stays the same. Across London, guide prices run at £6,500–£15,500 including VAT, and homes in East Barnet, Hadley Wood and Potters Bar are covered too.

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.
With that background in mind, here is how we typically handle a new bathroom for homes in Barnet, from the first visit to the finished result.
Do you need permission in Barnet?
Homes in Barnet come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
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.
How does the job run?
Free site survey
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new bathroom.
Written quote
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.
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 Barnet 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.
How we work
Common questions
How much does a new bathroom cost?
A typical family bathroom costs £6,500–£15,500 supplied and fitted, including tiling, a new suite, shower, lighting and an extractor fan. Shower rooms and simple en-suites cost a little less, while wet rooms, standalone baths and large-format tiles cost more. Moving the toilet or replacing rotten floorboards adds to the total. We confirm a fixed price for the agreed specification after the survey.
Do you cover East Barnet, Hadley Wood and Potters Bar?
Yes. As well as Barnet, we cover East Barnet, Hadley Wood and Potters Bar and the rest of London. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
What ventilation does a bathroom need?
A bathroom needs mechanical ventilation, usually an extractor fan, to remove steam and help prevent condensation and mould. Building regulations set minimum extraction rates for new or refitted bathrooms. A fan linked to the light with an overrun timer, or one with a humidity sensor, works well. Ducting should vent outside by the shortest practical route. We include a suitable fan in every bathroom quote.
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.
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.
Near Barnet
We survey and quote throughout Barnet's EN4, EN5, N3 and N12 postcodes and in surrounding places such as East Barnet, Hadley Wood and Potters Bar. The process and pricing approach are identical in each of them.
