London's housing stock throws up all sorts of challenges for a bathroom refit. A Victorian terrace in Clapham with original floorboards and lead pipework needs a very different approach to a 1960s conversion flat in Highbury with shared soil stacks, or a new-build in Nine Elms where everything's plasterboard and modern first-fix plumbing. Fitters working across the capital deal with tight stairwells, awkward parking for skips and vans, leasehold restrictions on when noisy work can happen, and party wall issues if you're knocking through or moving a stack. A good local fitter will know the quirks of your postcode, whether that's the clay soil movement affecting pipework in parts of south London or the Victorian conversions common around Tooting and Walthamstow.

The businesses featured here are drawn from public business listings and ranked using their review rating and the number of reviews they've collected, with a small lift given to those showing a working website and phone number. We then check each business's homepage to confirm bathroom fitting is genuinely what they do day to day, which keeps tilers, general builders and kitchen specialists who dabble occasionally off this particular list. Listings flagged as permanently closed get removed automatically, so you shouldn't find dead entries here. Where you see a Trust Verified badge, that business has gone through our fuller verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page sets out exactly what that involves. For any business without the badge, those checks haven't been done by us, and it's worth doing them yourself before you commit.

Before booking anyone, ask to see their public liability insurance certificate and check whether they're registered with a competent persons scheme if electrical or gas work is involved (moving a boiler or fitting an electric shower, for example). Ask for photos of recent jobs, ideally similar properties to yours, and get a written quote that breaks down labour, materials and any allowance for unexpected issues like rotten floor joists or old lead pipework needing replacement. It's worth getting two or three quotes rather than accepting the first one, since prices for a similar job can vary by a few thousand pounds across London depending on the fitter's overheads and how busy they are. Always confirm who's responsible for building control sign-off if you're moving the location of the bathroom or altering drainage, and get a rough timeline in writing so you know what to expect once the old suite is ripped out.
How We Select & Rate The Best Bathroom Fitters in London

Ranking is based on review rating and review count pulled from public business listings, with a small boost for businesses that show a working website and phone number. We check each business's homepage to confirm bathroom fitting work is what they primarily do, which filters out unrelated trades. Listings marked as permanently closed are removed automatically. Businesses carrying a Trust Verified badge have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for the complete list. Other businesses on this page haven't been independently verified by us, and appearing here isn't an endorsement. Do your own checks before hiring.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does a bathroom fitters cost in London?
A straightforward refit swapping like-for-like fittings in a small bathroom might run from around £3,500 to £6,000 including labour and basic materials. A full renovation with new pipework, tiling, an electric shower and moving fixtures around can push £8,000 to £15,000, and more in central postcodes like Kensington or Islington where fitters' overheads are higher. Costs climb further if you're changing the layout, dealing with old lead pipes, or need structural work for an en-suite. Get two or three written quotes so you can compare labour costs, tile allowances and what's included.
Do I need planning permission or building regulations approval for a bathroom refit in London?
Most straightforward bathroom refits don't need planning permission, but building regulations can apply if you're adding a new bathroom, altering drainage, or doing electrical work near water. If you're in a flat, check your lease for any restrictions on works and whether you need freeholder consent, particularly for anything affecting shared pipework or soil stacks.
How long does a typical bathroom installation take?
A basic refit with no layout changes usually takes five to seven working days. A full renovation involving new plumbing, electrics, tiling and plastering can take two to three weeks, longer if there are delays getting materials or if unexpected issues turn up once the old suite comes out, such as damp floor joists or outdated pipework that needs replacing.
Should I buy my own bathroom suite and tiles, or let the fitter supply everything?
Both approaches are common. Supplying your own fittings from somewhere like a bathroom showroom or online retailer can save money, but check sizes and tap connections match what the fitter's expecting. Letting the fitter supply everything is usually simpler and they'll often get trade discounts, though it's worth asking what markup is included in the quote.
What's the difference between a bathroom fitter and a plumber for this kind of work?
A plumber handles pipework and connections but might not do tiling, plastering or electrics. A dedicated bathroom fitter typically manages the whole job, plumbing, tiling, electrics for lighting and extractor fans, and coordinating any building work, either doing it all themselves or bringing in trusted subcontractors. For a full renovation, a fitter who manages the whole project usually saves you the hassle of coordinating several trades yourself.
How do I check a bathroom fitter is reliable before booking?
Ask to see their public liability insurance certificate and, if the job involves electrics or gas, check their registration with the relevant competent persons scheme. Look at recent customer reviews across a few different platforms rather than just one, ask for references from jobs done in the last year or so, and request photos of similar properties they've worked on. Get a written quote with a clear breakdown of costs and a rough timeline, and confirm who's liable for any damage during the works before you sign anything.
