Bathroom Fitters in London: The Complete 2026 Guide to Choosing the Right Installer
Finding a good bathroom fitter in London is harder than it should be. Search the term, and you'll mostly find company homepages telling you how great they are — not much that actually helps you tell a genuinely skilled fitter from someone who'll leave you with a leaking shower tray six months later.
This guide is different. It's written for homeowners who are about to hire someone, not for the fitters themselves. We'll cover what separates a reliable London bathroom fitter from a risky one, what you should expect to pay, the questions that actually reveal competence, and how to protect yourself if something goes wrong.

What Does a Bathroom Fitter Actually Do?
"Bathroom fitter" covers a wide range of setups in London, and understanding which one you're hiring matters more than most homeowners realise:
- Sole trader fitters — one experienced person who does everything themselves, often subcontracting an electrician or a Gas Safe engineer for specific jobs. Usually the most cost-effective option for a straightforward refit.
- Multi-trade companies — a business with plumbers, tilers, electricians and project managers under one roof. More expensive, but useful if your renovation involves structural changes or you want a single point of contact.
- Bathroom showroom install teams — fitters who work through a retailer, usually only installing products bought from that showroom.
None of these is inherently "better" — the right choice depends on the size and complexity of your job.
Qualifications & Checks That Actually Matter
Anyone can put "bathroom fitter" on a van. These are the checks that separate a properly qualified installer from someone learning on your bathroom:
- Gas Safe registration — legally required for anyone connecting or moving a combi boiler or gas-fed towel rail. Ask for their Gas Safe ID card and check the number on the Gas Safe Register directly — don't just take a photo of a card as proof.
- Part P registration (NICEIC or NAPIT) — required for any new electrical circuits, such as shaver sockets, extractor fans, or underfloor heating wiring.
- Public liability insurance — ask to see the certificate, not just be told it exists. £2 million cover is typical for domestic work.
- Waterproofing/tanking certification — particularly relevant for wet rooms, where poor tanking is the single most common cause of expensive leaks into the flat or room below.
- A trade body membership — such as the Federation of Master Builders or Checkatrade/TrustATrader vetting — isn't a guarantee of quality, but it does mean there's a formal route to raise a dispute.
London Bathroom Fitting Cost Guide (2026)
London labour costs run noticeably higher than the national average, and prices vary by borough. As a general guide:
| Job | Typical London Labour Cost |
|---|---|
| Like-for-like suite swap (same layout) | £1,800 – £3,500 |
| Full bathroom refit, layout unchanged | £4,000 – £7,500 |
| Full refit with layout changes / moved plumbing | £7,500 – £14,000+ |
| Wet room conversion | £5,000 – £11,000+ |
| Tiling only (per m²) | £45 – £90 |
Figures are labour-focused estimates and exclude materials — always get itemised quotes, since "materials included" pricing can hide markup on fittings.
7 Questions to Ask Before You Hire
- "Can I see photos of a job you completed at least a year ago?" — Recent photos show style. Older photos show whether the silicone, grout, and finish have actually held up.
- "Who does the tiling — you, or a subcontractor?" — Tiling is often the weakest link in an otherwise good fit. Know who's actually doing it.
- "What's your plan if you find an issue behind the old suite?" — In older London properties (Victorian/Edwardian conversions especially), rotten subfloors and old lead pipework are common. A good fitter has a clear answer, not a vague one.
- "Is the quote fixed, or could it change once work starts?" — Get any allowance for unexpected issues written into the quote up front.
- "What's your snagging process?" — Ask specifically how issues found after completion are handled, and within what timeframe.
- "Do you provide a written guarantee on workmanship?" — 12–24 months is standard for reputable fitters; anything verbal-only is a risk.
- "Can I supply my own fittings, or do I have to buy through you?" — Some companies only install what they sell you, often at a markup. A fitter who's happy to install fittings you've sourced yourself is usually more transparent on pricing.
Red Flags to Walk Away From
- Asking for full payment upfront, before any work starts.
- No fixed address, or a registered address that doesn't match where they say they're based.
- Reluctance to put the quote, scope, and guarantee in writing.
- Reviews that are all recent and generically worded, with no verified detail (a common sign of purchased reviews).
- Pressure to sign on the day of the quote with a "discount only available today."
- Vague answers about who is Gas Safe or Part P registered on the job.
Full Fit vs. Trade-Only vs. DIY
Not every job needs a full-service fitter:
- Full fit — best when plumbing, electrics, and layout are all changing. You want one team managing sequencing and liability.
- Trade-only (you project manage) — hiring a plumber, tiler, and electrician separately can save 15–25% on labour, but only works if you have the time to coordinate schedules and are confident spotting issues between trades.
- DIY with professional sign-off — some homeowners fit furniture and accessories themselves and bring in a Gas Safe engineer only for the boiler connection and a qualified electrician for the shaver socket. This is the most budget-friendly route for a cosmetic refresh, but isn't advisable for wet rooms or anything involving moved soil pipes.
Why Choosing Your Own Fittings Saves Money — and Gives You More Control
One of the most overlooked costs in a London bathroom renovation is the markup some fitters add when they supply the vanity units, tiles, and brassware themselves. Sourcing your own fittings — from a supplier with clear pricing and UK stock — typically means:
- You see the exact price you're paying, with no hidden margin folded into a "package" quote.
- You can choose styles and finishes on your own timeline, rather than from whatever a showroom stocks.
- Most experienced London fitters are used to installing fittings supplied by the homeowner and won't charge extra for it — if they do, that's worth asking about upfront.
At Bathroom Global, we supply vanity units, tiles, shower enclosures and mixers, and full bathroom suites with transparent, itemised pricing — ready for your chosen fitter to install, wherever you are in London.
FAQs
How much does it cost to hire a bathroom fitter in London?
Labour for a straightforward like-for-like bathroom swap typically runs £1,800–£3,500 in London, rising to £7,500+ for a full refit with layout changes. Always get at least two itemised quotes before committing.
Do I need a Gas Safe engineer for a bathroom renovation?
Only if the job involves connecting, moving, or removing anything on the gas supply — such as a combi boiler or a gas-fed towel rail. A general fitter cannot legally carry out this work themselves unless they are Gas Safe registered.
Can I supply my own bathroom fittings for the fitter to install?
Yes — most experienced London bathroom fitters are happy to install customer-supplied fittings, and doing so can significantly reduce the total cost of your renovation compared with a "package" quote that includes marked-up materials.
How long does a bathroom renovation take in London?
A like-for-like suite swap usually takes 3–5 working days. A full renovation with layout changes typically takes 2–4 weeks, depending on the scope and whether any structural or waterproofing work is involved.
Final Thought
The best London bathroom fitters aren't necessarily the ones with the biggest advertising budget — they're the ones who'll answer these questions clearly, put everything in writing, and let you choose your own fittings without pushing you toward theirs.
