A bathroom is the most plumbing-dense room in the house, and the one where a hidden mistake costs the most — a leak behind new tiles, or a shower that never quite works because it was matched to the wrong system. Whether you’re swapping a suite or planning a full refit, every plumber listed here is checked and verified before going live.

✅ Checked before listing — identity, insurance, trading presence, Gas Safe (where relevant). How we verify →
✅ Workmanship guarantee badges on listings — 1, 3, 6 or 12 months

Plumbers pay to be listed — no customer middleman fee, and enquiries go straight to the plumber. This covers the plumbing of a bathroom; tiling, electrics and any gas or boiler work are separate trades, quoted separately.

Planning a bathroom: the plumbing that makes or breaks it

A bathroom job is really several jobs at once — hot and cold supply to each fitting, waste from the basin, bath and shower, the soil connection from the WC, and often moving or adding pipework to suit a new layout. The plumbing is also the part that has to be right before anything is tiled or boxed in, because the expensive mistakes — a weeping joint, a waste that doesn’t fall correctly, a shower starved of pressure — only show up once they’re sealed behind a finished wall.

The single decision that most often goes wrong is the shower. What will work depends entirely on your hot-water system: a combi boiler gives mains-pressure hot water but only one draw at a time; a vented cylinder with a loft tank gives gravity pressure that often needs a pump to drive a decent shower; and an unvented (pressurised) cylinder gives strong mains-pressure flow to more than one outlet. Match the shower to the system and it’s excellent; mismatch it and no amount of fiddling fixes it. A thermostatic mixing valve is worth specifying too, to hold a safe, steady temperature. Electric showers sidestep the hot-water system entirely by heating cold water on demand, but the electrical side is a separate trade.

Layout is the other constraint. Waste and soil pipes rely on a fall, or gradient, to drain, so moving a bath or WC far from the existing stack isn’t always possible by gravity — which is where a macerator (a pumped WC and waste unit) comes in, common in Camden’s converted flats and basements where a bathroom sits a long way from the soil stack. A good plumber works through all of this first — system type, pressure, where the soil and waste can actually run, and how the job sequences with the tiler and electrician — before a single fitting is bought.

Hard Thames Water supply matters here too: scale builds up on showerheads, valves and cartridges, so it’s worth choosing fittings that are easy to descale and, in a refit, fitting isolation valves that make future maintenance a quick job.¹

Bathroom plumbing in Camden’s flats and period homes

In Camden the single biggest risk in a bathroom job is the flat below. The borough is mostly flats, with private renting the largest tenure per ONS Census 2021,⁷ so a bathroom usually sits directly above someone else’s ceiling. That makes proper waterproofing — tanking a wet area, sealing around the bath and shower tray, getting waste connections watertight — non-negotiable, and it means access to a shared soil stack, and often a managing agent’s consent for any layout change, are part of the job rather than an afterthought.

The borough’s older housing shapes what’s possible. Period homes across Hampstead, Bloomsbury and Camden Town often have solid floors and original layouts where moving a soil pipe is difficult, and listed-building or conservation rules can limit changes to layout or anything visible. Pressure varies too — upper-floor flats and homes at the top of Camden’s hills can have weaker supply pressure, which is exactly why the shower has to be matched to the system rather than chosen from a brochure. Where a bathroom sits far from the stack, a macerator is often the practical answer.

Responsibility follows the usual line: Thames Water looks after the mains and communication pipe to your boundary, while the internal pipework and fittings in your bathroom are yours.² If you rent, a bathroom problem goes to your landlord or agent — Thames Water’s general position is that the landlord is responsible for fixing leaks, though it can depend on the cause and your tenancy.³ In a Camden Council home, a bathroom repair goes through the council, on 020 7974 4444 out of hours.⁸

Water fittings, showers and the rules

A bathroom refit touches more of the water-fittings rules than most jobs, so it’s worth knowing where they bite. Under the Water Supply (Water Fittings) Regulations, several bathroom installations are “notifiable” — meaning Water Regs UK lists them as needing the water undertaker’s consent before work starts: a bath holding more than 230 litres, a bidet with an ascending spray or flexible hose, and a pump or booster drawing more than 12 litres a minute — which covers most power-shower pumps.⁵ In practice, a WaterSafe-approved plumber can carry out some notifiable work without giving advance notice, where their scheme scope allows, and issue a Certificate of Compliance on completion — though some work still needs notification or consent first.⁶

If you want strong, multi-outlet showers from an unvented (pressurised) cylinder, that cylinder is controlled work under Building Regulations (Approved Document G3): it must be installed by a suitably qualified competent person and either notified to building control or self-certified under a competent-person scheme.⁴ As for water efficiency, the Part G calculation that caps consumption applies to new dwellings, not a refit in an existing home — but any new fittings you install still have to comply with the Water Supply (Water Fittings) Regulations.⁴ And the one firm boundary: anything on the boiler or gas side of your hot water is Gas Safe work, not bathroom plumbing — see the Central Heating and boiler pages.⁹

Find a verified plumber for bathrooms by Camden district

Where you are in Camden shapes what a bathroom job involves.

Hampstead, Frognal & Dartmouth Park (NW3 / NW5 edge). Large period houses where moving a bath or WC means working around solid floors and awkward soil runs, and where listed-building rules can limit layout or visible changes.

Belsize Park, Swiss Cottage & South Hampstead (NW3 / NW6). Mansion-block and converted flats, where a bathroom sits above someone else’s ceiling — so waterproofing, soil-stack access and a managing agent’s sign-off are central to the job.

Camden Town, Chalk Farm & Primrose Hill (NW1). Flats above shops and rentals, where a bathroom over a commercial unit raises the stakes on leaks, and pressure on upper floors shapes which shower will actually work.

Kentish Town & Gospel Oak (NW5). Converted houses and council estates; bathrooms set far from the stack often run on a macerator, and on Camden Council homes a bathroom job routes through the council.

West Hampstead & Fortune Green (NW6). Rented period terraces and mansion blocks, where landlord or agent sign-off and hard-water-scaled showers are recurring themes.

King’s Cross, St Pancras, Somers Town & Euston (N1C / NW1 / WC1H). New-build flats with concealed cisterns, wall-hung WCs and pressure-reducing valves, where the existing system dictates what a new shower can do.

Bloomsbury, Holborn, Fitzrovia & Covent Garden (WC1 / WC2 / W1 edge). Listed buildings and flats over commercial premises, where layout changes need care — and where a call-out may fall inside the central London Congestion Charge zone.¹¹

What bathroom plumbing costs in Camden

Refits are usually a fixed project price; single swaps are smaller jobs. The ranges below are an editorial guide to sense-check a quote, not a fixed rate.

Editorial estimate only — these are not regulated rates, not market data and not a published cost survey. Prices vary widely by the suite, the layout, access, and whether pipework, tiling and electrics are included.

All of Camden sits inside the Ultra Low Emission Zone, so a plumber in a non-compliant vehicle pays £12.50 a day to work in the borough,¹⁰ which can feed into pricing. Central and southern Camden addresses — around Bloomsbury, Holborn, Covent Garden, Fitzrovia and some King’s Cross/Euston-edge streets — may also sit inside the central London Congestion Charge zone;¹¹ check a specific address by postcode with TfL.

Frequently asked questions

Why verified plumbers — not a general directory

A bathroom is a big-ticket job, and most of the plumbing ends up hidden behind tiles and panels — which is exactly why who does it matters. A leak sealed inside a wall, a shower matched to the wrong system, or a notifiable fitting installed without the right paperwork are expensive to put right, and harder to even see until the damage is done. Choosing from plumbers who are already checked takes that gamble out of it.

Every plumber here is checked before going live and re-verified annually: we confirm the business is legitimately trading and verify the named contact, we check evidence of public liability insurance, we review the feedback they’ve earned across the web, and we confirm they cover Camden’s NW, N, WC and edge-of-W postcodes before a profile is approved. For water-supply and fittings work you can also check a plumber yourself on WaterSafe, the free, water-industry-backed national register; and where a job touches gas or the boiler, we confirm registration directly with the Gas Safe Register.¹²⁹

Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →. And there’s no customer middleman fee: enquiries go directly to the plumber.
