A new bathroom is one of the bigger plumbing jobs a home gets — and the one where the wrong shower on the wrong system, or a waste that won’t fall, only shows up once the tiles are on. This page lists checked, insured Brent plumbers who plan, install and replace bathrooms so it works the first time.

✅ 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

A bathroom install is usually a fixed price per project, sometimes a day rate for smaller works — get a clear scope of what’s included (suite, shower, tiling, waste, making good) and whether it’s a like-for-like swap or a new layout, before work starts.

Planning a bathroom — and the shower question

A bathroom job runs from swapping a tired suite to a full re-fit or a wet room. The work usually splits into first fix — pipework and waste roughed in — and second fix, where the suite, taps and shower go on, followed by tiling and making good. The decisions that cause regret are mostly made before any of that.

The shower question comes first. What shower will actually work depends on your water system. A gravity-fed system — a cold tank in the loft feeding a hot cylinder — gives low pressure and often needs a pump to drive a decent shower. A combi boiler or an unvented (mains-pressure) cylinder gives good pressure already, but you must not fit a standard shower pump to a combi or mains supply. An electric shower heats its own water straight from the cold mains, so it suits most systems, including low-pressure ones. A good plumber checks the system’s pressure, flow rate, hot-water capacity and pipe sizes, and confirms the chosen shower is compatible, before any materials are bought — getting this right is how you avoid a trickle.

The connections and the rules. A bath, basin or shower needs the right trap and a waste that falls correctly to the soil stack. As WaterSafe sets out, the supply connections fall under the Water Fittings Regulations while the waste pipework comes under Building Regulations.¹ There’s also a scald rule: in a new home — or a new dwelling created by a change of use, such as a conversion — Building Regulations (Approved Document G) require the hot water delivered to a bath to be limited to 48°C, normally with a thermostatic mixing valve; for a bathroom replaced in an existing home it isn’t mandatory, but it’s recommended, particularly where the very young or very old use it.²

Like-for-like or a new layout? Swapping a suite for a similar one in the same place is straightforward. A new bathroom, or one in a new location, can bring in Building Control for drainage and ventilation — a new bathroom needs adequate extraction — and any electrical work in the bathroom must be carried out to the right standard by a qualified person. Two things worth insisting on at this stage: concealed shower valves, wall-hung frames and concealed cisterns should be left with service access, or a small future repair means opening a tiled wall; and a wet room is more than a tiled floor — it needs the wet zone tanked on floor and walls, correct falls to the drain and careful detailing around corners and pipe penetrations, because silicone alone is not waterproofing.

Brent homes: hard water, flats and older systems

Brent’s water and housing shape the bathroom decisions here.

Hard water is hard on showers. Thames Water classes all the water in its region as hard,³ and Brent’s own planning guidance confirms the borough is supplied by Affinity Water in the north and Thames Water in the south — both hard-water suppliers.⁴ That scale builds up on showerheads, thermostatic shower cartridges, mixer valves and any thermostatic mixing valve, so in Brent a shower’s performance and a valve’s life depend on choosing good fittings and keeping scale down.

Flats decide the shower for you, and raise the stakes on leaks. Many flat installations need checking for a combi or unvented mains-pressure system before a shower is chosen, because a pump isn’t the answer and mustn’t be fitted to a combi. The waste connects to a communal stack, and a bathroom leak — a failed seal, a waste that lets go, or poor wet-room tanking — is a classic cause of a flood that reaches the home below; the Association of British Insurers notes water damage (“escape of water”) is one of the most common buildings-insurance claims, which is why the waterproofing and waste connections are worth getting right.⁵ In a Wembley Park or South Kilburn flat, the layout can be limited by the existing soil stack and riser access, and a shut-off may have to be booked through the managing agent. Where a bathroom is added below the natural fall to the soil stack, in some conversions and basements, a macerator pump is used.

Older terraces often mean low pressure. The Victorian and Edwardian stock around Kilburn, Willesden and Kensal can still be on a gravity-fed system, where the realistic options for a good shower are a pump (on gravity) or an electric shower — a decision to settle before buying anything. In a Kilburn or Willesden conversion, moving a bath or shower across the room can also fail if the waste can’t keep enough fall back to the stack, so the layout has to follow the drainage, not just the design.

If you rent, baths and basins are among the sanitary fittings a landlord must keep in repair under section 11 of the Landlord and Tenant Act 1985.⁶ Brent council tenants should report a problem to Brent Council / Brent Housing Management on 020 8937 2400.⁷

Find a verified bathroom plumber by district

The right bathroom approach varies across the borough.

Wembley, Wembley Park & Tokyngton (HA0, HA9) — Flats often on combi or mains-pressure systems (so no pump), with waste to communal stacks, a real leak risk to the flat below, and access through the managing agent.

Alperton (HA0) — Newer apartments, often on unvented mains-pressure systems, where wet rooms and concealed fittings often feature.

Willesden, Harlesden, Church End & Stonebridge (NW10, NW2) — Terraces and flats with a mix of gravity-fed and combi systems, and plenty of dated suites being replaced.

Kilburn, South Kilburn, Queen’s Park & Brondesbury (NW6, NW10) — Victorian terraces that can still be on gravity-fed, low-pressure systems — the pump-or-electric-shower decision — and conversions adding bathrooms.

Kensal Green & Kensal Rise (NW10, NW6) — Period homes where full re-fits of old bathrooms are the typical job.

Cricklewood, Dollis Hill & Mapesbury (NW2) — Larger older houses near the Barnet and Camden boundary, with family bathrooms and en-suites.

Kingsbury, Queensbury, Kenton & Northwick Park (NW9, HA3) — Interwar suburban houses with family bathrooms, en-suites added in lofts or extensions with long waste runs back to the stack, and hard-water scaling on showers.

Sudbury, Preston & North Wembley (HA0, HA9) — Suburban houses with second bathrooms, en-suites, and wet rooms fitted for accessibility.

Park Royal, Twyford & Brent Park (NW10 and edges) — Commercial premises with staff washrooms and facilities. See Commercial Plumbing in Brent.

What it costs

A like-for-like suite swap is a different job from a full re-fit or a wet room. The figures below are indicative ranges for labour to sense-check a quote, not fixed prices — tiling, materials and electrical work are usually separate.

Editorial estimate only — these are not regulated rates, not market data and not a published cost survey. Agree the scope, what’s included, and what’s billed separately (tiling, materials, electrics), before work starts.

Two Brent points on rates: the borough is inside London’s Ultra Low Emission Zone, which operates across all London boroughs every day except Christmas Day, so a non-compliant van may carry a daily ULEZ charge;⁸ but Brent sits outside the central London Congestion Charge zone, so that charge doesn’t apply to ordinary Brent callouts.⁹ For help reading a quote, see How to Read a Plumbing Quote and the London Plumbing Costs & Compliance Guide.

Frequently asked questions

Why verified plumbers — not a general directory

A bathroom is a job you live with for years, and the expensive mistakes are the hidden ones — the wrong shower for the system, a waste that doesn’t fall, a leak behind new tiles. The value of a verified listing is a plumber who specs the right system before anything is bought and connects it to the regulations.

Every listing is checked before it goes 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 look at the plumber’s track record across the web, and we confirm they cover Brent’s postcodes before a profile is approved. Because bathroom work is water-fittings work, you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register of approved plumbers trained in the Water Fittings Regulations.¹⁰ Where the work touches the boiler or heating, we confirm Gas Safe registration directly with the Gas Safe Register.¹¹

Ranking here isn’t for sale: profiles aren’t ordered by who pays, and there’s no per-enquiry middleman fee — your enquiry goes directly to the plumber. A single top slot may be a paid sponsored position, and where it is, it’s clearly labelled “Sponsored.” Profiles can be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →.
