A tap that drips, sticks or barely trickles is easy to put up with — but a single dripping tap can waste thousands of litres a year, and in hard-water Brent, scale is often behind it. This page lists checked, insured Brent plumbers who repair the tap or fit a new one, inside or out.

✅ 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

Tap jobs are usually a fixed price by the job, or an hourly rate plus parts — a worn washer or cartridge is a small repair, while a new or outside tap is a fit; ask which it is, and get the price, before work starts.

Tap faults — drips, stiffness and low flow

Most tap problems come down to one of a few worn parts, and which part depends on the type of tap.

Dripping from the spout. On traditional taps this is usually a worn rubber washer; on modern quarter-turn or lever taps it’s a worn ceramic disc or cartridge. It’s worth fixing rather than living with: WaterSafe warns that a dripping tap can waste up to 5,500 litres of water a year, which adds to the bill on a metered supply.¹

Leaking at the base or spindle. Usually worn O-rings or gland packing where the spout or handle meets the body — a service or new seals rather than a new tap.

Stiff or squeaky operation. Often a scaled-up or worn mechanism; a clean and re-grease or a new cartridge usually sorts it.

Weak flow from one tap. Commonly a blocked aerator (the screw-on nozzle at the spout tip) furred up with scale or debris, a partly closed isolation valve, or a scaled spout — frequently a clean or a cheap part rather than anything major. If every tap is weak, it’s a supply, stop-tap or pressure issue rather than the tap itself.

Taps come in several types — traditional pillar taps, kitchen and bath mixers, single-lever monobloc taps, quarter-turn ceramic-disc taps, pull-out spray kitchen taps, instant-boiling-water taps and outside bib taps — and the fix depends on which you have. A plumber will usually isolate the supply, identify the tap type, then check the aerator, the washer or cartridge, the O-rings, the flexible tails and the isolation valve before deciding whether a repair or a replacement makes sense. Matching the part to the tap’s make is half the job, so before booking it helps to send a photo of the tap, its make and model if you can see them, whether it’s dripping, stiff, leaking or low-flow, and whether the isolation valve under the sink works.

Brent homes: hard water, outside taps and who’s responsible

A few Brent specifics make taps a more frequent job here than you’d think.

Hard water is a common contributor. Thames Water classes all the water in its region as hard, and that scale builds up on washers, ceramic discs, aerators and spouts — a common reason a Brent tap starts dripping, stiffening or losing flow as it ages.² And because that drip shows on a metered bill — whether you’re supplied by Affinity Water in the north or Thames Water in the south, as set out in Brent’s planning guidance — there’s a direct cost to leaving it.³

An outside tap needs more than plumbing it in. Fitting a garden tap brings in a water-safety rule: an outside tap must have backflow protection so that contaminated water — for example from a hose left in a pond, bucket or watering can — can’t be drawn back into your drinking water. As WaterSafe explains, for an ordinary domestic garden tap that protection is a double check valve, fitted in the right place under the Water Supply (Water Fittings) Regulations; higher-risk or commercial uses can need more.⁴ A proper installer fits the right device, with an internal isolation valve and frost protection (usually inside, away from the cold), as part of the job — worth checking it’s all included in any quote.

In flats, monobloc mixers and concealed isolation valves are common, and reaching the right isolation valve, riser shut-off or stopcock can be part of the work — sometimes via the managing agent. In Kilburn and Brondesbury conversions, a leak under a basin often traces back to old flexible tails or an isolation valve boxed into a later vanity unit.

If you rent, working taps are the landlord’s responsibility. Under section 11 of the Landlord and Tenant Act 1985, a landlord on a short tenancy must keep the installations for the supply of water — which include the taps — in repair and proper working order.⁵ Brent council tenants should report a faulty tap to Brent Council / Brent Housing Management on 020 8937 2400.⁶

Find a verified tap-repair plumber by district

Where you are in Brent shapes the taps you’re likely dealing with.

Wembley, Wembley Park & Tokyngton (HA0, HA9) — Flats with monobloc mixers and concealed isolation valves, where reaching the right valve is part of the job and access can run through the managing agent.

Alperton (HA0) — Newer apartments with modern lever and ceramic-disc taps, and instant-boiling-water taps in some kitchens that need a specialist for the unit.

Willesden, Harlesden, Church End & Stonebridge (NW10, NW2) — Terraces and flats with a mix of older washer taps and modern replacements, plus kitchen mixers and awkward isolation in flats above shops.

Kilburn, South Kilburn, Queen’s Park & Brondesbury (NW6, NW10) — Victorian terraces, commonly with original pillar taps being upgraded to mixers, and mechanisms heavily scaled by hard water.

Kensal Green & Kensal Rise (NW10, NW6) — Period homes where dated basin and bath taps are commonly repaired or swapped.

Cricklewood, Dollis Hill & Mapesbury (NW2) — Larger older houses near the Barnet and Camden boundary, with kitchen, bathroom and garden taps all in regular use.

Kingsbury, Queensbury, Kenton & Northwick Park (NW9, HA3) — Interwar suburban houses with gardens, where outside taps — and their backflow protection and frost protection — come up alongside busy family kitchens.

Sudbury, Preston & North Wembley (HA0, HA9) — Suburban houses with gardens and utility areas, where outside and utility taps, and older stop taps, are a frequent request.

Park Royal, Twyford & Brent Park (NW10 and edges) — Commercial premises with high-use washroom and kitchen taps, where higher-risk use can need a higher level of backflow protection. See Commercial Plumbing in Brent.

What it costs

Most tap work is priced by the job or by the hour plus parts; a new tap unit is an additional cost. The figures below are indicative ranges to sense-check a quote, not fixed prices.

Editorial estimate only — these are not regulated rates, not market data and not a published cost survey. Agree whether the tap is repaired or replaced, whether the tap unit is included, and whether an outside tap’s check valve is part of the price, 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;⁷ but Brent sits outside the central London Congestion Charge zone, so that charge doesn’t apply to ordinary Brent callouts.⁸ 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 tap is a small job, which is exactly why it’s easy to be charged for a full replacement when a relatively cheap cartridge would have done — or to have an outside tap fitted without the backflow protection the regulations require. The value of a verified listing is a plumber who repairs the part where that’s right and fits a new tap properly where it isn’t.

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 taps and their fittings are 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 — the same regulations that govern backflow protection on an outside tap.⁹ Where a job forms part of a wider project that also touches a gas appliance, we confirm Gas Safe registration directly with the Gas Safe Register.¹⁰

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 →.

A dripping or stiff tap is one of the smallest jobs in the house and one of the easiest to overpay for — most of the time it’s a washer, a cartridge or a scaled aerator. This page exists so the plumber who fixes it, or fits a new one to the regulations, is one who’s already been checked.
