What this covers: a single tap — a dripping or leaking tap, a stiff or seized one, weak flow from a tap, or fitting a new one (basin, bath, kitchen mixer, or an outside tap). The sections below cover why taps fail here and what a repair or replacement involves.
Routing: a tap as part of a bathroom or kitchen refit belongs with that job; a hidden leak with no obvious source is leak detection, not a tap repair.
Costs: from a washer or cartridge to a new tap fit. See What it costs below.

Why taps fail in Newham
Most tap problems here trace back to one thing: hard water.
Thames Water classes all its supplies as hard, and over time the dissolved minerals leave limescale on the parts inside a tap.1 Scale builds up on the ceramic disc cartridge or the washer that seals the tap, so it no longer closes cleanly — and the tap drips. The same scale furs up the aerator at the spout, which is why a tap can slowly lose flow or spray unevenly. A drip is worth fixing promptly: on a metered supply it adds to the bill, and a constant trickle can stain a basin and wear the seat further.
So a tap that’s dripping usually needs a new washer or cartridge; a tap that’s lost flow often just needs the aerator unscrewed and descaled or replaced. A good plumber will tell you which, rather than replacing a whole tap that only needs a part.
Repair or replace
Whether a tap is worth repairing or replacing comes down to its type and age.
Worth repairing: a quality tap that’s dripping or stiff — a new washer (on older taps) or a new ceramic cartridge (on modern quarter-turn and mixer taps) usually fixes it for a fraction of a replacement, and the part is tap-specific so it helps to know the make.
Worth replacing: a cheap or badly corroded tap, one where the body is scaled or pitted, or where you want to change style — a basin mixer for a pair of taps, say. Replacement also means the plumber can fit isolation valves on the supply if there aren’t any, so the next repair doesn’t mean draining the system.
Either way, the supply needs isolating first — and that’s more of a question in a flat than a house. Newham is a flat-heavy borough: the Office for National Statistics records flats rising to 54.6% of dwellings by 2021, the largest increase of any local authority in England.2 In a flat the isolation may be a valve serving just your home, so it’s worth knowing where yours is before the work — the find your stop tap guide explains how. And while the tap and the pipework inside the flat are normally the resident’s responsibility, Newham Council notes that a building’s structure and communal parts are the council’s or freeholder’s — so a shared riser or a stop valve outside the flat may need the managing agent or landlord involved.3

Tap work is much the same across the borough — the main difference is the age of the fittings.
East Ham, Forest Gate, Manor Park and Plaistow (E6 / E7 / E12 / E13). Newham’s own Character Study groups Manor Park, East Ham, Forest Gate, Green Street, West Ham and Plaistow as the borough’s northern character area and identifies Victorian and Edwardian housing as a defining built type there.5 Older housing tends to mean older fittings — traditional washer taps, the chance of a scaled or seized valve, and sometimes no local isolation valve on the supply — so on any tap job it’s worth a plumber checking what’s there before quoting a straight swap.
Stratford, Stratford City, East Village, Canning Town and the Royal Docks (E15 / E16 / E20). This side of Newham is better treated as a flats-and-managed-buildings area than a house-street tap job. Newham’s Characterisation Study describes the Royal Docks as rapidly changing from industrial to high-density residential, with contemporary development including flats of four to six storeys, towers of around twenty storeys, and twelve-storey blocks around Barrier Park.7 Canning Town adds to that: the council describes a £3.7 billion regeneration of 10,000 new homes, 3,500 completed or on site.8 For tap work, the practical point isn’t the tap type — it’s not assuming a simple house stop tap: in a flat or managed block, check where the flat’s own isolation valve is, whether building access is needed, and whether a problem sits inside the home or in shared building services.
What it costs
Tap work is usually a quick, fixed-price job. The figures below are a general guide for London, not a quote.
| Job type | Indicative range (London) |
|---|---|
| Replace a washer or cartridge | £70–£150 |
| Descale or replace an aerator | £60–£100 |
| Fit isolation valves | £80–£160 |
| Supply and fit a new tap | £100–£250 |
| Fit an outside tap | £120–£250 |
Editorial estimate only. These figures are an indicative guide to help you plan — they are not regulated rates, not market data, and not a published cost survey. A small job often has a minimum call-out charge, so it can be worth grouping a few tap jobs into one visit. For reading a quote, see how to read a plumbing quote and the London plumbing costs guide.
Newham is within the London-wide Ultra Low Emission Zone, which Transport for London operates 24 hours a day across every London borough, with a daily charge for vehicles that don’t meet its emissions standards.4 A plumber using a non-compliant vehicle may factor that into their pricing, so it’s reasonable to ask.
Frequently asked questions
Usually a worn washer or a scaled ceramic cartridge — the seal no longer closes cleanly.
In hard-water Newham, scale is the most common culprit.
A new washer or cartridge fixes it, and you don’t need a whole new tap.
Often not.
It’s frequently just the aerator at the end of the spout furred up with limescale.
Unscrewing and descaling or replacing it usually restores the flow.
A good-quality tap is usually worth repairing — a washer or cartridge is cheap.
A corroded, scaled or cheap tap is often better replaced.
That also lets the plumber add isolation valves for next time.
A like-for-like swap is doable if you can isolate the supply and the connections are accessible.
Corroded or awkward pipework, or no isolation valve, is where it’s worth a plumber.
Know where your stop tap or isolation valve is first.
On a metered supply it adds to the bill.
A constant drip also wears the tap seat and can stain the basin.
So a small fix now saves a bigger one later.
Yes, many plumbers do — it’s a tee off the cold supply with its own isolation valve and the backflow protection required under the Water Supply (Water Fittings) Regulations.
WaterSafe notes those regulations specify that an outside tap should always have a double check valve to stop water siphoning back into the mains, so for ordinary garden-hose use that’s what a compliant fit includes.
If the property is in one of Newham’s conservation areas, a new outside tap that means a visible penetration through an external wall is worth checking first; the tap itself is unaffected.

Most tap problems here come down to scale — and a drip is worth fixing before it adds up. In hard-water Newham a dripping or weak tap is most often a worn washer, a scaled cartridge or a furred aerator, and the fix is usually a part rather than a whole new tap. Know where your stop tap or isolation valve is, decide whether the tap’s worth keeping, and a verified Newham plumber from the list above can sort it.
