What’s wrong with it

Tap faults are mercifully short-listed:

It drips from the spout. Traditional taps: a worn washer or a damaged seat — the washer is minutes, and a scored seat can be re-ground with a reseating tool rather than replacing the tap. Modern monobloc and lever taps: the ceramic-disc cartridge has worn or scaled — a straight swap if the cartridge can be identified and sourced, which is exactly the kind of small knowledge a good plumber carries.

It leaks from the base or under the handle. O-rings and gland seals — small parts, quick fixes — or, on a kitchen mixer, the body seals where the spout swivels. Water tracking down under the sink also loosens the tap over time; worth fixing before the worktop or unit swells. In Richmond or Twickenham flats, treat this one with urgency: a basin or kitchen tap leak can be tracking into the ceiling below long before the tap itself looks serious — isolate first, then book.

The handle is stiff, or the tap has seized. In this borough, that’s usually scale on the headgear or cartridge (see below) — forced handles snap spindles and crack ceramic discs, so service it rather than strong-arm it.

Flow has dropped or sprays oddly. Nine times out of ten the aerator at the spout tip has scaled up — unscrew, descale or replace. If flow is poor at several outlets, the question moves upstream: a partly closed valve, a scaled supply run or a pressure issue worth a General Plumbing look.

The isolation valve underneath doesn’t work. The unsung fault: when the tap finally needs work, the little valve below it has seized open, and a five-minute cartridge swap becomes a whole-house shut-down. Before any tap repair is quoted, it’s worth checking whether the under-sink isolation valves actually turn — or whether the whole flat or house will need shutting down for the job. Having isolation valves serviced or fitted while a plumber is already there is the cheapest future-proofing in this trade.

Hard water versus your taps

Taps are where Richmond’s water shows itself daily. Thames Water confirms all the water in its region is hard — it classifies anything over 300 mg/l of calcium carbonate as very hard¹ — and the tap is the very end of the pipe: scale crusts the aerator, stiffens ceramic cartridges, seizes headgear threads and leaves the white tide-marks every Richmond kitchen knows. Three practical consequences. First, cartridges and washers here are service items, not lifetime parts — budget for the occasional swap rather than treating each one as a failure. Second, descaling the aerator is legitimate DIY: unscrew it, soak it, refit it. Third, if you’re considering a softener for the scale, note Thames Water’s own advice: softened water isn’t recommended for drinking or cooking, so installations should keep a separate unsoftened drinking tap¹ — a detail that decides kitchen tap choice before anyone opens a catalogue. The borough-wide picture is in our London Hard Water guide.

Choosing a new tap — match the tap to the house

The most common new-tap disappointment in older Richmond homes isn’t quality; it’s pressure mismatch. Some older Richmond homes, including Victorian and Edwardian properties, still run gravity-fed hot water from a loft tank, and a tap designed for high-pressure systems will dribble on a low-pressure supply no matter what it cost. Before choosing, know what feeds the tap: gravity tank, combi boiler or unvented cylinder — and check the tap’s minimum pressure rating against it. A plumber can tell you in one look at the airing cupboard.

Beyond pressure: kitchen mixers must keep hot and cold appropriately separated or check-valved depending on design; pull-out spray taps carry their own cartridges and hoses (more to scale, more to service); and on cheaper taps the spare-parts question answers itself — there aren’t any. Spending a little more on a tap whose cartridges are stocked in the UK is the difference between a ten-minute repair and a replacement in five years.

For garden and outside taps, the specification is isolation and drain-down for winter (the freeze-and-burst logic on the Burst Pipes page) plus backflow protection, normally a double-check valve, so garden water can’t be drawn back into the drinking supply — and in Barnes, Kew, Ham or Hampton homes with long garden runs and outbuildings, internal isolation and a proper autumn drain-down are what keep an outside tap from becoming a winter burst-pipe callout.

For cafés, shops and offices in Richmond, Twickenham or East Sheen, high-use taps and staff or customer washrooms bring their own demands — durable cartridges, accessible isolation, work timed around trading — which is Commercial Plumbing territory.

Installation done properly

Tap installation is small enough that corners get cut and regulated enough that they shouldn’t be. The Water Supply (Water Fittings) Regulations 1999, Regulation 4 requires water fittings to be of an appropriate quality and standard and to be installed in a workmanlike manner² — which in practice means a proper installation includes: serviceable isolation valves on the supplies (so the next repair doesn’t shut the house down), flexible connectors or rigid tails fitted without strain, the right backflow protection for the application, joints made and tested rather than “snugged and hoped,” and the old tap’s seat checked rather than blamed. One mark of a careful installer: you can look any plumber up on WaterSafe, the national register of approved plumbers recognised by the water industry for exactly this kind of fittings work.

Renting? With 24.7% of the borough’s households renting privately per the Office for National Statistics,³ the usual split applies: a tap that’s worn out is generally the landlord’s repair — report drips in writing early, because on a metered supply whoever pays the water bill pays for the wasted water. RHP tenants: tap repairs route through Richmond Housing Partnership on 0800 032 2433⁴ — the stock transferred from the council in 2000⁵ — so report before paying privately.

What tap work costs in Richmond upon Thames

Each listed plumber sets their own prices and quotes directly — these figures are an editorial guide to the local range, nothing more.

Editorial estimates only — not regulated rates, not market data. Two questions sharpen any tap quote: is the cartridge identified and included, and will isolation valves be fitted or freed while the water’s off? Our How to Read a Plumbing Quote guide covers the rest; the London Plumbing Costs & Compliance Guide has the wider picture.
