What this covers: running and overflowing cisterns, weak or failed flushes, leaks at the pan or cistern, seized handles, fill and flush valve replacements, and full toilet replacement.
Not this page: a toilet that won’t drain — especially with other fixtures gurgling — is often blocked drains; a wider bathroom refit is bathroom plumbing.
Costs: most repairs are at the small end of plumbing prices — see what it costs.
Availability: routine bookings for most faults; an overflowing toilet you can’t isolate is an emergency.

What’s actually wrong with it

Toilet faults sort into four families, and the symptom usually names the part. Constant running or trickling into the bowl is the valve pair: either the fill valve isn’t shutting off (water creeps up and escapes down the overflow into the bowl) or the flush valve seal isn’t seating (the cistern slowly drains into the pan and refills, on a loop). A weak or incomplete flush is usually a flush-valve, siphon or linkage problem, a cistern not filling to its line, or — in older toilets — scale narrowing the rim jets. Leaks you can see divide by location: at the cistern-to-pan joint it’s typically the doughnut washer or bolts; at the floor it can be the pan connector — which matters more, because that’s waste water. And a toilet that won’t drain may not be the toilet at all: if a plunger doesn’t shift it, or other fixtures gurgle when you flush, the blockage is downstream on the waste or stack — that’s blocked drains territory, and worth diagnosing before paying for the wrong visit.

Two special cases earn their own line. In flats, a toilet that gurgles, backs up repeatedly or affects other fixtures may be a shared soil-stack problem rather than a faulty pan — the council, freeholder or managing agent may need to be involved before any private repair makes sense. And macerator toilets — common where a loft conversion, basement bathroom or back addition sits away from the main soil stack — need separate diagnosis: a unit that hums, trips, smells or backs up may have a pump, non-return valve or discharge-pipe fault rather than a toilet problem at all.

Two useful facts for the phone call: the model or a photo of the cistern internals helps the plumber arrive with the right valve, and the isolation valve on the cistern’s supply pipe (a screwdriver slot, quarter-turn) lets you stop a running toilet without shutting the house down.

The leaky loo: Ealing’s quietest water bill

A toilet leaking clean water into its own bowl doesn’t flood anything — which is exactly why it runs for months. Thames Water puts numbers on it: a leaky loo wastes an average of around 400 litres of water a day — five full bathtubs — with even a small trickle wasting up to 200 litres a day at an extra £161.33 per year, and visibly rippling water likely to waste 600 litres a day at £483.99 per year.¹ On a metered supply, a £100-odd valve repair can pay for itself within months.

The check costs nothing: look for water trickling, rippling or flowing at the back of the bowl long after a flush¹ — or wipe the back of the dry bowl, lay a strip of toilet paper against it, and see if it wets without a flush. In a household with more than one toilet, check them all; the quiet one is usually the guilty one.

Hard water and your cistern

Both sides of split-supply Ealing are hard-water territory — Affinity Water attributes its hardness to chalky-limestone groundwater² and Thames Water says the same of its region³ — and the Drinking Water Inspectorate links hard water to scaling in water systems and appliances.⁴

A toilet cistern feels that directly. Scale stiffens fill-valve mechanisms and stops seals seating cleanly — a common root cause behind the leaky-loo trickle — and it narrows the rim jets, which is why an older Ealing toilet can flush weakly with nothing mechanically wrong. The practical responses are modest: descale the rim jets, replace rather than endlessly adjust a scaled valve (modern fill and flush valves are inexpensive), and treat repeat valve failures as the hard-water tax they are rather than bad luck.

Replacements done right

When repair tips into replacement — a cracked pan, an obsolete cistern, or a valve-by-valve money pit — a few quiet checks separate a good job from a future problem. First, fit: pan outlet position, soil-pipe alignment, floor fixing and cistern access all need checking before assuming any close-coupled toilet will go where the old one was. Second, fittings compliance: under the Water Supply (Water Fittings) Regulations 1999, water fittings must be of appropriate quality and standard, suitable for the circumstances and installed in a workmanlike manner.⁵ No particular approval scheme is mandatory, but certification is how products demonstrate compliance in practice — WRAS itself says its certification can be used to demonstrate compliance to Regulation 4⁶, with NSF REG4¹³ and Kiwa KUKreg4¹⁴ as recognised equivalents. Reputable plumbers fit compliant valves and connectors as a matter of course; it’s still a fair question to ask.

Third, the waste side: the pan connector and waste pipework are a drainage matter rather than a water-fittings one, and getting the seal and fall right is what keeps a new toilet from becoming a floor leak. If old sanitaryware is being taken away, ask whether lawful disposal is included in the quote — an old pan is trade waste, not something for the household bin, and GOV.UK is clear that a business that transports waste must be registered with the Environment Agency as a waste carrier.¹²

Who fixes it in rented homes: sanitation installations sit squarely within the landlord’s repairing obligations under Section 11 of the Landlord and Tenant Act 1985⁷ — report faults to your landlord first. Council tenants report through Ealing Council’s repairs routes — 0800 181 744 or 020 8825 5682 for emergencies⁸ — rather than booking privately.

Find a verified plumber for toilet repairs by district

An honest note first: a fill valve fails the same way in Acton as it does in Northolt — toilet repair is one of the least postcode-dependent jobs in plumbing. What does vary across Ealing is the housing around the toilet:

Acton (W3, parts NW10). Newer blocks such as the Acton Gardens phases⁹ may include wall-hung pans or concealed cisterns, where access panels, flush plates and the right proprietary spares matter more than the right wrench. In the period terraces, it’s the opposite era: older cisterns where parts may need matching or sensible modernising.

Ealing (W5, W13). Converted flats mean a toilet leak at the floor is the downstairs neighbour’s ceiling — pan-connector and seal faults deserve prompt attention here, and proving whose water it is starts the conversation (see leak detection).

Greenford (UB6, parts UB5) and Northolt (UB5). In estate blocks and maisonettes, a toilet that won’t clear with other fixtures gurgling points at the shared stack rather than the pan — a communal repair through the council or, in private blocks, the freeholder or managing agent, not a private toilet job.

Hanwell (W7). Older bathrooms in older houses: expect the occasional period oddity — high-level cisterns, imperial-era fittings — where a plumber comfortable with sensible like-for-like or conversion choices saves the bathroom from an unnecessary refit.

Perivale (UB6). Interwar originals that haven’t been refitted can be running on decades-old internals; here the repair-or-replace question usually answers itself once the cistern lid comes off.

Southall (UB1, UB2). In larger or extended households in parts of Southall, toilets may see heavier use — so a running cistern or weak flush becomes urgent sooner, especially where it’s the only toilet. The leaky-loo check above is worth running in every bathroom, because on a meter the waste multiplies per toilet.¹

What it costs

Toilet work sits at the affordable end of plumbing — which is exactly why it’s worth fixing promptly rather than living with the trickle. Ask whether the quote includes parts, what brand of valve is being fitted, and whether a return visit is covered if a part needs ordering.

Editorial estimate only, for orientation. These are NOT regulated rates, NOT market data and NOT a published cost survey — parts, access and the toilet itself change the price. Always get a written quote.

There is no official price list for toilet repairs in Ealing. Local cost context: Ealing is inside London’s ULEZ¹⁰, and half the borough’s road network sits in controlled parking zones¹¹. And remember the other side of the ledger: on a metered supply, the leaky loo you’re not fixing can cost more per year than the repair.¹

Frequently asked questions

Why verified plumbers — not a general directory

A toilet repair is a small job — which is exactly the kind of job where an unvetted trader can overdiagnose a £100 valve into a £500 replacement, because who gets a second quote for a toilet? Every listing 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, and we confirm the plumber covers Ealing’s W and UB postcodes before a profile is approved.

For water-fittings work — and a cistern valve is exactly that — you can look any plumber up yourself on WaterSafe, the free, water-industry-backed national register; where any gas work arises on other jobs we confirm registration directly with the Gas Safe Register. Profiles may be suspended or removed if credentials lapse or credible concerns are raised — see the full verification process →

There’s no pay-to-play ranking of listings and no customer middleman fee: enquiries go directly to the plumber.
