Ealing’s plumbing picture: seven towns, two water suppliers

Ealing Council treats the borough as seven towns — Acton, Ealing, Greenford, Hanwell, Northolt, Perivale and Southall.¹ Less well known: the borough’s drinking water is split between two companies. The council’s Infrastructure Delivery Plan maps the borough’s potable supply as divided between Thames Water and Affinity Water — Affinity serving much of the western side, Thames Water the east.² Supplier boundaries don’t follow town signs neatly, so for a specific property the safe move is a postcode check with the water company.

Both sides are hard-water territory. Affinity Water draws around 60% of its supply from groundwater that has passed through chalky limestone, which is what makes its water hard³, and Thames Water says the same of its region.⁴ The Drinking Water Inspectorate notes that hard water causes scaling in hot water systems, kettles and domestic appliances, and shortens heating-element life.⁵ In practice: scaled taps, slow showers, noisy cylinders and boiler heat exchangers working harder than they should — borough-wide, whichever company bills you.

Wastewater is simpler: Thames Water is the sewerage undertaker for the whole borough regardless of who supplies your drinking water.² The same council Infrastructure Delivery Plan records that Ealing is at risk of flooding from sewer overflows and capacity issues, with fluvial flood risk concentrated around the River Brent — a designated main river.² The council has also written to Thames Water about sewage entering the River Brent, naming Perivale, central Ealing, Pitshanger and Hanwell as the areas most affected.⁶ Drainage here isn’t an abstract topic — it’s a documented local pressure, and it’s why proper diagnosis matters before anyone pays for a drain callout.

Responsibility splits three ways. Ealing Council sets it out: homeowners and landlords are responsible for drains up to the connection with another property’s drainage; sewers and lateral drains are maintained by Thames Water.⁷ The council’s own gully cleaning page is blunt about the third part: the only drains the council is responsible for are highway gullies.⁸ One Ealing-specific wrinkle worth knowing: for former council houses, the council says responsibility beyond the connection point can sit with the owners, Thames Water or Ealing Council depending on the sewer layout of the estate⁷ — worth checking before commissioning private work on an ex-council street.

Find a verified plumber by town

Acton (W3, parts NW10/W4). A mix that keeps plumbers busy: Victorian and Edwardian streets, flats above shops along the High Street and Churchfield Road, and the borough’s largest regeneration at the former South Acton estate, where Ealing Council says nearly 3,500 new homes are being built across 52 acres, replacing what was once almost 2,100 post-war council homes.⁹ Period pipework and brand-new developer systems sit streets apart.

Ealing (W5, W13). The borough’s commercial heart around Ealing Broadway and Haven Green, ringed by some of west London’s best-known period suburbs — Ealing Common, Pitshanger, Montpelier, the Brentham Garden Suburb — plus interwar estate flats around Hanger Hill. Conservation-area stock means older supply pipes, original soil stacks and careful exterior work; West Ealing adds estate regeneration at Green Man Lane to the mix.

Greenford (UB6, parts UB5). Don’t expect a Victorian story here — Greenford’s plumbing identity is suburban interwar housing, the Golf Links estate’s maisonette blocks and towers in the south, and industry along the canal. Green space frames it: Horsenden Hill, which Ealing Council describes as the borough’s largest nature conservation site at 100 hectares, sits on its doorstep.¹⁰

Hanwell (W7, parts W13). Compact, old and distinctive: a Victorian core around Hanwell Broadway, the interwar Cuckoo Estate to the north, and the Grand Union Canal’s Hanwell lock flight with Brunel’s Wharncliffe Viaduct nearby. Hanwell was one of the four areas the council named in its River Brent letter⁶ — drainage awareness is part of working here.

Northolt (UB5). Suburban and practical: the town centre runs south of the station along Mandeville Road and Church Road, with housing that’s mostly interwar, post-war council-built and newer infill rather than period stock. In the post-war blocks and maisonettes, a leak or pressure problem can involve a communal riser or shared isolation valve rather than a simple under-sink stop valve — worth establishing before work is quoted. New apartment blocks are arriving through council-led schemes, bringing modern systems with their own conventions.

Perivale (UB6). A 1930s suburb wrapped around the A40, with the Art Deco Hoover Building as its landmark and an industrial estate that keeps commercial plumbing in the picture. Perivale carries a distinction no other Ealing town has: the council’s immediate Article 4 direction on small HMOs took effect here first, on 30 October 2024.¹¹

Southall (UB1, UB2). The busiest mixed-use plumbing territory in the borough: terraced streets, flats above the Broadway and South Road shopping parades, high-demand family housing, and large-scale new build at The Green Quarter on the former gasworks, where Ealing Council records planning permission for 3,750 new homes, 931 of them affordable.¹² Behind the parades, food premises and the flats above them often share rear drainage runs, so kitchen grease and residential waste problems can land in the same pipework. Norwood Green adds a heritage pocket to the south.

Who to call first in Ealing

Not every problem starts with a private plumber — and a directory that pretends otherwise isn’t doing its job. The quick map:

Smell gas or suspect carbon monoxide? Don’t book a plumber first. No switches, no flames, no smoking; open doors and windows; turn the gas off at the meter if it’s safe and reachable; leave if the smell is strong; call the National Gas Emergency Service free on 0800 111 999 from outside.¹³

Ealing Council tenant? Report repairs through the council, not a private plumber. Ealing Council aims to attend emergency call-outs within 4 hours, subject to demand, making the situation safe with follow-on work in normal hours¹⁴ — and out-of-hours emergencies (weekends, bank holidays, 5pm–8am) go to 0800 181 744 or 020 8825 5682, not online.¹⁵

Blocked sewer or lateral drain — or several homes affected? That’s Thames Water’s pipe, not yours: 0800 316 9800.⁷

Flooded road gully? Council, not plumber: 020 8825 6000.⁸

Private renter? Report repairs to your landlord first unless it’s an immediate safety emergency.

Everything else — your own home, your own pipework, your own appliances — is exactly what the verified plumbers listed above are for.

What plumbing costs in Ealing

There is no official Ealing Council or government price list for private plumbing work — anyone claiming “council rates” is inventing them. Prices depend on the job, access, urgency, parts and timing. For context, British Gas puts a one-off boiler service at £109 in its boiler servicing guide¹⁶ — a national provider benchmark at the time of review, not an Ealing price. Indicative ranges:

Editorial estimate only, for orientation. These are NOT regulated rates, NOT market data and NOT a published cost survey — always get a written quote. Ask about the callout charge, hourly rate, minimum charge and parts mark-up before booking.

Two local cost factors: Ealing sits inside London’s ULEZ¹⁷ but outside the central Congestion Charge zone, and the council’s infrastructure evidence records half the borough’s road network as covered by controlled parking zones — 54 CPZs in all² — with Ealing Council selling contractors a temporary CPZ permit at £15 per day¹⁸, which longer jobs may reasonably pass on.

Frequently asked questions

Why verified plumbers — not a general directory

Ealing has an unusual reason to care about verification: both of its water companies point customers in the same direction. Affinity Water suggests getting quotes from plumbers registered with WaterSafe³, the free, water-industry-backed national register — and you can look any plumber up there yourself.

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. Where gas work is involved, we confirm registration directly with the Gas Safe Register — and on any gas job, ask to see the engineer’s Gas Safe ID card before work starts. 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.
