Coverage: general plumbing across Welling’s DA16 postcodes — the town centre and station, the High Street and Bellegrove Road, and towards Falconwood, East Wickham and the Danson/Bexleyheath edge.
What this covers: the everyday repairs, replacements and small installs — leaks and drips, isolating valves, stopcocks, waste and trap work, ballvalves and overflows, outdoor and utility plumbing, and the jobs that don’t sit neatly under one service.
Where to start: if your job is clearly an emergency, a drain, a toilet, a tap or a boiler, those pages carry more specific detail; use this page for everything else — or if you’re not sure which trade you need.
Costs: indicative Welling ranges are under Costs — editorial estimates only.
Availability: each plumber sets their own hours, shown on their profile.
Who’s responsible for what in Welling
Responsibility depends on which pipe or fitting is affected. In Welling:
- Clean water is supplied by Thames Water — Bexley sits within its supply area.1 Public and shared sewers are maintained by Thames Water.7 Thames Water owns the water mains and the communication pipe to your boundary; you own the supply pipe from the boundary into the home and all internal pipework, although shared supply pipes can be jointly owned by neighbouring properties.2 A blocked public or shared sewer is reported to Thames Water on 0800 316 9800.
- Surface water on roads and highway gullies is the council’s — Bexley handles flooded public roads and blocked gullies and directs private-property drainage enquiries to Thames Water.3 That reporting route does not make Thames Water responsible for every private drain: the owner is generally responsible for waste pipes within the boundary that serve only that property, while Thames Water maintains public sewers and shared sections.7
- Gas isn’t a plumbing job in the first instance — if you smell gas, do not operate electrical switches or use naked flames; leave and call the National Gas Emergency Service on 0800 111 999 from outside.8
- If you rent, social tenants should report repairs to their registered housing provider — Bexley owns no housing stock.4 Private tenants tell their landlord or agent first.
Private pipework serving only your property from the boundary inward — the everyday leaks, valves, wastes and small installs — is where a general plumber comes in. Shared supplies, communal pipework and lease or tenancy terms can change who is responsible.
What “general plumbing” covers
It’s the catch-all: fixing a leak under the sink, replacing a worn stopcock or isolating valve, sorting an overflow or a noisy ballvalve, re-plumbing a waste or trap after a unit change, plumbing in an outdoor or utility supply, and the dozens of small jobs that keep a home running. Any work that touches the drinking supply should comply with the Water Supply (Water Fittings) Regulations 1999, which is one reason to use a verified plumber — and, for water-fittings competence, to check the WaterSafe register.5
Welling is in Thames Water’s hard-water region, so limescale can contribute to restricted valves and fittings, but it should not be assumed to be the cause.6 For a leak beneath a sink, the plumber should first dry the area and distinguish condensation from active leakage, then check the supply joints, flexi hoses, tap base, waste joint, trap and appliance hoses before replacing parts. Water from a tap base or appliance hose can track along cabinetry and make the visible trap appear to be the source. Low flow should be compared at other outlets and checked against the local valve, main stopcock and any shared supply.
For a running overflow or noisy float valve, the plumber should check the float movement, water level and valve seating before replacing the valve; where a cold-water storage cistern is involved, the water level, warning pipe and valve shut-off should also be checked. A normal first visit can often isolate a leak, replace a standard trap, valve or float valve, and test the repair both under supply pressure and while the sink and any connected appliance discharge. A return visit may be needed where the stopcock will not close, the isolation interrupts a shared supply, access requires a landlord, freeholder or managing agent, or an uncommon part has to be ordered. A defective water-company boundary valve may need referral to Thames Water. Opening boxing, flooring or fitted units becomes trace-and-access work and may require approval from the landlord, freeholder or insurer before destructive access begins. If communal pipework is involved, the plumber may temporarily isolate or otherwise make the area safe where authorised, photograph the leak and moisture evidence, record the repair limitations, and refer permanent work to the responsible freeholder or manager rather than undertake an unauthorised alteration.
Find a verified general plumber by Welling area
- Welling town centre & station (DA16) — in a flat above commercial premises or a converted house, concealed branches may pass through a shop or shared area, and water can appear on a shop ceiling or in the flat below some distance from the actual leak. The plumber should confirm whether the branch or riser is private or communal, coordinate access where the shop remains open, document the visible damage and moisture evidence, and obtain landlord, freeholder or managing-agent authority before isolating shared pipework or opening concealed areas.
- Falconwood & East Wickham — where a utility connection is being added, the plumber should provide an accessible isolating valve and suitable trapped waste rather than extending unsuitable fill or drain hoses. Confirm the postcode near the Greenwich boundary at Falconwood.
- Danson & the Bexleyheath edge — where a suburban house has a cold-water storage cistern, a running warning pipe should be traced by checking the float, water level and valve seating before the valve is replaced. For low flow or a seized stopcock, the plumber should compare several outlets, check whether the boundary valve is accessible and establish whether the supply is shared before replacing internal fittings.

Frequently asked questions
The everyday jobs that don’t fit a single category — leaks, valves, stopcocks, wastes, overflows and small installs. If it’s an emergency, drain, toilet, tap or boiler, those pages carry more specific local detail.
The supply pipe from your boundary into the home and all internal pipework serving only your property are generally your responsibility; shared supply pipes may be jointly owned by neighbours. The mains and communication pipe to the boundary are Thames Water’s.2
It varies by plumber — many charge an hourly or first-hour rate, some quote per job. Ask before they attend; each listed plumber sets their own.
Your registered housing provider — Bexley owns no housing stock.4 For an active leak, use local isolation only if it is safe and report the emergency through the provider’s repair route; a plumber may make the area safe but should not carry out unauthorised permanent work on communal pipework.

Why verified plumbers — not a general directory
General plumbing is where “any plumber will do” costs people the most — so we check that a plumber is genuine, insured and competent before you hand them the everyday jobs.
Every listing 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 Welling’s DA16 postcodes before a profile is approved — and we keep an eye on customer feedback gathered from across the web. Most general plumbing is wet work and doesn’t require Gas Safe registration; where a job involves gas, we confirm Gas Safe registration directly with the Gas Safe Register, and for water-fittings work you can look a plumber up yourself on WaterSafe.
Listed plumbers pay a flat monthly fee to be listed. What that fee never buys is the verification itself — every listing is checked on the same terms — and there’s no per-enquiry middleman fee, so your enquiry goes directly to the plumber. Profiles may be suspended or removed if credentials lapse or credible concerns are raised; see the full verification process →.

A general plumber should diagnose the fitting before replacing parts and should stop where isolation, communal pipework or responsibility requires action by Thames Water, a landlord, freeholder or managing agent.
