Coverage: emergency help across Welling’s DA16 postcodes — the High Street and town centre, Falconwood, East Wickham, Upper Wickham Lane and the Danson side.

What this covers: uncontainable leaks, no water, burst pipes, overflowing drains and toilets, and making a property safe before a full repair.

Not sure this is the right page? For a sudden burst specifically, see Burst Pipes; for a slow or hidden leak, Leak Detection; for a blocked drain, Blocked Drains.

Availability: each plumber sets their own hours — same-day and out-of-hours cover is shown on their individual profile.

What counts as a plumbing emergency — and what to do first

A genuine emergency is water you can’t contain, a total loss of water, or anything creating a safety risk — a burst pipe, a failed cylinder, an overflowing soil stack, or a leak reaching electrics. The first move is almost always the same: find your stop tap (usually under the kitchen sink) and turn it clockwise to cut the water, then open the cold taps to drain the system down.¹

Knowing where your stop tap is before an emergency is half the battle — our guide on finding it is linked below. If water is near electrics, keep clear and switch off at the consumer unit only if it’s safe and dry; if you smell gas, treat it as a gas emergency, not a plumbing one (see Safety first).

Not everything that looks like an emergency is yours to fix, though — which is where local routing saves time and money.

Who fixes what in Welling

Welling’s drinking water is supplied by Thames Water, as Bexley is within its drinking-water supply area.² Thames Water also provides wastewater services in Bexley.¹² That gives a clear split in an emergency:

A burst main in the street is Thames Water’s. No water across several homes may indicate a public-main problem, a shared supply or a wider outage, so check Thames Water incidents and confirm the supply arrangement before assigning responsibility. Thames Water is responsible for the communication pipe up to your boundary.³
A burst on your supply pipe (boundary into the house) or any internal pipework is yours — a plumber’s job, or your landlord’s in a rented home.³
An overflowing public sewer goes to Thames Water on 0800 316 9800.⁴
Water flooding a road or driveway after heavy rain may be surface water, a highway-drainage problem, a public-sewer surcharge or private drainage. Bexley’s technical paper identifies surface water as the principal flood source across Welling and Falconwood,¹³ but the responsible party depends on the asset where the fault is found.

If you rent from a housing association, note that since 27 October 2025 Awaab’s Law has treated a significant leak or total loss of water as an example that may qualify as an emergency hazard where it presents an imminent and significant risk of harm, assessed case by case and with regard to the occupier’s circumstances. If the landlord’s investigation confirms an emergency hazard, the investigation and relevant safety work must both be completed within 24 hours (Bexley itself owns no housing stock, so this falls to your provider).⁶

For no water, test another outlet, ask whether neighbours are affected, confirm that the internal stop valve is open, check the meter and then check Thames Water incidents. Several affected properties can indicate a public main, a shared supply or a wider outage. Closing the mains stop valve will not necessarily stop water from a storage tank or isolate a sealed heating circuit, and several backing-up fixtures point more towards a soil stack or drain restriction than a fault in one toilet. A first visit may isolate the affected branch, but communal-valve access, concealed pipework, specialist leak detection, drain jetting or CCTV, and unavailable parts can require follow-up.

Safety first

Water and electricity. If water is dripping near or onto sockets, light fittings, the consumer unit or wiring, keep clear and switch the electricity off at the consumer unit only if it’s safe and dry to do so — otherwise wait and keep everyone away. Switch off the boiler or immersion heater too, and don’t use electrical appliances in a flooded area.

If you smell gas or suspect a leak, follow the official emergency guidance:⁷¹⁵

1. Don’t switch anything electrical on or off, don’t use a naked flame, don’t smoke.

2. Open doors and windows if it’s safe to do so.

3. If the meter control handle is known and safely reachable, turn the gas off at the meter — unless the meter is in a cellar.

4. Leave the property and get into fresh air immediately.

5. Call the National Gas Emergency Service on 0800 111 999 from outside, and don’t go back in until a gas engineer gives the all-clear.

Carbon monoxide is a colourless, odourless gas a poorly-running appliance can produce. The NHS lists the main symptoms as headache, dizziness, nausea, breathlessness, collapse and loss of consciousness — often mistaken for flu, but without a fever, and easing when you leave the building.⁸ As general safety guidance, Gas Safe Register recommends an audible carbon-monoxide alarm meeting BS EN 50291 in rooms containing fuel-burning appliances, installed in accordance with the manufacturer’s instructions.⁹

Gas work is restricted by law. Only a Gas Safe registered engineer may work on a gas appliance or its pipework — ask to see the Gas Safe ID card.¹⁰ Wet work — water pipes and radiators — doesn’t require registration, but the gas boiler itself and its connections do.

Find a verified emergency plumber in Welling, by area

Welling town centre & High Street: flats above shops on the Watling Street line, where a burst on an upper floor can come through into the unit below and isolating it may mean a shared stop tap or riser.
Managed flats and maisonettes in Welling: the internal stop valve may not isolate a communal riser, and a leak can travel into another flat or a shop below. The block manager or freeholder may need to provide access to a service cupboard, the affected unit or the ceiling below.
Falconwood (DA16/SE9 border): suburban homes near the A2, on the Greenwich edge — confirm exact postcode and supplier routing at the boundary.
East Wickham & Upper Wickham Lane: later kitchen refits can leave stop valves boxed in or relocated, while older tank-fed systems and cylinders may continue releasing water after the incoming mains is isolated.
Danson & Welling Way: longer private supplies may run beneath paths, drives or later extensions, so meter checks and leak detection can be needed before opening ground.

What it costs

Editorial estimate only — indicative labour ranges for the Welling (DA16) area, NOT regulated rates, NOT market data, NOT a published cost survey. Get written quotes. Welling is inside the London-wide ULEZ but outside the central Congestion Charge zone, which can affect call-out pricing.¹¹

Job	Indicative range	Notes
Emergency / out-of-hours call-out	£120–£250+	Nights, weekends and bank holidays cost more
Make-safe / isolate and drain down	£100–£200	Stabilising before a full repair
Accessible burst or leak repair	£150–£350	Exposed, easy to reach
Leak in a wall, floor or buried run	£300–£600+	More where access and reinstatement are involved
Clear an overflowing drain / WC	£100–£250	More for jetting or a shared sewer

Frequently asked questions

Turn off the stop tap (usually under the kitchen sink) to cut the water, open the cold taps to drain down, keep clear of any electrics, and call a verified plumber. Knowing where your stop tap is in advance makes all the difference.

Thames Water — frozen or burst pipes

An internal leak you can’t contain is a plumber’s job. A burst main, a wider no-water incident or an overflowing public sewer goes to Thames Water (0800 316 9800). Road flooding after rain may involve highway drainage, a Thames Water sewer, private drainage or another asset, so responsibility depends on where the fault is found.

Thames Water — report a blockage

No. Leave the property and call the National Gas Emergency Service on 0800 111 999 from outside. Don’t switch anything on or off, and don’t go back in until it’s cleared.

National Gas — emergencies

Your housing association (Bexley owns no stock). A significant leak or total loss of water may qualify as an emergency hazard where it creates an imminent and significant risk of harm. If the landlord confirms an emergency hazard, the investigation and relevant safety work must both be completed within 24 hours.

GOV.UK — Awaab’s Law

Often the first job is to make the property safe — isolating, draining down, or a temporary repair — with the permanent fix following once parts, access or drying-out are sorted.

Why verified plumbers — not a general directory

In an emergency, the last thing you want is to gamble on whoever appears first in a search — so checking that a plumber is genuine, insured and contactable matters before the crisis, not during it.

Every listing is checked before it goes 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. Where gas work is involved we confirm Gas Safe registration directly with the Gas Safe Register. For water and fittings work you can also look a plumber up yourself on WaterSafe, the free, water-industry-backed national register.¹⁴

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 regardless of how much a plumber spends with us — 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 →.
