What actually counts as a plumbing emergency
Not every leak needs a 2am call-out, and knowing the difference saves you money. Royal Greenwich treats a genuine housing emergency as things like no drinking water supply, burst pipes with a leak you cannot stop, and blocked drains and toilets causing flooding, and for its own tenants it aims to make those safe within two hours. A slow-filling cistern or a single blocked basin is urgent at worst, not an emergency — Royal Greenwich schedules a blocked basin within three working days and a leaking cistern or pipe within one. A simple dripping tap is a routine repair rather than an emergency.
The practical test for a Woolwich home is simple: is water escaping faster than you can contain it, is it near your electrics, or have you lost all water or all heat? If yes, act now. If no, you have time to get a fair quote rather than pay emergency rates.
Gas or carbon monoxide is not a plumber call
This is the one routing mistake that can cost lives, so it comes first. If you smell gas, suspect a leak, or a carbon monoxide alarm sounds, National Gas is unambiguous: call the National Gas Emergency Service on 0800 111 999, 24 hours a day and free to call. While you wait, National Gas advises opening doors and windows, not touching electrical switches, and turning off the gas at the meter control handle unless the meter is in a cellar.
For a suspected carbon monoxide leak specifically, the same guidance is to stop using appliances, evacuate, and call 0800 111 999 or the HSE Gas Safety Advice Line on 0800 300 363, then seek medical help. A plumber — even a Gas Safe one — is not your first call in that moment. Once the emergency is made safe, gas appliance and boiler work must be done by a Gas Safe registered engineer, which is a separate step.
Who to call first depends on how you hold your Woolwich home
Woolwich has an unusually mixed housing profile — council tenancies, leasehold flats, private rentals, housing-association homes and owner-occupied houses often on the same street. Who responds in an emergency depends on which of those you are.
Council tenants report emergencies straight to Royal Greenwich, not a private plumber. For an urgent problem such as a leak that will not stop, the council asks tenants to call 020 8921 8900 between 9am and 5:30pm Monday to Thursday and until 4:30pm on Friday, and 020 8854 8888 at all other times; there is also a free line for new repairs, 0808 175 6915, on weekdays from 9am to 5pm.
Leaseholders in a Royal Greenwich block sit on a split. The council’s own repair table makes leaseholders responsible for baths, sinks, showers, toilets, taps and pipework, and for gas, water and electricity pipes that only serve their home — the pipes after the stopcock, while the council keeps responsibility for the structure, communal areas and the pipes running up to your home, up to the stopcock. So an internal burst is usually your call to arrange; a leak in the riser or a shared stack may not be.
Private tenants should press the landlord first for anything non-dangerous, but Royal Greenwich runs an emergency safety net. Its Residential Services team has powers over serious hazards such as sewage leaking into the house, no hot water and no drinking water, on 020 8921 8157. For less serious leaks, the council’s rule is to tell the landlord in writing and give them 14 days to respond before escalating.
Housing-association tenants go through their landlord’s own emergency repair line first. Homeowners are free to call a private emergency plumber directly — which is where this directory comes in.
Flats on the Royal Arsenal heat network are different
This catches people out at Royal Arsenal Riverside. Those apartments are heated by a district energy scheme, and the operator, SSE, describes each home as regulated by a heat interface unit so that individual gas boilers and hot water storage units are eliminated. SSE also states it maintains and repairs the HIUs and the energy centre under a 20-year contract.
In plain terms: if you have no heat or no hot water in one of these flats, that is a heat-network fault for the managing agent or heat supplier — not a boiler engineer, because there is no boiler. A genuine water leak from the pipework or radiators inside your flat can still be a plumber’s job, subject to your lease. Getting this right stops you paying a call-out for a fault you cannot legally have someone touch. Woolwich Exchange is proposed to use a low-temperature district energy network too, so this is a recurring Woolwich pattern rather than a one-off.
When a private emergency plumber is the right first call
Strip out the gas, the council routes and the heat networks, and a large share of Woolwich emergencies land squarely with a private plumber — and quickly. If you own your home, or you’re a leaseholder dealing with an internal burst, or a homeowner with a flooding bathroom, a verified emergency plumber is exactly who you want. Typical genuine call-outs: a burst supply pipe under a sink, a failed flexible tap connector spraying a kitchen, an overflowing cistern, a leaking cylinder, or a blockage backing up sewage into a ground-floor toilet.
Before anyone attends, know two things: where your stop tap is, and whether the water is near electrics. Both are covered in the next section, and in more depth on our burst pipes page.
While you wait: making a Woolwich emergency safe
The single most useful thing you can do is turn the water off at the stop tap. Thames Water notes the inside stop valve is usually under the kitchen sink — turn it clockwise to close it. If water is anywhere near sockets or the consumer unit, switch the electrics off at the mains. Then contain what you can with towels and buckets, and photograph everything for insurance before a plumber starts work.
If the leak is on a shared drain or a public sewer rather than your own pipes, that may be Thames Water’s responsibility rather than a job you pay for — they own public sewers and any drains you share with neighbours. Our find your stop tap guide walks through locating and testing yours before you ever need it.
Why verified plumbers in Woolwich
A national directory will show you whoever pays for the slot. That’s the opposite of what you want at 2am. Every plumber listed here is checked before they appear — identity, insurance, trading presence and Gas Safe registration where gas work is involved — and re-checked annually, so the badge means something on the night you need it. We take a flat monthly listing fee from plumbers, so there’s no customer-side introduction fee and no pay-to-play ranking buying someone the top spot. Workmanship-guarantee badges on each listing tell you upfront whether a plumber stands behind the job for 1, 3, 6 or 12 months.
Frequently asked questions
If the leak is one you cannot stop, yes — Royal Greenwich lists an unstoppable burst among the problems it treats as an emergency.
If you can isolate it at the stop tap and contain it, it becomes urgent rather than an emergency, and you can get a proper quote instead of paying emergency rates.
Royal Greenwich, not a private plumber.
Out of normal office hours the council asks tenants to call 020 8854 8888 for emergencies.
Arranging your own plumber can leave you paying for work the council would have covered.
No.
Call 0800 111 999 or the HSE Gas Safety Advice Line on 0800 300 363, evacuate, and seek medical help.
Gas engineer work comes only after the emergency is made safe.
Often not.
Many of those flats run on a shared heat network with a heat interface unit instead of a boiler, so heat and hot-water faults route to the managing agent or heat supplier.
A water leak inside the flat can still be a plumber’s job.
That’s set by the individual plumber, not the directory — we don’t add any customer-side fee.
Ask for the call-out charge and hourly rate before they attend; our how to read a plumbing quote guide explains what to check.
