Burst pipe at midnight? Water through the ceiling? One call ends the panic. 24-hour emergency plumbing across London and the M25, typical 1–2 hour response, parts on the van.
Emergency plumbing is the rapid-response branch of plumbing for water-related faults that cause active damage or loss of essential services: burst pipes, major leaks, sewage backup, no-heat or no-hot-water in cold weather, and overflowing toilets that cannot be stopped at the cistern. The defining feature is time pressure. Every hour an emergency goes unfixed compounds the property damage and, in winter or with vulnerable occupants, the safety risk.
If water is going somewhere it should not, or you have lost an essential service in a way that cannot wait until morning, that is an emergency. If you are unsure, call us anyway. We will tell you straight whether you need an immediate visit or whether a scheduled appointment will do.
Six categories cover almost every emergency call-out we attend.
Cracked or split pipes flooding the property. A burst pipe can dump 600 litres of water into a building in an hour. Copper, plastic, push-fit, and lead pipes all fail differently. We carry the fittings to repair or replace in one visit.
Water coming through walls, ceilings, or floors. Causes range from radiator valves to dishwasher hoses to soil-pipe joints. Step one is always isolating the supply, then locating and fixing the source.
Losing hot water or heating in cold weather is a same-day emergency, especially with elderly occupants or young children. Causes range from a pressure-loss leak in the system to a failed cylinder, pump, or thermostat, and we carry parts for the most common faults.
Drains overflowing inside the property is a health hazard, not just a plumbing problem. We clear, diagnose the cause (root ingress, scale, collapsed pipe, fat blockage), and report back.
More on blocked drainsA toilet that will not stop running or that has overflowed past the cistern. We isolate, clear, and reset the float or replace the cistern internals on the spot.
More on blocked toiletsWinter pipe failures, before or after a freeze. We thaw, locate the crack, and repair before it bursts. Loft pipes and external supply runs are the most common locations in London buildings.
Four outcomes that separate us from the average emergency-plumber search result.
1–2 hour response across London and the M25. We isolate, contain, and stabilise on the first visit even if the full fix lands the next day. The leak stops, the bucket gets emptied, the property dries.
Our emergency line runs around the clock, including bank holidays. You speak to a real person who dispatches a plumber, not a call centre that books you in for tomorrow.
If your emergency involves electrics as well as plumbing, such as an immersion heater fault tripping the consumer unit or a washing-machine leak shorting the kitchen ring main, we handle both trades in one visit. No calling a second company at 11pm.
12-month workmanship guarantee on every emergency repair, backed by £5M public liability insurance. If the same fault returns inside the warranty window, we come back at our cost.
The same five-step process every emergency follows, from a stuck stopcock at 8pm to a burst main at 3am.
Tell us what is happening, where, and how bad. We will give you immediate advice to limit damage while we are on our way: turn off the stopcock, isolate the heating system, and contain the water.
You get a target arrival window. Most emergencies are reached within 1–2 hours during working hours; out-of-hours calls within 2 hours where roads are clear.
The plumber assesses the situation, identifies the cause, and explains exactly what’s needed before starting any work. We isolate and stabilise first, fix second.
Most emergencies are resolved on the first visit. If parts need ordering, we make the area safe and book the follow-up visit as part of the same job.
We test, walk you through the work, and clean up, with a written 12-month guarantee on every emergency repair.
According to the Association of British Insurers, escape-of-water claims are the single most common cause of household insurance loss in the UK, costing the industry billions every year, with most damage occurring in the first hours after the leak begins. The right emergency plumber, reaching the property fast and isolating the supply correctly, is the single biggest determinant of the final repair bill.
Every plumber on our team is fully qualified, fully insured, and highly rated on Google and Checkatrade. We carry the most common fittings and parts in every van so emergency repairs are completed in a single visit, and our multi-trade team handles plumbing-electrical crossover faults without calling a second company.
ARI Maintenance is led by Arianne ‘Ari’ Raofi, founder, who built the company in March 2025 to give London property owners one accountable team for every trade, including the 3am call-outs. Ari personally signs off all major emergency work and is on call for the largest jobs (full re-plumbs after burst-pipe damage, commercial water emergencies). Day-to-day emergency response is handled by named, qualified members of the team backed by Ari and James’s diagnostics.
“Emergency plumbing is half about the fix and half about the panic. The fix has to be right, but the customer also needs to know within five minutes of the call that someone competent is coming. Both halves matter equally.”
Four steps that limit the damage between calling us and our arrival.
Usually under the kitchen sink, in a downstairs cupboard, or where the mains enters the property. Turn clockwise to shut off. If you cannot find it, the external water meter outside has a shut-off valve.
If the leak involves your heating system, turn it off at the programmer or the fused isolation switch nearby. This stops the system pumping more water into the leak.
Towels, buckets, bowls. If water is bulging through a ceiling, poke a small hole in the bulge with a screwdriver to drain it into a container, otherwise the plaster collapses and you lose the ceiling and the water both.
Get electronics, documents, and anything irreplaceable clear of the water. Anything plugged in below the leak needs unplugging at the wall, not the appliance.
ARI’s emergency line runs 24 hours a day, every day of the year, so a burst pipe at 3am gets the same response as one at 3pm. Every plumber carries £5M public liability insurance and works alongside our electricians, carpenters, and cleaners, so if an emergency crosses trades, one call covers it all. You are not choosing between a fast response and a proper job. With ARI, you get both.
