Emergency Plumber London — 24hr Call-Out, 1–2 Hour Response

Emergency Plumbing — What It Is and When to Call

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.

Burst Pipes

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.

Major Leaks

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.

No Hot Water or Heating

Boiler failures in cold weather are a same-day emergency, especially with elderly occupants or young children. We diagnose and repair most combi, system, and conventional boilers, with parts in the van for common faults.

Sewage Backup

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 drains →

Toilet Overflow

A 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 toilets →

Frozen and Cracked Pipes

Winter 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.

Stop the Damage Tonight

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.

Know the Price Before the Toolbox Opens

We confirm the cost on arrival, before any work starts. No "we will see when we get there" surprises. Out-of-hours premiums are stated up-front and capped to a clear hourly rate.

Multi-Trade in One Visit

If your emergency involves electrics as well as plumbing — a boiler fault tripping the consumer unit, a washing-machine leak shorting the kitchen ring main — we handle both trades in one visit. No calling a second company at 11pm.

Written Guarantee on Every Fix

12-month workmanship guarantee on every emergency repair. Public liability insured. If the same fault returns inside the warranty window we come back at our cost.

Why London Property Owners Use ARI for Emergencies

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 rated 5.0 stars across 27 Google reviews and 9.94/10 across 32 Checkatrade reviews. 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.
