A plumbing emergency can cause thousands of pounds of damage in hours. A burst pipe left for even 30 minutes can saturate floors, soak through ceilings, and damage electrics. Speed is everything — which is why our 24/7 emergency line is answered directly by our team, not a call centre.
We cover all emergency types: burst and frozen pipes, major leaks from radiators, boiler breakdowns, loss of heating and hot water, blocked drains causing sewage backup, overflowing cisterns, failed appliance connections, and suspected gas escapes (where we work alongside National Gas Emergency).
When you call, we take brief details of the emergency, advise you on immediate steps to take (isolating water supplies, shutting off gas), confirm the call-out rate, and dispatch the nearest available Gas Safe engineer. We keep you updated with an accurate ETA — no vague arrival windows.
All emergency work carries our 12-month workmanship guarantee on labour. We use quality parts from reputable suppliers and never carry out unnecessary work to inflate a bill. Emergency call-outs get the same quality of work and customer care as any other job — just faster.
