Emergency Plumbing FAQs
Everything you need to know about our emergency plumbing, heating and gas services — from response times to pricing.
What counts as a plumbing emergency?
A plumbing emergency is any situation where water is causing active damage to your property, or where you've lost essential water or heating services. This includes burst pipes, major leaks, blocked toilets (if it's your only toilet), no heating or hot water in cold weather, overflowing water, and any gas smell. If water is damaging your home or you're without heating in winter, that's an emergency — call us immediately.

Are your gas engineers Gas Safe registered?

What should I do while waiting for the emergency plumber?
If you have a burst pipe or active leak, turn off your water at the main stopcock immediately — this is usually under the kitchen sink, in an airing cupboard, or near the front door. For heating problems, check your boiler pressure and thermostat settings. For gas smells, call 0800 111 999 (National Gas Emergency Service) immediately, open windows and doors, and do not operate electrical switches.
