Emergency Plumber
London& Surrounding Area

Any reputable emergency plumber working in London will carry public liability insurance — typically a minimum of £2 million cover. This protects you if the plumber accidentally causes damage to your property during the repair. Always ask to see proof of insurance before work begins, and be wary of any tradesperson who cannot provide it.

Turn off your water supply immediately using the stopcock — usually found under the kitchen sink or where the mains pipe enters your property. Switch off your central heating and any water heaters to prevent further damage. Open all cold taps to drain the remaining water from the system, then call an emergency plumber in London straight away.

If the work involves any gas appliance — boilers, gas fires, gas cookers — then yes, your plumber must be Gas Safe registered by law. It is a criminal offence for anyone not on the Gas Safe Register to carry out gas work. For general plumbing tasks like fixing leaks, unblocking drains or replacing taps, Gas Safe registration is not required but is still a useful indicator of professional standards.

Yes, leaking radiators are a common plumbing repair. The leak is usually from the valve, the bleed point or a corroded joint. A plumber can typically fix a leaking radiator valve in under an hour for £60 to £120. If the radiator body itself is corroded through, it will need replacing — expect £150 to £350 including the cost of a new radiator.

Insulate all exposed pipes in your loft, garage and exterior walls with foam lagging — available for under £10 from any DIY shop. Keep your heating on a low background temperature (at least 12°C) even when you are out, and open loft hatches occasionally to let warm air circulate. If you are leaving the property empty in winter, consider draining the system or asking a neighbour to check daily.

Yes — any reputable plumber will assess the problem and provide a clear quote before beginning work. For emergency call-outs, they will explain the call-out fee upfront and then give a fixed price for the repair once they have diagnosed the issue. Never agree to work without a written or verbal quote, and be cautious of plumbers who refuse to give one.
