A leaking boiler should never be ignored. Water inside or under a boiler can damage internal components, cause it to lose pressure and shut down, and in a gas appliance it needs a qualified, Gas Safe registered engineer to inspect it safely.
Common causes are a failed pressure relief valve, corroded internal pipework, a faulty pump seal, or too much pressure in the system. We’ll find the source, isolate it, and make a safe repair.
If you smell gas at any time, leave it to the experts: open windows, don’t touch electrical switches, and call the National Gas Emergency line on 0800 111 999 first — then call us. For boiler leaks and breakdowns across the TW area, we’re available around the clock.
What to do right now
- Turn the boiler off at the switch and turn off the water supply to it if you can.
- Place a container under the drip and keep the area clear.
- Note any error code and the boiler make and model.
- Call us — do not attempt to open or repair the boiler yourself.
