A boiler that will not fire, or fires but gives you no hot water or heating, usually comes down to a small set of faults: low pressure, a tripped electrical supply, a faulty thermostat, a frozen condensate pipe in winter, or a safety lockout. Some checks are safe to do yourself; anything inside the appliance needs a Gas Safe registered engineer.
Enter your postcode and EmergencyLines finds the nearest available engineer with genuine emergency cover. You speak to the engineer directly, explain what the boiler is doing, and agree timing and price before they travel. There is no dispatcher and it is free to check who is available.
Before calling, check that the pressure gauge reads around 1 to 1.5 bar, the gas and power are on, and the thermostat is calling for heat. In cold weather, look for a frozen condensate pipe outside and note any fault code on the display. Those details help the engineer arrive prepared.
Do not remove the boiler casing. Check only the controls and supplies you can reach safely, then stop if the boiler repeatedly locks out:
Common causes include low pressure, a tripped power supply, a faulty thermostat, a frozen condensate pipe or a safety lockout. Note any fault code shown so a Gas Safe engineer can identify the cause quickly.
That often points to a diverter valve or another specific component rather than the entire boiler. Tell the engineer exactly what still works so they arrive prepared.
