What to expect when you call
- Advice on the phone: We ask what the boiler is doing, note any fault code and talk you through simple, safe checks, like the pressure gauge and thermostat, that sometimes get the heating back on straight away.
- Diagnosis on site: Our engineer tests the boiler, controls and system to find the real cause, then gives you a fixed price before carrying out any work.
- Making it safe: We fix the fault on the first visit where we can. If a part needs ordering, we make the system safe and explain exactly what happens next.
Stay safe while you wait
If you smell gas, turn off the supply at the meter, open the windows, avoid using electrical switches and call the National Gas Emergency Service on 0800 111 999 before anything else. For a leaking boiler or radiator, switch the boiler off at the mains and turn off the water at the stopcock to limit the damage. Many breakdowns can be avoided with a yearly boiler service, so once your heating is working again it is worth booking one.
