Quick checks to do first
Before calling an engineer, there are a few safe checks that can help identify simple causes:
- Check the boiler has power (switch, fuse, and any isolator)
- Check boiler pressure (often needs ~1.0–1.5 bar cold)
- Check the thermostat is on and calling for heat
- Look for an error code on the boiler display
- If it’s freezing outside, check for a frozen condensate pipe
Common causes
“No heating, no hot water” usually points to a boiler lockout or a control/supply issue:
- Low boiler pressure
- Ignition fault / flame failure
- Frozen condensate pipe
- Faulty thermostat, programmer, or zone controls
- Gas supply interruption (check other gas appliances)
When it’s urgent
If vulnerable people are in the home, the property is very cold, or you have signs of a leak, book urgent help. If you smell gas, leave the property and contact the emergency gas number immediately.
