Boiler / heating issue
No heat, no hot water, low pressure, or a boiler showing a fault code.
Quick things to check first
- 1Check the boiler pressure gauge is in the normal range.
- 2Note any fault code or light shown on the display.
- 3Check radiators for cold spots, which can mean they need bleeding.
These are general pointers, not a full diagnosis. For guidance tailored to your exact problem, show us a photo and describe it.
When to call a professional instead
- Any smell of gas — leave the property and call your gas supplier's emergency line immediately
- A fault code you can't resolve by repressurising
