Emergency Boiler Repair: When to Call
Some boiler faults can wait; others — no heat in winter, leaks, gas smells — can't.
Knowing which boiler problems are true emergencies helps you act fast when it matters and avoid panic when it doesn't.
Call immediately
No heat or hot water in freezing weather (especially with vulnerable residents), significant leaks, a gas smell, or a sounding CO alarm all warrant emergency response.
Can usually wait
Minor pressure top-ups, a single radiator cold spot, or a non-urgent noise can typically wait for a scheduled visit — but still get them checked.
