Usually, a modern gas boiler cannot provide normal central heating during a power cut because controls, ignition systems, pumps or fans require electricity.

FREE / NEXT STEP

POWER DEPENDENCY CHECK

Identify which normal household functions depend on mains electricity before an outage forces you to discover them.

RUN THE FREE CHECK

WHAT TO DO WITH THIS

The useful question is not only whether the boiler stops. Check what happens to thermostats, circulation pumps, smart controls and any alternative heat source you rely on.

LIMITS / SAFETY

Never improvise electrical connections or generator back-feeds. If heating is medically important or someone is vulnerable to cold, make a specific contingency and check relevant Priority Services Register eligibility.
