Off-peak supply specialists

Economy 7 heating fault diagnosis

If several heaters or the lower cylinder element fail together, the problem may be the off-peak supply rather than every appliance. We follow the circuit and identify where power stops.

Find out why overnight heating or hot water has stopped

Boost works but overnight heating does not

This symptom helps separate the continuously available supply from the off-peak charging arrangement. Tell us whether the problem affects heaters, the cylinder or both, and whether your meter or tariff has recently changed.

What we can investigate

We test the accessible customer-side circuits, timers, contactors and appliance supplies. If the findings point to supplier-controlled metering or switching, we explain what needs to be raised with your electricity supplier.

Useful information before attendance

Have your tariff name, advertised off-peak times and appliance details available. Actual switching arrangements vary, so we do not assume all properties receive the same hours or that every fault can be observed during a daytime appointment.

Common questions

Useful answers

Can you test Economy 7 during the day?

Many checks can be completed safely during the day, although a timed or supplier-controlled fault may require confirmation when the off-peak supply operates.

Is the meter always the cause?

No. The fault may be in the meter switching, contactor, consumer unit, circuit or appliance, so systematic testing matters.
