Electric radiators, panel heaters and oil-filled models provide zoned, controllable heat for homes or rooms without gas central heating. The best have accurate thermostats and timers to avoid wasted energy.
Why electric radiators matter
Electric heating costs more per kWh than gas, so control is everything. A well-chosen radiator with a precise thermostat and schedule heats only when needed, keeping electric heating bills manageable.

Prioritise accurate thermostats
Cheap heaters overshoot and waste energy — precise, programmable control is worth paying for.

Consider off-peak tariffs
Pair with Economy 7 or a smart tariff where possible to cut the cost per unit.
