Electricity
If you run a heat pump, electric boiler or storage heaters, the right tariff matters more than the right appliance. Time-of-use tariffs can cut heating costs by a third if you can shift usage — and they pair beautifully with a hot-water cylinder or home battery.

Three tips from the electricity desk
Match the tariff to the appliance
A heat pump running 16 hours a day needs a heat-pump tariff, not Economy 7. Mismatched tariffs can add £300/year to running costs.
Use a timer, even without smart kit
A £15 plug-in timer on an immersion heater can shift 80% of hot-water heating into cheap hours. Payback: about six weeks.
Check if you qualify for the Warm Home Discount
Electric-heated homes on certain benefits get £150 off the winter bill automatically. Ensure your supplier has you flagged.
