How to load-shift with a heat pump: cut your electricity bill by £200–£400 a year

Time-of-use tariffs offer rates as low as 14–17p/kWh during off-peak windows — roughly half the standard cap rate of 24.7p. But you only capture those savings if your heat pump actually runs during the cheap hours. Load-shifting moves your heating and hot water consumption into those windows. Done well, it's worth £200–£400 a year on the right tariff. This guide explains how to do it, what controls you need, and what’s realistic without it becoming a hobby.

Heat pump hot water: when to heat your cylinder (and when not to)

Hot water is the easiest load to shift on a time-of-use tariff — and the most valuable. A 200-litre cylinder reheated during a cheap window at 14p/kWh instead of the 24.7p standard rate saves the cost difference on every single litre, every single day. This guide covers how heat pump hot water works differently from a boiler, why timing matters, and how to set a schedule that captures the saving without ever running out of hot water.
