Calculate exactly what your portable heater costs per hour, session and year.
Portable electric heaters are a common way to heat a single room, but running costs depend on the heater wattage, how long it runs and your electricity unit rate. A 2,000 W heater running for four hours uses 8 kWh — at 26p/kWh that is over £2 per session. Understanding the maths helps you make informed decisions about heating individual rooms.
At the current UK electricity price cap of 26.32p per kWh, a 2kW electric heater costs approximately 52.6p per hour to run. Actual costs vary by heater type, wattage, and how long the thermostat cycles the heater on and off.
