How much does it cost to run a 1 kw electric fire for 1 hour?
That’s a question many people ask and which we’ll explain below. With these steps, the cost of running any piece of electrical equipment can be worked out.
A. Quick answer:
Up till 2021 it used to be 11 to 21 pence including VAT depending on who supplies your electricity. In 2022 there’s been a huge increase so now it’s more like 25 to 35 pence per kWh depending on your supplier and region you’re in.
A 1kW fire running for one hour uses 1kWh of energy in kilowatt hours. One kWh of energy costs about (say) 30 pence. (Look on your bill for the exact rate you are paying.) **This is why it pays to check what other suppliers charge.
