Question: how much does it cost to run your central heating for an hour?
Answer: Sounds simple right? In UK, based on the data of British Gas for electricity rate by unit (kWt), it cost around 13 pence per kWh unit. This means that if your heater consumes around 2000 watts (2 kWt), your bill would be 2 kWt x 13 pence per hour.
