Understanding Electricity Costs

Electricity is billed in kilowatt-hours (kWh). One kWh is the energy used by a 1,000W appliance running for one hour. To find your cost: multiply the wattage by hours of use, divide by 1,000 to get kWh, then multiply by your tariff rate.

The UK energy price cap for Q2 2025 sets the unit rate at around 28p/kWh. Your actual rate depends on your tariff and supplier. Check your bill for the exact figure.
