Understanding your UK electricity bill: what makes up the cost of 1 kWh?

When you look at your electricity bill, the cost isn’t just a flat fee. It’s a combination of several factors, primarily the unit rate and the standing charge. The unit rate is the price you pay for each kWh of electricity you consume. Think of it as the price tag for every unit of energy your appliances use.

Alongside the unit rate, you’ll also see a standing charge1. This is a fixed daily fee that covers the cost of supplying electricity to your home, regardless of how much energy you use. It helps maintain the grid and other essential services. Finally, Value Added Tax (VAT) is applied to your energy costs. For domestic electricity, VAT is charged at 5% and is already included in the unit rates and standing charges you see from your supplier.

Key factors influencing your electricity cost per kWh
