Breaking down your bill

Energy bills can sometimes seem complex, and it’s not always clear what consumers are paying for. Here, you can find out how much of your bill goes towards our Electricity Transmission costs, and how that cost breaks down.     

Breaking down your electricity bill

The Electricity Transmission part of your bill, which is subject to regulatory approval, covers the cost of the network’s infrastructure and maintaining it. Our transmission network cost in 2017 was £25 of the average annual household bill of £554 – that’s around 4.5% of your total annual bill – less than a tank of petrol or a family trip to the cinema.
