We are becoming a separate company

In April 2019, Electricity Transmission is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Breaking down your bill

Energy bills can sometimes seem complex. Different elements make up the total amount you have to pay, which includes the costs of a number of companies: generators, the transmission owner, the distribution network operator and the supplier.  

Breaking down your 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. This transmission network cost is currently £25 per average annual household fuel bill – that’s around 4.5% of your total bill – less than a tank of petrol or a family trip to the cinema.

The other costs in your electricity bill include: 

  • wholesale costs — which are the biggest part of your bill, covering how much your supplier has to pay for the electricity that they supply you with
  • other providers’ network costs — which cover the running of the electricity distribution network
  • operating costs — which cover the running of a retail energy company, metering operations, building rents and providing customer service 
  • Environmental and social policy costs — which pay for things like programmes to ensure the security of energy supply, delivering lower carbon electricity, and providing energy-efficient homes. They also go towards direct financial support for the fuel poor.
