Electricity Distributors

The companies that own the physical networks that carry our electricity

Following deregulation over the last 10 years the market place remains geographically split into 14 Public Electricity Supply Areas (See Fig. 1) which are run by 7 different Distribution Network Operators.

In 1990 the Area Electricity Boards were replaced by Regional Electricity Companies, which were then privatised. The DNOs are the successors to the distribution arms of the RECs.

• These areas reflect the boundaries of the old electricity boards prior to deregulation. However, there are now over 20 different supply companies to choose from and most also offer gas supplies as well.
• In each area the DNO has a monopoly on distributing electricity from the grid to homes and businesses.
• They are NOT allowed to supply electricity. This must be done by a separate company of the consumer’s choice, who make use of the distribution network.
• The cost of distribution is built in to the price of your electricity, meaning that in areas that require more pipes and more maintenance, like Scotland, the price of electricity and standing charges are generally higher than they would be in London, for example.
• You may need to contact your distributor in case of arranging a new electricity connection or reporting a problem with your supply.

Finding out which distribution zone you are in

You can find your area ID on your bill – it is the first 2 digits of the bottom line of your MPAN. You can see the area IDs on the map below:
