Find Your Business Electricity DNO


Who is my business energy supplier?

The UK’s Distributor Network Operator (DNO) system is divided between 14 companies, 6 of which manage multiple areas’ electricity supply, and 8 independent DNOs. Ofgem monitors all DNOs to prevent monopolisation and ensure business energy customers are treated fairly. Each DNO is responsible for supplying electricity to consumers in their area.

If you’re uncertain about who supplies your business energy, check out our table below to find out which Distributor Network Operator (DNO) manages your electricity and see how to get in contact with them.

You will be able to identify which DNO supplies your business electricity using the Distribution ID found on your MPAN.

Your MPAN can be found on a recent electricity bill from your supplier. However, if it is not visible, get in contact with your energy supplier and they will provide your business’s Distribution ID.

"After Scottish Power changed our business rates half way through the contract we were in set up by Switch My Business, we spoke to Natalja and she helped us sort this issue. Unfortunately, Scottish Power wouldn't play ball and were not agreeing to let us out the contract. Natalja worked extremely hard to sort this out for us and even put a claim in with them for the out of contract rates they put us on as one advisor at Scottish Power said they would refund the difference then another said they would not, along with plenty of other issues and broken promises along the way. It was a long and pretty painful process but Natalja did not give up and we have won the claim against Scottish Power. Very happy with the service Natalja provided."
