Ask the letting agent, landlord, or previous tenant/owner

If you've just moved into a new property and are unsure who your electricity supplier is, the simplest way to find out is to ask the letting agent, landlord, or the previous tenant or owner of your property. If the previous occupant has informed the electricity supplier of their departure, the supplier will likely send you a letter addressed to 'The Occupier', which should include any details you need about your electricity supplier.

If you've already been living in your property for a while, or if the previous tenant hasn't informed their electricity supplier that they're moving out, you may need to take additional steps to identify your supplier. One option is to contact your local electricity distribution company and the Meter Number Helpline.

Additionally, if you own your home, you could ask the previous owners or the estate agent for this information. They may have records of the previous electricity supplier or be able to direct you to the relevant resources or people to find out.

It is important to identify your electricity supplier to ensure you are on the best tariff for your usage needs and to know who to contact in case of any issues.

Check your energy bill

If you're unsure about your energy supplier, you can find out by checking your latest energy bill, which will have the electricity provider's name and their contact details. Energy bills can be sent to your home address or email inbox, so be sure to check both. If you've moved into a new house, you can ask the landlord or real estate agent for help.

Energy bills contain a 'Distributor ID' number, which can help you find your electricity network operator. Your network operator is different from your energy supplier, as they own and operate the cables in your area. They maintain the wires that bring electricity to your home and fix power cuts that are not caused by problems inside your home.

Your energy bill will also have your Meter Point Administration Number (MPAN), which is like a unique ID for your electricity supply. It helps energy companies keep track of your electricity usage and send the correct bills to the right people.

If you can't find a bill, you may be signed up to a digital bill-only plan, so check your emails. If you can't find an old bill and have no contact with previous bill-payers, you can contact your electricity distribution network or network operator, who can then provide your supplier's details.

Contact your energy network operator

If you are unsure who your electricity supplier is, you can contact your energy network operator to find out. Your energy network operator is different from your energy supplier. The former connects your home to electricity, moves your electricity meter, and fixes power cuts that are not caused by issues inside your home.

To find your electricity network operator, you can use the Energy Networks Association (ENA) search tool. Simply enter your postcode, and you will be able to find out which network operator looks after your connection. Alternatively, you can call 105 for free if you live in England, Scotland, or Wales, and you will be connected to your distribution network operator.

Call your local electricity distribution company

If you've been living in your property for a while and haven't received such a letter, or if the previous tenant didn't inform their supplier, you may need to call your local electricity distribution company. Your electricity distribution company is different from your energy supplier, which is the company that bills you for your energy usage. Your electricity distribution company helps connect your home to electricity, moves your electricity meter, and fixes power cuts that aren't caused by issues inside your home.

Use the Find My Supplier service

In some cases, the previous occupant may have informed the energy firm of their move, prompting the current supplier to send a letter addressed to "The Occupier" with relevant information about your electricity supply. If you have already been living in the property for a while and have not received such a letter, you may need to contact your local electricity distribution company or the Meter Number Helpline to identify your electricity supplier.

It is important to know your electricity supplier to ensure you are not overcharged and to facilitate a smooth transition when switching suppliers or tariffs.
