Electricity
To find out who supplies the electricity to your new home you need to call the NEDL Meter point reference administration service, provide them with the meter number for your property, and they will be able to give you your current electricity supplier and MPAN number (also found at the top of any bills as the supply number – this is different from your account number). The same applies as with setting up a gas account from this point.
