Make sure that you leave yourself sufficient time to gather the key information before making your preference, as follows:
- Confirm the termination conditions of the contract you have with your current supplier.
- Gather some key information regarding your premises such as the supply number for Electricity Supply S - Number (also referred to as Meter Point Administration Number or MPAN for short).
- Meter Point Reference Number (MPRN for short) for gas together with your company name and address. All of this will be available from your current invoices.
