When switching your energy supplier there are two golden supplier numbers needed to ensure that the right meter is switched. Especially in cities, MPAN and MPRN numbers are needed to make sure your neighbour's energy supply is not converted.

How do you find your MPAN (electricity supplier number)?

Option 1: Your MPAN should be on your energy bill, often located towards the end or on the back. It looks like the number below.

Option 2: Enter your address into the UK Power Networks website to check the national database.

Option 3: Not in the national database? Call the National Grid on 0870 608 1524 to get them to check why you're not featuring in the national database.

Your MPRN has a less distinctive look and is typically a 10 string number as noted below.

How do you find your MPRN (gas supplier number)?

Option 1: Your MPRN should be on your energy bill, often located towards the end or on the back, but often before your MPAN. It looks like the number below.

Option 2: Call the National Grid on 08706081524 to get them to check the national database.

What do MPAN and MPRN stand for?

MPAN stands for metering point administration number. It is sometimes also referred to as supply number or S number.

MPRN stands for meter point reference number. It is sometimes also referred to as M number.

Switchd was launched in February 2017 with the aim of saving Britain millions of pounds off its annual energy bill. Unlike comparison sites, the service automatically handles the switching process from start to finish, using an algorithm to constantly scan for the best energy deal tailored to your preferences and usage data. Subscription is free or starts from £1.99 a month, and Switchd guarantees to save each household at least £50 off its annual energy bill before it takes a payment.
