Read articleNot sure who supplies your business electricity or gas? How to find your supplier by postcode, read your MPAN and MPRN, and what to do if you have just moved in.

Knowing who supplies your business energy is the first step to cutting your bills. You need it to read your contract, check your end date and compare deals. If you have just moved premises, it also stops you paying expensive deemed rates for longer than necessary.
Here is how to find your business electricity and gas supplier in a few minutes.
The quickest way is usually the paperwork you already have. Look for:
Your bill also shows your contract end date, the most useful detail when you come to compare.
Electricity in Great Britain is delivered by regional distribution network operators. They do not sell energy, but they hold records of which supplier is registered to each meter.
It helps to have your MPAN (Meter Point Administration Number). It is on your electricity bill, often in a box starting with S. The bottom line is the 13 digit core number that identifies your supply.
For gas, use the Find My Supplier service and search by postcode. You can also call the Meter Number Helpline on 0870 608 1524, Monday to Friday. Calls are charged, so check the cost with your phone provider.
Ask for your MPRN (Meter Point Reference Number) while you are there. You will need it to get gas quotes.
| Electricity | Gas | |
|---|---|---|
| Meter number | MPAN | MPRN |
| Where to find it | Your bill, in a box often starting with S | Your bill, usually 6 to 10 digits |
| How to look it up | Your local network operator | Find My Supplier or the Meter Number Helpline |
When you take over a property, you are automatically supplied by whoever supplied the previous occupier, usually on deemed rates. These are among the most expensive rates a supplier charges.

Water works differently. In England and Scotland your bill comes from a water retailer, while your regional water company runs the pipes. Your retailer’s name is on your water bill. See our guides to business water rates and business water in Scotland.

Check a recent bill first. If you have none, find your local network operator on the Energy Networks Association website and use its postcode search, or contact the operator, to find the supplier registered to your meter.
Search your postcode on the Find My Supplier website, or call the Meter Number Helpline on 0870 608 1524. You can also ask for your Meter Point Reference Number (MPRN).
The Meter Point Administration Number is the unique number for your electricity supply. It is shown on your bill, often in a box starting with S, and the bottom line is 13 digits long.
The Meter Point Reference Number is the unique number for your gas supply. It is usually 6 to 10 digits and appears on your gas bill.
You will be on the existing supplier's deemed rates from the day you start using energy. These are usually expensive, so contact the supplier, take meter readings and compare deals straight away.
Yes. Once you know your supplier, ask them for your end date. A broker can also find it for you when you request a quote.
