Knowing who your gas supplier is matters for paying bills, making account enquiries, submitting meter readings, and for making changes such as switching to a cheaper tariff. In the UK's liberalised energy market, households can choose from multiple competing gas suppliers.

Check Your Bills

The simplest way to find your gas supplier is to look at a recent energy bill. Your gas bill or combined gas and electricity bill shows the supplier's name, logo, and contact details prominently. If you receive paperless bills, check your email inbox for statements from your supplier or log in to your online energy account.

The Meter Number Portal

If you cannot find a bill, the easiest way to identify your gas supplier is to use the Meter Number Portal, accessible at findmysupplier.energy or by calling 0870 608 1524. You enter your gas meter's unique identification number, known as the MPRN (Meter Point Reference Number), which is printed on the meter itself, and the portal returns the name of the registered supplier for that meter. The MPRN is different from the meter serial number; it is a national unique reference for the gas supply point.

If You Have Just Moved In

When you move into a property, you inherit the previous occupant's gas supplier until you arrange to switch or take over the existing account. The previous supplier will bill you for energy used from the date of your move, based on meter readings taken at or around that date. Contact the supplier whose details are on the meter or the most recent bill found in the property to set up an account in your name. You can then switch to a different supplier if you find a better tariff elsewhere.

Emergency Gas Supply

If you suspect a gas leak or have an emergency involving your gas supply, you do not need to know your supplier to get help. Call the National Gas Emergency Service on 0800 111 999, which is the emergency line for the gas network itself regardless of who supplies your gas. This is the number to call for gas escapes and emergency situations.

Summary

Your gas supplier is shown on your energy bill. The Meter Number Portal at findmysupplier.energy identifies your supplier from your MPRN number if no bill is available. New occupants inherit the previous supplier and should contact them to set up an account before switching. For gas emergencies, call 0800 111 999 regardless of who your supplier is.
