Who Is My Gas Supplier?

How this helps your business

To find who supplies your business gas, enter your postcode in the tool above to identify your Gas Distribution Network, then look up the registered supplier on the national Find My Supplier service at findmysupplier.energy using your postcode or MPRN, by calling the Meter Number Helpline on 0870 608 1524, or by checking a recent bill. There is no single free public website that names the supplier from the meter alone, so the quickest accurate answer combines the network lookup above with one of those supplier routes. Need the electricity or water answer too? Start from our who is my supplier hub and pick the utility.

Network operator versus supplier: the distinction that trips businesses up

The Gas Distribution Network (GDN) and your supplier are two different companies, and conflating them is the single most common reason a business calls the wrong number. The GDN owns the physical pipes, runs the gas emergency line, and is fixed by your location: there are four GDNs in Great Britain, Cadent, Northern Gas Networks, SGN, and Wales & West Utilities. You cannot switch your GDN. Your supplier is the company that buys gas wholesale, sends your bill, and is the one you tender. The tool above returns the GDN; the supplier is what you confirm via Find My Supplier or a bill. The same network-versus-billing split applies to electricity, which our electricity and gas network lookup tool maps in full across all 14 distribution regions.

What the MPRN is, and where to find it

An MPRN (Meter Point Reference Number, often called the M number) is the unique 6 to 10 digit code that identifies your gas supply point. It stays the same when you switch supplier, which makes it the most reliable handle for any lookup. It is printed on every gas bill and is searchable by postcode at Find My Supplier. If you do not have a bill to hand, the MPRN finder further down this page walks you through retrieving it, and the Meter Number Helpline on 0870 608 1524 can read it out over the phone.

No bill, just moved in, or out of contract?

If you have just taken on a premises, you are billed by whichever supplier holds the registration, often on expensive deemed rates until you agree a contract. The fastest path is to enter the postcode at Find My Supplier to see the registered supplier and MPRN, then arrange a proper contract before those deemed or out-of-contract rates erode your margin. Knowing your contract end date is what unlocks a better deal: most business gas contracts only allow you to re-tender in a fixed window before they expire, and missing it rolls you onto default rates.

Why businesses ask Purely to confirm it

Finding the supplier is step one. Knowing whether you are paying a fair rate, when you can move, and how to time the wholesale market is where the savings sit. Purely Energy is a B-Corp certified UK business energy and water consultancy that manages 2,000+ sites and more than £100M of annual energy spend for 500+ business clients, with 30+ suppliers on our panel. We retrieve your supplier, MPRN, contract end date and current rate for free via a Letter of Authority, then tender the market on your behalf. Businesses we manage typically save 15 to 30%. We work for you, not the suppliers, with no hidden commissions. When you are ready, you can request a business gas quote or read more on our business gas procurement page.

Multi-site portfolios

If you run several premises, each has its own MPRN and may sit on a different supplier and contract end date, which makes a portfolio tender far more valuable than chasing sites one at a time. We consolidate the registrations, align renewal dates where it helps, and present a single position so your finance team sees the whole estate.
