Is my gas network the same as my gas supplier?

No. Your Gas Distribution Network (GDN) owns and maintains the pipes that bring gas to your property and is fixed by location. Your supplier is the company you pay and can switch. Four companies run all eight GB gas distribution licence areas between them: Cadent, SGN, Northern Gas Networks and Wales & West Utilities.

Can my gas network be an independent gas transporter instead?

On some newer housing developments, the final pipework is owned by an Independent Gas Transporter (IGT) rather than one of the four main GDNs, though it still connects to the national network. Your MPRN and bill will usually still show a main GDN region; 0800 111 999 still applies for a suspected leak.

Who is my gas network?

Q: What number do I call if I smell gas?

Call 0800 111 999 immediately, the National Gas Emergency Service line. It is the same number everywhere in Great Britain regardless of which of the four GDN companies runs your local network, and it is staffed 24 hours a day.

Four companies run Great Britain's gas pipes across eight licensed regions. Your gas network is fixed by location and cannot be switched — but it's not who you pay. Find your region below.

Unlike electricity, a gas Meter Point Reference Number (MPRN) has no built-in region code — it is a plain 6-to-10-digit number, so postcode area is the most practical way to identify your Gas Distribution Network (GDN).
