GDN
Gas Distribution Network
Gas NetworksOne of the four regional companies that own and operate the gas pipes delivering gas from the National Transmission System to homes and businesses.
Great Britain has 4 Gas Distribution Networks (GDNs), which are the gas equivalent of electricity DNOs. Each GDN operates one or more Local Distribution Zones (LDZs) and is responsible for maintaining the gas pipes, responding to gas leaks (call 0800 111 999), and connecting new supplies.
The 4 GDNs:
| GDN | LDZs Operated | Coverage |
|---|---|---|
| Cadent | EA, EM, NT, NW, WM | East Anglia, East Midlands, North Thames, North West, West Midlands |
| Northern Gas Networks (NGN) | NE, NO | Northern England, Yorkshire |
| SGN | SC, SE, SO | Scotland, South East, Southern |
| Wales & West Utilities (WWU) | SW, WN, WS | South West, Wales North, Wales South |
Unlike electricity (where you cannot choose your DNO), your GDN is determined by your location. The GDN charges gas transportation charges that appear on your gas bill, similar to how DNOs charge DUoS for electricity.
Key difference from electricity: The MPRN (gas meter number) does not encode the region like an MPAN does for electricity. To determine which GDN serves a gas meter, you need to look up the postcode.
