LDZ
Local Distribution Zone
Gas NetworksOne of 13 geographic regions within the gas distribution network, each with its own transportation charge rates.
Local Distribution Zones (LDZs) are the gas equivalent of DNO regions for electricity. Great Britain is divided into 13 LDZs, each operated by one of the 4 GDNs. Gas transportation charges vary by LDZ, similar to how DUoS rates vary by DNO region.
The 13 LDZs:
| LDZ Code | Name | Operator |
|---|---|---|
| EA | East Anglia | Cadent |
| EM | East Midlands | Cadent |
| NE | North East | NGN |
| NO | Northern | NGN |
| NT | North Thames | Cadent |
| NW | North West | Cadent |
| SC | Scotland | SGN |
| SE | South East | SGN |
| SO | Southern | SGN |
| SW | South West | WWU |
| WM | West Midlands | Cadent |
| WN | Wales North | WWU |
| WS | Wales South | WWU |
Important difference from electricity: Unlike electricity MPANs which encode the DNO region in the Distributor ID, gas MPRNs do not encode the LDZ. To determine which LDZ a gas meter belongs to, you must look up the postcode. This is why gas validation often requires the meter's postcode.
Example
A gas meter in Manchester would be in the NW (North West) LDZ, operated by Cadent.Related terms
