Local distribution zones (LDZ)

Twelve zones in the UK managed by four distribution network operators. The National Grid has divided the UK into LDZs for the purpose of calculating shippers’ charges for transporting gas within the National Transmission System (NTS). Gas is delivered to the local distribution zones via the NTS, which then supply the end-user. This is achieved via a less pressurised system than the NTS.
