Xoserve

Xoserve is the Central Data Service Provider (CDSP) for the GB gas industry, performing a similar role to what Elexon does for electricity settlement. They operate the central systems that enable the gas market to function.

Xoserve responsibilities:

• Managing the UK Link system (central gas industry database)
• Processing meter readings and consumption data
• Managing gas supply point registration and switching
• Operating industry data flows between parties
• Maintaining MPRN registration
• Publishing market data and reports

Key systems:

• UK Link - The central gas industry system for registration, settlement, and communication
• Gas Enquiry Service - Lookup tool for MPRN and supply point information
• Gemini - System for daily energy balancing

Who funds Xoserve: Xoserve is funded by the gas transporters (GDNs) and operates as a shared service for the whole industry. Their costs are ultimately recovered through transportation charges.

Why Xoserve matters: To determine information about a gas supply point (LDZ, shipper, AQ, etc.), the authoritative source is Xoserve's UK Link system. Energy suppliers and industry parties query this system to validate supply points and process switches.
