Future UK Link Releases

There will be three major UK Link Releases every year. Major Releases take place in:

  • February to March
  • June to July
  • November to December

The first three releases were named: Release 1; Release 2 and Release 3. From the fourth release, the naming convention was changed. To make things easier and more meaningful, release names will now reflect the month and year of the scheduled implementation.

The next release is Minor Release Drop 9 2019 Release. Information on this Release can be found here.

The November 2019 Release was successfully implemented on Friday 8th November 2019.

As new releases come online, relevant details and links will be added here.

Programme Background

We deliver managed change to ensure our systems:

  • deliver customer requirements
  • respond effectively to industry needs
  • maintain infrastructure integrity and stability

The UK Link Programme and now UK Link Releases represent one of the largest of these changes.

Extensive industry discussions agreed the original requirements before the launch of the Programme. The Business Requirement Documents can be viewed on the Joint Office of Gas Transporters website.


The changes and upgrades represented one of the most significant changes to the gas industry with existing processes amended, new processes introduced and a raft of other enhancements, including functionality for:

  • receiving and storing greater volumes of meter readings
  • greater flexibility for system enhancements and reporting
  • using smart meter information to help consumers switch

The newly launched UK Link system also saw the entry route changed, with all Users accessing the system through the Xoserve Services Portal.


The new system went live in June 2017, using a SAP solution.

The programme was led by us with the help and support of numerous business partners, including:
