    What are change packs?

    When we make changes to our infrastructure and services – or lead on industry reform – we publish change packs.

    These documents share information about changes with the industry.

    Often, we ask customers to review the information and send us their responses.

    Different types of change packs

    We publish four types of change packs.

    Initial review – this asks customers and stakeholders for their opinions on new changes.

    Solution review – this outlines different solutions and their costs.

    Design – this has information about a change’s specific design, plus any amendments to file formats and impact on systems.

    Other – this contains changes that are implemented for special or unexpected reasons. These packs can be used for:

    • information
    • general review
    • representation
