Who this is for:Members of the Government Statistical Service


The Code of Practice for Statistics emphasises that official statistics should support society’s information needs. Statistics have public value when they are useful, easy to access, remain relevant and support understanding of important issues. Producers of statistics should have a good understanding of how their statistics are being used and regularly review their relevance and usefulness through appropriate user engagement activities. You should consider revising, stopping or replacing statistical outputs whenever it is appropriate to do so to maintain public value.

Changes to official statistics and cessations of statistical outputs should never be a surprise to users. The Head of Profession for Statistics or Lead Official, or the Chief Statistician in devolved administrations, is responsible for deciding who to notify and when or whether to do so if official statistics are to change in scope or if a statistical series will cease.

What the Code of Practice says

The Code of Practice for Statistics discusses these issues under Principle V1 – Relevance to Users, Principle V2 – Accessibility and Principle V3 – Innovation and improvement.

V1 Relevance to users

Producers should maintain a sound understanding of how statistics are used, review user satisfaction regularly and maintain an open dialogue with users, making use of all appropriate channels and using proactive, formal and informal engagement to ensure that user views are considered. Practices V1.1 through to V1.6 are key here. Cessation of outputs, in particular, should be carried out with the full knowledge of users and their views should be taken into account when stopping a statistical series.

V2 Accessibility

Practice V2.6 emphasises that statistics should continue to be publicly available and should be archived as required by relevant legislation. You should consider whether historical back series should be maintained even if a statistical series will not have future releases, and support users in transitioning to new statistical series and understanding differences between old and new outputs if an existing series is discontinued and replaced.

V4 Innovation and improvement

The code encourages producers to improve and enhance statistical outputs, but emphasises the need to involve users in ongoing development so that the statistics remain relevant and useful. Practices V 4.1 through V4.7 are relevant here. The Government Statistical Service guidance on publishing official statistics in development may also be helpful.

Formal consultations

Departmental statisticians may decide to carry out a consultation to understand user views about proposed changes, revisions or new outputs.

Formal consultations should be:

  • informed:
    • relevant central guidance on how consultations should be conducted should be used
    • the views of user groups on the best means of obtaining views should be sought
  • efficient:
    • the importance of the issue and the likely impact of users’ views against the time and resources available should be balanced so as to obtain good value for money from the consultation process
    • duplication of effort should be avoided by liaising and co-ordinating with other producers
    • different methods of consultation should be exploited
  • clear:
    • the consultation should be described and the issues expressed as simply and concisely as possible
    • the timetable for each consultation should be published
  • responsive:
    • records of decisions and actions following a consultation should be published, together with explanations for them
    • individual responses should be published, unless anonymity is requested

Notifying the United Kingdom Statistics Authority about changes or cessations

Change is a normal part of the process of producing and publishing official statistics, so it is not normally necessary to consult with the United Kingdom Statistics Authority or National Statistician about proposed alterations. There are some circumstances (for example where external pressure means that a statistical series is at risk regardless of the impact on public value, trustworthiness or quality) where such notification would be appropriate. The Head of Profession, Lead Official or Chief Statistician in a devolved administration must be informed in such cases, and would normally decide what action to take.

Consider the impact of the change, and whether this is sufficient to require escalation. This is a matter of judgement – if the statistics in question were numbers of high national value then if there was a proposal to cease production rapidly or change them substantially in scope (for example due to resource reduction or instruction from a Minister) there would be a strong case for bringing this urgently to the attention of the Office for Statistics Regulation and the National Statistician. If, on the other hand, the numbers in question were for a specialist audience who were aware of and supportive of the proposals, this would be much less of an issue.

Help and advice

For advice on specific cases, you can contact the GSS Help team at You can ask us about the best approach with regard to any potential changes of scope or cessation. As a rule of thumb, if you have concerns about proposed changes, please notify us or the Office for Statistics Regulation so that we can support you appropriately.

The Office for Statistics Regulation have also published guidance on changes to statistics due to the coronavirus (COVID-19) pandemic which you might find useful.
