You asked

I would like to receive details of any planning work that has been carried out to understand the possible impact of Brexit on IT systems operated by or behalf of the Office for National Statistics, including any relevant arms-length bodies.

Planning work could include internal investigations, seeking advice from other government bodies, external consultancy, systems testing or development.

By 'impact' I mean modifications to existing IT systems, and/or development of new systems, required to enact any changes to government policy that might result from Britain’s departure from the EU.

Please could you let me have:

  1. Details of any such planning work carried out to date, and which IT system(s) it relates to.
  2. Any advice the organisation has received, as a result of this planning work, about actions it may need to take to ensure its IT systems are ready for Brexit, including estimated costs if available.
  3. An indication of whether the organisation has already undertaken these actions, is planning to undertake them, or is considering them pending further information.

Thank you for your recent request.

No work of the kind detailed has been commissioned to-date as a result of Brexit.

The need for such work will be considered as and when requirements are identified in the course of Brexit planning.
