Recommendations (6)
Fund legal advice for HSS claimants before scheme choice
- The Department for Business and Trade broadly accepted this recommendation on 9 October 2025, but stated that funded legal advice would be provided at the appeal permission stage rather than upfront as recommended (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted the government provides funded legal advice at appeal stage rather than upfront as recommended (Business and Trade Select Committee evidence session, January 2026).
- The Business and Trade Committee report HC 1598 concluded the government had not properly implemented this recommendation, finding that legal advice is not available at the point of decision between Fixed Sum Offer and assessed redress (Business and Trade Committee, HC 1598, March 2026).
Set deadline for HSS claims with guidance on late applications
No claims for financial redress under HSS shall be entertained after midnight 27 November 2025.
- The Department for Business and Trade broadly accepted this recommendation on 9 October 2025 and closed the HSS to new claims on 31 January 2026, a later date than specified to allow adequate notice (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Post Office issued reminder letters to outstanding claimants, and DBT published guidance on exceptional cases (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee confirmed the HSS was closed to new claims on 31 January 2026 (Business and Trade Select Committee evidence session, January 2026).
Allow Advisory Board to monitor individual compensation cases
The Horizon Compensation Advisory Board should not be prevented from monitoring individual cases in which compensation has been or is to be determined by paragraph 4 of its Terms of Reference.
- The Horizon Compensation Advisory Board has published quarterly reports on its monitoring activities, including monitoring individual cases (Horizon Compensation Advisory Board published reports, ongoing).
- The Business and Trade Select Committee heard evidence confirming the Advisory Board was performing this monitoring function (Business and Trade Select Committee evidence session, January 2026).
Make monitoring full and fair compensation a core Board duty
It must be one of the core duties of the Horizon Compensation Advisory Board that it monitors whether compensation payments are full and fair.
- The Horizon Compensation Advisory Board continues to monitor whether compensation payments are fair across all schemes (Horizon Compensation Advisory Board published reports, ongoing).
- The Business and Trade Select Committee heard evidence from the Advisory Board on its monitoring activities (Business and Trade Select Committee evidence session, January 2026).
Amend Limitation Act to extend GLO deadline if needed
- The Post Office (Horizon System) Compensation Act 2024 (c. 1) received Royal Assent on 23 January 2024, establishing a statutory framework for the compensation schemes (Post Office (Horizon System) Compensation Act 2024).
- The Business and Trade Select Committee noted the Limitation Act amendment had not been brought forward as a standalone bill as originally recommended (Business and Trade Select Committee evidence session, January 2026).
- The GLO scheme continued operating beyond August 2024 without the specific Limitation Act amendment recommended.
Set agreed closing date for Horizon Shortfall Scheme applications
No applications for compensation to the Horizon Shortfall Scheme shall be entertained after such date as shall be agreed by the Minister, the Department for Business and Trade, the Post Office and the Horizon Compensation Advisory Board.
- The HSS closing date was subsequently set as 31 January 2026, superseding this interim recommendation through the Volume 1 recommendation POH-15 (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
