Respond to recommendations by 10 October 2025
HM Government and/or the Department and where appropriate the Post Office and Fujitsu shall provide written responses to my recommendations by 10 October 2025.
- The Department for Business and Trade published the government response to the Post Office Horizon IT Inquiry report (volume 1) on 9 October 2025, accepting 17 of 18 recommendations (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 published its formal response on this date, meeting the requirement (Business and Trade Select Committee evidence session, January 2026).
Define and publish meaning of full and fair financial redress
- The Department for Business and Trade published a statement on 9 October 2025 explaining that "full and fair" means claimants should receive sums equivalent to civil litigation damages at the top end of the appropriate range, with discretion to depart from established legal principles when fairness demands (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 published this statement defining "full and fair redress" on 9 October 2025 (Business and Trade Select Committee evidence session, January 2026).
Apply full and fair meaning consistently across all schemes
The Post Office, the Department and the Minister shall ensure that all decision makers in HSS, GLOS and OCS/HCRS apply the meaning to be given to the words "full and fair" when assessing the amounts to be awarded to individual claimants.
- The Department for Business and Trade stated on 9 October 2025 that both DBT and the Post Office had agreed to apply this definition, and that it is referenced in respective scheme guidance (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee found that DBT and the Post Office had agreed to the definition and referenced it in scheme guidance (Business and Trade Select Committee evidence session, January 2026).
Allow 3-month window to accept Fixed Sum Offer after assessment
- The Department for Business and Trade accepted this recommendation on 9 October 2025 and implemented it from that date, giving HSS and HCRS claimants three months from receipt of their first detailed offer to revert to the Fixed Sum Offer (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted the three-month window had been implemented from 9 October 2025 (Business and Trade Select Committee evidence session, January 2026).
Appoint senior lawyer to ensure HSS offers are full and fair
- The Department for Business and Trade accepted this recommendation on 9 October 2025 and announced the appointment of Sir Gary Hickinbottom, then Chair of the HCRS Independent Panel, as HSS Senior Lawyer (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- Sir Gary Hickinbottom assumed the role from December 2025 and began reviewing HSS first offers (Progress update, DBT, March 2026).
- The Business and Trade Committee report HC 1598 noted the appointment was made but found the HSS remained "broken" for fully-assessed claims, with assessed offers taking an average of 25 months and major disparities between first offers and final settlements (Business and Trade Committee, HC 1598, March 2026).
Grant appropriate powers to HSS senior lawyer
- The Department for Business and Trade accepted this recommendation on 9 October 2025 and committed to consulting Sir Ross Cranston, the Advisory Board, Dentons, claimants' legal representatives, and the Post Office to determine the appropriate powers (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- Full details on the scope of the role of the Independent Senior Lawyer were subsequently published on GOV.UK (Progress update, DBT, March 2026).
- The Business and Trade Committee report HC 1598 found that despite powers being granted, fully-assessed HSS offers remain routinely undervalued (Business and Trade Committee, HC 1598, March 2026).
Require HSS first offers match Independent Advisory Panel recommendation
In HSS the Post Office shall be obliged to make, and the Department shall be obliged to approve (when necessary) a first offer to a claimant which is no less than the sum recommended by the Independent Advisory Panel.
- The Department for Business and Trade accepted this recommendation on 9 October 2025, confirming that no first offer had ever been made below the sum recommended by the HSS Panel (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee heard that this had been confirmed as existing practice, requiring no retrospective changes (Business and Trade Select Committee evidence session, January 2026).
Allow HSS Fixed Sum acceptors to appeal with independent permission
- The Department for Business and Trade accepted this recommendation on 9 October 2025, stating that Fixed Sum Offer acceptors would have the opportunity to seek permission to appeal through the Independent Reviewer in the HSSA scheme (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted the HSSA appeals mechanism exists and is functioning (Business and Trade Select Committee evidence session, January 2026).
- The Business and Trade Committee report HC 1598 found that the HSSA appeals process had effectively become a necessary second step because HSS offers are routinely undervalued (Business and Trade Committee, HC 1598, March 2026).
Clarify best offer principle in HSSA guidance with examples
- The Department for Business and Trade accepted this recommendation on 9 October 2025 and updated the HSSA guidance to clarify the meaning and intent of the "best offer" principle (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted DBT updated the HSSA guidance as required (Business and Trade Select Committee evidence session, January 2026).
Apply best offer principle equally in GLOS
The "best offer" principle which will apply in HSSA, as explained in response to Recommendation 10, shall be equally applicable in GLOS.
- The Department for Business and Trade accepted this recommendation on 9 October 2025, confirming the "best offer" principle applies equally across GLO, HSSA and HCRS schemes at all panel stages since 12 August 2025 (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Department announced it would implement this change retrospectively, with any postmaster who received a binding second panel award lower than their final DBT offer receiving a top-up payment (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted DBT committed to applying the "best offer" principle retrospectively across all three schemes (Business and Trade Select Committee evidence session, January 2026).
Amend GLOS to allow claimants oral submissions at panel hearings
- The Department for Business and Trade accepted this recommendation on 9 October 2025, confirming that all GLOS claimants already had the right to make oral submissions for up to one hour at independent panel hearings (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted this right was already in effect prior to the recommendation (Business and Trade Select Committee evidence session, January 2026).
Post Office to engage in negotiations during HSSA appeal period
- The Department for Business and Trade accepted this recommendation on 9 October 2025 with a modified implementation: a three-month notification deadline for claimants to indicate intent to appeal, rather than the nine-month period recommended, with the Post Office engaging in good faith meetings and mediation during this period (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee noted the modified implementation (Business and Trade Select Committee evidence session, January 2026).
Clarify whether HCRS and OCS assessment processes differ
- The Department for Business and Trade accepted this recommendation on 9 October 2025, confirming that HCRS applies identical principles to the previous OCS scheme, ensuring no OCS claimant is disadvantaged by the transfer (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee confirmed DBT's statement that HCRS applies identical principles to OCS (Business and Trade Select Committee evidence session, January 2026).
Devise redress process for affected family members
- The Department for Business and Trade accepted this recommendation on 9 October 2025, committing to establishing a new redress scheme for postmasters' close family members who suffered serious personal injuries including mental injuries (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Select Committee heard evidence on progress towards establishing the family redress scheme (Business and Trade Select Committee evidence session, January 2026).
- The Business and Trade Committee report HC 1598 welcomed the creation of a family redress scheme but urged the government to broaden the definition of "close family member" beyond spouses and children (Business and Trade Committee, HC 1598, March 2026).
- No published details of the scheme design, eligibility criteria, or launch date have been identified as of March 2026.
Publish restorative justice programme by 31 October 2025
- The Department for Business and Trade accepted this recommendation on 9 October 2025, stating that DBT, the Post Office and Fujitsu had jointly embarked on a postmaster-led restorative justice programme facilitated by the Restorative Justice Council (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- Phase 1 sessions were held in September–October 2025 in Belfast, Glasgow, Cardiff and London (Government response to the Post Office Horizon IT Inquiry report (volume 1), DBT, 9 October 2025).
- The Business and Trade Committee report HC 1598 found that Fujitsu had acknowledged moral responsibility but had made no interim payment and agreed no figure towards the approximately £2 billion total redress cost (Business and Trade Committee, HC 1598, March 2026).
Publish Advisory Board meeting reports within 21 days
The Horizon Compensation Advisory Board shall produce written reports in respect of each of their meetings in relation to each of the 3 schemes and publish the same within 21 days of the date of each meeting.
- The Horizon Compensation Advisory Board has published written reports for each of its meetings since this recommendation was made, available on GOV.UK (Horizon Compensation Advisory Board published reports, ongoing).
Increase Advisory Board membership if needed for capacity
If the Horizon Compensation Advisory Board considers it necessary, the number of persons appointed to the Board should be increased so as to ensure that the Board has sufficient capacity to perform the functions set out above.
- The Horizon Compensation Advisory Board had not required expansion as of January 2026, and DBT confirmed it would keep the case under review (Horizon Compensation Advisory Board, January 2026).
Seek court directions for GLO compensation in bankruptcy cases
- DBT successfully applied to court for the required direction, enabling GLO scheme claimants to participate in the compensation scheme (Horizon Compensation Advisory Board, January 2026).
Publish proposals for equal tax treatment of compensation payments
- The Post Office Horizon Compensation and Infected Blood Interim Compensation Payment Schemes (Tax Exemptions and Relief) Regulations 2023 (SI 2023/184) provided the statutory basis for tax exemptions (SI 2023/184, 2023).
- The Post Office Horizon Shortfall Scheme and Group Litigation Order Compensation Payments (Inheritance Tax Relief) Regulations 2023 (SI 2023/1009) provided Inheritance Tax relief for compensation payments (SI 2023/1009, 2023).
