Note: On 10 January 2024, Prime Minister Rishi Sunak made a statement to the House of Commons: Government to quash wrongful Post Office convictions – GOV.UK ( We await further details following the Government’s statement.


UPDATE – 13 March 2024: Government announces legislation to automatically quash convictions relating to the Post Office Horizon Scandal. Find out more information at


What has become known as the ‘Horizon Scandal’ took place over many years. It primarily concerns the reliability of previous versions of the Horizon computer system used in Post Offices branches, as well as issues related to previous contracts between Post Office and Postmasters.

A dispute between Post Office and a group of former Postmasters culminated in civil litigation at the High Court, which concluded after a jointly agreed settlement in 2019. There were two main Judgments during the litigation:  The Common Issues Judgment and the Horizon Issues Judgment.

Following the civil litigation, appeals of criminal cases in which Post Office had acted as prosecutor began through the criminal courts.

An independent public inquiry into the Horizon IT scandal was established in September 2020. Following a request from its Chair, Sir Wyn Williams, it became a statutory inquiry in June 2021. Post Office is fully participating to assist its work. The Inquiry’s website with further information can be found here:  Homepage | Post Office Horizon IT Inquiry (


Following the end of the Group Litigation, Appeals of cases in which Post Office acted as prosecutor began, in 2020, with referrals by the Criminal Cases Review Commission (CCRC). The appeals involve convictions for offences such as false accounting and theft.

As part of an extensive post-conviction disclosure exercise Post Office has identified a total of 700 convictions in cases it prosecuted between 1999 and 2015 in which Horizon computer evidence might have featured (in some cases alongside other evidence).  Post Office ceased private prosecutions related to Horizon in 2015.  


Post Office has contacted the majority of the people who were convicted in these cases, although there remain 25 people that it has not been able to trace despite continuing strenuous efforts to do so.  The CCRC has also, separately, contacted people.

You can find the progress of appeals and compensation for overturned convictions on the Post Office’s website


The Post Office’s post-conviction disclosure exercise (PCDE), by external criminal law specialists Peters & Peters, was established in January 2020. Around 4.5 million documents have been examined and thousands of physical and electronic sources have been interrogated to identify and disclose all material which might affect the safety of convictions. In addition, Peters & Peters liaised with a number of third parties including Fujitsu Services Limited, Royal Mail Group, the Courts, the CCRC and approximately 50 law firms and agents instructed by Post Office to obtain material relevant to the convictions.


Eligibility for compensation

Anyone who has successfully appealed against a Horizon-related conviction can apply for compensation via arrangements Post Office has put in place for this. This includes administrators acting on behalf of estates for any person who has sadly passed away.

Compensation payments

On 18 September 2023 the Government announced that anyone who was wrongly convicted and has had their conviction overturned as it was reliant on Horizon evidence, will be given the option of settling their claim for compensation for an up-front sum of £600,000, without the need to bring a formal claim to Post Office. This is an entirely voluntary choice and anyone who does not want to accept this offer can continue with the existing process where each claim is assessed on its specific facts and individual circumstances.

Post Office offers interim and partial payments to eligible people, ahead of final settlements, to ensure that money reaches them as soon as possible.

You can find more information about progress of appeals and compensation here and information about help and support if you wish to consider an appeal against conviction.

The typical process looks like this

You can find information about assistance for appealing convictions on the Post Office website

The first step is to request disclosure. In accordance with Post Office’s duties as a former prosecutor, Post Office has a continuing duty to disclose material that may undermine the safety of convictions.

To proceed to disclosure, Post Office will need to verify your identity to make sure they are speaking with the right person – for this, they will ask you to email them photographs or scans of two documents. Please contact the Post Office Disclosure Team at or Post Office Disclosure, PO Box 807, Winchester SO23 5EQ, quoting the reference number on your letter. If you are unsure, you can email the team and they will ask for information to verify your identity.


After Post Office have verified your identity, they will contact you (or your legal representative if you have one) to confirm your identification is acceptable and to advise that the Post Conviction Disclosure Exercise (PCDE) material will be prepared. Once the PCDE material has been finalised they will then contact you or any Legal Representative appointed to arrange for this to be sent.

You can then decide whether you would like to Appeal your case. This process could involve submitting your application to the CCRC – Criminal Cases Review Commission ( You can find out more about the CCRC and Post Office cases on their website here: Post Office / Horizon scandal – Criminal Cases Review Commission (

Anybody who thinks that their conviction might be affected by the issues with the Horizon system can contact the CCRC directly on 0121 233 1473 or find out more at
