Welcome to the Post Office Horizon IT Inquiry website

This is an independent public statutory Inquiry established to gather a clear account of the implementation and failings of the Horizon IT system at the Post Office over its lifetime.

New Postal Address

From 1 April 2025, the Inquiry will be moving from the 5th floor of Aldwych House, to a new office space on the 2nd floor.

Please note our new postal address will be: 2nd Floor, Aldwych House, 71-91 Aldwych, London, WC2B 4HN.

What’s next for the Inquiry?

The Inquiry’s public hearings have now concluded, but it is important to note that there is still important work that is happening behind the scenes.

Moving forward, the Inquiry will continue analysing evidence, drafting the final report and will then begin a process known as Maxwellisation. This is where, under Rule 13 of the Inquiry Rules 2006, the Inquiry needs to give anyone who is criticised in the report a reasonable opportunity to respond.

Then we will focus on publishing the report and all the evidence that has been shown in hearings and mentioned in witness statements.

We will also ensure that, as the Inquiry concludes, there is a comprehensive and well-ordered record of the Inquiry which will be transferred to The National Archives.

In a statement, Sir Wyn Williams, Chair of the Inquiry, said: “People have waited long enough to hear the truth about events that had such adverse consequences on their lives. So, I am determined to provide answers to those directly affected as swiftly as possible."
