The changes to the scheme follow recommendations in Sir Brian Langstaff's additional report published on 9 July.
Minister for the cabinet office and paymaster general, Nick Thomas-Symonds, said: ‘I have concentrated on removing barriers to quicker compensation, working with IBCA, and am determined to deliver improvements based on this new report.
‘Our focus as we move forward must be working together to not only deliver justice to all those impacted, but also to restore trust in the state to people who have been let down too many times.'
The changes mean up to over a thousand people who endured treatments with adverse side effects, such as interferon, will receive higher compensation to what is currently provided.
There will also be further compensation for the impacts currently recognised by the Infected Blood Support Scheme ‘Special Category Mechanism' provided to chronic Hepatitis C individuals who have experienced a significant impact on their ability to carry out daily duties.
In addition, if the affected person has died or dies after 21 May 2024, their estate will be able to make a claim.
Announcing the changes in Parliament, Thomas-Symonds revealed Clive Smith, president of the Haemophilia Society, will be the chair of the Infected Blood Memorial Committee.
Smith will lead the work to create a national memorial to the victims of the Infected Blood Scandal and develop plans for commemorative events with the first to be held at the end of 2025.
