The Department told us that it is confident the level of uncertainty over the number of potential claimants in HSS will reduce over the 2025–26 financial year. The uncertainty over the number of potential claimants within the HSS was a key reason for the C&AG’s qualification of the Annual Report and Accounts 2023–24. For HCRS, the uncertainty over the claim values was a key reason for the C&AG’s qualification.17 The Department confirmed there is ongoing uncertainty over the value of the smaller number of fully assessed claims within the HCRS, as they are expected to take longer to resolve.18
