Assurance reports & thematic reviews

We have a three-layered approach to the validation and assurance of claims.

This approach takes account of risk and the need for public assurance, as well as making sure MPs or their suppliers are reimbursed as quickly as possible.

Since 2017, we have published an Annual Review of Assurance which summarises all the validation and assurance work during the year.

As well as the individual validation of MPs' claims and a quarterly review of each MP’s expenditure, our assurance team (which is separate from those members of staff conducting the earlier validation) carry out a programme of assurance reviews of aggregate spending by MPs in a range of categories.
