Frequently asked questions

An IAR is a formal report verifying that you have met certain financial conditions, often tied to grant funding or regulatory oversight.

Any organisation receiving a grant, regulated by bodies like the SRA or CAA, or required to report on fund use and compliance.

Our IARs start from £800, with fees depending on claim size, transaction volume, and scope.

Often yes, but it depends on the grant terms. We advise checking your funding agreement.

Typically 2–3 weeks from receiving all information. Quicker if booked in advance.
