Claims Process and Evidence Requirements

Last reviewed: April 2026

Claims are central to grant-funded projects. Teams that treat claims as an administrative afterthought usually discover missing records, inconsistent dates, or scope drift.

Evidence categories

  • approval and scope records
  • invoices
  • proof of payment
  • delivery or completion evidence
  • acceptance records
  • milestone evidence where required

Claims and reporting differences

  • Grants: claims usually require invoice, payment, and delivery evidence mapped to approved scope.
  • Pilot and accelerator programmes: evidence is often milestone or output reporting rather than claim reimbursement.
