This Practice Note outlines the requirements to report a claim to the Compensation Recovery Unit (CRU) and the procedures followed when applying for a CRU certificate, requesting a review, mandatory reconsideration and appeal of a CRU certificate detailing recoverable benefits and lump sum payments. Separate legislation covers the recovery of NHS charges. For guidance on requesting and challenging a certificate of NHS charges, see Practice Note: Recovery of NHS charges. Recovery of social security benefits A claimant will often receive state benefits as a result of their accident, injury or disease. The Department for Work and Pensions (DWP) operates a system for recovering these benefits from the compensator (either the defendant or, in most cases, the defendant’s insurers) via the Compensation Recovery Unit (CRU). For further information, see Practice Note: Recovery of social security benefits. Reporting requirements The CRU operates an online system which allows compensators and their representatives to: • register a claim • request a CRU certificate • notify the CRU of claim settlement • make any relevant payments
