The minimum premium rate. The minimum premium rate ensures all employers pay their fair share of the Scheme's administration costs. This includes the fixed costs of underwriting each policy and other non-claim related expenses. For the 2023-24 policy year the minimum premium rate is set at 1.06 per cent.
