State Employees Retirement Benefits Act 1979

If an employer does not within 14 days after being required to do so by the Board under section 34B pay into the Fund the whole amount of the sum determined under that section as representing the employer's liability, the employer must, if the Board so demands, pay interest at the rate for the time being fixed under section 2 of the Penalty Interest Rates Act 1983 on the amount remaining unpaid from the date on which payment of it was required by the Board until the date on which it is paid into the Fund.
