The Superannuation (Local Government and Federated Schemes Employment) Interchange Rules 1969
These Rules provide for the aggregation of service and for a single superannuation award in cases where persons transfer within the prescribed period (generally 12 months) from pensionable employment with a local authority in England or Wales to employment entailing membership of the Federated Group Pension Scheme or of a Federated Pension Scheme for Individual Employers, and vice versa. Where such a transfer is made the person is enabled, subject to the payment of an appropriate transfer value, to reckon previous service for pension under the superannuation scheme to which he transfers.
