2.16 In a long contract it is essential to include clear arrangements for the return of assets at the end of the contract period or on earlier termination, so that National Savings is free to choose an alternative supplier through a competitive process. SBS has to ensure that assets, supplier contracts and employee terms and conditions are maintained in an agreed condition to allow continuity of service with a new provider. In the pre-handback period, one year before expiry of the contract, SBS cannot alter the terms of employment of staff, dispose of any assets or alter key contracts with suppliers without the agreement of National Savings. SBS will bear the costs of complying with the handback requirements, and must provide information for National Savings to use in re-tendering the services. Following termination, SBS is also required to co-operate fully over a maximum period of six months to achieve a smooth, orderly and efficient transfer.
