If a business is transferred from one owner to another your terms and conditions of employment, (except for pensions), are automatically transferred as well. Your rights derive from the Transfer of Undertakings (Protection of Employment) Regulations, commonly called TUPE.
If you are transferred to the new business your terms and conditions of employment, including your continuity of service, are protected. The effect of the transfer is as if you were still employed by your previous employer.
If you were entitled to join or were a member of your previous employer’s occupational pension scheme, then, under rules brought in by the Pensions Act 2004, the new employer must offer you the opportunity to participate in an occupational or stakeholder pension scheme.
