If a business is transferred from one owner to another, your terms and conditions of employment are automatically transferred as well. The position with regards to pensions is more complex.
Your rights derive from legislation called the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE). The effect is as if your contract of employment had been agreed with the new owner at the start of your original employment. Not only are your terms and conditions of employment transferred but all the liabilities of the previous employer are also transferred. There is an exception for pension rights.
The effect of TUPE on pensions depends on the type of pension arrangements you had with your old employer and whether you worked in the public or the private sector.
In the private sector, TUPE does not require the new employer to match the pension you had from your old employer, but what they must offer depends on your old employer’s pension arrangements. You can check the position on the website of the Pensions Advisory Service.
The position is different in the public sector. In most cases, your employer will be required to offer you either continued membership of your existing public sector scheme or another “broadly comparable” scheme. There is information available from the Pensions Advisory Service and also from individual public service unions.
TUPE only applies where the identity of your employer changes. It does not normally apply where the owner of the shares in your employer changes but the identity of your employer stays the same.
Your employer must give you proper advance notice of any takeover before it happens, if it means your employer will change.
If your employer expects your terms and conditions (including your pension) or the way in which you work to change as a result of any takeover or merger, your employer is legally required to consult in advance about those changes. Consultation must be through your union if one is recognised where you work.
