I would agree with what factor-fiction and dasherman have said.
From my knowledge of pensions, the rules do not allow you to access money from your deferred House of Fraser pension until you reach 55.
Possibly House of Fraser are being very naughty and getting out of future pension liabilities by paying you off – and damn the consequences. Claiming that the money has been released to you, specifically to invest in another pension scheme (knowing that is not the case).
For every £1 of annual pension pay-out, House of Fraser should be paying you close to £20. Without knowing what your pension is projected to pay-out at age 65, you cannot make an informed decision as to whether taking the money is a good deal or not.
If you do take the money, make sure you keep copies of all paperwork received and sent – if at some future date your tax liabilities are questioned in relation to the pay out; you may be able to claim compensation from House of Fraser.
