If the worst does happen and the company goes belly-up, taking the pension money with it – the good news is that in such circumstances the government will step in and pay you 90% of what you otherwise would have received, had your pension paid out normally.
The only down side – and it is a significant down side, is that the pension paid by the government (at 90%) is fixed at the amount first paid, and not indexed linked with inflation.
The rules of pension schemes are such that those who have already retired get first claim on any pension money remaining – if there is not sufficient to pay out those yet to retire, then they are protected (as detailed above).
Therefore it might be best to sit tight, hope the company does not fold, even if you are made redundant. If you take your pension now, there may be a significant reduction for taking it early – which might be worse than the 90% you would get from the government.
You can always ask your pension service what they would pay you at age 55 – but normally such final salary schemes will not allow you to draw your pension while you are still employed by the company.
