The mechanics of it seem a bit murky, from past experience.
I have contacted past employers before (in their role as trustees of the scheme) and they have failed to respond. Then I contacted the pension company and they said that their contract was with the employer, not with the individual member and they would only provide details to the employer. At this stage I wrote to the trustees and copied the Pensions Board, pointing out their statutory obligations to provide this information. Shortly after this I got the information I required from the trustees.
Equally, I contacted another pension company directly and they provided the valuation to me without any problems. As above - the mechanics are a bit murky.
I still have one scheme I can't get a valuation for - it's on my list of things to do in the medium term. Basically the company I had worked for (and left) was taken over, the pension schemes were merged, the new company was taken over again, schemes merged, etc . . . and eventually I lost track of where the scheme should have been. I still know the pension company that handled the original scheme so I reckon with enough work they will be able to track it down. Obviously this type of situation causes some difficulties, especially where the employer has closed entirely - tracking the trustees would not be easy.
My advice is to *write* to the employers (well the trustees as set out in the original documentation you received - probably the HR and/or Finance people in the employer) asking for a valuation of your scheme and give them a reasonable period to supply the information - like 2-3 weeks. If the information still has not surfaced after that time, send the letter again, noting the failure to supply the information and indicate you are copying the Pensions Board. Then ring the trustees a few days later and ask for an update. Trustees have a statutory responsibility to scheme members whether they are still employees or not, so this should focus their attention.
