obligation to provide me with an annual pensions benefit statement?
I have been in several final salary public sector schemes and have always had a statement. I dont know what you mean by a quango scheme, but I work for a voluntary organisation, which is an 'admitted body' to a local authority scheme.
I get a pension benefit statement every year, usually about June/July giving my position as of the beginning of April. This is sent direct to my home address from the pension administrators and does not come through my employers at all. One of the things to watch is that the scheme have an up-to-date address for you if you have been a member for a long time.
I don't know if they have an obligation to provide you with a statement, but they generally all do.
