The government are currently working on proposals to make it compulsory for all final salary schemes to insure themselves against losses in their schemes. Even if this proposal goes ahead, it will take some years for this to be implemented. To answer your question about whether you can effect insurance yourself, I would guess that your chances of finding a company to underwrite this are slim to none. I imagine the only insurer that might conceivably consider this would be a niche Lloyds syndicate, but I imagine the premiums would be pretty steep and you might be better off saving any money otherwise spent on premiums to put towards your retirement, or invest in an AVC/FSAVC, which will attract tax relief.
