what are 'added years'?

Some salary related occupational schemes allow you to buy ‘added years’. This means that when you come to retire you will be treated as if you have worked for these added years, as well as the years during which you make a contribution.

They are unlikely to come cheap, but are a good way of getting a guaranteed increase in your pension, and may well be a better way to boost your pension than other top-up schemes such as AVCs or a stakeholder pension.
