Yes, you will be able to purchase added years over the remaining part of your service up to age 55. I believe though, in keeping with the current scheme, the maximum increase you can buy will be that required to bring you up to 35 years reckonable service at normal retirement age (provided this keeps you within Inland Revenue limits). I do not believe you would be able to contract to buy up to 40 years, since you could not guarantee to serve the extra time at the time of taking out the contract. The extra 5 years above normal retirement age must be attained by extra time actually served. That is my understanding (until someone proves me wrong again!). The reference for added years is JSP 764 Part 1 Chapter 5 (Paras 0501 to 0518).
