Hi Cecelia, the amount of pension payable to you at 60 will not be any less because you are on a D rate.
If you had been on an A rate since 1995 then at 60 you would have been eligible for an Occupational Pension plus (on application and on meeting eligibility conditions) a Supplementary Pension. The combined Occupational Pension + Supplementary Pension should equal the D rate pension you are on course to receive. At 67 you will not be eligible for a State Pension as an A rate pensioner would be. But at 67 the A rater loses their Supplementary pension, so again their combined Occ. Pension and State Pension should be roughly equivalent to your total D rate pension.
In sum, and without getting further bogged down in details, you aren't disadvantaged pension-wise - unless there is something else you are concerned about ?
However I'm recently been informed that I am probably on the wrong class and should have been on class A since 1995.
Who informed you of this ? Was it HR? I don't know whether or not you should have been put on an A rate in 1995 but if I was in your shoes I wouldn't be making an issue of it now, unless it is you employers who are making it an issue. (It is more usually A raters who complain about being disadvantaged).
Hi I'm 57 and have worked in the health service since 1983 full time............... I'm due to retire in 3 years
On a separate matter, it sounds like you are a couple of years short of full service. You should consider getting a quote for notional service from your HR. Even though you are retiring at 60 I think you can purchase notional years -check it out with HR.
2 years extra of notional service would increase your annual pension by 1/40 of pensionable salary and your lump sum by 3/40 (eg, on a salary of €60000 this would equate to annual pension of €1500 and a lump sum of €4500). Notional service purchase ( if eligible) is not cheap but you can pay it from your retirement lump sum and claim tax relief for the amount involved. It is particularly attractive if you are on the higher tax rate now but will be on the basic rate in retirement.
