Glad you asked that question Stanley, I am very similar to you - I left in late 2014 on PVR at 53 and will be 65 in 2026 (I'm sure you meant 2027 not 2017).
However, I wasn't aware of the need to claim or apply for my full pension and second lump sum so I look forward to someone answering your question.
I `ve just spoken to the Pension People in Glasgow.
They say that because our existing EDP (following AFPS05 `PVR`) is not classed as a `pension`, then the full pension benefits/2nd lump sum that we expect to obtain at age 65 under AFPS05 are classified as a `Preserved Pension`.
I was told that I WOULD therefore have to formally claim for those benefits by sending a completed
`AFPS Pen Form 8`. This form is easy to download via the internet.
(For
currently serving personnel shortly approaching their retirement date, the
`AFPS Pen Form 1` should be used, so it`s important to use the correct form or your application could get `spat out` by the system).
Hope this helps!!
