If you think you will be getting a 5.2% increase on your military pension think again. It was only the basic State old-age pension that got the full index link last year and it will probably be the same next year.
My SERPS element, my military pension and my CS pension all increased at a lower rate. I heard 3% might be nearer the mark.
5.2% IS the lower rate (CPI - which we got on the military pension last year) The basic state pension last year was the last of the RPI years which is why there was a difference - they are all CPI now.
