How your pension increases and GMPs
Each April, if you’re 55 or over and taking your LGPS pension, (or under 55 and have a dependants or ill-health pension), your pension will be increased each year in line with the cost of living. This is based on Consumer Price Index (CPI) as at September of the previous year.
If you're under 55 and you're receiving a pension for any other reason, it will normally be paid at a flat rate until 55. At 55 your pension will increase to the amount it would've been, had the increases been added to your pension from your date of leaving.
