Your pension will increase in line with the cost of living (Consumer Price Index) each April if you are over age 55. The increase takes effect from the first Monday after 5th April each year.
If you take your pension in the same year as your LGPS membership ended, there is an adjustment to the pension you built up from 1 April 2014 onwards. It is revalued up to the date of leaving in line with the cost of living. This adjustment applies in April after your leaving date in line with HM Treasury Revaluation orders.
If you joined the LGPS before 1 April 2014 and you take your pension in the same year as your LGPS membership ended, you may not receive the full increase in the first year. Instead you will receive a proportion of the increase based on the date you left the Scheme.
