If you have received your pension for less than 12 months you will receive a proportional adjustment (i.e. only part of the 10.1%).
The Increase is applied to your pension from 10 April. As this is part way through the month, you'll only receive a partial increase to your monthly pension payment in April. From May onwards you'll see the full increase.
Full details on the pensions increase, including payment and part year adjustments can be found on our Pension Increase page.
