...one of your options

If you have a Deferred pension under RIGPS you may be able to retire early and take the pension from age 55 (increasing to age 57 on 6 April 2028). However, it may be reduced to reflect the fact that it will be paid sooner and therefore potentially over a longer period.

You should contact the Pensions Administration Team in good time if you are planning to retire early. They will be able to help you by telling you the expected amount of your (early) retirement pension and confirm whether there are any options, such as taking a tax-free cash lump sum and a reduced pension, or arranging additional pension for a dependant in the event of your death, as well as any terms or conditions that may apply to your pension - especially depending on the rules applicable to the Scheme at the date you left and / or current rules and tax law.
