For those in the public sector, where the pension age is now the state pension age, you might be able to claim the pension linked to your earlier service (ie pre Apr 2022) if you started before 2005.
As a civil servant that started in 2000, I can claim my 22 years service from 60 with no actuarial reduction. The years I've worked from 2022 onwards I can only have at state pension age - unless I opt to take it reduced.
Most of my colleagues go part time at 60, take the earlier pension and work 2/3 days a week and earn pretty much the same. Worth reading up what the McCloud judgement means for your pension scheme as I think it is similar.
