I'd retire later if I got a higher pension rate.

i.e.

Opt to retire at 65, but you get a defined contribution pot

Opt to retire at 70, you get final salary pension.

FWIW, the UK state pension does go up if you defer it: https://www.gov.uk/deferring-state-pension/print

Yeah, but I want 2/3 of my salary when I retire, not £300/week.

Your private pension is only 70 a week?
