My DB scheme assumes I will be entitled to the full state pension at 65 which is no longer the case, and maybe never was as I may not reach 2080 credits by my 65th birthday.
It is very strange (and unusual) that your DB scheme would assume that you will get the full State Pension. What if an employee joined the scheme and left after 5 years and emigrated? What if someone had joined the DB scheme in their forties?
The more usual assumption in a DB scheme is that a member will get a State Pension commensurate with their length of service in the Scheme, eg, after 15 years service assume that the person will get 15/40 of the State Pension.
Jut to note also that up until 2014 there was a State Pension (Transition) payable at 65 with the State Pension (COAP) payable from 66 (as now). There were slightly different rules for the Transition Pension.
