That's not my experience and there is nothing on the .gov website to suggest this is the case.
Ime there is absolutely no requirement to work until State Pension age to get the full State Pension.
The only requirement is 35 years full NI contributions.
Myself and at least two friends all retired well before our State Pension ages and now receive the full State Pension - two of us, including me, get this plus additional S2P/SSP payments.
If you have any different info' to the aforementioned position perhaps you could provide a link?

There is a lot of confusion around this subject tbh.
One is the 'why do I have to keep paying NI if I have 35 years of full contributions?' which is answered below - basically you continue paying until State Pension age IF YOU WORK to fund people who are in a situation where through no fault of their own they do not have enough NI years of their own and never will do.

NB: please read the above article thoroughly. The scheme is that 35 full years NI contributions will give you a full State Pension.
However, due to various scheme changes over the years SOME people may have to make up any shortfalls accrued under previous schemes - this is where things can get very messy and MAY mean that there will be a shortfall on the amount of State Pension you will be paid (despite having 35 years full payments) and you MAY be able to compensate for this with extra payments.
If in doubt check your personal forecast with HMRC or a qualified person eg your accountant etc.
This will give you the amount you will receive based on your current level of contributions and the current rate of State Pension payment.
Qualifying years may change over time subject to Government whims plus the State Pension amount generally rises annually although there is nothing to say it cannot remain static year to year.
