If you have stopped paying in to USS but you remain in USS-eligible employment, you may still be able to flexibly retire. This is subject to agreement with your employer.
You’ll need to reduce your working hours by at least 20%, and your pay will also need to reduce by the same percentage.
Flexible retirement is not available if you’re no longer paying in to USS, and no longer in USS-eligible employment. In those circumstances, you must take your Retirement Income Builder benefits all at once. Any Investment Builder savings can remain invested until you need them.
