The date decides how much choice a committee has
Consider a term ending in February for a scheme whose annual meeting is in November. The committee had no reason to think about it at the meeting, has no delegated authority to run a process, and finds out about the expiry when a reminder arrives. There is no time to obtain comparable quotes, so the arrangement continues by default and the opportunity to examine it passes for another year.
Shift the same expiry to shortly after the budget is adopted and the position transforms. The committee has just considered the cleaning figure, has a fresh scope in front of it and has the whole notice period available to look at alternatives if it wants to. Nothing about the service changed; the scheme simply has choices it did not have before. Alignment done once holds for every subsequent renewal.
