fatal memory error when displaying account_expiry page

Now that I have a user list of 350, when attempting to display account_expiry page I get a Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1648641 bytes) . As there is no pagination of the list, I assume that the cause is in attempting to list all 350 users and expiry dates on the one page. If so, can anyone suggest a solution other than increasing allowed PHP memory allocation.

Adding pagination would seem to be the obvious move, but I am no coder.
