Why is my take-home pay less than last month?
Take-home falls when one of these changes: tax code, NI category, pension contribution rate, student loan plan, or a one-off payment from last month is no longer present. Compare line-by-line against last month's payslip and one number normally jumps out.

The cleanest method: list every gross pay item, then every deduction, side by side for both months. Any single change of more than £10 in a deduction line is worth investigating.
Common culprits beyond the obvious tax-code change include: an auto-enrolment pension increase, the second month after a pay rise where the higher rate of NI kicks in, a student loan that just crossed its threshold, and the first month after a workplace benefit (private medical, company car) was added.
If the difference is small and unexplained, the YTD totals on this month's payslip should still tell a consistent story year-to-date. If they do not, raise it with payroll.
