Why did my pension deduction change?
The most common reasons are: a salary change moved your contribution band, your employer increased the default contribution rate, you opted into salary sacrifice, or your scheme switched between a percentage of qualifying earnings and a percentage of total earnings.

Check your pension scheme statement for the current contribution rate and qualifying earnings basis.
Auto-enrolment minimums in 2026/27 are 5% employee and 3% employer of qualifying earnings, but many employers contribute more or use a different earnings basis. A switch from "qualifying earnings" to "total earnings" with the same percentage will increase the absolute amount deducted.
If you were enrolled into salary sacrifice, the deduction often appears smaller on the payslip because pension is taken before tax and NI. Your gross pay line may also drop accordingly.
