prpFrequency

This is the period of time over which earnings are to be measured and is defined by the automatic enrolment rules. We have more information in our What’s a pay period (PRP)? article on The People’s Pension web site, and The Pensions Regulator provides further guidance for calculating the relevant pay reference period.

For example, if an employee is paid weekly, the pay period would be one week and if they are paid monthly, the pay period would be one month. The minimum pay period is one week. See payReferencePeriod for worked examples.

To align with the pay frequency used to calculate PAYE and National Insurance contributions, the pay period can be a tax week, or a tax month.
