help! - % workers paid less than monthly stats please

Do you mean less frequently than monthly?  The minimum pay reference period is 31 days for the purpose of the minimum wage. If someone’s payments are more than a month apart, eg bi-monthly, then they still have to receive the minimum wage each month.

I think ONS collect pay frequency information as part of the Annual Survey Hours and Earnings (and they also collect it in the Monthly Wages and Salaries Survey)

Unfortunately, pay frequency doesn’t seem to appear in the output statistics - but they give an email and phone contact on

so you could try asking them.

Looks like they may have this info but will charge for providing it

Gauke said today in the select committee hearing that 69% of people claiming Tax Credits were paid either monthly or 4 weekly
