UK Minimum Wage Crackdown Repays Workers, Penalizes 658 Employers
The UK Government found that 658 employers had not correctly paid the legal minimum wage.
More than 27,000 workers received almost £4 million in back pay.
The employers were also given penalties totaling £7 million.
B&Q was one of the companies named, although it said its mistake was unintentional.
B&Q said the problem involved how geographical allowances were calculated and that workers were repaid in July 2025.
One hospital group said its case was a technical calculation issue rather than actual underpayment.
The Government wants companies to check their payroll systems more carefully.
A new agency will enforce minimum wage rules and may later handle holiday and sick pay cases.

More than 27,000 workers were repaid almost £4 million.
