658 UK Employers Named for Minimum Wage Violations: £4m Recovered in Government Enforcement Sweep

The Department for Business and Trade has publicly named 658 UK employers for paying staff below the minimum wage, ordering the firms to repay £4 million to affected workers and issuing penalties totalling £7 million^[1]. The enforcement sweep, announced on 2 September 2026, includes household names such as DIY retailer B&Q^[1] and fast-food chain Five Guys, alongside nursing homes, childcare providers, and NHS trusts.

Scale and Scope of Violations

The named businesses span multiple sectors, with the government list including "shops, restaurants, nurseries, social care providers and a handful of NHS trusts"^[1]. The Department for Business and Trade did not specify the time period over which the underpayments occurred^[1].

Current minimum wage rates in the UK stand at £12.71 per hour for workers aged 21 and over, £10.85 for 18 to 20 year olds, and £8 for under-18s and apprentices^[1]. The enforcement action represents one of the largest public naming exercises conducted by the government for wage violations.

High-Profile Cases

B&Q underpaid 4,530 workers a total of more than £456,000, according to the government^[1]. The retailer attributed the shortfalls to "calculations involving geographical allowances which are paid in addition to minimum hourly rates," describing the underpayments as unintentional^[1]. The company stated that "all affected colleagues were quickly paid in full in July 2025"^[1].

Five Guys was named for owing over £54,000 to 3,699 staff^[1]. The company blamed "technical differences in how payroll regulations were applied" for the violations, which were identified during a review by HMRC^[1]. Five Guys said it "worked closely and transparently with HMRC throughout the process and have made all required payments to affected current and former employees"^[1].

Healthcare Sector Compliance Issues

Multiple NHS trusts appeared on the enforcement list. St George's, Epsom and St Helier Hospital Group failed to pay over £123,000 to 75 workers, while St George's University Hospitals in Wandsworth, London, underpaid 55 workers^[1].

A spokesman for the two hospital trusts contested the characterisation, stating that "no colleagues were underpaid" and that the issue "relates to a technical compliance issue where part of their salary for a non tax-deductable 'salary sacrifice' (for example, towards childcare) was not counted towards the national minimum wage, even though their gross salary was above the national minimum wage"^[1].

Norfolk Community Health and Care NHS Trust acknowledged that apprentices were inadvertently underpaid between 2019 and 2023^[1]. While their pay met requirements for contracted hours, "meetings, handovers and time spent changing into uniform hadn't been accounted for," according to a trust spokesperson^[1]. The trust has since changed its policies and practices.

Implications for Directors and Compliance

The public naming exercise serves as both a penalty and a deterrent mechanism. Companies found to have underpaid staff face not only the requirement to repay outstanding wages but also financial penalties - in this case totalling £7 million across the 658 named employers^[1]. The reputational damage from public disclosure can be substantial, particularly for consumer-facing brands.

Common technical violations cited by the named companies include failures to account for uniform changes, handover periods, and salary sacrifice schemes when calculating minimum wage compliance. Geographical allowances and payroll system configurations also emerged as recurring technical issues leading to underpayment.

For company directors, the enforcement action highlights the importance of regular payroll audits and understanding how working time, allowances, and deductions interact with minimum wage calculations. HMRC's review process, which identified Five Guys' violations, suggests ongoing scrutiny of payroll practices across sectors.

UK Register Context

Across the broader UK company register, 5.57 million companies are currently active^[2] out of a total 6.63 million registered companies^[2]. The economy-wide register shows London hosting 1.03 million registered companies^[2], followed by Manchester with 100,879 and Birmingham with 90,404^[2]. These figures represent all registered companies, not specifically those in sectors affected by the minimum wage enforcement action.

In the past seven days, 10,346 new companies were incorporated across the UK^[2], reflecting ongoing business formation activity separate from the enforcement sweep.

Forward-Looking Enforcement

The scale of the 658-employer naming list - more than double typical quarterly enforcement rounds - suggests either an expansion of HMRC's audit capacity or a backlog of cases being cleared. The lack of a specified time period for the underpayments indicates the list may consolidate multiple years of enforcement activity.

Business Secretary Jonathan Reynolds is expected to emphasise the enforcement action as part of the government's worker protection agenda, though the specific policy context was not detailed in the initial announcement^[1]. The £4 million recovered represents an average of approximately £6,079 per employer, though the distribution is uneven, with B&Q's £456,000 alone accounting for over 11% of the total.

For businesses in retail, hospitality, healthcare, and social care sectors - all represented on the list - the enforcement action underscores the compliance risks inherent in complex payroll arrangements, apprenticeship schemes, and non-standard working patterns. Technical errors, while often unintentional, carry both financial and reputational penalties when they result in workers receiving less than the legal minimum.
