Hundreds of employers across the UK have been named for failing to pay the legal minimum wage, in a fresh government enforcement round that small business owners should treat as a timely reminder rather than someone else’s problem.
The government says 389 employers were found to have underpaid workers by a combined £7.3 million, with around £12.6 million in penalties issued on top. The cases span sectors including care, retail, hospitality and manufacturing. Workers have been repaid what they were owed, but the wider message for SMEs is clear: payroll errors can turn into costly compliance problems, reputational damage and a lot of admin.
This matters even more because another rise in minimum wage rates is due from 1 April. For employers who run tight rotas, use younger staff, rely on apprentices or make deductions for uniforms, accommodation or training, now is a sensible moment to check that pay processes still add up.
What happened
According to the government announcement published on 19 March, the latest naming round covers 389 employers that failed to pay the National Minimum Wage or National Living Wage correctly. The state says this is the first round since a Budget commitment to publish enforcement action more frequently, and it comes just before the new Fair Work Agency begins operating on 7 April.
The headline figures are big, but the practical lesson for small firms is not only about deliberate underpayment. Minimum wage breaches often happen because payroll is more fiddly than it first appears. Time spent opening up, closing down or travelling between sites can count. The wrong apprentice rate can be applied. Salary sacrifice, deductions or unpaid working time can pull pay below the legal floor without an employer meaning to do it.
Why this matters for SMEs
Large companies may have specialist HR and payroll teams. Many smaller businesses do not. In a shop, café, garage, nursery, salon or trade business, wage calculations are often handled by the owner, an office manager or an external bookkeeper working from whatever records they are given.
That is where risk creeps in. If timesheets are incomplete, if staff regularly start work before their paid shift begins, or if payroll software has not been updated for the latest rates, a business can fall out of line surprisingly easily. And once HMRC starts asking questions, the cost is not limited to arrears. Management time disappears, paperwork piles up and customer trust can take a knock.
For firms already operating in a cautious economy, that kind of disruption is the last thing they need. We have already looked at the pressure that slower demand can place on margins in our piece on the UK economy flat in January. A payroll compliance issue on top of weak trading conditions can make a difficult year harder.
What small employers should check before 1 April
The first step is simple: review your hourly rates against the current legal minimums and the new ones that take effect from 1 April 2026. From that date, the published rates rise to £12.71 an hour for workers aged 21 and over, £10.85 for those aged 18 to 20, and £8.00 for under-18s and eligible apprentices.
Then look beyond the headline rate. Check whether staff are being paid for all the time they are actually working, including setup and shutdown tasks where relevant. Review deductions that could reduce effective hourly pay. Make sure apprentice status has been applied correctly. If you use payroll software or an outsourced bureau, confirm the settings have been updated rather than assuming it will happen automatically.
It is also worth keeping a clean audit trail. Accurate timesheets, rota records and payroll notes will not only help you spot mistakes early, they will make life much easier if an employee raises a concern or HMRC ever asks for evidence.
The practical takeaway
This latest enforcement round is a warning shot for every employer, not just the businesses named in the list. For SMEs, the safest response is not panic but a short payroll check before the April rate change lands.
If you employ staff, especially part-time workers, younger workers or apprentices, now is the time to confirm that your rates, deductions and recorded hours all line up with the rules. A quick review this week is likely to be far cheaper than sorting out arrears, penalties and reputational damage later.
