What the National Minimum Wage really means for UK employers

IT’S NOT JUST ABOUT THE MINIMUM WAGE: THE TRUE COST OF HIRING STAFF.
Employers across the UK are reminded that paying staff isn’t simply about agreeing on a salary. Compliance with the National Minimum Wage (NMW) is only the starting point.
The NMW sets the legal minimum hourly pay for workers, varying by age and whether the employee is an apprentice.
The 2025 rates are:

£12.21 for workers aged 21 and over
£10.00 for workers aged 18 to 20
£7.55 for workers under 18
£7.55 for apprentices

However, the true cost of hiring extends far beyond these figures. Employers must also consider National Insurance contributions (NICs), pension payments, benefits, recruitment costs, training, and equipment.
For example, an average 37.50 hour workweek at the NMW of £12.21 totals £457.86.
Employer National Insurance at 13.8% adds £63.18, and holiday pay (currently at 12.07%) adds a further £55.21. This brings the total cost of hiring a minimum-wage employee to £576.25 per week.
We spoke with one business owner who said ‘the cost of employees used to be reasonably affordable, but I simply can’t do it anymore, I can’t afford to hire anyone, as it’s not just the NMW that’s increased, it’s everything else’. Running a business has never been as hard, its not surprising so many are choosing/forced to close’.
Employment experts caution that businesses must plan carefully to avoid underestimating total staff costs. “Many new employers think the NMW is all they need to budget for, but the additional costs add up quickly,” says HR consultant Jane Roberts.
With staff shortages continuing across sectors such as hospitality, retail, and healthcare, understanding the real cost of hiring, not just the minimum wage, is crucial for sustainable business planning.
