Minimum Wage 2025: Busting Common Myths About Hourly Pay and Overtime

Every year, the UK’s minimum wage rates change, and with them come a host of misunderstandings about how hourly pay works, how overtime should be paid, and what your annual salary really means. With the minimum wage 2025 rates now confirmed, it’s a good time to separate fact from fiction.

Myth 1: “If I earn above the minimum wage, I don’t need to worry about it”

Even if your hourly rate is higher than the National Living Wage (NLW) or National Minimum Wage (NMW), the minimum wage still affects you indirectly. The NLW sets a floor for the entire labour market. According to the Office for National Statistics (ONS), median full-time hourly earnings in April 2025 were £19.67 – well above the £12.21 NLW. But the proportion of low-paid jobs (those paying less than £11.97 per hour) fell to just 2.5%, the lowest since records began in 1997. That means the minimum wage is pulling up the bottom of the pay distribution, which can influence wage negotiations across many sectors.

Moreover, the ONS notes that around 447,000 employee jobs were paid below the NMW or NLW in April 2025. While this is an estimate and not a measure of non-compliance, it shows that underpayment still happens. Knowing the correct rate helps you check your own payslip.

Myth 2: “Overtime must always be paid at time-and-a-half”

This is one of the most persistent myths. UK law does not require employers to pay a premium rate for overtime. The only legal requirement is that your average hourly pay – calculated by dividing your total pay (including any overtime payments) by the total hours you worked – does not fall below the minimum wage for your age group. For example, if you earn £12.21 per hour for your basic 37.5 hours and then work 5 hours of overtime at the same rate, your average is still £12.21, so you are compliant. If your contract promises time-and-a-half, that is a contractual right, not a statutory one. Always check your employment contract.

Myth 3: “Annual salary = hourly rate × 40 hours × 52 weeks”

Many people assume a 40-hour week, but the ONS defines full-time as working more than 30 paid hours per week (or 25+ for teaching professions). In practice, many full-time roles are based on 37.5 or 35 hours. Using the wrong hours figure can over- or under-estimate your annual salary. For the minimum wage 2025, a 37.5-hour week at £12.21 gives an annual gross salary of £23,809.50. A 40-hour week gives £25,396.80. The difference matters when budgeting or comparing job offers.

To convert your own rate, use the formula: annual ≈ hourly × hours per week × 52. For a quick calculation, try our Hourly to Salary tool.

Myth 4: “London weighting is included in the minimum wage”

London weighting is an additional allowance some employers pay to offset higher living costs in the capital. It is not part of the statutory minimum wage. The NLW and NMW rates are the same across the whole of the UK. If you work in London, your employer may pay more, but they are not legally required to do so. The ONS data shows that median earnings in London are higher than the UK average, but that is due to market forces, not the minimum wage.

Myth 5: “Part-time workers don’t qualify for the minimum wage”

False. The National Minimum Wage applies to all workers, regardless of hours. Part-time employees are entitled to the same hourly rate as full-time employees doing the same job. The ONS reports that median weekly earnings for part-time employees were £280.00 in April 2025, up 6.4% from the previous year. Part-time workers should always check that their hourly pay meets the legal minimum.

How the minimum wage 2025 rates break down

GOV.UK published the following rates, effective from 1 April 2025:

• National Living Wage (21 and over): £12.21 per hour
• 18-20 Year Old Rate: £10.00 per hour
• 16-17 Year Old Rate: £7.55 per hour
• Apprentice Rate: £7.55 per hour (for apprentices aged 16-18, or those 19+ in their first year)
• Accommodation Offset: £10.66 per day (the maximum an employer can deduct for accommodation)

These rates are a significant increase from 2024, especially for younger workers. The 18-20 rate rose by 16.3% to £10.00, and the 16-17 rate rose by 18% to £7.55.

What about annual salary benchmarks?

According to the ONS Annual Survey of Hours and Earnings (ASHE), median gross annual earnings for full-time employees were £39,039 in April 2025. That’s roughly £20.02 per hour at 37.5 hours per week. The low-pay threshold (two-thirds of median hourly pay) was £11.97, and the high-pay threshold (1.5 times median) was £26.94. These benchmarks help you see where your pay sits in the national distribution.

Overtime and the minimum wage: a practical example

Imagine you are 22, paid the NLW of £12.21, and work 40 hours one week (35 basic + 5 overtime at the same rate). Your total pay is £488.40. Divided by 40 hours, your average is still £12.21 – legal. But if your employer paid you only £10.00 for the overtime hours, your total would be £427.35 + £50.00 = £477.35, giving an average of £11.93, which is below the NLW. That would be illegal. So while overtime doesn’t need a premium, it must not drag your average below the minimum.
