Common Myths About Hourly Pay and Overtime

When it comes to understanding your pay, myths and misconceptions can lead to confusion – especially around overtime, minimum wage, and how hourly rates translate into annual salary. Whether you’re comparing the minimum wage in Ireland with UK rates, or simply trying to work out what your job is really worth, it’s important to separate fact from fiction.

This article uses the latest official data from GOV.UK, the Office for National Statistics (ONS), and NHS Employers to debunk three persistent myths about hourly pay and overtime in the UK.

Myth 1: Overtime Is Always Paid at Time-and-a-Half

Many people assume that any work beyond their contracted hours must be paid at a premium rate – typically 1.5 times the normal hourly rate. In reality, UK employment law does not mandate overtime pay. The only legal requirement is that your total earnings for the pay period do not fall below the National Minimum Wage (NMW) or National Living Wage (NLW) for each hour worked.

For example, if you earn £12.71 per hour (the NLW from April 2026) and work 40 hours in a week, your employer must pay you at least £508.40. If you work 45 hours, the minimum is £571.95. There is no legal obligation to pay extra for the five overtime hours unless your contract specifically promises a higher rate.

Many collective agreements and sector-specific contracts do offer enhanced overtime rates, but it is not a universal right. Always check your employment contract or staff handbook. The Hourly to Salary tool can help you see what your base pay looks like annually, but overtime calculations depend on your individual terms.

Myth 2: The Minimum Wage Is the Same for Everyone

Another common misunderstanding is that there is a single minimum wage that applies to all workers. In fact, the UK has several bands depending on age and apprenticeship status. From April 2026, the rates are:

• National Living Wage (21 and over): £12.71 per hour
• 18-20 year old rate: £10.85 per hour
• 16-17 year old rate: £8.00 per hour
• Apprentice rate: £8.00 per hour (for apprentices under 19, or those 19+ in their first year)

These rates are set annually by the government following recommendations from the Low Pay Commission. While the minimum wage in Ireland is set by a separate body (the Low Pay Commission in Ireland) and follows its own schedule, the UK system is age-differentiated to reflect training and experience.

It’s also worth noting that some sectors, such as the NHS, have their own pay scales that start above the minimum wage. For example, NHS Band 3 (entry level) begins at £13.17 per hour in 2026/27, well above the NLW. You can explore more sector-specific data on our salary data page.

Myth 3: Annual Salary Is Simply Hourly Rate × 40 Hours × 52 Weeks

Many job adverts quote an annual salary based on a 40-hour week, but the standard full-time working week in the UK is often 37.5 hours (especially in the public sector and many office jobs). The ONS Annual Survey of Hours and Earnings (ASHE) defines full-time as more than 30 paid hours per week (or 25 for teaching professions).

To convert an hourly rate to an annual salary, a more accurate formula is:

Annual salary ≈ hourly rate × contracted weekly hours × 52

For a 37.5-hour week at the NLW of £12.71:

£12.71 × 37.5 × 52 = £24,784.50

If you work 40 hours, it would be £12.71 × 40 × 52 = £26,436.80.

However, these figures assume you are paid for every week of the year with no unpaid leave, and that you receive no bonuses, tips, or salary sacrifice deductions. The ONS reports that median full-time gross annual earnings in April 2025 were £39,039 – equivalent to about £20.02 per hour at 37.5 hours. That figure includes overtime and bonuses, so your own conversion may differ.

The Reality of Overtime and Pay

Overtime can be a valuable way to boost income, but it’s not always as lucrative as people think. Some employers pay overtime at plain time (your normal hourly rate), while others offer enhanced rates. The key is to understand your contract and know your rights.

If you are paid below the minimum wage for any hour worked – including overtime – you can report it to HMRC. The government’s minimum wage calculator can help you check compliance.

London Weighting and Sector Differences

In London and other high-cost areas, many employers add a weighting to base pay. For example, NHS pay scales include High Cost Area Supplements (HCAS) that can add several thousand pounds to annual salary. A Band 6 nurse in inner London might earn over £20 per hour, while the same role in a rural area starts lower.

Final Thoughts

Understanding your pay is essential for financial planning and career decisions. Don’t rely on hearsay – check official sources like GOV.UK for minimum wage rates, ONS for earnings benchmarks, and your own contract for overtime rules. And if you’re comparing UK rates with the minimum wage in Ireland, remember that each country sets its own rates independently.
