Common Myths About Hourly Pay and Overtime After the National Minimum Wage Increase

With the latest national minimum wage increase taking effect in April 2026, it’s a good time to clear up some persistent misconceptions about how hourly pay works, how overtime is calculated, and what your annual salary really means. Whether you’re a job seeker comparing offers or an employee checking your payslip, understanding these myths can help you avoid costly mistakes.

Myth 1: The National Living Wage Is a ‘Living Wage’ for Everyone

Many people assume that the National Living Wage (NLW) is enough to live on comfortably anywhere in the UK. In reality, the NLW is a legal minimum – not a calculation of living costs. From April 2026, the rate for employees aged 21 and over rises to £12.71 per hour (a 4.1% increase, as confirmed by GOV.UK National Living Wage rates). For a full-time worker on 37.5 hours a week, that works out at roughly £24,784.50 per year before tax.

But the UK median full-time hourly pay (excluding overtime) was £19.67 in April 2025, according to the ONS Annual Survey of Hours and Earnings (ASHE). That’s over 50% higher than the NLW. The NLW is a floor, not a target. Many roles – especially in London or with specialist skills – pay well above it. Also, the NLW increase interacts with frozen tax thresholds, meaning take-home pay may not rise as much as the headline rate suggests, particularly for those not receiving Universal Credit.

Myth 2: Overtime Is Always Paid at Time and a Half

UK law does not require employers to pay a premium rate for overtime. The only legal obligation is that your average pay for all hours worked (including overtime) must not fall below the National Minimum Wage. Many contracts do offer time-and-a-half or double time, but it’s not universal. Some jobs – especially in retail, hospitality, or salaried roles – pay your normal hourly rate for extra hours. Always check your contract or speak to HR.

If you are paid hourly, overtime simply adds to your total hours. For example, if you earn £12.71 per hour and work 5 extra hours in a week, you’d earn an additional £63.55 (before tax). But if your contract says overtime is voluntary, you cannot be forced to work it. And if you are on a salary, your annual pay may already include a set number of ‘reasonable’ overtime hours.

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

A common mistake is to multiply an hourly rate by 40 hours and 52 weeks to get an annual figure. In reality, many full-time jobs are based on 37.5 hours per week (common in the NHS and office roles) or 35 hours. The ONS defines full-time as more than 30 paid hours per week (or 25 for teachers). Using 40 hours can overstate your expected annual pay.

A better rule of thumb: annual salary ≈ hourly rate × weekly contracted hours × 52. For the NLW at 37.5 hours: £12.71 × 37.5 × 52 = £24,784.50. For the UK median hourly pay of £19.67: £19.67 × 37.5 × 52 = £38,358.30 (close to the ONS median annual figure of £39,039). Use our Hourly to Salary converter to check your own figures.

Also remember that annual salary figures from surveys like ASHE include only employees who have been in the same job for at least a year, and they exclude overtime, bonuses, and unpaid leave. Your actual pay may differ.

Myth 4: London Weighting Is the Same for Everyone

London weighting (or High Cost Area Supplements) varies widely by employer and sector. For example, NHS pay scales for 2026/27 include separate HCAS rates for inner and outer London. A Band 5 nurse in inner London might earn an extra 20% of basic salary (minimum £5,794, maximum £8,746), while outer London gets a lower supplement. Other employers may offer a flat £X per year or a percentage. Always check your contract for the specific London allowance.

Myth 5: The National Minimum Wage Increase Automatically Boosts Your Take-Home Pay by the Same Percentage

GOV.UK’s analysis of the 2026 NLW increase shows that the impact on take-home pay depends on your tax and benefit situation. For a single person working 35 hours per week at the NLW, the weekly take-home increase is about £11.90 (3.3%) – less than the 4.1% headline rise – because frozen tax thresholds push more income into higher tax bands. However, workers receiving Universal Credit may see a larger net gain because the UC standard allowance is rising by 6.2%.

How to Use This Information

When comparing job offers or negotiating pay, always look at the total compensation package: base hourly rate, guaranteed hours, overtime policy, London weighting, pension contributions, and any bonuses. Use our salary data page to see typical pay for your role and region. And remember that the national minimum wage increase is a legal floor – you are entitled to at least that, but many jobs pay more.

Key Takeaways

• The National Living Wage rises to £12.71/hr from April 2026, but the UK median hourly pay is much higher at £19.67.
• Overtime is not legally required to be paid at a premium rate – check your contract.
• Annual salary conversions should use your actual contracted hours, not a generic 40-hour week.
• London weighting varies by employer and location.
• The national minimum wage increase does not always translate into a proportional rise in take-home pay due to tax and benefit interactions.
