Minimum Wage for 18-Year-Olds in 2025: What You Need to Know

If you are an 18-year-old employee in the UK, or an employer hiring young workers, the minimum wage for 18 year old 2025 is set at £10.00 per hour from 1 April 2025. This rate applies to all workers aged 18 to 20, and represents a substantial 16.3% increase on the previous year’s rate of £8.60. The government announced the rise following recommendations from the Low Pay Commission, aiming to support younger workers as the cost of living rises.

Understanding how this hourly rate translates into a weekly or annual salary is essential for budgeting, job comparisons, and checking your pay entitlement. This guide explains the conversion, the difference between part-time and full-time assumptions, and how the 18-20 rate fits into the wider UK pay landscape.

Hourly Rate to Annual Salary: The Basic Conversion

To convert an hourly wage to an annual salary, you need to know the number of hours you work each week and multiply by 52 weeks (assuming you work all year, with paid holiday). The standard full-time week in many sectors is 37.5 hours, though some roles use 35, 40, or even 45 hours. For the minimum wage for 18-year-olds:

• 37.5 hours per week: £10.00 × 37.5 × 52 = £19,500 per year
• 30 hours per week (common part-time): £10.00 × 30 × 52 = £15,600 per year
• 20 hours per week: £10.00 × 20 × 52 = £10,400 per year

These figures are gross (before tax and National Insurance). The Hourly to Salary tool on this site lets you plug in your own hours to get an instant estimate.

Part-Time vs Full-Time: Why Hours Matter

The official definition used by the Office for National Statistics (ONS) in its Annual Survey of Hours and Earnings (ASHE) defines full-time as working more than 30 paid hours per week (or 25 for teaching professions). Part-time is 30 hours or fewer. For an 18-year-old on the minimum wage, working 30 hours a week would classify you as part-time, but your hourly rate remains the same. Many young workers start in part-time roles while studying, so understanding the annual equivalent helps when comparing job offers.

It is also important to note that the minimum wage is a legal floor – you cannot be paid less than £10.00 per hour if you are 18 to 20. Some employers offer more, especially in sectors like retail, hospitality, or logistics where competition for staff is high. The ONS ASHE 2025 data shows that median hourly pay for all full-time employees (excluding overtime) was £19.67, more than double the youth minimum wage. This reflects the higher earnings of older, more experienced workers.

How the 18-20 Rate Compares to Other Minimum Wage Rates

The UK has different minimum wage rates depending on age and apprentice status. From 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 under 19, or those 19+ in their first year)

If you are 18, you move into the 18-20 bracket. Once you turn 21, you become eligible for the higher National Living Wage. The gap between the youth rate and the adult rate is narrowing – the 2025 increase for 18-20 year olds was the largest percentage rise (16.3%), compared to 6.7% for the 21+ rate. This reflects a policy push to reduce age-based pay differences.

What the Data Says About Young Workers’ Pay

The ONS Low and High Pay bulletin for 2025 notes that the lowest-earning employees are typically aged 16 to 21 and concentrated in elementary occupations and hospitality. The proportion of low-paid jobs (those earning less than two-thirds of median hourly pay, which was £17.96) fell to just 2.5% in April 2025 – the lowest level since records began in 1997. This suggests that minimum wage increases are lifting many young workers above the low-pay threshold.

However, the ONS also cautions that its ASHE estimates are provisional and based on a 1% sample of PAYE records. The number of jobs paid below the minimum wage is estimated at around 447,000 (1.5% of employee jobs), but this is not a measure of non-compliance because some workers may be legitimately exempt (e.g., those receiving free accommodation).

London Weighting and Other Allowances

If you work in London, your employer may offer a “London weighting” allowance on top of the minimum wage. The Living Wage Foundation’s “real living wage” for London is higher than the statutory minimum (for 2025 it was £13.85 per hour in London, compared to £12.60 outside London). However, these are voluntary rates – employers are only legally required to pay the National Minimum Wage. For an 18-year-old in London, the statutory floor is still £10.00 per hour, but many employers in the capital pay more to attract staff.

Overtime and Holiday Pay

Overtime pay is not always at a higher rate for minimum wage workers – the law only requires that your average hourly pay across the pay reference period does not fall below the minimum wage. If you work extra hours, your total pay must still meet the hourly minimum when averaged. Holiday pay is also a separate entitlement: you should receive at least 5.6 weeks of paid holiday per year, calculated on your normal pay.

How to Use This Information

Whether you are a job seeker comparing offers or an employee checking your payslip, knowing the minimum wage for 18 year old 2025 helps you ensure you are being paid correctly. Use the salary articles on this site for more guidance on negotiating pay, understanding deductions, and planning your finances. You can also explore salary data for specific occupations and regions.

Remember that the conversion from hourly to annual is a rule of thumb – actual take-home pay depends on your exact hours, any unpaid breaks, and whether you receive tips or bonuses. Always check your contract and the official GOV.UK guidance for the most authoritative information.
