Understanding the Minimum Wage for 18 Year Olds

If you're an 18-year-old entering the workforce or comparing job offers, knowing the minimum wage for 18 year olds is essential. In the UK, the National Minimum Wage (NMW) sets the legal floor for pay based on your age. From April 2026, the rate for workers aged 18 to 20 rises to £10.85 per hour – an 8.5% increase from the previous £10.00 rate. This change follows recommendations by the Low Pay Commission and aims to bring younger workers closer to the National Living Wage over time [GOV.UK, National Minimum Wage rates].

For context, the National Living Wage (for those aged 21 and over) will be £12.71 per hour from April 2026. The gap means an 18-year-old working full-time earns roughly £1.86 less per hour than a colleague aged 21 doing the same job. However, the NMW for 18-20 year olds has seen larger percentage increases in recent years to narrow that difference.

Converting Hourly Rates to Annual Salary

When comparing hourly jobs with salaried offers, the standard conversion used across UK payroll and many salary articles is:

Annual salary ≈ hourly rate × hours worked per week × 52 weeks

For the minimum wage for 18 year olds (£10.85 per hour), let's assume a typical full-time contract of 37.5 hours per week (common in many sectors like retail, hospitality, and administration). The calculation is:

£10.85 × 37.5 × 52 = £21,157.50 per year (gross)

This is the gross annual figure before tax and National Insurance. Your take-home pay will be lower once deductions are applied. Remember that this conversion assumes you work every week of the year with no unpaid leave, and that your hours are stable. If you work different weekly hours – say 30 hours part-time – simply adjust the formula:

£10.85 × 30 × 52 = £16,926 per year (gross)

How the Minimum Wage for 18 Year Olds Compares to UK Benchmarks

The Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) for April 2025 shows that the median hourly pay for all full-time employees was £19.67, and median full-time annual earnings were £39,039 [ONS, Employee earnings in the UK: 2025]. This means the minimum wage for an 18-year-old is just over half the median hourly rate. While many employers pay above the minimum, especially in sectors like retail and hospitality, entry-level roles often start at or near the NMW.

It's also worth noting that the NMW for 18 year olds is higher than the apprentice rate (£8.00 per hour) and the under-18 rate (£8.00 per hour). If you are 18 and working as an apprentice in your first year, you are entitled to the apprentice rate, not the 18-20 rate – a key distinction to check in your contract.

Overtime, London Weighting and Other Factors

The figures above are for standard hours. If you work overtime, you should be paid at least your normal hourly rate (or more, depending on your contract). There is no legal requirement for a premium rate for overtime beyond the National Minimum Wage, but many employers offer time-and-a-half or double time.

London weighting is not part of the statutory minimum wage; the NMW applies nationally. However, some London-based employers pay a supplementary allowance to help with higher living costs. If you're considering a role in London, factor in that your actual hourly rate may be higher than the minimum if the employer offers a London weighting premium.

Using the Minimum Wage to Evaluate Job Offers

When you receive a job offer, always check the hourly rate – even for salaried roles. Some employers advertise an annual salary that implies a certain hourly rate. To compare, divide the annual salary by (hours per week × 52). For example, a salaried role offering £22,000 for 37.5 hours per week works out at £22,000 ÷ (37.5 × 52) = £11.28 per hour – above the minimum wage for 18 year olds.

Be aware that not all hours are paid equally. Some salaried contracts may include unpaid breaks or require you to work additional hours without extra pay. Always read the contract terms.

Key Takeaways

• The minimum wage for 18 year olds from April 2026 is £10.85 per hour (for ages 18-20).

• The median full-time annual salary in the UK is £39,039 – about 1.8 times higher.
• The rate for under-18s is £8.00 per hour, and the apprentice rate is also £8.00.
• Always convert hourly to annual using hours × 52, and check if your role includes London weighting or overtime premiums.
