Check the National Minimum Wage
The right rate by age and apprentice status, with an employer compliance check.
An 18-year-old worker in the UK is entitled to at least £10.85 an hour from 1 April 2026, the National Minimum Wage rate for 18 to 20 year olds, and that rate rose by 8.5% at the start of the 2026-27 tax year, the largest single-year increase of any age band [1] [2]. The figure is a legal floor, not a suggested wage, and it applies to almost every 18-year-old in paid work, whatever the sector or the job title.
There is one important exception that trips up both young workers and the businesses that hire them. An 18-year-old who is an apprentice can be paid the lower apprentice rate of £8.00 an hour, rather than the 18 to 20 rate, in certain circumstances [1] [4]. Knowing which rate applies, and when, is the difference between a compliant payroll and an underpayment that HMRC can pursue.
This article sets out the exact rate an 18-year-old is owed for the 2026-27 tax year, the apprentice exception and how it unwinds, who counts as entitled to the minimum wage, how the hourly rate is tested against actual pay, and the direction the age bands are moving in as the government works towards a single adult rate.
Key takeaways
- The minimum wage for an 18-year-old worker is £10.85 an hour from 1 April 2026, set by the 18 to 20 age band [1] [2].
- An 18-year-old apprentice can instead be paid the apprentice rate of £8.00 an hour, but only while under 19 or in the first year of the apprenticeship [1] [4].
- The 18 to 20 rate rose 8.5% for 2026-27, faster than the 4.1% increase to the adult National Living Wage, as part of a plan to narrow the gap between the bands [2] [3].
- Entitlement depends on being a worker above compulsory school age, not on the contract label, so casual, part-time and zero-hours staff all qualify [4] [10].
- Employers that underpay face a penalty of 200% of the arrears, up to £20,000 per worker, and public naming once arrears pass £500 [8].
The minimum wage for an 18 year old in 2026-27
The National Minimum Wage is a legal minimum hourly rate that nearly every worker in the UK is entitled to, with different rates set by age and for apprentices [1] [5]. An 18-year-old falls into the 18 to 20 age band, which is a distinct rate above the under-18 rate and below the adult National Living Wage [1].
The 18 to 20 rate explained
From 1 April 2026, the 18 to 20 National Minimum Wage is £10.85 an hour, up from £10.00 the year before, an increase of 8.5% [1] [2]. A worker is paid this rate for the whole period they are aged 18, 19 or 20, and moves up only on reaching 21, when the adult National Living Wage applies [1] [4].
The rate takes effect from the start of the first pay reference period that begins on or after 1 April, so a worker's pay must move to the new figure from that point rather than on an anniversary of their start date [7] [6]. An 18-year-old working a 37.5-hour week at £10.85 earns around £406.88 before deductions, against roughly £375 on the previous rate [1].
Where the 18 to 20 band sits among all the rates
The 18 to 20 rate is one of four minimum wage rates, and the full picture matters because a workforce often spans more than one band [1]. The table below shows the rates in force from 1 April 2026 against the rates they replaced [1] [2].
| Category | Rate from 1 April 2026 | Previous rate | Increase |
|---|---|---|---|
| National Living Wage (21 and over) | £12.71 | £12.21 | +4.1% |
| 18 to 20 year olds | £10.85 | £10.00 | +8.5% |
| Under 18 (above school leaving age) | £8.00 | £7.55 | +6.0% |
| Apprentice rate | £8.00 | £7.55 | +6.0% |
The gap between an 18-year-old on £10.85 and a 21-year-old on £12.71 is £1.86 an hour, or about £3,600 a year for full-time hours, which is why the age of a young worker is a live payroll figure rather than a background detail [1] [3]. Accommodation provided to a worker is the only benefit that can count towards the minimum wage, with an offset of £11.10 a day or £77.70 a week from 1 April 2026 [1] [7].
When an 18 year old is paid less: the apprentice rate
The headline rate of £10.85 is not universal for every 18-year-old. An apprentice can lawfully be paid the lower apprentice rate, and this is the single most common reason an 18-year-old is paid below the 18 to 20 figure [1] [4].
The apprentice rate and who it covers
The apprentice rate is £8.00 an hour from 1 April 2026, the same as the under-18 rate [1] [2]. It applies to an apprentice who is either under 19, or 19 and over but in the first year of the current apprenticeship [4] [1]. An 18-year-old apprentice is under 19, so the apprentice rate can apply for the whole time they are 18, regardless of how far they have progressed through the programme [4].
The apprentice must be on a recognised apprenticeship and must be paid for training time that forms part of the apprenticeship, not only for productive hours [6] [7]. Where a young worker is simply learning on the job without a formal apprenticeship agreement, the apprentice rate does not apply and the 18 to 20 rate of £10.85 is the floor [4] [1].
When an apprentice moves to the age rate
The apprentice rate ends in two situations. The first is age: once an apprentice turns 19 and has completed the first year of the apprenticeship, they move to the rate for their age, which for a 19 or 20 year old is the 18 to 20 rate of £10.85 [4] [1]. The second is completion: finishing the apprenticeship moves the worker onto the age-appropriate rate immediately [4].
For an 18-year-old, this means the apprentice rate can run until the day they turn 19, at which point the first-year test becomes relevant [4]. Payroll has to track both the worker's birthday and the apprenticeship anniversary, because a missed uplift on either date is a straightforward underpayment that HMRC can recover with a penalty on top [8] [6]. Businesses running this across several apprentices typically rely on UK payroll software that flags each rate change before the payrun rather than depending on a manual diary note.
Which 18 year olds are entitled to the minimum wage
Entitlement to the minimum wage turns on employment status and age, not on what a contract happens to be called [4]. This matters for 18-year-olds in particular, because much of the work they do is casual, seasonal or part-time, and those arrangements are fully covered [4].
Workers, employees and the compulsory school age
The minimum wage is owed to workers above compulsory school age, a group that is wider than employees alone [4] [10]. It covers full-time and part-time staff, casual and zero-hours workers, agency workers, pieceworkers and commission-only workers, so an 18-year-old on a zero-hours retail contract is entitled to exactly the same hourly floor as one on a salaried contract [4].
Every 18-year-old is above compulsory school age, which a person reaches on the last Friday in June of the school year in which they turn 16 [10] [4]. There is therefore no school-age complication for an 18-year-old: the only live question is whether the 18 to 20 rate or the apprentice rate applies [1] [4].
Who is not entitled
A small number of 18-year-olds fall outside the minimum wage. The genuinely self-employed are not entitled, because they are not workers, though HMRC assesses this on the reality of the arrangement rather than the label the parties use [4] [6]. Company directors without a worker contract, volunteers who receive only reasonable expenses, and people living and working as part of a family in the family business are also outside the scope [4].
These exclusions are narrow and often misapplied. Labelling an 18-year-old as self-employed does not remove the entitlement if the working relationship is in substance one of employment, and HMRC can look through the arrangement to find an underpayment [4] [8]. An employer unsure of a young worker's status should resolve it before setting pay, not after.
How the minimum wage is actually worked out
Paying £10.85 an hour on paper is not the same as meeting the minimum wage. Compliance is tested on average pay over a pay reference period, and certain deductions and payments reduce the figure that counts [7] [11]. This is where an apparently well-paid 18-year-old can slip below the floor without anyone intending it.
The pay reference period
The minimum wage is assessed over a pay reference period, which is the worker's pay cycle and can never be longer than one calendar month [7]. The test is whether total qualifying pay in the period, divided by the hours worked in it, is at least the applicable rate [7] [11].
Because the test is an average, a single low-paid shift does not breach the minimum wage if the period as a whole clears the threshold, and equally a generous basic rate can be dragged below the floor by deductions elsewhere in the period [7]. The hours that count include time the worker is required to be available at or near the workplace, not only active working time, which is a frequent source of error for staff asked to arrive early or stay to lock up [11].
What counts as pay, and what does not
Not every payment to an 18-year-old counts towards the minimum wage, and several common deductions pull the figure down [7] [6]. The table below separates the two [7].
| Counts towards the minimum wage | Does not count, or reduces it |
|---|---|
| Basic pay and salary | Tips and service charges, however paid |
| Bonuses and incentive pay | Overtime and shift premiums (the extra above basic) |
| Commission on the worker's own performance | Deductions for uniforms, tools or equipment |
| Accommodation offset within the daily limit | Deductions for the employer's own benefit |
Tips can never count towards the minimum wage, regardless of how they are distributed, a point that matters in hospitality where many 18-year-olds work [7] [6]. A deduction made for the employer's benefit, such as the cost of a required uniform, reduces minimum-wage pay even if the headline rate looks compliant, so a young worker on exactly £10.85 who is charged for a uniform is likely to be underpaid in that period [7]. Deductions for income tax, National Insurance and genuine pension contributions do not reduce minimum-wage pay, because they are not for the employer's benefit [7]. An employer issuing a compliant HMRC-compliant payslip can show these deductions clearly so the qualifying pay is auditable.
The direction of travel: towards a single adult rate
The 18 to 20 rate is not a fixed feature of the system. The government has asked the Low Pay Commission to narrow the gap between the 18 to 20 rate and the adult National Living Wage, with the stated aim of moving towards a single adult minimum wage over time [3] [9].
This is why the 18 to 20 rate rose 8.5% for 2026-27 while the adult rate rose 4.1%: the younger band is deliberately being lifted faster to close the distance [2] [3]. For employers of young staff, the practical reading is that the premium for hiring an 18-year-old over a 21-year-old is shrinking each year, and workforce-cost planning should assume the gap continues to narrow rather than hold [3] [9]. A young worker's wage is not the whole cost, as a worker under 21 attracts no employer National Insurance up to £50,270, a relief covered in the guide on employer National Insurance. Payroll systems that update rates automatically each April remove the risk of applying a stale figure once the bands shift again [6].
What employers must do to stay compliant
The minimum wage is enforced by HMRC, and the consequences of getting an 18-year-old's rate wrong are financial and reputational [8]. Compliance rests on correct rates, accurate records and clean payslips.
Records and payslips
Employers must keep records sufficient to show that each worker has been paid at least the minimum wage, and those records must be retained for at least six years [8] [6]. A worker has the right to inspect their own minimum-wage records, and a refusal within the statutory window is an offence [8].
Every worker is also entitled to an itemised payslip showing gross pay, net pay and each deduction, and the total hours worked must appear where pay varies by time, which covers most hourly-paid 18-year-olds [6] [7]. Accountants managing this across several employers often use a payroll bureau platform that stores the hours and rate behind every payslip so a minimum-wage check can be produced for any pay reference period on demand.
Penalties and naming
Where HMRC finds an underpayment, it issues a Notice of Underpayment requiring the employer to repay all arrears, and adds a penalty of 200% of the total underpaid, up to a maximum of £20,000 per worker and a minimum of £100 [8]. The penalty is halved if the arrears and half the penalty are paid within 14 days [8].
Beyond the financial penalty, employers whose arrears exceed £500 can be named publicly under the government's naming scheme, which lists the business and the amount owed [8] [4]. For a small business, the reputational cost of appearing on that list often outweighs the arrears themselves, which is why rate accuracy on young and apprentice workers is treated as a compliance priority rather than an administrative nicety [8].
Check an 18 year old's pay against the rate
An employer or worker who wants to confirm that an hourly rate clears the legal floor can test it against the 2026-27 rates with the Moonworkers minimum wage calculator, which applies the correct age-band and apprentice rules to the hours and pay entered.

Conclusion
The minimum wage for an 18-year-old is £10.85 an hour for the 2026-27 tax year, unless the worker is an apprentice, in which case the £8.00 apprentice rate can apply while they remain under 19. The rate itself is simple; the compliance around it is not, because entitlement reaches casual and zero-hours staff, the test runs on average pay across a pay reference period, and ordinary deductions such as a charged-for uniform can quietly push a worker below the line.
The structural change worth watching is the slow convergence of the age bands. As the 18 to 20 rate is lifted faster than the adult rate, the cost advantage of hiring younger staff is narrowing, and employers who plan for a single adult rate rather than a fixed discount will be ready for whatever the bands look like at the next uprating.
Frequently asked questions
How much is the minimum wage for an 18 year old per hour?
An 18-year-old is entitled to at least £10.85 an hour from 1 April 2026, the National Minimum Wage rate for the 18 to 20 age band [1] [2]. This rate applies for the whole time the worker is 18, 19 or 20, and increases to the adult National Living Wage of £12.71 only when they turn 21 [1]. The one exception is an 18-year-old apprentice, who can be paid the £8.00 apprentice rate [4].
Can an 18 year old be paid less than £10.85 an hour?
Lawfully, only if the 18-year-old is an apprentice, in which case the apprentice rate of £8.00 an hour can apply while they are under 19 or in the first year of the apprenticeship [1] [4]. For any other 18-year-old worker, £10.85 is the legal floor, and paying below it is an underpayment that HMRC can recover with a penalty [8]. Deductions for items such as uniforms can also push effective pay below the minimum even when the headline rate looks correct [7].
Does an 18 year old on a zero-hours contract get the minimum wage?
Yes. Minimum wage entitlement depends on being a worker above compulsory school age, not on the type of contract, so casual, part-time, agency and zero-hours workers are all covered [4] [10]. An 18-year-old on a zero-hours contract is therefore entitled to at least £10.85 an hour for every hour worked, including time they are required to be available at the workplace [1] [11].
Why is the minimum wage lower for an 18 year old than for a 21 year old?
The minimum wage uses age bands, and the 18 to 20 rate of £10.85 sits below the adult National Living Wage of £12.71 that applies from age 21 [1]. The gap is narrowing, because the government has asked the Low Pay Commission to close the distance between the bands with the aim of a single adult rate in time, which is why the 18 to 20 rate rose faster than the adult rate for 2026-27 [3] [9]. Until the bands merge, age remains a factor in a young worker's legal minimum pay [1].
