What Is the National Minimum Wage?

How much an employer can pay is not entirely up to them: the law sets a floor on hourly pay for most workers in the UK. The National Minimum Wage is that floor, and understanding it matters whether you are an employee checking your payslip or a business making sure you stay on the right side of the rules. This guide explains how the rates are structured, who is covered, the National Living Wage, and what to do about underpayment. This is general information, not legal advice.

What it is

The National Minimum Wage is the lowest hourly rate that most workers in the UK are legally entitled to be paid. It is set by the government and enforced by HMRC, and paying less than it is against the law. The aim is to protect lower-paid workers from being undercut and to set a baseline that applies across the economy.

Rather than a single figure, the minimum wage is organised into age bands, with the rate rising as workers get older, plus a separate rate for apprentices. The highest band has its own name — the National Living Wage — which sometimes causes confusion, as we explain below.

Crucially, the rates change every year, usually in the spring. Because of that, this guide deliberately avoids quoting specific amounts that would quickly date; the current rates are always published on GOV.UK, and it is worth checking them whenever they are updated.

The National Minimum Wage is a legal floor, not a recommendation. An employer can pay more, but paying an eligible worker less is unlawful and can lead to fines and being publicly named.

How the rates are structured

The system uses different rates depending on circumstances:

• A top rate — the National Living Wage — for workers at or above a set age.
• Lower bands for younger workers, stepping down by age group.
• A separate apprentice rate for eligible apprentices, which can be lower in certain cases.

The reason for age bands is partly to encourage employers to take on younger and less experienced workers. The apprentice rate applies to apprentices under a certain age, or in the first year of their apprenticeship; after that, apprentices usually move on to the rate for their age. For anyone considering this route, our overview of how apprenticeships work sits alongside the pay rules, though the figures themselves live on GOV.UK.

Because the bands and the qualifying ages can change, the safest approach is always to match a worker's age and situation to the current table on GOV.UK.

National Living Wage versus the real Living Wage

This is one of the most common points of confusion, so it is worth being clear:

1. The National Living Wage is the legal top band of the National Minimum Wage. Employers must pay at least this to workers at or above the qualifying age.
2. The real Living Wage is a voluntary higher rate calculated by an independent charity based on the cost of living. Employers choose whether to pay it.

In short, the National Living Wage is compulsory and set by the government, while the real Living Wage is optional and set by a campaign. An employer that signs up to the voluntary scheme pays more than the law requires; one that does not still has to meet the statutory National Living Wage. Mixing the two up can lead people to think they are underpaid when they are not, or vice versa.

Who is and is not covered

Most workers are entitled to the minimum wage, including full-time, part-time, casual and agency staff. However, some are not covered, including:

• The genuinely self-employed, who set their own rates.
• Certain company directors without an employment contract.
• Some family members working in a family business and living in the employer's home.
• Volunteers and certain trainees in specific schemes.

The distinction often comes down to employment status, which can be genuinely tricky — being labelled self-employed does not automatically make it so. If you are unsure where you stand, Acas offers free guidance, and worker status affects far more than pay, including holiday and sick rights such as Statutory Sick Pay.

It is also worth remembering that minimum wage law looks at your average hourly pay over a pay period, after certain deductions. Things like unpaid time spent on duty, deductions for uniforms, or time spent travelling between jobs can all affect whether you are genuinely being paid the minimum, even if your headline rate looks fine.

What to do about underpayment

If you think you are being paid too little:

• Check your average hourly rate, allowing for the hours you actually work and any deductions.
• Raise it with your employer first — underpayment is sometimes a genuine payroll error.
• Complain to HMRC if it is not resolved; HMRC enforces the minimum wage and can order back pay.
• Get free advice from Acas or Citizens Advice if you are unsure of your rights.

Employers who fail to pay can face penalties and be publicly named, so the system has real teeth. For workers and employers alike, the minimum wage interacts with wider payroll obligations — businesses running payroll need to handle it correctly alongside tax and National Insurance through PAYE for employers.

The bottom line

The National Minimum Wage is the lowest hourly pay most UK workers are legally entitled to, organised into age bands with the top band known as the National Living Wage. It is not the same as the voluntary real Living Wage, and the figures change every year, so GOV.UK is the place to check current rates. Most workers are covered, underpayment can be challenged through HMRC, and free help is available from Acas and Citizens Advice. Always work from the latest official figures rather than last year's numbers.
