My salary says overtime is included: which checks still matter?

Three separate questions, three separate answers

GOV.UK explains that employers in the United Kingdom do not generally have to pay an overtime premium. However, your average pay for the total hours you work must not fall below the applicable National Minimum Wage. Your employment contract may promise additional overtime pay, and if it does, that promise is a separate contractual question. Working-time requirements, such as limits on weekly hours and rest entitlements, are yet another matter. Signing a working-time opt-out does not, by itself, answer whether your contractual overtime amount has been paid or whether your average pay meets the minimum wage. You need to assess each of these three areas separately.

Read the actual overtime wording in your contract

Keep your salary clause, your normal working hours, any overtime approval rules, and any time-off arrangement. Ask whether additional hours are expected, whether they must be authorised, and whether they are included in your salary or compensated separately. Distinguish a discretionary bonus clause from a promised payment for recorded hours. A manager's statement that everyone stays late is not a calculation and does not explain the contract. Keep written terms and evidence of any agreed verbal terms so that the promise can be checked.

Record your time in a usable form

List required preparation, meetings, normal tasks, and overtime with dates and actual duration. Separate your commute and personal activity from work time that needs assessment. Match your record to payroll periods and pay items. Ask payroll which hours and deductions it uses in its minimum-wage calculation. Do not compare a yearly salary with an isolated difficult week without checking the relevant method. A clear record helps you ask precise questions and lets an adviser see the pattern.

Raise the right issue with the right route

Request the contractual explanation and, where relevant, the minimum-wage calculation, using your records. If the problem concerns excessive hours or rest, identify that separately when seeking advice. Use the appropriate employment or enforcement route for an unresolved issue. This guide helps you frame a query; it does not conclude that every unpaid late finish is unlawful or calculate compensation. You need to match your concern to the correct legal question.

Hypothetical illustration: salary includes undefined overtime

Imagine a worker whose contract says the salary includes overtime, but the contract does not define how many hours are covered. The worker regularly stays 45 minutes late on weekdays. To check the position, the worker should first ask: "Does my contract specify which hours are included in my salary, and does it require overtime to be authorised?" Then the worker should calculate average pay for all hours worked over the relevant pay reference period and ask: "Does my average pay for all hours worked meet the National Minimum Wage?" Finally, if the worker is concerned about weekly hours or rest, the worker should ask: "Do my working hours comply with the working-time limits, and does my opt-out cover the specific limit in question?" These questions show the reasoning; they do not predict the outcome.

Next steps if the issue remains unresolved

If your employer does not provide a clear explanation or calculation, and the issue remains unresolved, you can seek advice from Acas, which offers free and confidential advice on working hours and pay rights. You can also consider the appropriate employment tribunal or enforcement route for your specific claim. When you contact an adviser, bring your contract, your time records, and your pay slips, and explain which question you are asking: contractual overtime pay, minimum wage compliance, or working-time limits. This will help the adviser identify the correct issue. Check the deadline for the particular claim promptly; an internal request does not itself stop that clock.
