How overtime pay works in the UK
There is no legal right to be paid extra for overtime in the UK. Whether you get time and a half, double time or your normal rate depends on your contract or your employer's policy. Some employers give time off in lieu instead.
What the law does say is that your average pay for all the hours you work, including overtime, must not fall below the National Minimum Wage. From 1 April 2026 the National Living Wage for workers aged 21 and over is £12.71 an hour.
Example
At £15 an hour for 37.5 hours, plus 6 hours of overtime at time and a half (£22.50 an hour), you earn £562.50 + £135 = £697.50 for the week, an average of £16.03 an hour. Worked every week, that is £36,270 a year.
Frequently asked questions
How many hours can I be asked to work?
Most workers cannot be made to work more than 48 hours a week on average, usually averaged over 17 weeks. You can choose to opt out of this limit in writing, and you can cancel the opt-out later.
Does overtime count towards holiday pay?
Regular overtime should be included when your holiday pay is worked out for the 4 weeks of leave that come from EU-derived rules. See our holiday entitlement calculator for how much leave you get.
