what are the maximum working hours allowed per week in the UK?

You can't work more than 48 hours a week however you can opt out from this limit. If you are under 18 years old then you can't work more than 8 hours or 40 hours per week.

You may have to work more than 48 hours a week on average if you work in a job:

• where 24-hour staffing is required
• in the armed forces, emergency services or police
• in security and surveillance
• as a domestic servant in a private household
• as a seafarer, sea-fisherman or worker on vessels on inland waterways
• where working time is not measured and you’re in control, eg you’re a managing executive with control over your decisions
