Working Time Regulations


The Working Time Regulations 1998 came into force on 1 October 1998 and been amended in part by the Working Time Regulations 1999 and the Working Time (Amendment) Regulations 2003.

    • You can choose to work more than 48 hours a week on average if you’re over 18. This is called ‘opting out’.
    • Your employer can ask you to opt out, but you can’t be sacked or treated unfairly for refusing to do so.
    • You can opt out for a certain period or indefinitely. It must be voluntary and in writing.
