What are the maximum hours I can be expected to work over an average working day?

Those workers covered by the Working Time Regulations must not be required, against their wishes, to work an average of more than 48 hours a week over a rolling reference period of 17 weeks, or more than 13 hours in any one day. There are some exceptions to the formula for calculating the reference period for certain industries and occupations, and where the employer agrees a collective agreement or workforce agreement with employee representatives. Workers may agree in writing to work more than the 48 hours average, and can withdraw their agreement at any time.

There are different rules for mobile transport workers and tighter rules for young workers aged 16 and 17.
