The National Minimum Wage Regulations 1999 (SI 1999/584) were passed as a statutory instrument under the National Minimum Wage Act 1998 to specify various detailed points about how to calculate whether someone is being paid the minimum wage, who gets it, and how to enforce it.

Regulations 3 to 6 define four different types of work that people do.

• r 3, time work
• r 4, salaried work
• r 5, output work
• r 6, unmeasured work

• r 15(1) ‘time work includes time when a worker is available at or near a place of work, other than his home, for the purpose of doing time work, and is required to be available for such work except that, in relations to a worker who by arrangement sleeps at or near a place of work, time during the hours he is permitted to sleep shall only be treated as being time work when the worker is awake for the purpose of working.’
• r 15(1A) a worker who is given suitable sleeping facilities is not doing work when not ‘awake for the purpose of working’.
