48-Hour Working Time Opt-Out

Last updated: 2 October 2026.

RMB Stripouts LTD works with subcontractors rather than employing site workers. This page explains the voluntary opt-out from the average 48-hour working week under the Working Time Regulations 1998. Reading this page does not create an opt-out agreement.

Voluntary written agreement

Where the weekly limit applies, an adult worker may choose to agree in writing to work more than 48 hours a week on average. Choosing whether to opt out is voluntary, and a worker must not be treated unfairly for refusing. A genuinely self-employed subcontractor may have different rights; the actual working arrangement matters, not just the label used. Some types of work cannot use an opt-out, and other working time protections still apply.

Ending an opt-out

A worker may cancel a written opt-out at any time by giving written notice to the party with whom they made the agreement. The law requires at least seven days’ notice; a written agreement may set a longer period, up to three months.

Subcontractor arrangements

Subcontracting businesses are responsible for managing the working time of people they employ or engage and for any written opt-out agreements that apply. Contact us if project scheduling raises a working time concern. An opt-out is not required to browse this website or make an enquiry.
