Mobile Workers Working Time Regulations

Mobile workers working time regulations

Understanding mobile workers working time regulations is more important than ever, especially now that so many roles involve travel, off-site duties or flexible working patterns. I speak to employers every week who feel confident managing office hours but feel less certain when staff spend most of their time on the road. Those uncertainties are understandable. The rules around working time become more complicated the moment travel is part of the job.

Although the law has been in place for years, many employers still assume the principles for desk-based staff automatically apply to mobile workers. That is not always true. Tribunals look closely at how time is recorded, how breaks are managed and whether the employer has taken reasonable steps to protect worker wellbeing. Even small gaps in understanding can lead to disputes about pay, fatigue, safety or entitlement to rest periods.

I have seen more than one employer learn the hard way that good intentions are not enough. The key is clarity. When your workers operate across multiple sites, spend long periods driving or have irregular start and finish times, your obligations under mobile workers working time regulations increase. Getting the details right protects both your business and your staff.

Why mobile workers working time regulations matter for employers

Mobile staff often work in ways that do not fit neatly into standard timetables. Travel time, waiting periods, gaps between appointments, long shifts and unpredictable job lengths all complicate working time calculations. Tribunal cases have repeatedly shown that misunderstanding these rules can leave employers vulnerable, even when workers agreed informally to their patterns.

The broad purpose of the Working Time Regulations is to safeguard workers from fatigue, protect health and safety and ensure some predictability in their working patterns. The rules apply to employees, workers, and agency staff, although certain roles have modified arrangements. For mobile workers, the typical question I receive is: when does travel count as working time? And how does that affect rest breaks?

There is no single answer. It depends on the nature of the job. A field engineer attending appointments all day has a different pattern from a care worker travelling between client homes, or a sales representative covering a region. Even so, employers must take reasonable steps to make sure these workers receive proper rest and are not working excessively long days without recovery periods.

To get a sense of how legal duties fit together more broadly, many employers find it helpful to look at EBS Law’s guidance on HR employment law, which explains the regulatory framework that supports safe and fair working practices.

Understanding working time for mobile employees

Working time includes any period during which the worker is performing duties, carrying out tasks, being trained or required to remain available to the employer. For mobile workers, this can include travel between appointments, depending on the specifics of the role. Where the employee has no fixed workplace, travel from home to the first customer may be classed as working time.

I once advised a facilities company whose engineers were driving three hours to their first job each day. The employer had always treated this as unpaid travel. When an engineer raised it as a working time issue, the company realised they had never reviewed their practices in light of mobile workers working time regulations. Once we looked at the nature of the role, it became clear the engineers had no fixed site and the travel should have been included in their working time calculations.

These details matter because they influence whether staff exceed the 48-hour weekly limit, whether breaks are taken at the right intervals and whether night work rules apply. All of these can lead to claims if not handled properly.

Common questions employers ask me include:

• Does travel between jobs count as working time?
• When should rest breaks be taken during long journeys?
• How do on-call periods work when staff are mobile?

The best way to avoid misunderstandings is to be transparent. Agree expectations, explain how time is recorded and make sure staff know when they are entitled to a break. If you are not sure whether your arrangements comply, it may help to compare them to your broader workplace policies. For instance, EBS Law’s article on managing remote employees discusses different working environments and the need to adapt expectations where workers are not supervised directly.

Breaks, rest periods and night working under mobile workers working time regulations

One of the most misunderstood areas is rest. Workers must have:

• an uninterrupted 20-minute break if their working day exceeds six hours
• 11 hours’ rest in each 24-hour period
• 24 hours of uninterrupted rest each week (or 48 hours over a 14-day period)

For mobile workers, these breaks still apply. The difficulty is ensuring they are taken. When a worker spends long periods driving, employers sometimes forget the legal requirements because the day feels less structured than traditional office work.

Night work also requires special attention. A mobile employee who travels late into the evening may fall within the definition of a night worker, depending on their schedule. Night workers are subject to additional limits and must be offered free health assessments. Employers often overlook this obligation.

If you are unsure whether someone qualifies as a night worker, a good starting point is to review your internal procedures. EBS Law’s guidance on employee grievance procedures also highlights the importance of making decisions that are clearly documented. The same principle applies here: clear processes reduce disputes.

Record-keeping obligations for mobile workers

Working time records must be accurate. Employers sometimes assume mobile workers will track their hours themselves. That is risky. You have a legal obligation to keep enough information to demonstrate compliance with the law.

Some employers use vehicle tracking systems, time-logging apps or cloud-based tools. Others rely on daily worksheets. The method is less important than the consistency. If a tribunal examines your records, it will want to see that staff hours were monitored sensibly, that breaks were encouraged and that excessive working patterns were addressed.

On multiple occasions I have advised employers whose mobile teams were regularly exceeding safe hours without anyone realising. Once time was monitored properly, patterns emerged quickly. Workers were not complaining, but the legal risk increased every week. Having a system in place protects you and ensures your workers stay safe. For more detail on the employer’s general obligations around working practices, the guide to contracts of employment and rules can help frame the wider responsibilities.

Managing fatigue, safety and employer liability

Fatigue is a significant risk for mobile workers. Long journeys, irregular hours and demanding schedules can leave workers exhausted without them realising it. Employers must take steps to manage this, particularly when employees drive for work. Health and safety obligations still apply. If fatigue contributes to an accident, the employer may face liability.

Training managers to recognise fatigue, encouraging proper rest and monitoring schedules helps reduce risk. The laws do not expect employers to be perfect, but they do expect you to take reasonable steps to keep people safe.

When mobile staff raise concerns about workload, scheduling or excessive travel, it is important to respond fairly. Concerns might appear minor at first, but if ignored they may escalate into grievances or stress claims. Clear communication and a willingness to adjust unreasonable patterns often resolve issues quickly. The article on resolving workplace disputes explains how early intervention prevents small problems from escalating into formal complaints.

Flexible working requests and mobile employees

The rise in flexible working has affected mobile roles too. Workers may request changes to routes, hours or travel expectations. Employers must consider flexible working requests reasonably and respond within statutory timeframes.

Some employers worry that agreeing to one request will create a precedent. That is not automatically true. You simply need a clear and evidence-based explanation for your decision. If a mobile worker’s request conflicts with business needs, you can refuse, but your reasoning must fall within legitimate grounds. EBS Law’s page on the flexible working rules for employers helps clarify how to handle these requests lawfully.

Adapting your policies to stay compliant

The biggest mistake I see is relying on outdated policies. Many were written before remote and mobile working became standard. You should review your policies to ensure they reflect reality. That might include:

• updating travel time and rest break rules
• clarifying start and finish times
• adding guidance on driving safety and fatigue
• setting expectations for time recording

Even small updates can make your processes more defensible. If your organisation has grown quickly, changes to your workforce pattern or client base may mean your existing practices no longer align with your legal duties. Reviewing contracts and employee handbooks can help bring consistency across your business. When in doubt, tailored employment law advice for employers can save significant time and reduce the risk of claims.
