Mobile Workers in the UK: Key Legal Requirements

Do you run a team that’s constantly on the move - field engineers, home carers, delivery drivers, sales reps, merchandisers or surveyors? Mobile workers can be a huge asset, helping you serve customers faster and cover a wider area.

But with a mobile workforce comes a different legal toolkit. From working time and travel pay to lone-working safety and GPS tracking, there are a few rules you need to nail early so your business stays compliant and protected from day one.

In this guide, we walk through the key UK legal requirements for mobile workers, plus the practical contracts and policies to have in place so your team can work safely and efficiently on the road.

What Do We Mean By “Mobile Workers”?

“Mobile workers” are employees or workers whose jobs require regular travel away from a fixed base. They don’t spend most of their day at your office, shop or warehouse - instead, they travel between clients, sites or territories to do the job.

Typical examples include:

• Home and domiciliary care workers visiting multiple service users
• Field service technicians, plumbers, electricians and maintenance teams
• Sales representatives, merchandisers and account managers
• Non-HGV delivery drivers and couriers
• Surveyors, assessors and consultants doing site visits

Mobile work cuts across industries, so there isn’t a single “mobile workers law.” Instead, you need to apply general employment law, health and safety duties and data protection rules to the way your team works on the move.

Which UK Laws Apply To Mobile Workers?

You’ll want to focus on a few core areas when employing mobile workers. Here are the big ones to have on your radar:

• Working time and rest. The Working Time Regulations 1998 (WTR) set rules for maximum weekly hours, daily and weekly rest, and rest breaks. They also govern night work and record-keeping. If your team drives or works late, tracking hours properly is essential. For a refresher on limits and break entitlements, see Working Time Rules.
• National Minimum Wage (NMW). You must pay at least the NMW/NLW for all working time. For mobile workers, what counts as “working time” can include travel between assignments - more on that below.
• Health and safety. The Health and Safety at Work etc. Act 1974 requires you to take reasonably practicable steps to keep workers safe, including when they work alone or off-site. That means suitable risk assessments, training, incident reporting and monitoring.
• Data protection and tracking. If you use GPS, vehicle telematics, dashcams or mobile apps to manage your team, you’ll need a lawful basis for processing under UK GDPR and the Data Protection Act 2018, plus clear transparency and safeguards.
• Driving for work. While HGV/PSV drivers follow separate “mobile workers” rules in transport, all staff who drive for work should be competent, insured and not exceeding safe hours. You should have a driving for work policy and check licences, insurance and vehicle roadworthiness.
• Expenses and deductions. Set clear rules on reimbursable mileage, fuel, parking, tolls and overnight costs. If you ever make deductions (for example, for damage to kit), make sure they’re lawful and agreed in writing. The legal basics are covered in Wage Deductions.

The bottom line: the same legal duties apply, but the way you implement them needs to fit a mobile environment. A little planning goes a long way.

Travel Time, Pay And Working Hours

This is where many businesses unintentionally slip up. For mobile workers, time spent travelling between jobs in a day can count as “working time” under the WTR, and it often counts toward NMW calculations, too.

When Does Travel Time Count?

Broadly, time travelling between assignments during the day is working time. This is especially relevant for “peripatetic workers” - staff with no fixed place of work who move from site to site (think care workers or field service teams). There’s helpful detail in our guide to Travel Time For Peripatetic Workers.

Key points to keep in mind:

• Commute vs. job-to-job. Ordinary commuting from home to a permanent workplace and back is not working time. By contrast, travel between client sites during the working day usually is.
• Start/end of day for peripatetic roles. If your mobile team doesn’t have a fixed base and travels from home to the first job and from the last job home, those journeys can form part of working time in some circumstances. Check your specific arrangements and keep good records.
• Waiting time that’s an intrinsic part of the job - for example, waiting on-site for access - can also count as working time.

Minimum Wage And Mobile Workers

NMW/NLW compliance hinges on accurate recording of what counts as working time. If job-to-job travel or certain waiting time applies, it may need to be included in your pay calculations.

Practical tips:

• Use simple timesheets or an app that records start/end times, site-to-site travel and breaks.
• Set a clear expenses policy so employees aren’t out of pocket for work-related travel and you avoid “wage deduction” issues.
• Regularly audit pay for typical mobile routes to check you remain above NMW/NLW after accounting for working time.

Mileage, Fuel And Vehicle Costs

Decide early how you’ll handle transport:

• Company vehicles with fuel cards or reimbursement of fuel (you should set rules on personal use, storage, repairs and reporting).
• Private vehicles using mileage claims - align rates with HMRC Approved Mileage Allowance Payments (AMAPs) and require receipts/records.

Where you reimburse fuel separately, it’s helpful to be familiar with Employee Fuel Pay, including record-keeping and avoiding unintended tax issues.

Breaks And Night Work

Mobile roles can involve early starts, late finishes and long drives. Under the WTR, most adult workers must have at least a 20-minute uninterrupted break if they work more than six hours, and minimum daily/weekly rest periods. Where night work is involved, you’ll need health assessments and stricter average hour limits. If your routes commonly push the limits, revisit rosters and staffing to stay compliant.

Health And Safety For Lone And Mobile Workers

Health and safety obligations don’t stop at your front door. As an employer, you must assess and manage risks your people face while working alone, at client premises or on the road.

Core Duties And Risk Assessments

Start with a risk assessment that identifies the specific hazards for your mobile roles and sets out controls. Typical risks include driving fatigue, manual handling of equipment, working at height, slips/trips at unfamiliar sites, aggressive customers and emergency situations while lone working.

Your plan should cover:

• Eligibility to drive for work and licence/insurance checks
• Vehicle maintenance schedules, tyres and load safety
• Route planning, realistic scheduling and time for breaks
• Personal safety measures for lone workers (check-in procedures, escalation, duress apps or alarms)
• Manual handling training and suitable equipment (trolleys, PPE)
• Client-site rules (induction, hazard notices, permits to work where relevant)
• Incident reporting and post-incident support

If you’re building out your safety framework, it can help to step back and map it all in one place. A short review against your Health And Safety obligations is a good way to spot gaps before you scale the team.

Lone-Working Procedures

Practical lone-working measures don’t need to be complex. Many small businesses use a simple combination of:

• Pre-visit risk checks and “no-go” criteria (e.g. lack of safe access)
• A check-in/check-out app or scheduled SMS/phone check-ins
• Escalation rules if someone misses a check-in
• Clear guidance on when to walk away from unsafe jobs

Give your team permission to prioritise safety and provide an easy way to report concerns. That culture matters as much as the paper policy.

Data, Devices And Tracking: GDPR Essentials

Most mobile teams rely on technology - mobile apps for job dispatch, GPS for routing and proof-of-attendance, photos or notes captured on phones, and sometimes telematics/dashcams in vehicles. That means personal data is being processed, and in some cases, staff are being monitored.

Your Legal Duties Under UK GDPR

Under UK GDPR and the Data Protection Act 2018, you must have a lawful basis to process personal data, be transparent (tell people what you collect and why), minimise data, secure it appropriately and respect rights such as access and deletion. Monitoring (like GPS tracking or call recording) needs special care because it can be intrusive - consider a Data Protection Impact Assessment (DPIA) to weigh necessity and proportionality.

At a minimum, you should have a clear Privacy Policy that covers any tracking or monitoring, how long you keep data and who you share it with. If external vendors process data for you, make sure you have GDPR-compliant Data Processing terms in place.

Work Phones, BYOD And App Access

Decide whether you’ll issue work devices or allow BYOD (bring your own device). BYOD can save costs but increases risk around data leakage, offboarding and support. If your team uses personal devices, use mobile device management (MDM) where possible, restrict access to business data and set clear rules on backups, photos and messaging apps.

We break down common pitfalls and practical safeguards in Work Phones vs BYOD, including consent, monitoring transparency and access controls.

Vehicle Telematics And CCTV/Dashcams

If you use telematics or dashcams, explain the purpose (for example, safety, routing, incident investigation), when recording occurs, how long data is retained and who can view it. Avoid function creep - don’t start using tracking data to monitor productivity unless you’ve told people and it’s necessary and proportionate. Make sure any audio recording is justified and switched off unless you have a clear legal basis and notice.

Contracts, Policies And Practical Documents

Once you know your operational model, get your contracts and policies set up properly. Good paperwork gives you clarity on pay, expenses, hours and safety - and helps you prevent disputes.

Employment Contracts And Status

Begin with a clear, tailored Employment Contract for each role, covering pay structure, working hours, overtime, travel expectations, place of work, expenses, use of vehicles and equipment, confidentiality and data protection. If you engage self-employed contractors, use a robust Contractor Agreement and make sure the reality of the relationship aligns with the written terms to avoid misclassification risk.

Expenses And Mileage Policy

Put your reimbursement rules in writing. Specify approved mileage rates, what counts as business mileage, types of reimbursable expenses (fuel, parking, tolls, overnight stays), receipt requirements, claim deadlines and approval workflows. Make it easy for staff to comply and for finance to audit.

Working Time And Rostering

Include a working time policy that sets out how hours are recorded, how breaks will be taken during mobile routes, night work safeguards, and any opt-out process for the 48-hour weekly limit. Consider scheduling tools that automatically build legal break windows into routes.

Driving For Work And Lone-Working Policies

Two practical policies to adopt:

• Driving for work. Licence checks, vehicle standards, mobile phone use, speed and parking fines, accident reporting, fatigue management, drug and alcohol rules, and what to do after an incident.
• Lone-working. Risk assessment responsibilities, safe entry/exit criteria, check-in cadence, escalation and emergency procedures.

If you need to recoup costs (e.g. a fine paid by the company card), ensure any recovery is lawful and clearly authorised in the contract. The rules on when deductions are allowed are explained in Wage Deductions.

Data Protection, Monitoring And Acceptable Use

Document how you handle data captured by apps, telematics and photos. Useful components include:

• A staff-facing privacy notice that explains what you collect and why
• An IT/acceptable use policy covering devices, apps, passwords and reporting loss
• A monitoring policy describing GPS tracking, dashcams or call recording, with retention and access controls
• GDPR-compliant supplier contracts and a simple process for handling subject access requests

If you’re setting up from scratch, a short consultation to scope your GDPR Package can save you time and help you implement the right mix of policy, contracts and notices proportionate to your business.

Training And Practical Induction

A policy on paper is only half the story. Build a short induction covering route planning, safe driving, check-ins, incident reporting, manual handling, customer conduct and how to use any apps or devices. Refresher training for night work or higher-risk roles (e.g. roof access, confined spaces) should be scheduled and recorded.

Record-Keeping And Audits

Finally, keep basic records that show you’re walking the talk:

• Timesheets or app logs and break records
• Mileage and expenses with receipts
• Licence and insurance checks
• Vehicle maintenance and incident reports
• Risk assessments and training records
• DPIAs (where relevant) and policy acceptance records

A light, regular audit (quarterly works well) helps you spot trends - e.g. routes that consistently eat into breaks - before they become compliance issues.

Key Takeaways

• Mobile workers bring unique compliance responsibilities - plan for working time, travel pay, safety and data protection from day one.
• Travel between jobs in a day often counts as working time and can impact NMW/NLW compliance. Put simple time and travel recording in place and review typical routes.
• Set clear rules on mileage, fuel and expenses, and only make deductions where lawful and agreed in writing.
• Meet your health and safety duties with practical risk assessments, lone-working procedures, safe driving rules and easy incident reporting.
• If you use GPS, telematics or BYOD, make sure your Privacy Policy, monitoring notices and supplier contracts are UK GDPR-compliant.
• Back everything up with tailored contracts and policies - an Employment Contract, working time and expenses policies, driving for work, lone working, and clear device/tracking rules.
• Keep it practical: short training, simple tools for logging time/expenses, and regular checks will keep your mobile team safe, efficient and compliant.
