Baseline response (no ZPI)

No, this is likely not lawful under UK employment law, but it depends on specific circumstances. I'll explain step by step based on relevant regulations, and I strongly recommend consulting a qualified employment lawyer or ACAS (Advisory, Conciliation and Arbitration Service) for advice tailored to your situation, as I'm not providing legal advice here. ### 1. **Key Legal Framework** - **National Living Wage (NLW)**: This is the UK's statutory minimum wage for workers aged 21 and over (as of April 2024, it's £11.44 per hour). Employers must pay at least this for all "qualifying hours" worked. Failure to do so can result in enforcement action by HMRC, including back pay, fines, and naming/shaming. - **National Minimum Wage Act 1998 and Regulations**: These define what counts as "working time" for minimum wage purposes. Time spent working must be paid at least NLW, and deductions or non-payment for working time are unlawful. - **Working Time Regulations 1998 (WTR)**: These regulate rest breaks, maximum hours, and define "working time" more broadly. Travel time can fall under this if it's part of the job. ### 2. **Is Travel Time Between Clients "Working Time"?** - For care workers in domiciliary (home-based) care, travel between client visits is often a core part of the job. Under the WTR: - **Working time** includes any period when a worker is "working, at the employer's disposal, and carrying out their activity or duties." - If workers are required to travel directly from one client to the next (e.g., no freedom to go home or use the time personally), this time is typically **working time**. They are at your disposal and performing job-related duties (traveling to deliver care services). - HMRC guidance (in the Employer Helpbook E13) and case law confirm that travel time **during the working day** (e.g., between assignments) counts as paid time for minimum wage calculations. This applies even if the travel is unpaid in the contract or payslip. - Exceptions: - Travel **to/from the first/last client of the day** (commuting) is generally **not** working time and doesn't need to be paid. - If travel is incidental (e.g., short walks between nearby clients) or if workers are truly free to use the time as they wish (e.g., can run personal errands), it might not count. But 30 minutes suggests structured travel, making it likely working time. - In the care sector specifically, the Low Pay Commission and unions (e.g., UNISON) have highlighted this issue. Many care providers have faced back-pay claims for unpaid travel time, especially post-COVID when scrutiny increased. ### 3. **Why Unpaid Travel Time Violates NLW** - If the 30 minutes is working time, you must include it in the total hours for NLW calculation. Paying only for direct care time (e.g., 1-hour visits) while excluding travel means workers are effectively earning below NLW for the full shift. - Example: Suppose a worker does two 1-hour visits with 30 minutes unpaid travel between them (total 2.5 hours). If you pay for 2 hours at £11.44/hour (£22.88), their effective rate for 2.5 hours is £9.15/hour—below NLW, which is unlawful. - Contracts stating "travel time is unpaid" don't override the law; such clauses are void if they result in underpayment. - Other issues: This could also breach WTR rest break rules (workers need 20 minutes unpaid break after 6 hours, but travel might prevent proper rest). ### 4. **Relevant Case Law and Precedents** - **Addison Lee v. Gascoigne (2010)**: Taxi drivers' travel time between jobs was ruled working time. - Care sector cases (e.g., via employment tribunals) have awarded back pay for unpaid travel, especially where workers couldn't use the time freely. - The 2021 Pimlico Plumbers case (Supreme Court) reinforced that on-call time can be working time if workers aren't free. - Note: The 2014 Tomlinson-Blake case (on sleep-ins) doesn't directly apply here, as travel isn't "sleeping." ### 5. **Consequences of Non-Compliance** - **For workers**: They can claim arrears (up to 6 years back) via HMRC or tribunals. No time limit for NMW claims. - **For employers**: HMRC investigations can lead to: - Repayment of underpaid wages (with interest). - Penalties up to 200% of arrears. - Public naming on the HMRC "name and shame" list. - Employment tribunal claims for unlawful deductions. - In the care sector, this is a hot topic—e.g., the 2023 Care Quality Commission (CQC) guidance emphasizes fair pay, and unions are pushing for reform. ### 6. **What Should You Do?** - **Audit your practices**: Calculate total working hours including travel. Use timesheets or GPS data to track it accurately. - **Update contracts/payslips**: Explicitly include travel time as paid hours. Consider mileage allowances (tax-free up to 45p/mile) to cover costs without affecting NLW. - **Seek advice**: - Contact ACAS (free helpline: 0300 123 1100) for guidance. - Consult an employment solicitor or HR specialist familiar with care services. - Check resources: HMRC's NMW helpline (0300 123 1100) or the Low Pay Commission's annual reports on care workers. - **Best practice**: Many ethical care providers now pay for travel time or offer travel allowances to retain staff and comply with law. The government's 2024 NLW increase adds pressure to get this right. If this is in a different country (e.g., not UK), laws vary—e.g., in the US, FLSA rules on travel time are similar but state-specific. Provide more details for better guidance, but professional legal advice is essential to avoid risks.

Enhanced response (with ZPI)

### Is Unpaid Travel Time Between Client Visits Lawful Under the National Living Wage? No, this practice is likely unlawful in the UK, based on employment law principles. I'll explain the key reasons below, drawing from relevant legislation like the National Minimum Wage Act 1998 (which covers the National Living Wage, or NLW) and the Working Time Regulations 1998. However, **this is not legal advice**. Employment law can be fact-specific, and you should consult an employment lawyer, ACAS (Advisory, Conciliation and Arbitration Service), or HMRC for your situation. Non-compliance can lead to back pay claims, fines up to £20,000 per worker, and reputational damage. #### Key Legal Principles 1. **What Counts as "Working Time" for Wage Purposes?** - The NLW (currently £11.44 per hour for workers aged 21+ as of April 2024) must be paid for **all hours worked**. "Working time" includes any time when a worker is at the employer's disposal and carrying out their duties (per the Working Time Regulations, Regulation 2). - Travel time between client visits for care workers is often classified as working time if: - It's a required part of the job (e.g., workers must go directly from one client to the next without returning to base). - The worker is "on duty" during travel, even if not actively caring for someone—e.g., transporting equipment, reviewing notes, or simply being available for the next visit. - HMRC guidance (in their NMW manual, e.g., NMWM05100+) explicitly states that time spent traveling between work locations (like client homes) during a shift counts as working time, unless it's a personal commute (e.g., from home to the first client). For domiciliary care workers, the 30 minutes between visits typically qualifies as this. 2. **Specific Guidance for Care Workers** - The Department for Business and Trade (DBT) and Skills for Care (the care sector body) have issued guidance confirming that unpaid travel time in home care is a common compliance issue. In 2023, HMRC recovered over £1.5 million in back pay from care providers for similar violations. - If your workers start at one client's home and end at another (without paid travel home), the intervening travel must be paid. Exceptions are rare, such as if travel is incidental and very short (e.g., within the same building), but 30 minutes doesn't qualify. - Case law supports this: In *Walden v Addison Engineering* (2010) and similar rulings, courts have ruled that required inter-site travel is working time. For care, see the European Court of Justice's *Tyco* case (2015), which influenced UK rules by deeming mobile workers' travel as working time. 3. **Consequences of Non-Compliance** - Workers can claim arrears for up to 6 years (3 years in Scotland), plus interest. - You could face HMRC enforcement, naming-and-shaming on public lists, and civil penalties. - If this affects sleep-ins or zero-hour contracts (common in care), additional rules under the NLW apply—e.g., sleep-ins were reclassified in 2020 to require payment for all hours. #### What Should You Do Next? - **Audit Your Practices**: Review payslips, contracts, and rotas. Calculate if travel time pushes effective hourly rates below NLW (e.g., if a 7-hour shift includes 1 hour unpaid travel, the paid 6 hours must cover the full value). - **Seek Official Advice**: - Contact ACAS (acas.org.uk or 0300 123 1100) for free guidance. - Use HMRC's NMW helpline (0300 123 1100) or their online compliance tool. - For care-specific advice, reach out to Skills for Care (skillsforcare.org.uk). - **Best Practices to Comply**: - Include travel time in paid hours or provide a mileage allowance (but allowances don't count toward NLW—base pay must cover it). - Update contracts to clarify paid time. - Consider scheduling to minimize unpaid travel (e.g., cluster visits geographically). If your setup involves self-employed contractors (vs. employees), different rules apply—contractors aren't covered by NLW, but misclassification is a risk. Provide more details about your operations (e.g., employment status, contract types) for more tailored general info, but professional consultation is essential.
