When is Unpaid Work Legal in the UK?

In Short

  • Unpaid work is legal in the UK only under specific conditions, such as voluntary roles for charities or community organisations, school work experience for students aged 16–18, and internships that are part of higher education courses lasting up to one year.

  • Interns and volunteers must not perform tasks that would otherwise be carried out by paid employees. If they do, they may be entitled to the National Minimum Wage.

  • Employers should avoid misclassifying workers as volunteers or interns to bypass wage laws, as this can lead to legal challenges and potential penalties.

Tips for Businesses

Ensure that any unpaid work arrangements are genuinely voluntary and comply with legal requirements. Clearly define the nature of the role, tasks involved, and duration to avoid misclassification. Regularly review and update your policies to align with current employment laws and best practices. Consult with legal professionals to navigate complex situations and maintain compliance.

As an employer, navigating the complex landscape of UK employment law is crucial. One area that often raises questions is the legality of unpaid work. While the UK has strict regulations to protect workers’ rights, there are specific circumstances under which unpaid work is permissible. Understanding these exceptions is not just important; it is empowering, allowing you to stay compliant and avoid legal issues. This article outlines different situations where unpaid work is legal in the UK. 

UK employment laws aim to protect workers and ensure fair treatment. The national minimum wage legislation requires employers to pay workers a minimum hourly rate. However, there are exceptions to this rule where unpaid work is allowed.

Voluntary Work

Voluntary work is one of the most common forms of legal unpaid work. Volunteers often donate their time to charities, non-profit organisations, and community projects without expecting pay. To be considered voluntary, individuals must freely offer their services without obligation. You should not pay volunteers, but you may reimburse them for reasonable expenses. 

Work Experience and Internships 

Work experience placements and internships can also be legally unpaid, but specific conditions must be met. For example: 

  • School work experience: Students aged 16-18 who participate in work experience as part of their education can legally work without pay. These short-term placements provide students with exposure to the working world.
  • Higher education internships: Internships that are part of a higher education course can be unpaid if arranged through the educational institution and are, at most, one year long. These internships offer students practical experience related to their field of study. 
  • Voluntary internships: Interns who choose to work for an organisation without expecting payment or a contract implying employment can legally work unpaid. However, if interns perform tasks paid employees would otherwise do, or if regular work is expected, they may be entitled to the National Minimum Wage. 

Work Shadowing

Work shadowing is another situation where unpaid work may be legal. This involves observing professionals performing their duties and giving insights into specific job roles without actively participating. Since work shadowing does not include actual work or contribute to business operations, it is not considered employment and does not require payment.

Voluntary Workers in Specific Sectors 

Specific sectors like sports and arts often have voluntary workers who participate out of passion. These individuals are not under contract, and their involvement is entirely voluntary. However, their role must not resemble an employment relationship with an expectation of regular, structured work. 

Job Trials and Recruitment Processes 

Job trials are a grey area in employment law. A short, unpaid trial period can be legal if it genuinely assesses the candidate’s suitability for the role and is agreed upon by both parties. However, these trials should be brief, and the tasks should be limited to what is necessary for evaluation. Extended trials or those involving productive work that benefits your business should be paid.

Voluntary Agreements 

Sometimes, individuals might enter voluntary agreements to work without pay, especially in family businesses or startups with limited resources. While these agreements can be legal, they must be voluntary, without coercion or expectation of future payment. 

To avoid misunderstandings, it is wise to have an explicit, written agreement outlining the voluntary nature of the work.

Compliance and Best Practices 

Ensuring compliance with employment laws is crucial to avoiding legal issues and maintaining a fair working environment. It is important that you regularly review any unpaid work arrangements at your business and ensure that you are complying with employment laws. Aside from this, some practices that you should aim to implement include: 

  • Clear communication: It is essential to always communicate with your volunteers, interns, and work experience students about the nature of their role and the absence of financial compensation. This practice prevents misunderstandings and ensures a transparent working relationship. 
  • Written agreements: Have written agreements that outline the terms of unpaid work, ensuring that all parties understand their rights and obligations. You should use volunteer or internship agreements to clarify the nature of your relationship but avoid contractual language.
  • Limit unpaid work: Keep unpaid work periods short and ensure they genuinely benefit the individual, such as providing educational or career development opportunities.

Key Takeaways

In general, unpaid work is only legal when it is:

  • voluntary with no employment contract;
  • does not involve any form of payment beyond reimbursing costs; and
  • free of any obligation to perform work. 

If your unpaid work arrangement mirrors an employment relationship, it may be unlawful. Understanding when unpaid work is permissible and implementing best practices can create valuable opportunities for volunteers and interns, fostering a positive and mutually beneficial environment.

Frequently Asked Questions

Can I ask my employees to work unpaid overtime?

No, requiring employees to work unpaid overtime is not permissible unless they are specifically exempt under the law. Employees should be paid for all hours worked, including overtime, in accordance with their employment contract and the National Minimum Wage. Any unpaid work must meet specific criteria, such as being a voluntary role or part of an internship programme.

How can I ensure my internship programme complies with employment laws?

To ensure compliance, your internship programme must provide clear guidelines that the role is genuinely educational and not replacing a paid position. Interns should be given a structured learning opportunity, with no expectation of performing tasks typically done by employees. If the internship involves substantial work, the intern may be entitled to the National Minimum Wage, depending on their age and status. Always check current employment laws for the latest regulations.
