Internship Agreements in the UK: What To Include

Bringing interns into your business can be a smart way to build a future talent pipeline, trial new roles and get fresh perspectives on projects.

But there’s a catch: the legal rules around internships in the UK are stricter than many businesses realise. Get it wrong and you could face minimum wage claims, tax issues or reputational damage.

With a clear, well-structured internship agreement and the right policies around it, you can run a compliant, valuable programme that benefits both your business and your interns.

What Is An Internship Agreement (And Why Do You Need One)?

An internship agreement is the written contract that sets out the terms on which an intern joins your business. It clarifies the intern’s legal status, what they’ll do day-to-day, how long the placement lasts, who supervises them, what they’ll be paid (if anything), and the rules they must follow.

From your perspective, it’s about protection and clarity. A well-drafted Internship Agreement helps you:

• Define the intern’s status (to avoid accidental employment)
• Address pay, expenses, and benefits transparently
• Protect confidential information and intellectual property
• Tie the intern into your policies (health & safety, IT, data protection)
• Set learning objectives and supervision so the placement has genuine training value
• Set a fixed term with a simple early termination process if it’s not working out

In short, an internship agreement reduces the risk of disputes and compliance issues, and it sets expectations clearly from day one.

When Is An Intern A “Worker” Or Employee (And What Should You Pay)?

The big legal risk with internships is accidentally creating a “worker” relationship. Under the National Minimum Wage Act 1998, most workers must be paid at least the National Minimum Wage (NMW), plus holiday pay accrual and other protections. Whether someone is a worker depends on what happens in practice, not just what the agreement says.

Your intern is likely to be a worker if they:

• Do productive work for your benefit (not just shadowing or learning)
• Must turn up at set times and personally perform tasks as directed
• Are integrated into your team rota and deliverables
• Lack a genuine “learning first” structure (i.e., the role looks like a junior job)

If those factors are present, pay NMW at a minimum and treat them more like a junior hire with an Employment Contract. If the internship is genuinely about learning, shadowing and observation with no obligation to perform productive work, you may be able to host an unpaid placement-but proceed carefully.

To reduce risk, build your programme around training objectives and supervision, limit the length, keep hours flexible and avoid using interns to cover core business output. For a deeper dive into what counts as lawful unpaid work, it’s worth reviewing how UK law treats unpaid work.

Key UK Laws To Comply With When Hosting Interns

Even if an intern isn’t classed as a worker, several UK laws still apply to your programme. Build your internship around these principles to stay compliant.

Minimum Wage And Holiday

If your intern is a worker, pay at least the NMW (rates vary by age) and ensure they accrue statutory holiday. If they’re not a worker, you can still offer a stipend or reimburse reasonable expenses to support access and inclusion-but be careful that a stipend doesn’t mask a worker relationship in substance.

Working Time And Rest

Where interns are workers, the Working Time Regulations 1998 apply: typical rules around working hours, rest breaks and night work. It’s best practice to follow sensible limits even for non-workers, especially where interns are young or new to a professional environment. If you need a refresher, skim the practical overview of working time rules.

Equality, Diversity And Inclusion

The Equality Act 2010 bans discrimination across protected characteristics throughout recruitment, onboarding and the internship itself. Make sure job ads, selection criteria and day-to-day treatment are fair and accessible, with reasonable adjustments where appropriate.

Health & Safety

You owe a duty of care under the Health and Safety at Work etc. Act 1974. That means risk assessments, safe systems of work, suitable equipment and training-especially if interns enter a workshop, warehouse or client site. It’s good discipline to fold interns into your broader health and safety approach, including inductions.

Right To Work

Before the internship starts, complete right to work checks (Immigration, Asylum and Nationality Act 2006). International students or graduates may have visa conditions limiting hours or the type of work-respect those limits.

Data Protection And Confidentiality

If interns access personal data (e.g., customer details), UK GDPR and the Data Protection Act 2018 apply. Provide data protection training, limit access to what’s necessary, and ensure your public-facing Privacy Policy and internal procedures reflect how interns will handle data.

Confidentiality and IP clauses in the internship agreement are a must. For sensitive projects, consider a short Non-Disclosure Agreement at onboarding.

What To Include In A UK Internship Agreement

A clear agreement helps you deliver a genuinely educational experience while keeping risk low. Build in the following key clauses.

1) Status, Term And Scope

• Role and purpose: A short description emphasising learning objectives and supervision
• Status: Whether they’re a volunteer, worker or employee; avoid language that suggests a job if it’s a training placement
• Term: Fixed start and end date, with the ability to end early on short notice if needed
• Location and hybrid arrangements: State where the intern will work and any remote working expectations

2) Pay, Expenses And Benefits

• Pay: Confirm NMW if they’re a worker; if not, state that the placement is unpaid
• Expenses: Outline what’s reimbursable (e.g., travel, lunch for offsite events), approval process and receipts
• Hours: Typical weekly schedule and flexibility, plus maximum limits for safety and fairness

3) Supervision, Learning And Feedback

• Mentor/supervisor name and contact
• Learning objectives and tasks aligned to development
• Mid-point and end-of-placement feedback

4) Policies And Conduct

• Link the intern to key policies: health and safety, equality, IT/acceptable use, social media, data protection
• Professional standards: Behaviour, dress code, safeguarding where relevant
• Reporting issues: Who to contact for concerns or incidents

It’s tidy to maintain these in your Staff Handbook and reference them in the agreement so you can update the policies without amending the contract.

5) Confidential Information And IP

• Confidentiality: Obligations to protect your business information during and after the internship
• Intellectual property: Assign IP created in the course of the internship to your business
• Return of property: Laptops, passes and files handed back at the end

6) Data Protection

• Access rules: Limit access to personal data to what’s necessary
• Security: Follow your data policies and training requirements
• Breach reporting: Process for promptly escalating incidents

7) Termination

• Short notice termination for underperformance, misconduct or business need
• Immediate termination for serious misconduct or breach of confidentiality

8) Other Practical Points

• References: Whether you’ll provide a basic confirmation of dates afterward
• Conflicts of interest: Declare other commitments that may clash
• Limitation of tasks: State any prohibited duties (e.g., unsupervised client advice, operating certain machinery)

How To Set Up A Compliant Internship Programme (Step-By-Step)

Step 1: Design The Learning Experience

Start with the educational goals. What skills should the intern build? Which team members will they shadow? Identify projects that genuinely teach, not just output you need covered. This is crucial to avoid a worker relationship if you plan an unpaid placement.

Step 2: Decide Status And Pay

Assess whether the intern will be doing productive work. If yes, treat them as a worker and pay NMW. If not, keep tasks focused on learning and observation, keep hours flexible and set a clear time limit.

To avoid confusion across your organisation, document your approach in your Workplace Policy suite so hiring managers follow the same rules.

Step 3: Draft The Internship Agreement

Cover the key clauses outlined above. If you’re engaging a work-shadowing intern and not paying NMW, your wording needs to be precise about status and scope. Don’t rely on generic templates-drafting these agreements properly will save headaches later.

Step 4: Prepare Onboarding And Policies

Issue policy links, provide safety and data protection training, set up limited IT access and schedule supervisor check-ins. If the intern will touch personal data or client files, ensure your Privacy Policy and internal data rules cover their activities.

Step 5: Monitor And Support

Give clear instructions, regular feedback and appropriate supervision. If the intern begins to take on productive output, reassess status and pay promptly to avoid underpayment risk.

Step 6: Wrap-Up Properly

Hold an exit meeting, collect equipment, confirm confidentiality obligations and IP ownership, and consider offering a short reference letter. A positive close-out is great for your employer brand and future hires.

Common Mistakes (And How To Avoid Them)

Internship compliance often goes wrong in predictable ways. Here are the pitfalls to sidestep.

• Using interns to fill staff shortages: If they’re doing the job of a junior team member, they’re likely workers-pay NMW and use an Employment Contract.
• Vague scope and no learning plan: Without clear learning objectives and supervision, unpaid internships look like disguised work.
• “Expenses-only” roles that mask pay: Covering “expenses” at a level that functions as wages is a red flag.
• No IP or confidentiality protection: Interns often see sensitive information-make sure your agreement and, where needed, an NDA are in place.
• Ignoring working time and breaks: Apply sensible limits and follow the Working Time Regulations where interns are workers.
• Overlooking safeguarding: For under 18s, double down on supervision, risk assessment and parental consent as appropriate.

Internship Agreement Vs Employment Contract: What’s The Difference?

An internship agreement is designed for short-term, learning-first placements. It typically limits duties, emphasises training and includes early termination on short notice. There may be no pay if the intern isn’t a worker (with careful design and documentation) or NMW if they are.

An employment contract is appropriate when the person is doing productive work for your business as part of your normal operations. It addresses pay, holiday, sick pay, grievance and disciplinary processes, and other entitlements expected by workers and employees. If in doubt, err on the side of paying NMW and issuing a proper Employment Contract.

If your programme sits somewhere in between (for example, a structured longer-term placement as part of a course), align your documentation carefully and consider the practical checklist in our guide to work experience placements.

Should You Use A Template Or Get A Tailored Internship Agreement?

It’s tempting to copy a template, but internship risk hinges on fine detail-especially around status, supervision, IP and pay. Two internships in the same business can be legally different depending on what the intern actually does.

A tailored agreement drafted for your programme will reflect your training plan, your policies and how your teams work in practice. It should also play nicely with your Staff Handbook and any existing contracts, so there’s no accidental conflict.

If you want to move quickly but stay compliant, consider getting the key documents done properly once and then reusing them with small tweaks for each intake. That way, you build a consistent, low-risk programme you can scale.

Key Takeaways

• Decide upfront whether the intern will do productive work; if they will, treat them as a worker and pay at least NMW.
• Use a clear, tailored Internship Agreement to set status, scope, supervision, pay/expenses, confidentiality, IP and termination.
• Fold interns into your policies from day one-health and safety, equality, IT and data-ideally via a central Staff Handbook.
• If interns handle personal data, make sure your Privacy Policy, training and access controls meet UK GDPR standards.
• Apply sensible limits on hours and breaks and follow the Working Time Regulations where interns are workers.
• Avoid generic templates-small wording differences can change legal status. Getting your documentation right early protects your business and your interns.
