Modern Slavery Policy in the UK: When You Need One and What to Include

When you’re running a small business, it can feel like your compliance to-do list never ends.

But modern slavery isn’t a “big business” issue. It can sit quietly inside supply chains, labour providers, subcontracting arrangements and overseas manufacturing - including in industries that small businesses rely on every day.

That’s why more and more SMEs are being asked (by customers, investors, landlords, procurement teams and partners) to show they take modern slavery risks seriously. Often, the first thing they’ll ask for is your modern slavery policy for small business operations.

In this guide, we’ll break down what a modern slavery policy is, when you need one, what to include, and how to actually implement it in a way that protects your business (and isn’t just a “tick-box” document).

What Is A Modern Slavery Policy (And Why Should Small Businesses Care)?

A modern slavery policy is a written document that explains:

• what modern slavery is (in plain English),
• your business’s commitment to preventing it, and
• the steps you’ll take to reduce the risk of modern slavery in your operations and supply chain.

“Modern slavery” is an umbrella term. It commonly covers:

• slavery and servitude,
• forced or compulsory labour, and
• human trafficking.

Even if you’re a small team based in the UK, modern slavery risk can still show up in practical places, such as:

• cleaning, security or maintenance subcontractors,
• agency and temporary labour,
• imported stock or products manufactured overseas,
• IT hardware and equipment supply chains,
• logistics and delivery providers,
• construction and fit-out contractors.

From a business perspective, having a clear modern slavery policy helps you:

• meet customer and tender requirements (many larger organisations require it),
• reduce reputational risk (allegations can escalate quickly),
• prove you have taken reasonable steps if concerns are raised, and
• set expectations internally for staff involved in buying, hiring and supplier management.

It also sits alongside your broader compliance framework - the same way you might use internal policies and procedures to help you comply with what laws apply to your business generally.

Modern Slavery Policy vs Modern Slavery Statement: What’s The Difference?

This is a common sticking point.

A modern slavery policy is an internal-facing (and sometimes public-facing) document explaining your approach, rules and responsibilities.

A modern slavery statement is typically published annually under the Modern Slavery Act 2015 (if you meet the threshold) and focuses on what actions you’ve taken during the financial year to address modern slavery risks.

Small businesses are often not legally required to publish a statement - but may still benefit from (or be asked for) a policy.

When Do Small Businesses Need A Modern Slavery Policy In The UK?

There are two ways to think about “need” here:

• when the law requires related disclosure, and
• when your commercial reality requires it (even if you’re under the legal threshold).

1) Legal Threshold Under The Modern Slavery Act 2015 (Section 54)

Under section 54 of the Modern Slavery Act 2015 (the “transparency in supply chains” provision), certain organisations must publish a modern slavery statement for each financial year.

In broad terms, the duty applies if the organisation:

• supplies goods or services,
• carries on business (or part of a business) in the UK, and
• has a global turnover of £36 million or more.

Most small businesses won’t meet the £36m turnover threshold. So, strictly speaking, you may not be legally required to publish a statement.

However, if you do meet the threshold (now or in future), it’s important to know that a compliant modern slavery statement generally needs to be:

• approved by the board of directors (or equivalent management body),
• signed by a director (or equivalent), and
• published on your website with a prominent link from the homepage (if you have a website).

Even where the annual statement duty does not apply, having a modern slavery policy can still be a smart move (and in many cases, practically unavoidable).

2) Commercial Pressure: Tenders, Clients, Funders And Supply Chain Due Diligence

In practice, small businesses often need a modern slavery policy because:

• you want to win work with larger businesses or public sector bodies (who require it for procurement),
• you’re onboarding with a new enterprise client and they request your policy pack,
• you’re using subcontractors and need a documented approach to reduce risk,
• you’re seeking investment and ESG due diligence is part of the process, or
• you operate in a higher-risk industry (for example, construction, manufacturing, cleaning, agriculture, hospitality, logistics, garment/textile supply chains).

In other words: even if you’re not legally required to publish a modern slavery statement, having a modern slavery policy in place can be essential to grow without getting stuck at compliance gates.

What Should A Modern Slavery Policy For A Small Business Include?

A good policy should be practical, readable, and tailored to how your business actually operates.

If your policy is vague (“we don’t tolerate modern slavery”) but doesn’t explain how you reduce risk, it won’t give you much protection - and sophisticated clients may reject it anyway.

Here’s what we typically recommend including.

1) A Clear Purpose And Scope

Start with a short explanation of what the policy is for and who it applies to, such as:

• directors and senior leadership,
• employees and workers,
• contractors, freelancers and consultants,
• suppliers and subcontractors (where relevant).

Also clarify whether it applies only in the UK or across international sourcing.

2) A Plain-English Definition Of Modern Slavery

Keep this section simple. Your staff should be able to understand the risk without legal training.

You can reference the Modern Slavery Act 2015, but focus on practical meaning - for example, coercion, debt bondage, withholding identity documents, threats, unsafe conditions, and inability to leave work freely.

3) Your Business’s Commitment And “Zero Tolerance” Position

Most policies include a clear statement that your business:

• has a zero-tolerance approach to modern slavery, and
• expects the same from suppliers and subcontractors.

But don’t stop there. Briefly explain how this commitment translates into action (due diligence, training, reporting, supplier requirements).

4) Roles And Responsibilities

This is where small businesses can keep things realistic.

Instead of creating a complex governance structure you’ll never use, assign responsibility clearly, for example:

• Director/Founder: overall accountability and sign-off.
• Operations/Procurement: supplier onboarding checks and contract controls.
• HR/People Lead: recruitment practices and training.
• All Staff: reporting concerns and completing training.

If you have broader policy documents, you can align the modern slavery policy with your Workplace Policy framework so staff understand how it fits together.

5) Risk Assessment: Where Modern Slavery Could Show Up In Your Business

This is one of the most important parts of a modern slavery policy for a small business - because it shows you’ve thought about your actual risk profile.

Depending on your industry, you might cover:

• use of labour providers, recruitment agencies, or umbrella companies,
• use of subcontractors (especially multi-tier subcontracting),
• sourcing from countries/regions with higher reported risks,
• cash-in-hand arrangements (which can hide exploitation),
• unusually low pricing that suggests workers are being underpaid.

You don’t need a 30-page audit. But you do need a sensible process for identifying higher-risk categories and deciding what extra checks apply.

6) Due Diligence On Suppliers And Subcontractors

This section outlines the steps you take to vet suppliers. For small businesses, that might include:

• confirming the supplier is a legitimate entity (e.g. Companies House checks where relevant),
• requiring key compliance confirmations (right to work, minimum wage compliance, safe working conditions),
• requesting the supplier’s own modern slavery policy/statement (if they have one),
• risk-based questionnaires for higher-risk suppliers.

To make this enforceable, many businesses build modern slavery clauses into their supplier contracts and onboarding documents, such as a tailored Supply Agreement or ordering terms.

If you sell goods/services to customers and have standard documents controlling your commercial relationship, it can also help to align supplier expectations with your outward-facing Terms of Trade (especially around subcontracting, compliance, and audit/inspection rights).

7) Ethical Recruitment And Labour Practices

If you hire staff, your policy should cover how you reduce risk in recruitment, including:

• only using reputable recruitment agencies,
• not charging workers recruitment fees (directly or indirectly),
• verifying identity and right-to-work documents properly,
• watching for red flags (e.g. a third party controlling a worker’s documents or pay).

This is also a good time to check that your core people documents (like contracts and onboarding paperwork) are consistent with your policy and don’t create accidental risk.

8) Training And Awareness

A policy that sits in a folder is a risk in itself - because it can look like you wrote something you never implemented.

Set out:

• who gets trained (e.g. procurement staff, managers, HR, anyone engaging contractors),
• how often training happens (e.g. annually, or on induction), and
• what training covers (red flags, reporting lines, how to escalate concerns).

9) Reporting Concerns And Whistleblowing

Your policy should explain how someone can report a concern safely and confidentially.

Small businesses often keep this simple:

• report to a named director/manager,
• report to HR (if applicable),
• an anonymous reporting option (if you can support it), and
• non-retaliation commitment (no one will be penalised for raising genuine concerns).

It’s common to align this with a broader whistleblowing policy (or speak-up procedure) so you’re not reinventing the wheel across multiple documents.

10) What Happens If A Breach Is Suspected Or Confirmed?

This is another area where practical detail matters.

Your policy should outline steps such as:

• internal investigation and documentation,
• suspending engagement with a supplier pending review (if appropriate),
• requiring remedial action from the supplier,
• terminating the contract for serious breaches,
• reporting to relevant authorities where required.

Be careful not to promise steps you can’t realistically follow. It’s better to commit to a clear, workable process than an ambitious one that doesn’t happen in real life.

How To Implement Your Modern Slavery Policy In Practice (Without Overcomplicating It)

Implementation is where many small businesses get stuck - not because they don’t care, but because they’re time-poor and wearing ten hats already.

Here’s a practical approach that tends to work well for SMEs.

Step 1: Map Your Supply Chain (At A Sensible Level)

You don’t need to map every micro-supplier on day one. Start by listing:

• your key suppliers,
• any subcontractors working under your brand, and
• any labour providers or agencies.

Then identify which ones are “higher risk” based on location, industry, labour intensity, and pricing.

Step 2: Add Supplier Onboarding Checks

Create a short onboarding checklist that matches your risk levels. For example:

• low risk: basic business verification and written confirmations
• medium risk: questionnaire + contract clauses
• higher risk: deeper questionnaire, evidence requests, and ongoing review

Where possible, build these into your contracts so you have leverage if something looks wrong.

Step 3: Build Modern Slavery Controls Into Contracts

This is where your legal foundations really matter.

A policy is a statement of intent, but contracts are what you can enforce. A well-drafted agreement can require suppliers to:

• comply with relevant laws,
• maintain records and provide evidence on request,
• notify you of any suspected breaches, and
• allow you to terminate for serious non-compliance.

If you’re regularly engaging suppliers, it’s worth getting tailored help with Contract Drafting so the wording fits your industry and your actual bargaining position.

Step 4: Train The Right People (Not Everyone Needs The Same Depth)

For a small business, a “one size fits all” training program is often unrealistic.

A good compromise is:

• short, general training for all staff (awareness and reporting), and
• more detailed training for anyone involved in recruitment, procurement, or supplier management.

Step 5: Review The Policy Annually (Or When Your Business Changes)

Update your policy if you:

• start importing goods,
• start using labour agencies,
• take on government or enterprise clients,
• expand internationally, or
• enter a higher-risk sector.

Keeping it current helps you respond confidently when a client asks for your latest policy.

Common Mistakes Small Businesses Make With Modern Slavery Policies

A modern slavery policy can be a great risk-management tool - but only if it reflects reality.

Here are some common traps to avoid.

Using A Generic Template That Doesn’t Match Your Operations

Templates often include promises you can’t keep (like routine audits of every supplier worldwide).

If an issue comes up later, those unrealistic commitments can create reputational and contractual risk - because you may be judged against your own published policy.

Confusing A Policy With A Modern Slavery Statement

If you are (or become) legally required to publish an annual statement, you need to ensure it’s compliant with the Modern Slavery Act requirements and approved appropriately.

A policy is helpful, but it doesn’t automatically satisfy the statement obligations.

Not Linking The Policy To Actual Contracting And Procurement

This is a big one.

If your procurement process doesn’t change at all, then your policy may not reduce risk in practice.

Even simple steps - like onboarding checks and contract clauses - can make a big difference.

Not Giving Staff A Safe Way To Report Concerns

If staff or contractors don’t know who to speak to (or worry they’ll get in trouble), issues are less likely to be raised early.

That’s why clear reporting lines and non-retaliation language matter, even for small teams.

Forgetting To Keep Evidence

If a large client asks what you’ve done to reduce modern slavery risk, you’ll want to show:

• supplier onboarding checklists,
• signed contracts with compliance clauses,
• training records, and
• notes of any reviews or investigations.

It doesn’t need to be complex - but it does need to exist.

Key Takeaways

• A modern slavery policy for small business operations sets out your commitment and practical steps to prevent forced labour, trafficking, and exploitation in your business and supply chain.
• Even if you’re under the £36 million turnover threshold for mandatory modern slavery statements, you may still need a policy to satisfy client procurement, tenders, or partner due diligence.
• A strong modern slavery policy should cover scope, responsibilities, risk assessment, supplier due diligence, ethical recruitment, training, reporting, and what happens if a breach is suspected.
• Implementation matters - align your policy with supplier onboarding, contract clauses, and staff training so it’s more than just a document.
• Avoid generic templates that don’t match your operations, and make sure you can realistically follow what your policy promises.
