Work Reference Letters in the UK: What Employers Can and Can’t Say

If you run a small business, there’s a good chance you’ll be asked to provide a work reference letter at some point - whether it’s for an employee who’s leaving on good terms, someone you dismissed, or even an employee who’s still working for you but applying for a rental property or a volunteer role.

It sounds simple. But references can create legal risk if they’re inaccurate, unfair, or disclose information you shouldn’t be sharing.

The good news is: you can provide helpful, professional references without putting your business in a difficult spot. The key is having a clear process, knowing what you can and can’t say, and sticking to a consistent format.

In this guide, we’ll walk you through how work reference letters work in the UK, what to include, what to avoid, and a practical template you can adapt for your business.

Do Employers Have To Provide A Work Reference Letter In The UK?

In most UK private-sector situations, there’s no general legal duty to provide a reference for a former employee.

That said, there are a few important exceptions and practical realities to be aware of:

When You Might Need To Provide A Reference

• Contractual commitments - some businesses promise references in settlement terms, exit agreements, or even in an Employment Contract.
• Regulated industries - some sectors have specific rules or standard practices around references (for example, in financial services, certain roles may require regulatory references under FCA/PRA regimes).
• Company policy and consistency - if you regularly provide references, refusing one without a good reason can look inconsistent and may inflame disputes.

Even if you’re not required to provide a reference, many businesses choose to give at least a basic factual reference as standard. It helps maintain goodwill and avoids unnecessary conflict.

If you’re unsure whether you can decline a request, it’s worth sense-checking your approach against guidance on providing a reference and what risks can arise if your decision appears unfair or inconsistent.

What Can (and Can’t) You Say In A Work Reference Letter?

When you give a work reference letter, the safest overall approach is:

• keep it true
• keep it fair
• keep it relevant
• keep it consistent (across employees and managers)

Let’s break down the key legal and practical limits.

You Can Give A Factual Reference

A factual reference is usually the lowest-risk option, and many SMEs adopt it as a policy. It typically includes:

• job title
• dates of employment
• brief description of duties (optional)
• sometimes: final salary (only if necessary and justified)
• sometimes: reason for leaving (only if you’re confident it’s accurate and appropriate to disclose)

If you want a simple format to standardise internally, using a factual reference style can reduce the risk of disputes about subjective opinions.

You Can Give An Opinion (But It Must Be Supportable)

You can include performance-based comments (for example, “reliable”, “strong attention to detail”, “good with customers”). However, the legal risk increases when you move into opinions.

If you provide opinion, it should be:

• based on evidence (appraisals, KPIs, documented feedback)
• balanced (avoid exaggeration)
• consistent with your records (disciplinary notes, performance reviews)

One common problem for small businesses is that managers write “glowing” references informally, then later the business is challenged because internal records show performance issues. A consistent HR process (and documentation) is what protects you here.

You Can’t Give A Misleading Or Negligent Reference

Even though you may not be legally required to provide a reference, once you do provide one, you typically owe a duty to take reasonable care that it is:

• accurate
• not misleading overall
• fair in overall impression

This is where businesses can get caught out - especially if someone is dismissed for serious misconduct and a reference implies everything was fine.

There isn’t a single “one size fits all” rule for how much you must disclose. Whether leaving something out could make a reference misleading depends on the context and what you have chosen to say. If you’re dealing with a sensitive exit, it’s worth getting advice before you send anything.

You Can’t Discriminate In A Reference

A reference should not include comments that could be discriminatory or suggest a decision was influenced by a protected characteristic under the Equality Act 2010 (for example, age, disability, pregnancy/maternity, religion, sex, race).

Even well-meaning remarks can cause issues. For example, mentioning someone’s health, pregnancy, or “family commitments” is rarely necessary and can create legal risk.

If the request is asking for health-related information (which is common in some roles), treat it carefully and consider what you can lawfully disclose. As a general rule, an employee’s medical details are sensitive, and there are strict rules around handling them. This overlaps with the wider question of medical information at work and when it’s appropriate to share it.

You Can’t Breach Confidentiality Or Data Protection

References almost always involve personal data, so UK GDPR and the Data Protection Act 2018 are relevant.

In practical terms, this means you should:

• only share information that is necessary for the purpose
• make sure it is accurate and up to date
• limit who in your business can issue references
• keep a record of what was provided (so you can evidence it later)

Also be mindful of confidential business information in the reference itself (for example, internal processes, client lists, commercial terms). Data protection is one angle, but confidentiality is another - and mishandling it can become an employment dispute in its own right. If you’re setting expectations internally, a clear approach to confidentiality at work helps keep your team aligned on what should never go into a reference.

How To Manage Reference Requests As A Small Business (A Practical Process)

References tend to land on your desk at busy times. The easiest way to stay compliant (and keep them low-effort) is to set up a simple, repeatable process.

Step 1: Decide Your Reference Policy

Most SMEs choose one of these approaches:

• Factual references only (recommended for lower risk)
• Factual + limited performance comment (for example, “met expectations”)
• Full character and performance references (higher risk; requires strong HR records)

Whatever you choose, aim to apply it consistently. Inconsistency is what often triggers arguments (“you gave them a reference, why not me?”).

Step 2: Limit Who Can Issue A Reference

You’ll reduce risk if references come from one controlled channel, such as:

• a director
• HR (if you have it)
• one nominated manager trained on your policy

This avoids different managers giving different “styles” of reference (and accidentally disclosing things they shouldn’t).

Step 3: Verify The Request

Before you provide a work reference letter, check:

• who is requesting it (company/organisation name and contact details)
• whether the employee has consented (many forms include a consent statement)
• what format they want (letter, email, online form)

Also consider whether you’re comfortable sending it by email and whether any specific wording is required.

Step 4: Cross-Check Your Records

Before you hit send, confirm:

• dates of employment (start/end)
• job title (and whether it changed)
• any agreed wording (for example, settlement agreement reference clause)
• whether there were disciplinary issues that make a “glowing” reference inaccurate

This step is crucial. A reference that doesn’t match your records is one of the most common ways employers get into trouble.

How To Write A Work Reference Letter (With A Template You Can Use)

A strong work reference letter is clear, brief, and sticks to information you can support.

Below is a practical structure you can use in your business. It’s designed to be easy to apply and easy to defend if it’s ever questioned.

What To Include In A Work Reference Letter

• Your business letterhead (or company name and address)
• Date
• The recipient’s name/company (if known) or “To Whom It May Concern”
• Employee’s full name
• Job title(s) and employment dates
• Brief duties summary (optional)
• Performance comments (optional, only if supportable)
• Reason for leaving (optional, only if appropriate)
• A short disclaimer/limitation (common and sensible)
• Your name, role, and contact details

Work Reference Letter Template (UK)

Note: This template is a general starting point. You should tailor it to the circumstances, and take extra care where there were performance, conduct, or health issues.

Dear  / To Whom It May Concern,

Re: Reference For 

I am writing to confirm that  was employed by  from  to  as .

In this role,  was responsible for .

During their employment,  .

.”]

This reference is given in good faith and is based on information held by  at the date of writing. It is provided for the purpose of  only, and (to the extent permitted by law) we do not accept responsibility to any person other than the addressee for any reliance placed on it for any other purpose.

If you require any further information, please contact me at .

Yours sincerely,

Should You Add A Disclaimer?

Many employers include a short disclaimer clarifying the purpose of the reference and who it is addressed to. A disclaimer won’t remove your obligation to be accurate and fair, but it can help manage how the reference is used (for example, preventing it being reused in a different context without your knowledge).

What If You’re Asked For A “Character Reference”?

Character references can be riskier because they rely on personal opinion. If you do provide one, keep it tightly connected to the workplace (for example, honesty in handling cash, punctuality, teamwork) and avoid comments about private life or personal circumstances.

If you’d prefer a structured format, using an employee reference template approach can keep things consistent across your team.

Common Risk Scenarios (And How To Handle Them Safely)

Some reference requests are straightforward. Others come with a bit of history - and that’s where businesses often need to slow down.

1. The Employee Was Dismissed For Poor Performance

If performance management is documented and the dismissal was handled fairly, you generally shouldn’t provide a reference that suggests the opposite.

Common “safe” approaches include:

• provide a factual reference only, without performance commentary
• if asked directly, provide a carefully worded, accurate statement that can be supported by records

Avoid emotionally loaded phrases (“hopeless”, “lazy”, “couldn’t do anything right”). They add heat, not value - and increase legal risk.

2. The Employee Was Dismissed For Misconduct

This is high risk. If you give a reference that is too positive, you could face arguments that you misled the recipient. If you give a reference that is too negative (or inaccurate), you could face disputes from the former employee.

Often, the best option is a strictly factual reference. Depending on your policy (and the wording you can genuinely support), you may also be able to give a neutral statement about eligibility for rehire.

Also be careful about confidential details. For example, if the misconduct involved sharing confidential information, you still shouldn’t publish sensitive details that aren’t necessary for the purpose of the reference. (This overlaps with broader employment risk issues, like confidentiality mistakes at work.)

3. The Request Asks About Sickness, Disability, Or Adjustments

This is a common tricky one. Health data is sensitive under UK GDPR, and Equality Act issues can arise if the reference includes information that leads to discrimination.

As a starting point:

• don’t volunteer health information unless it’s clearly necessary and you have a lawful basis
• avoid speculation (“we think they had anxiety”)
• if the recipient needs health-related checks (for a role with specific requirements), consider taking advice before responding

4. You’re Asked For A Reference But There’s An Ongoing Dispute

If there’s an ongoing grievance, tribunal claim, or settlement negotiations, you need to be particularly careful. A reference may become part of the dispute later.

In many cases, a mutually agreed form of words can be the most practical solution.

If you want to protect your business, this is a good time to get legal input rather than guessing.

Key Takeaways

• A work reference letter isn’t always legally required, but once you provide one, it should be accurate, fair, and not misleading.
• A factual reference (job title + dates + limited duties) is usually the lowest-risk option for small businesses.
• Avoid including sensitive personal information (especially health-related details) unless it’s clearly necessary and lawful to share.
• References should be consistent with your internal records - misalignment between a reference and performance/disciplinary history is a common risk area.
• Set a simple internal process: limit who can issue references, verify requests, and keep a copy of what you provided.
• If the employee left in difficult circumstances (misconduct, performance dismissal, ongoing dispute), it’s worth getting tailored advice before responding.
