Can an Employer Give a Bad Reference? The UK Rules

"Just say I was rubbish" is not a reference policy

A reference request lands in your inbox for a former employee you were glad to see the back of, and the real question in your head is: can you give a bad reference, and should you? Part of you wants to be honest. Part of you remembers a vague warning that bad references are "not allowed". So you freeze, or worse, you fire off a quick comment you have not really thought through.

Here is the good news: you are allowed to give an honest reference, even a negative one. The catch is that there are rules, and an off-the-cuff comment is exactly where small businesses get caught out.

Let us make this simple and practical.

Quick Answer Box

• Do this: decide on a reference policy, keep references factual and accurate, and apply the same approach to everyone.
• Avoid this: off-the-cuff verbal comments, opinions you cannot back up, and anything that gives an unfair overall impression.
• Write down: who is allowed to give references, what you will and will not include, and the evidence behind anything negative.

Do you have to give a reference at all?

In most cases, no. There is generally no legal duty on an employer to provide a reference. That surprises a lot of people, but it is why so many companies give only a short, factual reference, or sometimes none at all.

There are exceptions. Some regulated sectors, such as parts of financial services, require a reference in a particular form. If you work in one of those areas, the rules are stricter, so check your sector before you set a policy. For most small businesses, though, the choice is yours.

The practical takeaway: you are not obliged to write a glowing reference for someone who did not earn it. You are also not obliged to write a damning one. You get to decide your approach, as long as you apply it fairly.

What can an employer legally say in a reference?

If you do give a reference, the law expects it to be handled with care. The established principle is that a reference must be:

• True
• Accurate
• Fair
• Not misleading as an overall impression

That last point matters. You can technically include only true facts and still mislead, for example by mentioning a single complaint while leaving out the context that it was investigated and dismissed. The overall picture has to be fair, not just each individual line.

Crucially, you owe a duty of care to two people at once:

• The former employee, who could be harmed by an unfair or inaccurate reference.
• The new employer, who is relying on what you say to make a hiring decision.

Get it wrong in either direction and you can be exposed. Talk someone up who is genuinely unsafe in the role, and the recipient may have a claim. Run someone down unfairly, and the former employee may have one.

Can you give a bad reference?

Yes. A negative reference is lawful if it is accurate, fair and can be substantiated. "Substantiated" is the word to hold onto. If you say someone had performance issues, you should be able to point to the reviews, the records, the conversations. If you say attendance was poor, you should have the absence data.

What you must not do is dress up opinion as fact, or let a personality clash leak into what is supposed to be a professional assessment. As ACAS explains in its guidance on giving references, a reference should be based on fact and given in good faith.

The danger zone for small businesses is the casual, emotional response. The manager who picks up the phone, gets asked about a difficult leaver, and vents. That is where accuracy goes out of the window and risk walks in.

Where it goes wrong: the risk routes

If a reference is inaccurate, unfair or misleading, a former employee may have more than one way to bring a claim:

• Negligence, if a careless reference causes them loss, such as a withdrawn job offer.
• Defamation, if it contains untrue statements that damage their reputation.
• Discrimination or victimisation, if a reference is worse because of a protected characteristic, or because the person previously raised a complaint or claim. The Equality Act 2010 protects people from being treated badly for having done so, and that protection can extend beyond the end of employment.

That last one catches people out. If an employee raised a grievance or a tribunal claim and then gets a noticeably colder reference, it can look like payback, even if that was not the intention.

The off-the-cuff verbal reference trap

The single most common mistake we see in small businesses is the unscripted phone call. Someone rings up, a manager who was not expecting it answers honestly, and three sentences later they have said something they cannot evidence and there is no record of what was said.

A verbal reference carries exactly the same duty of care as a written one. The difference is you have no proof of what came out of your mouth, and neither does the person who gave it. If a dispute follows, that is a weak place to be standing.

The fix is a rule everyone follows: reference requests go to one named person, and anything beyond confirming dates and job title is put in writing.

Why a short factual reference is often the smart choice

Plenty of well-run businesses give only a short factual reference. It confirms:

• Job title
• Dates of employment

That is it. It sounds blunt, but it has real advantages:

• It is consistent, so no one can argue they were treated worse than the last leaver.
• It is accurate and easy to evidence.
• It removes the temptation to editorialise.

If a recipient pushes for more, you can politely explain that it is your company policy to give factual references only. That is a perfectly respectable answer, and it protects everyone.

This is the same instinct that protects you when you make a job offer in the first place. A clear process beats a warm improvisation, which is why we always recommend confirming the key terms in writing, as we cover in our guide to whether a verbal offer of employment is contractual in the UK.

What to do if you receive a bad reference about a candidate?

The flip side: you are hiring, and a reference comes back with something concerning. Do not panic, and do not assume the worst.

• Check the facts first. Mismatched dates are often an admin error at the old employer, not a lie. Verify before you confront anyone.
• Separate fact from opinion. "Missed sales targets" is a fact you can weigh. "Lacked enthusiasm" is an opinion that might say more about the referee than the candidate.
• Give the candidate a chance to respond. A short call to talk it through is fair, and often clears things up.
• Make conditional offers. Word offers so they are subject to satisfactory references. That way, if a genuine problem emerges before they start, you have room to act.

A blank or sparse reference is not, by itself, a red flag. As above, many employers simply have a policy of giving minimal references. Ask the referee about their policy before reading anything into it.

A short script for the awkward phone call

If someone rings asking for a reference you would rather not give in full:

> "Thanks for calling. Our policy is to confirm references in writing, and we provide factual information, so job title and dates of employment. If you send your request by email, I will get that confirmed for you."

That is polite, professional and entirely defensible. It also buys you time to check your records rather than reacting in the moment.

What to write down?

For your reference process, document:

• Your reference policy: factual only, or fuller references, and who decides.
• The single named person or role authorised to give references.
• A simple template for the factual reference you will give.
• A rule that nothing substantive is given verbally; it goes in writing.

For any reference that includes negative information, keep:

• The specific facts stated.
• The evidence behind each point: reviews, records, dates, investigation outcomes.
• A note that it was checked for fairness and overall impression before it was sent.

If you ever cannot point to the evidence behind a line, that line should not be in the reference.

Common mistakes

• Treating "you cannot give a bad reference" as the rule. You can, if it is accurate and fair.
• Letting any manager answer reference calls off the cuff.
• Mixing personal feelings into a professional assessment.
• Giving a noticeably worse reference to someone who raised a grievance or claim.
• Leaving out context so that true facts still create a misleading picture.
• Having no policy at all, so every reference is improvised.

The bottom line

You can give an honest reference, including a negative one, as long as it is true, accurate, fair and something you can back up. The real risk is rarely the considered written reference. It is the careless verbal one, the unfair dig, or the reference that quietly punishes someone for speaking up.

A simple policy fixes most of this: factual references only, one person responsible, nothing significant said out loud without a written record. If a dispute ever follows a difficult exit, knowing exactly how to accompany and document that process matters too, which is why it is worth understanding who can accompany an employee at a disciplinary meeting before you get there.

If your reference process is currently "whoever picks up the phone says whatever feels right", that is exactly the sort of gap we look for in an HR Health Check, or we can talk it through on a quick discovery call. Better a five-minute policy now than a claim later.
