When should a small business use an independent investigator?

Most small businesses try to handle workplace investigations themselves. Someone senior gets asked to look into a complaint, they speak to a few people, write something up, and a decision gets made.

It works until it doesn't.

The problem isn't usually that the decision was wrong. It's that the process wouldn't survive scrutiny. The person investigating had too much context. They sit three desks away from the person being complained about. They'd already formed a view before the first interview. Or the person who ran the investigation also chaired the hearing, which means there was no separation between fact-finding and decision-making.

Tribunals don't just look at what you decided. They look at how you got there.

Where it tends to go wrong

Three scenarios come up over and over again.

The complaint involves someone senior. Maybe the MD, maybe a director. There's nobody internally who can investigate without it feeling political. Staff know who signs off their bonus. That changes what people are willing to say in an interview.

The complaint is about the person who'd normally handle it. In a small business, that's often the same person. The manager who'd usually investigate is the one being complained about. You can't ask someone to investigate themselves and call it fair.

There's no one with the experience to do it properly. Running a workplace investigation isn't just having a few conversations. It means scoping terms of reference, conducting structured interviews, weighing evidence, and producing a report that sets out findings against each allegation. Most managers haven't done that before. And the first time they try shouldn't be the time it matters most.

What "independent" actually means

An independent investigator is someone from outside the organisation with no relationship to anyone involved. They don't report to anyone in the business. They're not trying to protect anyone's reputation. They're there to establish the facts.

That independence matters for two reasons. It gives the employee raising the complaint confidence that they'll be heard fairly. And it gives the employer a defensible process if the outcome is challenged. An employment tribunal will look more favourably on an investigation conducted by someone with no skin in the game.

It's not just investigations

Independence matters at every stage. The person chairing the disciplinary or grievance hearing shouldn't have been involved in the investigation. And whoever hears the appeal shouldn't have been involved in either.

For a business with 20 or 50 people, that's often impossible to do internally. You run out of people who aren't connected to the situation. That's where bringing someone in from outside makes the difference.

What it actually costs

Less than getting it wrong. A straightforward investigation with a few witnesses and a clear allegation might take a few days. A complex one with multiple complainants, safeguarding elements, or senior individuals involved will take longer.

Either way, it's a fraction of the cost of defending a tribunal claim where the process is picked apart. And it's a fraction of the cost of losing a good employee because they didn't trust the process enough to raise the issue in the first place.

Who this is for

I work with small and growing businesses across Sheffield, Leeds, Manchester, Bradford, Hull, Liverpool, Nottingham and Derby. Most of the organisations I support don't have an internal HR team, or they have one person who's too close to the situation to run it themselves. I provide independent workplace investigations, disciplinary and grievance hearings, and appeals for businesses that need someone from outside to make sure the process is done properly.

When to pick up the phone

If you've received a complaint and you're not sure who should handle it, that's usually the sign. If the complaint involves someone senior, if the normal person to deal with it is conflicted, or if nobody in the business has done this before, it's worth having a conversation before you start a process you can't undo.
