Why probation periods matter more than ever before

Advice from an HR consultant in Ipswich on why probation periods matter more under the new 6-month unfair dismissal rules and how to get your process right.

The rules around unfair dismissal are changing from 1 January 2027.

For small business owners, the shift is significant. The window you've had to manage new starters informally is about to shrink dramatically.

If your probation process isn't tight, you could find yourself exposed before you even realise there's a problem.

As an HR consultant, I'm already helping businesses prepare. Here's what you need to know and what to do about it.

What's actually changing with unfair dismissal

Right now, an employee needs two years of continuous service before they can bring an unfair dismissal claim. That's given employers a generous amount of breathing room when it comes to managing people who aren't working out.

From 1 January 2027, that two-year qualifying period drops to just six months.

On top of that, the statutory cap on unfair dismissal compensation is being removed entirely. So if you get a dismissal wrong after that six-month point, the financial consequences could be far greater than anything you'd face today.

It's also worth remembering that certain claims, like those relating to discrimination or whistleblowing, are already day-1 rights. Those haven't changed. But the addition of much earlier unfair dismissal protection means the overall risk profile for employers has gone up considerably.

Probation hasn't become pointless. It's become essential.

I've heard a few business owners say something along the lines of: "If someone can claim unfair dismissal after six months, and probation only lasts six months anyway, what's the point?"

It's a fair question. But the answer is the opposite of what you'd expect.

Probation is now the only structured period you have to properly assess a new hire, raise concerns, and make a decision about their future with you. All of that needs to happen before they hit six months of service and gain full protection.

Under the old rules, you could afford to be a bit loose with this. A vague probation clause in the contract, a casual chat at the three-month mark, and if things didn't work out after six months you still had another 18 months of runway before any real legal risk kicked in.

That safety net is disappearing. If you haven't made a clear decision about someone before they reach six months, you'll need a fair reason, a documented process, and a much higher standard of evidence to let them go. The cost of delay has gone up enormously.

What a strong probation process actually looks like

A clause in your employment contract that mentions a probation period is a starting point, but on its own it does very little to protect you.

What matters is the process behind it. Here's what that needs to include:

• Clear expectations from day one. A proper job description, short-term goals, and a training plan so the employee knows exactly what's expected of them.

• Regular review meetings throughout the probation period. Not a single conversation at the end. Structured check-ins at set intervals so you can track progress and flag issues early.

• Written feedback when concerns come up. If something isn't right, put it in writing. Be honest and specific about what needs to change.

• A real chance for the employee to improve. Before you make any decision, the person needs to have been given a genuine opportunity to address the concerns you've raised.

• A formal written outcome. Whether they pass, have their probation extended, or don't continue, confirm it in writing.

Each of these steps builds a paper trail. That trail is your protection if anyone ever questions the decision you made.

Why shorter probation periods can work better

This might seem counterintuitive, but there's a strong argument for cutting your probation period down to three months instead of the traditional six.

A shorter timeframe forces earlier action. Managers can't keep putting off difficult conversations when there's a clear deadline approaching. Problems get spotted and dealt with sooner.

And you still have time on your side. If probation ends at three months and you allow a limited extension of, say, one month for borderline cases, you're still making your decision well before the six-month qualifying period arrives.

The danger with a six-month probation is that decisions get left until the very end. By that point, the employee may already have full protection, and your options become much more limited. Making the call at month three or four gives you a buffer that could save you a lot of trouble.

Your managers need to be ready for this

The best probation policy in the world won't help you if the people running it aren't equipped to do so.

Most probation problems I see don't actually start with the employee. They start with a manager who avoided a conversation, assumed things would improve on their own, or simply didn't understand how much the rules had changed.

Your managers are the ones conducting reviews, giving feedback, and ultimately deciding whether someone stays or goes. If they're not trained on what a proper probation process looks like under the new rules, you're leaving yourself open to risk.

Investing in manager training now, before January 2027, is one of the most practical things you can do. It's far cheaper than dealing with the fallout of a poorly handled dismissal.

Some questions worth asking yourself

Before the new rules take effect, it's worth taking an honest look at where you stand:

• Do your managers know how to conduct a structured probation review and document it properly?

• Is your current probation period the right length, or could a shorter one push you towards earlier decisions?

• If a new starter raised a concern about how their probation was handled, would your records hold up?

• Are your employment contracts and probation clauses backed by a real, documented process?

If you're unsure on any of those, now is the time to sort it out. HR consultancy services in Ipswich can help you answer every one of them with confidence.

Getting the right support in place

I know this feels like a lot to get right, especially when you're already busy running a business.

But the changes coming in January 2027 are real, and the cost of being unprepared could be substantial.

As an outsourced HR consultant in Ipswich, I can review your current probation process, tighten up your documentation, and make sure your managers are confident handling those first few months with any new starter.
