How much does it cost to get an employment tribunal wrong?

Most small business owners don't think about employment tribunals until they're facing one. And by then, the costs are already running.

The question "how much would a tribunal cost me?" comes up in almost every conversation I have with founders who've been handling HR themselves. The answer is rarely what they expect. Not because the compensation is always enormous, although it can be. But because the compensation is only part of the cost.

The direct financial cost

Let's start with what you'd owe if you lose. Unfair dismissal compensation has two parts. The basic award is calculated like a redundancy payment: age, length of service, and weekly pay (capped). The compensatory award covers the employee's financial losses, things like lost earnings, loss of statutory rights, and future losses. The cap on the compensatory award is currently the lower of 52 weeks' pay or the statutory cap, which stands at just over £115,000.

But unfair dismissal is often the least expensive claim. Discrimination claims, whether race, sex, disability, age, or any other protected characteristic, have no cap on compensation. The average award for disability discrimination in recent years has sat well above £20,000, and significant claims regularly reach six figures. A successful pregnancy discrimination claim or a disability discrimination claim involving a dismissal can be life-changing for a small business.

Whistleblowing claims are also uncapped. And if a tribunal finds that you unreasonably failed to follow the ACAS Code of Practice, compensation can be increased by up to 25%.

The legal fees

Win or lose, you pay your own legal costs. Employment tribunals don't generally award costs against the losing party unless their case was misconceived or their conduct was unreasonable. So even if you win, you're still paying your solicitor.

For a straightforward unfair dismissal claim that settles before hearing, you're looking at legal fees somewhere in the region of £5,000 to £15,000. A claim that goes to a full hearing over several days will cost significantly more, often £20,000 to £50,000 or higher depending on complexity. Discrimination claims tend to be longer and more document-heavy, so the fees climb.

The hidden costs

These are the ones nobody budgets for. Management time is the biggest. Preparing for a tribunal claim takes dozens of hours. Gathering documents. Writing witness statements. Attending preparation meetings with your solicitor. Giving evidence. For a founder or MD, that's time not spent running the business. I've seen founders lose weeks of productive time to a claim that could have been avoided with a half-hour conversation six months earlier.

Then there's the team impact. Other employees know when a colleague has taken the business to tribunal. It affects morale, it affects trust, and it affects whether your best people stay. A business that's known for handling people badly, even if the claim was ultimately dismissed, carries that reputation in a local market.

For Sheffield businesses specifically, where word travels in sector networks and the business community is closely connected, a tribunal claim becomes part of how people talk about your organisation. That's not fair, but it's real.

The cost of settling

Most claims don't reach a full hearing. They settle. But settlement isn't free either. Settlement agreements typically involve a payment to the employee, their legal fees (usually between £500 and £1,000), and your own legal costs for drafting and negotiating the agreement. A settlement payment can range from a few thousand pounds to significant five-figure sums depending on the strength of the claim and the risk of going to hearing.

Settlement is often the right commercial decision. But it still costs money. And it feels frustrating when the claim arose from a process failure that was preventable.

The prevention calculation

This is the bit that matters. Almost every tribunal claim I've seen in a small business started with a process failure. A dismissal without proper procedure. A grievance that was ignored. A performance problem that was never documented. A reasonable adjustment that was never considered.

The cost of preventing those failures, whether through retained HR support, a one-off process review, or bringing in someone to manage a specific situation properly, is a fraction of the cost of getting it wrong.

I'm not saying every situation needs external help. But if you're about to dismiss someone, restructure a team, or handle a grievance, and you're not confident the process is right, the investment in getting advice is one of the best commercial decisions you'll make.
