Why Every SME Owner Needs to Understand Tribunal Costs
Most SME owners never expect to face an employment tribunal. It feels like something that happens to larger companies with bigger teams and deeper pockets. But the reality is very different. In 2024/25, over 42,000 single claims were filed with the employment tribunal, a 23% increase year-on-year. With major changes on the way under the Employment Rights Act 2025, that number is only going to grow.
Understanding the true costs of an employment tribunal is the first step to protecting your business. The financial impact goes far beyond the final award, and even winning a case can leave a serious dent in your bottom line.
Legal Fees: What You Can Expect to Pay
Employment law solicitors typically charge between £200 and £400 per hour, and even a straightforward case can run up significant costs quickly. Based on current market rates, here is what employers typically face:
- Simple or straightforward case (1-2 day hearing): £10,000 to £18,000
- Medium complexity case (3-5 day hearing): £18,000 to £30,000
- High complexity case (discrimination, whistleblowing): £24,000 to £54,000 or more
All of those figures are plus VAT at 20%.
Here is the part that catches most business owners off guard: even if you win, you will normally have to absorb your own legal costs. Employment tribunals operate a "each side pays their own" regime. Unlike the civil courts, there is no general rule that the losing party pays the winner's costs. You can defend a claim successfully and still be tens of thousands of pounds out of pocket.
The Management Time You Cannot Get Back
The financial cost of legal representation is only part of the picture. Defending a tribunal claim can consume up to one month of management time when you account for document collation, evidence gathering, preparing witness statements, corresponding with solicitors, and attending the hearing itself.
For an SME with a small leadership team, losing a director or senior manager for weeks at a time has a disproportionate impact on the business. Projects stall, decisions get delayed, and the day-to-day running of the company suffers. That is time you will never recover.
How Long Does It Take?
The average wait from an employment tribunal claim being filed to a final hearing is approximately 12 months, with some claims taking up to 18 months to reach a conclusion. At March 2025, the open caseload stood at 491,000 cases, an 11% increase on the previous year.
For the entire duration of the process, your business operates under a cloud of uncertainty. You cannot close the chapter, and the stress and distraction affect everyone involved.
What Tribunals Actually Award
Based on the latest published data for 2023/24, the average and median awards for unfair dismissal were:
- Average unfair dismissal award: £13,749 (up 15% from the previous year). Unfair dismissal remains the most common claim type, and getting the process wrong is the single biggest trigger.
- Median unfair dismissal award: £6,746
- Maximum basic award (from April 2025): £21,570
- Compensatory award cap (from April 2025): £118,223 or 52 weeks' pay, whichever is lower
Discrimination claims carry significantly higher awards, and crucially, there is no cap:
- Sex discrimination average: £53,403
- Disability discrimination average: £44,483
- Race discrimination average: £29,532
- Highest award in 2023/24: £995,128 (sex discrimination)
These figures demonstrate why discrimination claims in particular represent such a serious financial risk. For a real-world example, see the £1.1 million discrimination payout case study where employer mishandling of mental health needs resulted in a landmark award.
The Hidden Costs That Do Not Appear on an Invoice
Often, the hidden costs of a tribunal claim cause more lasting damage than the legal fees or the award itself.
Staff morale and team dynamics. Colleagues may be called as witnesses, asked to give statements, or drawn into the process in ways that create division within your team. Even staff who are not directly involved will be aware of the situation, and it can erode trust and engagement.
Reputational damage. Tribunal judgments are published online and are publicly searchable. A quick Google search of your company name could surface details of the claim for years to come, affecting how potential clients, partners, and future employees perceive your business.
Social media exposure. Former employees may share their experience on platforms like Glassdoor, LinkedIn, or other social media. You have very limited control over this narrative once a claim is public.
Recruitment costs. If existing staff leave during the disruption, replacing them typically costs between £3,000 and £12,000 per hire, depending on the role and seniority.
Productivity loss. With key people diverted from running the business, revenue-generating activity slows. For an SME, this can be the most damaging cost of all.
Why the Risk Is Increasing
The Employment Rights Act 2025 introduces several changes that will significantly increase the risk of tribunal claims for SMEs:
- From January 2027, the qualifying period for unfair dismissal claims drops from 2 years to just 6 months. This means far more employees will have the right to bring a claim, far sooner.
- The compensatory award cap is being removed entirely, introducing unlimited liability for unfair dismissal awards.
- Tribunal time limits are extending from 3 to 6 months (from October 2026), giving employees a much longer window in which to bring a claim.
- ACAS early conciliation has been extended to 12 weeks (from December 2025), changing the pre-claim landscape.
Taken together, these changes mean more claims, from more employees, with higher potential awards.
Settlement vs Tribunal: The Numbers Speak for Themselves
The good news is that the vast majority of disputes never reach a full hearing. Nine out of ten ACAS early conciliation cases resolve without a tribunal claim being filed, and 79% of tribunal cases that are filed settle before reaching a hearing.
Settling early typically costs between £2,000 and £5,000 in legal fees, compared to £10,000 to £54,000 for a full hearing. A settlement agreement is often the most practical route, giving both sides certainty and a clean break. When you factor in the management time, stress, and hidden costs, early resolution almost always represents better value.
But the most cost-effective approach of all is getting it right from the start.
How to Reduce Your Risk
Prevention will always cost less than a cure. Here are five practical steps every SME should take:
- Follow the Acas Code of Practice for disciplinary and grievance procedures. Tribunals can increase awards by up to 25% if you fail to follow the Code. This is especially important when handling gross misconduct, where employers often rush to dismiss without proper investigation.
- Document everything. Keep written records of policies, meetings, performance discussions, and decisions. If it is not documented, it did not happen.
- Take professional HR advice before making difficult decisions. Whether you are considering a dismissal, a restructure, or responding to a grievance, getting expert guidance at the right moment can prevent a costly mistake.
- Keep contracts and policies up to date. Employment law changes regularly, and outdated documentation leaves you exposed.
- Train your managers. Many tribunal claims stem from managers handling situations poorly. Investing in HR training gives your team the skills to manage people fairly and consistently.
Get It Right From the Start

Frequently Asked Questions
- How much does it cost to defend an employment tribunal claim?
- Legal fees for defending a tribunal claim typically range from £10,000 to £18,000 plus VAT for a simple case, £18,000 to £30,000 for medium complexity, and £24,000 to £54,000 or more for discrimination or whistleblowing claims. Employment tribunals operate an each-side-pays regime, so even a successful defence leaves you absorbing your own costs. Settlement often represents better value than a full hearing.
- What is the average unfair dismissal award in the UK?
- For 2023/24 the average unfair dismissal award was £13,749, up 15% year-on-year, with a median of £6,746. The maximum basic award from April 2025 is £21,570, and the compensatory award is capped at the lower of 52 weeks pay or £118,223. Discrimination awards are uncapped and significantly higher. The 2023/24 highest sex discrimination award reached £995,128.

Your business operates under a cloud of uncertainty throughout, losing management time, productivity, and often staff morale during the extended process.
- What is the 25% Acas Code uplift?
- Under section 207A of TULRCA 1992, if an employer unreasonably fails to follow the Acas Code of Practice on Disciplinary and Grievance Procedures, a tribunal can increase any compensation award by up to 25%. If the employee fails to follow it, the award can be reduced by up to 25%. This makes Code compliance one of the cheapest and most effective ways to limit financial exposure.
- Why are tribunal risks rising for SMEs in 2026 and 2027?
- Four Employment Rights Act 2025 changes are increasing risk: tribunal time limits extend from three to six months in October 2026, the unfair dismissal qualifying period drops from two years to six months in January 2027, the compensation cap is being removed entirely, and Acas early conciliation has already extended to 12 weeks from December 2025. More claims, longer windows, and unlimited liability.

- Five practical steps significantly reduce risk: follow the Acas Code of Practice, document every policy, meeting, and decision, take professional HR advice before making difficult decisions like dismissals or restructures, keep contracts and policies current with employment law changes, and train your managers. Prevention almost always costs a fraction of defending a claim, even when you win at tribunal.
