Employment tribunals are more common — and more costly — than most UK business owners realise. In the second quarter of 2025 alone, single Employment Tribunal claims rose by 33% compared to the previous year. The backlog of open cases now stands at over half a million, and with the Employment Rights Act 2025 bringing sweeping new protections for employees from April 2026, the risk for employers has never been greater.
The good news? Most tribunal claims are preventable. With the right HR processes in place, you can significantly reduce your exposure. Here is what UK employers need to know right now.
Why Tribunal Claims Are Rising
Since tribunal fees were abolished in 2017, it costs employees nothing to bring a claim. That single change transformed the landscape. Claims have risen steadily ever since, and the pace is accelerating. Unfair dismissal accounts for nearly 24% of all new claims, followed by disability discrimination and unauthorised deductions of wages.
What makes 2026 particularly significant is the introduction of major new rights under the Employment Rights Act 2025. From April 2026, Statutory Sick Pay becomes payable from day one, paternity leave becomes a day one right, and the collective redundancy protective award doubles from 90 to 180 days’ pay. From January 2027, the qualifying period for unfair dismissal is expected to fall from two years to just six months. Employers who do not update their policies and contracts face real legal exposure.
The Real Cost of Getting It Wrong
Many employers focus only on compensation awards when assessing tribunal risk. In reality, the full cost is much higher. In an unfair dismissal claim, a compensatory award can reach up to £118,223 or 52 weeks’ gross pay — whichever is lower. In whistleblowing or health and safety cases, there is no cap at all.
Beyond compensation, employers also face legal fees, management time (research shows businesses spend an average of 4.8 weeks managing each tribunal claim), operational disruption, reputational damage, and the knock-on impact on staff morale. For small businesses, a single tribunal claim can be genuinely destabilising.
The Five Most Common Causes of Employment Tribunals
Most claims stem from a handful of avoidable situations:
- Unfair or poorly documented dismissals — where the employer cannot demonstrate a fair reason and a fair process
- Discrimination — covering age, sex, race, disability, religion and other protected characteristics
- Breach of contract — including issues with pay, hours, or terms not reflected in updated contracts
- Failure to follow a fair disciplinary or grievance process — even valid decisions can be overturned if the process was flawed
- Poor management of sickness absence — particularly long-term absence, where legal obligations are complex
How to Protect Your Business: Practical Steps
You do not need to be a large business with an in-house legal team to protect yourself effectively. These are the areas to prioritise:
1. Keep Employment Contracts Current
Many businesses are still using employment contracts that predate significant legal changes. With the Employment Rights Act 2025 introducing new rights from April 2026, now is the time to review and update every contract. Pay particular attention to zero-hours arrangements, flexible working clauses, and sick pay provisions.
2. Follow a Fair Process — Every Time
Employment tribunals assess both the reason for a decision and the process used to reach it. A decision can be entirely justified on the facts yet still result in a tribunal ruling against the employer if the process was unfair. Always follow the ACAS Code of Practice on disciplinary and grievance procedures, document every stage, and give employees the opportunity to respond.
3. Train Your Managers
Most tribunal claims begin at team or line manager level — in a poorly handled performance conversation, an inconsistently applied absence policy, or a dismissal decision taken without HR advice. Regular manager training on disciplinary procedures, absence management, and how to handle sensitive conversations is one of the most effective risk-reduction investments any employer can make.
4. Document Everything
If a claim reaches a tribunal, your documentation becomes your evidence. Keep clear written records of all HR conversations, warnings, investigations, and decisions — along with the reasoning behind them. A well-documented HR paper trail can be the difference between winning and losing a claim.
5. Act Early When Issues Arise
Early resolution is almost always less damaging than allowing a dispute to escalate. If an employee raises a grievance, take it seriously and deal with it promptly. The ACAS Early Conciliation period has recently doubled to 12 weeks (from December 2025), giving employers more time to reach a resolution before a formal claim is lodged.
When to Bring in External HR Support
For most SMEs, the safest and most cost-effective approach is to work with an outsourced HR consultancy before issues arise — not only after they do. A CIPD-qualified HR professional can review your contracts and policies, advise on specific situations before they escalate, and represent your interests if a claim is made.
The cost of proactive HR support is a fraction of the cost of defending a tribunal claim. For businesses operating in higher-risk sectors such as healthcare, construction, or education, or those with a growing headcount, having experienced HR support on hand is not optional — it is a genuine business necessity.
