Why UKI SMEs Are Facing Record Employment Tribunals in 2026

Open employment tribunal claims in the UK rose by 12% in Q3 2025/26, reaching a record backlog of approximately 523,000 open claims. Across the pond in Ireland, the Workplace Relations Commission received 10,559 complaint applications in 2025 — a 44% increase compared to the previous year. For the CEOs and HR leads running lean British and Irish teams, the maths is simple: claims are outpacing resolutions two-to-one, the backlog is past half a million, and your sector is not exempt.

The surge is not accidental. It is the predictable consequence of a landmark piece of legislation landing in a market where many SMEs haven't yet caught up. The Employment Rights Act 2025, described as the most significant overhaul of UK employment law in a generation, activated its first major wave of changes on 6 April 2026, introducing sweeping day-one rights and stricter compliance measures that immediately impact how small and medium-sized enterprises operate. Day-one statutory sick pay. Day-one paternity leave. And from October 2026, the time limit for bringing most tribunal claims doubles from three to six months — meaning employees have longer to decide whether to act.

Consider what that timeline means in practice. A company of 40 people onboards a new hire in July, handles a performance issue poorly in October, and by January finds themselves responding to a claim that — under the old rules — would have been out of time. Any staff hired from July 2026 onwards will be subject to a tighter unfair dismissal timeline, once the qualifying period drops from two years to six months in January 2027. The window is closing faster than most HR teams realise.

The enforcement picture has also shifted. The Fair Work Agency, launched on 7 April 2026 as part of the Employment Rights Act, has powers to inspect workplaces, investigate possible breaches, and issue penalties. This is no longer a time where non-compliance surfaces only when an individual employee raises a grievance; the state can now come looking. In Ireland the WRC Inspectorate is already demonstrating what proactive enforcement looks like — 223 prosecutions were brought in 2025, up from 175 the previous year, with an 82% success rate.

What makes all of this particularly damaging for smaller businesses is that the costs extend well beyond any final fine. For employers, record claim volumes mean longer timelines, increased costs, and prolonged uncertainty. Legal fees, management time, HR distraction, damage to team morale — none of that shows up in a compensation figure.

The volume and speed of incoming legislation would test any dedicated HR team; for SMEs managing compliance alongside everything else, the risk of gaps is real. The Employment Rights Act 2025 alone is expected to increase claims further, with an additional six million workers potentially gaining the right to bring unfair dismissal claims once qualifying period changes take effect. That is a significant expansion of the pool of people who can formally challenge your decisions. 

The good news is that the exposure is largely preventable. Good people management, robust processes, and a single source of truth for your people data proactively resolves issues before they escalate into tribunal proceedings. The companies getting ahead of this aren't waiting for a claim to land before they tighten up their documentation, train their managers, or audit their contracts. They're doing it now, in their process, systems and teams.
