Employment Tribunal Statistics 2026: Claims Hit a Record High, and the Real Surge Hasn't Started Yet

The Ministry of Justice has just published its latest quarterly tribunal statistics and the numbers make sober reading for any business. Single employment tribunal claims are up 28% on the same period last year, with 14,000 new single claims received between April and June. Disposals moved in the opposite direction, falling 6% over the same period. The result is an open single caseload of 70,000, up 51% in a year, and the highest level recorded since the data series began. Across single and multiple claims combined, 537,000 cases were open at the end of June.

What makes this genuinely alarming is that every one of those claims was brought under today's rules: a two-year qualifying period for ordinary unfair dismissal and a three-month window, less a day, to bring most claims. The system is already under significant strain before any of the reforms due this year and next have taken effect.

Why the System Is About to Come Under More Pressure

From 1 October 2026, the limitation period for most tribunal claims, including unfair dismissal, discrimination, detriment, working time, and TUPE, doubles from three months to six. Claims that previously died quietly, because an employee was signed off sick, waiting on an internal appeal, or simply unaware of the time limit, will increasingly survive to be brought.

It's also worth remembering that six months isn't really six months. Add the mandatory period for Acas early conciliation and an ET1 may not land on an employer's desk until close to a year after the dismissal took place. Document retention policies built around a three-month time limit, as most still are, may now be destroying evidence that could be needed to defend a claim brought many months later.

Then, on 1 January 2027, the unfair dismissal qualifying period reduces from two years to six months. Government estimates suggest around 6.3 million employees currently sit within the six-month to two-year service band, potentially bringing a substantial number of them into scope to claim for the first time, alongside removal of the compensation cap.

A Cultural Shift, Not Just a Legal One

The statistics alone don't capture everything driving this trend. Employees now have free access to tools that can draft a grievance, value a potential claim, and complete an ET1 form in minutes. As the cost of escalating a workplace dispute falls toward zero, it's a reasonable expectation that more people will choose to do so. Combined with growing general awareness of employment rights, this points toward a tribunal system that will remain under sustained pressure for the foreseeable future, regardless of any single legislative change.

Impact

The temptation for many businesses will be to note these figures, feel a flicker of concern, and put a proper review of contracts, policies and processes off until later in the year. That's an understandable response, but a risky one. A probation period that drifts a week too long, a dismissal without a clear paper trail, or a document retention policy still built around a three-month time limit can each turn what should have been a manageable situation into a live tribunal claim, defended months after the event with limited evidence to hand.

We help employers review probation periods and dismissal processes so they hold up under the tighter timelines coming this year and next, advise on document retention policies that now need to reflect six month limitation periods rather than three, and provide hands on support if a claim is brought, from early risk assessment through to ET3 drafting and representation at hearing.

With claim volumes already at record levels and further reform still to land, the businesses in the strongest position will be the ones that review their processes now, rather than waiting for a claim to arrive.

It is also worth reviewing your business insurance cover and obtain a quote for Tribunal claim cover. This often includes covering the legal costs in defending any claim plus any awards and potentially any settlements.
