Tesco Supreme Court Equal Pay: 16,000 Store Workers Cleared for Trial After Appeal Refused
If you work or have ever worked in a Tesco store, the legal process that could result in substantial back pay moved one step closer this month. The UK Supreme Court refused Tesco permission to appeal a key ruling on how employment tribunals assess job comparisons between store workers and warehouse staff. The path to a full equal-value hearing is now clear.
The Supreme Court’s refusal targets the Court of Appeal judgment in Tesco Stores Ltd v Element & Ors [2026] EWCA Civ 580, decided in May 2026. Around 16,000 claimants are represented by law firm Leigh Day. Estimated financial exposure across the wider retail sector reaches £4 billion, covering comparable equal pay claims at multiple supermarket groups. The dispute centers on whether employment tribunals can use Tesco’s central training manuals and operational documents to establish job requirements — rather than demanding individual task-by-task diaries from each claimant.
Store-level supermarket workers are closer to substantial back-pay awards, but no payments have been ordered yet. What changed is procedural: employers can no longer stall tribunal proceedings by demanding workers prove their duties minute by minute. If you currently work or previously worked in a retail store role at Tesco, you do not receive automatic compensation. What the ruling does is clear the way for the substantive equal-value trial — the hearing that will directly determine whether hourly rates for store workers should match those of distribution centre staff — to proceed without further procedural delay.
What the Court Actually Decided
The Court of Appeal in [2026] EWCA Civ 580 ruled that “work” is defined by the objective contractual and training framework: what the company contracts and trains workers to do, not what any individual worker happened to do on a given shift. This means Tesco cannot argue that store workers operated differently from its own training manuals while simultaneously claiming that warehouse workers carried superior contractual responsibilities. The Supreme Court’s refusal to hear an appeal confirmed that ruling as settled law.
Employment partner Kiran Daurka at Leigh Day confirmed the decision clears the route to trial. The same legal principle is relevant to equal pay actions against Asda, Sainsbury’s, and Morrisons, all of which face comparable claims. Together the wider supermarket sector faces an estimated £4 billion exposure across all pending actions.
Legal representatives will manage the tribunal process for registered claimants. The question for the forthcoming equal-value hearing is whether the work done on a shop floor is legally equivalent in value to work done in a distribution centre.
Did Tesco lose the equal pay claim?
Not finally. The Supreme Court refused Tesco permission to appeal a procedural ruling on how job duties are assessed at tribunal. The decision confirms that employment tribunals can use Tesco’s official training and operational manuals as job benchmarks. This removes a major procedural hurdle and sends the case to a substantive equal-value trial, which will determine whether and how much compensation store workers are owed.
The case proceeds to an equal-value hearing in the Employment Tribunal. No date has been publicly confirmed. A finding against Tesco at that stage would trigger compensation calculations across thousands of individual claimants.
