The UK Equality Act defines equal value by the demands of a job — effort, skill and decision-making — and makes an analytical job evaluation study decisive in equal-pay claims. A non-analytical, whole-job scheme has no legal effect, so factor-based evaluation is effectively required to defend pay decisions.
The UK's Equality Act 2010 (consolidating the Equal Pay Act 1970) implies a sex equality clause into every employment contract, entitling employees to equal pay with a comparator of the opposite sex doing like work, work rated as equivalent, or — the expansive limb — work of equal value. Section 65(6) defines equal value "in terms of the demands made" on the worker, "by reference to factors such as effort, skill and decision-making."
What makes the UK genuinely distinctive is section 131: where a job evaluation study has rated the claimant's and comparator's jobs differently, the tribunal must reject the equal-value claim — unless the study itself discriminates on grounds of sex. Parliament effectively designated analytical job evaluation as the authoritative answer to the equal-value question. The catch, settled by Bromley v H & J Quick, is that only an analytical study qualifies: jobs must be assessed factor by factor under headings like effort, skill, and decision-making. Whole-job comparisons and "felt fair" rankings have no legal effect — a point the EHRC's statutory Code of Practice makes in terms. And under Hayward v Cammell Laird, equality applies term by term: each contract term (basic pay, bonus, allowances) must be equalized individually, not offset against a generous package overall.
Every employer is exposed — the equality clause operates in all employment contracts, claims can reach back six years in arrears (five in Scotland), and no minimum headcount applies. Separately, employers with 250+ employees must publish annual gender pay gap statistics under the 2017 reporting regulations; that regime is transparency-only and carries no job evaluation requirement, but published gaps routinely seed the questions that become claims.
Equal-value litigation in the UK has moved decisively into the private sector at mass scale. Following the supermarket cases, tens of thousands of predominantly female retail store workers have brought equal-value claims comparing their work to predominantly male distribution-centre roles — multi-year proceedings in which tribunal-appointed independent experts assess the jobs factor by factor, and exposure runs to the hundreds of millions. The litigation wave is the clearest demonstration of section 65(6)'s reach: jobs that look nothing alike on the org chart can be equal in the only terms the law counts.
The UK is outside the EU Pay Transparency Directive, so the June 2026 transposition wave does not apply — but UK-headquartered groups with EU workforces face the Directive there, and its four-factor logic is materially identical to the Equality Act's demands-based test.
Nowhere does job evaluation carry more legal weight than in the UK — section 131 makes a valid study the closest thing to a complete defense that equal pay law offers anywhere:
UK law doesn't make employers evaluate jobs. It does something more pointed: it makes the employers who have — analytically and fairly — nearly unchallengeable, and leaves everyone else to litigate the value of their jobs in front of a tribunal expert.
Not proactively — but UK law gives analytical job evaluation a unique, near-decisive legal status. Under section 131 of the Equality Act 2010, a tribunal must strike out an equal-value claim where a valid job evaluation study has rated the jobs differently — provided the study is analytical and free of sex bias. No other defense in equal pay law carries that weight.
An analytical one — the study must evaluate jobs by reference to the demands made on the worker under factor headings such as effort, skill, and decision-making. Case law (Bromley v H & J Quick) and the EHRC statutory Code are explicit that non-analytical "whole job" or felt-fair rankings have no legal effect as a defense.
Work that is equal in terms of the demands made on the worker, by reference to factors such as effort, skill, and decision-making (section 65(6)). It allows comparison across entirely different jobs — the basis of the mass claims brought by retail store staff comparing themselves to distribution workers.
They're separate regimes. The 2017 reporting regulations require employers with 250+ employees to publish pay gap statistics, but reporting is transparency only — it neither requires nor validates job evaluation. The equal-value risk lives in the Equality Act's equal pay provisions, where an analytical study is the decisive instrument.
