UK Pay Transparency 2026: What's Actually Mandatory for Employers (and What Isn't)

Partially, and less than most people assume. UK employers with 250 or more staff have had to publish annual gender pay gap figures since 2017, and that has not changed. What is new is the direction of travel: the Employment Rights Act 2025 (Royal Assent 18 December 2025) introduces gender pay gap action plans, which move from voluntary in April 2026 to compulsory for large employers from spring 2027. But there is still no UK law requiring salary ranges in job adverts, unlike Ireland, which must transpose the EU Pay Transparency Directive by June 2026.

No. As of 2026, there is no legal requirement in the UK to publish a salary range in a job advert or to disclose one before interview, unlike Ireland's incoming EU-directive obligation. Some employers do it voluntarily, often because major job platforms increasingly nudge or default toward salary ranges being shown, and because candidates in competitive tech hiring markets have come to expect it. But it remains a market practice, not a legal one, in the UK.

Reporting is the annual publication of your gender pay gap figures (mean and median pay gap, bonus gap, and pay quartile distribution), which has been mandatory for 250+ employee employers since 2017. An action plan goes further: it requires the employer to set out concrete steps to close the gap it has reported, not just disclose the number. Action plans move from voluntary (April 2026) to compulsory for large employers from spring 2027 under the Employment Rights Act 2025, with the first compulsory plan due by 4 April 2028.

Not yet. On 25 March 2026, the government confirmed its commitment to introducing mandatory ethnicity and disability pay gap reporting for employers with 250 or more staff, following a consultation in which 87% of respondents supported the move. That is a policy commitment, not enacted legislation: no implementation timeline has been set as of mid-2026. Employers should treat it as a when, not an if, and start collecting the underlying data now rather than waiting for the law to land.

Ireland is ahead of the UK on the specific point that tends to matter most to candidates: salary ranges in job adverts. Ireland must transpose the EU Pay Transparency Directive into law by June 2026, which mandates salary range disclosure in job postings, a ban on asking candidates about salary history, and employee rights to pay comparison data. The UK, outside the EU, has none of these as binding law. Where the UK is ahead is longevity: its gender pay gap reporting regime has been running since 2017, versus Ireland's regime which only began phasing in from 2022.

Equality Action Plans are government guidance, published in March 2026, setting out 18 recommended actions for employers on gender equality, one of which is to increase pay transparency. They are currently a recommended framework, not a legal mandate, and sit alongside (and partly overlap with) the incoming compulsory gender pay gap action plans under the Employment Rights Act 2025. Employers who adopt the guidance early are effectively rehearsing for the compulsory regime that arrives from spring 2027.

Increasingly, yes, for competitive reasons rather than legal ones. Job postings with a published salary range consistently attract higher application volumes and better-fit candidates, and reduce late-stage offer declines caused by a mismatch discovered only at the final stage. In tech hiring specifically, candidates routinely filter out listings with no salary range before applying. Waiting for a legal mandate that does not yet exist in the UK means losing candidates to competitors who disclose voluntarily.

Three steps put you ahead of the curve rather than scrambling once law catches up with practice. First, build defensible, market-calibrated salary bands for every role and level, so you have a credible answer the moment ranges become expected or required. Second, start collecting ethnicity and disability pay data now, since mandatory reporting on both has been committed to even without a date attached. Third, treat the 2026 voluntary phase of gender pay gap action plans as a dry run, since the same employers will face a compulsory version from spring 2027.
