Ethnicity and Disability Pay Gap Reporting: What Large UK Employers Need to Know

Gender pay gap reporting has been a mandatory obligation for large UK employers since 2017, requiring organisations with 250 or more employees to publish their mean and median gender pay gaps annually. The government has now confirmed it will extend a broadly similar reporting model to two further categories — ethnicity and disability — through the anticipated Equality (Race and Disability) Bill. For HR and payroll teams already familiar with gender pay gap reporting, the mechanics will feel recognisable, but ethnicity and disability data bring genuinely distinct challenges that gender pay gap reporting never had to solve.

This guide sets out who will be covered, what will need to be reported, and the specific complications employers should start planning for now.

Who will be covered

The mandatory requirement is expected to apply to employers with 250 or more employees in Great Britain — the same threshold used for gender pay gap reporting. Smaller employers will be able to report voluntarily, but will not be required to. Any organisation already caught by gender pay gap reporting should assume it will also be caught by the new ethnicity and disability requirements once they come into force.

What will need to be reported

The core metrics mirror the existing gender pay gap framework closely: mean and median hourly pay differences, mean and median bonus pay differences, the proportion of employees receiving a bonus, and the distribution of employees across pay quartiles — all broken down by ethnicity and by disability status rather than by gender. Employers will also need to report their workforce composition by ethnicity and disability, and, distinctively, their "declaration rates" — the proportion of employees who choose not to disclose their ethnicity or disability status at all. This last metric has no real equivalent in gender pay gap reporting, where an employee's gender is very rarely undisclosed to their employer, and it exists precisely because non-declaration is expected to be a much more significant issue for these two new categories.

Why ethnicity and disability data is genuinely harder to work with

Gender pay gap reporting works with a relatively small number of categories and high employee disclosure rates. Ethnicity and disability reporting faces two structural complications gender pay gap reporting did not:

• Granularity versus anonymity. The proposed approach requires employers to collect ethnicity data using the detailed 19-category government classification system, but to report using five broader ONS groupings — White, Asian, Black, Mixed, and Other — once minimum thresholds are met, in order to protect the anonymity of employees in smaller demographic groups within a workforce. Employers will need systems capable of collecting granular data while reporting only the aggregated version.
• Disclosure reluctance. The proposed disability approach uses a binary disabled/non-disabled distinction based on the Equality Act 2010 definition, again with minimum thresholds to protect privacy, but disability status carries disclosure sensitivities that ethnicity data generally does not — employees can be reluctant to disclose a disability to their employer at all, for reasons ranging from stigma to concern about career impact. This makes the declaration rate metric especially significant for disability reporting: a low declaration rate can undermine the reliability of the reported pay gap figures themselves, and may itself become something employers are implicitly judged on.

Timeline — this is further out than it might sound

Employers should not mistake "confirmed" for "imminent." The regime is expected to be operational by 2029 through the Equality (Race and Disability) Bill, with associated action plans — intended to sit alongside the existing mandatory gender pay gap action planning requirement and a planned menopause action plan requirement — expected from spring 2027. This is a considerably longer runway than some of the UK's other 2026 employment reforms, and reflects the genuine complexity of building reliable, anonymity-protecting data collection systems for two new demographic categories at once.

That longer timeline is a reason to start early, not a reason to deprioritise the issue. Building the data collection infrastructure, and — just as importantly — building employee trust in why the data is being collected, so that declaration rates end up meaningfully higher than a reluctant baseline, takes years rather than months to get right.

How this connects to existing pay transparency obligations

Employers already managing gender pay gap reporting and action planning have a natural starting point: the underlying payroll and HR data infrastructure built for that requirement is a foundation the ethnicity and disability regime can extend, rather than something built from scratch. The same broader direction of travel — greater mandatory transparency around pay and how it's determined — is visible elsewhere in 2026's compliance landscape, including in EU and Irish pay transparency requirements for job adverts, even though that reform operates under different legislation and in a different jurisdiction.

Frequently asked questions

Which employers will be required to report ethnicity and disability pay gaps?

Employers with 250 or more employees in Great Britain are expected to be covered, matching the existing gender pay gap reporting threshold. Smaller employers will be able to report voluntarily.

When will mandatory ethnicity and disability pay gap reporting take effect?

The regime is expected to be operational by 2029 through the anticipated Equality (Race and Disability) Bill, with associated action plans expected from spring 2027.

Why does the reporting framework include a "declaration rate" metric?

Because employees are expected to be more reluctant to disclose ethnicity — and particularly disability — status than gender, a low declaration rate can undermine the reliability of the reported pay gap figures. Reporting the declaration rate itself gives readers of the data a sense of how complete and reliable the underlying figures are.

Ethnicity and disability pay gap reporting extends a familiar reporting model into genuinely harder data territory, and the multi-year timeline to 2029 is there for a reason — employers with a 2027 or 2029 compliance deadline on the horizon should treat the data collection and employee trust-building work as starting now, not as something to pick up closer to the deadline.
