The landscape of pay gap reporting is expanding dramatically. Whilst organisations have grown comfortable with gender pay gap requirements, a seismic shift is coming that will demand far more sophisticated data collection, analysis, and storytelling capabilities.
The expanding mandate
UK developments
The proposed Equality Bill will extend mandatory pay gap reporting beyond gender to include ethnicity and disability gaps for organisations with 250 or more employees. This isn’t simply adding two more calculations to your annual reporting – it represents a fundamental shift in how you’ll need to collect, understand, and analyse workforce data.
EU pay transparency directive
For organisations operating across Europe, the EU Pay Transparency Directive requires implementation by 2026. This affects:
- Organisations with 250+ employees: Annual reporting from 2026
- Companies with 150-249 EU employees: Reporting every three years from 2026
- Organisations with 100-149 EU employees: Reporting every three years from 2030
However, individual countries are setting stricter thresholds. Belgium, France, Italy, and Ireland require reporting for organisations with 50+ employees. Denmark’s threshold is just five employees, whilst Sweden has no minimum threshold at all.
The data challenge
Beyond binary reporting
Ethnicity pay gap reporting introduces complexity that doesn’t exist with gender reporting. Rather than two categories, you’ll need to navigate multiple ethnic identities, likely mapped to census categories, whilst using inclusive language that doesn’t alienate your workforce.
Disability reporting, whilst appearing simpler with its binary yes/no approach based on Equality Act definitions, brings its own challenges around disclosure rates and the sensitive nature of the data.
The three data types you need to understand
Broad category data: High-level demographic information grouped into larger categories (such as “global majority” versus “white” employees). This provides larger sample sizes for analysis but loses nuance and can homogenise diverse groups.
Specific category data: More detailed breakdowns (such as different ethnic backgrounds or types of disability) that maintain anonymity whilst providing richer insights. This enables targeted interventions but may result in some groups being too small to report on.
Complex/qualitative data: Highly detailed, intersectional information that’s invaluable for understanding individual experiences but difficult to analyse at scale or generalise from. This provides context for your quantitative findings.
The legal landscape is changing whether organisations are ready or not.
We recently hosted a webinar exploring legislative changes affecting employment and inclusion in 2025 and beyond. Covering pay gap reporting, harassment liability responsibilities and the Supreme Court judgement, this was a highly valuable session packed full of insights and practical takeaways.

Key success factors
1. Build data literacy first
Before collecting any additional data, invest in building organisational understanding about why you’re collecting it, how it will be stored, and what protections are in place. People need to understand the personal benefit before they’ll trust you with sensitive information. This is vital regardless of if you choose to mandate disclosure or not. Mandating data disclosure whilst legal should be a last resort, as persistent low disclosure rates are often a sign of low psychological safety which will not be helped by a mandate.
2. Ensure legal compliance
Data collection requirements vary significantly across jurisdictions. What’s acceptable in one country may breach privacy laws in another. This is particularly crucial for global organisations. In a UK setting we would encourage you to be collecting age, ethnicity, disability, gender identity, gender reassignment, religion/belief, and sexual orientation as a minimum. Then exploring any other characteristics that may be relevant to your workforce or industry, for example, caring responsibilities, social mobility or military service.
3. Use inclusive language
Simple choices matter enormously. Listing ethnicity options alphabetically is best practice. Placing “white” at the top of your ethnicity options sends a powerful often unintentional message about assumed hierarchy. Always include “prefer not to say” options and remember that this is still valuable data that you can use to inform organisational decision making.
4. Integrate with HR systems
Anonymous surveys provide snapshots, but integrating diversity data into your HR systems enables you to track progression, retention, and other key metrics across different demographic groups. This reveals patterns that representation data alone cannot show.
5. Look beyond representation
Representation is just one metric and isn’t easily comparable across organisations due to industry, location, and size differences. Analyse the entire employee journey from recruitment to retirement, examining each stage by demographic characteristics to identify where inequities occur.
6. Combine numbers with stories
Use quantitative data to identify patterns, then employ qualitative research (e.g. focus groups, interviews, employee networks) to understand the context behind those patterns. Use open-text survey questions sparingly; they’re time-consuming to analyse properly and should provide context, not replace targeted questioning.
The storytelling revolution
Future pay gap reporting won’t just require publishing numbers. You’ll need to provide compelling narratives explaining your data and concrete action plans for addressing any gaps discovered. This shift towards accountability means organisations must demonstrate not just awareness of pay gaps, but active commitment to reducing them.
Real-world success: Places for People
When Places for People, a large UK property development organisation with 20 different businesses, faced fragmented data across their portfolio, they implemented a comprehensive solution:
- Streamlined multiple HR systems into one coherent platform
- Built data literacy across all acquired organisations
- Launched a comprehensive data campaign involving emails, newsletters, videos, and manager cascades
- Focused on connecting data collection to individual workplace improvements
The results were impressive: disclosure rates increased by 13 percentage points (from 38% to 51%) immediately after the campaign and continued rising. This positioned the organisation to make evidence-based decisions and demonstrate meaningful change over time.
Getting started: your action plan
Phase 1: foundation building
- Audit current data collection practices
- Assess disclosure rates and data quality
- Build data literacy among leadership and colleagues
- Establish clear data governance frameworks
Phase 2: system integration
- Integrate diversity data collection into HR systems
- Develop reporting capabilities
- Create templates and processes for regular analysis
- Train managers on data-informed decision making
Phase 3: advanced analytics
- Implement intersectional analysis where sample sizes allow
- Develop predictive modelling for retention and progression
- Create dashboards for ongoing monitoring
- Establish feedback loops with various stakeholder groups
Why expert support makes the difference
The complexity of modern diversity data requirements means attempting this alone is both risky and inefficient. Organisations need specialist expertise to navigate legal requirements, build effective collection strategies, and create meaningful analysis frameworks.
Inclusive employers’ diversity data consultancy provides comprehensive support including:
- Data strategy development: Tailored approaches that comply with local laws whilst maximising insight value
- System integration support: Technical expertise to embed diversity data into existing HR platforms
- Campaign design: Proven methodologies for increasing disclosure rates and building data trust
- Analysis and reporting: Expert interpretation of complex data patterns and professional report writing
- Training and capability building: Upskilling your team to maintain and develop data practices independently
- Ongoing support: Regular reviews and updates as legal requirements and best practices evolve
Don’t risk potential fines by waiting until reporting becomes mandatory to begin building your data capabilities. Effective diversity data strategies take years to mature, and organisations starting now will have significant advantages over those who delay.
