Find out how employers in the UK must prevent gender pay discrimination through equal pay compliance, transparent pay structures, gender pay gap reporting for large employers, pay audits, action plans and open communication to reduce inequality and avoid tribunal claims.
Gender pay discrimination remains a significant legal and ethical issue for businesses in England and Wales. Employers have clear legal obligations to ensure that women and men are paid fairly and that differences in pay are not the result of unlawful discrimination based on sex. These obligations arise under the Equality Act 2010, supported by equal pay law, gender pay gap reporting regulations, and related guidance on fair pay practices. This article explains what gender pay discrimination is, the legal framework employers must comply with, practical steps to prevent discrimination, monitoring and reporting duties, and the risks of non‑compliance.
What Is Gender Pay Discrimination?
Gender pay discrimination occurs when men and women performing equal or comparable work receive unequal pay or benefits on the basis of their sex. It encompasses both direct discrimination (paying a woman less than a man for the same work) and indirect discrimination (policies or practices that disproportionately disadvantage women, such as bonus structures that favour long hours incompatible with caregiving patterns). Both can lead to legal claims and tribunal proceedings if not addressed properly. Equal pay rights support fairness and are a cornerstone of employment equality law in the UK.
Legal Framework: Equality Act 2010 and Equal Pay Rights
The Equality Act 2010 prohibits less favourable treatment because of a protected characteristic - including sex - and implies an equal pay clause into every contract of employment. This means:
- Men and women must receive equal pay for equal work, unless a legitimate, non‑discriminatory reason can justify difference.
- “Pay” covers basic salary, bonuses, overtime, allowances, benefits in kind and other terms and conditions of employment.
- Equal pay rights apply to employees and workers under contract with the same employer or associated employers.
Employers cannot justify a pay difference on the grounds of sex unless they can show a material factor unrelated to gender that fully explains the disparity.
Gender Pay Gap Reporting Duties
Large employers face an additional layer of gender pay transparency requirements. Regulations require employers with 250 or more employees to calculate and publish gender pay gap data annually. This involves publishing:
- The mean and median gender pay gap figures for hourly pay and bonuses.
- The proportion of men and women receiving bonuses.
- The distribution of male and female employees across pay quartiles.
- A narrative statement explaining causes and actions where appropriate.
This data must be reported via the government's gender pay gap service and published on the employer's own website. Failure to report accurately and on time can lead to enforcement action by the Equality and Human Rights Commission (EHRC), including fines or legal orders.
Practical Steps to Prevent Gender Pay Discrimination
1. Implement Transparent Pay Structures
Employers should develop clear and transparent pay frameworks that articulate how pay and benefits are determined. This includes job evaluation criteria, scales for progression, and rules for bonuses. Transparency reduces the risk of arbitrary or subjective decisions that could reinforce bias.
2. Conduct Pay Audits Regularly
Regular pay audits help identify disparities between men and women in similar or comparable roles. Audits should include basic pay, bonuses, overtime and benefits. Where disparities are identified, employers should investigate whether legitimate, non‑discriminatory reasons exist and take remedial action if necessary.
3. Analyse Recruitment and Promotion Practices
Discrimination can arise not only in pay but in how employees progress. Employers should examine recruitment, promotion and reward processes for bias and ensure criteria are fair and objective. For example, structured scoring systems for promotions and job evaluations can help mitigate subjective bias.
4. Engage in Gender Pay Gap Reporting and Action Plans
For employers required to report, producing a gender pay gap report involves not only calculating figures but explaining them and committing to measurable action. Although action plans are voluntary currently, proposed changes from 2027 suggest employers will need to formalise these plans with targets and timelines. Understanding the causes of a gap and putting in place actions to narrow it supports both legal compliance and workplace fairness.
5. Support Pay Disclosure and Open Communication
Employers must be aware that contractual restrictions on discussing pay may be unenforceable if they prevent employees comparing pay to identify discrimination. Under section 77 of the Equality Act 2010, “pay secrecy clauses” that prohibit relevant pay disclosures are unenforceable and attempting to enforce them may lead to claims of victimisation or unfair dismissal. Employers should instead foster open, respectful dialogue about pay where appropriate.
Addressing Gender Pay Discrepancies
When audits or reporting reveal gender pay gaps:
- Analyse whether differences stem from structural issues (e.g. more men in senior roles) rather than unlawful pay discrimination.
- Develop evidence‑based action plans that include targets to close gaps, improve flexible working, and ensure equitable access to bonuses and promotions.
- Consult with employees or representatives when crafting and implementing action plans to build trust and shared responsibility.
While not all gaps indicate unlawful discrimination, sustained disparities without legitimate justification can expose employers to legal exposure and reputational harm.
Enforcement and Legal Consequences
Tribunal Claims and Compensation
Where a woman believes she has been paid less than a male comparator for equal work, she can bring an equal pay claim to an employment tribunal. Claimants generally must start proceedings within six months of the act of unlawful pay difference. If successful, tribunals can award back pay, interest, and adjustments to contractual terms. Employers must provide evidence that any disparity was due to material factors unrelated to sex.
EHRC Enforcement of Reporting Duties
Failing to comply with gender pay gap reporting can result in enforcement actions, such as warning notices, enforcement orders and financial penalties. Public visibility of reporting performance also carries reputational risk, particularly when data is made available on public government services.
Common Questions
Is gender pay reporting the same as equal pay law?
No. Equal pay law prohibits paying men and women differently for equal work. Gender pay gap reporting highlights overall differences in average pay between genders across pay structures and is a transparency measure for larger employers. They complement each other but serve distinct functions.
Can an employer ban pay discussions?
Employers cannot enforce pay secrecy provisions that prevent employees from discussing their pay for the purpose of identifying potential discrimination, because such clauses are unenforceable under section 77 of the Equality Act 2010, and sanctions for discussing pay can amount to victimisation.
What if the gender pay gap reporting shows a large gap?
A large gap does not necessarily mean discrimination has occurred, but it signals the employer should investigate causes, explain findings in the narrative, and implement an action plan where appropriate to address structural imbalances and support gender equality.
Key Takeaways
Employers in England and Wales must take proactive steps to prevent gender pay discrimination and demonstrate fairness in pay practices. This includes complying with equal pay obligations under the Equality Act 2010, implementing transparent pay frameworks, conducting pay audits, engaging in gender pay gap reporting for larger employers, and taking action where disparities are identified. Supporting open communication about pay and preparing evidence‑based action plans helps reduce legal risk, improve workplace equality, and ensure compliance with statutory requirements.
