A colleague doing work of equal value earns £5,000 more than you each year. Your job titles differ, but the responsibility, decision-making and demands of the roles appear closely matched. This equal pay claim example shows why the issue is rarely resolved by comparing job titles alone. The legal question is whether contractual terms are less favourable because of sex, and whether the employer has a lawful explanation for the difference.
For employees, the right evidence can turn an assumption into a well-founded claim. For employers, an early and disciplined review can prevent a pay concern becoming a lengthy tribunal dispute.
An equal pay claim example in practice
Consider a logistics business where a female Operations Co-ordinator earns £34,000. She manages staffing rotas, resolves customer issues, monitors compliance records and makes day-to-day decisions affecting delivery performance. A male Fleet Co-ordinator earns £39,000, along with a higher annual bonus opportunity.
The employer says the roles are different because one concerns people and customer operations, while the other concerns vehicles. That does not end the enquiry. The employee may argue that her work is like work, work rated as equivalent, or work of equal value to the male comparator’s role.
Like work means work that is the same or broadly similar, with any differences not being of practical importance. Work rated as equivalent applies where a job evaluation study has given the two jobs an equivalent score. Work of equal value can apply where the roles are different but make equivalent demands in areas such as skill, effort, knowledge, responsibility and working conditions.
If the roles are of equal value, the employee must also identify an actual comparator of the opposite sex who is, or was, employed in the same employment. This does not necessarily mean working at the same site. The question is often whether both roles are employed on common terms and conditions across the employer’s establishment or establishments.
In this example, the pay gap is not automatically unlawful. The employer may have evidence that the Fleet Co-ordinator role requires a specialist technical qualification, carries a genuine on-call obligation or was recruited during a documented skills shortage. Those factors may provide a defence, but they must be real, relevant and supported by evidence. A label such as “market rate” is not a complete answer without a clear account of how and why it was applied.
What an employee needs to establish
Equal pay claims arise under the Equality Act 2010. The law implies a sex equality clause into a contract of employment where a woman and a man are employed on less favourable terms and the legal tests are met. The principle applies equally to men who are paid less than an appropriate female comparator.
Pay is wider than basic salary. It can include overtime rates, bonuses, allowances, commission arrangements, holiday pay, contractual sick pay, pension benefits and other contractual terms. A claim may therefore arise even where two employees have the same headline salary.
A claimant does not need to prove that an employer consciously intended to pay less because of sex. They do, however, need a suitable comparator and a sound basis for saying that the work falls within one of the three legal categories. A hypothetical comparator will not usually be enough for an equal pay claim, although it may be relevant in a separate sex discrimination claim.
The distinction matters. Direct or indirect sex discrimination can address discriminatory pay decisions that do not fit the technical equal pay framework. The most suitable route depends on the facts, the available comparator and the remedy sought. In some cases, more than one type of claim should be considered.
Evidence that can support an equal pay claim
The most useful evidence is usually practical rather than dramatic. A current contract, payslips, bonus documents and pension information can establish the terms received by the claimant. Job descriptions, person specifications, appraisal documents, organisational charts and records of day-to-day duties can show what each role actually involves.
A job title should be treated with caution. Two people called managers may have very different levels of authority. Equally, an administrator and a co-ordinator may undertake work that is substantially alike. Tribunal cases often turn on the reality of the role, not the wording chosen by the employer.
Information about the comparator’s pay and terms may be harder to obtain. Employees should avoid accessing confidential records without authority. Instead, they can preserve legitimate documents already available to them, make a carefully framed written request or raise a formal grievance. If proceedings are started, disclosure obligations can require relevant documents to be produced.
Where a work of equal value claim is disputed, the tribunal may appoint an independent expert to assess the relative demands of the roles. This can make cases more detailed and time-consuming than a straightforward pay dispute. It also means an employer should not dismiss a concern simply because the jobs look different at first glance.
The employer’s material factor defence
Once a claimant has established an appropriate comparison, the employer may seek to show that the difference is due to a material factor unrelated to sex. The factor must be genuine and significant, rather than an explanation created after the event.
Length of service, experience, qualifications, geographic allowances, recruitment difficulties and objectively measured performance can sometimes be legitimate explanations. The evidence should show that the factor was applied consistently and actually influenced pay when the decision was made.
There is a further safeguard where an apparently neutral factor puts women, or men, at a particular disadvantage compared with the other sex. The employer may need to demonstrate that the factor is a proportionate means of achieving a legitimate aim. Put simply, there must be a sound business reason and the approach must go no further than reasonably necessary.
For employers, this is where pay structures, job evaluation systems and written decision records become valuable risk-management tools. Informal negotiations, discretionary allowances and historic “red-circle” arrangements can be difficult to defend years later if there is no reliable explanation for them.
Raising the issue before a tribunal claim
An employee may first wish to ask for clarity informally, particularly where a payroll error or unexplained allowance is suspected. A written request can identify the concern, the role used for comparison and the information needed to understand the difference. Keeping the tone factual is usually more effective than making accusations before the facts are known.
If the response is incomplete or unconvincing, a formal grievance may be appropriate. It should set out the contractual terms in question, the comparator, why the work is said to be comparable and the outcome sought. The employer should investigate properly, review relevant records and provide a reasoned response. A rushed or defensive process often increases legal and employee-relations risk.
Early advice is particularly valuable where a senior employee is considering a grievance alongside a settlement discussion. Communications, timing and the choice of legal claims can all affect negotiating position.
Time limits and practical next steps
Time limits in employment law are strict. An equal pay claim can normally be brought while employment continues, but the usual tribunal deadline after employment ends is six months less one day from the end of employment. Starting Acas early conciliation is generally required before presenting a tribunal claim and pauses the relevant limitation period.
This differs from many discrimination claims, which normally have a three-month less one-day time limit. The facts may support both an equal pay claim and a discrimination claim, so relying on the longer equal pay deadline without advice can be risky.
A successful claimant may seek arrears of pay and improved contractual terms. In England and Wales, arrears can generally go back up to six years, subject to the particular facts and statutory rules. The financial exposure can become substantial where a pay practice has continued over time or affects a group of staff.
Employers should respond by preserving relevant pay and job-evaluation records, checking whether comparable roles have been assessed consistently and avoiding any retaliatory treatment. Employees should keep contemporaneous documents, record key conversations and seek advice before deadlines approach.
Pay disputes are rarely only about the monthly figure. They can affect trust, progression, pension benefits and a person’s confidence in their employer. A clear assessment of the roles, the evidence and the available options gives both employees and employers the strongest basis for protecting their interests and resolving the issue with confidence.
