The practice of treating a person more favorably in recruitment or employment specifically because they possess a protected characteristic, which is generally unlawful in the UK under the Equality Act 2010, with very limited exceptions.
Key Takeaways
Positive discrimination is treating someone more favorably in employment specifically because they have a protected characteristic. In the UK, this is unlawful. The Equality Act 2010 protects against discrimination in both directions: you can't disadvantage someone because of a protected characteristic, and you can't advantage them because of one either. The confusion between positive discrimination and positive action is widespread. A 2023 CIPD survey found that 73% of UK employers couldn't accurately define the difference. The distinction matters because getting it wrong exposes organizations to discrimination claims from candidates or employees who were passed over. Here's the simplest way to understand it: if you select a candidate primarily because of their protected characteristic, that's positive discrimination and it's unlawful. If you take steps to encourage applications from underrepresented groups and then select the best candidate, that's positive action and it's lawful. The line between them is narrower than most people think.
UK equality law operates on a principle of individual merit with adjustments for structural disadvantage, not group-based preferential treatment.
The Equality Act 2010 prohibits direct discrimination, which means treating someone less favorably because of a protected characteristic. If an employer selects Candidate A over equally qualified Candidate B specifically because Candidate A is female, Candidate B has been directly discriminated against on grounds of sex. The fact that the employer's intention was to improve gender diversity doesn't change the legal analysis. Good motives don't make direct discrimination lawful.
A quota system that reserves specific positions or percentages for people with a particular characteristic is positive discrimination. If a company says "30% of our graduate intake must be from ethnic minority backgrounds," that's a quota. It means a white candidate could be rejected despite being better qualified, solely because the quota has been filled. UK courts have consistently struck down quota systems as direct discrimination. This contrasts with some EU countries (Norway, France, Germany) where quota laws for gender on boards exist.
Section 159 of the Equality Act allows one limited form of what looks like positive discrimination: the tiebreaker provision. Where two candidates are "as qualified as each other," the employer may choose the candidate from an underrepresented group. But the conditions are strict. The candidates must be genuinely equally qualified (not "close enough"). The employer must reasonably think people with that characteristic are underrepresented or disadvantaged. And it can't be a blanket policy. Every case must be considered on its individual facts. In practice, very few employers use Section 159 because the risk of getting the "equally qualified" assessment wrong is significant.
This is the most misunderstood distinction in UK equality law. Getting it right is essential for any diversity initiative.
| Dimension | Positive Discrimination (Unlawful) | Positive Action (Lawful) |
|---|---|---|
| Selection basis | Selects based on protected characteristic | Selects based on merit, after encouraging wider participation |
| Legality | Unlawful under the Equality Act 2010 | Lawful under Sections 158 and 159 of the Equality Act |
| Example in hiring | "We'll hire the female candidate because we need more women" | "We'll advertise in publications that reach more female candidates and encourage women to apply" |
| Quotas | Sets fixed targets that must be met by selecting from specific groups | Sets aspirational targets as benchmarks, not binding requirements |
| Training | "Only ethnic minority employees can attend this leadership program" | "We'll offer additional mentoring to ethnic minority employees to address underrepresentation in senior roles" |
| Tiebreaker | "Always choose the minority candidate when candidates are close in quality" | "Where candidates are genuinely equally qualified, we may consider underrepresentation as a factor in the specific case" |
| Risk level | High. Claims from candidates passed over are straightforward. | Low to moderate when properly documented and case-by-case. |
Employment tribunals and courts have shaped the boundary between lawful and unlawful positive measures through specific rulings.
Cheshire Police lowered the pass mark for female and ethnic minority applicants in a recruitment exercise. The Employment Appeal Tribunal ruled this was unlawful positive discrimination. The force's intent to diversify its ranks didn't justify treating candidates differently based on protected characteristics at the selection stage.
While not a UK case, the EFTA Court ruled that Norway's academic gender quotas were disproportionate because they automatically preferred one sex without individual assessment. This reasoning aligns with UK law's insistence that selection must involve individual consideration, not blanket group-based preference.
The Labour Party's policy of all-women shortlists for parliamentary selections was ruled unlawful sex discrimination. Parliament later passed the Sex Discrimination (Election Candidates) Act 2002 specifically to create a political exception. This exception doesn't extend to employment. The case illustrates that even well-intentioned positive discrimination requires specific legislation to be lawful.
These scenarios regularly arise in organizations trying to improve diversity without fully understanding the legal boundaries.
Setting a target of "40% female leadership by 2030" is lawful as an aspiration that drives outreach, development programs, and pipeline building. It becomes unlawful when managers interpret it as "promote women over equally or better qualified men until we hit 40%." The problem is often in implementation, not the target itself. HR teams must clearly communicate that targets are benchmarks, not mandates for individual selection decisions.
An employer who says "this leadership program is only open to Black employees" is engaging in positive discrimination. The lawful approach under Section 158: offer additional mentoring, coaching, or encouragement to Black employees to address their underrepresentation in leadership, while keeping the formal program open to all eligible employees.
Guaranteeing interviews to all applicants from a specific group ("we interview every disabled applicant") is lawful and encouraged under the Disability Confident scheme. But guaranteeing the job is positive discrimination. The interview guarantee is a positive action measure that gives underrepresented candidates a fair chance. The hiring decision must still be based on merit.
UK employers can take meaningful steps to improve diversity without crossing into unlawful territory. These approaches are all supported by the Equality Act's positive action provisions.
