Employment Law – Sexual Orientation Discrimination

The Equality Act 2010 makes it unlawful to discriminate against someone at work because of their sexual orientation.

Sexual orientation is one of the protected characteristics under the Equality Act.

Protection can apply throughout the employment relationship, including:

Recruitment
Terms and conditions
Pay and benefits
Training
Promotion
Transfers
Performance management
Disciplinary action
Redundancy
Dismissal
Certain post-employment treatment

There is no minimum period of employment required before someone can bring a genuine sexual orientation discrimination claim.

How is Sexual Orientation Defined Under the Equality Act?

The Equality Act defines sexual orientation as a person's sexual orientation towards:

People of the same sex
People of the opposite sex
People of either sex

This covers sexual orientations including:

Gay
Lesbian
Heterosexual
Bisexual

The terminology people use to describe their sexuality can be wider and may change over time.

Equality Act protection can also apply where someone is treated unlawfully because of the sexual orientation an employer believes they have, whether or not that assumption is correct.

What is Sexual Orientation Discrimination?

Sexual orientation discrimination occurs where someone experiences unlawful treatment because of:

Their Actual sexual orientation
Their Perceived sexual orientation
The Sexual orientation of someone with whom they are associated

Sexual orientation discrimination can generally take four principal forms:

Direct discrimination
Indirect discrimination
Harassment
Victimisation

For further general guidance, see Discrimination.

Who is Protected by the Equality Act?

Equality Act employment protection is wider than permanent employees.

Depending on the particular working relationship, it can protect:

Employees
Workers
Job applicants
Agency workers
Contractors required personally to perform work
Certain self-employed people personally providing services
Apprentices and trainees
Office holders
Partners
Former employees in relation to certain post-employment matters

A genuinely independent self-employed business will not automatically receive employment protection merely because it provides services to another organisation.

The legal relationship and the particular Equality Act provisions will need to be considered.

Direct Sexual Orientation Discrimination

Direct discrimination occurs where someone is treated less favourably because of sexual orientation than another person is, or would be, treated in materially similar circumstances.

For example, an employer could potentially directly discriminate if it refuses to promote a lesbian employee because of her sexual orientation.

The same principle protects people of any sexual orientation.

It would therefore also be unlawful to disadvantage someone because they are:

Gay
Lesbian
Bisexual
Heterosexual

What is Discrimination by Perception?

Direct discrimination can occur even where the employer is wrong about someone's sexual orientation.

This is commonly known as discrimination by perception.

For example, an employer might refuse to recruit a woman because it incorrectly assumes that she is bisexual.

The fact that the employer's assumption was wrong does not prevent the treatment from potentially being unlawful.

The relevant question is whether the less favourable treatment occurred because of the perceived sexual orientation.

What is Discrimination by Association?

Direct discrimination can also arise because of your association with someone of a particular sexual orientation.

For example, an employee might be treated less favourably because:

Their Son is gay
Their Partner is bisexual
They regularly support an LGBT+ family member

You do not personally need to share the sexual orientation concerned.

Can Direct Sexual Orientation Discrimination Be Justified?

Ordinary direct sexual orientation discrimination cannot generally be objectively justified by arguing that the employer had a good business reason.

This differs from indirect discrimination.

However, the Equality Act contains limited statutory exceptions, including genuine occupational requirements in appropriate circumstances.

Indirect Sexual Orientation Discrimination

Indirect discrimination can occur where an employer applies a provision, criterion or practice, commonly called a PCP, to everyone but it places people of a particular sexual orientation at a particular disadvantage.

The rule may appear neutral.

For example, an employer might operate a benefit scheme that provides a particular benefit to married opposite-sex spouses but unjustifiably excludes equivalent same-sex spouses or civil partners.

A workplace rule can therefore potentially be indirectly discriminatory even though it does not expressly mention sexual orientation.

Other examples could involve policies concerning:

Benefits
Leave
Working arrangements
Recruitment
Staff facilities

Whether unlawful indirect discrimination has occurred will depend on the particular facts.

Can Indirect Discrimination Be Justified?

Yes.

An employer can potentially defend indirect discrimination if it establishes that the PCP is a:

Proportionate means of achieving a legitimate aim

The employer should normally identify a genuine legitimate objective and show that the measure used is proportionate.

Relevant questions can include:

What objective the employer is trying to achieve
Whether the rule actually contributes to that objective
How serious the disadvantage is
Whether a less discriminatory alternative was reasonably available

The employer must establish objective justification rather than simply assert that the rule is convenient.

Can Someone Who Does Not Share the Sexual Orientation Still Bring an Indirect Discrimination Claim?

Potentially, yes.

Since 1 January 2024, the Equality Act also protects someone in certain circumstances where they do not personally share the relevant protected characteristic but are subjected to substantively the same disadvantage as the group that does.

For example, if a workplace PCP particularly disadvantages people of a particular sexual orientation and another employee who does not share that orientation experiences substantively the same disadvantage, the newer statutory provisions can potentially apply.

The specific legal requirements must still be satisfied.

Harassment Related to Sexual Orientation

Harassment occurs where there is unwanted conduct related to sexual orientation that has the purpose or effect of:

Violating someone's dignity
Creating an intimidating environment
Creating a hostile environment
Creating a degrading environment
Creating a humiliating environment
Creating an offensive environment

Examples can potentially include:

Homophobic language
Derogatory jokes
Offensive comments
Threats
Abusive messages
Deliberately outing someone's sexual orientation
Persistent offensive stereotypes

The conduct does not need to involve physical behaviour.

It can take place through:

Conversations
Emails
Messaging services
Social media
Work-related online communications

Does Harassment Have to Be Intentional?

No.

A person can potentially commit unlawful harassment even if they say they did not intend to cause offence.

Where the issue concerns the effect of the conduct, an Employment Tribunal considers:

The Claimant's perception
The Other circumstances
Whether it was reasonable for the conduct to have that effect

Intent is therefore relevant but is not decisive.

Does the Harassment Have to Be Directed at You Personally?

No.

A general workplace culture can potentially amount to harassment.

For example, repeated homophobic jokes or derogatory comments made openly in an office could potentially create an intimidating, hostile, degrading, humiliating or offensive environment even where the comments were not directly addressed to the person bringing the complaint.

A person also does not necessarily need to have the sexual orientation being targeted.

For example, someone wrongly believed to be gay may be protected.

Does Ordinary Bullying Automatically Amount to Sexual Orientation Harassment?

No.

Unreasonable criticism or excessive monitoring might amount to bullying, but it does not automatically become harassment under the Equality Act.

For sexual orientation harassment, the unwanted conduct must be sufficiently related to sexual orientation.

For example, aggressive criticism could potentially become relevant if it is accompanied by homophobic comments or evidence showing that the treatment is related to the employee's sexual orientation.

What About Harassment by Customers or Other Third Parties?

The law in this area is changing.

As at 10 September 2026, an employer will not generally be automatically liable under the Equality Act merely because a third party harasses a worker because of sexual orientation.

Third parties can include:

Customers
Clients
Patients
Service users
Suppliers
Contractors
Members of the public

The old statutory rule sometimes referred to as the three-strikes rule, which concerned repeated third-party harassment, was repealed and is no longer current law.

However, an employer should still take complaints seriously.

Its own actions or failures in response to third-party harassment can also create separate legal issues depending on the circumstances.

How is Third-Party Harassment Law Changing?

From 30 October 2026, the Employment Rights Act 2025 will introduce wider employer liability for third-party harassment.

From that date, an employer can be liable where a third party harasses a worker in the course of employment unless the employer can establish that it took all reasonable steps to prevent the harassment.

This includes harassment related to sexual orientation.

Employers should therefore consider measures such as:

Assessing third-party harassment risks
Providing reporting procedures
Training employees and managers
Recording incidents
Addressing problem customers or clients
Reviewing relevant contractual arrangements

This new liability has not yet taken effect as at 10 September 2026.

Victimisation

Victimisation occurs where someone suffers a detriment because they have done, or the employer believes they have done or may do, a protected act under the Equality Act.

Protected acts can include:

Bringing Equality Act proceedings
Giving evidence in discrimination proceedings
Supporting another person's discrimination complaint
Raising a grievance alleging discrimination
Making an allegation that the Equality Act has been breached

For example, an employee might support a colleague who has complained of homophobic harassment and subsequently be denied promotion because they supported the complaint.

There is no requirement to compare the treatment with another employee who did not make or support a complaint.

False evidence or allegations made in bad faith do not normally qualify as protected acts.

Who Can Be Liable Under the Equality Act?

Liability for sexual orientation discrimination can potentially arise against:

The Employer
The Individual who committed the discrimination
Another legally responsible person

An employer can be vicariously liable for discriminatory acts committed by its employees in the course of employment.

This can include conduct occurring at:

The Workplace
Work social events
Business trips
Work-related online communications

Whether particular conduct occurred in the course of employment will depend on its connection with work.

The individual who discriminated can also potentially be personally liable.

Does the Employer Have to Know About the Discrimination?

Not necessarily.

An employer can potentially be vicariously liable even if senior management:

Did not authorise the conduct
Did not know it was happening
Would have disapproved of it

The relevant issue is whether the employee committed the unlawful act in the course of employment.

Does an Employer Have a Defence?

Potentially.

An employer may avoid vicarious liability if it proves that it took all reasonable steps to prevent the employee from committing the discrimination or acts of that description.

Relevant preventative measures can include:

Effective equality policies
Appropriate training
Refresher training
Effective reporting procedures
Proper investigation of complaints
Enforcement of workplace standards

Simply having a policy that is not implemented will not necessarily establish the defence.

Exceptions Under the Equality Act

There are limited circumstances in which treatment that would otherwise appear to involve a protected characteristic can be lawful.

These exceptions should generally be interpreted carefully.

Occupational Requirements

In limited circumstances, having a particular sexual orientation can be a genuine occupational requirement for a particular job.

The employer must show that:

The Requirement genuinely relates to the nature or context of the work
Applying it is a proportionate means of achieving a legitimate aim

For example, in particular circumstances a specialist service supporting gay or lesbian users may be able to establish a genuine occupational requirement for a role where lived experience connected with sexual orientation is genuinely necessary.

However, an employer cannot normally restrict a role to a particular sexual orientation simply because:

Customers prefer it
The Employer assumes one orientation would perform better
It wishes to create a particular image

The requirement must relate genuinely to the work and satisfy the proportionality test.

Positive Action

The Equality Act allows employers to take certain forms of positive action to address disadvantage or under-representation.

For example, where an employer reasonably thinks that people of a particular sexual orientation:

Experience a disadvantage
Have different needs
Are disproportionately under-represented

it may in appropriate circumstances take proportionate steps to encourage participation or reduce the disadvantage.

This might include:

Targeted outreach
Encouraging applications
Training opportunities
Development programmes

There is no requirement that the employer first establish under-representation during a particular 12-month period.

Can Sexual Orientation Be Used to Decide Who Gets a Job?

Only in very limited circumstances.

Separate positive-action rules can potentially allow an employer to use a protected characteristic as a tie-break when choosing between candidates who are genuinely of equal merit and the statutory conditions are satisfied.

This does not permit employers to:

Operate automatic quotas
Always prefer LGBT+ applicants
Reject a better candidate merely because of sexual orientation

Positive action and unlawful positive discrimination are not the same thing.

Overseas Employment

The Equality Act does not contain a simple rule stating that it applies only to employees working at establishments physically located in Great Britain.

International employment cases require a more detailed territorial analysis.

A worker based and working in Great Britain will ordinarily be within the scope of British employment legislation.

Where someone works abroad, the question can depend on whether their employment has a sufficiently strong connection with:

Great Britain
British employment law

Relevant circumstances can potentially include:

Where the employee is based
Where the work is carried out
Which business they work for
How employment is managed
The Overall connection with Great Britain

An employee who genuinely lives and works abroad will generally find it more difficult to establish Equality Act jurisdiction merely because their employer is British.

However, overseas employment is not automatically excluded.

For further guidance, see International Employment.

Can I Send a Discrimination Questionnaire to My Employer?

The Equality Act previously contained a formal statutory questionnaire procedure.

That statutory procedure was abolished on 6 April 2014.

It is therefore outdated to suggest that employees can still serve the old statutory Equality Act questionnaire and automatically obtain the former procedural consequences.

However, you can still ask your employer relevant questions about suspected discrimination.

For example, you might reasonably ask for an explanation of:

Recruitment criteria
Promotion decisions
Selection procedures
Pay decisions

Relevant responses or failures to provide an adequate explanation may form part of the wider evidence considered in a dispute.

However, there is no longer an automatic statutory questionnaire regime under which failure to answer by itself creates the former consequences.

How Do You Prove Sexual Orientation Discrimination?

Direct evidence of discrimination is relatively uncommon.

Employers rarely state openly that a decision was made because someone is:

Gay
Lesbian
Bisexual
Heterosexual

An Employment Tribunal may therefore have to consider the surrounding circumstances and draw appropriate inferences from proven facts.

Relevant evidence can include:

Emails
Messages
Comments
Recruitment records
Promotion records
Performance documents
Treatment of comparable employees
Witness evidence
Changes in the employer's explanation

How Does the Burden of Proof Work?

The Equality Act contains a two-stage burden-of-proof framework.

Initially, the claimant must establish facts from which the Tribunal could decide, in the absence of another explanation, that unlawful discrimination occurred.

It is not enough simply to allege discrimination.

If sufficient facts are established, the burden shifts to the respondent to prove that unlawful discrimination did not occur.

The Tribunal decides disputed facts on the balance of probabilities.

What Inferences Can a Tribunal Draw?

A Tribunal can consider the entire factual picture.

For example, relevant circumstances might include:

Homophobic comments by a decision-maker
A Sudden unexplained change in treatment
Inconsistent recruitment criteria
Less qualified comparators being promoted
Changing explanations for dismissal
Departure from normal procedures

If the employer provides a credible, evidence-based non-discriminatory explanation, the claim may fail.

If the explanation is inconsistent or unsupported, that can potentially contribute to an inference of discrimination.

Raising a Grievance

If you remain employed, you may wish to raise the matter informally where appropriate.

If it cannot be resolved, you can raise a formal Grievance at Work.

A grievance should normally explain:

What happened
When it happened
Who was involved
Why you believe sexual orientation was relevant
What evidence is available
What outcome you are seeking

Your employer should take the complaint seriously and investigate it fairly and without unreasonable delay.

You do not need to leave your employment before bringing a sexual orientation discrimination claim.

Do I Have to Finish the Grievance Process Before Going to Tribunal?

No.

An internal grievance can be important, but you do not normally have to wait for:

The Grievance outcome
An Appeal
An Internal investigation

before protecting your Employment Tribunal position.

Internal procedures do not normally stop the statutory Tribunal deadline.

Acas Early Conciliation has separate rules affecting calculation of the limitation period.

If you have already been dismissed, you may potentially bring:

A Sexual orientation discrimination claim
An Unfair dismissal claim where the relevant requirements are satisfied

A discrimination claim does not require the ordinary unfair dismissal qualifying period.

Remedies

If an Employment Tribunal finds that unlawful sexual orientation discrimination occurred, it can potentially:

Make a Declaration
Award Compensation
Make an Appropriate recommendation

Declaration

A declaration records the legal rights of the parties and the Tribunal's findings.

Compensation

Compensation is intended, so far as money can do so, to compensate for the loss and harm caused by unlawful discrimination.

Recommendation

A Tribunal can make an appropriate recommendation requiring the respondent to take specified steps within a particular period to reduce the adverse effect of the discrimination on the claimant.

Compensation for Sexual Orientation Discrimination

There is no general statutory ceiling on compensation for sexual orientation discrimination.

Depending on the circumstances, compensation can include:

Past loss of earnings
Future loss of earnings
Lost benefits
Lost pension
Lost bonus or commission
Injury to feelings
Psychiatric or physical injury where established
Aggravated damages in appropriate cases
Interest

A claimant is normally required to take reasonable steps to reduce or mitigate continuing financial loss.

Injury to Feelings

An injury-to-feelings award compensates for the emotional impact of discrimination.

This can include:

Humiliation
Distress
Anxiety
Upset
Loss of confidence
Emotional suffering

Employment Tribunals use the Vento bands as guidance.

For claims presented on or after 6 April 2026, the current bands are:

Lower band – £1,300 to £12,600
Middle band – £12,600 to £37,700
Upper band – £37,700 to £62,900

The most exceptional cases can justify an award exceeding £62,900.

The appropriate award depends on the actual effect of the discrimination rather than simply the number of incidents.

Time Limits

Employment Tribunal time limits are strict.

As at 10 September 2026, most sexual orientation discrimination claims must generally be started within:

3 months minus 1 day

from the discriminatory act complained about.

Before presenting most Employment Tribunal claims, you must normally notify Acas and begin Early Conciliation.

Notifying Acas within the relevant limitation period can pause the limitation clock and affect the final deadline.

For further guidance, see Employment Tribunal Proceedings.

What if the Discrimination Continued Over a Period of Time?

Conduct extending over a period can potentially be treated as occurring at the end of that period.

For example, this may apply to:

An Ongoing discriminatory policy
A Continuing discriminatory practice
A Connected course of discriminatory conduct

However, separate discriminatory decisions do not automatically become one continuing act merely because they involve the same employee or protected characteristic.

Whether the conduct amounts to a continuing act will depend on the facts.

For further guidance, see Continuing Acts of Discrimination.

Are Tribunal Time Limits Changing?

Yes.

From 1 October 2026, the time limit for most Employment Tribunal claims will increase to:

6 months minus 1 day

The new period applies where the relevant limitation period starts on or after 1 October 2026.

Where the time limit began before that date, the previous rules will generally continue to apply.

You should therefore calculate the actual deadline rather than assume that every existing claim automatically receives six months.
