Who is eligible for flexible working rights in the UK? Clear explanation of day-one employment rights, employer obligations, request procedures, and Employment Tribunal claims under UK employment law in England and Wales.

Flexible working rights in the UK allow employees to request changes to their working pattern, such as altering hours, working remotely, or adjusting start and finish times. These rights are governed primarily by the Employment Rights Act 1996 as amended by the flexible working reforms introduced under the Employment Relations (Flexible Working) Act 2023.
Flexible working is not an automatic entitlement to work flexibly. Instead, it is a statutory right to request flexible working arrangements, which employers must consider in a reasonable manner. Eligibility rules determine who can make such a request and how often it can be made.
What Is Flexible Working?
Flexible working refers to any arrangement that changes the standard working pattern. Common examples include:
- Part-time working
- Job sharing
- Remote or hybrid working
- Compressed hours (full-time hours over fewer days)
- Flexitime (variable start and finish times)
- Annualised hours contracts
The key feature is flexibility in when, where, or how work is performed, subject to employer agreement.
Who Is Eligible to Request Flexible Working?
1. All Employees from Day One
Following recent legal reforms, the right to request flexible working is now a day-one employment right. This means:
- Employees do not need a minimum period of service
- New starters can make a request immediately
- The right applies from the first day of employment
This marks a significant change from the previous 26-week qualifying period.
2. Employees Only (Not Workers)
The statutory right applies specifically to employees. This includes:
- Full-time employees
- Part-time employees
- Fixed-term employees
It does not automatically extend to:
- Self-employed contractors
- Some freelancers
- Genuine independent contractors
However, eligibility can depend on whether an individual is legally classified as an employee under employment status tests.
3. Agency Workers (Limited Rights)
Agency workers generally do not have the full statutory right to request flexible working from the end client. However:
- They may be able to request flexibility through the agency
- Some arrangements depend on contract terms and assignment structure
- Rights may vary depending on employment status with the agency itself
4. Employees Returning from Leave
Employees returning from statutory leave are eligible to request flexible working, including:
- Maternity leave
- Paternity leave
- Adoption leave
- Shared parental leave
Flexible working is often used to support return-to-work arrangements, although it is not automatically granted.
How the Legal Right to Request Flexible Working Works
Eligibility provides the right to make a request, not to automatically receive flexible working.
Employers must:
- Deal with requests in a reasonable manner
- Consult with the employee where necessary
- Make a decision within a statutory timeframe
- Only refuse for one or more valid business reasons
Valid refusal reasons include:
- Additional costs
- Impact on performance or quality
- Inability to reorganise work among staff
- Detrimental effect on customer demand
- Insufficient work during proposed hours
- Planned structural changes
Frequency of Requests
Employees can usually make up to two flexible working requests in any 12-month period. This prevents repeated or overlapping applications but still allows flexibility over time.
Types of Flexible Working Eligible Employees Can Request
Eligible employees can request a wide range of changes, including:
Changes to hours
- Reduced working hours
- Compressed hours
- Flexible start and finish times
Changes to location
- Homeworking
- Hybrid working arrangements
- Remote-first roles
Changes to working pattern
- Job sharing
- Rotational schedules
- Annualised hours
Each request must be considered on its own merits.
Employer Obligations in Assessing Eligibility-Based Requests
Once a request is made, employers must follow a statutory process:
- Acknowledge and consider the request
- Assess business impact
- Consult with the employee where appropriate
- Provide a decision within two months (unless extended by agreement)
Employers cannot reject requests arbitrarily. Decisions must be based on legitimate business grounds.
Refusal of Flexible Working Requests
Even where an employee is eligible, employers can refuse requests if they can show:
- The role cannot be performed flexibly
- Costs would be unreasonable
- Staffing or operational issues would arise
- Customer service or performance would be affected
The employer must explain the reason for refusal clearly.
Protection Against Detriment or Dismissal
Employees are protected from:
- Being dismissed for making a flexible working request
- Being treated unfairly or disadvantaged because they made a request
- Retaliation or negative treatment linked to exercising the right
Such conduct may give rise to claims in an Employment Tribunal.
Employment Tribunal Claims
Employees may bring claims where:
- A flexible working request was not dealt with properly
- The employer failed to follow the statutory procedure
- The refusal was based on incorrect or unfair grounds
- The employee suffered detriment for making a request
Time limits are generally:
- 3 months less one day from the date of the employer's decision or act complained of
- ACAS Early Conciliation is required before submitting a claim
Common Misunderstandings
“Flexible working must be granted”
Incorrect. Employees only have a right to request, not a right to approval.
“Only parents can apply”
Incorrect. The right applies to all eligible employees from day one.
“Employers can ignore requests”
Incorrect. Employers must consider and respond within the legal framework.
“Requests must be permanent”
Not necessarily. Requests can be temporary or trial-based.
Practical Importance
Flexible working eligibility plays a central role in modern UK employment law. It supports:
- Work-life balance
- Retention of staff
- Return-to-work after leave
- Adaptation to disability or health needs
- Operational flexibility for employers
It also forms part of wider workplace rights enforcement through Employment Tribunals.
Key Takeaways
Eligibility for flexible working rights in the UK applies to all employees from the first day of employment. The right allows employees to request changes to their working hours, location, or pattern, but does not guarantee approval. Employers must consider requests reasonably and can only refuse them for valid business reasons. Agency workers and contractors have more limited rights depending on their status. Failure to properly handle requests may lead to Employment Tribunal claims.
