Flexible Working Requests for Mental Health in the UK
15 August 2026
Learn how to request flexible working for mental health in the UK. Your rights, process, and tips for a successful application in 2026.
What is a Flexible Working Request and How Does It Relate to Mental Health?
A flexible working request is a formal application to change your work pattern, such as adjusting start and finish times, compressing hours, working from home, or job sharing. For many employees in the UK, flexible arrangements are not just a convenience—they can be essential for managing mental health conditions. For example, avoiding rush-hour commutes may reduce anxiety, while a later start can allow for better sleep if you experience depression or burnout. A successful request can also reduce stress triggers by giving you more control over your environment and schedule. Under UK law, you have the right to ask for flexible working, and employers must handle requests in a reasonable manner. This guide explains how to use that right effectively when mental health is your reason.
Your Legal Right to Request Flexible Working: Eligibility and Process
Since April 2024, all UK employees have the legal right to request flexible working from day one of employment, removing the previous 26-week qualifying period. This right applies to employees, not contractors or self-employed individuals. To make a statutory request, you must submit a formal written application (email is acceptable) explaining what change you want and, importantly, how it might affect your employer and colleagues. You can make only one statutory request every 12 months. Your employer must consider the request and respond within two months (reduced from three months under the 2024 reforms). They must notify you of their decision in writing. If they refuse, they must cite one of the eight permitted business reasons, such as cost burden or impact on quality or performance.
How to Make a Strong Case Linking Flexible Working to Your Mental Health
To increase your chances of approval, frame your request around how the change will help you perform your role effectively rather than solely focusing on your illness. Start by describing your mental health condition objectively—whether it's anxiety, depression, PTSD, or stress—and explain the specific work-related challenges you face. For example: 'A 10am start helps me manage morning anxiety and ensures I'm focused during core hours.' Also suggest trial periods, measurable outcomes, and ways to maintain communication. Offer to review the arrangement after three or six months. If your condition meets the Equality Act 2010 definition of disability, you can also ask for the same flexible working pattern as a 'reasonable adjustment'—and this is a stronger legal lever because employers must make adjustments for disabled employees.
What Employers Must Consider and How They Should Respond
When you submit a flexible working request, your employer must follow a statutory procedure: they must consider the application fairly and only refuse for one of eight permitted business reasons, including extra costs, inability to reorganise work among staff, detrimental impact on ability to meet customer demand, or insufficient work during the proposed times. They should also assess the impact on the wider team and consider alternatives. Under the Equality Act 2010, if your mental health condition amounts to a disability, refusing a flexible working request could amount to unlawful discrimination, unless there is a strong business case. Your employer must also allow you to appeal a rejection. Keep records of all communication, as you may need to raise a grievance or take a claim to an employment tribunal if you believe the decision was unfair or discriminatory.
Additional Support: Reasonable Adjustments, Occupational Health, and Where to Get Help
Beyond a formal flexible working request, you can seek support through workplace reasonable adjustments. If your mental health condition is recognised as a disability, your employer has a duty to reduce any substantial disadvantage you face. This might include changes to your desk location, regular breaks, or providing a mentor. Occupational health assessments can provide evidence and recommendations to strengthen your case. For free and confidential advice, UK employees can contact the Acas helpline (0300 123 1100) or Mind's 'Ways to Wellbeing' resources. If your employer refuses a request unreasonably, you can raise a grievance or, in disability cases, claim discrimination at an employment tribunal within three months of the decision. Remember to seek support early—most employers are willing to explore solutions if you communicate clearly and professionally.
