Flexible Working Application Letter UK: Your 2026 Step-by-Step Guide
11 August 2026
How to write a flexible working application letter in the UK. Free template, legal rights, and tips for a successful request in 2026.
Know Your UK Legal Right to Flexible Working
Since 6 April 2024, every UK employee has the right to request flexible working from day one of employment – no more 26-week qualifying period. This includes part-time hours, flexitime, compressed hours, job sharing, and hybrid work. Your employer must consider your request fairly, hold a consultation meeting if needed, and notify you of their decision within two months. They can only reject your application for one of eight lawful business reasons, such as cost burden or negative impact on performance. Knowing this strengthens your letter and gives you the confidence to make a well-grounded request in 2026.
What to Include in Your Flexible Working Letter
A strong UK flexible working application letter should be clear, professional, and focused. Start with your full name, role, and date, followed by your employer's address. State upfront that you are making a statutory request under the Employment Rights Act 1996. Specify exactly what change you want – for example, “work 9:00am to 2:30pm Monday to Friday” or “condense my hours into four days”. Provide a proposed start date and explain how the change will affect your work, your team, and your customers. Keep the tone cooperative, not demanding, and invite discussion.
How to Build a Compelling Business Case
To maximise your chances of approval, focus on how flexible working benefits the business, not just you. Explain how your productivity will stay constant or improve, and how you will maintain communication with colleagues and clients. For example, state that you will overlap core hours, attend regular video meetings, or use shared project tools to stay visible. Mention any positive outcomes you have already achieved under an informal arrangement. Address possible concerns proactively, such as covering customer calls or being available for urgent queries. A thoughtful business case shows your employer you have considered the practicalities in advance.

Here is a proven template that meets UK statutory requirements. Address it to your line manager or HR and send it by email with a read receipt. Use your own words and adapt it to your situation. Dear [Manager's Name], Re: Statutory Flexible Working Request – [Your Name] I am writing to formally request flexible working in accordance with the Employment Rights Act 1996. Specifically, I would like to change my working pattern to [e.g., start at 10:00 and finish at 16:00, Monday to Friday, from 1 September 2026]. This change will not impact performance. I will continue to attend all meetings and be available during core hours [e.g., 10:00–15:00]. It will help me reduce my commute and improve work-life balance, while maintaining my output. I am happy to meet to discuss this further. Thank you for considering my request. Yours sincerely, [Your name]
What Happens After You Submit Your Letter
Once your employer receives your flexible working request, they must respond within two months. They may invite you to a consultation meeting to discuss your proposal, and you have the right to be accompanied by a workplace colleague or union representative. They can accept it, reject it, or suggest alternative arrangements. If they reject it, they must provide a written explanation citing one of the eight statutory reasons. You can then appeal the decision. If the appeal is also rejected, you may be able to bring a claim to an employment tribunal within three months minus one day. Keep records of all correspondence.
