Guidance for England, Scotland and Wales. Northern Ireland employment rules can differ.
What a statutory request contains
Flexible working can concern hours, working days, start and finish times or location. The employee's written request should say it is a statutory request, describe the change and proposed start date, and give the date of any previous request.
An employee can make two statutory applications in a 12-month period. Record the date received and the decision deadline immediately; informal conversations should not cause a formal request to disappear from the process.
Discuss the proposal before refusing
Employers must handle requests reasonably and discuss a request with the employee before refusing it. Consider the practical impact and possible alternatives rather than relying on a general preference for existing working patterns.
A disability-related request may also engage the separate duty to make reasonable adjustments. Do not assume that considering it only under the flexible working procedure settles that duty.

Give a reasoned written outcome
The normal decision period is two months from the request, unless a longer period is agreed. If accepted, confirm the change and start date, and update the contract as soon as possible and no later than 28 days after approval.
A refusal must rely on one or more permitted business reasons, such as a damaging cost burden, inability to reorganise work or a detrimental effect on quality, performance or customer demand. Explain how the reason applies to the actual proposal and offer an appeal process.
In practice
A four-day pattern needs an actual assessment
An employee requests a change in working days. The manager discusses customer cover, handovers and the work that must happen on the proposed non-working day, then explores whether another pattern or a trial could address the concern.
The outcome records the evidence and any agreed terms. If a trial is used, the parties should be clear about its duration, review and what happens afterwards.
Your next steps
- Log the request and calculate the response deadline.
- Meet with the employee and consider reasonable alternatives.
- Check any separate reasonable-adjustment responsibilities.
- Confirm the outcome, reasons and next steps, updating contractual terms where agreed.
