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

  1. Log the request and calculate the response deadline.
  2. Meet with the employee and consider reasonable alternatives.
  3. Check any separate reasonable-adjustment responsibilities.
  4. Confirm the outcome, reasons and next steps, updating contractual terms where agreed.
