Flexible Working Process Pack (England & Wales)
A statutory flexible working request follows a specific sequence: your request, the employer's acknowledgement, and the employer's outcome decision — with a statutory 2-month deadline in between. Each document below is a faithful, diff-verified reproduction of the corresponding ACAS flexible working letter templates. Read the step-by-step guide for how these fit together.

Flexible working is a change to when, where or how an employee works — for example part-time hours, hybrid or home working, compressed hours, or flexitime. Since 6 April 2024, the right to make a statutory flexible working request is a day-one right for employees (no qualifying period), and employers must follow a fair process set out in law and the Acas Code of Practice on requests for flexible working. The Flexible Working Process Pack (England & Wales) gives employers the documents to handle a request correctly — acknowledging it, arranging a consultation, and giving the decision (or dealing with an appeal) — within the legal time limit.
- An employee has made (or is about to make) a statutory flexible working request.
- You want to handle it fairly, in line with the Acas Code, and within the two-month time limit.
- You need the letters to acknowledge the request, invite the employee to a consultation, and confirm the outcome or an appeal.
- You (the employer) are proposing to change someone's working arrangements — that is a contract variation, not an employee's statutory flexible working request, and needs a different approach.
- The request is really a disability-related adjustment. A disabled employee asking to change how they work may trigger the duty to make reasonable adjustments under the Equality Act 2010 — a stronger, separate duty. Use the Reasonable Adjustments Process Pack and take advice; don't treat it as an ordinary flexible working request.
- The arrangement is a purely informal, temporary agreement both sides are happy with and neither wants to treat as a formal statutory request.
- 1
Receive the statutory request
It should be in writing, dated, and state that it is a statutory flexible working request and the change the employee wants.
- 2
Deal with it reasonably and consult the employee
Discuss the request and explore alternatives before making a decision.
- 3
Decide within two months of receiving the request
Including any appeal, unless you agree a longer period in writing.
- 4
Only refuse for one of the eight statutory business reasons
(below), and explain the decision.
- 5
Confirm the outcome in writing
If agreed, it is normally a permanent change to the contract, unless you agree otherwise or a trial period.
- 6
Offer an appeal
Good practice under the Acas Code.
- Day-one right: Since 6 April 2024, employees can make a statutory flexible working request from their first day — no minimum service is required.
- Two requests a year: An employee can make up to two statutory requests in any 12-month period.
- Two-month decision deadline: You must give your decision, including any appeal, within two months of receiving the request, unless an extension is agreed in writing.
- The eight statutory business reasons for refusal (ERA 1996, s.80G): You may only refuse for one or more of: the burden of additional costs; detrimental effect on ability to meet customer demand; inability to reorganise work among existing staff; inability to recruit additional staff; detrimental impact on quality; detrimental impact on performance; insufficiency of work during the periods the employee proposes to work; and planned structural changes.
- Consult before deciding: Before refusing a statutory request, employers should consult with the employee to discuss the request and consider possible alternatives, in line with the statutory procedure and the Acas Code.
- Note on future reform: Under the Employment Rights Act 2025, a new "reasonableness" requirement for refusing a request has been legislated but is not yet in force. This pack follows the current in-force law and supports evidence-based, well-documented decisions in line with best practice.
- Do employees have the right to request flexible working?
- Yes. Employees have a statutory right to request flexible working, and since 6 April 2024 it is a day-one right — no qualifying period of service is needed.
- How long do I have to respond to a flexible working request?
- You must give a final decision, including any appeal, within two months of receiving the request, unless you and the employee agree a longer period in writing. Use our deadline calculator to work out the exact date.
- How many flexible working requests can an employee make?
- Up to two statutory requests in any 12-month period.
- Can I refuse a flexible working request?
- Yes, but only for one or more of the eight statutory business reasons, and you should consult the employee first. You should explain the reason for the decision.
- Do I have to consult the employee before refusing?
- Yes — before refusing, you should consult the employee to discuss the request and consider possible alternatives, in line with the statutory procedure and the Acas Code.
- Is an approved flexible working change permanent?
- Usually yes — an agreed request is normally a permanent change to the employee's contract, unless you agree otherwise or agree a trial period.
- Can an employee appeal if I refuse?
- There's no separate statutory appeal stage, but offering an appeal is good practice under the Acas Code, and any appeal must still fit within the overall two-month decision period (unless extended by agreement).
- What's the difference between flexible working and a reasonable adjustment?
- A flexible working request is a general statutory right for any employee. A reasonable adjustment is a stronger, separate duty owed to a disabled employee under the Equality Act 2010 — if a change is needed because of a disability, treat it as a reasonable adjustment, not just a flexible working request.
- Can refusing flexible working be discrimination?
- It can. Even where the flexible working procedure is followed, a refusal that puts a group sharing a protected characteristic at a disadvantage (for example indirect sex discrimination in relation to childcare) can be challenged under the Equality Act 2010 (see British Airways plc v Starmer). Consider this before refusing.
