Flexible working can mean starting earlier, compressing weekly hours, working from home or sharing a role. UK employees have a legal process for requesting changes, and employers have duties when deciding what is workable. Understanding that distinction helps both sides avoid a rushed refusal or unrealistic expectations of automatic approval.
These rules concern employees in England, Scotland and Wales. Northern Ireland has a different statutory framework.
Who can request flexible working?
Employees can make a statutory flexible working request from their first day of employment. They do not need to be a parent, carer or disabled, and they do not have to explain a personal reason. Employment status matters: someone legally classed as a worker rather than an employee may not qualify for the statutory procedure, although they can ask informally.
An employee can make two statutory requests in any 12-month period, but only one live request with the same employer at a time. A request remains live while a decision or appeal is pending, including an agreed extension.
Changes might involve part-time work, flexible hours, compressed hours, job-sharing, altered start times or home and hybrid working. The law gives a right to request flexibility, not an unconditional right to receive it.
How to make a valid flexible working request
A statutory request must be in writing, usually by email or letter. Check the employer’s flexible working policy for any designated form or recipient. Include the date, a statement that this is a statutory request, the proposed changes to hours, times or location, when they should begin, and whether and when you made an earlier statutory request.
Employees no longer have to explain how the change might affect the business. Nonetheless, a practical proposal can help. For example, specify which office days you could attend rather than asking vaguely for “more hybrid working”. Keep a copy of correspondence to establish the timeline if a dispute arises.
What employers must do after receiving a request
Employers must handle applications reasonably, assess the impact and consult the employee before refusing the request or offering less than full acceptance. Consultation should be a genuine discussion, not a meeting arranged after the decision.
A final decision, including any appeal, normally must be made within two months of the request. The parties can agree an extension. Employers should communicate the outcome clearly and explain refusal using a permitted business reason.
When a request is accepted, the agreed contractual change and its start date should be confirmed in writing. Contract particulars should be updated promptly, no later than 28 days after approval. For a temporary trial, record its duration and review arrangements.
Which reasons allow an employer to refuse?
An employer cannot reject a statutory request simply because a manager dislikes flexible working. Refusal must be based on at least one of eight recognised business reasons:
Additional costs; inability to reorganise work among existing staff; inability to recruit additional staff; detrimental effects on quality; detrimental effects on performance; detrimental effects on meeting customer demand; insufficient work during the proposed periods; or planned structural changes.
These reasons should connect to the actual role. A customer-support team might demonstrate that a proposed timetable leaves a crucial telephone shift uncovered. A blanket assumption that remote staff perform poorly, however, is not a substitute for individual consideration.
Good practice includes examining evidence, discussing alternatives and recording the reasoning. Different hours, fewer homeworking days or a trial might address the concern.
Hybrid working rights: a practical example
There is no general legal entitlement to work from home for a particular number of days. A hybrid arrangement can be requested, but an employer may identify legitimate operational constraints. An office-attendance policy does not remove the right to make an individual request.
Imagine an accounts administrator requesting homeworking on Mondays and Fridays to reduce a difficult commute. Their manager worries about Friday invoice approvals. Instead of immediately refusing, they could explore a Thursday office handover, secure remote access and a six-week trial measured against invoice turnaround times. That tests the concern rather than treating an assumption as fact.
Employees can strengthen the conversation by explaining their proposed schedule, urgent-work coverage and duties requiring onsite attendance.
When other workplace rights also matter
A request connected to disability may trigger a separate duty to make reasonable adjustments under equality law. Simply processing and refusing a statutory flexible working application does not discharge that duty. Adjusted hours or homeworking may, depending on the circumstances, be a reasonable adjustment.
Refusals can also raise discrimination questions, including where a workplace rule disproportionately affects employees with childcare responsibilities without adequate justification. Employees are protected against dismissal or other detrimental treatment for making a statutory request.
Our related guides to reasonable adjustments at work, family leave rights and changing employment contracts explore how these protections fit together.
What to do if your request is refused
Ask which business reason applies and what facts support it. Consider proposing a narrower timetable, temporary trial or revised hybrid pattern. Check the internal appeals procedure: there is no automatic statutory right to appeal, but the Acas Code encourages employers to offer one.
An employment tribunal can consider procedural failures, refusal based on incorrect facts or other unlawful treatment. It will not simply overturn a properly handled decision because an employee prefers another arrangement. Employees normally must notify Acas for early conciliation before claiming.
For most tribunal claims about events on or after 1 October 2026, the deadline is six months minus one day. Earlier events generally remain subject to the previous, shorter limit. The starting date and any early-conciliation pause matter, so seek advice promptly; an internal appeal does not automatically stop the clock.
Are further changes coming?
The Employment Rights Act 2025 provides for stronger refusal rules, including explaining why rejection is reasonable and following specified consultation steps. As of October 2026, these reforms are expected in autumn 2027 and are not yet the operative test. The existing Acas Code continues to apply meanwhile.
Conclusion
Flexible working works best when employees make precise requests and employers assess genuine operational needs rather than relying on blanket policies. Current law supports meaningful discussion, timely decisions and clear reasons for refusal. Recognising overlapping disability, discrimination and contractual rights makes that process fairer.
Frequently asked questions
Can my employer refuse flexible hours?
Yes, but a statutory request can be refused only for a recognised business reason, after appropriate consultation and reasonable handling. Preference for traditional hours is not itself one of those reasons.
Do I need six months’ service before applying?
No. In England, Scotland and Wales, employees can make a statutory request from their first day. Northern Ireland follows different rules.
Can I request two days of homeworking each week?
Yes. You can request a hybrid pattern, but those days are not automatically guaranteed. Your employer must consider the application through the statutory process.
Does an unsuccessful request change my contract?
No. Existing contractual arrangements ordinarily continue after refusal. Any agreed change should be documented, including its start date and whether it is permanent or temporary.
