The United Kingdom has legislated to make it harder for employers to turn down flexible working requests, with the main change planned for autumn 2027. This article sets out what the government has said so far, what is still undecided, and how any team can build a fair, productive way of handling requests.
What is changing in UK flexible working law?
Flexible working means any arrangement that changes when, where or how much someone works, such as compressed hours, staggered start times, part-time schedules or working from home on set days. Under current UK rules, the government’s guidance says all employees have the legal right to request flexible working, and requests can be made from the first day in a job. An employer can refuse an application if they have a good business reason for doing so.
The Employment Rights Act 2025 tightens the refusal side. According to the UK government’s response to its consultation on improving access to flexible working (updated on September 15, 2026), employers will be required to reject a request only where it is reasonable to do so. They will also have to set out the basis for the decision by referring to the relevant statutory business grounds, which are the reasons already listed in law. The government’s separate timeline for implementing the Act lists flexible working among the measures that will take effect in October 2027, and it notes that dates depend on parliamentary processes and could shift.
What must employers do before saying no?
The government has also confirmed a process that employers will have to follow before they reject a request. According to the consultation response:
- The employer must hold a meeting before rejecting a request, aimed at considering feasibility and exploring suitable alternatives, “with a view to reaching an agreement with the employee.”
- The meeting must take place within the existing two-month decision period, and the employer must give fair and reasonable notice. No fixed notice period was set.
- The employee must be told the purpose of the meeting in advance.
- The employer must give written notice of the meeting outcome and the final decision.
The response also records what was left out. A requirement for the decision-maker to attend was dropped from the legislation, and the Act does not add a statutory right to appeal or to be accompanied. The government said the Advisory, Conciliation and Arbitration Service (Acas), the UK body that publishes workplace codes of practice, will issue a draft updated code for public consultation, and that the changes are intended to take effect together in autumn 2027.
These details are dated. They come from government publications available as of November 2026 and may change before the rules take effect.
Does this matter if your team is not in the UK?
Legal duties apply only where the law applies, and this article is not a guide to anyone’s legal obligations. The wider lesson travels well, though. Many teams now employ people across several countries, and an informal approach to requests, where outcomes depend on which manager is asked, creates inconsistency whatever the local law says.
A consistent, written process helps in three ways. It reduces the time managers spend improvising each case. It gives employees a predictable path, which supports trust. And it forces the real constraints of a role into the open, so that a refusal rests on a business reason that can be explained rather than on habit.
How should a team judge whether a request is workable?
The legal phrase “reasonable” is a useful discipline even outside the law. A manager can ask a short series of questions before answering.
What does the work actually require?
Separate the outcomes of a role from the habits around it. If a customer needs a reply within one hour between 9 a.m. and 5 p.m., that is a requirement. If the team simply has always met at 9 a.m., that is a habit. Requirements limit flexibility; habits can usually be negotiated.
Can the coverage be met another way?
Many requests can be met with a rota, a handover note or a shared inbox. The question is whether the service level survives, not whether everyone is present at the same moment. A well-kept task system, as described in a simple system for managing tasks, makes coverage visible so that gaps are easy to spot.
What would a trial look like?
A fixed trial, with a review date and agreed measures, turns a yes-or-no argument into an experiment. It lowers the risk for both sides: the employee can show the arrangement works, and the employer can stop it if it does not.
What does a fair process look like in practice?
A short written procedure is enough for most small organizations. A workable outline:
| Step | What happens | Who owns it |
|---|---|---|
| 1. Request | Employee describes the change, start date and duration | Employee |
| 2. Acknowledge | Manager confirms receipt and sets a meeting date | Manager |
| 3. Discuss | Meeting to explore feasibility and alternatives | Both |
| 4. Decide | Written decision with the business reason, if refusing | Manager |
| 5. Review | Trial or arrangement reviewed against agreed measures | Both |
The structure mirrors the UK process described above, without depending on any one country’s rules. Where an organization operates under specific legal duties, it should check those duties with a qualified adviser.
How can you measure whether flexibility is working?
Flexibility is easy to argue about and hard to judge by impression. Agree the measures before the trial begins, and keep them modest. Examples include response times to customers, projects delivered on schedule, the number of handover errors, and team members’ own reports of whether they can focus.
A worked example shows how this might look. Imagine a six-person support team that agrees a four-week trial in which two people shift their hours to start and finish one hour later. Before the trial, customer replies average 3 hours. During the trial the team tracks the same figure. If replies average 2.8 hours, the arrangement has not harmed the service; the change is 0.2 hours, or about 7 percent faster (0.2 divided by 3). If replies rise to 4 hours, the increase is 1 hour, or about 33 percent, and the team has clear evidence for adjusting the rota. The figures are invented for illustration, but the logic holds: compare the same measure before and during.
For the broader question of how output relates to hours, see what output per hour tells your team. For evidence on how people divide their working days between home and a workplace, see what time-use data says about working from home.
What should managers avoid when handling requests?
A few habits quietly undermine good processes:
- Judging by visibility. Treating presence as proof of effort rewards people who are seen, not people who deliver.
- Deciding case by case without records. Without notes, similar requests receive different answers, and fairness is impossible to demonstrate.
- Hiding behind vague reasons. “It will not work for the business” is not a reason; a named constraint, such as live phone coverage until 6 p.m., is.
- Letting flexibility swallow collaboration. Where people work different hours, meetings need discipline. The advice in how to run meetings that respect time applies even more strongly when schedules differ.
- Ignoring requests until the deadline. Under the UK’s current rules, employers must decide within two months, so waiting is itself a decision.
Preparing now rather than in autumn 2027
The UK reforms are a reminder that flexible working is moving from a favor to a managed process. The government has confirmed a reasonableness test, a pre-refusal meeting and written outcomes, with the intended start in autumn 2027, though the dates may move and Acas guidance is still to come. Teams that write down their coverage requirements, adopt a short request procedure and agree simple measures for trials will be ready for the rules and, more importantly, will make better decisions about how work gets done.
