Flexible working is no longer a perk you beg for — in the UK, it’s a right you can request from day one of employment. Yet many employees never ask, held back by fear of looking uncommitted or simply not knowing how to frame the conversation. The difference between requests that succeed and requests that fail usually isn’t the merits of the case — it’s the preparation. Here’s how to ask for flexible working at your current job in a way that makes “yes” the easy answer.
Know Your Legal Position First
Since April 2024, UK employees have had the right to request flexible working from their first day — no 26-week wait. You can make two statutory requests per year, and employers must respond within two months, consulting with you before refusing. They can only refuse for specific business reasons, such as the burden of additional costs or inability to reorganise work among existing staff. This is a meaningful right, not a token gesture.
Flexible working covers far more than working from home: flexitime, compressed hours, job-sharing, part-time, staggered hours, term-time working, and hybrid arrangements all qualify. Think broadly about what would actually improve your life — sometimes a 9:30 start (to do the school run) matters more than remote days. The Acas guidance on flexible working requests sets out the process clearly, and GOV.UK explains your statutory rights in plain terms. Read both before you act.
Build Your Business Case
The golden rule: frame your request around outcomes, not desires. “I’d like to work from home on Fridays” is a wish; “Working from home on Fridays would let me cover the quiet deep-work tasks without office interruptions — my output on project X rose 20% during the weeks I trialled this” is a business case. Gather evidence: your performance data, examples of successful remote work during the pandemic, and how you’ll handle the practicalities (meetings, collaboration, availability).
Anticipate objections and answer them before they’re raised. Worried about team cover? Propose a rota. Worried about client meetings? Commit to being in for them. Worried about junior staff supervision? Suggest structured check-ins. A request that arrives with solutions attached is dramatically harder to refuse than one that just states a preference. If possible, propose a trial period — “let’s try it for three months and review” — which lowers the perceived risk for your manager to near zero.
Have the Conversation Skilfully
Start informally before going formal. A conversation with your manager — “I’d like to explore some flexibility in my working pattern; can we discuss what might work?” — lets you gauge the temperature and shape the proposal collaboratively. Managers who feel consulted become allies; managers who receive a formal letter out of the blue become defensive. The informal chat is where you learn what matters to them, so your formal request can address it.
When you make the statutory request, put it in writing (email is fine), state clearly that it’s a statutory flexible working request, describe the change you want, explain the effect you think it will have on the business and how you’ll mitigate it, and give your proposed start date. Keep the tone positive and professional throughout — you’re proposing an improvement, not lodging a complaint. Looking professional while working from home also helps: visible professionalism reassures managers that flexibility won’t mean slacking.
What if your manager says no informally?
Don’t treat an informal no as final — the statutory process exists precisely for this. Make the formal request anyway; it triggers proper consideration and a written decision with reasons. If the refusal seems unreasonable, you can appeal internally, raise a grievance, or seek advice from Acas. An unreasonable refusal can potentially support an employment tribunal claim.
Make It Work Once Approved
Getting approval is the start, not the end. The first three months set the pattern: be visibly reliable, over-communicate initially, hit every deadline, and make your flexibility invisible to everyone except you. The colleagues who make flexible working look effortless are the ones who put in the effort to make it so — at least at first.
Protect the arrangement by reviewing it proactively. Suggest a check-in after the trial period with your own assessment of how it’s going, backed by evidence. This demonstrates maturity and gives your manager confidence — which matters if you ever want to extend or adjust the arrangement. And be a good citizen: flexibility that visibly burdens colleagues breeds resentment and risks reversal. Setting up decent video call equipment is a small investment that pays off enormously in how professional your remote presence feels.
Flexible Working for Parents and Carers
Parents and carers are among flexible working’s biggest beneficiaries — and the law recognises it. Beyond the general right to request, parents have specific rights: unpaid parental leave (18 weeks per child, usable flexibly), the right to time off for dependants in emergencies, and since 2024, a day-one right to request flexible working that many parents use for school-run-friendly hours or term-time arrangements. Carers have parallel protections, including the right to carer’s leave. When making your request, you’re not asking for a favour — you’re using rights Parliament created precisely for your situation. Frame it that way, confidently and without apology. Employers who’ve handled parental requests well in the past are your allies; ask colleagues how theirs went. And remember that GOV.UK’s guidance for parents sets out the full picture — many employees don’t realise how much support the law actually provides.
Frequently Asked Questions
Can I request flexible working during probation?
Yes — the right applies from day one, including during probation. In practice, many people wait until they’ve established themselves, but legally there’s no barrier. If flexibility was a condition of accepting the role, raise it during hiring, not after.
What counts as a valid reason for refusal?
The law lists specific grounds: burden of additional costs, detrimental effect on ability to meet customer demand, inability to reorganise work, inability to recruit additional staff, detrimental impact on quality or performance, insufficiency of work during proposed periods, and planned structural changes. Vague “it wouldn’t work” isn’t enough.
Can I request flexible working more than once?
You can make two statutory requests in any 12-month period. If your first request is refused, you can refine and resubmit — many successful arrangements come from a second, better-evidenced request that addresses the reasons for the first refusal.
Does flexible working affect my pay or promotion chances?
It shouldn’t — less favourable treatment because of a flexible working request can be unlawful. In practice, stay visible: keep delivering excellent work, maintain relationships, and don’t let physical absence become professional absence.
The Bottom Line
Asking for flexible working at your current job is a straightforward process with the law on your side — the right exists from day one, the procedure is simple, and employers must consider requests properly. Success comes from preparation: know your rights, build a business case with evidence, start with an informal conversation, make a clear written request, and then make the arrangement work so well nobody questions it. The worst outcome of asking is a no you can appeal; the best outcome is a working life that actually fits around the rest of your life. That’s worth an email.
