How to Request Flexible Working Arrangements

All UK employees can request flexible working from their first day at work — and employers must consider it properly, even if they ultimately say no. This guide walks you through the statutory process, how to build a strong case, what happens if you're refused, and why flexibility matters for both your wallet and your wellbeing.

What Is Flexible Working and Why You Have the Right to It

Flexible working is any arrangement that differs from the standard office schedule or location. That might be remote work, flextime (choosing start/finish times), compressed weeks (four 10-hour days instead of five), job-sharing, or annualised hours.

Since April 2023, the law in the UK changed significantly. You now have the right to request flexible working from day one of employment, not after 26 weeks. Your employer isn't obliged to say yes — but they are obliged to consider your request properly, hold a meeting with you, and explain their reasoning if they refuse.

This matters financially too. The Real Cost of Commuting isn't just money — it's time. Working from home two days a week could save you £2,000–£3,000 a year in transport costs, and that's before you factor in the time reclaimed. For many people, flexible arrangements are worth more than a pay rise.

Your Legal Right Under UK Law

The legal framework is in the Flexible Working (Amendment) Regulations 2023. Here's what you need to know:

Who can request: Any employee in England, Scotland, or Wales. That includes full-time, part-time, and fixed-term contract workers. Agency workers and the self-employed aren't covered.

When: From day one. No waiting period. Some employers may have a cooling-off period (you can request again after 12 months if your first request was refused, or three months if it was approved), but that comes after your first request is granted or refused.

What counts as flexible: Remote work, part-time, flexible hours, job-sharing, annualised hours, staggered hours, or any other non-standard arrangement you and your employer agree on.

What the employer must do: Acknowledge your request within two weeks, meet with you to discuss within 30 days, make a decision, and explain the business reasons if they refuse. Refusing because "it's not traditional" or "other people will want it too" isn't good enough — they need a legitimate operational reason.

Step-by-Step: How to Make a Flexible Working Request

1. Check your contract and handbook

Before you request, check your employment contract and staff handbook. Some organisations already offer flexible working; you might not need a formal request. If the handbook says "just ask your manager," that's not the statutory process — go formal anyway for protection.

2. Write a formal request

Send a written request (email is fine) to your manager or HR, or the person specified in your handbook. Include:

Your name and position
The date of the request
The flexible arrangement you're proposing (be specific — "remote Wednesdays and Thursdays" not "flexible")
When you'd like it to start
How it would work operationally (this is crucial — see section below)
That this is a statutory request under the Flexible Working Regulations

Make it professional but not stiff. This isn't a legal document — it's a conversation starter.

3. Employer acknowledges within 2 weeks

Your employer should acknowledge receipt and confirm they've received a formal request. If they don't, chase it in writing.

4. Meeting within 30 days

The employer must offer you a meeting to discuss. Attend it prepared to explain:

Why you're requesting this
How it works operationally
How your work will get done
How your team will be covered

You can ask to bring a colleague or trade union rep for support.

5. Decision and written response

Within 30 days of your meeting, the employer must give you a written decision. If approved, they'll confirm the new arrangement and start date. If refused, they must explain the business reason (see below for what counts).

If there's a delay (they need more time to investigate), they can extend to 30 days total. They can't just ignore you.

What to Include in Your Request Letter: Building Your Case

This is where your case lives or dies. A weak request — "I'd like to work from home because it's nicer" — is easy to refuse. A strong one is hard to argue with.

Be specific about the arrangement:

Not: "flexible hours"
Yes: "Monday to Wednesday in office, Thursday and Friday remote, core hours 10am–3pm to overlap with team"

Explain the business benefit:

Better concentration for deep work (if applicable)
No commute means you start earlier or finish later
Reduced distractions for client calls
Better availability for your timezone or distributed team

Show you've thought about the logistics:

How you'll stay connected to the team
How meetings will work
How urgent queries get answered
How you'll handle collaboration needs

Acknowledge potential concerns:

"I know client-facing work needs office presence — I can do that Tuesdays and Thursdays"
"I'll ensure all my work is documented so the team can access it anytime"
"I can flex my hours if there's a project deadline"

If you're negotiating salary or other benefits, this is the moment. How to Negotiate Salary for a New Job covers this in detail, but the principle is the same: flexibility is valuable to you, so it's worth trading for if the employer won't approve the request itself.

Your Employer's Obligations and Timeline

Employers can refuse, but they must have a legitimate reason. The law lists these as acceptable grounds:

Cost — the arrangement genuinely costs the business more
Inability to meet customer demand — clients need you on-site or synchronously
Insufficient work during proposed hours — part-time reduces actual deliverables
Inability to reorganise work among staff — the team can't cover your absence
Detrimental impact on quality or performance — proven with evidence, not assumptions
Existing flexible working arrangements — they're already overloaded with part-timers
Inability to recruit or train — you're the only person who can do the training

What does NOT count:

"It's against company culture"
"Other people might ask next"
"We like to see your face"
"It'll be difficult to manage"

The bar for "difficulty" is high. Managers get upset about change all the time — that's not a business reason.

The timeline is strict. If your employer misses the 30-day meeting deadline or the decision deadline, you have grounds to escalate (and potentially claim that the refusal was unreasonable).

What Happens If Your Request Is Refused

If your employer refuses with a written reason, you have options:

Option 1: Appeal Ask for a meeting to discuss the decision. Sometimes a second conversation reveals they misunderstood your proposal. Many refusals get overturned at appeal.

Option 2: Propose a compromise "I understand client calls are Tuesdays–Thursdays. Can I work remote Mondays, Wednesdays, and Fridays?" A refusal of your ideal arrangement doesn't mean your employer hates flexibility — it might just mean your first proposal didn't fit.

Option 3: Accept and re-request later If you were refused, you can request again after 12 months (or 3 months if it was approved). Things change — your role evolves, the team expands, remote tools improve.

Option 4: Escalate to ACAS or legal advice If your employer:

Refused without a legitimate business reason
Didn't follow the process (didn't meet the deadline, didn't hold a meeting, gave no written response)
You believe discriminated against you (disability, gender, caregiving responsibilities)

Then you have a claim. ACAS (the Advisory, Conciliation and Arbitration Service) offers free advice. If it's discrimination — a man's request approved but a woman's refused, for example — employment tribunals take it very seriously.

Option 5: Accept the refusal and move on If the employer has a genuine business reason and followed the process, the decision stands. But this information is valuable: if flexibility matters to you, consider whether this employer is right long-term.

How Flexible Working Affects Your Pay and Finances

Flexible working doesn't directly change your salary — you get paid for the hours you're contracted for, not the location. But it has real financial knock-ons:

Commuting savings: The Real Cost of Commuting shows the full picture. Two days remote saves most people £1,500–£3,000/year in travel, fuel, parking, and lunch costs. That's a net pay rise without a gross pay rise.

Childcare and elder care: Flexibility often reduces childcare hours needed. A day at home with nursery pickup at 4pm instead of 6pm might save £100–£200/month. That's £1,200–£2,400/year of your take-home.

Tax efficiency: Some flexible arrangements (working from home, allowances for home office wear and tear) have modest tax relief. HMRC allows £6/week flat rate for homeworking costs. Not huge, but real if you're working remote most days.

Job market advantage: If you move roles, flexible working is often a negotiable benefit. You might accept slightly lower pay for better terms — or use your experience to ask for higher pay at a more flexible employer.

For a concrete example: imagine you're on £40,000 salary after tax. Remote work saves you £2,500/year in commuting. That's equivalent to a £3,125 gross pay rise (after 20% tax and 8% NI). So flexible working is genuinely worth thousands.

Frequently Asked Questions

Can my employer ask me to come in on a specific day even if I work remote the other four days?

Yes. Your flexible arrangement is a contract between you and them — if it says "flexible hours, core presence Tuesdays," then Tuesdays are mandatory. If they change their minds and want you in every day again after you've agreed a flexible arrangement, that's a contract change and they need your agreement (or proper notice and revised contract). Document what you agree to in writing.

What if my manager says "yes" but then keeps asking me to come in?"

That's a breach of the arrangement. Document each request (emails are proof) and raise it formally with HR. Your manager's informal approval doesn't override the formal agreement — if they want to change it, they need to go through the process again.

Do I have to mention this in my original job application?

No. You can request after you start. Many people ask at interview to see the organisation's attitude, but you don't have to. The legal right comes after you're employed.

Can they refuse because I'm on probation?

The law doesn't exempt probation periods. Technically you can request from day one. Practically, most employers will say "let's revisit in three months once you've settled in." That's reasonable, but they still have to consider the request properly, not just dismiss it because you're new.

What if I'm already working flexible hours unofficially?

Formalise it. Write an email to your manager: "I wanted to confirm in writing that I'm currently working [describe arrangement]. I'd like to make this formal under the Flexible Working Regulations." This protects you if the arrangement is withdrawn or disputed.

Does flexible working affect my eligibility for redundancy, pension, or other benefits?

Generally no. Your employment terms don't change — you're still entitled to the same pension, maternity pay, redundancy rights, etc. Check your specific scheme, but most don't penalise flexible workers.

Can I request full-time remote work if the job advert said "office-based"?

Yes, you can request it. The job advert isn't binding — it's the contract and role that matter. But your employer can refuse if they have a legitimate business reason. For example, "This is a client-facing role requiring daily office presence" is a valid reason. "We want to build company culture" isn't.

If I'm refused, do I have to tell the employer I'm thinking about leaving?

No. But if flexibility is a dealbreaker for you, it's worth being honest: "I appreciate your position, but I need to explore other options." This sometimes prompts a second conversation or alternative proposal.

What if my employer doesn't have a formal policy on flexible working?

Doesn't matter. The statutory right exists regardless of whether they've written a policy. A formal request triggers the legal obligation to consider it properly. Their lack of a policy isn't a defence.

Can I request flexible working if I'm union-represented?

Yes — and absolutely involve your union rep in the process. Unions often have expertise in flexible working cases and can provide support in meetings and appeals.
