The Small Business Guide to Flexible Working Requests

Flexible working has shifted from "nice-to-have perk" to "deal-breaker absence." Your best candidates now expect the ability to work from home some days, adjust their hours, or compress their week. In many jurisdictions—including the UK under the Employment Relations (Flexible Working) Act 2023—they have the legal right to ask. And that means you, as a small business owner, need a fair, documented process to handle these requests without paralysing operations or inviting legal trouble.

This guide walks you through what flexible working is, what the law requires, how to assess requests fairly, and what actually works in practice for teams under 50 people.

What counts as flexible working?

Flexible working is any working pattern that departs from your standard 9-to-5, five-days-a-week model. Here's what employees typically ask for:

Remote or hybrid working — working from home some or all of the week. Common variants are three days office, two days home; or fully remote. Flexible hours (flexitime) — choosing start and finish times, often around a core window (e.g., core hours 10am–3pm, but you can start anywhere from 7am–10am). Compressed hours — fitting 40 hours into four days instead of five (e.g., four 10-hour days). Part-time working — reducing hours or days worked. Job sharing — two people splitting one full-time role. Staggered hours — different start/finish times than teammates. Annualised hours — a set number of hours across the year, with flexibility in when you work them. Term-time working — working only during school terms (common for parents).

Most requests are either remote/hybrid or a shift in hours. Both are manageable once you have a process.

The legal framework: what you must do

In the UK, every employee has the right to request flexible working from day one of employment. (It wasn't always day-one—it used to kick in after 26 weeks. That changed in April 2024.) You'll find the statutory framework at gov.uk/flexible-working and Acas has published a statutory Code of Practice on Flexible Working Requests that you should read once (really—it's shorter than it sounds).

Here's the skeleton:

The employee submits a written request saying what they want, when they want it to start, and what effect they think it'll have on the business. You must consider it genuinely. Not rubber-stamp, not dismiss—actually think it through. You respond within two to three months with approval, conditional approval, or refusal. You can only refuse on specific business grounds. The employee can appeal a refusal.

The right is to request, not to demand. You're not obliged to say yes. But you are obliged to consider it properly.

Grounds for refusal

You can refuse a flexible working request, but only if you have a genuine business reason. The law specifies these grounds:

• Additional cost burden — the arrangement would create genuine extra costs (e.g., hiring agency staff to cover a shift, new equipment)
• Inability to meet customer demand — you can't deliver service with the proposed hours
• Inability to reorganise work among existing staff — you've genuinely explored it and it won't work
• Inability to recruit additional staff — you've tried and there's no one to hire
• Detrimental effect on quality or performance — the work would measurably suffer
• Insufficient work during proposed hours — if someone wants to work 6am–10am, but your customers aren't awake until 9am, that's a problem
• Planned structural changes — you're reorganising anyway

These must be specific to the request, not generic. "We're retail and need people in the shop" is too broad. "We're retail, this request is for full remote, 60% of revenue is direct customer interaction, this arrangement won't work because [detail]" is specific. And it's documented.

How to handle a request: the step-by-step process

Step 1: Acknowledge in writing. The moment you receive a request, confirm receipt. Say what they've asked for, confirm the process, and give them a date by which you'll respond. Transparency reduces anxiety and legal risk.

Step 2: Assess the operational reality. Think hard:

• Can the work actually be done under this arrangement?
• Does it create coverage gaps (e.g., no one in the office 9am–1pm)?
• Does it conflict with team collaboration, client-facing work, or supervision?
• Will it cost money? If so, how much?
• Are you treating this person fairly compared to others in similar roles?

If you're unsure, propose a trial period—three to six months. Both parties get real data instead of guesses.

Step 3: Meet with the employee. Sit down and discuss:

• Why they want the change
• The exact logistics (which days? which hours? communication?)
• Your concerns (and whether they're solvable)
• Compromises (maybe three days remote instead of four)

The employee may have the right to bring someone with them. Check your local rules.

Step 4: Decide and document. Approve, approve with conditions, or refuse—and put it in writing.

If approving:

• Confirm exact hours/days, start date, permanent or trial, any conditions (e.g., must attend fortnightly in-person meetings), review date
• Treat this as a contract variation—update employment contracts or issue a variation letter
• Update payroll to reflect changes in hours, pay, or pattern
• Inform the team (with the employee's permission)

If refusing:

• Explain which business ground(s) apply
• Give specific details of why this request triggers that ground
• Tell them they can appeal
• Put it in writing

Step 5: Implement and review. Schedule a three- to six-month check-in. Is it working? Unforeseen problems? Does anything need adjustment?

Practical things that often go wrong

Time tracking for flexible workers

When people work variable hours, you need accurate time records. This is a compliance issue (working time regulations, rest breaks, maximum hours) and a fairness issue (you can't calculate overtime or holiday without it). Use a time recording system that handles flexible patterns, or integrate time tracking into your HR software.

Pay and benefits implications

If someone moves from five days to four, their salary is pro-rated. If they go from full-time to part-time, same. But check your pension scheme and other benefits—some have "full-time only" thresholds. Know the rules before you approve. When it changes, update payroll and employee benefits.

Home working: equipment, insurance, security

If the employee works from home:

• Do they have a suitable workspace and equipment? (You may need to provide a laptop, monitor, or allowance.)
• Does your data security policy cover home working? (VPN? Encryption? Screen privacy?)
• Have you checked your insurance? (And do they need to check theirs?)
• Are you compliant with working-from-home legislation? (Fire safety, DSE regulations, etc.)

These details matter. A home worker without decent kit, VPN access, or thought to desk setup will be less productive—and you're liable if something goes wrong.

Team dynamics and fairness

A flexible arrangement must not unfairly burden the rest of the team. If one person works from home every Friday, but colleagues must cover their desk, resentment builds. Design arrangements that genuinely work for the team, not just the individual. Sometimes that means proposing a compromise or saying no.

Keeping contracts and systems in sync

This happens all the time: you agree to flexibility, but the contract still says "standard hours" and payroll processes them as full-time. Then confusion erupts in month three. Update the contract. Update payroll. Update leave-tracking. Everything aligned.

Common mistakes that undermine fairness

Refusing without genuine thought. Even if you're inclined to say no, you must actually consider it. An employee who feels dismissed will disengage or leave—and may have grounds for a tribunal claim.

Inconsistent decisions. Approving flexibility for one employee and refusing a similar request from another (with no documented business reason for the difference) is discrimination. Document your reasoning.

Not reviewing. An arrangement that isn't reviewed can drift into problems. Schedule a review and conduct it.

Forgetting the appeal process. If you refuse, the employee can appeal. Have a process for that appeal (usually a second manager or informal discussion). If you don't, you're vulnerable.

Why flexibility actually helps small businesses

Flexible working is not just an employee perk. It's good for your bottom line:

Retention. People who can work flexibly stay longer. Turnover is expensive.

Recruitment. Offering flexibility widens your talent pool—especially in tight labour markets. You're no longer competing only with local candidates; you can attract remote talent.

Productivity. Many people report being more productive when they have control over how they work. Fewer commuting hours. Fewer office interruptions. Better focus.

Cost. Hybrid working can reduce office space needs.

Resilience. A team used to flexible working adapts faster to disruption (illness, weather, supply hiccups). They've already practiced distributed work.

For small businesses, flexibility is often easier than for large corporations. You have fewer layers, faster decision-making, the ability to tailor arrangements to individuals. That's your competitive edge. Use it.

Frequently Asked Questions

Q: Can an employee request flexible working multiple times? A: Generally yes, but not constantly. The law typically allows one request per 12 months. If they requested four days a week in January and you approved it, they can't request three days in March. But in 12 months, they can request again.

Q: What if the request would cost too much? A: "Additional cost" is a valid refusal ground, but only if genuine. You need to show actual costs, not hypothetical. If approving means you must hire agency staff, that's a cost. If it's just rescheduling, that's not.

Q: Can I approve a request "on trial"? A: Yes. A three- or six-month trial period is sensible. Put conditions in writing and agree a review date. If it's not working, you can revert (after reasonable notice).

Q: Do I have to let them appeal a refusal? A: Yes. The employee has the right to appeal. Have a process—typically a discussion with another manager or formal hearing. Not having an appeal process weakens your position legally.

Q: What if they request flexibility and then stop doing the work? A: That's a performance issue, not a flexible working issue. Handle it through normal performance management—meetings, documentation, improvement plans. Don't use flexibility as a cover for "I don't like their output."

Q: Can I take flexibility back after I've approved it? A: Only for a good reason and with proper notice. If business context genuinely changes (e.g., you've lost a big customer), you can propose reverting. But it requires notice and discussion, not unilateral withdrawal.

Q: What about flexible working and holiday entitlement? A: Holiday entitlement doesn't change, but how you administer it may. If someone works compressed hours (four 10-hour days), holiday is still measured in days, not hours. If they work annualised hours, holiday is deducted from the annual total. For detailed guidance, check UK statutory leave entitlements and document how you'll calculate it when you approve.

Q: Do I need a formal flexible working policy? A: You don't strictly need one, but it's wise. A one-page document explaining your process, refusal grounds, and appeal procedure means everyone knows where they stand. It also protects you: you can point to a clear, documented process rather than appearing arbitrary.

Flexible working requests are normal now. Handle them like anything important: document the process, consider each request properly, communicate clearly, and update your systems. A fair, transparent approach to flexibility makes your business more attractive to good people, easier to manage, and harder to sue. Start now: if you don't have a written flexible working request process, write one. One page covers the steps above, and you're done.
