Flexible working used to feel like a perk reserved for a lucky few. Today it is a normal part of how many UK businesses operate, and it is something your team members can formally ask for. If you employ people, it pays to understand how flexible working requests work, what you can and cannot do when one lands on your desk, and how to handle the conversation in a way that keeps everyone onside.
This guide walks you through the basics in plain English, so you can respond fairly and confidently when a request comes in.
This article is general information only and is not legal advice. Employment rules can change, so always confirm the details that apply to you on GOV.UK or speak to a qualified employment adviser.
What flexible working actually covers
Flexible working is a broad term. It simply means any working pattern that differs from the standard nine-to-five, five-days-a-week setup. An employee might want to change when they work, where they work, or how many hours they work in total.
Common arrangements include:
- Part-time — fewer hours or fewer days than a full-time role.
- Flexitime — choosing start and finish times around a set of core hours.
- Hybrid working — splitting time between home and the workplace.
- Compressed hours — working full-time hours across fewer, longer days.
- Staggered hours — different start, break and finish times from colleagues.
- Job sharing — two people splitting one full-time role between them.
None of these is automatically right or wrong. What works depends on the role, the team and the nature of your business. A request is just the start of a conversation, not a demand you must always say yes to.
The day-one right to request
The right to ask for flexible working has shifted over recent years. The general direction of travel has been to make it easier and quicker for employees to raise a request, including treating it as something they can do early in their employment rather than after a long qualifying period. Because the exact rules and any qualifying conditions can change, always check the current position on GOV.UK before you rely on a particular detail.
The important thing to grasp is the difference between a right to request and a right to receive. Your employees can make a formal request. You are required to deal with it properly and within a reasonable timescale. You are not required to agree to every request, provided you have a sound business reason for any refusal.
How to handle a request fairly
When a request arrives, treat it seriously and consistently. Handling each one in a similar, structured way protects you and reassures your team that decisions are not being made on a whim. A sensible approach looks like this:
- Acknowledge the request promptly and let the employee know you have received it.
- Read it carefully and note exactly what they are asking for and when they want it to start.
- Arrange a conversation to understand the request and explore whether it can work.
- Consider the impact on the role, the wider team and your customers.
- Look at whether a trial period or an adjusted version of the request might work, even if the original cannot.
- Make a decision and confirm it in writing, explaining your reasoning clearly.
Talking it through matters. Often a request that looks tricky on paper becomes workable once you understand what the person is really trying to achieve, whether that is managing childcare, easing a long commute or supporting their health.
Lawful grounds to refuse
You can turn down a request, but you need a genuine business reason rather than a vague reluctance to change. The recognised grounds typically relate to the practical realities of running your business. These commonly include:
- The burden of extra costs the change would create.
- A negative effect on your ability to meet customer demand.
- An inability to reorganise work among existing staff.
- An inability to recruit additional staff to cover the gap.
- A detrimental impact on quality or performance.
- Not enough work during the periods the employee wants to work.
- Planned structural changes to the business.
Whatever your reason, write it down clearly and base it on facts. A decision you can explain calmly is far easier to defend than one that rests on "it just won't work". If you refuse, it is good practice to explain which ground applies and why.
Process and timescales
There is an expected framework for dealing with requests, and keeping to it protects you. In broad terms you should respond within a reasonable period, deal with the request in a reasonable manner, and only refuse for one of the permitted business reasons. The precise time limits and any requirement to consult before refusing can change, so confirm the current expectations on GOV.UK.
It is also worth setting your own internal policy so managers know what to do. Tie this in with your written terms of employment. Our guide on what to include in an employment contract covers how working patterns should be recorded, and if a request is agreed it usually becomes a permanent change to the contract unless you both agree otherwise. For the wider picture, see our overview of workplace rules for small businesses.
The business benefits
It is easy to view flexible working as a cost or a complication. In practice it can be a genuine advantage for a small business. Offering flexibility can help you attract people you might otherwise miss, including experienced workers who cannot commit to rigid hours. It often improves retention, because staff who can fit work around their lives are less likely to leave.
There are knock-on benefits too. A flexible employer can sometimes reduce overheads, widen its recruitment pool beyond the local area, and build a reputation as a good place to work. Flexibility can also interact with other entitlements, so it helps to understand the basics of holiday entitlement and pay when you agree changed hours, since leave is usually calculated in proportion to the days worked.
Flexible working is a conversation, not a tick-box exercise: handle each request fairly and you often gain a happier, more loyal team in return.
Frequently asked questions
Do I have to say yes to a flexible working request?
No. You must consider it properly and respond within a reasonable time, but you can refuse if you have a genuine business reason that falls within the recognised grounds. The key is to base your decision on facts, explain it clearly and apply the same fair process to everyone.
Can an employee ask more than once?
Employees can make requests over time, though there may be limits on how many formal requests can be made within a set period. Circumstances change, so a request you could not accommodate last year might be workable now. Check the current rules on the number and frequency of requests on GOV.UK.
Does agreeing to flexible working change the contract permanently?
Usually, yes. If you accept a request, the new working pattern normally becomes a permanent variation to the employee's terms unless you both agree it is temporary or a trial. It is sensible to confirm the change in writing so there is no confusion later.
