Flexible Working Regulations in the UK: What to Know in 2026

Flexible working isn’t a “nice to have” anymore. For a lot of small businesses in 2026, it’s part of staying competitive, keeping good people, and running a workplace that can adapt quickly when life (or the market) changes.

But flexible working also comes with legal obligations. If you handle requests informally, inconsistently, or without a clear process, you can unintentionally create risk - especially around discrimination, contractual changes, and employee relations.

This guide explains the UK’s flexible working regulations in plain English, from a small business perspective. We’ll cover what the law expects of you, what a “reasonable” process looks like, when you can say no (and how), and how to set your business up to manage flexible working properly from day one.

This article is general information only and isn’t legal advice. Employment law can change, and you should take advice on your specific circumstances.

What Do The Flexible Working Regulations Require In 2026?

In the UK, employees have a legal right to request flexible working. This doesn’t mean they have an automatic right to get flexible working - but it does mean you have to deal with requests lawfully.

As at 2026, the key legal framework is the statutory right to request flexible working under the Employment Rights Act 1996, supported by the Employment Relations (Flexible Working) Act 2023 (in force from 2024) and the Flexible Working Regulations 2014 (as amended).

In practice, the flexible working rules (and related guidance) mean:

• It’s a day-one right. Employees can make a statutory flexible working request from the first day of employment.
• Employees can make up to two statutory requests in a 12-month period.
• You must deal with the request in a “reasonable manner”. This includes consulting with the employee before refusing.
• You must give a decision within two months of receiving the request (unless you agree an extension with the employee).
• You can only refuse for specific business reasons (set out in legislation), and you should be able to explain them clearly.

One thing to keep in mind: employment law can change, and government guidance can shift too. If you’re relying on a policy you wrote years ago, 2026 is a good time to refresh it and make sure it matches how you actually run your business.

What Counts As “Flexible Working”?

Flexible working is a broad category. A request might be for:

• Remote or hybrid work (working from home some or all days)
• Part-time hours
• Compressed hours (same weekly hours across fewer days)
• Flexitime (start/finish time flexibility)
• Job-sharing
• Annualised hours (set annual hours, variable weekly pattern)
• Term-time working

Even if you already offer flexibility informally, statutory requests matter because they trigger a legal process (and time limits) you need to follow.

Who Can Make A Flexible Working Request (And When)?

In 2026, the key point for employers is that eligibility is much broader than it used to be.

An employee can make a statutory flexible working request if:

• they are an employee (not genuinely self-employed), and
• they have not already made two statutory requests in the last 12 months.

Because it’s now a day-one right, you might receive a request during probation, or even shortly after onboarding. That doesn’t mean you have to say yes - but it does mean you should be ready with a consistent process that works even for newer hires.

If your documentation isn’t clear on status or expectations, it’s easy to run into disputes about what role someone has agreed to perform and how. This is one reason it’s worth having a properly drafted Employment Contract in place that sets out core hours, place of work, and how changes are handled.

Do Casual Workers Or Contractors Have The Same Rights?

Not necessarily. The statutory flexible working process applies to employees. If you engage contractors, the arrangement should be handled through the contract you have with them (and you’ll want to be careful that your “contractor” isn’t actually an employee in disguise).

Even where the strict statutory process doesn’t apply, flexible working can still create other risks - like consistency issues, discrimination concerns, and data protection obligations - so it’s still worth managing requests thoughtfully.

How Should Small Businesses Handle Flexible Working Requests In Practice?

When you’re busy running a small business, it’s tempting to deal with flexible working requests via quick chats and informal trial periods. That can work - but you still need to meet the minimum legal requirements, and you need to avoid setting accidental precedents that are hard to reverse later.

A sensible, compliant approach usually looks like this:

1) Put A Clear Process In Writing

You don’t need a 30-page manual. But you do need something your managers can follow consistently, including:

• how requests should be made (e.g. email to a nominated person)
• what information you want included (for example, the change they’re asking for and when they’d like it to start)
• how meetings are arranged
• how decisions are documented and communicated
• how appeals (if offered) work

This is often set out in your Workplace Policy documents and reinforced in your wider onboarding materials.

2) Acknowledge The Request And Calendar The Deadline

The two-month decision deadline matters. Missing it can turn a manageable request into a formal grievance or legal claim risk.

Set a simple internal habit:

• confirm receipt in writing
• book a consultation meeting promptly
• set reminders for decision drafting and sign-off

3) Consult Before You Refuse

In 2026, consultation isn’t optional if you’re going to refuse. You should talk to the employee about:

• why they’re requesting the change
• what they’re proposing in practical terms
• how you think it may affect customers, workflow, supervision, or costs
• whether a modified arrangement could work (e.g. trial period, different days)

This doesn’t need to be confrontational. In many small businesses, a short meeting plus a follow-up email summary is enough - as long as it’s genuine consultation and not a tick-box exercise.

4) Consider Trial Periods (But Document Them)

Trial periods are often the best compromise for small teams where you genuinely don’t know how a change will affect operations until you try it.

If you do a trial, clarify in writing:

• how long it will run
• what “success” looks like (KPIs, response times, coverage requirements)
• how performance and impact will be reviewed
• what happens at the end (confirm, modify, or revert)

Without this, you risk the trial becoming the new normal - and it can be harder to roll back later without triggering contractual disputes.

When Can You Refuse A Flexible Working Request (Legally)?

This is where small business owners often feel stuck. You want to be fair, but you also have rosters to cover, customers to serve, and work that needs supervision.

Under the flexible working rules, you can refuse a statutory request for one (or more) of the recognised business grounds. In plain English, these cover situations where the request would cause real operational difficulty.

The statutory reasons include:

• the burden of additional costs
• detrimental effect on ability to meet customer demand
• inability to reorganise work among existing staff
• inability to recruit additional staff
• detrimental impact on quality
• detrimental impact on performance
• insufficiency of work during the periods the employee proposes to work
• planned structural changes (e.g. restructure, redundancy, new systems)

The key is that your refusal should be evidence-based, not assumption-based.

What Does “Evidence-Based” Look Like For A Small Business?

You don’t need a corporate report. But you should be able to point to practical facts, for example:

• your opening hours and minimum staffing needs
• customer booking/footfall patterns
• supervision requirements for junior roles
• the impact on handover, response times, or safety checks
• why redistribution of work isn’t realistic with your team size

If you say no, put the reasons in writing, link them to the statutory grounds, and keep a record of the consultation and decision-making process.

Common Legal Risks For Employers (And How To Avoid Them)

For most small businesses, the biggest risk isn’t refusing a request. It’s refusing (or agreeing) in a way that creates inconsistency, discrimination risk, or contract confusion.

1) Discrimination And Indirect Discrimination

Flexible working requests often relate to protected characteristics, even when the employee doesn’t explicitly say so. Common examples include:

• sex (childcare responsibilities still disproportionately affect women)
• disability (working from home, altered hours, reduced commuting)
• age (caring responsibilities can affect different age groups)
• religion or belief (specific time requirements)

If your business applies a blanket rule (e.g. “no part-time roles” or “everyone must be in office 5 days”) you could be exposed to an indirect discrimination argument unless you can objectively justify the rule as a proportionate way to achieve a legitimate business aim.

This doesn’t mean you must accept every request. It does mean you should:

• consider each request on its merits
• consult properly
• explore alternatives before refusing
• document your reasoning clearly

2) Accidentally Changing The Employment Contract

If you agree to a new working pattern, you may be agreeing to a contractual change. That can affect:

• hours of work
• place of work
• salary (if hours reduce)
• availability requirements
• overtime expectations

To avoid disputes later, confirm changes in writing and update the contract or issue a written variation. If you’re making wider changes across the business (for example, moving to a hybrid model), it’s especially important to keep documentation consistent across the team.

3) Working Time, Breaks, And “Always On” Culture

Flexible hours can blur boundaries. If someone starts earlier, finishes later, or is answering messages at night, you can drift into working time issues without realising it.

It’s worth checking your practices against the Working time rules, particularly if you operate shift work, have peak season demands, or rely on overtime.

Even if employees like the flexibility, you should still set clear expectations about:

• core hours and availability windows
• rest breaks and minimum rest periods
• how overtime is approved
• handover and cover arrangements

4) Data Protection And Security For Remote Work

Remote work often means more devices, more cloud tools, and more opportunities for mistakes (like forwarding work files to personal accounts).

From a compliance perspective, you’ll want to think about:

• device security (laptops, phones, password standards)
• handling customer and employee personal data
• use of messaging apps and personal email
• what monitoring (if any) occurs and how it’s communicated

If staff use personal phones for work, it’s worth pressure-testing your approach against common GDPR traps and setting ground rules early.

You can also reduce risk by having an Acceptable Use Policy that spells out what’s allowed on company systems (and what isn’t), especially if your team works across different locations.

What Policies And Documents Should You Have In Place?

The smoother your flexible working process is, the less time it drains from the business. Good documentation is a big part of that - not because you want to be bureaucratic, but because you want consistency.

For many small businesses, the practical “flexible working toolkit” includes:

• a written flexible working policy (process, timelines, decision criteria)
• employment contracts that clearly cover hours, location, and variation of terms
• remote/hybrid working guidelines (security, expenses, equipment, availability)
• IT and data use rules (devices, passwords, monitoring approach)
• manager guidance on handling requests consistently and documenting decisions

If you’re growing and starting to manage these issues across multiple team members, a Staff Handbook can make your workplace expectations much clearer (and reduce the chance that each manager “makes it up” differently).

Should You Offer An Appeal Process?

An appeal isn’t always legally required for every flexible working outcome, but offering one can be a smart risk-management move. It shows reasonableness and can help resolve misunderstandings before they escalate into grievances.

In a small business, an “appeal” might simply mean:

• a second meeting with another manager or the owner, and
• a written final decision with clear reasons.

What matters is that the employee feels heard, and you can demonstrate a fair process.

• You must handle requests in a reasonable manner, including consulting with the employee before refusing, and giving a decision within two months (unless extended by agreement).
• You can refuse a request, but only for recognised business grounds and you should be able to explain the decision clearly and keep records.
• The biggest risks for small businesses are usually inconsistency, discrimination exposure, and accidentally changing contractual terms without documenting it.
• Flexible working arrangements should be supported by practical documentation, including a clear policy, well-drafted contracts, and sensible IT/data rules.
• Getting your process right early helps you stay compliant, keep the team running smoothly, and protect your business as it grows.
