Flexible Working Requests: Your Day-One Right and the Pay Impact 2026
Since April 2024, every employee has the right to request flexible working from their first day of employment — but a move to reduced hours changes your pay, pension contributions and holiday entitlement pro rata. Here is what to check before you ask in 2026.
A stronger right to ask — not a guaranteed outcome
Since April 2024, every employee can request flexible working from their very first day in a job, can make up to two requests in any 12-month period, and must receive a response (including proper consultation before any refusal) within two months. This is a meaningfully stronger process than before, but it remains a right to request, not a right to automatically receive — employers can still say no for a defined set of business reasons.

Open Pro-Rata Salary calculatorThe eight statutory grounds for refusal
| Ground | Example |
|---|---|
| Burden of additional costs | Reorganising cover would require hiring extra staff |
| Detrimental effect on ability to meet customer demand | Reduced coverage during peak business hours |
| Inability to reorganise work among existing staff | No practical way to redistribute the role's core duties |
| Inability to recruit additional staff | Specialist role, hard to backfill remaining hours |
| Detrimental impact on quality | Role requires continuous, uninterrupted coverage |
| Detrimental impact on performance | Genuine, evidenced performance concern with the proposed pattern |
| Insufficient work during proposed times | No genuine workload during the requested working pattern |
| Planned structural changes | Business restructuring already underway affecting the role |
Worked example 1: moving from 5 days to 4 days
Priya, on a £36,000 full-time salary, has her flexible working request approved to move from 5 days to 4 days a week.
| Item | Full-time (5 days) | New pattern (4 days) |
|---|---|---|
| Annual salary | £36,000 | £28,800 (80% pro rata) |
| Statutory holiday entitlement | 28 days | 22.4 days (often rounded to 22 or 23) |
| Pension contribution (5% employee, illustrative) | £1,800/year | £1,440/year |
| Employer pension match (3%, illustrative) | £1,080/year | £864/year |

Tom, a customer service team member, requests to work exclusively 9am-1pm each day (a significant reduction from his full 8-hour shifts), but his employer refuses, citing detrimental impact on ability to meet customer demand during peak afternoon call volumes, after genuinely consulting with him about alternative patterns.
| Step | Outcome |
|---|---|
| Request submitted | Considered within the 2-month window |
| Consultation | Employer discusses alternative patterns with Tom before deciding |
| Outcome | Refused on a specified statutory ground, following proper process |
Provided the employer has genuinely considered and consulted on the request, and the stated ground is a legitimate business reason, this refusal is likely to be lawful, even though it is disappointing for Tom.
Worked example 3: hybrid working request, no pay change
Fatima requests to work from home three days a week, keeping her existing 5-day, full-time hours and salary unchanged, only altering where the work is done.
| Item | Effect |
|---|---|
| Salary | Unchanged — no reduction, since hours are unchanged |
| Pension contributions | Unchanged |
| Holiday entitlement | Unchanged |
This illustrates that not all flexible working requests affect pay — location and pattern changes without a reduction in total contracted hours generally leave salary, pension and holiday entitlement untouched.

Frequently asked questions
Can I request flexible working from my first day in a new job?
Yes — since 6 April 2024, the right to request flexible working applies from day one of employment, removing the previous requirement to have worked for an employer for at least 26 weeks before making a request. This is a right to request, not a right to receive — an employer can still refuse for one of the specified statutory business reasons.
How many flexible working requests can I make in a year?
Employees can now make two statutory flexible working requests in any 12-month period, up from one previously. Employers must respond within two months (down from three) unless a longer period is agreed, and must consult with the employee before rejecting a request, rather than being able to simply refuse in writing without discussion.
What counts as 'flexible working' under this right?
It covers a wide range of arrangements: changes to hours (part-time, reduced hours), changes to when hours are worked (compressed hours, flexitime, staggered start/finish times), changes to where work is done (home or hybrid working), and job-sharing arrangements, among others.
On what grounds can an employer refuse a flexible working request?
An employer can still refuse for one of eight specified statutory business reasons, including: burden of additional costs, inability to reorganise work among existing staff, inability to recruit additional staff, detrimental impact on quality or performance, detrimental effect on ability to meet customer demand, insufficient work available during the proposed working times, or a planned structural change to the business. The employer must genuinely consider the request and consult before refusing, rather than issuing a blanket refusal.
How does moving to reduced hours affect my pay?
Your salary is generally reduced pro rata to the change in your contracted hours or days — for example, moving from 5 days to 4 days a week (an 80% pro rata fraction) typically reduces your salary to 80% of the full-time equivalent, assuming your daily rate stays the same and only the number of days changes.
Does reduced-hours working affect my pension contributions?
Yes, generally — both your own contribution and your employer's matching contribution (commonly calculated as a percentage of pensionable pay under auto-enrolment) are usually reduced pro rata alongside your lower salary, since contributions are typically a percentage of actual pay, not a fixed amount, unless your specific scheme has different rules.
Does reduced-hours working affect my holiday entitlement?
Yes — statutory minimum holiday entitlement (5.6 weeks a year, capped at 28 days for a full-time worker) is pro-rated based on your reduced hours or days, in the same way pay is. Moving from 5 days to 4 days a week typically reduces your holiday entitlement from 28 days to 22.4 days (5.6 weeks × 4 days), often rounded to 22 or 23 days depending on your employer's specific policy.
Could requesting flexible working affect my future promotion prospects or job security?
Legally, employers must not treat a flexible working request itself as grounds for less favourable treatment, and doing so could amount to indirect discrimination in some circumstances (particularly relevant to requests linked to caring responsibilities, disability, or other protected characteristics). In practice, informal cultural attitudes toward flexible working vary between employers, so it can be worth having an open conversation with your manager about how a change might be perceived, alongside understanding your formal legal protections.
What happens if my employer doesn't respond within the required timeframe?
An employer who fails to respond within the required period (two months, unless a longer period is agreed) or fails to follow the proper process (including consulting before any refusal) may be in breach of the statutory flexible working procedure, which can potentially be raised via a grievance or, in some circumstances, an employment tribunal claim, though the specific remedies available are generally procedural (such as a limited compensation award) rather than a right to have the request automatically granted.
