TL;DR
UK remote-working tribunal cases fell in 2025, for the first time since Covid. Employment lawyers split on whether it's weaker worker bargaining power or the strengthened right to request flexible working that landed in April 2024. Both are probably true. But the important shift: employers now face real procedural costs for refusing flexible working without documented reasons. This post covers what changed in the law, what tribunals are actually ruling, and the framing that makes a flexible working request much harder to refuse.
I've been building CVPilot, an AI CV optimisation tool for UK job seekers, and one pattern stands out from the people who've successfully renegotiated flexible working in the past year: they all wrote their request as a business case, not a preference.
The tribunal drop is the signal, not the story. The story is that employer-side risk rose sharply in 2024.
What changed in UK flexible working law
Three substantive changes, April 2024 and early 2025:
1. Day-one right to request
Previously employees needed 26 weeks of service before they could formally request flexible working. Now the right applies from day one. This shifted the negotiation dynamic at hiring and early probation.
2. Two requests per year
Employees can submit two formal requests in any 12-month period, up from one. The first sets the baseline. The second can refine it.
3. Employer duty to consult
Employers can no longer simply refuse. They must consult with the employee about alternatives before refusing. A refusal without documented consultation now carries tribunal risk.
The practical effect: the cost of saying "no" increased. That's why tribunal caseload dropped. Many requests that would have escalated in 2022 now settle in the consultation phase.
What tribunal rulings are actually saying
| Ruling | Implication for employees |
|---|---|
| Refusal without business-case analysis fails the statutory test | Ask for written reasons. If vague, you have grounds. |
| "Company culture" alone is not sufficient | Employers must name specific operational impacts |
| Refusing female employees where male colleagues have similar arrangements risks discrimination claim | Employer must show the decision would have been identical regardless of protected characteristics |
| Unilaterally revoking an existing arrangement requires consultation | Hybrid workers gained protection |
These don't guarantee every request succeeds. They mean the decision process now carries legal risk if it's informal, inconsistent, or undocumented.
Where the negotiating power is now
Three factors determine leverage in 2026:
Does the company have a written policy? Large employers (over 250 staff) typically do. Your request should address their named criteria directly. Small employers often don't, which increases leverage because they can't point to "the policy".
Are others in your team already flexible? If colleagues have similar arrangements, refusal creates consistency risk, especially around discrimination.
Can you document business benefit? Not "I'd prefer". But "Working from home Tuesdays and Thursdays would let me start at 8am instead of 9:15am. That's 6 extra productive hours per month."
The framing that actually works
Weak request
I'd like to work from home on Mondays and Fridays as it would help me with personal errands and commuting costs.
Strong request
I am requesting to work from home on Mondays and Fridays starting from [date], with Tuesdays, Wednesdays, and Thursdays in the office. This arrangement would support 3 full days of in-person collaboration including our sprint planning (Tuesday) and customer review (Thursday). Home days would cover the focused analytical work where I currently lose 2-3 hours per week to interruptions. I have attached a 30-day trial plan with clear metrics.
Three things the strong version does that the weak version doesn't:
- Names the business benefit in measurable terms
- Shows awareness of which days require in-person collaboration
- Offers a structured trial that makes it easy for the employer to say yes
If your employer refuses
Vague refusal: Request specific reasons in writing, referencing the employer's statutory duty. This often prompts reconsideration.
"Business need" refusal: Ask for the specific operational impact, propose a trial addressing it. Employers often refuse on anticipated problems that trials can disprove.
Refusal inconsistent with colleagues: Document the inconsistency, raise formally with HR. Discrimination risk rising.
Nothing moves: ACAS Early Conciliation. Free, usually resolves within 6 weeks, signals seriousness without committing to litigation.
How this affects your next job search
Flexible working is now a statutory day-one right to request. Concretely:
- You can request flexibility in your first week of a new role
- You don't have to wait for "proving yourself"
- The offer stage is the best time to negotiate, because the employer's cost to rewrite the offer is low
On your CV, explicitly mention flexibility you've maintained successfully. Not as a demand, but as evidence: "Managed a hybrid schedule delivering £400,000 of annual cost savings while working from home 3 days per week."

Anyone here successfully negotiated flexibility from day one of a new role? Curious what framing landed.
