The Employment Rights Act 2025 UK startups must now navigate lands in two waves. The first hits on 6 April — ten days away. From that date, legally binding changes alter how UK employers manage sick pay, redundancy, and family leave. A second, larger wave follows in January 2027. Both carry material cost and governance implications for VC-backed portfolios and their boards.

Key Points

• 6 April 2026: Statutory Sick Pay payable from day one; protective redundancy awards double; new day-one family leave rights take effect; holiday pay records become mandatory.
• 1 April 2026: National Minimum Wage rises to £12.71 per hour for workers aged 21+.
• 7 April 2026: The Fair Work Agency launches, consolidating enforcement of holiday pay, sick pay, and minimum wage compliance.
• January 2027: Unfair dismissal qualifying period drops from two years to six months; compensation cap removed entirely. Any employee hired from July 2026 onwards falls within this regime from January 2027.
• Government estimate: Total employer cost revised to approximately £1 billion per year (HM Government Economic Analysis, January 2026).
• CIPD Winter 2025/26 survey (2,082 UK HR decision-makers): The Act described as a handbrake on hiring.

Employment Rights Act 2025 UK Startups: Background and Context

The Employment Rights Act 2025 UK startups and their boards are now working through received Royal Assent on 18 December 2025 — after over 600 parliamentary amendments and months of procedural back-and-forth between the Houses. The final Act runs to more than 300 pages of primary legislation. That is before the secondary legislation and the 26 expected government consultations still in progress through 2026.

The stated goal is straightforward: reduce insecure work and reset the employer-employee balance. The practical effect for early-stage companies is a multi-front compliance obligation arriving at a moment when the UK startup environment is already under significant cost pressure. The changes are phased across 2026 and 2027. The April wave contains the most operationally immediate requirements.

What Changes on 6 April 2026

Statutory Sick Pay (SSP) For Employment Rights Act 2025 UK startups and their workforce, the three-day waiting period before SSP is payable is abolished. From 6 April, SSP is owed from the first day of a sickness absence — at £123.25 per week or 80% of the employee’s normal weekly earnings, whichever is lower (GOV.UK, 2026). The lower earnings limit that previously excluded lower-paid staff from qualifying is also removed. There is no rebate scheme for small businesses. None.

Collective Redundancy — Protective Awards The maximum protective award for failure to collectively consult before redundancy doubles from 90 days’ pay to 180 days’ pay per affected employee. For VC-backed companies that have gone through headcount reductions in the past 18 months, this materially changes the financial exposure attached to any process failure in future restructuring events.

Day-One Family Leave Rights Paternity leave and unpaid parental leave become day-one rights for all employees. Previously, paternity leave required 26 weeks of service; unpaid parental leave required 12 months. The Bereaved Partners’ Paternity Leave also comes into force on 6 April, entitling bereaved fathers and partners to up to 52 weeks of leave if the mother or primary adopter dies within the first year of the child’s life.

Holiday Pay Record-Keeping From 6 April, employers must maintain formal records of annual leave and holiday pay. This is a compliance requirement — not a best practice recommendation. Portfolio companies without formalised HR systems need to act before the deadline.

Whistleblowing — Sexual Harassment Reporting workplace sexual harassment becomes a qualifying disclosure under whistleblowing law from 6 April. Employees making such disclosures gain employment protections against detriment and dismissal.

National Minimum Wage Five days earlier — from 1 April 2026 — the National Minimum Wage rises to £12.71 per hour for workers aged 21 and over. The 18–20 age group rate rises to £10.85. Startups with junior or customer-facing roles that have not yet updated payroll are already behind.

Who Is Affected — and the Specific Startup Exposure

The Employment Rights Act 2025 UK startups operate under has no size exemption. It applies to all UK employers. For VC-backed companies, the April wave concentrates into three specific areas of exposure.

Cost-base recalibration. Higher SSP obligations, doubled redundancy penalty risk, and NMW increases add to the per-head employment cost. These flow directly into operating expenditure projections and runway calculations. Investors reviewing Q2 2026 board packs should expect updated headcount cost assumptions — if they have not already received them.

Restructuring risk. Doubling the collective redundancy protective award changes the financial risk profile of any future reduction-in-force. Companies restructuring in 2026 face twice the exposure on process failures compared with 2025. The margin for procedural error has halved.

Governance burden. Holiday pay records, whistleblowing policy updates, and revised family leave documentation require HR infrastructure that many early-stage companies have not formalised. The Fair Work Agency launches on 7 April 2026 with direct enforcement powers over holiday pay, sick pay, and minimum wage compliance. This is not an advisory body. It has teeth.

Analysis: The Policy Stack Raising Startup Risk in 2026

The Employment Rights Act does not sit in isolation. It lands on top of the compounding regulatory risk facing UK startups in 2026 — a policy environment that has been progressively raising the cost of building and operating in the UK across the current Parliament.

The government’s own economic analysis estimates the Act will cost employers approximately £1 billion per year in aggregate. That headline obscures the distributional reality. Large corporates have HR infrastructure, legal teams, and payroll systems designed to absorb regulatory change — the Employment Rights Act 2025 UK startups face lands asymmetrically. Early-stage companies do not. The compliance burden as a proportion of operational capacity is structurally larger for startups — and the cost lands hardest on those scaling headcount fastest.

This matters acutely in the context of the structural pressures already compressing UK VC fund economics in 2026. A higher cost base at portfolio level, arriving simultaneously with blocked exit routes, compresses margins and deepens the runway pressure that fund managers are already managing. These are not separate problems. They are compounding ones.

The January 2027 Wave — Why Hiring Decisions Made Now Matter

The most consequential provision in the Employment Rights Act does not come into force until January 2027. From that date, the unfair dismissal qualifying period drops from two years to six months — and the compensation cap on tribunal awards is removed entirely.

The exposure clock, however, starts sooner. Any employee hired from 1 July 2026 will have accrued six months of service by 1 January 2027, and will fall within the new regime on the day it takes effect. This is the Employment Rights Act 2025 UK startups scaling in H2 2026 cannot afford to miss — hiring decisions from July carry a fundamentally different risk profile to those made today.

For VC-backed companies planning to scale headcount in H2 2026 — and many are, aligned to post-round deployment timelines — this is a board-level governance question. The cost of a mis-hire in a senior role, under the new regime, is uncapped. Current tribunal awards are capped at £118,223 or 52 weeks’ pay, whichever is lower (GOV.UK). From January 2027, there is no ceiling. The figure that appears in a tribunal award for a wrongly handled senior termination becomes entirely open-ended.

This stacks alongside carried interest tax changes already affecting UK fund manager economics, as the cumulative regulatory and tax burden continues to reshape the economics of building and backing companies in the UK this year.

Timeline and Next Steps

The full schedule of changes under the Employment Rights Act 2025 UK startups and their boards must plan for is set out below.

Immediate actions for UK startups and their boards:

1. Update SSP policy and payroll configuration before 6 April.
2. Review collective redundancy procedures against the doubled protective award exposure.
3. Confirm paternity and parental leave policies reflect day-one eligibility.
4. Implement formal annual leave and holiday pay record-keeping before 6 April.
5. Brief HR leads on the revised whistleblowing policy requirements.
6. Begin reviewing probationary and performance management processes now, ahead of July 2026 hiring decisions — the January 2027 unfair dismissal change requires robust documentation from day one of employment.

Secondary legislation for several of these provisions remains in active consultation through Q2 2026. Legal counsel should be engaged before significant headcount changes are made.
