What the Employment Rights Act 2025 means for your business

Key changes SME leaders need to understand to stay compliant and manage risk

For many SME leaders, employment law can feel like something that sits in the background, until it suddenly doesn’t. The Employment Rights Act 2025 is one of the most significant updates to UK employment legislation in decades, and it will have a direct impact on how you recruit, manage, and retain your people.

Following our recent webinar with Loch Associates, this article breaks down the key changes and what they mean in practice for small business owners. You can also watch the There is also a link to the full webinar recording below, to provide you with a deeper dive into each area.

A shift towards greater employee protection

At its core, the act strengthens employee rights and increases employer accountability. While many of the changes are being introduced in phases through to 2027, the direction of travel is clear: more protection for workers, and more responsibility on employers to demonstrate fairness, transparency, and compliance.

For SMEs, this means reviewing not just policies, but day-to-day management practices.

Unfair dismissal: a shorter timeline, higher risk

One of the biggest changes is the reduction of the qualifying period for unfair dismissal claims from two years to six months (expected from January 2027).

At the same time, the cap on compensation for unfair dismissal is being removed, meaning potential payouts could be significantly higher.

What this means for SMEs:

• Probation periods become much higher risk
• Dismissals must be well-documented and procedurally fair
• Manager capability becomes critical

In practical terms, the ‘trial period’ for employees is shrinking, and businesses will need to get hiring decisions right much earlier.

‘Fire and rehire’ practices under scrutiny

The act makes it automatically unfair to dismiss employees for refusing changes to key contract terms, or to replace them with someone on different terms, unless the business is in severe financial distress.

What this means for SMEs:

• Contract changes will require genuine consultation
• Restructuring becomes more complex
• Shortcuts carry significant legal and reputational risk

For growing businesses that regularly adapt roles or working patterns, this is a major shift.

Zero-hours contracts and agency workers

The act introduces new rights for workers on zero- or low-hours contracts, including:

• The right to request guaranteed hours based on actual working patterns
• The right to reasonable notice of shifts
• Compensation for short-notice cancellations

What this means for SMEs:

• Reduced flexibility in workforce planning
• Increased administrative and payroll complexity
• Potential cost increases

If your business relies on seasonal or flexible labour, it may be worth reviewing whether current models remain viable.

Flexible working: more scrutiny on decisions

Flexible working is already a day-one right, but the Act raises the bar by requiring employers to show that any refusal is reasonable and justified.

What this means for SMEs:

• Informal refusals are no longer enough
• Decisions need clear business reasoning
• Documentation becomes essential

This is likely to increase tribunal risk if processes are not followed carefully.

Changes to sick pay and family leave

From April 2026, Statutory Sick Pay (SSP):

• Will be paid from day one (no waiting period)
• Will be available to lower earners

There are also expanded day-one rights to parental and paternity leave.

What this means for SMEs:

• Increased short-term cost exposure
• Greater need for absence management systems
• More emphasis on wellbeing and retention

A new enforcement body: the Fair Work Agency

The Act introduces the Fair Work Agency (FWA), with powers to:

• Inspect workplaces
• Enforce holiday pay and statutory payments
• Issue penalties of up to 200% of underpayments
• Bring claims on behalf of workers

What this means for SMEs:

• Compliance becomes more actively enforced
• Record keeping must be accurate and audit-ready
• Errors are more likely to be challenged

This represents a shift from reactive to proactive enforcement.

Redundancy and trade union changes

The act also expands collective redundancy obligations, including:

• New thresholds across multiple sites
• Increased penalties for non-compliance (up to 180 days’ pay per employee)

Alongside this, trade unions will gain greater access to workplaces and stronger protections for industrial action.

What this means for SMEs:

• Workforce restructuring requires more planning
• Multi-site businesses face greater complexity
• Employee relations will play a bigger role

What should SME leaders do now?

While some of the biggest changes won’t land until 2027, businesses should start preparing now to ensure that changes can be rolled out in a controlled way.

Key actions include:

• Reviewing recruitment and onboarding processes
• Training managers on performance, conduct and documentation
• Auditing contracts, policies and working practices
• Strengthening HR systems and record keeping
• Stress-testing workforce models (especially flexible labour)

Above all, the act reinforces a simple principle: good people management is no longer optional, it’s a legal necessity.
