Employment law is not usually thought of as a finance topic. But the reforms that have come into force in 2026 — and those arriving in January 2027 — have a direct line into your payroll costs, your cashflow model, and your risk exposure as an employer. Getting across the right resources now, before the costs hit unexpectedly, is exactly the kind of planning that separates businesses that stay ahead of the curve from those that scramble to catch up.

We work with UK SMEs across a range of sectors, and the pattern we see consistently is that employment-related costs are among the least well-modelled items in a management accounts pack. Most owners know their rent, their software subscriptions, and their cost of goods — but statutory entitlements tend to live in someone's inbox rather than a forecast. This post is a practical orientation to what has changed in 2026, what is coming in 2027, and what the financial planning implications look like for a growing business.

Two significant changes took effect in April 2026, both affecting statutory entitlements that feed directly into your payroll runs.

Statutory Sick Pay reform

Statutory Sick Pay (SSP) now has no lower earnings threshold and no three-day waiting period. Previously, employees needed to earn above a minimum weekly amount before SSP applied, and the first three qualifying days were unpaid. Both of those filters have now gone. In practice, this means a broader population of your workforce is eligible for SSP from day one of absence — including part-time employees and lower-paid workers who would previously have fallen below the threshold.

For most businesses with a small headcount this will not produce a dramatic cost spike in any single month. But across a year, with several employees and a normal pattern of short-term absences, the cumulative cost is higher than it was under the old rules. If your cashflow model does not reflect the updated SSP position, it is worth revisiting.

Paternity leave and unpaid parental leave from day one

From April 2026, employees are entitled to Paternity Leave and Unpaid Parental Leave from their first day of employment — there is no longer a qualifying service requirement. This is a meaningful change for businesses that hire frequently or carry a younger workforce. It removes what was effectively a probationary buffer on parental rights, and it means your HR and payroll processes need to be ready to handle these entitlements for new starters from the moment they join.

Alongside the April 2026 entitlement changes, the government has established the Fair Work Agency — a new body tasked with upholding workers' rights and supporting businesses with compliance. This is not simply a rebranding exercise. The creation of a dedicated enforcement agency signals a clear shift in how seriously the government intends to pursue employment rights compliance, including among smaller employers who might previously have attracted little scrutiny.

For SMEs, the practical message is straightforward: the expectation that small businesses can quietly operate outside the rules — whether intentionally or through administrative gaps — is becoming harder to sustain. The resources you invest in getting your payroll and HR processes right are increasingly also your risk-management spend.

It is also worth noting that February 2026 brought revised rules around trade union requirements, including simplified procedures related to industrial action. Most SMEs will not be directly affected by this, but businesses in sectors with stronger union representation — certain areas of hospitality, logistics, or public-facing services — should be aware that the framework has shifted.

We are not employment lawyers, and if your business has complex workforce arrangements, specialist legal advice is the right starting point. But from a management accounting perspective, we would always encourage clients to treat compliance costs as a planned line item rather than a reactive one.

The most significant change still to come is the revision to unfair dismissal protections, scheduled for 1 January 2027. The details of the reform are still being worked through at a policy level, but the direction of travel is clear: the threshold for qualifying service that currently gates access to unfair dismissal claims is expected to be significantly reduced or removed.

At present, employees generally need two years of continuous service before they can bring an unfair dismissal claim. A change to that threshold — potentially from day one of employment — would fundamentally alter the risk calculus for businesses when managing performance, probation periods, and exits.

From a finance and planning perspective, the implication is that businesses need to start reviewing their employment policies and processes now, not in December 2026. A poorly managed exit that results in a tribunal claim is a cost that sits nowhere in most SME budgets — legal fees, management time, potential settlement costs, and reputational exposure. None of those are pleasant surprises in a management accounts review.

We would encourage any SME with five or more employees to use the period between now and the end of 2026 to review their probation processes, documentation standards, and how they handle underperformance conversations. Getting proper HR resources in place before the change arrives is considerably less expensive than dealing with the consequences afterwards.

The honest answer for most SMEs is that they do not have a clear line-of-sight on what these changes cost them — not because the numbers are huge, but because payroll and HR costs are often managed transactionally rather than analytically.

A useful starting point is to model three things alongside your normal management accounts:

• SSP exposure: Based on your headcount and historic absence patterns, what does your revised SSP liability look like across a twelve-month period? For businesses with higher absence rates — hospitality, care-adjacent services, high-turnover retail — this can be a material number.
• Parental leave frequency: If you have a younger workforce, day-one parental entitlements may affect resourcing and cost more often than you expect. Modelling cover costs or productivity loss from day-one absences is a planning discipline worth building in.
• Unfair dismissal reserve: This is more qualitative, but businesses that carry any meaningful employment risk — high-volume hiring, frequent restructuring, performance management activity — should at minimum have a conversation about what a tribunal claim would cost and whether their processes are robust enough to defend one.

None of this requires a dedicated HR team. But it does require that your finance function — whether in-house or outsourced — is asking these questions proactively rather than waiting for a problem to surface. For clients on monthly management reporting with us, this kind of scenario modelling is a standard part of the conversation.
