Your office manager is spending about twelve hours a week chasing documents, filing client records, and rekeying data across three systems that do not talk to each other. When she is out, one of the directors picks it up badly: things slip, clients notice. The MTD quarterly filing deadline is next week. The ICO renewal reminder has been sitting in her inbox unread for three weeks. Two new client onboardings are queued and nobody has touched the folders yet. The rational response seems obvious: hire someone to share the load. Post the job, interview, start them in July.
Here is what most businesses have not clocked yet. Under the current rules, a new hire needs two years of continuous service before they can bring an unfair dismissal claim. That window has protected employers for decades. From January 2027, it is gone.
The Employment Rights Act 2025 small business hiring risk has just shifted sharply. The qualifying period for unfair dismissal drops from two years to six months. The compensation cap, currently set at £123,543 or 52 weeks' gross pay (whichever is lower), is being removed at the same moment. Both changes are confirmed in the Employment Rights Act 2025 guidance on Acas.
If you hire someone this summer, their unfair dismissal protection lands seven months into the job. Not two years. Seven months. With no statutory ceiling on what a tribunal can award.
What the Employment Rights Act 2025 small business hiring calendar looks like now
Under the old rules, a hire made in July 2026 would have gained unfair dismissal protection in July 2028. Two years out. Plenty of time to manage performance, run a fair process, and decide whether the fit was right.
Under the Employment Rights Act 2025, small business owners are looking at a very different calendar. Anyone hired before July 2026 will already have six or more months of service by 1 January 2027. They gain unfair dismissal protection from that date, because prior service counts toward the new six-month threshold.
A July 2026 hire reaches six months in January 2027 and gains protection at the same moment. Anyone hired after that gains protection when they hit their own six-month mark.
The probation period used to sit comfortably inside the two-year safety window. Now it sits at the very edge of the tribunal window.
What the compensation cap removal means in plain numbers
Currently, unfair dismissal compensation is capped at the lower of £123,543 or 52 weeks' gross pay. For a £35,000-a-year employee, the practical ceiling is roughly £35,000.
From 1 January 2027, there is no cap.
That changes the risk profile of any marginal hiring decision. If a tribunal finds a dismissal unfair and the process was handled poorly, the award is not constrained by statute. For a business with limited cash reserves, a disputed dismissal at month seven, conducted without a paper trail, could result in a claim that is genuinely costly to defend, let alone lose.
Employment tribunals can take the better part of a year before a hearing date. A disputed dismissal in early 2027 sits on your books for much of the financial year.
The qualifying period change and its retrospective application are covered in detail on the government's employer campaign page.
Why your probation period no longer works the way you think
A probation period is an HR tool, not a legal shield. It has never, by itself, removed a statutory right from an employee. What it relied on was the fact that the two-year qualifying period covered the first 24 months of employment anyway.
That cover is no longer there.
Under the new regime, an employee whose probation ends at six months has simultaneously reached the point at which unfair dismissal protection applies. The moment you decide to end the employment is now the same moment their right to challenge that decision becomes legally enforceable.
This does not mean you cannot dismiss someone in their first year. It means every dismissal from month six onwards needs to be handled as if it is full tribunal territory: documented concerns, written warnings where appropriate, a structured process, and a genuine opportunity for the employee to respond. Without that paper trail, a dismissal that was previously clean is now arguable.
The maths on a new hire have moved
Before April 2025, the total cost of a hire was roughly: salary, employer's NIC at 13.8%, pension, and tools. The legal risk sat two years away.
The picture has changed in two waves since then. From April 2025: employer NIC rose to 15% on earnings above £5,000, down from the previous £9,100 secondary threshold. From April 2026: the National Living Wage reached £12.71 per hour for workers aged 21 and over. Statutory Sick Pay became a day-one right, with no waiting period and no lower earnings limit. Paternity leave and unpaid parental leave also moved to day-one entitlements.
For a £30,000 hire, the employer cost is roughly £34,000: the salary, plus £3,750 employer NIC (15% on earnings above £5,000), plus around £700 auto-enrolment pension contribution. That figure does not include tools, onboarding time, or the two to three months where a new hire runs at roughly 60 per cent of full pace while they find their feet. Factor those in and the effective year-one cost is closer to £40,000 before the Employment Rights Act changes the risk side of the ledger.
From month six, the legal breathing room that used to give employers runway to manage poor performance has been cut to nothing.
The question worth asking before you post the job
What portion of this role is genuinely irreducible human work?
Most admin-heavy roles split roughly like this: 30 to 40 per cent is relationship or judgement work that actually needs a person. The other 60 to 70 per cent is deterministic, pattern-based, and repeatable. The copying, the filing, the chasing, the rekeying across systems that nobody loves but everyone does.
That second portion is automatable. Not with off-the-shelf software that is 80 per cent wrong and charges per seat, but with a Python script written for your specific workflow, that pulls from the sources your team already uses and surfaces a short summary for a person to check.
The hire you were planning to handle the growing admin volume can then focus on the 30 to 40 per cent that actually needs them: the customer calls, the tricky conversations, the relationship-dependent decisions. That is a different shape of role. It is also a more defensible one under the new hiring regime, because the person in it is genuinely harder to replace with a script.
Where the bureau draws the line
The Employment Rights Act 2025 small business compliance picture has two distinct questions inside it, and collapsing them is expensive.
The first is legal: what constitutes a fair dismissal process, what probationary documentation you need, how to manage performance under the new regime. That is for your employment solicitor or HR advisor. Not the bureau.
The second is operational: which parts of the admin-heavy role you were about to hire for can be automated, how that automation integrates with the systems your team already uses, and how you keep headcount lower without the work piling up. That is the bureau's territory.
The bureau does not interpret employment law. It builds the workflow that means you need fewer hires facing that law.
What the bureau builds for businesses stuck in this position
Take a 12-person services firm that needs someone to manage client onboarding admin: pulling details from the intake form, chasing outstanding documents, creating the shared folder, raising the invoice, logging the record in the CRM. Currently half a day of someone's time per new client.
The bureau builds a Python automation that takes the form submission, creates the folder structure, fires the document-request email on a defined schedule, raises the invoice when the trigger conditions are met, and logs the record. It runs overnight and outputs a short status report by 8am.
The remaining human role: review the report, make any calls that need a voice, handle the exceptions. That is two hours a week per ten new clients. Not a hire. The bureau builds that for a fixed fee of around £4,000, against £34,000 a year in salary and NIC for the hire you were about to make.
That business automation also ties into whatever else the bureau is tracking for the business: the MTD quarterly update window, the ICO renewal reminder, the next confirmation statement deadline. One system, not four spreadsheets. The person you were about to hire stays focused on the work that actually needs them.
If that description does not sound like something you could put together over a weekend, that is the point. The build is specific to your workflow, tested against your tools, and documented so it runs without babysitting.
