Trade Union Recognition Explained: What Changed and What’s Next

In our last article, New Trade Union Rights Are Coming: A Plain-English Guide for Employers, we covered two changes taking effect on 30 October 2026: the new duty to tell staff about their right to join a union, and the new right for unions to request access to your workplace.

This article covers a related change that’s part of the same wider reform programme, but sits on its own timeline — and it’s already happened. It explains how a trade union becomes formally “recognised” in your workplace, and how that process got significantly easier back in April 2026.

A quick explainer of the terms you’ll see

Recognition — when an employer formally agrees to negotiate with a trade union on behalf of a group of employees. Once a union is recognised, the employer must bargain with it on matters like pay and conditions for that group.
Collective bargaining — the process of an employer and a recognised union negotiating terms and conditions together, rather than the employer setting them alone.
Central Arbitration Committee (CAC) — the independent body that decides disputes between employers and trade unions, including whether a union should be recognised when an employer won’t agree voluntarily.
Bargaining unit — the specific group of employees a union is seeking to represent (for example, “all warehouse staff at Site A”).
TULRCA — the Trade Union and Labour Relations (Consolidation) Act 1992, the main existing law on trade unions, which we introduced in our previous article.
Schedule A1 — the part of TULRCA that sets out the step-by-step legal process for statutory recognition.

Two ways a union can become recognised

1. Voluntary recognition. An employer can simply agree to recognise a union, by mutual agreement. There’s no fixed process — it’s a business decision, and it’s the simplest route by far.

2. Statutory recognition. If an employer won’t agree voluntarily, a union can apply to the CAC to force the issue. This only applies to employers with 21 or more UK workers — below that, a union cannot use this route, though voluntary recognition is always still possible.

How the statutory process works

The union proposes a bargaining unit — the specific group of staff it wants to represent — and the CAC checks this grouping makes sense.
The union must show it has enough membership within that group to proceed.
The CAC may order a ballot of everyone in the bargaining unit, asking whether they want the union to represent them.
If the legal tests are met, the CAC formally declares the union recognised, and the employer must then bargain with it on the agreed matters.

What changed on 6 April 2026

This is the part that matters most for employers right now — recognition became noticeably easier to achieve:

Lower membership bar. The union used to need to show 10% membership in the bargaining unit before its application could even be accepted. That 10% figure can now be lowered by the government, by regulations, to as low as 2% — so a much smaller group of members could be enough to start the process.
An extra hurdle removed. Previously, the CAC also had to be satisfied that a majority of the whole bargaining unit was likely to support recognition, on top of the membership figure. That extra test has been scrapped — meeting the membership threshold is now enough on its own.
Ballot threshold lowered. Where a ballot is held, the union used to need both a majority of the votes cast and at least 40% of everyone eligible to vote actually voting yes. Now, a simple majority of those who vote is enough — meaning recognition can succeed even with lower turnout than before.

Put together, these three changes mean recognition can now happen with less visible support than it could a year ago, and with fewer opportunities for an employer to block the process on procedure.

This has already come into force. It applies to any application the CAC has received since 6 April 2026, with some protection for cases that were already underway before that date.

Why this matters even more alongside the October changes

This is where the pieces connect. As we covered in our previous article:

From 30 October 2026, unions can request access to your workplace — even where they currently have no members — specifically to recruit and organise.
From the same date, you must tell staff in writing that they have the right to join a union in the first place.

Put the three reforms together, and the pattern is clear: it’s now easier for a union to reach your staff, easier for staff to know their rights, and easier for any resulting membership to convert into formal, binding recognition. Employers who’ve never dealt with a union before should treat 2026 as the year this genuinely becomes a live possibility, not a distant risk.

What you should do now

Know your numbers. If you employ 21 or more people, you’re in scope for statutory recognition — check whether you know your current headcount by site and by role, since bargaining units are often defined this way.
Understand your current position. Do you formally recognise any union anywhere in your business already? If so, on what terms? If not, has anyone ever approached you informally?
Don’t assume “no request yet” means “not a risk.” As we noted with workplace access, a request for recognition can come from a very small starting base of members.
Take any approach seriously and get advice early. If a union does contact you about recognition — formally or informally — how you respond in the first few weeks matters. Missteps early on (for example, around what the law calls “unfair practices” during a recognition campaign) can affect the outcome.
Review this alongside your October preparations. If you’re already updating handbooks and processes for the written statement duty and access requests, it’s the right moment to also make sure your position on recognition is clear and documented.

How Cheviot HR can help

Recognition, access requests and the new statement duty are best thought of as one connected set of changes rather than three separate compliance tasks. We can review where your business currently stands, help you prepare a considered response if a union does make contact, and make sure your documentation is ready across the board.
