Trade Union Access Requests and How to Prepare
October 23rd 2026 | Posted by Jo Thompson
Trade union access requests are heading for HR desks and many employers have not decided who opens the first. HR Recruit hosted a virtual boardroom to help. Employment lawyers Vicky Roberts of Lead-ER and Catherine Wilson of Constantine Law mapped out what lies ahead.
“Getting an access agreement in place is not an end in itself, it’s a means to an end.”
Trade Union Access Requests Timeline
Any independent trade union holding a certificate of independence can ask, whether it has members on site. The request must be written and may seek physical entry or digital contact, though never for industrial action. It should state the type of access, how often it will happen and the notice the union proposes.
Employers get 15 working days to respond and then 25 working days to negotiate. Any refusal needs reasons, including naming another recognised union. A union may then apply to the Central Arbitration Committee, no later than 55 working days after the request. That equals roughly 11 calendar weeks and extensions need agreement from both sides.
Handling Trade Union Access Requests Internally
Nobody wants a request lost at a distant site, so both speakers urged firms to brief local managers. The code of practice also suggests publishing a dedicated email address for union approaches.
Negotiation Boundaries
A fictional employer with 190 staff across ten sites showed how trade union access requests can overreach. Its visiting union wanted the following.
- Internal email: Unrestricted use of company systems alarmed Catherine, who pointed to data protection and suggested a ring-fenced opt-in site.
- Field team meetings: Hosting sessions in a manager’s home felt uncomfortable, while an external venue raised the question of who pays.
- A permanent room: Ad hoc rooms already serve disciplinary support, so a dedicated space seemed excessive.
- A three year term: The committee cannot impose more than two years.
Vicky noted that model terms point towards weekly access, which she considered generous. Entry to private homes is barred and employers with fewer than 21 workers are exempt, counting agency staff. Catherine added that large employers make attractive targets, since union officials are scarce and expensive.
Voluntary Agreements
Catherine expects the committee to bring chronic uncertainty because it can make its own rules. Repeated breaches carry fines of £75,000 then £150,000 and £500,000. She favoured negotiating a voluntary deal, even if some red lines shift. Written agreements should also help, since employers have historically documented arrangements poorly.
Vicky described the intent plainly, saying “It’s trying to force the parties to talk rather than go to law.”
Audience Questions
Delegates asked whether recognised unions must use this route. Vicky said no, although new employee groups on existing sites could still qualify. Customer premises came up too, where a third party must agree and its security rules bind visiting officials.
Catherine believed staff working abroad but tied to the UK would count towards the 21-worker threshold. She expected digital access to dominate for home-based teams, though Vicky called its likelihood the million-dollar question.
In Summary
Trade union access requests reward preparation over reaction. Know the deadlines, brief managers likely to receive one and test every wish list against committee limits. Voluntary agreements give employers more control than imposed terms. Clear written arrangements then protect everyone once a union comes calling. Settling who owns incoming requests early lets teams respond calmly within tight deadlines.
