TUPE Essentials for Managers: What Happens When a Business Transfers

When a business changes hands, or a service gets outsourced to a new provider, the people doing the work don't just vanish and get re-hired on fresh terms. In most cases, UK law moves their employment across automatically, on the same terms they already had. That's TUPE — the Transfer of Undertakings (Protection of Employment) Regulations 2006 — and if you manage people through one of these changes, understanding what it actually requires is essential. Getting it wrong is one of the more common (and costly) ways employers end up at an employment tribunal.

This isn't a niche issue confined to big corporate mergers. TUPE applies just as much to a contract catering firm losing a hospital account to a competitor, a law firm's back-office function being outsourced, or one company simply buying another as a going concern. If you're a line manager, HR business partner, or operations lead involved in any of these situations, you need to know the basics — alongside the wider context of what's changing for employers under the Employment Rights Act 2025, which is reshaping several adjacent areas of day-to-day people management at the same time.

When TUPE Applies

TUPE is triggered in two broad scenarios. The first is a "business transfer" — where a business, or an identifiable part of one, changes ownership and continues to operate in substantially the same way under the new owner. The second, which catches many managers off guard, is a "service provision change" — when a contract to provide a service moves from one provider to another (outsourcing), comes back in-house (insourcing), or moves between contractors at re-tender. In all of these cases, the employees who were "assigned" to that business or that contract immediately before the change are the ones TUPE protects.

What "Automatic Transfer" Actually Means

The core mechanic of TUPE is simple to state and easy to get wrong in practice: affected employees' contracts of employment transfer automatically to the new employer on their existing terms and conditions. Continuity of service is preserved, meaning length of service carries over for things like redundancy calculations and statutory notice. The new employer effectively steps into the old employer's shoes as if the contract had always been with them. Managers sometimes assume a transfer is a natural point to "reset" terms, harmonise pay structures, or quietly renegotiate — it isn't, at least not immediately, and attempts to do so purely because of the transfer are usually void even if the employee appears to agree to them at the time.

Information and Consultation Obligations

Both the outgoing employer (the transferor) and the incoming employer (the transferee) have duties before a transfer takes place. The transferor must provide "employee liability information" to the transferee — details of who is transferring, their terms, any disciplinary or grievance history, and any collective agreements that apply. Both employers must inform, and where measures are envisaged, consult with appropriate representatives of the affected employees — either existing trade union or employee representatives, or ones elected for the purpose. This isn't a box-ticking formality: getting the timing and content of information and consultation wrong is one of the most frequently litigated aspects of TUPE, and failures can lead to compensation awards.

Dismissal Because of the Transfer

Dismissing someone because of the transfer itself — rather than for an unrelated reason — is generally automatically unfair. The one recognised exception is where there's a genuine "economic, technical or organisational" (ETO) reason entailing changes in the workforce, such as a genuine redundancy situation caused by duplicated roles after a merger. Even then, the usual fair process for redundancy or dismissal still has to be followed; the ETO reason doesn't remove the need for a fair procedure, it simply provides a potential defence to the "automatically unfair because of the transfer" rule.

Common Pitfalls for Managers

A few mistakes come up repeatedly in practice. The first is informal side-deals — a manager telling a transferring employee "don't worry, we'll sort your terms out properly once you're settled in" often creates confusion and, if it involves any detriment compared to their transferred terms, legal risk. The second is treating a service provision change as if it were a simple recruitment exercise, interviewing transferring staff for "their own job" as though the role were newly vacant — TUPE doesn't work that way, and the role and the person are presumed to move together. The third is poor record-keeping: not identifying clearly which employees were actually "assigned" to the transferring business or contract, which matters enormously when a workforce splits across multiple contracts or sites.

Practical Steps for Managers

If you're managing people through a transfer, a few habits go a long way. Get employee liability information early and check it against what you observe on the ground — job titles and formal records don't always match who's actually doing the work. Keep communication with affected staff clear, consistent, and jointly agreed between outgoing and incoming employers, rather than each side giving a different account. Don't make promises about future changes to terms until you understand what's actually permitted, and involve HR or legal advice before agreeing anything that varies a transferring employee's contract. And remember that TUPE due diligence isn't only a legal exercise — it's also where people first form an impression of what the new employer will be like to work for.

Frequently Asked Questions

Does TUPE apply to small businesses as well as large ones?

Yes. TUPE applies regardless of the size of the business or the number of employees affected — a transfer involving two employees is covered in principle just as much as one involving two hundred. Smaller employers are still expected to meet the information and consultation duties, though the practicalities of who represents the workforce may look different without a recognised trade union.

Can employees refuse to transfer?

An employee can object to the transfer, in which case their employment with the old employer ends, but they aren't automatically treated as dismissed and generally can't claim unfair dismissal or redundancy on that basis alone, unless the transfer would involve a substantial and detrimental change in their working conditions.

Can terms and conditions ever be changed after a TUPE transfer?

Sometimes, but the transfer itself can't be the reason. Genuine changes agreed for reasons entirely unconnected to the transfer, or permitted under the ETO exception with a proper process, may be possible — this is an area where getting specific legal advice matters, because the rules are more restrictive than many managers expect.

Who is responsible for a transferring employee's past conduct issues?

Broadly, liability for things that happened before the transfer — including employment tribunal claims relating to the period before the change — passes to the new employer along with the employee, which is exactly why accurate employee liability information matters so much during due diligence.

TUPE situations move fast and the legal detail is easy to get wrong under time pressure. Building a working understanding of the framework — rather than relying on assumptions from ordinary recruitment or restructuring — is one of the most practical things a manager involved in a transfer or outsourcing decision can do. Learnsignal's workplace compliance CPD courses cover TUPE and related employment law topics for managers who need a solid, practical grounding without wading through the regulations themselves.
