Most HR teams understand that when you acquire a business or take on staff under TUPE, you inherit their terms and conditions. What often gets missed is that employee benefits are not just a payroll issue or a nice‑to‑have add‑on. They are a web of contracts, disclosures, insurer assumptions and eligibility rules. If those are wrong or incomplete, the consequences can be very real.
We recently saw this play out in the worst possible way. A business acquired another company but did not disclose the full picture of who was transferring and what benefits applied. When an employee later passed away, the insurer declined the claim. Their position was simple. They were never told about the acquisition, the additional staff or the risk factors. The policy had not been updated and the cover, in their view, did not apply.
No one sets out to create that situation. But it is a useful reminder that TUPE is not just an employment law exercise. It is a benefits risk exercise too.
Benefits sit in the blind spot of many acquisitions
During an acquisition, attention naturally goes to the headline issues. Legal structure. Headcount numbers. Pensions. Payroll. Benefits often sit somewhere in the middle, especially if they are seen as legacy or low‑cost.
That is where problems creep in.
Employee benefits rely on accurate data and clear communication with providers. Insurers price and underwrite based on what they are told. Eligibility rules matter, waiting periods matter, material facts matter. When a group of people quietly moves from one employer to another, those assumptions can break.
TUPE does not override insurance contracts. It does not automatically update a group life policy. It does not force an insurer to pay a claim if the policy terms have not been met.
HR teams are often the last to find this out.
The risk is not theoretical
When benefits are not properly reviewed during an acquisition or TUPE transfer, several things can go wrong.
Employees may believe they are covered when they are not. Policies may technically exist but be invalid because the insurer was not informed of a material change.
In the most serious cases, this only comes to light when a claim is made. At that point, there is very little room to maneuver. If the information was wrong or missing, the employer carries the risk.
This is uncomfortable territory for HR. It quickly becomes a governance issue, not a benefits query.
What HR should be checking when TUPE is involved
When acquiring a business or taking on TUPE staff, HR should be asking some very specific questions.
- Which benefits are contractual and transferring under TUPE, not just offered in practice.
- Are you notifying the existing provider of a change or moving them to a new provider.
- Are there any material facts an insurer will want to know.
- Whether the insurer has formally acknowledged the change in employer or headcount.
None of this is glamorous. All of it matters.
Why “we’ll harmonise later” can be dangerous
A common approach is to leave benefits as they are post‑transfer, with a view to harmonising later. That can be sensible from an employee relations perspective. But it still requires immediate housekeeping.
Leaving benefits untouched does not mean leaving insurers uninformed. It does not mean ignoring data mismatches. It does not mean assuming cover continues as before.
If anything, the period before harmonisation is where risk is highest. You have complexity, legacy arrangements and limited visibility. That is exactly when things slip.
A useful way to frame this internally
For HR leaders needing to get traction with finance or leadership, it can help to reframe the conversation.
This is not about being overly cautious. It is about unmanaged liability.
Employee benefits, particularly insured benefits like life assurance and income protection, transfer financial risk from the employer to the insurer. That transfer only works if the insurer has the right information. If they do not, the risk snaps back to the employer at the worst possible moment.
That is a framing most boards understand.
In summary
TUPE is often described as protecting employees and in many ways it does. But it does not protect employers from the consequences of poor benefits governance.
Acquisitions and TUPE transfers are disruptive by nature and things get missed. The uncomfortable truth is that benefits only get attention when something goes wrong.
The aim is not perfection. It is awareness. Treat benefits like live contracts during TUPE, not background noise, and you reduce the chance of learning a hard lesson when it is already too late.
