TUPE: Protecting Employees When Your UK Business Is Acquired
TUPE transfers move employees with the business they work in. Most M&A teams underestimate the consultation timeline. Here's the operating playbook for UK transfers in 2026.
The Transfer of Undertakings (Protection of Employment) Regulations 2006 — TUPE — implement the EU Acquired Rights Directive in UK law (and continue to apply post-Brexit in modified form). The mechanic is straightforward: when a business or service is transferred, the employees attached to it transfer too, on their existing terms, with continuity of employment preserved.
What counts as a TUPE transfer
Two types:
- Business transfer — sale, transfer, or merger of an economic entity that retains its identity post-transfer (a recognisable going concern, not just an asset sale of disparate items)
- Service provision change — outsourcing, insourcing, or change of contractor for a service, where the same activities continue to be performed and the workforce remains "an organised grouping of employees" assigned to those activities
The UK government's TUPE guidance is the standard reference. The Acas TUPE guidance is the more practitioner-oriented companion.
The four employer obligations
- Inform. Both transferor and transferee must inform appropriate representatives of affected employees of the fact, timing, reasons, and legal/economic/social implications of the transfer
- Consult. Where the transferor or transferee envisages measures (changes to terms, redundancies, reorganisation), consultation with representatives must take place with a view to seeking agreement
- Provide Employee Liability Information (ELI). The transferor must provide the transferee with prescribed employee information at least 28 days before the transfer
- Preserve terms. Post-transfer, the transferee inherits employment contracts on their existing terms with continuous service
Where consultation timelines bite
"Long enough before the transfer to enable consultation" is the statutory phrase. There is no statutory minimum, but the case law has gravitated toward 30 days for straightforward transfers and longer where measures are envisaged. Tribunals award up to 13 weeks' pay per affected employee for breach of the information and consultation obligations — a material cash exposure on transactions involving large workforces.
Post-transfer changes to terms
Regulation 4(4) prohibits changes to employment terms where the sole or principal reason is the transfer. Three permitted variation paths:
- The contract itself permits the variation (rare for material terms)
- The variation is for an "economic, technical, or organisational reason entailing changes in the workforce" (ETO)
- The terms are derived from a collective agreement that has been varied since the transfer (with limits)
Harmonisation of acquired-employee terms with the transferee's existing workforce is famously difficult — the bare desire for harmonisation is not an ETO reason.
The Brexit drift
Post-Brexit, TUPE remains in force largely unchanged. The 2023 Retained EU Employment Law Consultation explored simplifications for smaller businesses; the substantive transfer protections remain intact in 2026. For broader UK employment context, see our TUPE glossary entry.
