M&A advisory: TUPE and integration.
The deal is agreed. This is the work that decides whether it delivers.
Scope
TUPE on share and asset deals and service provision changes; employee liability information; measures and consultation; harmonisation. Post-close: Day 1 readiness, org design across the combined business, terms and comp harmonisation, retention.
Deliverable
A sequenced plan with the legal constraints built into it rather than bolted on: consultation timetable, measures position, Day 1 pack, structure, and the harmonisation route with dates and a basis.
Timeline
Engaged pre-completion wherever possible. Consultation obligations set the critical path, and they take weeks that integration timetables rarely carry.
Fee basis
Fixed fee for the planning phase; delivery scoped separately as a defined project or a retained arrangement through the first hundred days.
The argument
Most businesses treat TUPE as an HR process. That is why the liability gets priced into the deal at their expense. The commercial team negotiates the transaction, the lawyers draft the agreements and the indemnities, and the transfer itself is handed to HR as a compliance exercise: consult the employees, produce the liability information, hold the meetings, manage the correspondence. By the time anyone in the deal team looks at it again, the measures have been agreed, the harmonisation route has been foreclosed, and the allocation of employment liability between the parties has been settled by the people with the least involvement in the negotiation.
The compliance obligations are the floor. The commercial content sits in what gets negotiated around them: which liabilities transfer and which are indemnified, what measures the transferee declares and what it therefore commits to, and whether the harmonisation the synergy case assumes has a lawful route to it or merely an intention. That negotiation belongs with the people running the deal.
TUPE: share deals, asset deals, and service provision changes
Establishing whether, and when, there is a transfer
On a share deal there is no relevant transfer at completion, and acquirers frequently stop the analysis there. The transfer arrives later, when the acquired entity's employees are migrated into the buyer's, when a function moves into a shared service centre, or when an activity is insourced. On an asset deal or a business transfer, TUPE usually applies from the outset. A service provision change catches the outsourcing, insourcing or retendering that a large proportion of synergy plans depend on. Getting this mapped before the integration plan is drafted is the difference between a plan that can be executed and one that has to be rewritten.
Employee liability information as planning material
The regulations require the transferor to provide specified information not less than 28 days before the transfer. Treated as a compliance box, it arrives late and thin. Treated as what it actually is, which is the only complete picture of the population the transferee is about to become responsible for, it is the input to every subsequent decision: who is in scope, what they are contractually owed, what disciplinary and grievance history is coming across, and what is already in dispute. We specify what to ask for, and press for it at the point the transferor still wants the deal.
Measures and consultation with representatives
The measures a transferee envisages have to be notified to the transferor so that the transferor can consult on them, which means the transferee has to know its own intentions earlier than integration planning usually delivers them. Where there is no recognised union or existing body, representatives must be elected, and that election has a timetable of its own. A protective award runs to thirteen weeks' pay per affected employee and is punitive rather than compensatory, so it does not reduce because nobody suffered loss. Consultation is the critical path, and it is the item most often discovered to be so after the completion date has been fixed.
Post-transfer harmonisation and its limits
A variation of terms is void where the sole or principal reason is the transfer, and that restriction does not lapse with time. The synergy case that assumes the acquired population will be moved onto the acquirer's terms in year one is, in most cases, assuming something the regulations do not permit in the way it is intended. There are routes: a reason unconnected with the transfer, an economic, technical or organisational reason entailing changes in the workforce, a properly constructed collective process, or the passage of time and events that genuinely break the causal link. Each has conditions and each has a sequence. Designing the harmonisation around those constraints from the start costs a fraction of retrofitting it afterwards.
Post-close integration
Day 1 readiness
What the acquired organisation is told, by whom, in what order, and on what day. Employees form a settled view of what the deal means for them within the first week and revise it slowly afterwards, which makes Day 1 the cheapest and most durable intervention available. The pack covers the announcement sequence, the questions management will be asked and the answers they are authorised to give, the practical continuity items that signal competence or its absence, and the population that needs an individual conversation before the general one.
Org design across the combined business
Every acquisition contains an implicit answer to which operating model the combined business runs on. A bolt-on to a platform absorbs into the platform. A merger of equals in substance, whatever it is called in the announcement, needs a design rather than an absorption. A carve-out has to build capability the parent used to supply. Making that implicit answer explicit, testing it against the deal rationale, and designing spans, layers and decision rights accordingly is what separates integrations that capture synergies from integrations that model them.
Terms and compensation harmonisation
Two populations doing the same work on different terms is a durable cost and a durable grievance, and the longer it runs the more expensive it becomes to resolve. The harmonisation programme sets out what is being aligned, on what basis, in what sequence, and what is deliberately being left alone, with the TUPE constraints and the commercial priorities reconciled in a single plan rather than negotiated against each other by two functions that are not talking.
Retention of the people the deal was priced on
Uncertainty about who is in, who is out, and who is in a changed role has a direct and fast effect on retention, and every week the question stays open is a week in which the most mobile people in both businesses are taking calls. Speed matters; sequence matters more, because population decisions made before the structure is designed produce a structure retrofitted to the people who happened to stay. The retention design needs a commercial element and a clarity-of-role element, and the second is usually the more effective lever and the one most integration plans leave out.
From the casebook
The acquired business was losing its practitioners because the integration had not protected what made it worth acquiring
A PE-backed professional services acquirer had completed a bolt-on eighteen months before they came to us, and the integration had stalled in a way that was beginning to show in the numbers. Practitioner attrition in the acquired entity was running above the modelled rate, client retention in that part of the business had softened, and the integration metrics the board had been tracking had stopped improving.
The cause was a parallel authority structure that had grown up during the integration. The acquirer's centralised management model, with standardised reporting lines and group-level decision authority, had been applied to a business that ran on origination-based economics and high practitioner autonomy. The acquired practitioners were accountable for revenue without the operating environment that had underpinned their ability to generate it. The most experienced of them had begun to leave.
We designed a protected operating environment for the acquired entity with a defined 36-month convergence pathway, specifying which elements of the acquirer's model would be introduced and when, and which would not be imposed at all. Accountability frameworks were rebuilt so that authority matched the revenue obligations placed on practitioners, and the compensation structure was adjusted to reflect the origination economics rather than overwriting them with the group's standard model.
Attrition returned to pre-acquisition levels within a quarter. The integration metrics resumed their improvement, and the board had a documented rationale for the governance differences that satisfied both the portfolio company's audit requirements and investor scrutiny.
How we engage
The work is most valuable pre-completion, running in parallel with the legal and financial close rather than starting the week after it. By completion the employee liability picture is fixed, the consultation window has either been used or lost, and the acquired organisation has been forming its own view of the deal for several weeks without anyone shaping it. Even a two-week pre-completion phase changes what is available. Where the engagement starts post-close, and it frequently does, the first task is establishing which decisions are still open.
The practice works alongside in-house integration teams rather than replacing them: providing the structural and TUPE expertise the team does not hold, taking the workstreams where external independence carries weight, and giving the board or the sponsor a senior read on progress that is separate from the integration team's own reporting. Employment counsel, where litigation risk or a novel point requires it, is drawn from an established network on a defined-scope basis.

About Sam and the firm →Frequently asked questions
- When does TUPE apply on a share deal?
- It does not apply to the transaction itself. On a share acquisition the employing entity does not change, so contracts continue unaffected and there is no relevant transfer. TUPE applies to what happens next: the migration of employees from the acquired entity into the acquirer's, the movement of a function into a shared service centre, the insourcing or outsourcing of an activity as part of the integration. Acquirers who conclude that TUPE is irrelevant because the deal is a share deal typically discover otherwise around month four, at the point the integration plan is already committed.
- What is a service provision change and why does it matter here?
- A service provision change is the second limb of TUPE: activities carried out by one provider transfer to another, or come back in-house, and the employees principally assigned to them transfer with the work. It catches outsourcing, insourcing, and the retendering of a contract. It matters in integration because a large proportion of synergy plans involve moving an activity, and moving an activity moves people, their terms, and their liabilities with it. A synergy case built on headcount reduction in an activity that is about to transfer is a case built on a dismissal that will be automatically unfair.
- What is employee liability information and when is it due?
- The transferor must provide the transferee with specified information about the transferring employees: identity, age, particulars of employment, disciplinary and grievance records from the preceding two years, legal actions in the preceding two years, and any collective agreements. It is due not less than 28 days before the transfer. It is routinely provided late, incompletely, or in a format that makes it useless for planning, and the transferee routinely accepts this because the commercial relationship is new. The information is also the raw material for every integration decision that follows, so accepting it late is a decision to plan the integration without it.
- Can terms be harmonised after a TUPE transfer?
- Not by reason of the transfer, and that constraint has no expiry date. A variation is void where the sole or principal reason is the transfer itself, regardless of whether the employee agreed to it and regardless of how much time has passed. Harmonisation is achievable, but it has to be built on a reason that is genuinely independent of the transfer, or on an economic, technical or organisational reason entailing changes in the workforce, and it has to be sequenced accordingly. Acquirers who draft the integration plan first and take the TUPE advice second end up either redrafting the plan or proceeding on a basis that will not survive challenge.
- Who should be consulting, and with whom?
- Both transferor and transferee have obligations, and they are not the same. The transferor must inform and consult appropriate representatives of its affected employees about the transfer, its timing, its reasons, and the measures envisaged. The transferee must tell the transferor about measures it envisages taking, so that the transferor can consult on them. Where there is no recognised union and no existing body, representatives have to be elected, and that election takes time that integration timetables rarely allow for. A protective award of up to thirteen weeks' pay per affected employee is the price of getting this wrong, and it is uncapped by any reference to loss.
- How does the integration work relate to the diligence?
- Directly, where we have done both. The diligence establishes what the acquirer is buying and what it will cost to keep; the integration is where those findings are either acted on or quietly abandoned in the pressure of the first hundred days. Where the diligence was done elsewhere or not at all, the engagement starts with a compressed version of it, because an integration designed without a view of who actually matters in the acquired business is a sequence of activity rather than a plan.
