When a cleaning contract changes supplier, the team usually transfers with it. That is not a technicality to be resolved after the award. It shapes the price, the timetable and the risk profile of the whole contract.
Employee liability information has to be requested early. It covers terms, continuity of employment, and any recorded grievances or claims. A supplier who prices without it is either guessing or planning to find the difference later, and both outcomes land on the client.
Measures letters matter more than they are usually given credit for. Transferred staff who understand what is changing, and when, arrive on day one able to work. Staff who discover it on the day arrive ready to leave, and the service dips in exactly the period the client is being asked to justify the change.
Induction is where the new supplier either earns the transfer or loses it. Chemicals, equipment, site rules, escalation routes and the audit standard should all be covered before the first shift under the new name. We treat induction as part of mobilisation, not an administrative afterthought.
For procurement, the sensible approach is to make TUPE a scored section rather than a yes or no question. Ask for the transfer timetable, the consultation approach and an example induction plan. The answers tell you more about the supplier than the rate does.
