Summary

  • That is not a minor administrative mismatch. It is the point at which a simple retail promise becomes an infrastructure handoff. One provider has begun supplying service; another must stop service and rental liability; an industry message joins the two events. If those records do not agree, the customer carries the cost of proving what occurred.

  • Ofcom’s current guidance makes the gaining provider the organiser of a residential One Touch Switch. The customer supplies the address, the old provider and the services to be moved. The losing provider then sends information about consequences such as charges and bundled services. Once the new service works, the old service should cease automatically.

The economic test is the handoff

The commercial incentive is clear. The new provider is paid to activate quickly. The old provider needs a reliable instruction before closing service and billing. The household wants continuity without double payment. A working router proves only one of those outcomes.

The TOTSCo message specification supplies a sharper boundary. After the gaining provider completes provision, it sends a switch trigger containing a switch-order reference and an activation date. That date tells the losing provider when billing should stop. The trigger is therefore more than a technical acknowledgement: it is the bridge between service state and rental liability.

This does not prove that every provider processes every message correctly. Ofcom closed its industry-wide implementation enforcement programme in June 2026, but that is not a certificate for each individual switch. Nor does the specification prove a customer’s account was reconciled. It defines what should be connected; the bills show whether the connection survived operational reality.
