Confusion around the terms commissioner, buyer, service user, customer (as used in the TEC sector) can arise because (eg) a local authority is a buyer in some transactions, a commissioner in others, and a provider in still others.

Need to establish a terminology that clearly identifies roles within the TEC sector:
- Commissioner of services (eg LA)
- Buyer of services (eg a residential home)
- Equipment supplier
- Telecomms provider
- Service provider - assessment
- Service provider - installation and maintenance
- Service provider - monitoring
- Service provider - response
