St Helens is served by SP Energy Networks, the electricity network operator for North Wales, Merseyside and Cheshire. A heat pump has to be registered with the network operator. Your installer normally does this: smaller systems are notified after installation, and larger ones need approval before work starts. St Helens is close to the edge of the North Wales, Merseyside and Cheshire area, so some homes may be on a neighbouring network.
