I did not know who to contact
I did not know who to contact , and rang AB Energy to see if they could help. I made an appointment for their engineer to visit. The representative (Andy) turned up exactly when promised. He spent time listening to me outline the issue, and then he started testing the system. He explained to me what he was doing and why. He quickly identified what was needed and then did the repair. He then checked the rest of the installation, again explaining as he went. I learned a lot from him.
