Support Options
Typical Response Time
Our Core — Tech Support
Support First.
Installers When You Need Them.
We're former GivEnergy product specialists — the people the support desk turned to when they were stuck. Most issues we can diagnose and resolve remotely, or arrange a fast on-site repair. That's where we start with every customer.
When a fix needs new hardware or a full install, we hand you to our reviewed installer network — compare proposals from trusted local engineers and choose the one that suits you. One conversation, from fault to finished job.
Diagnose
Raise a ticket or call us. We triage the fault and diagnose it remotely — most issues don't need a visit.
Resolve
We fix what we can remotely, or book a fast on-site repair from our specialist team.
Connect
Need hardware or a full install? We hand you to our reviewed installer network to compare proposals and get it done.
