Why we think this

Under threat because Solar Directory archived its listing on 16 September 2025 because its website stopped working. Still trading signs: ABN 90481672464 (THE TRUSTEE FOR ENTERPRISE POWER UNIT TRUST) is still active. Only its website has gone. Check Google, the phone number and the ABN before treating it as closed.

The date comes from: Last SolarQuotes review (last seen trading).

One sign of trouble (a cancelled name or ABN, a dead website, a run of one star reviews) but not enough to call it closed.

Installer gone? We look after orphaned systems.

If the company that put in your solar or battery has closed, we can check the system, chase the manufacturer's warranty and keep it running.
