I found the workers at Sunboost to be pushy when it came to paying. Of course the customer needs to pay, however being asked to pay before job is completed is not usual. Than to be phoned several times on day of installation before job is done asking for payment was very annoying. The installers drilled right through into my dinning room and after several phone calls they did half a repair job. No hope they will complete the repair? Paid in full on day of install, then found out inverter was faulty. It took almost two weeks to get a replacement. Call centre staff were polite, but I felt I was been given the run around. Glad now all seems to be working, hopefully it stays that way.
