The hidden cost of interest-free

Our solar installer offered 28Watt’s services when we received our quote. I knew we wanted to pay with finance but wasn’t sure what the cheapest option was. Within minutes I could see Westpac, ING, and RACQ green-loan options side-by-side no extra paperwork. We picked the lowest rate and booked the install the same day.

The plumber replacing our old gas hot-water tank used 28Watt’s portal to pre-qualify us for Community First Bank’s eco-loan. The approval arrived before the new heat-pump was out of the box, and the repayments are less than our energy bill savings.

A battery felt out of reach until the installer showed 28Watt’s financing options. Seeing exactly how much each lender would cost and the projected bill savings gave me the confidence to lock it in. I chose RACQ’s 6.99% green loan and cut the pay-back period by two years.
