You’re not wrong, I had to pay the installer 100% of the price of the Hilo at the time of order. Simply because they did not want to carry the risk themselves. Leaves you well and truly up the creek if that installer goes to the wall having not passed that money on to Hilo, or if Hilo bins them as an installer before you get your roof.I had to pay 75% bacs transfer for my HiLo roof, it does leave you a little exposed to say the least.
