I'm about to have my central heating system completely replaced, including the pipe work. I have my £300 warmfront rebate voucher, the installer I have chosen is not one of their registered installers, but I understand all they need to do is go online to register. My chosen installer did say that warmfront isn't all it's cracked up to be and that they wouldn't receive the full £300 rebate after having deducted it from my bill. Is this so? Also, I'm wondering if the heating companies on this register quote a higher price to begin with. I've had 7 different quotes... British Gas £5600 (wow) out to lunch, obviously didn't chose them .
