I think commission must be made for the sales reps through the finance plans which have a hefty interest rate of 19%apr!!!! However, go through finance and you get your windows for more than 50% less. We were advised that a composite front door retailed at £5000. I just cannot believe this pricing and the pressure to take out a finance agreement which believe it or not can last for 10years. 10 years at 19%, well that’s an awful lot of wasted money. It’s a shame that they’ve gone down this shady selling route as their products are good. Will definitely not be using them nor recommend anyone else does unless of course, you’ve won the lottery
