Beware of these scammers. They will sell the stuff then worst customer service starts. I call them scammers because they offer you a very attractive incentive. They say “if you bring 4 customers your panels are fully pai off” which is trapping more customers through an existing customer who is already trapped is a £10k debt. Their customer service sucks as they keep telling you that we have a written contract so you are bound to live with it. Can’t say anything good about them because I can’t think of one. In my case the initial survey was wrong. The brilliant agent worked out 12 panels can be fitted on the roof. When fitters came they couldn’t fit more than 5 panels. Rest is the bad experience. Their way of customer service proving you in wrong because you have signed a contract. If they call or knock at your door, just slam the door shut. It’s not worth wasting your time listening to their garbage.
