Not even worth one star, I moved in 2018 house has been so cold both avant and NHBC have ignored the seriousness of the issues where they came out inspected all windows with a credit card and with findings draft coming into the house via windows , this is an area manager of NHBC class as technical . After 5 years of fighting them both With no outcome and no suggestions, I had a thermal image report By accreditation technical manger in this field in my favour , presenting this to them , they both refused to accept . I have sent an email that I will now be taking them to court. And basically laughed in my face via email. They think as they have a retainer and millions they can get away with it and because we are the little people we let these rip off merchants get away with, well I have now threatened them my proposal of legal actions against Avant homes email sent to all directors . I will no bow down to them and feel that they can beat me due the their bank account . This report is binding and will stand in court and will be in my favour. Avant know this but they assume money will drain me and give up. Avant will do every thing in their power to find loopholes for me to,loose. But they have messed with the wrong person, and they know this as I have fought tooth and nail ,on other issues I have won. I have a good legal team who have found legal loopholes to bring them down as over the years it was impossible as client were drained from legal,fees but things have changed I’m looking forward to bringing down Jeff Fairburn and his team of directors
