More guarantees, more IBGs, more certification - once again the window and door industry in England and Wales is undergoing major changes in regulations on standards and guarantees. The bad news is that it will place very window installer under a whole new raft of legal obligations. The good news is that more and tighter regulations means the cowboy traders are more and more isolated, giving the honest professionals more chance than ever to prove their integrity to the consumer. The biggest change is that it will now be mandatory for every Competent Person Scheme member to give each customer financial protection on every installation. It is no longer an option simply to offer an IBG - every homeowner must be given one for every installation. The changes also see new rules regarding the MTC (Minimum Technical Competence) Card, verifying the holder's abilities in domestic window and door installation and surveying. These changes mean there must be at least one cardholder present at every installation and, with some exceptions, every survey must be carried out by a cardholder.
