Guarantee & Insurance Detail - About Us

JMI is a registered member of FENSA (Reg. No. 12685) and amongst other building regulations FENSA stipulates that all customers must be offered insurance that covers their replacement window and door installation in the event of the company ceasing to trade. Unfortunately the industry has a history of both small and large companies becoming insolvent, leaving customers with worthless guarantees and costly expense when any rectification work has to be carried out. This new regulation has been put into force to help protect consumers if this happens. JMI also, in addition,  insure deposits taken upon order, for customers added peace of mind.
Most of our windows are ‘A’ rated and will carry an Energy Label. Not all products are applicable for an energy rating or cannot attain an ‘A’ rating, please check at time of purchase.
