Had to call them out twice within 6 weeks of front door installation. Got locked in my house for hours as the door would not open so had to take leave from work. The guy that came out eventually got door open then pointed out flaws with the installation. The door is now sticking. Complained to customer services but got fobbed off, refused compensation and told if the door lock fails out of their office hours it's down to me to pay for a locksmith, not their problem. They are coming out for a third time to hopefully to rectify the faults on this installation. As I paid thousands for this I would expect top quality workmanship and customer service but I got the opposite. Would never use them again
