Absolutely shocking experience Absolutely shocking experience. The company is great at sales and letting you know they install. What they don't tell you is the vast majority of the installers are independent from Wren. Wren have absolutely no control over the installers nor do Wren see it as their business to address any installations issues as a priority because and I quote, "installers are independent. You can get a quicker response by contacting them direct." Which is a quote I heard numerous times. Wren will also quote they project manage the installation. Which to be fair they will - they'll manage the main installation. After that any issues or things you want addressing after the main installation are Wren's lowest priority. I would not recommend due to after sales experience and the absolute nightmare I've had to get them to address post installation issues. I took time off of work on more than 3 occasions since the installation to wait in on a Wren promise that someone was coming. Only for no one to show up at my home. They've also sent the wrong product on 2 separate occasions to address issues I had meaning more delays, more missed appointments and more arguments to get them to address the issues! Shocking!
