    Delighted Customer 20/05/2014 17:52:06

    My first time using this company and could not believe the reviews. Ordered some twinwall in order to check against my greenhouse, unfortunately the courier let them down and it took 5 days to arrive. But Greenhouse Warehouse kept me informed and apologised. Made further order which arrived with 48 hours, including a Sunday evening. I now agree with the reviews and would always return to Greenhouse Warehouse for new purchases.

    Very impressed by the courtesy on the telephone and the user friendly website. Order sheets before 2 p.m and they were delivered very well packed the following day. Can't wait to fit them to my greenhouse which has been lacking five sheets of glass for over a year. What a great product to replace broken glass. Will definitely use again....and again. Thanks
