We used ultimate 9 years ago. We were very disappointed. Would not recommend them. Had to replace windows few years later.

I used ultimate windows in 2003 to fit a bespoke conservatory in my old home. They helped with all permitted development planning and the work was done to an exceptional standard they even helped locate special strips to go inside the conservatory roof to save on heat loss and to prevent over heating in summer. I have now moved to a new home and wanted an orangery with pelmet and down lights. I called many companies but once again used ultimate as they were very professional when we told them our requirements. They even helped save money on getting an architect to drawn the plans as we required
