Great product from great company
I don't usually provide gushy feedback but in this case it is warranted. Great product from very professional company. Structurally bonded as opposed to DIY assembly by majority of competitors. Gavin took the time to work with me through number of alternatives before selecting most appropriate solution. Improved delivery lead time and arrived when agreed. Looks fabulous in situ and many people have commented how good it looks. I could not recommend more highly.

The whole process was very easy, I ordered online with my builders measurements but duplus answered all question I had. Once ordered had no problems and my roof lantern was delivered on time with them phoning the day before to arrange delivery. Would recommend and use again.

Duplus - great lanterns and great supporting service…
Duplus provide a very good supporting service from the time of initial contact through the tooing and froing of quoting and exact sizing of in my case two lanterns (1200mm x 2400mm). Both Amar and Gavin provided a nothing is too much trouble support. Delivery was on the date as arranged.
The lanterns themselves look excellent - I really like the limited frame and the low (30degrees) profile. They have only been a few weeks and in generally good weather, but I am looking forward to the light and sky views these will give me over the coming years. I'll post some photos in due course.
