I ordered a roof lantern from Duplus for our new kitchen room and I am absolutely delighted with it. Gavin and the team were just lovely to deal with, from the initial telephone inquiry up to and including the delivery, always polite, professional and extremely helpful. They answered all the queries my builder had so he could build the kerb for the lantern and when it arrived the installation was very straightforward. They were also very accommodating regarding the delivery date - the lantern was ready on the expected date and delivery was arranged as soon as we were ready to install it.
I highly recommend both Duplus and their lovely lantern!
A delighted customer!

Very good
Product seem good, a bit too early to tell, and it turned up on time, they gave me a scare when I called to enquire about delivery as they were a bit vague, but in the end all was good so on balance I'd give them a thumbs up and recommend them

A pleasure to deal with from start to finish!
Gavin was a pleasure to deal with, the roof light arrived earlier than the time frame given and the product was described perfectly and suits our needs very well indeed. I wouldn't hesitate in recommending Duplus to anyone looking for roof lights and/or skylights.

My experience with Duplus from start to finish was excellent. Gavin is so helpful and provided me with all the information that I needed. My roof light is truly amazing - it is chic and elegant and it has definitely provided the "wow' factor that I was looking for. Don't look any further - Duplus are great!
