EOS were chosen as the rooflight supplier as our builder had failed to deliver the items. Rooflights were 1500mm square, something other suppliers were unable to provide. Rooflights were delivered and fitted on a Saturday morning two weeks before Christmas. They dropped onto the prepared upstands. Great service from start to finish, they knew exactly what they were talking about, the manufacturing is first class, they were local. Would we recommend them to anybody who wanted a first class product. without a doubt.

We have had several eos rooflights (possible 10-12) over the last 5-6 years. Every one has been as it should be. Received in perfect condition, delivered on time. And the roof-lights are well made and look perfect once fitted. Company is also very helpful if help is required. I’ve seen cheaper alternatives supplied and fitted by others but they are inferior quality. These are

Recently purchased an electric roof light from EOS. Very happy with the finished product, study and functions very well. It also looks very stylish. I received excellent customer service from EOS at all stages, they couldn't have been more helpful. Highly recommended.

EOS Rooflights were knowledgable in their field, very helpful and the products (Roof Lantern and Flat glass roof lights) were of a good quality. The Roof lights were easily installed and full installation instructions were supplied for those who are installing for the first time. Would recommend.

Very efficient with processing my order and delivery. I ordered a 3M roof lantern and a smaller flat roof light. Both were simple to install on my own upstands and they both look great. My only negative was the cost was a lot for what they are but I don’t think eos are excessively expensive, I think the roof lanterns themselves are what’s pricey. Anyhow I’m happy 😃

EOS were brilliant all through the consultation/sales process and delivery. The skylight looks great and works a treat with the electronic switch. Their after-care support was also very helpful and patient when we mistakenly thought we had an issue. Would highly recommend them.

As a company we have used EOS for some time. We use the EOS Rooflight Flexi Lid product a lot and also the EOS Smoke Vent Rooflight AOV on our projects. We cannot fault the company for the service, communication and value for money.

Excellent products, great customer service and post sales support! Unfortunately the courier damaged our roof lights slightly, however EOS went above and beyond to rectify! Special mention to Natalie O’Hara in ops, she was so helpful, prompt and a real pleasure to deal with! Highly recommend EOS!

My Eos rooflight turned up on time as always, simple to install and looks great, throws so much light into what was a dark space, the quality of the rooflight is amazing, I will continue buying from Eos in the future,

The rooflights are a key feature externally of the property as they are prominent on the flat roof. They are angled by 15 degrees to allow the south facing sun to enter the house maximising natural light and also utilising any solar gain. The majority are triple glazed, with a couple of larger opening lights being double glazed. Internally they provide so much light and the light shafts are a characteristic of the internal architecture given that there are 15 within the house. The ordering and supply process was straightforward and installing them worked well with the pre-made upstands. All in all a very satisfactory and successful decision to select Eos rooflights.

I was after rooflights with laminated glass and of good quality! I contacted EOS after seeing and viewing their products. They fitted the requirements. The service was first rate, nothing was a problem and the drawings to work before delivery excellent. Would highly recommend.
