Thank you so much for the exceptional service I received... From order to delivery (the very next morning) I couldn't recommend these guys highly enough... Brilliant

Good quality product, reliable service & hassle free installation.

We have used Duplus before and are very happy with the quality of the windows produced. Duplus are a great company. All previous purchases have been standard sizes and delivered very quickly. This order was for a non-standard size and was estimated delivery at 6 weeks. I contacted Duplus direct and asked if they could delivery earlier and they tried very hard to be accommodating. While they did manage to deliver the window in 5 weeks for which our customer was very grateful for, the communication about production and delivery could have been better. Some delays were not communicated and caused issues with our customer I would have absolutely no issue in recommending Duplus to other customers

Quick delivery, efficient service and the company updated us regularly about when the item would be delivered.

100% happy, service and delivery was just great. Nothing was too much trouble, delivery driver even called when he was 30 mins away, so we could take the Sky lantern in. Totally recommend and have alreado done so.

Friendly and helpful with my queries. A couple of emails went unanswered, but I was begging a favour for them to rush my order through. They kept me informed. The skylight looks fantastic - exactly what we were after. The builders found it easy to fit.

Great skylight and excellent aftersales.

Good quality roof lantern. Very good communication and delivered on time. Have used Duplus on a number of occasions and can not fault them, would defiantly recommend them.

Ordered a Fixed Flat roof light. Delivered as promised within the lead time quoted. Saturday delivery Quality product, just a shame Duplus don't do an installation service! Let the sunlight shine in

The service was great and for me as someone who has no roofing knowledge they explained what I needed. And once I had made the preach they emailed me all the information I needed to install the product as well as the full invoice. The delivery was when they stated and not too long too wait. The roof lights I purchased look great and were really easy to install.

Generally impressed with Duplus. Very helpful throughout the enquiry. Products exactly as expected and look great on the new conservatory. Only minor gripe would be that the delivery driver turned up at 7.30am, before my builder started work, and wanted to leave the rooflights by the kerbside. Thankfully it was sorted eventually but perhaps an area for improvement in the future

After being recommended by our builder we purchased a lanten roof from Duplus. A very helpful Gavin answered all my questions and the delivery was held until we wanted it. It arrived on the Wirral at 7.30am as advised the previous day by the "delivery driver" who was also very helpful. The roof was fitted in under 1 hour and is a fabulous product, looks superb, we are delighted with Duplus - we're sure that you won't be disappointed!

Very helpful friendly advice. Great value for money and stunning roof lanterns. Would happily recommend.

Good price, excellent quality and fit, exceptional customer service, professional and friendly driver, arrived slightly early and personally phoned to confirm time of delivery. Exceptional e-mail and telephone support. This product is ready assembled, it took four men to Lift it into place and took 20 minutes to fit in.

I purchased a glass lantern window. The price was the best I could find, and the product was delivered with great efficiency and was of the highest quality, in fact much better quality than some more expensive products I have used.

We ordered 2 roof flights from Duplus. They are excellent quality and were delivered on time. The customer service was very professional and efficient throughout.

Excellent service

The advice and help given was excellent. They even kept hold of the roof lantern until we were ready for it to be installed. I would use them again.

Would highly recommend them.

Very happy with the quality of my sky-lights in manufacturing the exact/bespoke sizes with frosted glass and delivery on time. Thank you
