Company Details

Excellent service and excellent products. I ordered 2x 2000mmX1000mm roof lanterns, they arrived sighing 48hours with calls ahead from the delivery company. Well packaged, they are now fitted and look great. Our builder said they are the best he has fitted. Thanks for a great product and service.

Ordered 4x opening rooflights using web form. Delivery dates were not clear and quickly found I needed to speak to sales staff to organise deliveries when the implication was next day from stock. I should have known better but this actually did not hold up. Because of staff absence (at a trade show) there was quite some confusion about electrical installation requirements when I asked for clarification, which was frustrating whilst we were planning for our first fix. When units arrived quality was excellent and we are extremely pleased once installed. There was a mix up with despatch of the switchplates which required some calls and more frustration whilst we had an electrician on site waiting for parts. In the end a few months after install we found that one switch unit was possibly faulty and there was excellent support in terms of replacing this. We are very pleased with the rooflights and they attract many positive comments. Despite of the issues we experienced I do feel Gavin at Duplus was on our side with support, so I would continue to recommend Duplus as a supplier for other projects!

excellent service, quality product, Would definitely use again. 5 stars. Thanks 👍🏻

Excellent Service, informed all the way process. Delivered promptly Product exceeded expectation.

Excellent service from start to finish.

Gavin at Duplus has been exceptional however he has had some difficulties to overcome for us most notably delays in receiving the switches from their suppliers for the motorised roof lights. I would also say that the product is superb (esp as we were adamant on getting a single panel rooflight larger than most others would produce) however as Duplus specialise in commercial projects, organising fitting and how to fascia the upstands is not ideal.

Delivery was fast and easy to organise and when it was delivered the driver was both polite and ready to go the extra yards to ensure the rooflight was placed where it needed to be. The rooflight itself is well made and stylish and I'd have no reservation in recommending the company and product.

Having used Duplus Architectural previously many years ago for a rooflight that is still performing faultlessly. I was very pleased to find that Duplus are still as good a company to deal with as ever; and the two new rooflights ordered were manufactured exactly to my bespoke kerb sizes. They were fitted in minutes also ,with the really easy capping/sealing system now designed. They also allow in so much light...Great.

Excellent customer service and excellent product. Exceeds expectation in all aspects Duplus managed to make a bespoke walk on rooflight to our exact specification. Other companies we tried were unable to cater our request. Thanks to Gavin and the team for all their help.

An excellent roof lantern, well made and dispatched as arranged. Great communication from the sales and technical team.

Very professional from the off. All communication was clear and accurate. The lantern is a lovely item delivered as organised at the prearranged time. My only issue was that the lantern was quite hard to manoeuvre through the front door through the house as rotating it changed the centre of gravity and that meant it was difficult to hold. Easy if held upright. It took 4 people to get it onto the roof. Very straightforward to fit according to our builder. The lantern looks really well and we are delighted with it. Would defo recommend.

Received 2 x new 30 deg roof lanterns they fitted like a glove and great quality thanks to Gavin and his team for providing a great product combined with a good technical support

From order to delivery all questions were answered promptly and fully by a single point of contact - Gavin. The desired delivery date was met. Quality of roof light is great and will order again in the future.

Many thanks to Gavin for his assistance and patience . Our roofers were delayed but Gavin made sure our roof lanterns were kept safe until we needed them. Delivery was exceptional, thank you Simon. Great roof lanterns, glad we shopped around as the lanterns the roofer was going to supply were not as good as Duplus lanterns. Our roofers are impressed and are now going to use Duplus in the future. Jobs a good one! Thank you.

This is the second time I have purchased Duplus Products. The staff are very knowledgeable and helpful. Products are amazing and delivery on . the said day. Overall a pleasure to work with and a great product at the end of it.

Friendly advice,helpful and order arrived on time

We built the upstands to suit your drawings and the rooflights fitted perfectly and look excellent. I would happily recommend these.

Great service from start to finish. The advice given initially was very easy to understand. Delivered on the date quoted at the time of placing order. The delivery driver waited patiently until we checked it.

Recently bought a Roof Lantern from this company. Estimated time of arrival was met, product was stunning. Sales office (Gavin) was always prompt when progressing the delivery and I would recommend the product and company to anyone.
