The windows are very high quality and cost effective.

I selected Lumi for the exposed coastal location of my project. The windows are very high quality and cost effective. Easier to install than UPVC or Aluminium.
My installation company Guy McCullough of Ulverston said they were the easiest windows he had ever installed.
My only criticism of Lumi is one of poor communication during the delivery process, but this is just a hang up of a busy fast growing company.
Any problems are addressed and if you asked me would I use them again it would be a resounding yes.

The windows themselves are in a league of their own. Nothing else like them on the market and they really make the house unique.

We got Lumi windows for our new build house. From the very beginning the service has been excellent from Jamie in sales to Gary and the lads who installed. Exceptional.

We moved in four months ago and the compliments about the house always start with the windows!

As a manufacturer in the construction industry, quality is of upmost importance to us as a business. Building my own home has been both challenging and interesting and the windows and doors were one of the most challenging decisions for us, as aesthetically it could have completely changed the look and feel both the interior and exterior of our home. Not only are Lumi windows unique, chic and very different to anything else we looked at, they are extremely thermally efficient which was very important to us. We moved in four months ago and the compliments about the house always start with the windows! We have been very pleased with the service and quality of the product.

'Our Lumi windows are the key element that truly transformed our house rather than the build being just another extension'

We are extremely pleased with our Lumi windows and slider, and all who see them comment very favourably on them. They have added an extra wow factor to the build that we hadn’t originally anticipated. Our Lumi windows are the key element that truly transformed our house rather than the build being just another extension.
