A really good company to deal with. Very helpful team of people from sales, technical support and delivery. Any time I called, I did not have to wait to speak to the right person and help was immediate. So not only great customer service but also terrific products, well designed and exact fit. Competitively priced.

I was very happy with Bereco’s service levels and the products are excellent, very good quality. I would have no hesitation in recommending them to others.

Simon Hazelton

Beautifully constructed windows which do the job perfectly. Handled Covid disruption effectively. Installation went smoothly. All in all a job very well done. Would recommend without reservation.


Visited the showroom last year and impressed with the finish and quality. Just as delighted with the windows and back door that we ordered. They look fabulous.
