We welcome positive feedback from our long list of happy customers who have kindly provided testimony within this web page.

"Good pre-order service, other companies didn't seem to have any customer service. Ecotec brought us a sample so we could see and touch the window before we ordered, which was excellent. Promise date of delivery was met and we were kept informed by Ecotec. Most impressive of all was that when a small scratch was spotted, Ecotec responded immediately. The problem was solved within three days. I can't believe the number of people who have stopped to tell us how good the new windows look!"

Mr & Mrs Webb, Sheffield

"I found working with Ecotec and Rob Speight went well. I was kept well informed throughout the ordering process and everything arrived on time and in good order. I had a couple of issues that I needed help with and Rob was on hand whenever I needed him. The experience of working with Ecotec has been good, in fact spot on."

Mr Jamie Ashton, A Space Architects

"Working with Rob was good, really good; Good communication and awesome quality of product. The delivery arrived when we'd been told it would. The after-sales response has been just a swift and efficient. Excellent service, I would definitely recommend Ecotec and Rationel to anyone"

Mr Graham Clark, Covertek.

"Everything ran as you'd expect, good communications, a couple of meetings to look at the product and the quotations came back very quickly. Once the order was placed, the delivery arrived in the expected lead-time. Ecotec called us to confirm the date and it came. Any queries that I've had since the delivery have been dealt with by both Ecotec and Rationel very promptly. I'd be very happy to use both Ecotec and Rationel again in the future and wouldn't hesitate to recommend them."

Mr Ben Hellawell, Architect, NPS

"Everything was spot on, really good. Ecotec did what I needed them to do quickly and efficiently. Excellent service!"

Mr Matthew Lalley

"Working with Ecotec was very good, I've got nothing but praise. We're not experts and Ecotec guided us along where needed and were happy to speak to our engineer. Even the pricing response was tremendous. This is what won Ecotec the business in the first place. We contacted other suppliers but they took weeks and weeks to get back. Ecotec's response was immediate."
