Had a ventilation system fitted in the loft of a dormer bungalow. I’d already decided what I wanted when I filled in their online form so I wasn’t looking for advice or sales - the guy who called me was very nice and direct, quoted me a flat price and then I got an email with a link to a contract website which gave me all of the information I needed. I accepted the quote and someone called back to book the time which was not a long wait - I think from initial contact to complete it was less than a week. The guy fitting arrived at my house early but because someone was home when I got back 20 mins later he’d already put down the drop cloth, inspected the loft and brought everything needed inside. He was very respectful of my home, kept everything very clean, took his time to make sure everything was done properly. He also thoroughly explained how the system works, which settings to use. I don’t think I’ve got any negatives - communication was quick and clear, the price was what they quoted, the work was clean.

Really pleased with the work carried out to install 2 x extractors and a PIV unit. The work was much more involved than first thought, and the poor guy was working in our loft on the hottest day of the year! But he returned a second day to finish up and the original price was honoured. A pleasure having you in our home and feeling the benefits of the extractors and PIV as soon as they were turned on!

Both the men were very polite and efficient. Even though the weather was absolutely dreadful the man doing the cleaning still got up and cleaned the panels. Would recommend this company.

We brought a house with 12 solar panels just over a month ago. We knew the panels were not serviced or cleaned since installed 10 years ago (2013) We reached out to DES Ltd who completed a full service and cleaning service. Not only was the job done to a high standard but the knowledge shared and showing us how the system worked has be valuable. Highly recommend and thank you. Regards Riad

Fantastic service from Jason and his team. A top class clean for our solar panels (12) and the added benefit of an in depth test report on the entire system. I'd have no hesitation in recommending DES.
