What our customers say About Us

“Had a boiler and underfloor insulation fitted last week, the guys arrived on time and done a great job. I was a bit apprehensive about the insulation as I thought it would leave a mess and disrupt my day but they were professional and tidied up after themselves and even took the rubbish away. Very pleased customer and would 100% recommend.”

“Great Service – I have just had underfloor cladding and a new boiler from Qualis. I can honestly say the service is definitely 5 star. The guys on both days were very helpful, thorough, courteous, and diligent. We are extremely happy with the service we received and would highly recommend… Thank You.”
