What Customers Say About KAS Energy
"The KAS representative physically attended to survey the house and old boiler, checking water flow rate etc before leaving a written quote at the end of the visit. This is something I prefer to the other over the phone quotes I had which leave me wondering if additional works might be required for 'unforeseen' circumstances. The quote was very competitive compared to another local company and an online franchise. Kim speedily replied to a lot of my queries and provided other quotes on different boilers without pressuring me to make a speedy decision. This particular project required replacing two Combi boilers in the property and the work was planned to be carried out over two days. In fact the engineer who arrived on time, Alex, was so competent and knowledgeable about the boilers I had chosen that he fitted both boilers on the same day. Attention to safety was a priority and one of the old flues was extended at no extra cost. After commissioning both boilers and final checks on gas pressures etc Alex explained the system and controls to my tenants rather than just handing over instruction manuals, which was much appreciated. The work was carried out to a neat high standard and with due regard to respecting the property. On completion the house was left as clean and tidy as when Alex arrived. Would highly recommend this company."
"Very professional service from KAS. Competent plumber fitted the boiler in a day and explained how to operate in an understandable language. He was very tidy and the price from KAS was very competitive. I would have no reservations about recommending this company."
"Really happy with the service received from KAS Energy, excellent communication and they were able to book me in quickly. Sam replaced my old boiler and was very efficient and professional. I would recommend KAS Energy to anyone and will be using again in the future."
"Sam was very polite and professional. The work was completed and Kimberley kept us up to date with appointment times, availability and documentation. The price was competitive. Overall we're really happy with the work and will be saving their number for the future."
