Expert Boiler Installation & Heating Services Across Derbyshire & Nottinghamshire

"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. 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. 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. The work was carried out to a neat high standard. On completion the house was left as clean and tidy as when Alex arrived. Would highly recommend this company."

"YOU WANT A BOILER Fitting KAS are the Number 1. KAS Energy Plumbing and Heating, Alfreton, Derbyshire yesterday installed a new Worcester Bosch wall boiler. They were on time, gave me and my wife full details of what we were looking for and measured up for installation. We were sent a full breakdown of the price and how long it would take. We had got other prices from other companies but they bettered that and gave us an extra 5 years free service cover and an extra 5 years cover on the Worcester Boiler. They turned up on time, carried out all the work leaving no mess. They are fully approved Gas Safe, plumbing and electrical. Brilliant 100%."
