Start Your Free Quote →If your boiler is over ten years old, losing pressure, or costing more each year to run, replacement usually works out cheaper than repeated repairs. Older boilers often run at around 60% efficiency. A new condensing boiler runs at a minimum of 90%.
If a repair makes more sense, we will tell you. See our boiler repairs service for diagnostic call-outs.
Most installations are completed in one day. Moving the boiler to a different room, or changing system type, usually takes two.

"KAS Energy recently installed a new combi boiler for me, and I couldn't be happier with the service. From the initial quote through to completion, everything was handled professionally and efficiently. The price quoted was very competitive. A special mention goes to Ross, who carried out the installation. He was friendly, professional, knowledgeable, and took the time to explain everything clearly."

"My old boiler stopped functioning and was leaking horribly over the kitchen. Sam from KAS came to give a quote and explained everything carefully. There was attention to detail when he inspected the radiators in the house and the boiler. After booking the job the follow up conversations with Kim were always immediate and clear and always available. Ross the engineer who came was superb in the way he handled any issue from piping, to drilling and explained everything patiently to me each step of the way. He cleaned up and removed debris like he was never there before. Boiler works great!"
