We had external wall insulation installed on our detached bungalow and had an attic insulation upgrade during the summer of 2017. We are very pleased with the results as our house is now much cosier in winter time and holds the heat for much longer after the heating switches off which helps greatly with the fuel costs. The work was efficiently done and cooperation with other workmen was excellent, one even remarked on how helpful Comfort Solutions were in leaving easy access to wiring for outside lights and alarm, etc. All services, TV etc. were left in working order when finished. Even after full payment was made, a workman was sent to make a minor adjustment to downpipes. We have no hesitation in highly recommending Comfort Solutions Retrofit.
