Alec came to see us after we were frustrated by our home always being either too hot or too cold so decided to replace our 20 year old boiler. Alec is very knowledgeable about heating systems with modern controls and we knew straight away we would very happy using Alec and his company. The difference post installation is amazing and although I have not received my gas bill I am sure that I will be saving money whilst always being comfortable in our home. Would highly recommend Integrated heating.
