This company recently installed oil fired central heating in our seventh century cottage. We cannot recommend them higher! The whole project from the initial survey to completion was carried out to absolute perfection. They gave us a finish date upon starting the job and they kept to it, and also never left until the whole job was finished to our complete satisfaction. This company gave us 100% confidence in what they were doing and it is our pleasure to recommend them to you with every confidence. Well done Havtech, and thank you! We are very much delighted.
