Our air source heat pump central heating system has now been fully functional for the coldest 3 months of the winter and we’re very pleased with it – the whole fabric of the building is much warmer than with our previous LPG system and everything is perfectly automated, so requiring very little intervention.  All the individuals at Trusted Energy have been a pleasure to work with, and although it took longer than anticipated to complete the installation, the final outcome is excellent. We would certainly recommend the company to anyone contemplating installing such a system.
