Energize Wales Ltd has been established as a result of the conscious and growing need to reduce our energy consumption both in terms of cost to the consumer and CO2 levels in the atmosphere, which in some part contributes to global warming and its associated effects. The way in which we light, heat and use our buildings all contribute to this. Even small improvements to the energy performance and the way we use our buildings could have a significant effect on our fuel bills and carbon emissions.Energy Performance CertificatesEnergy Performance Certificates (EPC) have been introduced to help improve the energy efficiency of all buildings. If you are buying, selling, leasing or renting a home or commercial property it is now law to have an Energy Performance Certificate.
