The CHEESE Project (Cold Homes Energy Efficiency Survey Experts) is an award-winning not-for profit service unique in the UK. We specialise in low-cost Thermal Imaging surveys carried out by our Energy Tracers as an integral part of any retrofit or energy efficiency DIY project. Our process empowers and motivates householders to take informed action using the powerful visual data we provide. Our protocol, kit and software has been developed in-house and is designed to keep costs low and image quality high. TI is the natural front-end of retrofitting as the 'ground-truth' data ensures no time or money is wasted during the subsequent retrofit. We run Energy Tracer training courses.
