About Us

Our team of certified building biologists come from diverse backgrounds but share a strong dedication to applying the best practices and safe standards of building biology. Building biology is the art and science of studying building structure, geography, electromagnetic fields, and air and light quality that make up the environment of our home or workplace. Factors in the home environment can affect health and well-being. It is our mission to provide support for creating the best environment for good sleep and healthy living.


In 2015, Building Biology Central Ltd launched its unique home visit services which included EMF and Geopathic Stress assessments and New Home Search. In 2020 we have expanded our team and added new services. For details please click Home Services or Solution Services.
