We design innovative solutions for clients within the commercial, education, healthcare, residential, hospitality and retail industries.
Our heritage
Formed in 1968, Conditioned Environment – a mechanical specialist – fast became a leading supplier of air conditioning services throughout Central and Greater London.
We have since expanded into a multidisciplinary company, specialising in mechanical building services for design and build projects. We provide air conditioning, ventilation, plumbing and heating services for a range of sector clients including commercial, residential, healthcare, retail and education.
We provide complete customer service. Our teams work collaboratively with our clients, both design and build contractors and end-users, providing consistent and reliable support for all systems, from technical design to installation and ongoing preventative maintenance.
Our continued success has led Conditioned Environment to become a trusted advisor for our clients, with many long-standing relationships and an impressive level of repeated business.
In 2020, we’ve focused our development team on helping businesses create safer environments and reducing transmission of the coronavirus. We have focused on the development of the Gateway Personal Protection Tunnel and promoting the benefits of air purification units with UVC-integrated technology, which can effectively deactivate microorganisms.
