As specialists in the Heating, Ventilating and Air Conditioning industry, Diffusion strives to offer added value to our customers. 

Utilising the expertise of our in-house Product Development and Technical team we can test your chosen Diffusion product at our UK HQ in West Molesey, Surrey.  Here we can simulate how it will perform under precise, often complex project-specific parameters.  

Diffusion’s facilities provide the opportunity for the client to observe the product during testing. These tests are conducted in accordance with a detailed method statement explaining each stage of the performance testing process therefore, the client can feel assured that the product will meet and often exceed their precise project needs and be Certified in their presence.

Being able to invite customers to witness the product performance prior to taking delivery of the product helps to develop relationships, trust and enhances the overall experience, providing confidence, and delivering peace of mind. Below are the three key tests we offer. Simply email our team for assistance diffusion@diffusion-group.com
