We have been working with Watt for several years now and their involvement in our business has grown steadily due to the fact that they consistently continue to provide excellent, cost effective advice and have an ability to articulate complicated aspects of mechanical and electrical design implications to their client in such a way as it is understandable and as such effective decisions can be taken.

They have assisted us with design advice, performance specifications, EPCs and more recently targetting Net Zero Carbon and the evolving green agenda. Most importantly from my perspective, they are a very personable set of people who can integrate well into design teams and deliver first class advice.
