“I have had the pleasure of working with Urmson LLP for that past 17 years carrying out a variety of commissioning projects and plant applications. From air flow balancing on commercial VRV projects to CHW mechanical flow rate testing and commissioning, their engineers integrate as part of our team and as a result it helps our business deliver the high standards our clients expect. Credit to their commissioning engineer, John who is consistently punctual, equipped and able to provide specific SSOW and always demonstrates a clear understanding of the works involved. Thank you.”

“Due to programme constraints, a number of other factors it were always going to be a challenging project, and it’s been a huge achievement to get to where we are at. Kirk and his guys came into a pressurised situation but still managed to put in as much effort as possible and carried out their works to an extremely high standard which was also noticed by the clients’ consultant when the witnessing was carried out without any issues. Arthur McKay & ISG really appreciate the efforts Urmson LLP put in, as it helped push the job across the line”
