“I have had a good working relationship with RJ Urmson Group over the past 7 years whilst working at North Lincolnshire and Goole Hospitals NHS Foundation Trust and Doncaster and Bassetlaw Teaching Hospitals NHS Foundation Trust. They hold maintenance and service contracts for theatre ventilation including verification of ultra clean systems and smoke damper survey and testing. I find them very flexible in their approach, working with agreed times to avoid any disruption to services. Supplying comprehensive reports that are easy to read with detailed feedback on identified issues helps us to target spend on areas before serious problems occur”

“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”
