RJ Urmson Group have been very accommodating with all of ADT’s requirements and requests. Detailed certification and documentation for works carried out have always been issued promptly. Their engineers have always conducted themselves in a friendly and professional manor and their workmanship is of the highest standard. I would happily recommend RJ Urmson Group to any potential client requiring their services”

“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”
