Blue Square Environmental Services provided a first class service. Often called upon at short notice they respond effectively and efficiently in a professional and customer focused ways. Technical knowledge from the office assists the engineers on the ground and helps non-technical clients understand solutions in a clear and straightforward manner. Blue Square Environmental Services is a forward thinking Mechanical & Electrical provider keen to develop with their client base – I would strongly recommend them as either a stand-alone M & E provider or as part of a larger Facilities Management solution.
