I used pat testing services from Cad Facilities ltd in March 2011. The company turned up on time which was out of normal working hours which meant they did not disrupt daily operations. The portable appliance testing rate was the cheapest I found and was a bit worried about the quality of the service. However i was pleasantly surprised as they done a quick job and fixed a few items for free, gave us some advice and provided a complete inventory report which was useful. Ray the engineer was polite & courteous and knew his job well.
