We have used Dolphin to do our PAT testing since 2011. They test all of our office electricals, as well as the many vacuums that we have spread across the city of Brighton and Hove. It’s logistically a complex task that Dolphin undertake each year, having to go to multiple sites in order to ensure our electrical equipment is safe and compliant. The communication of faults found is excellent which is essential for the safety of our cleaning teams. The PAT testing is thorough and professional with a certificate of compliance issued when testing is complete. I would highly recommend them for PAT testing needs of all businesses.
