Thanks so much, Albert! It was a pleasure working with your team!Trustindex verifies that the original source of the review is Google. I recently used Duo Test for PAT testing at my office, and I couldn’t be happier with the service. Booking was quick and easy, and the communication throughout was clear and professional. The engineer arrived on time, was polite and knowledgeable, and worked efficiently without disrupting the team. All appliances were properly tested (not just stickered!), and I received the digital certificate and report the same day—which was a huge help for our compliance records. Their pricing was very reasonable, especially for the level of thoroughness. It’s rare to find companies that are both affordable and reliable—Duo Test absolutely delivered on both fronts. Would highly recommend to any business needing PAT or emergency lighting testing.
