Barrett-Bell Ltd (formerly Advanced Training Solutions) was first established in 2006.
The aim of Barrett-Bell is to provide a reliable and professorial service to help people gain valuable knowledge, skills, experience and qualifications that they may need to start or further their careers within the gas industry. We measure our success on the success of our learners and have a 94% achievement rate. As such ‘word of mouth’ is our main form of advertising. We currently operate and have training centres in Watford and Stevenage.
