"Cannot thank ETA enough, made it so easy and down to earth to learn, also made it enjoyable, cannot thank Scott and Jan enough for all their help when going through course and especially when it came to ACS, made me feel at ease. After helping me get a job, before I had my papers through…..they are always on the end of a phone or WhatsApp if I need any help or info when I started. Always available for any help and always answer or call back asap. As I said. Can’t thank ETA, Scott, Jan, and Tommy and his team enough. Thank you ☺️"

Jan, Scott, Ryan, Gary, Gavin and Mark are absolutely brilliant and always make you feel so welcome. I'm almost finished sitting my gas ACS and wouldn't have got through it without them. The courses offered are all brilliant and are a great starting point if you're like me and decided to change career. Thanks so much for the help and support !"
