I had a great experience with Hearts Energy. The training was excellent, and Andrew Sibly was a fantastic trainer. He was knowledgeable, patient, and explained everything clearly, making the course easy to understand. The whole team was friendly and professional, and the support throughout was outstanding. I really enjoyed the experience and would highly recommend Hearts Energy and Andrew Sibly to anyone looking for high-quality training and excellent customer service.

Thank you for your positive feedback Sohan. We are pleased you have had an excellent experience with us at Herts Energy for your MLP Gas Course, we wish you luck for your exams and will be here for continued support during the remainder of your course.
Outstanding!
I recently attended Herts Energy for the UK domestic gas course and it was outstanding. The teachers (Spencer and Andy) were so supportive to all students and their classes were excellent. The materials used on the course are excellent. On day 1, all students received their materials and plan for the whole course.
I've attended other trade schools and I know they are not all the same. It's so important for students to do their research ahead of enrolling in courses, because standards vary significantly between providers. Herts Energy is without doubt 'best in class' on the market. Students at Herts Energy have to work hard and focus, but in return, you'll learn so much and leave the school a confident engineer. I would just like to finish by saying thank you to the whole team at Herts Energy for an outstanding experience!

I recently finished the 4-week training at Herts Energy and had a good experience overall. The trainers (Andy) were knowledgeable and clearly knew the subject well, the content was practical and useful. A couple of sessions ran a little quick, but nothing that got in the way of learning. Facilities and organisation were solid throughout. Would recommend to others.
