The choice is your at the end to go learn with them but you have to know that its sometimes hard to find dates that suite your needs for practicals and theres not alot of support from them, the teachers are just people who are retired electricians (The London centre has only 2 electricians!). So dont expects great stuff from them. Although im doing the course with OLCI, Im learning through lots of external sources such as text books off the net due to OLCIs books are full of mistakes and very less explanation. If your a newcomer to the electrical knowledge, I don't recommend this place. When im finished with this place im just going to do the other Inspecting and Testing and 17th Edition with a local college. Hope this make is clear for anyone that interested.
P.S. The advisers on the phone arent assistance for your course needs they are 98% sales team the remaining 2% which are there to help for Q&A are always busy putting you on hold and sometime ask to call back or they say they will call back and you call you back like 2 month later! by then you'll either sort out your problem or finished that practical. Dissapointing stuff. Again i'll state this is the downside of the course.
If anybody asks you didnt hear it from me!
Good Luck.
