Depends on the quality of the training. With CPL/IR saving few pounds an hour might cost you more in the end.
There are many circumstances to consider. One thing you want to make sure of is that the basics and standard of quality will help you when you go on to your commercial training.
Maybe your current school is excellent, maybe they are not, time will only tell. Saving few hundred pounds now, might cost you more in training later, maybe not. Impossible for me to judge how good your current school is. However for me Stapelford have delivered all with reasonable price, as expected!
That is for me quality, not how the food is or the reception ladies are, by the way they have been excellent with me, always!
