My point was that at the moment you need a CPL to be paid as an instructor. As far as I know there is no date yet for when the new PPL/FI rules will be implemented. I suspect many will wait until the new regs are in place before doing the FI Course, thereby saving several thousand pounds and a lot of time and effort.
The result could be a shortage of new FI's in the short term. I suspect the long term will be just the opposite with too many new PPL/FI's looking for work at their local club rather than relocating to where the jobs are. (A CPL wannabe Airline pilot, hours builder may be more prepared to relocate, particularly if they are looking to build hours ASAP and don't have a Day Job to hold down).
All speculation I know, but, not beyond the relms of possibility I would suggest!
