I am seeking advice in respect of Personal Emergency Evacuation Plans. I was specifically looking for information in respect of whether we require a PEEP for every individual or will a comprehensive group evacuation plan suffice

Try http://www.firesafe.org.uk/fire-emergency-evacuation-plan-or-fire-procedure/ for information on fire procedures. As for PEEPs if the emergency evacuation plan, for each person that require one, is identical then you only require one. The main emergency evacuation plan (FEEP) for the remainder of the relevant persons should make reference to the PEEP. It all depends on your fire strategy.
