Probably worth doing a search on this, Ian - the subject has been done to death over and over again. The 'JAR-compliant licence' is little more than a cheap marketing scam, a licence from any of the 183 ICAO member states is equally 'compliant' and can probably be had far more cheaply than UKFT offer.
As for the 'full JAA PPL', if UKFT are offering this then they are lying to you - the only school on the west coast currently approved to train for a JAA PPL is Anglo-American in San Diego. You have to ask yourself if it's wise to trust an organisation that indulges in such blatantly false advertising.
