Around 20 years ago, a close friend got well into his PPL training before parental illness and eventual demise (both) caused him to shelve it.
Forward several years and interest was rekindled.....every lesson had been signed-off by his Blackpool instructor, in his logbook. He completed his training at Barton and the CAA accepted all the logged, signed hours....As far as I can remember his R/T exam was also counted...could be wrong on that, but remember him telling of a crackly headset in a "soundproof" room and having to carry out various R?T procedures/readbacks etc.
AFAIK, that was at Blackpool.
