I think its disgraceful that any school or club cannot find the five minutes it takes to complete the renewal paperwork. I think, if it was the club I used, I would have politely reminded them that if they wanted any more business from me they should find the few minutes needed to keep me current (admittedly the FTO I use is very good at making sure the paperwork gets done in a timely manner).
Furthermore, if the school/club offered to backdate a licence renewal in contravention of clearly defined rules, I’d also think twice about doing any more business with them – if they illegally backdate licence renewals, what else do they backdate (CofAs, insurance, etc???).
