Are you really sure you want a "fast" PPL? The problem with getting a "quickie" is that you will be crap! You will have very limited exposure to weather, airfields and the environment you will be soon be operating in. Get it wrong, which will be simple, and you'll be featuring in a two inch narrow column on page 17 of a local rag. You won't make it into "Rumours and News" unless you do something spectacular. Do yourself a favour and take your time to allow some of the knowledge you will need to soak in.
For what it's worth, the flight school you have seen sound a reasonable bunch if they said 10-14 months.
