A persistent PPL problem at many Flight Training Organisations is that many people end-up spending a lot more than they were led to believe and not finishing as quickly as they were promised or imagined. The stereotypical excuses/reasons are: they say you need more training, weather repeatedly unsuitable for student pilot, instructor unavailable, aircraft unserviceable or allocated to someone with more clout.The instructor/aircraft availability problem is typical of 'club' and marginal FTO's but can occur at bigger FTO's.
Not up-to-date with current costs but you might now well end up spending £10k or more ! before you get a JAA PPL in the UK. As Tonker suggests, the cheaper and usually much quicker alternative is the (same JAA) PPL in the USA where there are a small number of JAA authorised FTO's which specialise in 3 or 4 week JAA PPL courses. As a student, you ought to have time available for that option.
If you went to Florida, you might get away with under £5k incl. your flight-ask Orlando Flight Training and Ormond Beach Aviation for written quotes.
BTW , advice to get written quotes, on everything applies to anywhere you're considering (even your local 'club'). AVOID ANYWHERE WHICH WILL NOT ANSWER ,OR PUT EVERYTHING, IN WRITING !
Other obvious questions are- does the price quoted include & , if not, how much for:
Landing fees?
Fuel supplements ?
Exam fees ?
Night rating?
Books, headset ?
Another suggestion is get a 'medical' (i.e. don't assume you're fit to fly).
Any FTO including those in the USA will tell you where to go.
