The other thing to bear in mind is that if you cannot afford to train in the UK, can you afford to fly here? The training hours are mearly the first few hours of your flying expenses, admittedly once trained you are (mostly) not paying for an instructors time but the vast bulk of the cost per hour is the cost of the flying and you will want to do that anyway.
The upside is that once trained there are at least various routes to (slightly) reducing the cost of the flying hours (shares, pfa aircraft etc) but the training is only the first bit of a very expensive passion.
Don't let that put you off, just be aware that unless you invest even more in training and get professional qualifications and thus someone else to pay for your hobby, it is the beginning of an ongoing drain on your finances.
WORTH EVERY PENNY IN MY VIEW, just wish I was richer so could do more.
