Okay Benish, I will reply.
When I did this I paid half up front and went to the USA for the flight instruction, hour building and then Bristol GS course.
So a FAA PPL, (as you only need this) can be done for £3995.00
Plus £800 for extras, just in case and test money.
Hour building 100 hours in a C172 £7570.00
Bristol Ground school course. £2100.00
So total £14465.00
Multiflights course is £33000.00 so half is £16500.00
The above prices are schools I just googled and picked the first one, Bristol GS price is on their website.
Might be worth looking around a bit before you commit to anything
