If I was you I wouldn't even put a single penny into any flight school right now due to the current state of the airline industry (try in 5years). Have you considered joining the RAF? There are many job roles available that are flight related such as pilot, flight operater, air controller and more. This will be good on your CV when applying for a pilot role plus you could save up for your flight training. In the meantime just wait and find some valuable work experience.
Do not I repeat DO NOT be misled by the big flight schools into spending £100k. Don't be a fool
