You're off for PPL. Budget £180 per hour minimum x 45. Then add medical, you'll want class 1 which will be about £700. You'll also need to pay the examiner's fee for the skills test, many many touch and goes; you pay for each one. You'll need equipment too; Use EasyPPL for theory which will be around £130 for all modules. You'll need other various equipment for nav such as ruler, CRP (Get CRP 5 is going ATPL) which is £80ish (don't buy used, fakes are out there, oddly). You'll also want your own headset. Cheap ones are just over £100 new or you can find used David Clarks on ebay. Everyone ends up with Bose A20s or A30s (they are worth it) and that's £1k. Then add on other costs like landing fees when doing land aways, licence application fee to the CAA, SkyDemon subscription, ram mount for your phone. You'll be just over £10k for PPL all in if done in minimum hours at a cheap school.
You won't get hour building in the UK for £10k. You'll be looking at £150 per hour in a C152.
Night rating - expect £1500 at the cheapest.
Consider the possibility of having to pay for a type rating too. Ryanair want 30k Euro.
