grass strip basher is quite reasonable.
At your age, if you want to fly fixed wing, you better get involved. At your age, you can get lots of heavily discounted and FREEE flying and I don't mean only cheapo or free gliding (improves your stick skills etc).
Though I can feel for your brother. He won't get as easy way into job with helicopters. But hey ho, rack up a debt and daddy will cough up, if secured on your/his house, isn't it so?
You can do your training fairly cheaply. You can do your CPL and SE IR, thus saving on renewals when there would be no good hiring market later on, the SE IR keeping the ATPL theory credits and then when time right, do your ME IR.
Actually, NO. Just do the CPL/MEIR modules once the job market is good. Beforehand get other requirements out of way. BTW, you can use some gliding PIC towards the CPL issue 200hrs, but it's not worth the aerotow only training in terms of hours/expense. If you like flying, gliding is great fun and winch launch training is cheap for youngsters with almost nil membership and reduced flying.
If you're involved in gliding, get your RAF/air league scholarship for PPL(A). Get some towing in over the summer - PIC time for you. Do whatever extra XC time before or after.
There are many ways to save cash while building skills, airmanship, knowledge. Oh, and btw, doing Uni that can get you reasonably paid job, is important, too. There are people against it, but trust me, it's easier to study when you're young and staying at home with parents. Also saves money for living cost.
I spent best part of my 20's working on my rotary (and fixed wing alongside, partially) training/career and I know value of money. When at your age, I couldn't even dare to hope for aviation career due to my background and life. So yeah, count yourself lucky to be in well-off family, in the UK, at that age.
EDIT: Just my personal opinion, but, why don't you quit that ridiculous motto/location in your profile,
FDP? For someone in your circumstances, it makes more fun of you than some benefit and I doubt it'd impress chicks this way on this 'aviation anoraks' forum anyway..
