Perhaps considering joining the Services and serving your country for a few years to repay learning to fly?
That approach will go down like a lead balloon at the Armed Forces Careers Office (AFCO). It will save you the effort of having to pass Officer and Aircrew Selection Centre (OASC) because you will not get that far. You need to demonstrate that you want to be a military pilot, not just someone seeking an alternative route into civil aviation.
