Re-train as a plumber, invest yr cash in the business, build it up, using yr skills in PM etc, and then you'll be able to afford to PPL(H) when you like.
OK, perhaps not entirely serious, but I suspect there's more work for plumbers with a couple of years experience that pilots right now, and expansion of the EU will only bring more people with ex-mil skills that will work for less than a UK guy/guyess, with a UK mortgage.
You've not outlined your other commitments so it's not clear if you are a totally free agent, or just someone totally fed-up, and having sensibly tucked away something to use in phase 2.
