Kezza,
I'm sorry to tell you, but a Frozen ATPL, with Perf A and an MCC, isn't going to happen with 25K.
The prices you see quoted are minimums, without test fees, living expenses, licence fees.
Its going to cost at least 40k, and thats without considering loss of earnings.
If ANYONE on pprune has done it for less, I would be amazed.
Be wary of people posting replies to you, who haven't actually gone through the process. I have and it cost me 45k.
Good luck with whatever you decide to do.
