If you are budgeting then it may be worth considering the money that you will require to keep yourself employable after completing your training.
I am in training at the moment (ATPL distance learning) but of the feedback I have been getting is that it can take several years to get that first job, all the time bearing the heavy liability of keeping an ME IR current (and more than that, keeping the skills sim-check sharp).
My guiding strategy has been to have an income throughout training and jobseeking. This puts me at a disadvantage compared to the soul who goes straight from and ATPL course into a jet job (i will be close to 30 at qualification), but a whole lot better than those in their early 20s with £80k+ debt and working for £6 per hour.
If you are making financial plans, keep a contingency, work to save money, continue your part time work, but be careful about taking a year out with the career path you have chosen.
