£26k isn't that much, but a few points on the salary:
You'll still be the highest paid turbo prop F/O in the country compared to other companies.
After year 1 your salary will jump at least £3k p/a
You get nice increments per annum there after.
After a few years with the company you'll live comfortably on the salary.
Your real term debt should be manageable compared to other "integrated" courses.
As for Flybe:
You get paid from day one of employment.
You do not pay for your type rating like you would with CTC etc.
You get paid expenses during training.
We still get crew food (some like it, some don't)
You get a company pension
Reasonable time to command if you're willing to move.
Job is almost as secure as it can get.
Good career prospects with lots of jets arriving.
There's loads more to list, but that should keep you going for now
