You can use savings, but you need A LOT of savings and they must have been in your account in full for at least 6 months.
The first £16,000 of savings cannot be counted and then on top of that, you need 2.5 times the difference between your income and £18,600.
So say you had a total income of £15,000, you would also need in savings:
£16,000 + (2.5 x £3,600) = £25,000
