As msp pointed out, by going self-employed you would lose a host of employee's benefits and job security.
The following will clarify your net income:
Employed: Salary £22,000, less personal allowance £6,475, leaves £15,525 taxable, at 20% income tax = £3,105. Net income = £18,895.
Self-employed: Salary £18,000, less personal allowance £6,475, leaves £11,525 taxable, at 20% income tax = £2,305. Net income = £15,695.
Therefore, you would be £3,200 worse off going self-employed.
