You have variable income hence you fall under catagory B. See the home office example.
The applicant’s partner lives in the UK and is a fashion photographer who does short-term
contract work for several agencies. He has periods without work and the amount he is paid
varies from job to job. Over the last 12 months he has earned a total of £20,000. In the most
recent 6 months his gross earnings are as follows: £3500, £0, £0, £2300, £3400, £500. The
application is made on the basis of meeting the financial requirement under Category B
Under part (1) of Category B, the applicant’s partner’s current annual employment income
= (gross earnings over the last 6 months, divided by 6) multiplied by 12
= ((3500+0+0+2300+3400+500) ÷ 6) x 12
= (9,700 ÷ 6) x 12
Under part (2) of Category B, the applicant’s partner’s actual employment income over last
So both part (1) and part (2) of Category B are met.
