You mentioned that your partner was laid off from his job after being furloughed... which means you cannot use his pre-furlough salary anyway because he would have to be STILL employed with the same company at the time of applying for FLR(M) in order to be able to use his income to meet the requirements.
Does he have a new job?
If he doesn’t, you are going to have to rely on your self-employment income anyway in order to meet the future income requirement of £18,600 or more per year from 2021 onwards... if you can’t guarantee that you will definitely earn at least £18,600 from your self-employment in the next financial year (2021/22), you will have to use his self-employment income as well.
What are the dates of the financial year you will be using to meet the self-employment requirement, and how much did you earn from self-employment (before tax but after expenses) in that financial year?
If your self-employment earnings were less than £18,600 you can either add any income your partner earned from his job during that financial year, or combine both your self-employment incomes, to make it up to £18,600, but you cannot rely on his pre-furlough income to meet the main income requirement as he is no longer employed by that company.
