There are different schemes, there is a "Furlough" system where those who are not working and are laid off get 80% of their salary paid (up to a max of £2500 monthly), this is intended to save some employers having to release staff, there are also a number of business grants that small and medium sized business can claim, some monthly and some one off interest free loans, not perfect and some get left behind, mainly some self employed who have not been trading for 2 or more years (I think) as there is insufficient income evidence apparently, they would have to claim unemployment benefits which are pretty meagre.
