The Self-Employment Income Support Scheme is open for applications,

The scheme ensures that the self-employed get the help they need, equivalent to the support offered through the furlough scheme.

The Government will pay self-employed people who have been affected by coronavirus a grant worth 80 per cent of their average monthly profits over the last three years, up to £2,500 a month, for 3 months. The payment will be made in a single installment, up to £7,500, and will be paid 6 working days after the application. 

You can apply using the simple form online at https://www.gov.uk/guidance/claim-a-grant-through-the-self-employment-income-support-scheme.
