Tier 1 Entreprenur to ILR

(b) taken over or invested in an existing business or businesses and your services or investment have resulted in a net increase in the employment provided by the business or businesses for settled workers by creating the equivalent of at least 2 new full time jobs for settled workers
The jobs must have existed for at least 12 months during your most recent grant of leave or, where that leave was granted less than 12 months ago, for at least the 12 months immediately before the date of your current application.

If you’re on a Tier 1 Entrepreneur visa and your business has been disrupted
You no longer need to employ at least 2 people for 12 consecutive months. The 12 month period you’re required to employ someone for can be made up of multiple jobs across different months.

Time when your employees were furloughed will not count towards the 12 month period.

If you’ve not been able to employ staff for 12 months by the time your visa expires, you’ll be allowed to temporarily extend your stay to give you time to meet the requirement.

These arrangements will continue for applications made after 31 May 2020, where the jobs you’re relying on were disrupted due to coronavirus.
