ILR Eligibility After Switching from Tier 1 Entrepreneur to Skilled Worker

[nsoddhi]

My husband entered the UK in 28 November 2018 on the Tier 1 (Entrepreneur) route, with a BRP valid until 20 March 2024. He applied for ILR under the Tier 1 Entrepreneur route before expiry, but after an 18-month wait the application was refused this month. He submitted an administrative review within 14 days, so his leave was covered under section 3C. Yesterday, he successfully switched to a Skilled Worker visa.

Can he now apply for ILR under the Skilled Worker route and count the time he previously spent in the UK under Tier 1 Entreprenurer (including the period covered by section 3C while his ILR application was pending and then refused)?

He needs at least one months payslip and corresponding bank statement on his current visa showing his salary.
