Guidance on ILR Requirement - 180 Days Absence

Dear experts,

I am due to apply my ILR through the 5 year Skilled Worker/Tier 2 General route in Oct 2021.

Long story short, my previous employer, with whom I was employed from Sep-16 to Apr-21 is refusing to provide me absence details. They are only willing to provide a standard reference letter. My absences throughout the years are more than 30 days due to extensive business trips but is within the 180 threshold.


Will the following document be sufficient in-lieu where by absence is more than 30 days per year?

1. Employment letter from previous employer stating my start and end dates
2. Email correspondence where previous employer said that the details of absence cannot be provided
3. A cover letter to home office stating my previous employer cannot provide me an absence letter
4. An Excel sheet made by me capturing the duration I am out from UK to show the total count per year is not 5. Home Office SAR results showing dates of all travel.

Please help! Thank you in advance.
