Financial evidence for Ilr application after Gtv

Hi everyone,
I’m preparing my ILR application under the Global Talent route (endorsed funder), after three years on UKRI endorsement where I was endorsed for doing a two years knowledge Transfer Partnership and my expert field is Engineering. I’d really appreciate some guidance on “evidence of previous earnings” and “evidence of earnings in my expert field.”

My situation

I worked:

2 years as a KTP Associate

11 months as an Engineer (Same company from the KTP) Currently 1 month another company, permanent contract as data scientist.

Most of my documents are electronic copies (PDF payslips, letters, etc.)

Evidence of previous earnings I can provide KTP (University employee)

Last 3 months of payslips

Employment letter confirming role and dates

1 Bank statement (can provide more if required)

P60s for the relevant tax years

Note: University can only issue a standard employment letter

1st company (Engineer role)

Last 3 months of payslips Letter from employer on company headed paper confirming:

employment

salary

work in my expert field

Signed by director

1 Bank statement (can add more if required) P60 (if applicable for the tax year worked)

2nd company (current role)

1 payslip
Employment letter confirming I am currently employed and expected to continue

Evidence that earnings were in my expert field

KTP:

Official employment letter (no explicit mention of field)
Additional letter from line manager confirming work in my expert field (not on headed paper)

Note: my Global Talent endorsement was based on this KTP role and the KTO role name is Iot Enginner

1st Company : Letter on headed paper confirming role + salary + expert field (the headed letter is just a normal document with company logo on top but signed by the director)

2nd company : Employment letter confirming role and start date (field not explicitly detailed)

My question

Is this combination of documents sufficient for “evidence of previous earnings”?
