Limited Company Director misc docs needed or not?

VAT payment proof
Company Incorporation certificate
VAT registration
Company tax return
Current Appointments Report
Quarterly NI bil
HMRC UTR letter
HMRC Corp tax letter
PAYE registration letter
Contract

Are any of the above really needed? I want to show just salary + dividend.

I am about to apply with just -

payslips,
personal and business bank statements,
accountant letter which mentions payments for corp tax, VAT and PAYE tax, invoices, salary and dividends,
dividend vouchers

I am a bit concerned that others seem to be submitting several other docs.

Some help/observation from anyone here who knows for a fact that the docs I don't plan to include are not, infact, very important to include or anything of the sort???

These are only documents requiremed if applicant taking salary and dividend from his own company as director
Working in his/her Own Limited Company Structure
1-Certified Accountant's Income Certificate/letter confirming the exact claiming amount
2-Dividend Certificates
3-Business Bank Statements
4-Personal Bank Statements
5-Company Annual Accounting documents
6-Business Invoices
7-Salary Slips

but it is advisable to submit the following extra documents as well so the case worker has no doubt that applicant earn that income genuinely.

Company Incorporation certificate
Quarterly NI bill
VAT payment proof
VAT registration
HMRC UTR letter only
