TIER1 GENERAL DOCUMENTS SUBCONTRACTOR

[Gyaak]

I'm due to renew my Tier 1 General visa by PEO appointment at Liverpool. I'm currently a self-employed subcontractor, working under a company (agency). For my source of earnings, I have payment summaries from the company, which shows a breakdown of my earnings (gross & tax deducted) for the last 12 months and my bank statement which shows the net payment. Do I need to get the payment summaries stamped by the company? Do I also need an accountant’s letter?
Also I pay my class 2 national insurance by direct debit, which also shows on my bank statement. Am I required to provide any further documents to show that I’m self-employed? (My reasoning is based on this statement from the UKBA website:
If you are submitting self-employed earnings
If you are claiming points for self employed earnings made in the UK, you must provide documents to show that you are registered as self-employed and were registered as self-employed for the period when the money was earned. This is in addition to the documents required to demonstrate earnings.
You must also provide evidence that you were paying Class 2 National Insurance contributions during the period(s) of self-employment.
