Accountants Letter Proving Self Employment

Description of support work: I need a letter/certificate on headed paper from a qualified UK based accountant to prove I am self employed. I am a UK citizen and have my UTR number, I am newly registered for self assessment.

Why Do I Need This?
I need to collect commissions on sales from a Spanish company to my UK bank account and to qualify for this I have to provide what they call a "self employed certificate" I have told them that this is not available in the UK, however it seems to be in other EU countries.

Being newly registered with self assessment at the moment all I can provide them with is my UTR number and they would prefer to see something more official looking, they have agreed to accept a certification from a UK accountant that I am self employed until a time I am able to furnish them with my first tax return.

For the record I have been living abroad for many years but am now returning to the UK.

I will provide my UTR and personal details to be included in the document and if required I will print out any information you require from the self assessment website. For quickness I would like the letter to be scanned and sent to me by email if possible.

Thank You.
