How many bank statements when self employed

Hello everyone,
when my application goes in I believe I need to submit my bank statements from the last 6 months correct ?
being self employed I think I will also submit my last two years of accounts, both show I meet the financial level needed so I will show both years,
my accounts end of year was back in April of this year, can anyone seeing this as a problem ?
also do I need to submit any older statements to match up with my accounts seeing they finish before the last six months statements ?
many thanks

@Maharg has just applied today for his second FLR(M) and he is self employed, I'm sure he will enlighten you

@ChoiAndJohn may be able to help you too.

I went back to April 2014, so that one whole financial year was covered.

Also, get an accountant to write a letter stating your earnings, including those since April this year.
