Submitting tax return and accounts

Hi,

I'm putting together my supporting evidence for my partners fiancée visa.

I work full time and meet the required level of income, however I also do a little bit of self employed work on the side.

I will be submitting my tax return for 2013/2014, but do I need to submit a set of accounts as well?

I do it all myself on a spreadsheet (I'm an ex-accountant), and earn a tiny amount (around £100) last year so it's not worth paying to get them done properly. Should I knock together a profit and loss statement and submit it as well?

Cheers,

Scott
