Proof of source of funds – bank statement and sponsor visa

I submitted my papers to the British Embassy and everything went great. After a day or two, I had to withdraw some money (not from my regular source of income) to lend to someone. I pay it into my bank account or not, knowing that I'm going to the UK for business reasons. The company I work for is my sponsor and they have provided me with all the necessary documentation.

Thank you for your help.
