Do I Need to Declare Cash with My Accounts?

I have a property maintenance business, im currently doing my accounts, some jobs i have been paid cash but i have'nt put this into my bank….. my income and outgoing just break even in my personal bank account (i have no business account at the moment)

so should i declare i have been paid cash on some jobs? I have sent invoices off to certain companies and they paid me cash on some jobs and some cheques, he cheques went into the bank…..

Suggestion:

No one really has to do anything. However, if you want to keep it legal you should declare it.
