£8000 cash for a conservatory is not a small business man saving himself the trouble of finding a bank to pay a cheque in, this is someone committing fraud. The victim of this fraud is you and me because it is HMRC who is being defrauded, HMRC who gather in the income to pay for all our public services. I am shocked at the number of people who are the first to moan about 'benefit cheats' and then happily defraud the exchequer themselves by paying huge amounts of cash to tradespeople. I run an honest business with a full audit trail because I am an honest person and because I like to sleep at night. We used to have a neighbour who boasted loudly and publicly about how much cash he ran through his business, how paying taxes and vat was for 'mugs', but also found time to moan about 'immigrants blocking the hospitals and the state of local schools. He just didn't see the connection. Apart from the moral issue, which I obviously feel strongly about, why should you, the customer, take the risk of withdrawing huge amounts of money from your bank? What if it is lost or stolen? The best way to pay is online banking. A tip; for a first payment to a new payee, send £1 first, then once you know it is safely received, send the balance to the account details that you now know is correct.
