Do not do any work for a company called nu-tech refrigeration based in Sydney. They do not pay their bills, and make sub-contractors wait for payment. They use subbies as their bank. The owner of this company has been broke before and is looking like doing it again. We have been calling continuously and waiting for over 5 months for works done last year (2011) and still without payment. I am sick to death of sub-contractors always footing the bill for non-paying head contractors. This has to stop. I will be posting this on any available website so that others do not get caught out. this is not an isolated non-payment, i have spoken to many of their sub-contractors and all are overdue for payment.
