Consumers have been told that they can expect registered staff with plumbing course qualifications to abide by professional standards of behaviour.
These remarks were made by Blane Judd, chief executive of the Chartered Institute of Plumbing and Heating Engineering (CIPHE), who was responding to a new HM Revenue and Customs (HMRC) tax campaign targeting plumbers.
Mr Judd explained that there have been suggestions that technicians with plumbing course training may sometimes do cash-in-hand jobs.
But he claimed that registered tradesmen must abide by tax regulations or they will lose this status.
"All professionally qualified plumbing and heating engineers would do their tax affairs as they should do anyway," the CIPHE representative said.
He stressed that the organisation does not involve itself with engineers' individual tax situations, but there is an expectation that they will conduct themselves in the correct manner.
This month, HMRC announced the launch of a campaign offering tradesmen a low penalty rate for disclosing taxable earnings by August 31st 2011.
