In a drive to raise standards a new Industry Standards Register is being launched by the Kitchen, Bathroom and Bedroom Industries National Training Group.
Initially for kitchen installers, it will eventually extend across all trades including builders, plumbers and decorators.
In the first three months of this year, Government advice service Consumer Direct received more than 19,000 complaints about builders, plumbers, electricians, decorators and other home improvement traders, estimated at a cost of £80m to homeowners.
Most of the complaints were about shoddy building work, fitted kitchens and central heating installation and servicing.
As part of the agreement with the NAPIT Group, who will run the Register, the new register will provide a dedicated telephone line and email address for enquiries or complaints.
