The Major Home Builders Group has committed to having only qualified operatives on its sites by December 2010 - through a partnership with ConstructionSkills.
MHBG's 12-strong membership is set to advise its subcontractors that they want all workers to hold CSCS cards by December 2007 and be fully qualified by December 2010.
The partnership between MHBG and ConstructionSkills was set up to tackle skills shortages and training issues in the home building industry.
Redrow group managing director Neil Fitzsimmons said: 'We will expect all persons working on our sites to have a CSCS card or equivalent at the appropriate level, by the end of 2007.'
'This sends a message that the industry wants a qualified workforce recognising that qualified workers get the job done faster, with fewer mistakes and accidents. There are real business benefits to encouraging all workers to become qualified.'
