At the beginning of 2015 the Construction Leadership Council (CLC) announced via the Industrial Strategy: Construction 2025, that industry, including trade associations, contractors, clients and government, should specify and promote card schemes displaying the CSCS logo with no equivalents accepted.
This is known as the One Industry Logo action. Among the requirements set out by the CLC is that all construction industry card schemes must operate with nationally recognised qualifications (usually NVQ/SVQs) in place for all occupations.
