Though it was first discussed in the Parliament as early as 1818, a formal policy of metrication only started in 1965. This policy, initiated in response to requests by industry, was voluntary on a sector-by-sector basis, with costs picked up where they fell. In 1969 the Metrication Board was set up to coordinate the programme. Only in 1978, after a carpeting chain store reneged on a voluntary metrication agreement, did the government start issuing orders making metrication mandatory in certain sectors. When the Metrication Board was wound up in 1980, all the economic sectors that fell within its remit apart from road signage and parts of the retail trade sector had been metricated.
