With the introduction of quality management systems standards in the 1970s Kitemark schemes were developed in areas such as double glazing and fire safety. As of March 2021, there are more than 450 individual Kitemark schemes covering products as diverse as printed circuit boards and cattle tags, and services as disparate as financial products and flood protection. There are also currently more than 2,500 Kitemark licences, held by, amongst others, Anglian Home Improvements, Chubb Security & Fire Protection, Everest, Hygena, and Tarmac and Valor.
