What symbol indicates a product or service has been approved by the British Standards Institution?

The British Standards Institution (BSI) is the national standards body of the United Kingdom. BSI produces technical standards on a wide range of products and services and also supplies certification and standards-related services to businesses.

Within Testing Services, BSI's best known product in the UK is the Kitemark, a registered certification mark first used in 1903. The Kitemark (which is recognized by 82% of UK adults) signifies products or services which have been assessed and tested as meeting the requirements of the related specification or standard within a Kitemark scheme.

The Kitemark is most frequently used to identify products where safety is paramount, such as crash helmets, smoke alarms and flood defences. In recent years the Kitemark has also been applied to a range of services, such as electrical installations; car servicing and accident repair; and window installations.
