In Scotland, all new schools are sprinkler protected, as are new care homes, sheltered housing and high rise flats. In England all high rise buildings over 30 m must have sprinkler protection. In 2011 Wales became the first country in the world to make installation of fire sprinklers in new homes mandatory. The law applies to newly built houses and blocks of flats, as well as care homes and university halls of residence. This law came into force in September 2013.
