Your search will return information on all existing plaques erected by English Heritage and the three organisations which administered the scheme before it: the (Royal) Society of Arts (1866-1901), the London County Council (1901-65), and the Greater London Council (1965-86).
Many people believe that English Heritage awards blue plaques across England. In fact, the scheme has historically been focused on London only, and this continues to be the case today. However, for a number of years - between 1998 and 2005 - English Heritage trialled a national plaque scheme putting up plaques in certain cities. For information about these English Heritage plaques, erected in Liverpool & Merseyside, Southampton, Birmingham and Portsmouth, download the National Scheme document. Since 2007, English Heritage has concentrated on providing advice and guidance to the many plaque schemes which exist across the country and beyond.
