Home / How must changes to the safety certificate be advertised? How must changes to the safety certificate be advertised? The advertising of changes to safety certificates is a legal requirement imposed on local authorities under the provisions of Safety of Sports Grounds Regulations 1987 and the Safety of Places of Sport Regulations 1988. Accordingly, as the law stands, the notice must be published in the local paper to be effective. Local authorities can publish the notice on their website, but it must be in addition to publishing the notice in the local paper rather as an alternative.
