Beginning on 4 April 1993, in celebration of the programme's 15th anniversary, the first fifteen series of Grange Hill were repeated during Children's BBC's Sunday (and later, Saturday) morning slots on BBC1 and BBC2. The repeats ended with Series 16 in 1999. In the 1990s Grange Hill was repeated in full on digital satellite and cable channel UK Gold, which broadcast the late 1970s and early 80s episodes of the show. In 1998, it reappeared on sister channel UK Gold Classics, which was a digital-only channel showing programmes previously aired on UK Gold, and Grange Hill was part of its schedule. The channel lasted only six months, however, before becoming UK Gold 2 in April 1999. Interest in Grange Hill was renewed in the late 1990s and the series celebrated its 20th anniversary with the introduction of sinister Scottish bully Sean Pearce (Iain Robertson), who carried a knife and slashed the face of a classmate. Cast member Laura Sadler, who was heavily involved in this storyline, died after falling out of a building in June 2003; four years earlier her Grange Hill character Judi Jeffreys had been killed after slipping and falling out of the window of a burning storeroom in the school.
