of structures were severely damaged, and numerous cattle were killed, prompting emergency aid provided by the British government. In 2005, the islands were given a United Kingdom post code (TDCU 1ZZ), to make it easier for the residents to order goods online. On 13 February 2008, a fire destroyed the island's four power generators and fish canning factory, severely disrupting the economy. On 14 March 2008, new generators were installed and power restored, and a new factory opened in July 2009. While the replacement factory was built, M/V Kelso came to the island as a factory ship.

Nightingale Island has no fresh water, so the penguins were transported to Tristan da Cunha for cleaning. On 13 November 2020 it was announced that the of the waters surrounding the islands will become a Marine Protection Zone. The move will make the zone the largest no-take zone in the Atlantic and the fourth largest on the planet. The move follows 20 years of conservation work by the RSPB and the island government and five years of the UK government's Blue Belt program support. A total solar eclipse will pass over the island on 5 December 2048. The island is calculated to be on the centre line of the umbra's path for nearly three and a half minutes of totality.
