The British Embassy in Guatemala City has responsibility for political relations and provides consular assistance in El Salvador.

British diplomats meet with representatives from the El Salvador government several times a year to sustain a political dialogue. The British Embassy also invites a cross-section of leading Salvadorans to the Queen's Birthday Party, hosted in alternate years in San Salvador.

The Embassy runs ad-hoc regional projects on climate security and human rights.

The Honorary Consul in El Salvador can provide limited consular assistance to British nationals.
