If your passport is lost or has been stolen, and you need to travel home immediately, you may obtain an Emergency Passport, valid for a one-way trip only, from the nearest British Consulate. To do this you will need to fill in two LS01 - Lost & Stolen passport forms, available from all Consulates, a C1 Passport form, and take with you a Police report (denuncia) and two passport size photographs. If you have any other form of photographic identity, you should also take that. The fee for this service is 57 Euros.

However, it you have the time to wait for an application to be processed, you may apply for a replacement passport from the British Consulate-General in Madrid, in person or by post. You will need to fill in two LS01 Forms, and provide a police report (denuncia), two passport size photographs (one of which must be countersigned by someone of professional standing who has known you for at least two years). The fee for this service is 91 Euros plus 4 Euros for postage and handling, and 59 Euros plus 4 Euros for postage and handling for a child.
