In order to enter Bulgaria you must hold a valid travel document (eg British passport). For EU citizens, there is no minimum passport validity requirement but you should ensure that your passport is valid
for the duration of your visit.
British citizens, as well as all other EU citizens can enter Bulgaria without a visa and stay for a period up to 3 months. If intending to stay for a longer period than 3 months, EU citizens need to apply for a continuous residence certificate with the Migration Directorate of the Bulgarian Ministry of Interior.
