From 1 October 2016 the European passport return service is available for EEA, Swiss nationals and their family members to keep their passport while their online application is being processed. You can use this service if you are an EEA or Swiss national and you have applied online for a registration certificate or a document certifying permanent residence.
You must contact a local authority to book an appointment to use this service. You will need to attend an appointment with them within 5 working days of submitting your online application, so you may want to book one before you submit this application. The local authority or premium service centre will tell you the fees you must pay to use this service.
