Your Digital Safety Passport is valid for a maximum period of five years. The expiry date is printed on the card as 'valid until'. Your employer can renew your DSP. There will be no fee to renew a DSP that is about to expire.
If the card is not renewed it will automatically be blocked and can no longer be used. If you want to start using a DSP again after this has happened you will have to apply for a new one.
Simply follow the regular application procedure with the associated production fee.
