Pre-settled status is granted for a limited period of time which allows the holder to reach 5 years in the UK and then to apply to convert this into settled status. If the individual is unable to convert their pre-settled status into settled status, for example because they have spent more than 6 months in any 12 month period outside the UK (see below) they cannot renew their pre-settled status and so it will lapse on the expiry date.
In addition, pre-settled status is lost if you spend more than 2 consecutive years outside of the UK and settled status is lost by spending 5 consecutive years outside of the UK.
It can also be lost if you no longer meet the eligibility criteria, for example in relation to criminal offences.
