Continuity of residence should be considered to have been broken if the applicant has
spent a total of more than 18 months absent from the United Kingdom during the
period in question.
Subject to that, continuity shall not be considered to have been broken where an
applicant is absent from the United Kingdom for a period of 6 months or less at any
one time, provided that the applicant has existing limited leave to enter or remain
upon his departure and return.

To benefit from this, an applicant must have current leave covering the whole of the
period spent out of the country and will have been readmitted, on return from his
absence, to continue that period of existing leave. A person who leaves the UK when
one period of leave expires, and comes back with a fresh grant of leave, will not be
resuming his continuous residence, but will instead be starting a new period of
residence in the UK.
