You must have been physically present in the UK exactly 5 years before the Home Office receives your application. Your application may be rejected if you were not. The Home Office will consider if there are special circumstances, for example: you were not able to live in the UK at the start of the 5 year period because of health reasons or travel restrictions you were told to leave the UK during the 5 years but this decision was later overturned
