How long can a British citizen stay out of the UK?

You are allowed to spend time outside of the UK so long as these periods of absence do not exceed 6 months at any one time. It does not matter how much time you spend outside of the UK in total during the required 5-year continuous residence period provided you return each time after a maximum of 6 months.
