The law states that the person needs to require ‘regular’ overnight care. ‘Regular’ has not been defined in terms of a specific amount of care, but it has been said to mean the same as ‘commonly’, ‘habitually’ or ‘customarily’.
The test for whether someone requires ‘regular’ overnight care is if the need for the care arises often and steadily enough to require that a bedroom be kept for this purpose. Therefore, someone who needs overnight care every night all of the time would obviously pass the test, but the law is also clear that the test can be passed in situations where care is only provided on a minority of nights, so long as an extra bedroom is needed for this purpose (for example, this might apply where someone with a health problem only needs care on bad nights).
The law is not clear about whether a ‘non-resident carer’ means a paid care worker or a carer, and therefore it is reasonable to argue that the term should apply to both.
Also, the law does not specify whether it has to be the same carer or carers that provide the care. So, if different members of a family take turns to stay over with an older relative, or if care is sometimes provided by a combination of family, friends or paid care workers, this should not cause a problem.
