Always verify from the local authority of your area what benefits and discounts are available for student. Local authorities control council tax support. Each one decides what help to offer its residents.
General Tips to all students
Stay with other students; full-time student living alone or with other students you don’t need to pay council tax, it doesn’t matter how how are staying together.
Living with non-students; Council tax cost is based on two or more adults living together. Some people – like students, people on apprentice schemes and carers (see Gov.uk for a full list) people under this group are known as ‘disregarded people’, which means they’re entitled to a council tax discount, they are not considered as adults
More so, if a student lives with a non-student, the student is disregarded. It shall be considered as one adult, the council task will be reduced by 25%.
Live with more than one non-student? Here, while the student again is exempt, because there are two non-students the house has to pay the full 100% charge.
