Council tax in a student house: all-student vs mixed

The Class N exemption in plain English

Class N of the Council Tax (Exempt Dwellings) Order 1992 exempts a property from council tax if it is occupied solely by full-time students. The exemption is one of the most common and most generous exemptions in the council tax system. It saves a typical student house in a Band D property £2,392 a year at the national average for 2026/27.

The exemption is not automatic. The students have to apply for it through the council, providing evidence in the form of a student certificate from each occupant's university or college. Without the application, the council will issue a normal council tax bill which the tenants will then need to dispute and have refunded. The application is straightforward in most councils, taking 10 to 15 minutes through the online portal.

The full-time student definition

The Class N exemption defines a full-time student as a person enrolled on a course of higher or further education that:

• Lasts at least one academic year
• Requires at least 21 hours of study per week
• Runs for at least 24 weeks of the year

Most undergraduate degrees, full-time postgraduate degrees, full-time professional qualifications, and full-time vocational courses meet the threshold. Part-time courses and intensive short courses do not. Foreign students enrolled in UK universities on full-time courses qualify, including under the Skilled Worker or Student visa routes (the student certificate is the determinative document, not the visa class).

Getting the student certificate

Each university or college issues a free student certificate (sometimes called a council tax exemption certificate) on request. The certificate confirms:

• The student's name and student number
• The course they are enrolled on
• The course start date and expected end date
• The number of study hours per week
• The course duration in weeks per year

The certificate is obtained from the registry, student services, or sometimes the international office (for foreign students). At most universities the certificate can be downloaded directly from the student portal. The certificate is signed (or digitally stamped) by the institution and is accepted by every council in the country as proof of full-time student status.

Applying for the exemption

With certificates from every adult resident, the application is made through the council's online portal. The form requires:

• The property address
• The names of all adult occupants
• The move-in date for each occupant
• A copy of the tenancy agreement
• A copy of the student certificate for each occupant

Once submitted, the council usually processes the application within 2 to 4 weeks. The exemption is then applied retrospectively to the start date, and any council tax already paid is refunded. The council issues a confirmation showing the exemption is in place. The exemption runs for as long as the student status is maintained.

Mixed houses: one non-student tenant

If one adult resident is not a full-time student (for example, a graduate friend who has moved in to take a year off study, or a working tenant in a former all-student house), the Class N exemption no longer applies. The house is no longer exempt because the exemption requires that every adult is a full-time student.

However, the students are still individually disregarded for the purpose of counting adults. The Local Government Finance Act 1992 Schedule 1 disregards each full-time student as if they were not present for council tax counting. So a 4-bedroom house with three students and one non-student is treated as having one adult resident for counting purposes. That one non-student is liable for the full bill but qualifies for the 25 per cent single occupant discount because all the other adults are disregarded.

The bill is therefore 75 per cent of the standard band rate, paid by the non-student. For a Band D property at the national average that is £1,794. The students have no individual liability and pay nothing directly. The students may informally contribute to the household's council tax cost as part of the household budget, but they have no statutory liability.

Houses in multiple occupation with students

A student HMO (a house of 5 or more residents) is subject to the December 2023 amendments to the Council Tax (Liability for Owners) Regulations 1992. The landlord becomes the council tax liable person rather than the tenants. However, if every occupant is a full-time student, the Class N exemption still applies and no council tax is payable.

In a mixed student HMO (some students, some not), the landlord is liable and the bill is the full Band D rate, with no single occupant discount available because the landlord cannot claim it. This is a financially harder position than a smaller student house, where the single occupant discount is available to the non-student tenant. We cover the HMO rules in detail at council tax in a house share (HMO).

Term-time absence and summer vacation

The Class N exemption continues throughout the year, including the summer vacation, as long as the property is the student's main residence and the student remains enrolled on the qualifying course. Students who return home for the summer (so the house is empty for 8 to 10 weeks) still have the exemption in place because the property remains their term-time main residence.

Students transitioning between courses (finishing a course in May and starting a new one in September) have a gap where they are not enrolled. During the gap they are not full-time students for council tax purposes and the exemption may not apply. Most councils take a pragmatic view if the student is transitioning between courses at the same institution, but the position is fact-specific and depends on the university's student certificate.

Year abroad and exchange students

UK students on a year abroad as part of their UK course remain enrolled at the UK university and qualify for the Class N exemption on their UK term-time residence. The student certificate from the home university confirms the enrolment, and the exemption applies even though the student is physically abroad for the year.

Foreign exchange students at UK universities qualify as full-time students if their course meets the 21-hours / 24-weeks threshold. The student certificate from the UK university is the authoritative document. Visa class does not affect the council tax position; both Student visa holders and short-term study visa holders on qualifying courses are full-time students for Class N purposes.
