TL;DR: Purpose-built student halls of residence are typically exempt from Council Tax under Class M of the Council Tax (Exempt Dwellings) Order 1992 - the "halls of residence" exemption. Students in halls do not pay Council Tax separately. The exemption is held by the operator (university or private provider), not by individual students. Private student houses use Class N instead, which requires all occupants to be full-time students.

The Class M Exemption: What It Is
Class M of the Council Tax (Exempt Dwellings) Order 1992 provides a Council Tax exemption for "a hall of residence provided predominantly for the accommodation of students."
This Class M exemption is fundamentally different from Class N (which applies to student-occupied private properties). The key differences:
| Feature | Class M (Halls) | Class N (Private Houses) |
|---|---|---|
| Who holds the exemption | The operator (university or private provider) | The student occupants |
| Property type | Purpose-built halls of residence | Any residential property |
| Occupancy requirement | Must be predominantly for student accommodation | All adults must be full-time students |
| Scope | Entire building/complex typically | Individual property |
| Administration | Operator manages with billing council | Students apply directly |
Class M applies to the operator - the university, the housing association managing halls, or the private student accommodation company. The operator as a whole is treated as the responsible party for the building, and the exemption covers the entire halls complex.
Individual students in Class M halls do not register for Council Tax, do not receive bills, and do not need to apply for any exemption. Their rent includes or effectively absorbs the result of Class M - they simply do not owe Council Tax.
The Legal Test for Class M
The Council Tax (Exempt Dwellings) Order 1992 requires that the hall is "provided predominantly for the accommodation of students." Courts have interpreted this to mean:
- The primary purpose of the building or complex is student accommodation
- The majority of residents are students
- The building was designed or is managed primarily for student use
The Court of Appeal in Williams v Horsham District Council [2004] EWCA Civ 39 considered the scope of Class M. The judgment confirmed that Class M requires the property to be a "hall of residence" in substance - purpose-built or designated student accommodation operating as a cohesive student living environment. Ad-hoc student accommodation without the institutional character of a hall does not qualify.
This limits Class M to genuine purpose-built halls (whether owned by universities, colleges, or private operators like Unite Students, Vita Student, iQ Student Accommodation) where the "hall of residence" character is clear.
Private Student Accommodation Operators (PBSA): The Class M Question
The growth of Purpose-Built Student Accommodation (PBSA) since the 2000s has created a sector of privately-operated student blocks that are not traditional university halls. Whether these qualify for Class M depends on their structure:
Large institutional PBSA blocks: A 500-bed student block managed by a national operator (Unite, iQ, Vita) designed and operated specifically as student accommodation typically qualifies for Class M. The billing council treats the block as a hall of residence.
Self-contained PBSA studios and flats: Where PBSA is structured as individual self-contained units (each with its own kitchen and bathroom), the Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) may assess each unit as a separate dwelling on the Council Tax list. Class M would then not apply - instead, each individual student occupant is the liable person, and Class N applies if they are a qualifying full-time student.
The distinction matters: Students in Class M buildings pay nothing (Council Tax is handled by the operator). Students in individually-assessed PBSA studios need to apply for Class N exemption themselves.
Class M vs Class N: Key Boundary Cases
Purpose-built halls marketed only to students → Class M: The operator holds the exemption. Students pay no Council Tax.
A private house shared by 4 full-time students → Class N: The student tenants hold the exemption. They apply to the billing council with CT1 certificates.
A PBSA studio with a self-contained unit → possibly Class N: The student is the liable person for their unit. They apply for Class N with their CT1 certificate.
A PBSA block with shared kitchens and bathrooms (cluster flats) → possibly Class M or one dwelling: Depends on the Valuation Office assessment. Some cluster flats are assessed as single dwellings; others as separate units.
A mixed-use building with ground-floor commercial use and upper-floor student accommodation → complex: The Council Tax treatment depends on how each dwelling is assessed and whether the residential part qualifies as a hall of residence.
The Summer Let Problem
Class M requires the halls to be "provided predominantly for the accommodation of students." During summer, when students have left for the long vacation, private PBSA operators sometimes let rooms to non-students (conference guests, tourists, summer workers).
If non-students occupy the halls for an extended period during summer and the "predominantly for students" test is no longer met, Class M may not apply during that period. The operator then becomes liable for Council Tax at the standard empty rate or the rate applicable to the actual non-student occupancy.
Most operators manage their summer lettings carefully to ensure Class M status is preserved year-round, either by limiting non-student lettings or by maintaining sufficient student residency to preserve the "predominantly for students" character.
How Private PBSA Operators Manage Class M
The growth of Purpose-Built Student Accommodation (PBSA) since the 2000s has made the Class M question commercially significant. Large operators (Unite Students, iQ Student Accommodation, Vita Student, Scape) manage their Class M status actively:
Annual registration with the billing council: Many PBSA operators submit annual confirmation to their local billing council that the building continues to be provided predominantly for student accommodation. This formalises the Class M status and ensures the operator's billing account reflects the exemption.
Managing the summer let risk: During the summer vacation, when most students leave, PBSA operators carefully manage how blocks are used. Allowing significant non-student use (conferences, general tourism, short-term lets via platforms) risks disrupting the "predominantly for students" test. Most operators either leave blocks empty during summer (maintaining Class M throughout) or ensure that any non-student summer use is minor relative to the student population during term.
Mixed-use developments: Some PBSA developments include ground-floor commercial units (cafes, shops, laundries). The commercial parts are separately assessed for business rates; the residential student accommodation above retains Class M status. The Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) assesses how to draw the boundary between the commercial and residential parts.
New PBSA developments under construction: A new PBSA block during construction does not yet meet the Class M test (no students are resident). Once the block is first occupied by students and the operator registers with the billing council, Class M applies from the first qualifying occupation. The completion notice issued by the Valuation Office triggers the Council Tax assessment, and the operator immediately applies for Class M.
Parents Paying for Halls: No Council Tax Dimension
A common parental concern: "My daughter is in university halls - do I need to worry about Council Tax?"
No. Class M means the halls are exempt. Your daughter does not owe Council Tax and does not receive a bill. You are paying rent (or accommodation fees) for the halls, which is separate from Council Tax. The rent includes whatever the operator needs to cover their costs, but because of Class M, no Council Tax is passed through.
Frequently Asked Questions
I live in a private student house near campus, not in halls - do the same rules apply?
No. Private student houses use Class N, not Class M. You and your housemates need to apply for Class N exemption yourselves. Each adult resident provides a CT1 certificate from their institution to the billing council. If all adults are full-time students, the property is exempt under Class N.
My halls have some non-student residents (staff accommodation) in the same building - does this end Class M?
Possibly. Class M requires the halls to be provided "predominantly" for students. If a portion of the building accommodates non-students (staff, conference guests), the test is whether the student use still predominates. The operator should be managing this carefully to preserve Class M status. If you are unsure, contact the billing council - but in practice, major PBSA operators manage their Class M status actively.
I'm a postgraduate researcher in university-provided accommodation - does Class M apply?
If you are in purpose-built university halls specifically designed and managed for postgraduate students, Class M typically applies. Your individual student status as an enrolled full-time postgraduate researcher supports the "hall of residence" character of the building. You would not typically receive a Council Tax bill, and should contact your university accommodation office if one arrives.
The PBSA company told me I need to pay Council Tax - is that right?
If your PBSA unit is individually assessed as a separate dwelling (self-contained studio with its own kitchen and bathroom), you may indeed be the liable person for that unit rather than the operator. In that case, apply for Class N exemption using your CT1 exemption certificate from your institution. As a qualifying full-time student, Class N gives 100% exemption and your Council Tax bill is reduced to zero. Contact your institution's registry for the CT1 and submit it to the billing council.
Do halls of residence in Scotland have the same exemption?
Yes. Scottish halls of residence are exempt under the equivalent Scottish legislation, which mirrors the Class M principles. The Council Tax (Exempt Dwellings) (Scotland) provisions operate on the same "provided predominantly for students" test. Scottish students in purpose-built university or PBSA halls do not owe Council Tax. The Scottish Assessors Association confirms this position for Scottish student accommodation.
How we verified this
Class M exemption is from the Council Tax (Exempt Dwellings) Order 1992. The "provided predominantly for students" test was considered in Williams v Horsham District Council [2004] EWCA Civ 39. Class N exemption (for private student properties) is from the same Order. The full-time student definition is from the Council Tax (Discount Disregards) Order 1992. The Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) determines whether PBSA units are separate dwellings. HESA provides context for student accommodation numbers. MHCLG guidance covers Class M administration. The IRRV provides professional guidance to billing councils on student halls exemptions.
