Part of: UK Council Tax 2026 — Complete Guide → Council Tax Exemptions 2026 — All 12 Exempt Classes Explained
TL;DR: Class K Council Tax exemption applies to properties owned by a full-time student that are left empty - typically when a student inherits or owns a property but lives elsewhere at university or in student accommodation. The property must be empty and owned by the qualifying student. It differs from Class N (where students occupy a property): Class K covers student-owned empty properties; Class N covers student-occupied properties.

The Legal Basis for Class K
Class K of the Council Tax (Exempt Dwellings) Order 1992 provides a Council Tax exemption for properties that are:
1. Owned by a person who is a full-time student
2. Currently empty (unoccupied)
Class K addresses a specific scenario: a student who owns a residential property but who is living elsewhere (at university, in student halls, or in student rental accommodation) while studying. The property they own stands empty during their student years.
The Council Tax (Discount Disregards) Order 1992 provides the definition of "full-time student" that Class K relies on.
The Local Government Finance Act 1992 provides the enabling power.
Class K vs Class N: The Critical Distinction
Students and billing councils sometimes confuse Class K and Class N. The distinction is fundamental:
Class N (Occupied student household): Every adult resident of the property is a full-time student and they are living in the property. The property is occupied. Class N gives 100% exemption to the occupied property.
Class K (Empty student-owned property): A full-time student owns a property but does not live in it - it is empty. The student lives elsewhere (typically in their university town). Class K gives 100% exemption to the empty property they own.
These are completely different scenarios:
- Class N: student house share in a university city (occupied, exempt).
- Class K: student who owns their own home but has left it empty while at university (empty, exempt under Class K).
When Does Class K Arise in Practice?
Class K is less commonly applied than Class N because it requires the student to own a property. The typical scenarios are:
Student who inherits a property: A student whose parent or other relative dies and leaves them a property in their will. The student is living in student accommodation near their university; the inherited property stands empty. Class K applies to the empty inherited property during the student years.
Student who owned a property before starting university: A mature student who bought a flat or house before returning to full-time education. They leave their property empty while studying (perhaps because letting it out would be impractical or they intend to return). Class K applies.
Student who receives a property as a gift: Similar to inheritance - if a property is given to the student by a relative and the student does not live there, Class K may apply.
The "Last Occupied as Main Residence" Requirement
For Class K to apply, the empty property must have been previously occupied by the student as their main residence, or be a property they own but have never occupied (for example, an inherited property they have never lived in). The Council Tax (Exempt Dwellings) Order 1992 requires that the student last occupied the property as their main residence before the period of vacating.
In the inheritance scenario: the student never lived in the inherited property (it was the deceased's home). Can Class K still apply? In practice, most billing councils apply Class K where the student owns the property and it is empty during their studies, even if the student's main residence before university was somewhere else (a parental home, for example).
The Full-Time Student Definition
The definition of "full-time student" for Class K is the same as for Class N and the student disregard:
- Course lasting at least one academic or calendar year
- Requiring at least 24 weeks of study per year
- Involving at least 21 hours per week of study, tuition, or supervised work during term time
The HESA (Higher Education Statistics Agency) data confirms that typical full-time undergraduate and postgraduate taught courses at UK universities meet this definition.
Evidence Councils Typically Request
Council Tax Exemption Certificate: Issued by the student's educational institution, confirming they are a full-time student on a qualifying course. This is the primary student status evidence.
Ownership documentation: Land Registry title document or solicitor's letter confirming the student owns the property.
Confirmation of vacancy: Statement that the property is empty and not let to tenants.
Evidence of student's current residence: Confirmation of where the student is living during their studies (their university accommodation, student rental address, etc.).
What Disqualifies Class K
Property let to tenants: If the student has let the property to tenants (even other students), Class K does not apply. Class K requires the property to be empty. The tenants would be the liable persons during the tenancy, and Class N might apply if all the tenants are full-time students.
Student occupies the property themselves: If the student lives in the property they own while at university (perhaps they are studying locally and commute), it is not empty. Class N might apply if they share with other students and all are full-time students.
Parent owns the property, student child lives elsewhere: Class K is for properties owned by the student. If a parent owns a property in the university town and the student child lives there, the parent is the owner. Class K does not apply to the parent's property. The student's exemption situation depends on the occupancy and whether other arrangements (Class N if all occupants are students) apply.
Class K in the Context of Student Property Ownership
Student property ownership is more common than is sometimes assumed. Several routes lead to students owning property:
Student who purchased before returning to study: A person in their 30s or 40s who owns a flat or house and returns to full-time study (perhaps for a career change or professional qualification). They may leave their property empty while studying, particularly if their university is far from their home address.
Student who inherits mid-course: A student whose relative dies during their studies may inherit a property. The administration of the estate and transfer of the property may take months; the student continues studying while the property stands empty.
Young student investor: Less commonly, a younger student may have received a property as a gift from parents as a tax planning measure or family arrangement. The student owns the property but lives in student accommodation.
Student who bought under a shared ownership or assisted purchase scheme: Some universities operate shared ownership or staff-and-student housing schemes. A student who has purchased a share in such a property and is not occupying it may qualify for Class K on their share.
In all these scenarios, Class K provides the same protection: the student-owned, empty property is exempt from Council Tax during the period of full-time study.
Practical Steps for Claiming Class K
Step 1: Obtain a Council Tax Exemption Certificate from your educational institution confirming you are a qualifying full-time student.
Step 2: Confirm your ownership of the property (Land Registry title document or solicitor's confirmation).
Step 3: Contact the billing council for the area where the property is located (not where you are studying). Most council Tax teams are unfamiliar with Class K compared with Class N - you may need to explain the exemption clearly.
Step 4: Provide: the exemption certificate, ownership evidence, and confirmation that the property is empty and not let to tenants.
Step 5: Request backdating to the date your full-time student status began (or the date the property became empty, if later).
Comparing Class K to Other Student Tax Provisions
| Provision | Who | Property Status | Effect |
|---|---|---|---|
| Student Disregard | Full-time student residents | Occupied | Student not counted in adult tally |
| Class N | All adult residents full-time students | Occupied | 100% exemption |
| Class K | Full-time student owner | Empty | 100% exemption |
Class K is the only provision that specifically addresses student-owned empty properties rather than student-occupied properties. Its under-use reflects the relative rarity of student property ownership and the fact that billing councils less frequently encounter Class K applications compared with Class N. Where a student does own an empty property, Class K is often overlooked - the billing council may continue charging empty property Council Tax rather than applying the exemption automatically. Students who own a property and their families should be aware of Class K and proactively apply to the relevant billing council rather than assuming the council will independently identify the exemption entitlement.
Duration and Ending
Class K lasts as long as:
- The student remains a full-time student on a qualifying course
- The property remains empty
- The student continues to own the property
Class K ends when:
- The student's course ends (graduation or withdrawal)
- The student lets the property to tenants
- The student moves back into the property
- The student sells the property
After Class K ends and if the property remains empty, standard empty property rules apply.
Frequently Asked Questions
I'm a student and my grandmother left me her house - does Class K apply?
Yes, provided the inherited house is empty and you own it. Apply to the billing council for the inherited house's area with your Council Tax Exemption Certificate from your institution and evidence of your ownership of the house.
Can I still qualify for Class K if I go back to my property during holidays?
Class K requires the property to be "empty." If you return to the property for holiday periods, it is technically occupied during those times. However, brief visits to check on the property or short stays do not necessarily disqualify Class K if the property is treated as empty (not your main residence) throughout your studies. Discuss with the billing council - in practice, many councils take a pragmatic approach to student-owned properties where the student uses them only intermittently.
I bought a flat before I started university but I'm now living in student halls - does Class K apply to my flat?
Yes. You own the flat and it is now empty because you are living in student halls during term time. Apply for Class K with your exemption certificate and evidence that the flat is empty.
What happens to Class K in the summer when I'm not at university?
Class K continues through vacations as long as you remain enrolled as a full-time student and the property remains empty. The student status persists through the summer if you are enrolled on a course that continues in the next academic year.
My property is listed with an estate agent for sale - does Class K still apply?
Class K requires the property to be empty and owned by the student. If the property is listed for sale but not yet sold or exchanged, Class K can still apply - the student still owns it and it is still empty (assuming no one has moved in as part of the sale process). Class K ends when the sale formally completes and the student ceases to be the registered owner. Inform the billing council of the sale completion when it occurs.
How we verified this
Class K eligibility is from the Council Tax (Exempt Dwellings) Order 1992. The full-time student definition is from the Council Tax (Discount Disregards) Order 1992. HESA publishes student course data that confirms typical courses meet the full-time student threshold. MHCLG guidance covers Class K administration. The IRRV provides professional guidance on the distinction between Class K (student-owned empty property) and Class N (student-occupied property).
