Part of: UK Council Tax 2026 — Complete Guide → Council Tax Exemptions 2026
TL;DR: Some Council Tax exemption Classes are time-limited (Class A: typically 6-12 months; Class B: 6 months; Class F: 6 months from grant of probate). Others are unlimited for as long as the qualifying condition persists (Class D, E, G, L, N, U, and others). When a time-limited exemption ends, full Council Tax resumes. Notify the billing council within 21 days of any change in circumstances.

Time-Limited Exemptions
The following exemption Classes have defined or typical time limits:
Class A - Major Renovation: A property requiring substantial repair works to make it habitable. The exemption is discretionary - billing councils can apply it for up to 12 months (some councils have reduced this to 6 months or eliminated it entirely following changes introduced under the Levelling-up and Regeneration Act 2023). Check your specific council's current policy.
Class B - Charity-Owned Empty: A property owned by a registered charity and kept empty between charitable uses. The exemption lasts 6 months from when the property became vacant. After 6 months, full Council Tax at the empty rate applies.
Class F - Deceased Person's Property: The property of a deceased person who was the sole owner or tenant, administered through their estate. Class F runs for 6 months from the date the grant of probate or letters of administration is issued - NOT from the date of death. After 6 months, full Council Tax resumes.
Unlimited Exemptions (While Conditions Persist)
The following Classes continue indefinitely for as long as the qualifying circumstances apply:
Class D - Detained Person: A property whose sole liable resident is detained in prison, under the Mental Health Act, or under immigration detention. Unlimited while detention continues.
Class E - In Care Home or Hospital: A property whose sole resident has moved permanently into a care home, hospital, or similar institution. Unlimited while the former resident remains in care.
Class G - Occupation Prohibited by Law: A property that cannot legally be occupied (planning enforcement notice, closing order, formal condemnation). Unlimited while the prohibition remains in force.
Class H - Held for Minister of Religion: A property held by a minister of religion and kept unoccupied pending occupancy. Unlimited while the qualifying purpose applies.
Class I - Receiving Care Elsewhere: A property left empty because the owner has moved away to receive personal care elsewhere (but not in an institutional setting). Unlimited while the care arrangement continues.
Class J - Providing Care Elsewhere: A property left empty because the owner has moved elsewhere to provide personal care to another person. Unlimited while the care arrangement continues.
Class K - Student-Owned Empty: A property owned by a full-time student and left empty while they study. While student status persists.
Class L - Mortgagee in Possession: A property repossessed by the mortgage lender. Unlimited while the lender holds possession.
Class N - All Full-Time Students: A property occupied solely by full-time students. Unlimited for as long as all adult residents are qualifying full-time students.
Class S - Under-18 Residents Only: A property occupied solely by people under 18. Until any resident reaches 18.
Class U - All Severely Mentally Impaired: A property occupied solely by persons who are severely mentally impaired. Unlimited while SMI status of all residents persists.
What Happens When a Time-Limited Exemption Ends
When Class A, Class B, or Class F reaches its time limit:
Full Council Tax resumes from the day after the exemption ends. The billing council issues a new demand for the resumed liability.
The long-term empty premium clock may restart or continue. Under the Levelling-up and Regeneration Act 2023, billing councils in England can charge premiums for long-term empty properties (typically 100% premium after 1 year empty, 200% after 5 years, 300% after 10 years). The exemption period may or may not count toward the vacancy period depending on the council's specific policy and the Class involved.
For Class F specifically: The 6-month Class F period typically runs from grant of probate. The total vacancy may have already been considerable (e.g., 2 months pre-grant + 6 months Class F = 8 months empty before full CT resumes). The long-term empty premium clock starts at the billing council's empty property policy threshold after Class F ends.
The Long-Term Empty Premium Interaction
When a time-limited exemption (particularly Class A or Class F) ends, the property's total vacancy period may have already reached or be approaching the threshold for the long-term empty premium:
Under the Levelling-up and Regeneration Act 2023, English billing councils can charge:
- 100% premium after 1 year empty
- 200% premium after 5 years empty
- 300% premium after 10 years empty
Class F scenario: The property was empty from the date of death. It takes 2 months to obtain probate. Class F then runs for 6 months. At the end of Class F, the property has been empty for 8 months. The billing council begins the empty property charge at the standard rate. If the property remains empty for a further 4 months (total 12 months), the 100% premium begins.
Class A scenario: A property undergoing renovation may have been empty for months before the Class A application was made. If the Class A exemption runs for 6-12 months and the renovation extends beyond that, total vacancy quickly reaches the 1-year premium threshold.
Executors and property owners with time-limited exemptions should plan proactively for what happens after the exemption ends.
Annual Reviews and Ongoing Eligibility
For unlimited exemptions, billing councils typically conduct periodic reviews to confirm ongoing eligibility:
- Class E (care home): councils may request annual confirmation that the person remains in care
- Class N (all students): councils may request updated CT1 certificates each academic year
- Class U (SMI): councils may request annual confirmation of qualifying benefit and medical status
You must notify the billing council within 21 days of any change in circumstances that would end the exemption - for example, if a student leaves their course, if a detained person is released, or if a care home resident returns home.
The Appeal Route
If the billing council refuses to grant or extend an exemption, or terminates one prematurely:
1. Request an internal review by a senior revenues officer who was not involved in the original decision. Provide any additional evidence that supports your case.
2. If the internal review fails or is not completed within a reasonable time (typically 4-8 weeks), appeal to the Valuation Tribunal for England (in England), the Valuation Tribunal for Wales (in Wales), or the equivalent Scottish body.
3. The tribunal considers whether the statutory criteria for the claimed Class are met on the evidence. Tribunal hearings are free of charge. Many cases are resolved at the internal review stage.
Frequently Asked Questions
My Class A renovation exemption ran out 2 months ago - can I apply for an extension?
Some billing councils have discretion to extend Class A beyond the standard period where renovation is genuinely ongoing and evidence supports it. Contact the revenues team with updated contractor progress documentation. However, many councils have reduced or removed Class A following the Levelling-up and Regeneration Act 2023, so extension is not guaranteed.
Class F expires next month and the estate still hasn't sold the property - what do I do?
Full Council Tax resumes after Class F expires. Contact the billing council before expiry to understand the rate that will apply and the empty property premium timeline. Consider whether a beneficiary could move in (ending Class F early but shifting liability), whether the property can be let (tenant becomes liable), or whether you must accept the resumed Council Tax as an estate cost.
My mother is in a care home - does her Class E exemption last forever?
Class E continues indefinitely while she remains in care and the property is empty. It ends if she returns home, if the property is let or sold, or if a beneficiary moves in. On her death, Class E ends and Class F may begin (if probate is needed and the estate retains the property).
I have Class N exemption for my student household - does the exemption run out at the end of term?
Class N continues for as long as all adult residents are full-time students registered on their qualifying courses. During the summer vacation, students typically remain registered as full-time students (they have not completed or formally left their courses), so Class N continues through the summer period without interruption. The exemption ends if a non-student moves in, if any student completes or withdraws from their course, or when the property is vacated between tenancies.
What happens to Class L when the repossessed property is eventually sold?
Class L ends on the completion date of the sale. The buyer becomes the liable person from the completion date. Notify the billing council of the sale completion date. The lender (as mortgagee in possession) is no longer liable from the completion date, and any liability for periods after completion falls to the buyer.
