Part of: UK Council Tax 2026 — Complete Guide → Council Tax Exemptions 2026
TL;DR: Each Council Tax exemption Class has specific evidence requirements. The billing council cannot grant an exemption on an applicant's word alone - supporting documents are required. Most councils process complete applications within 14-28 working days. Where evidence is delayed, some councils grant a provisional exemption pending receipt of the full documentation. Exemptions can be backdated once evidence confirms the qualifying date.

The General Evidential Principles
Before covering Class-specific evidence, the following principles apply across all exemption applications:
The council bears no obligation to take your word. Council Tax is a statutory liability. Exempting a property from that liability requires the billing council to be satisfied on the legal standard that the statutory conditions are met. The burden of proof rests squarely with the applicant.
Documents must be current and relevant. A care home admission letter from three years ago does not, by itself, prove the person is still in care. The billing council may accept long-standing Class E status on file, but for new applications, recent documentation is expected.
The council can refuse and request additional evidence. A refusal is not final - it is typically a request for more or better evidence. Respond promptly with whatever additional documentation the council requests.
Backdating requires evidence of the qualifying date. If you are applying late and requesting backdating, the evidence must show when the qualifying conditions were first met - for example, when the person was first admitted to care, when probate was granted, or when the student first enrolled.
Class A: Major Repair Works
A property requiring substantial repair works rendering it uninhabitable.
Evidence required:
- Planning permission (if structural works required planning consent)
- Building Regulations approval or initial notice to building control
- Contractor's schedule of works or specification, showing the scope
- Photographic evidence of the uninhabitable condition (typically before works begin) - photographs should show missing or non-functioning kitchen, bathroom, heating, or electrics
- Some councils conduct a physical site inspection as part of the application
The uninhabitable standard typically requires at least three of the four main services (kitchen, bathroom, heating, electrics) to be absent or non-functioning. Cosmetic refurbishment does not qualify.
Class B: Charity-Owned Empty Property
An empty property owned by a registered charity.
Evidence required:
- Charity Commission registration certificate or registered charity number confirming the organisation's charitable status
- Evidence of ownership (Land Registry title or similar)
- Confirmation of current vacancy and when the property became empty
- A brief explanation of the charitable purpose for which the property is held
Class D: Detained Person
A property where the sole resident is in prison, detained under the Mental Health Act, or held under immigration detention.
Evidence required:
- Prison: Letter from HM Prison and Probation Service confirming the prisoner's name, holding establishment, and current detention status
- MHA detention: Letter from the hospital confirming compulsory detention under the Mental Health Act 1983 or 2007, the ward, and that detention is ongoing
- Immigration detention: Home Office letter or Immigration Enforcement documentation confirming detention
All documentation should be on official letterhead and as recent as possible.
Class E: Permanent Care Home or Hospital
A property left empty because the owner has moved permanently into residential care.
Evidence required:
- Care home or hospital admission letter confirming the person's name, the date of admission, the name of the care home or hospital, and that the placement is for ongoing personal care
- GP letter may be requested confirming the permanent nature of the move
- Social services care assessment or placement agreement (if available)
- Confirmation that the property was the person's sole or main residence before admission
The word "permanent" is important. Class E does not apply to respite care, temporary convalescence, or short-term hospital admission.
Class F: Deceased Person's Property
A property left empty following the death of the owner or tenant.
Evidence required:
- Death certificate (initially, to confirm death and notify the billing council)
- Grant of probate or letters of administration (this is what triggers Class F - the exemption runs from the grant date, not the death date)
Timing note: Class F cannot be applied until probate is granted. Notify the council of the death immediately with the death certificate. Follow up with the grant of probate or letters of administration as soon as issued.
Class G: Occupation Prohibited by Law
A property that cannot legally be occupied.
Evidence required:
- A copy of the formal legal prohibition document. This could be:
- Planning enforcement notice
- Closing or demolition order
- Building control condemnation notice
- Court injunction prohibiting occupation
- Other formal legal instrument
The prohibition must be from a competent public authority - a private landlord's instruction to vacate is not sufficient.
Class H: Property Held for Minister of Religion
A property held empty and available for a minister of religion.
Evidence required:
- Declaration from the religious organisation confirming the property is held as a residence to be occupied by a minister
- Deed of trust or property ownership documentation
- Ministerial appointment paperwork confirming the individual's role
Class I/J: Care-Related Vacancies
Class I (owner receiving personal care elsewhere, property empty) and Class J (owner providing personal care elsewhere, property empty).
Evidence required:
- GP letter or care plan confirming the person's care needs and their move to receive care elsewhere (Class I) or a declaration explaining the caring arrangement (Class J)
- Carer's Allowance award letter may support a Class J application
- Evidence that the property is empty and was the applicant's main residence
Class K: Student-Owned Empty Property
A property owned by a full-time student and left empty while they study.
Evidence required:
- CT1 Council Tax Exemption Certificate from the student's educational institution confirming full-time registration
- Evidence of ownership (Land Registry, mortgage statement, or solicitor's completion letter)
Class L: Mortgagee in Possession
A repossessed property held by the mortgage lender.
Evidence required:
- Court possession order granting the lender possession
- Mortgagee in possession letter from the lender or their receivers
- Land Registry entry showing lender's registration as proprietor in possession (if available)
Class N: All Full-Time Students
A property occupied solely by full-time students.
Evidence required:
- CT1 Council Tax Exemption Certificate from each adult resident's educational institution. Each adult must provide their own certificate. The council needs one certificate per adult.
Class S: Under-18 Residents Only
A property where all residents are under 18.
Evidence required:
- Birth certificates of all residents demonstrating they are all under 18
Class U: All Severely Mentally Impaired
A property where all residents are severely mentally impaired.
Evidence required:
- Medical certificate from each resident's GP or specialist confirming that the person has a severe and apparently permanent impairment of intelligence and social functioning
- Qualifying benefit award letter for each resident (Attendance Allowance, PIP daily living, DLA middle/highest care, ESA support component, or Universal Credit LCWRA)
Both elements are required for each resident claiming SMI status.
Frequently Asked Questions
The evidence I need is delayed - can I still apply and get the exemption backdated?
Yes. Apply now with whatever evidence you have and explain in writing that specific documents are pending. Some billing councils grant a provisional exemption pending receipt of the full documentation, particularly for Class F (where probate can take months). All exemptions can be backdated once evidence of the qualifying date is provided.
The council has asked for a site inspection - do I have to allow it?
For Class A applications, a site inspection is sometimes requested. Councils generally have powers to inspect vacant properties where they have reasonable grounds to believe an exemption is being claimed. Cooperating with a reasonable inspection strengthens your application. If you have concerns about the scope or timing, discuss with the revenues team.
My Class E evidence is from 2 years ago - do I need to update it?
For ongoing Class E exemptions, the billing council should have the original admission documentation on file. If the council requests updated confirmation that the person is still in care (typically for annual account reviews), provide a recent letter from the care home. If the person has moved to a different care home, provide the new admission letter.
Can I submit evidence electronically?
Most billing councils accept evidence by email attachment or through their secure online portals. Acceptable formats typically include PDF, JPEG, and PNG. Originals may be requested for inspection in some cases (particularly for probate documents), but most councils accept clear scanned or photographed copies for initial applications.
What if the exemption is refused despite my providing all the evidence?
Request an internal review, providing any additional evidence you believe supports your case. Clearly explain why you believe the statutory criteria are met, with reference to the specific Class in the Council Tax (Exempt Dwellings) Order 1992. If the internal review fails, appeal to the Valuation Tribunal for England (in England), Valuation Tribunal for Wales, or the equivalent Scottish body. Tribunal hearings are free and you do not need legal representation.
