TL;DR: Class B Council Tax exemption applies to properties owned by a registered charity that are empty and whose last use was in pursuit of the charity's charitable objects. The exemption lasts up to 6 months from when the property became empty. After 6 months, full Council Tax resumes. The charity must be registered with the Charity Commission for England and Wales, OSCR in Scotland, or an equivalent regulator.

The Legal Basis for Class B
Class B of the Council Tax (Exempt Dwellings) Order 1992 provides a Council Tax exemption for properties that satisfy three conditions simultaneously:
1. The property is owned by a registered charity (or a body or institution established by Royal Charter for charitable purposes)
2. The property is currently unoccupied
3. The property was last used in pursuance of the charity's charitable objects
The enabling power is section 4 of the Local Government Finance Act 1992. The Charities Act 2011 provides the framework for what constitutes a registered charity in England and Wales.
The exemption recognises that registered charities may temporarily hold residential property in pursuit of their charitable work - providing accommodation between beneficiaries, holding inherited bequests pending use, or refurbishing accommodation for charitable purposes - without incurring ongoing Council Tax during short vacant periods.
Who Qualifies: Registered Charity Definition
To qualify for Class B, the property must be owned by a body that qualifies as a registered charity. In England and Wales, this means:
Charity Commission registration: The organisation must be registered with the Charity Commission for England and Wales. Check registration status at apps.charitycommission.gov.uk. Organisations with income under £5,000/year may be excepted or exempt from registration requirements; their status should be confirmed with the Charity Commission.
Royal Charter bodies: Some major charitable organisations (universities, learned societies, certain Royal Colleges) operate under Royal Charter rather than Charity Commission registration. These can qualify if established for charitable purposes.
Scotland: In Scotland, a charity must be registered with the Office of the Scottish Charity Regulator (OSCR) at oscr.org.uk.
Northern Ireland: Charities registered with the Charity Commission for Northern Ireland may hold properties in England or Wales that qualify for Class B, provided the other eligibility criteria are met.
Not a limited company or trust without charity registration: A community interest company (CIC), a community benefit society, or a private trust that has not achieved registered charity status does not qualify for Class B, even if it operates for charitable-like purposes.
The "Charitable Objects" Requirement
The property must have been last used in pursuance of the charity's charitable objects - meaning the previous use must have directly served the charity's stated purposes.
Examples of qualifying last use:
- Residential accommodation for the charity's beneficiaries (for example, a housing charity's supported accommodation for homeless individuals, now temporarily empty between residents)
- A retreat or residential facility used by a religious charity
- Accommodation for volunteers or missionaries working on the charity's programmes
- A property bequeathed to the charity that was last used as a beneficiary's residence
Examples that may NOT qualify:
- A property purchased by a charity as a commercial investment to generate income (if the investment is incidental to charitable objects rather than in direct pursuit of them)
- A property recently inherited by a charity that was used as a private residence by the donor and has no obvious charitable use planned
- A property used by the charity for storage or administrative purposes rather than direct charitable use
The "last use" test looks at what the property was used for most recently. If the last occupant was a charity beneficiary and the property is now temporarily empty pending the next beneficiary, Class B should apply. If the last use was commercial letting and the property is now empty, Class B does not apply.
The 6-Month Time Limit
Class B is strictly time-limited to 6 months from the date the property became empty. This is not 6 months from the date of application; it is 6 months from the vacancy start date.
If a charity-owned residential property becomes vacant on 1 March 2026, Class B applies from 1 March 2026 and expires on 31 August 2026. From 1 September 2026, full Council Tax resumes - even if the charity has not been able to re-occupy or sell the property.
This time limit creates a genuine financial burden for charities with slow property transaction timescales (for example, where a charitable bequest property requires grant of probate before the charity can take full ownership and decide what to do with it).
Evidence Councils Typically Request
To process a Class B application, your billing council will typically request:
Charity Commission registration documentation: A copy of the charity's registration certificate or a reference to the Charity Commission registration number (which the council can verify online).
Ownership evidence: Land Registry title documents or a solicitor's letter confirming the charity's ownership of the property.
Last use evidence: Documentation of the charitable purpose for which the property was most recently used - occupancy records, tenancy agreements with beneficiaries, or a statement from the charity's property officer explaining the last use.
Statement of current vacancy: Confirmation that the property is currently unoccupied and the date it became vacant.
The Role of Charity Property Officers
Larger registered charities - particularly housing charities, religious organisations, and charitable trusts - frequently manage significant property portfolios. For these organisations, understanding Class B is essential to property portfolio management.
A housing charity that provides supported accommodation for beneficiaries will regularly cycle properties through vacancy periods as one tenancy ends and another begins. Class B provides 6 months of Council Tax relief during these gaps - an important financial protection for organisations often operating on tight budgets.
For property officers at registered charities, the practical workflow for each vacancy should include:
1. Confirm the property is owned by the charity (in the charity's name on the Land Registry title).
2. Confirm the most recent use was in pursuance of the charity's charitable objects.
3. Notify the billing council of the vacancy and apply for Class B immediately.
4. Plan for the post-6-month period: re-occupation, sale, or acceptance of Council Tax liability.
The IRRV (Institute of Revenues, Rating and Valuation) provides professional guidance to billing councils on charity property exemptions, including how to verify Charity Commission registration and the charitable objects requirement.
Impact on Charity Financial Planning
The 6-month Class B window has direct financial planning implications for charities managing residential property:
If a charity cannot re-occupy a property within 6 months of a vacancy, it will face full Council Tax from month 7. In high-rate council areas, this can represent a meaningful cost. Property officers should include post-exemption Council Tax as a scenario in budgeting for any anticipated void period beyond 6 months.
For charities in areas that have adopted the long-term empty premium, the financial exposure escalates further after 12 months total vacancy (100% premium) and again after 5 years (200% premium). The MHCLG tracks premium adoption across English councils.
What Happens at Month 7
When the 6-month Class B exemption expires, full Council Tax becomes payable. The charity as owner becomes the liable person.
Simultaneously, the long-term empty premium clock is running. In councils with the 1-year trigger under the Levelling-up and Regeneration Act 2023, the property may face a 100% long-term empty premium after 12 months total vacancy. A property that was vacant for 1 month before Class B began, Class B for 6 months, and then remains empty for a further 5 months, will reach the 12-month total vacancy threshold.
Charities managing properties in this position should have a plan for the post-Class B period: re-occupancy, sale, or let.
Council Variation in Applying Class B
Most billing councils apply Class B in accordance with the 1992 Order. Some variation exists in:
Evidence standards: Some councils are more relaxed about charity registration proof (accepting a registered charity number alone); others require more detailed documentation.
Interpretation of "charitable objects": Where the last use of a property was not straightforwardly charitable, some councils take a more generous interpretation than others.
Administrative processing time: Some councils process Class B applications faster than others. The exemption should be applied from the date the property became vacant regardless of when the application is processed.
The Appeal Route
If Class B is refused, the appeal route is:
1. Internal review by a senior officer not involved in the original decision.
2. Appeal to the Valuation Tribunal for England (VTE) in England, or the equivalent Welsh or Scottish tribunal.
The VTE considers whether the property meets the statutory criteria. Strong evidence of charitable registration and charitable last use is the key to success.
Frequently Asked Questions
Our charity inherited a bequest property - does Class B apply?
It depends on the last use. If the property was the deceased benefactor's home (private residential use) and the charity has just inherited it, the last use was private residential - not necessarily in pursuance of the charity's objects. Class B may not apply. However, if the charity intends to use the property for charitable purposes and can demonstrate this is in pursuit of its objects, some councils may take a more generous view. Seek specific advice from the billing council.
We're a charitable housing association - does Class B cover our empty properties?
Charitable registered housing associations may qualify for Class B, but the "last use" test is critical. If the most recent tenancy was a social housing tenancy (which is a charitable activity for a registered charitable housing association), Class B should apply for the 6-month period between tenancies. Confirm with your specific billing council.
Does the 6-month limit start from the property becoming empty or from when we apply?
From when the property became empty. If you apply for Class B 2 months after the property became empty, the exemption starts from the vacancy date, not the application date - but you only have 4 months of exemption remaining (6 months total from vacancy date). Apply promptly and provide evidence of the vacancy start date (the date the previous occupant left, tenancy end date, or confirmation from the charity's property records). The billing council will calculate the exemption period from the vacancy start date regardless of when the application is received.
Our charity has more than one empty property - does Class B apply to each one?
Class B applies per property, not per charity. Each individual property owned by the charity that meets the eligibility criteria (empty, last use in pursuance of charitable objects) qualifies separately for its own 6-month exemption window. Multiple properties can qualify simultaneously. Each requires its own application to the relevant billing council. Where a charity has properties in multiple billing authority areas, applications go to each authority separately. The Charity Commission registration is the same for all applications, but the property-specific evidence (last use, vacancy date) must be provided to each council individually.
After Class B expires, can we apply again for the same property?
No. Class B is a once-per-vacancy exemption. Once the 6-month window expires for a particular vacancy, the exemption cannot be restarted for the same vacancy period. If the property is re-occupied and then becomes vacant again (a new vacancy), a fresh 6-month Class B window opens.
