TL;DR: Properties undergoing major structural renovation that makes them uninhabitable may qualify for Class A Council Tax exemption under the Council Tax (Exempt Dwellings) Order 1992. The exemption typically runs for 6 months (some councils extend to 12 months). Cosmetic refurbishment - new kitchen, carpets, decoration - does not qualify. After Class A expires, full Council Tax resumes and the long-term empty premium clock continues running.

What Class A Exemption Covers
The Class A exemption under the Council Tax (Exempt Dwellings) Order 1992 provides complete relief from Council Tax for properties that are:
- Unoccupied, and
- Requiring or undergoing major repair work to render them habitable, or undergoing structural alteration
Both conditions must be met. A property that is merely empty without any works in progress or required does not qualify for Class A - it would be a straightforward empty property liable for the full Council Tax charge.
The key concept is "uninhabitable due to major works." The Local Government Finance Act 1992 establishes the broader framework within which the Order operates. The MHCLG publishes guidance to councils on how to apply Class A consistently.
The Standard for "Uninhabitable Due to Major Works"
Class A is not triggered by any building work. The property must be in a condition that prevents normal habitation due to the nature of the works. Indicators that typically satisfy the standard:
Works that commonly qualify:
- Full structural renovation where load-bearing walls, roof structure, or foundations are being altered
- Complete rewiring requiring the property to be de-energised throughout
- Complete replumbing requiring removal of all sanitary facilities and kitchen plumbing
- Removal of all internal walls or floors as part of a reconfiguration
- Post-fire or post-flood restoration where the damage has rendered the property uninhabitable
- Properties affected by subsidence requiring structural underpinning works
Works that typically do not qualify:
- Fitting a new kitchen or bathroom (replacing like-for-like without structural change)
- Redecoration throughout (painting, wallpaper, carpet replacement)
- Installing a new central heating system without wider structural works
- Garden landscaping
- External rendering or repointing
- Window replacement without structural alteration
The test is whether the property could reasonably be occupied during the works. A property having its roof replaced but otherwise complete would typically not meet the uninhabitable standard (people live in houses while the roof is being repaired). A property where the roof is removed, the floor joists are replaced, and all services are disconnected would typically meet the standard.
The Exemption Period: 6 to 12 Months
The Class A exemption is time-limited:
Standard period: 6 months at council discretion. Most billing councils grant 6-month Class A exemptions for qualifying properties.
Extended period: Some billing councils allow extensions to 12 months where works are ongoing and genuinely complex. This is at the council's discretion - there is no statutory right to a 12-month exemption.
No extension beyond 12 months: Even in the most complex renovation cases, Class A does not extend beyond 12 months under the current exemption framework. After 12 months, full Council Tax is payable regardless of whether works are complete.
Practical implication: If your renovation is genuinely expected to take longer than 12 months, build the post-exemption Council Tax cost into your project budget from the start.
Evidence Councils Typically Request
To claim Class A, you will need to provide the billing council with evidence that the works genuinely render the property uninhabitable. Common evidence:
Planning permission: If the works required planning permission (typically for structural changes or change of use), provide a copy of the approval. Planning permission evidences the structural nature of the works.
Building regulations approval or notification: For works requiring building control involvement (structural alterations, electrical rewiring, plumbing works), provide the building regulations application or notification receipt.
Contractor agreement or schedule of works: A signed contract with the main contractor showing the scope of works and projected timeline. For owner-managed projects, a detailed schedule of works may be accepted.
Photographs: Before-and-after photographs showing the state of the property. Photos of exposed structural elements, disconnected services, or uninhabitable conditions are particularly helpful.
Council inspection: Some councils send an officer to inspect the property before granting Class A. Cooperation with any inspection request is in your interest.
Council Variation: Which Councils Have Abolished Class A?
The Class A exemption is established in the Council Tax (Exempt Dwellings) Order 1992, but billing authorities have been given discretion to modify or remove some exemptions locally. Some English councils have used this discretion to offer reduced discounts rather than full exemptions during renovation:
- Some councils offer a 100% exemption for the first 6 months (the standard Class A position).
- Some offer a 50% discount rather than a full exemption.
- A small number have replaced Class A with no discount at all, charging full Council Tax during renovation.
Check your specific billing council's adopted policy. This cannot be assumed from the national standard - call the revenues team or check the council's published exemption policy.
After Class A Expires: The Premium Clock
When Class A ends, full Council Tax resumes. Importantly:
The long-term empty premium clock continues running during and after the Class A period. Class A pauses the premium payment but may not necessarily pause the vacancy period count for premium threshold purposes. Check with your billing council whether the Class A period resets or pauses the long-term empty clock.
If the property has been vacant for a total of 12 months (including any Class A period), and your council has adopted the 1-year premium trigger under the Levelling-up and Regeneration Act 2023, a 100% premium may apply immediately after Class A expires.
Renovation During a Buy-to-Let Void Period
For buy-to-let landlords undertaking major works between tenancies, Class A can provide a critical cost reduction. A void period that would otherwise attract full Council Tax from day one becomes a zero-liability period during the Class A exemption.
The practical sequence for a landlord with a property undergoing substantial renovation between tenancies:
1. Previous tenant departs.
2. Landlord commences substantive structural works immediately (ensuring genuine uninhabitability is documented from the start).
3. Landlord notifies the billing council and applies for Class A with evidence of works.
4. Class A runs for up to 6 months (12 months if the council grants an extension).
5. Works complete; new tenancy begins; Class A ends; the incoming tenant becomes liable.
If the Class A period expires before works are complete, full Council Tax resumes. The long-term empty premium clock then continues toward the 1-year total vacancy threshold. For landlords in councils that have adopted the 1-year premium trigger, planning the works timeline to complete within the Class A window is financially important.
The Section 13A Alternative
Where Class A does not apply (perhaps because the works do not meet the "uninhabitable" standard), some renovation-related hardship cases may be eligible for Section 13A(1)(c) discretionary relief under the Local Government Finance Act 1992. Section 13A gives every billing authority absolute discretion to reduce or remit a Council Tax bill where exceptional circumstances apply.
For a property where a genuine renovation-related hardship exists (for example, a fire has made the property uninhabitable but the works are too far along for Class A to be freshly granted), applying for Section 13A relief is worth pursuing alongside or instead of Class A.
Frequently Asked Questions
My kitchen fitter is coming next week - does this qualify for Class A?
Fitting a new kitchen does not, by itself, render a property uninhabitable and does not qualify for Class A. You would need to be undertaking major structural works that genuinely prevent occupation. A new kitchen installation is typically cosmetic in nature. Council Tax remains payable during kitchen fitting.
I bought a fire-damaged property - can I claim Class A from purchase?
Yes. A fire-damaged property that is genuinely uninhabitable due to structural fire damage can qualify for Class A from the date you become the liable person (purchase completion date). Provide photographs, loss adjuster's report (if available), and any remediation contractor's schedule to the billing council. The exemption runs for 6 months from the date it is granted, extendable to 12 months at the council's discretion.
The council refused Class A but my property genuinely can't be lived in - what can I do?
Request an internal review, providing additional evidence (photographs, engineer's report, contractor confirmation that the property is uninhabitable). If the review fails, appeal to the Valuation Tribunal for England. Alternatively, apply for Section 13A discretionary relief and describe the exceptional circumstances.
Can I live in part of the property while renovating another part and still claim Class A?
No. If any part of the property is occupied as a main or sole residence, the property is not "unoccupied" for Class A purposes. Class A requires the property to be entirely unoccupied due to the works.
Does Class A apply to a commercial property I'm converting to residential?
Class A covers dwellings undergoing structural alteration. A property being converted from commercial to residential use may or may not be classified as a dwelling for Council Tax purposes during the conversion period - this depends on how far advanced the conversion is and whether the Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) has yet assigned a Council Tax band. Contact the billing council and the Valuation Office for guidance on the specific conversion scenario.
How we verified this
Class A exemption is from the Council Tax (Exempt Dwellings) Order 1992. The standard for "uninhabitable due to major works" is derived from MHCLG guidance on Class A administration. Section 13A discretionary relief basis is Local Government Finance Act 1992 s13A. The Levelling-up and Regeneration Act 2023 provisions on the premium clock interaction are from MHCLG's published guidance accompanying the Act. IRRV provides professional guidance on exemption administration to billing councils.
