Part of: UK Council Tax 2026 — Complete Guide → Council Tax Exemptions 2026 — All 12 Exempt Classes Explained
TL;DR: Class A exemption gives 100% Council Tax relief for properties that are genuinely uninhabitable due to major structural repair works. The exemption lasts up to 6 months (some councils extend to 12 months). It requires genuine uninhabitability - no functioning kitchen, bathroom, heating, or electrics. Cosmetic refurbishment does not qualify. Some English councils have abolished Class A. After it expires, full Council Tax and eventually long-term empty premiums apply.

The Legal Basis for Class A
Class A of the Council Tax (Exempt Dwellings) Order 1992 provides that a dwelling is exempt from Council Tax where it is unoccupied and is "in need of or undergoing major repair work to render it habitable, or is undergoing structural alteration."
This Class was created to recognise that some properties are genuinely uninhabitable during significant renovation - not simply empty, but physically incapable of being lived in due to the works in progress or required. The Local Government Finance Act 1992 provides the enabling power under which the exemption Order was made.
The key terms "major repair work" and "uninhabitable" are not defined in the statute itself. They have been interpreted by billing councils, the IRRV, and Valuation Tribunal decisions into a practical test that most councils apply.
The Uninhabitability Test: What Councils Look For
To qualify for Class A, a property typically needs to be genuinely uninhabitable due to the works. Most councils apply a test that considers whether the property has:
- No functioning kitchen: Kitchen has been stripped out for replacement, plumbing is disconnected, cooking facilities removed.
- No functioning bathroom: Bathroom stripped out for replacement, plumbing disconnected, toilet removed or non-functional.
- No working heating: Boiler removed, radiators stripped, heating system decommissioned during works.
- No working electrics: Rewiring in progress, consumer unit removed, circuits disconnected.
The more of these conditions are simultaneously present, the stronger the Class A claim. A property with all four is clearly uninhabitable. A property with only one (say, a bathroom being replaced while everything else is working) is unlikely to qualify.
What does NOT qualify:
- Decoration throughout (painting, wallpapering, carpet replacement)
- New kitchen installation without structural change (fitting new units while plumbing remains connected)
- Bathroom upgrade (new bath and tiles, old bathroom still functional during the process)
- Rewiring a single circuit while the rest of the house is functional
- Landscaping or garden works
- New central heating boiler replacement (unless the entire heating system is decommissioned during the works)
The IRRV (Institute of Revenues, Rating and Valuation) publishes guidance to billing councils on applying the uninhabitability test, noting that the standard must be genuine uninhabitability - not merely inconvenience.
Structural Alteration vs Major Repair
Class A covers both "major repair work to render it habitable" and "structural alteration." The structural alteration limb can cover properties where the works are not strictly about making the property habitable from uninhabitable, but involve genuine structural changes to the building fabric.
Structural alteration examples that can qualify:
- Removal of load-bearing walls to create open-plan living
- Addition of a new floor or ceiling structure
- Underpinning of foundations
- Substantial roof replacement where interior is exposed
- Conversion between uses (commercial to residential, single house to flats)
Why this matters: A property that is technically habitable but is undergoing significant structural alteration may still qualify for Class A, provided the alteration is genuine and the property is unoccupied during the works.
The Time Limit: 6 to 12 Months
Class A is time-limited. Most billing councils grant the exemption for:
- 6 months initially: The standard period. Applied from the date the works began (or the date the property became uninhabitable, if the works are already ongoing).
- Extension to 12 months: Some councils allow an extension where the works are ongoing and genuinely complex. This is at the council's discretion - there is no statutory right to extend beyond 6 months.
- No extension beyond 12 months: Class A cannot exceed 12 months even in the most complex renovation cases.
A small but significant number of English councils have exercised their discretion (available since the Local Government Finance Act 2012) to abolish Class A entirely from their local scheme. These councils charge full Council Tax during all renovation periods, regardless of the severity of the works. Always check your specific billing council's exemption policy before relying on Class A.
Worked Example: What a Qualifying Renovation Looks Like
To illustrate the distinction between qualifying and non-qualifying works, consider two property scenarios:
Scenario 1 - Qualifying (Class A should apply):
A Victorian terraced house purchased for renovation. The buyer commences a full structural renovation: all internal walls are taken back to brick; floor joists are replaced throughout; the entire plumbing system is disconnected for renewal; the electrical wiring is stripped back; the roof is partially opened for new rafters. The property has no functioning kitchen, bathroom, toilet, heating, or electricity. This is clearly uninhabitable. Class A should apply.
Scenario 2 - Not qualifying:
A 1990s semi-detached house where the owner is fitting a new kitchen and bathroom, redecorating all rooms, and laying new carpets. The kitchen fitters are working for 2 weeks, and the plumber is replacing the bathroom suite over 3 days. During these specific days, one function may be temporarily unavailable, but the property remains broadly habitable. Class A does not apply.
The distinction is genuine uninhabitability (no meaningful ability to live in the property) versus temporary inconvenience during specific tradesperson visits.
The Section 13A Safety Net
Where Class A does not apply - either because the council has abolished it, the works do not reach the uninhabitability threshold, or the time limit has passed - Section 13A of the Local Government Finance Act 1992 provides a potential alternative.
Under Section 13A(1)(c), every billing council has absolute discretion to reduce or remit any Council Tax bill in exceptional circumstances. For genuine renovation projects creating significant financial hardship alongside a Council Tax liability, a Section 13A application is worth pursuing even when Class A is unavailable. The application should document: the nature of the works; why the property is uninhabitable (even if not to the Class A standard); the financial impact of the Council Tax during the renovation; and any other exceptional circumstances.
Evidence Councils Typically Request
To approve a Class A exemption, your billing council will typically request:
Planning permission: If the works required planning consent (usually for structural changes, extensions, or change of use), provide a copy of the planning permission approval. The council can also check the local authority's planning portal.
Building regulations notification or approval: Structural works typically require building control involvement. A building regulations application, notification receipt, or Completion Certificate provides strong evidence.
Contractor agreement or schedule of works: A signed contract with the main contractor showing the scope of works, start date, and projected completion. For self-managed projects without a main contractor, a detailed schedule of works prepared by you or your architect may be accepted.
Photographs: Before-and-after or in-progress photographs showing the state of the property - exposed structural elements, stripped services, uninhabitable conditions.
Site inspection: Some councils send an officer to inspect the property before granting Class A. Cooperation with any inspection request supports the claim.
Council Variation: Which Councils No Longer Offer Class A
Several English councils have abolished Class A from their local empty property exemption scheme. This is permitted under the Local Government Finance Act 2012 and the MHCLG guidance framework, which allows councils to set their own empty property policies.
If your billing council has abolished Class A, you have alternative routes:
Section 13A discretionary relief: Under section 13A(1)(c) of the Local Government Finance Act 1992, every billing council has absolute discretion to reduce or remit any Council Tax bill in cases of exceptional hardship. While not an automatic right, a genuine major renovation creating significant financial pressure alongside the property being genuinely uninhabitable may qualify.
Check the council's specific policy: Contact the revenues team directly and ask for the current policy on empty properties undergoing major renovation. Some councils that have abolished the standard Class A have introduced their own discretionary scheme.
What Happens After Class A Expires
When Class A ends - whether at 6 months, 12 months, or when the works are complete - full Council Tax resumes from the day after the exemption period ends.
Additionally, the long-term empty premium clock continues. In councils that have adopted the 1-year trigger under the Levelling-up and Regeneration Act 2023, a 100% premium may apply once the total vacancy (including any Class A period) reaches 12 months. This creates a financial incentive to complete renovation works within the Class A window and promptly re-occupy or let the property.
Executors and property investors who rely on Class A to shelter a property during works should plan the works timeline to complete within the exemption period or accept the post-Class A Council Tax liability.
The Appeal Route
If your Class A application is refused - either because the council says the works do not meet the uninhabitability standard, or because the council has a local policy excluding Class A - you can:
1. Request an internal review by a senior officer, providing additional evidence of the structural nature of the works.
2. If the internal review fails, appeal to the Valuation Tribunal for England (VTE) in England (the equivalent in Wales or Scotland).
The VTE considers whether the property meets the statutory criteria. Prepare detailed photographic evidence and contractor documentation for the tribunal.
Frequently Asked Questions
My kitchen is being completely replaced - does Class A apply?
Fitting a new kitchen does not, by itself, make a property uninhabitable. If the plumbing is reconnected and a temporary cooking facility exists during the replacement, the property is habitable. If the entire kitchen plumbing is disconnected and the room is completely stripped back to bare walls with no cooking or washing-up facilities, the uninhabitability argument is stronger.
I'm doing a full gut renovation - Class A seems obviously applicable, but my council refused. What can I do?
Request an internal review. Provide photographs showing the state of the property (bare plaster walls, stripped services, no bathroom or kitchen), building regulations documentation, and a contractor's schedule. If the review fails, appeal to the Valuation Tribunal for England. Well-evidenced gut renovation claims typically succeed on appeal where the council's initial refusal was based on insufficiently detailed examination of the evidence.
Does Class A apply from the date I bought the property or the date works started?
Class A applies from the date the property became uninhabitable due to works - typically the date works commenced (if the property was habitable before works started) or the purchase date (if the property was uninhabitable at purchase, for example a derelict property). Provide evidence of the works start date.
Can I live in one room of the property while doing major works in the rest?
No. If you are occupying any part of the property as your residence, the property is not "unoccupied" for Class A purposes. Class A requires the property to be entirely unoccupied during the works. If any area is habitable and occupied, Class A does not apply to the whole property.
My council says they'll give me a 6-month exemption but the works will take 12 months. What do I do?
Apply for the 6-month exemption initially. Toward the end of the 6 months, contact the revenues team before the exemption expires and request an extension for the additional time the works will take. Provide updated evidence of works in progress. The extension (if the council offers it) typically runs for up to 6 additional months.
How we verified this
Class A exemption is from the Council Tax (Exempt Dwellings) Order 1992. The uninhabitability standard is derived from MHCLG guidance on Class A administration and IRRV practitioner guidance. The Section 13A alternative is from Local Government Finance Act 1992 s13A(1)(c). The council variation (some councils abolishing Class A) is permitted under the Local Government Finance Act 2012. The long-term empty premium interaction is from the Levelling-up and Regeneration Act 2023. The Valuation Tribunal appeal route is from the Council Tax (Alteration of Lists and Appeals) (England) Regulations 2009.
