Empty Home Council Tax Exemption 6 Months Wales

The Class C Six-Month Exemption

When a property in Wales becomes both unoccupied and substantially unfurnished, it qualifies for a Class C exemption under the Council Tax (Discounts, Disregards and Exemptions) (Wales) Regulations 2026 (W.S.I. 2026/8). This removes the council tax liability entirely for up to six months from the date the property became empty and unfurnished.

The clock starts on the exact day the last furniture is removed and the property becomes vacant. If you clear out a house on 15 March, the six-month exemption runs from that date. You do not need to wait for the council to inspect — the entitlement exists as a matter of statutory fact, though you will need to notify the council and provide evidence of the vacancy date.

What Happens After Six Months

Once the six-month Class C exemption expires, the property becomes liable for standard council tax at the full band rate. There is no automatic discount for empty properties in Wales beyond the Class C window.

Then, after 12 continuous months of being unoccupied and substantially unfurnished, the property becomes liable for a long-term empty dwelling premium under Section 12A of the Local Government Finance Act 1992. This premium can add up to 300% on top of the standard charge, depending on which council area the property sits in and how long it has been vacant.

The timeline runs like this:

• Months 0–6: Class C exemption — no council tax
• Months 6–12: full standard council tax at the property's band rate
• Month 12 onward: standard council tax plus the empty-home premium

How the Empty-Home Clock Works

The premium clock runs against the property, not the owner. Selling the property, inheriting it, or transferring it to a family member does not reset the 12-month count. A buyer inherits whatever vacancy duration the previous owner accumulated.

There is one important anti-avoidance rule: moving furniture back into the property or allowing someone to stay for less than six weeks does not reset the clock. Welsh legislation explicitly disregards any period of occupation or furnishing lasting under six weeks when calculating continuous empty duration. Only a genuine, continuous reoccupation or return to fully furnished status exceeding six weeks resets the empty-home clock to zero.

This matters for anyone considering a brief refurnishing strategy to reset the premium. Placing a sofa and a bed in the property for three weeks will not work — the council will treat the vacancy as uninterrupted.

Exemptions That Override the Premium

Even after 12 months, certain exemptions can remove the premium entirely:

• Class A (major repairs): if the property requires genuine structural work — roof replacement, foundation underpinning, load-bearing wall rebuilding — it can be exempt for up to 12 months. Wales retained this exemption when England abolished it
• Class E (care move): if the property is empty because the owner moved permanently into a care home or hospital, it is exempt indefinitely
• Class F (probate): exempt from date of death until six months after the grant of probate
• Class 1 (marketed for sale): exempt for up to 12 months if actively marketed at a reasonable price

These exemptions interact with the timeline. A property that has been empty for eight months when the owner moves into care receives Class E exemption from that point — the earlier Class C period and the subsequent standard-rate months are unaffected, but no premium will ever attach while Class E applies.

Notifying the Council

Report the vacancy to the council's revenue department as soon as the property becomes empty. Most Welsh councils have online change-of-circumstances forms. Include the date the property became unoccupied and unfurnished, and any evidence (utility disconnection confirmation, removal company receipt, forwarding address notification).

Claiming the Class C exemption retrospectively is possible — the entitlement exists from the date the conditions were met — but applying promptly avoids billing errors and the administrative burden of requesting a backdated correction.
