Furnished vs Unfurnished Council Tax Premium: Which Regime Applies

Why Furniture Matters So Much

English council tax treats empty properties through two entirely different regimes depending on one question: is the property substantially furnished?

Furnished and unoccupied → Section 11C second home premium (up to 100% extra, applied from day one if the council has adopted it).

Unfurnished and unoccupied → Section 11B long-term empty premium (up to 100% extra after 1 year empty, escalating to 200% after 5 years and 300% after 10 years).

Getting the classification wrong — or not realising you are in the wrong category — can cost thousands of pounds a year. Councils are not obliged to tell you which regime you fall under or suggest switching.

What "Substantially Furnished" Means

The legislation does not give a room-by-room inventory. "Substantially furnished" is a factual question assessed by the billing authority based on what is in the property. There is no fixed threshold like "three items of furniture."

In practice, councils look at whether the property could be lived in. A bed, sofa, and kitchen equipment in place will typically make a property substantially furnished. A property with only a few items in storage — boxes stacked in a garage, an old wardrobe in a spare room — may not.

The grey area is real, and councils vary. Some operate a checklist approach internally; others rely on inspection officers. If you are near the boundary, document the contents with photographs and keep a written record of what was removed and when.

When Removing Furniture Helps (and When It Doesn't)

If your council charges the second home premium and your property has been empty for less than a year, stripping the furniture converts it from a Section 11C second home to a standard unoccupied dwelling with no premium until the 12-month empty-home clock starts ticking.

But if the property has already been unoccupied for over 12 months, removing the furniture shifts it from the second home premium to the long-term empty premium — which may be the same rate (100%) or higher. The Section 11B clock attaches to the dwelling, not the owner, so the empty-home clock keeps running regardless of who owns the property or what furniture is inside.

Landlords between tenants face a specific version of this trade-off. Keeping a rental property furnished during a void triggers the second home premium immediately but can qualify for the Class H letting exception (12-month cap) while you market it. Stripping it may shift the property to the empty-home regime, but Class H can also apply to an unfurnished empty home that is actively marketed for let on reasonable commercial terms.

Second Home vs Empty Home: Side by Side

The second home premium (Section 11C) has no clock — it applies from day one if the property is furnished and unoccupied and the council has adopted the premium. The maximum surcharge is 100%.

The empty home premium (Section 11B) has a graduated clock: nothing for the first year, up to 100% extra from year one to five, up to 200% from five to ten, and up to 300% above ten years. The clock attaches to the dwelling, meaning a buyer inherits it.

Both regimes carry exceptions under SI 2024/1007. Classes E through L cover second homes; some also cover empty homes. Class M (major repairs) applies to empty homes only — a common trip-up for owners who furnish a property while renovating.
