Buying an Empty Property: Council Tax Premium Rules

Buying a Long-Term Empty Property Carries the Premium Clock

When you purchase a property in England that has been empty for over 12 months, the premium clock does not reset on completion. Under Section 11B of the Local Government Finance Act 1992, the empty period attaches to the dwelling, not the owner. The accumulated vacancy carries over to you.

This catches many buyers off guard. If the council charges a premium and no exception applies, a property that has been empty for 11 months can become liable after just one additional month in your hands.

There Is No General New-Owner Exception

There is no general national statutory exception solely because a new owner acquires a long-term empty property. Purchase alone does not pause or reset the empty clock, so if the property has already reached a premium threshold, the premium may apply from the start of your ownership unless another exception applies.

The billing authority may have local relief or exclusions, so ask the council what applies to the property. The statutory classes that may be relevant include active marketing for sale or let, major structural repairs, and qualifying probate cases; each has its own conditions and time limit.

What to Check Before Completion

Do not assume there is a six-month grace period. If the property is still empty and unfurnished and has already crossed the applicable threshold, the premium may apply immediately unless an exception or local relief applies.

Your practical options include:

• Move in — if the property is habitable, genuinely occupying it for more than six continuous weeks resets the empty clock
• Begin renovation — if the property needs structural work, apply for the Class M major repairs exception to extend premium protection for up to 12 months
• Market the property for sale or let — apply for the Class G or Class H exception if you plan to sell or rent rather than occupy

Each of these routes has its own evidence requirements and time limits. Check the council tax record and the relevant exception conditions before relying on a change of ownership to affect the bill.

During Conveyancing: Check the Empty Period

Before exchanging contracts on a property that looks like it has been empty for a while, ask the billing authority for the exact date the dwelling was classified as unoccupied and substantially unfurnished. Request the current accumulated empty duration on the council tax register and whether any exemptions or exceptions are currently active.

This information should form part of your pre-purchase due diligence alongside the standard property searches. Your solicitor can request it from the council.
