Selling an Empty House and Council Tax Premium

The Premium Does Not Pause Because You Are Selling

Putting your empty property on the market does not automatically stop the empty home premium. The surcharge runs by default once the property hits 12 months of continuous vacancy, whether you are actively trying to sell or not. You need to apply for the Class G exception — it is not applied automatically.

Many property owners discover this only when the premium appears on their demand notice, having assumed their estate agent's "For Sale" board would be enough.

Applying for the Class G Marketing Exception

Class G protects empty properties that are genuinely marketed for sale at a reasonable price. You apply to your billing authority with supporting evidence:

• A signed estate agency instruction (or demonstrable private marketing)
• Live portal listings on Rightmove, Zoopla, or OnTheMarket
• A current Energy Performance Certificate
• An asking price that sits within a reasonable range of local comparable sales

The exception lasts up to 12 months from when genuine marketing began. During this window, you pay the standard council tax charge but no premium.

What Happens When the Market Is Slow

If the property does not sell within 12 months of marketing, the Class G exception expires. The premium then applies immediately, calculated from the total empty duration — not from when the exception ended.

You cannot simply relist and claim Class G again. A new 12-month exception requires a genuine arm's-length sale to have occurred (a "relevant transaction" that actually transfers ownership). This means you cannot cycle through consecutive exception periods without the property changing hands.

If the property has not sold and you face the premium, your realistic options are:

• Reduce the asking price. If the council considered the original price unreasonable, the exception may not have been valid anyway
• Switch to letting. A Class H (marketed for let) exception offers another 12-month window if you can market the property for rent instead
• Apply for Section 13A hardship relief if exceptional circumstances apply

Conveyancing Delays and Chain Collapses

A sale that is agreed but not yet completed does not end the premium liability. You remain the owner and the liable person until legal completion. If the chain collapses or the buyer's mortgage falls through, the empty clock continues from where it was.

Conveyancing in England routinely takes three to six months. For vendors who are already approaching the 12-month threshold when they accept an offer, a collapsed chain can push them past the point where Class G protection runs out.

There is no exception or exemption for conveyancing delays specifically. Your cover is the Class G marketing exception, which applies while the property is genuinely being marketed — being under offer still counts as actively marketed, provided the property remains listed and your agent is still instructed.

The Premium Liability Transfers on Completion

When the sale completes, the empty period accumulated under your ownership transfers to the buyer. If they plan to occupy the property, the clock resets after more than six continuous weeks of genuine occupation. If they are purchasing to renovate or as an investment, they inherit the full empty duration and may face the premium from day one unless another statutory exception or local relief applies; there is no general national new-owner exception.

Make sure your solicitor's completion statement correctly apportions council tax liability up to the completion date. Disputes over council tax apportionment between buyer and seller are surprisingly common and can take months to resolve.
