If you own a property that's sitting empty right now — an inherited house, a landlord's vacant unit between tenants, a home you moved out of before it sold — there's a good chance your council tax bill has already doubled, or is about to. And the estate agent "sale in progress" sign in the window won't stop the clock for long.

The Premium Most Owners Don't See Coming

Since April 2024, English councils have had the power to charge a premium on any home that has stood empty and substantially unfurnished for a continuous period of just one year — down from the two-year threshold that applied before. Government guidance confirms the maximum premiums councils can apply on a stepped basis:

In plain terms, a property empty for just over a year can already be costing its owner double the normal council tax bill — and that's before any second-homes premium, which a separate set of rules allows councils to apply to furnished-but-unoccupied homes from day one, with roughly 84% of English billing authorities now charging it, according to Hamptons data.

None of this is a fringe policy a handful of councils are experimenting with. It is now the default, widely-adopted position across England, and it applies whether the property is empty because it's mid-sale, mid-probate, mid-renovation, or simply between tenants for longer than planned.

"But I'm Actively Trying to Sell It" — Here's the Catch

There is an exception. A property being actively marketed for sale or let is excepted from the empty-homes premium — but only for 12 months, and only for as long as the council is satisfied the marketing is genuine. That means listed at a realistic price, properly advertised, with a valid Energy Performance Certificate, and with the owner able to show they're taking real steps to sell — not just a board outside a house that's quietly been taken off the priority list.

Once that 12-month exception runs out, or once a council decides the marketing isn't genuinely active, the premium clock starts running — retroactively from when the property first became empty, not from when the exception ends.

This is exactly where the traditional estate agent model does owners the most damage. A property that lingers on the market for months through slow viewings, chain collapses and price reductions isn't just losing money on a falling asking price — it is quietly burning through the one exemption that was protecting the owner from a council tax bill that doubles or triples.

The Real Numbers Behind "Just Wait for the Right Buyer"

New data shows 44% of homes listed in England between 2023 and 2026 failed to find a buyer at all, and roughly a quarter of agreed sales now collapse before completion. Add those figures to a 12-month marketing exception and a council tax premium waiting on the other side of it, and "just be patient and hold out for the right offer" stops looking like sound advice and starts looking like an expensive gamble with a deadline attached.

What Owners of Empty Properties Should Actually Check

How long has it genuinely been empty? Not "roughly" — the actual date matters, because it's when the premium clock starts, not when you eventually decide to deal with it.

Is your council one of the majority now charging the maximum premium? Most are. Contact your local authority directly and ask what determination they've made and at what rate — don't assume your bill hasn't changed.

Are you still inside your 12-month marketing exception — and can you prove it? If a council later queries whether marketing was genuinely active, the burden is on the owner to demonstrate it, not the other way round.

What happens if it doesn't sell in time? This is the question a traditional estate agent relationship rarely forces anyone to confront until the bill arrives.

The Faster Route Off the Clock

A cash sale removes the variable that actually causes this problem: time. There's no chain to collapse, no repeat round of viewings, no months ticking past while a council tax exception quietly expires in the background. If a property has already been empty for a while — or you can see it's heading that way — selling for cash before the premium clock does real damage is very often the more financially sound decision, not the "distress sale" it's sometimes made out to be.

Frequently Asked Questions

How long can a property be empty before council tax doubles?
Under current rules, councils can apply a premium once a home has been empty and substantially unfurnished for a continuous period of one year. Many councils charge the maximum 100% premium at that point, effectively doubling the standard bill.
Does putting a property up for sale stop the premium?
It can, but only for up to 12 months, and only while the council is satisfied the property is being genuinely and actively marketed at a realistic price. Once that window closes, or if the marketing isn't judged to be genuine, the premium applies retroactively from when the property first became empty.
Is the council tax premium the same everywhere in England?
No. The premium is discretionary, so each council decides whether to charge it and at what rate up to the statutory maximum. However, the large majority of English billing authorities have now adopted a premium, so assuming a property is exempt is a risky assumption to make.
