Selling an Empty House in the UK: The Full 2026 Cost Guide

By Lisa Hayes · 16 August 2026

If your house has been standing empty for close to a year, the clock that matters most isn't the property market. It's your council tax account. Since April 2024, councils in England can charge a premium once a home has been unoccupied and substantially unfurnished for just 12 months, taking your bill to double the standard charge, rising to four times the standard charge once a property has sat empty for a decade.

There is a way out, and almost nobody tells sellers about it: a mandatory 12-month exception for homes that are genuinely being marketed for sale. But you only get to use it once per property, per owner. Burn it by listing at a fantasy price for a year and you don't get a second go.

This guide covers what an empty house actually costs you each month, which exceptions you can claim, why your buildings insurance may already be worthless, and the three realistic ways to sell.

What counts as an "empty" house for council tax?

The legal test is narrower than most people assume, and the wording matters. Under section 11B of the Local Government Finance Act 1992, a long-term empty dwelling is one that is both unoccupied and substantially unfurnished for a continuous period of at least one year.

Both limbs have to be satisfied. A furnished house that nobody lives in isn't a long-term empty home at all. It's a "dwelling occupied periodically" under section 11C, which most people call a second home, and since April 2025 that attracts its own premium of up to 100%. So leaving the sofa and beds in place doesn't dodge the charge in most areas. It just moves you into a different bracket.

The government has never published a hard definition of "substantially unfurnished". In practice councils look for the basic items needed for day-to-day living: somewhere to sleep, somewhere to sit, somewhere to keep clothes. A house stripped back to bare boards with a fridge left behind is empty. A fully furnished house with the utilities on is not.

The six-week reset rule

Here's the detail that trips people up. To reset the clock, the dwelling must be occupied, or substantially furnished, for a continuous period of at least six weeks. A weekend visit does nothing. A nephew staying for a fortnight while he decorates does nothing. Six unbroken weeks, or the counter keeps running from the day it first became empty.

And note what the guidance says about exemptions: if a dwelling was exempt and then stops being exempt, the empty-home clock starts from when the dwelling first became empty, not from when the exemption ended. That catches a lot of executors out.

How much extra council tax will you actually pay?

Councils choose whether to charge a premium and at what level, up to the statutory ceiling. They can also take a stepped approach, so a council might charge 50% between one and two years and 100% from two to five.

The £2,000 column is an illustration, not a national average. Check your own band and your own council's determination, because the variation between neighbouring authorities is enormous and entirely legal.

Scale matters here too. MHCLG's Council Taxbase 2025 figures, analysed by the Empty Homes Network, recorded 303,185 dwellings in England empty for more than six months in 2025 — about 1.2% of all homes, and a 14% rise on the previous year. Add second homes and exempt unoccupied properties and more than a million English dwellings aren't in permanent use. Councils have noticed. That is precisely why the premium was tightened.

Watch the definitions when you read headlines about this: the statistical "long-term empty" count uses a six-month threshold, while the premium uses twelve months. They are not the same number and journalists routinely conflate them.

The 12-month exception almost nobody claims

The Council Tax (Prescribed Classes of Dwellings and Consequential Amendments) (England) Regulations 2024 created nine mandatory exceptions. Councils cannot disapply them. The one that matters most if you're reading this is Class G: dwellings being actively marketed for sale, which shields you from the premium for up to 12 months.

That single rule should change how you approach the sale. If you list at 15% above what the house is worth, spend nine months quietly discovering the market disagrees with you, then reduce and finally sell in month fourteen, you have spent your exception and you're paying the premium anyway. Price it to sell on day one or don't start the clock at all.

Councils assess "actively marketed" holistically. The published guidance points to factors including whether the dwelling is clearly advertised, whether it is marketed at a fair market value, whether there are artificial barriers preventing a sale, whether there's a valid EPC, and whether the owner is taking other reasonable steps. A listing with no photographs, no viewings permitted and a price nobody will pay is not active marketing, and a competent revenues officer will say so.

Two practical points. First, the exception can cover a period before your council introduced the premium, so if you were already on the market you may be entitled to more than you think. Second, at the end of the 12 months the council has discretionary power under section 13A of the 1992 Act to extend relief where circumstances warrant it. Ask. The worst answer is no.

Which other exceptions might apply to you?

Class M deserves a closer look if the property is in poor condition. It covers empty dwellings requiring or undergoing major repairs or structural alterations, for up to 12 months. If the work finishes early, the exception still runs for a further six months or until the 12 months are up, whichever comes first. Like Class G, you get one bite unless the property changes hands. Redecorating and a new bathroom won't qualify. Re-roofing, underpinning, rewiring a gutted house or removing structural walls will.

Class M and Class G can run in succession where the property qualifies for each in turn. Renovate for a year under M, then market for a year under G, and you can legitimately hold the premium off for two years while you sort the house out. That is a real planning opportunity and I've almost never seen it explained to a seller by anyone.

What if you inherited the house?

Inherited homes get the most generous treatment, and they need it, because probate is slow.

Under the Council Tax (Exempt Dwellings) Order 1992, a property left empty after the owner's death is completely exempt from council tax — not just the premium, the whole bill — for as long as it stays unoccupied and until probate or letters of administration are granted. After the grant, a further six months of full exemption is possible, provided the home stays empty and hasn't been transferred to beneficiaries or sold.

Then Class I takes over. It gives a 12-month exception to the premium running from the date of the grant, concurrent with that six-month exemption. In plain terms: unlimited relief while probate drags on, full exemption for six months after the grant, then premium protection for another six.

Twelve months from the grant sounds generous until you've actually administered an estate with three beneficiaries who don't agree. If that's your situation, read our guide on whether you can sell before probate is granted, and our practical walkthrough of selling an inherited property. The single biggest cost in a probate sale is usually not the estate agent. It is the months of carrying costs while everyone decides.

Do the same rules apply in Wales, Scotland and Northern Ireland?

No, and this catches people with property across the border. The MHCLG guidance applies to England only.

• Wales has allowed councils to charge premiums of up to 300% on long-term empty homes and second homes since April 2023, and several authorities have used the full ceiling. Welsh premiums have been the most aggressive in the UK for some time.
• Scotland operates its own regime under Scottish legislation, with councils able to charge up to a 100% increase on long-term empty homes and, since April 2024, on second homes.
• Northern Ireland uses domestic rates rather than council tax, with a different set of rules on empty properties entirely.

If your empty property is in Wales or Scotland, go straight to that council's own published policy. Don't rely on English guidance, and don't rely on a comparison article written for a English audience — including the tables above.

Is your buildings insurance already void?

This is the risk that actually loses people money, and it is far more urgent than the tax.

Virtually every standard UK home insurance policy contains an unoccupancy clause. Once the property has been empty for a defined number of consecutive days — commonly 30 to 60, depending on the insurer — cover is either stripped back to a bare minimum or withdrawn for the perils that actually happen to empty houses. The typical reduced cover is fire, lightning, explosion, earthquake and aircraft. Everything else goes.

Look at what falls outside that bare-minimum cover: escape of water, theft, vandalism and malicious damage. A burst pipe in an unheated empty house in February is the single most common serious claim on a vacant property, and it is exactly the peril your policy has stopped covering. I have seen a £40,000 water damage bill land on an executor who thought the house was insured because the direct debit was still going out.

Do this today, not next month:

1. Tell your existing insurer the property is unoccupied. In writing. Non-disclosure is what voids policies, not the vacancy itself.
2. Move to a specialist unoccupied property policy if the current insurer won't extend cover. They exist precisely for probate, renovation and homes awaiting sale.
3. Read the conditions properly. Most require documented inspections every 7 to 14 days, minimum security standards, and winter precautions — either heating left on at a low constant temperature or the system fully drained down.
4. Keep the inspection record. A dated log with photographs is what turns a disputed claim into a paid one.

Unoccupied cover costs more than standard home insurance, sometimes considerably more. It is still the cheapest line item in this entire article.

What else does an empty house quietly cost?

The council tax premium is the visible number. The rest add up faster.

• Standing charges. Gas and electricity standing charges accrue whether or not you use a unit of energy. Don't disconnect the supply, though — a house with no power is harder to view, harder to survey and harder to insure.
• Heating. Leaving low heat on through winter costs money. Repairing burst pipes costs a great deal more, and your insurer may require it anyway.
• Garden and frontage. An overgrown front garden is a signal to every opportunist on the street, and it knocks thousands off perceived value before a buyer has stepped through the door.
• Deterioration. Empty houses decline fast. Damp arrives because nobody's ventilating, seals perish, and small leaks run for months undetected. If damp has already taken hold, our guide to selling a house with damp sets out what buyers and surveyors will do with it.
• Security. Squatting in a residential building has been a criminal offence in England and Wales since section 144 of the Legal Aid, Sentencing and Punishment of Offenders Act 2012, which helps. Removing squatters is still slow, expensive and deeply unpleasant.
• Mortgage terms. If there's still a mortgage on the property, check the conditions. Many lenders require notification once a property is unoccupied for an extended period.

Can the council take the house off you?

Not easily, but the powers exist and it's worth knowing where the edges are.

Empty Dwelling Management Orders under Part 4 of the Housing Act 2004 let a council take over management of a long-term empty home, carry out works and place tenants in it. Ownership doesn't transfer, and the rent is used to cover the council's costs. An interim EDMO normally runs 12 months; a final EDMO can last up to seven years. The threshold and the approval process were tightened in 2012, and in practice EDMOs are rare — councils have to satisfy a tribunal and demonstrate community support, which is a high bar.

Compulsory purchase is the sharper end. Councils can use CPO powers on long-term empty homes to bring them back into use, and some authorities do so as part of a published empty homes strategy. It is slow and legally involved, but it is not theoretical. We cover the process in our guide to selling under a compulsory purchase order.

Realistically, the far more likely outcome is a letter from an Empty Property Officer offering help — grants, loans, matching you with a private landlord scheme. Answer it. Those officers can be genuinely useful, and engaging with them is also good evidence if you later ask for discretionary relief.

The one genuine financial upside: 5% VAT

If the property has not been lived in during the two years immediately before work starts, renovation and alteration work supplied by a VAT-registered contractor can be charged at the reduced rate of 5% instead of 20%, under the empty residential premises rules in VAT Notice 708.

On £50,000 of work that is £2,500 of VAT rather than £10,000. A £7,500 swing.

Three conditions to watch. The contractor has to supply the materials as part of their service — buy the kitchen yourself and you pay 20% on it. You need evidence the property was genuinely empty, and HMRC accepts council tax records, electoral roll data, utility company records and confirmation from the council's Empty Property Officer. And once the two-year clock is satisfied, all the qualifying work is reduced-rated even if someone moves in partway through.

Get the Empty Property Officer's confirmation letter before the contractor invoices you. Retrospective evidence is a much harder conversation.

Should you renovate the house or sell it as it stands?

I get asked this every week, and the honest answer is that most people over-invest.

Run the arithmetic properly. Take the realistic uplift in sale price, subtract the full cost of the work, subtract the extra months of council tax premium, insurance, standing charges and finance, then subtract the risk that the work overruns — because it will. Kitchens and bathrooms in a tired house usually return less than they cost once you count the carrying costs. Fixing something that makes the house unmortgageable is different, because that changes the buyer pool from cash-only to everyone.

So the test isn't "will this look nicer". It's "does this move the property from one buyer category to another". A failed electrical installation, an unsafe roof, structural movement, no functioning kitchen or bathroom, or serious damp will all push lenders away. Cosmetic tiredness will not. If you're unsure which side of the line you're on, our guide to selling an unmortgageable house and our page on selling an unsellable house spell out what lenders actually refuse.

If the property is structurally sound but dated, selling as is is usually the better call. Renovation is a business, and you probably aren't in it.

What are the three ways to sell an empty house?

The open market gives you the best headline price and the least certainty. That's the trade. If you go this route, get the property on within days rather than months so the Class G clock and the marketing period overlap, and price it against genuine comparable sold prices rather than the optimistic valuation the agent quoted to win your instruction. Our guide to what your house is actually worth covers how to sanity-check that number yourself.

Auction suits properties the mortgage market struggles with, and it puts a hard date in the diary. But entry fees are payable whether or not it sells, reserves get missed, and a poorly-attended lot can go for a lot less than you hoped.

A genuine cash buyer is the right answer more often for empty houses than for occupied ones, purely because your holding costs are running. If you're paying a 100% council tax premium, unoccupied insurance, standing charges and heating on a house you're not using, six extra months on the open market can quietly erase the price advantage. That is arithmetic, not a sales pitch.

What matters is that the buyer is real. Ask for proof of funds up front, insist the offer is not subject to a survey-stage renegotiation, refuse any tie-in agreement, and check the company against our review of the best house buying companies. A firm that offers 85% and then drops to 70% a fortnight before completion has cost you more than one that offered 78% and honoured it. That bait-and-switch is the single most common complaint in this industry, and it is entirely avoidable if you compare offers rather than accepting the first one.

Should you stage an empty house or leave it bare?

Empty rooms photograph badly and feel smaller than they are. Buyers are poor at judging scale without furniture, and they fixate on flaws when there's nothing else to look at — every scuff on the skirting, every patch on the ceiling.

You don't need full staging. What actually moves the needle on an empty house is cheap and unglamorous:

1. Clean it properly, including the windows. Light does more for an empty room than furniture does.
2. Cut the grass and clear the frontage. Kerb appeal decides whether people get out of the car.
3. Deal with the smell. Empty houses smell stale. Air it thoroughly the day before every viewing.
4. Get the heating on for viewings in winter. A cold house feels like a problem house.
5. Redirect the post and clear the doormat. A heap of mail behind the door tells buyers and burglars the same story.
6. Fit a couple of cheap lamps and timer switches. Security and warmth, for the price of a takeaway.

Skip the expensive virtual staging. UK buyers have got wise to it, and a photo that doesn't match the room breeds distrust at exactly the moment you need it least.

Mistakes I see over and over

• Assuming the premium starts at two years. It changed in April 2024. Plenty of advice online is still out of date.
• Not telling the insurer. The vacancy doesn't void the policy. The non-disclosure does.
• Wasting Class G on an overpriced listing. One use per owner. Spend it on a price that will actually sell.
• A fortnight's stay to "reset" the clock. It's six continuous weeks, occupied or substantially furnished, or nothing.
• Never asking about discretionary relief. Section 13A powers exist and councils do use them. You have to ask.
• Renovating to sell. Fix what stops a mortgage. Leave the rest to the buyer.
• Taking the first quick-sale offer. Offers on the same property routinely vary by 10 percentage points or more.

What to do this week

1. Find out how long the property has officially been recorded as empty — ring the council's council tax department and ask for the date on file. Dispute it if it's wrong.
2. Ask which premium, if any, your council has determined, and at what rate.
3. Check whether Class G, I or M applies to you, and claim it in writing.
4. Notify your insurer or arrange an unoccupied policy. Today.
5. Decide honestly whether you're a renovator or a seller.
6. If you're selling, get at least three comparable valuations before you commit to a route.

If you disagree with a premium the council has applied, raise it with them first — they can amend it on the spot where the evidence supports you. If that goes nowhere, you can appeal to the Valuation Tribunal, and appeals are free.

The bottom line

An empty house is not a neutral asset sitting quietly in the background. It costs you every single month, in council tax you didn't budget for, insurance that may not respond, and a building that is deteriorating while you decide. The exceptions are real and worth claiming, but they're finite. Class G buys you twelve months, once.

Use that year properly. Work out what the house is genuinely worth, decide whether speed or price matters more to you, and get more than one offer before you commit to anything. If you'd like to see what a quick sale would realistically look like alongside the open-market figure, compare offers here — it's free, there's no obligation, and knowing both numbers is the only way to make this decision with your eyes open.
