Second Home & Empty Property Premiums in 2026: The Full Picture
The numbers you see on a Council Tax bill marked "premium" are not a fine, a tax surcharge, or a one-off penalty — they are a permanent multiplier on your annual bill for as long as the property's status remains unchanged. For an owner of a £2,500/year Band D property in a council that has adopted the maximum 100% second home premium, that is an extra £2,500 every single year, indefinitely, with no cap on how many years it can run.
Since 1 April 2024, the rules changed substantially across Great Britain. England gained new powers under the Levelling-up and Regeneration Act 2023 to charge a 100% premium on furnished second homes, and the qualifying period for the long-term empty premium was cut from two years to one year. Wales went further, allowing councils discretion to charge up to 300% on either category from the start. Scotland introduced its own 100% ceiling for both second homes and long-term empty dwellings via separate regulations.
The headline figures hide an important detail: these are ceilings, not fixed national rates. Each billing authority decides separately whether to adopt a premium, at what percentage (up to the legal maximum), and from which date. Two neighbouring streets in different council areas — or even different parishes within the same county — can face entirely different bills for an identical property.
| Nation | Second home premium | Empty 1–5 yrs | Empty 5–10 yrs | Empty 10+ yrs |
|---|---|---|---|---|
| EN England | Up to 100% | Up to 100% | Up to 200% | Up to 300% |
| WA Wales | Up to 300% | Up to 300% | Up to 300% | Up to 300% |
| SC Scotland | Up to 100% | Up to 100% | Up to 100% | Up to 100% |
Premiums interact with property value, location and how long a property has sat empty in very different ways. The three scenarios below use real-world bill sizes to show how the same starting point can lead to dramatically different outcomes.
Scenario 1 — Coastal cottage used as a holiday home (England)
A Band D coastal cottage in a Cornish council area with a standard bill of £2,310, used only a handful of weekends a year and registered as a second home where the council has adopted the full 100% premium.
| Item | Amount |
|---|---|
| Standard annual bill (100%) | £2,310.00 |
| Second home premium (100%) | +£2,310.00 |
| Total annual bill | £4,620.00 |
| Effective monthly cost | £385.00 |
Scenario 2 — Inherited terraced house, empty for 7 years (England)
A modest terraced house with a standard bill of £1,750, inherited and left empty and unfurnished while ownership was disputed between family members. It now falls into the 5–10 year empty bracket, attracting a 200% premium.
| Item | Amount |
|---|---|
| Standard annual bill (100%) | £1,750.00 |
| Long-term empty premium (200%) | +£3,500.00 |
| Total annual bill | £5,250.00 |
| Effective monthly cost | £437.50 |
Note that this is three times the standard bill for a property generating zero income — a powerful illustration of why probate delays can become extremely costly the longer they drag on. See the section below on edge cases for how the probate exemption interacts with this timeline.
Scenario 3 — Welsh holiday let, council applies the maximum (Wales)
A renovated cottage in a Welsh county that has adopted the 300% ceiling for second homes, with a standard bill of £1,980.
| Item | Amount |
|---|---|
| Standard annual bill (100%) | £1,980.00 |
| Second home premium (300%) | +£5,940.00 |
| Total annual bill | £7,920.00 |
| Effective monthly cost | £660.00 |
At a 300% premium, the Council Tax bill alone is roughly equivalent to a small mortgage payment — a major factor pushing some Welsh second-home owners to either register the property as a furnished holiday let that meets occupancy thresholds for business rates, or to sell entirely. The next section looks at exactly that decision.
Once a premium is applied, the property's "do nothing" cost rises sharply, which changes the economics of every alternative. The comparison below uses Scenario 1 above (£2,310 standard bill, England, 100% second home premium) to illustrate how the numbers shift depending on what you do with the property.
| Option | Annual Council Tax cost | Key trade-off |
|---|---|---|
| A Keep as second home | £4,620 (premium applies) | Full personal use, but the highest ongoing cost with no income offset |
| B Long-term let (12-month tenancy) | £0 (tenant pays Council Tax) | Premium no longer applies once it is someone's sole residence, but you lose personal access and gain landlord obligations |
| C List for sale and leave empty | £2,310 for up to 12 months, then £4,620+ | Marketing exemption buys time, but the premium resumes in full if unsold after the exemption period |
| D Convert to qualifying furnished holiday let | £0 Council Tax, but business rates apply | Requires meeting letting-day thresholds set by the Valuation Office Agency; small business rates relief can reduce the rates bill to nil for many properties |
Option D often looks attractive on paper, but it is not a simple form-filling exercise. To be assessed for business rates rather than Council Tax in England, a property generally needs to be available for short-term letting for at least 140 days a year and actually let for a minimum number of days — and the rules have tightened in recent years specifically to stop owners using it purely to dodge the second home premium. If you are considering this route, model both the occupancy commitment and the loss of personal flexibility honestly before committing.
Because the empty-home premium escalates at fixed time thresholds rather than gradually, the cost of inaction does not rise smoothly — it jumps sharply at the 1, 5 and 10-year marks. The table below tracks the cumulative extra Council Tax paid (premium only, on top of the standard bill) for a £2,000/year property in England that remains empty throughout.
| Time empty | Premium rate | Extra cost that year | Cumulative extra cost |
|---|---|---|---|
| Year 1 | 0% (under threshold) | £0 | £0 |
| Years 2–5 | 100% | £2,000 / yr | £8,000 |
| Years 6–10 | 200% | £4,000 / yr | £28,000 |
| Year 11 onward | 300% | £6,000 / yr | £34,000+ and rising |
By year ten, the owner has paid an additional £28,000 purely in premiums — money that delivers no improvement to the property and is entirely separate from lost rental income, ongoing insurance costs for unoccupied buildings (which are typically higher), and maintenance issues that worsen the longer a property sits empty. Viewed this way, even a modest renovation budget that brings a derelict property back into use within the first year is almost always the cheaper path over a 10-year horizon, even before accounting for the value the renovation itself adds to the property.
Premiums cannot legally be applied in certain circumstances, but — unlike the premium itself — exemptions are rarely applied automatically. You must notify your council and, in most cases, provide evidence.
Two changes dominate the 2025–2026 transition for owners of second homes and empty properties:
| Change | Before | From 2025/26 onward |
|---|---|---|
| Empty home premium threshold | 2 years | 1 year |
| Second home premium (England) | Not generally permitted | Up to 100%, subject to 12 months' advance notice |
| Council adoption (England & Wales) | Handful of high-demand areas | Majority of coastal, rural and high-tourism authorities |
Council Tax itself sits outside the income tax system, but the premium can interact with other tax decisions in ways that are easy to overlook.
For owners weighing up the furnished holiday let route discussed earlier, it is worth knowing that the previous favourable tax treatment for furnished holiday lettings (such as more generous mortgage interest relief and capital allowances) has been phased out, with such properties now taxed in line with standard residential lets for income tax purposes. This does not change the Council Tax versus business rates classification directly, but it does mean the income tax benefit that used to accompany an "FHL" property is smaller than it once was — so the decision should be based primarily on the Council Tax and occupancy implications, not on a tax advantage that no longer exists in the same form.
Premium payments are not a deductible expense against rental income for properties that remain empty and unlet, since there is no rental activity to set them against. They are simply a personal cost of ownership.
- Assuming a discount carries over. A property that previously qualified for an empty-property discount or exemption under old rules does not automatically retain that status — premiums are assessed against current rules and current circumstances.
- Not informing the council of a sale attempt. The marketing exemption is not inferred from a "For Sale" board — councils typically require you to register the claim and supply evidence such as the agency agreement.
- Believing furnishing status doesn't matter. Whether a property is "furnished" or "unfurnished" is the dividing line between the second home premium and the empty home premium in most areas, and councils can and do send inspectors to verify this.
- Letting the marketing exemption lapse unnoticed. The 12-month clock starts from a fixed date — if the property remains unsold after that point, the premium resumes automatically and is rarely backdated for a renewed exemption.
- Forgetting that ownership changes restart the clock differently in different councils. In some areas, a change of ownership resets the empty-home duration count; in others, the council looks at the physical state of the property regardless of who owns it. Confirm your council's specific position.
- Underestimating insurance and maintenance alongside the premium. Unoccupied property insurance is typically more expensive and has stricter conditions (such as regular inspection visits) — a cost that is easy to forget when budgeting only for the Council Tax premium itself.
