Council Tax Premium on Second Homes UK 2026: What You Need to Know

Owning a second home in the UK has become noticeably more expensive. Since April 2025, councils in England have had the power to charge a 100% council tax premium on second homes and on properties that have been empty for more than one year. In Wales, premiums have been in place longer and can reach 300%. If you own a holiday cottage, investment property or pied-a-terre that is not your main residence, this guide explains what you could be paying and what options you have.

What Is the Council Tax Premium?

The standard council tax bill reflects your property's band and the local authority's annual rate. A premium is an additional percentage charged on top of that standard bill. For second homes, the premium effectively doubles your council tax at the maximum rate.

For example, if a property would normally attract an annual council tax bill of GBP 2,200, a 100% premium means a total bill of GBP 4,400. The additional amount goes entirely to the local authority -- it is not set by central government, and each council decides independently whether and how much to charge within the statutory limits.

Second Homes vs Long-Term Empty Properties

Councils distinguish between two categories:

Second homes are properties where no one lives as their sole or main residence, but which are substantially furnished. Holiday cottages, weekend retreats and investment flats held vacant are all potential second homes for council tax purposes.

Long-term empty properties are those that have been unoccupied for more than one year. The premium for these starts at 100% after one year and can increase to 200% after five years and 300% after 10 years in England.

In both cases, councils can choose to apply a premium at any level up to the statutory maximum, or not apply one at all. This creates significant variation across England.

Which Councils Apply the Premium?

Not every council uses the premium power. As of 2026, uptake is particularly high in:

• Rural and coastal areas with high concentrations of holiday lets, where second homes are seen as contributing to housing affordability problems.
• Wales, where the Welsh government has moved more aggressively, enabling premiums of up to 300% on both empty properties and second homes.
• Some urban councils where high proportions of empty investment properties have drawn political attention.

To find out whether your council applies a premium and at what rate, check your council's website or contact the revenues department directly. Councils must publish their premium policy.

Exemptions and Discounts

Even where a premium applies, some properties are exempt. Common exemptions include:

• Properties that are the main residence of at least one person who is working away from home (armed forces personnel, for example).
• Annexes occupied by a dependent relative.
• Properties that cannot be occupied year-round due to planning restrictions (relevant for some holiday properties with seasonal occupation conditions).
• Properties undergoing major structural repair or refurbishment (typically limited to 12 months).
• Properties marketed for sale or let and genuinely on the market (though councils scrutinise this closely).
• Probate properties where someone has recently died (usually six months after probate is granted).

The rules vary slightly by council, and exemptions are not automatic -- you must apply.

Furnished Holiday Let Status and Planning

One strategy some owners have used is to register their property as a furnished holiday let (FHL) for tax purposes, which in some areas can reclassify it for business rates rather than council tax. If a property pays business rates instead of council tax, the council tax premium does not apply.

However, HMRC abolished the specific furnished holiday let tax regime for income tax and CGT purposes from April 2025. The business rates classification is a separate question governed by the Valuation Office Agency, not HMRC, and depends on genuinely offering the property for short-term letting for at least 140 days per year and actually letting it for at least 70 days. These are minimum thresholds and councils can investigate whether lettings are genuine.

Moving a property to business rates is not a simple administrative step -- it requires meeting the letting criteria and being assessed by the Valuation Office Agency. Councils and the VOA are increasingly alert to properties switching classification primarily to avoid the council tax premium.

Challenging the Premium

If you believe a premium has been applied incorrectly, you can appeal. Grounds for appeal include:

• The property qualifies for an exemption that has not been applied.
• The council has incorrectly classified the property as a second home when it is, in fact, your main residence.
• A discount should apply for another reason (such as the property being undergoing renovation).

Appeals go initially to the billing authority (the council). If unresolved, you can take the matter to the Valuation Tribunal for England (or the equivalent body in Wales). Gathering evidence -- letting records, utility bills, correspondence -- before making an appeal strengthens your position.

Planning Considerations for Owners

If you own a second property and the premium is significantly increasing your costs, consider:

• Letting the property. A property genuinely let to tenants on a residential tenancy is the tenant's main residence, which changes its council tax status.
• Selling. The stamp duty land tax (SDLT) surcharge on second homes (an additional 5% above the standard rates from October 2024) combined with the council tax premium and the loss of the furnished holiday let regime has made the economics of holding holiday properties tighter.
• Main residence review. If the property is actually where you spend most of your time, ensure the council tax records reflect the correct main residence designation. Only one property can be your main residence for council tax purposes at any one time.
