From April 2028, owners of residential property in England worth £2 million or more will pay a new annual charge on top of their existing council tax. This article sets out how the High Value Council Tax Surcharge is designed, who would be liable, and what the government’s consultation proposed on valuation, deferral and appeals.
What is the High Value Council Tax Surcharge?
The surcharge was announced by the government on 28 November 2025. According to government guidance, it is a recurring annual charge on owners of residential property in England valued at £2 million or more, and it is separate from, and additional to, ordinary council tax. Existing council tax bands, which still rest on 1991 values, are unaffected, and changes to them would not alter whether a home falls within the new charge.
Three features set it apart from council tax:
- It falls on owners, not occupiers. A tenant in a £3 million house would not receive the bill; their landlord would.
- It is England only.
- It is banded by current value. The Valuation Office, part of HM Revenue and Customs, will run a separate, targeted valuation exercise to determine what a property was worth in 2026.
The government says fewer than 1% of residential properties in England are expected to be affected, and estimates the charge will raise around £430 million a year from 2028/29.
How much will each band cost?
There are four bands, according to the government’s published design.
| Property value (2026) | Annual surcharge |
|---|---|
| £2.0m to £2.5m | £2,500 |
| £2.5m to £3.5m | £3,500 |
| £3.5m to £5.0m | £5,000 |
| £5.0m and above | £7,500 |
Charges are due to rise each year in line with consumer price inflation from 2029-30. The charge is a flat sum within each band, not a percentage of value, so it behaves very differently from a conventional property tax.
What does it look like as a share of value?
Illustrative arithmetic shows how regressive or progressive the design feels at different points. These are worked examples, not forecasts.
- A home valued at exactly £2m pays £2,500, which is 0.125% of its value (2,500 ÷ 2,000,000).
- A home valued just under £2.5m pays £2,500, close to 0.10% of its value (2,500 ÷ 2,500,000); once it tips into the next band the charge becomes £3,500.
- A £5m home pays £7,500, or 0.15%.
- A £10m home also pays £7,500, which is 0.075%.
The pattern is clear: because the top band has no ceiling, the heaviest relative burden falls on homes at the bottom of each band, and the lightest on the most expensive properties. That is analysis rather than reporting, and it is a design choice the government has defended on grounds of simplicity. According to the consultation document, it chose bands for “simplicity for taxpayers and stability in the tax base”.
Why do the thresholds matter so much?
Any banded charge creates cliff edges. Using the published bands, a home valued at £1.99m pays nothing, while one valued at £2.0m pays £2,500. A home just below £2.5m pays £2,500, and one just above it pays £3,500, a £1,000 jump for a small difference in value.
This makes the valuation itself the central issue. The consultation sets out an approach that uses comparable sales, adjusted for differences between properties, supported by automated valuation models with professional valuers reviewing the results. The data sources listed include the Valuation Office’s own database, Stamp Duty Land Tax records, local authority planning data and geospatial data. Owners near a threshold are the group most likely to care about how accurate that process proves to be.
How will the process run, and when?
According to the consultation, the timetable runs as follows:
- The Valuation Office publishes a draft list of properties in scope in late 2027.
- Local authorities identify owners and send the first bills in March 2028.
- Collection follows the standard council tax cycle, with twelve monthly instalments as the default and a ten-payment option available.
- Revaluations take place every five years, with the next in 2033.
After April 2028, band changes would typically occur only on a sale, merger, split or revaluation, rather than because an owner has carried out improvements alone. New-build homes are proposed to be exempt until first sale or twelve months after completion.
Who counts as the owner?
The consultation proposed that liability should follow legal ownership. For long leaseholders, that means anyone whose lease was initially granted for more than 21 years, or is treated in law as having been. Joint owners would be jointly and severally liable. Where a company holds legal title, the company is liable, and trustees would be liable under trust arrangements, including bare trusts where beneficiaries cannot easily be identified.
The same document reports that over 90% of properties worth £2 million or more in 2024 were owner-occupied, so the charge will largely reach people living in the homes they own rather than landlords or investors.
What happens if an owner cannot pay?
The proposals include a deferral scheme for eligible owners of a main residence, allowing payment to be postponed until the property is sold or ownership otherwise changes. As proposed:
- Eligibility would turn on household income of £35,000 or less, or capital savings of £16,000 or less.
- Certain disability criteria, including severe mental impairment certified by a medical professional, would also qualify.
- Second homes and corporate owners would be excluded.
- Interest would be charged during deferral, with a secured charge placed on the property. The consultation set out options for the rate, including 3.75% (the HMRC official rate or the Bank of England base rate, as the document states them) and 4.75% (the adult social care deferred payment rate).
For asset-rich, income-poor owners, such as older residents of long-held London homes, this mechanism will matter more than the headline bands.
Can owners challenge a band or a bill?
Yes, and the consultation gave this considerable space. Owners could challenge a banding, their liability, the calculation of a bill, or whether a property should be in scope at all. Proposed windows were eight months to challenge an initial banding, then six months thereafter, with no time limit on challenges about liability or exemptions because circumstances change. The Valuation Office would have four months to respond to banding challenges, and local authorities two months on liability. Appeals would go to the Valuation Tribunal for England.
Enforcement would mirror council tax: reminders, a demand for the full annual balance, liability orders from magistrates’ courts, attachment of earnings and enforcement agents. Penalties of 10% of annual liability would apply after 21 days of failing to respond to an information request, rising to 30% after a further 21 days.
Which properties are exempt or eligible for discounts?
Proposed exemptions include properties not valued by the Valuation Office, such as purpose-built student halls, Ministry of Defence accommodation, diplomatic property, registered social housing, care homes and hospices, and domestic violence refuges. Charitable properties and tied properties linked to employment, particularly agricultural, were proposed as discounts and remain under consultation.
Where does this leave London buyers and owners?
The government says it will bring the main provisions forward in a future Finance Bill, and has not yet published its response to the consultation, which ran from 19 May to 14 July 2026. Details may therefore change.
The geography matters for this publication’s readers, since prime London is where high-value stock is most likely to sit, and the surcharge adds a recurring cost to the ownership costs of such homes. It is relevant to the shifts in prime values explored in why prime London property is changing beyond the traditional postcodes, and it sharpens the arithmetic discussed in why more wealthy buyers are renting instead of owning. Readers following the wider fiscal picture may also want what the Autumn Budget could mean for pensions and ISAs.

A modest charge with a large valuation question
Set against a £2 million home, £2,500 a year is a small sum, and the government’s own revenue estimate of around £430 million is modest in the context of public finances. The more consequential questions are administrative: how accurately a 2026 valuation can be reached without a visit, how fairly it treats homes close to a threshold, and how well deferral works for owners with little income. Those answers will emerge from the government’s response and the Finance Bill, not from the bands themselves.
