High-Value Council Tax Surcharge Calculator (2028) Trending

The High Value Council Tax Surcharge (HVCTS) was announced in the November 2025 Budget and is due to start in April 2028. It is a new annual charge on the owner of a residential property in England with a current market value of £2 million or more, paid on top of normal Council Tax. It affects fewer than 1% of homes and is expected to raise around £430 million a year, so it is a narrow charge aimed at the top of the market rather than a general Council Tax rise.

The surcharge starts at £2,500 a year for properties worth £2m or more and rises to £7,500 a year for properties worth over £5m. There are four bands: a home valued between £2m and £2.5m pays £2,500, one between £2.5m and £3.5m pays £3,500, one between £3.5m and £5m pays £5,000, and anything above £5m pays £7,500, with all four charges rising with CPI each year from 2029/30. The government consulted from 19 May to 14 July 2026 on how the charge will work in practice (liability, deferral, exemptions and appeals) rather than on the bands themselves, and its response had not been published by late September 2026.

None of this replaces your existing Council Tax band, which is still worked out from 1991 values. The Valuation Office will value the properties concerned at 2026 levels before the charge starts, then revalue them every five years, the first revaluation falling in 2033. Because the surcharge falls on the owner rather than the occupier, a landlord letting a high-value property would pay it directly. Enter a property's current market value above and the calculator places it in its band and shows the annual figure.

Ordinary Council Tax varies enormously before any surcharge is added, and it helps to know what the bill is made of. Roughly 75% funds the main council, about 15% is the adult social care precept, around 6% goes to police, 3% to fire and 1% to parish councils where they exist. Councils have been able to add an extra 2% for adult social care each year since 2017, and in many areas that has accumulated to between 14% and 18% of the bill by 2026. Lower-spending authorities tend to be slightly cheaper, while areas with more deprivation need more services per resident, which drives much of the variation.

For 2026/27 the average Band D bill in England is £2,392, up 4.9%, and 70% of councils charge between £2,300 and £2,600. Dorset is the highest at £2,765 and Wandsworth the lowest at £1,028. The other bands are fixed fractions of Band D, from 6/9 at A through 7/9, 8/9, 11/9, 13/9 and 15/9 to 18/9 at H, so the England average runs from £1,595 at Band A to £4,784 at Band H. London is the outlier, averaging £2,068 at Band D including the Greater London Authority precept, which works out at about £1,379 at Band A and £4,136 at Band H. Northern Ireland has no bands at all, charging domestic rates on each home's capital value as at 1 January 2005.

Discounts come off before anything else. A single adult gets 25% off wherever they live, a household where everyone is a student is fully exempt, and a home adapted for a disabled resident is billed at the band below its own. Pension Credit recipients normally receive a full Council Tax Reduction, while working-age claimants go through their council's own scheme, which differs sharply from place to place and in some areas caps help at 80%. Empty homes usually get anything from nothing to a full discount for the first one to three months, after which a premium of up to 300% can apply, and in England a second home can be charged a premium of up to 100% (double the bill) since April 2025, while Welsh councils can go as high as 300%.

Challenging your band through the Valuation Office is worth considering if neighbours in similar houses sit lower, though only about 15% of challenges succeed and you can be moved up as easily as down. Geography is the bigger lever, since the £1,028 charged at Band D in Wandsworth against £2,765 in Dorset is a difference of £1,737 a year for the same band, with Westminster and the City of London also near the bottom. Claim the single person discount if you live alone, and check Council Tax Reduction if your income is low, because Pension Credit recipients under-claim it badly. Most councils bill over ten instalments from April to January but will spread the year over twelve if you ask. Formal payment holidays are rare, although some councils offer breathing space in cases of severe hardship.
