How It Works
Council Tax bands in England are based on property valuations from 1 April 1991. Band H currently covers all properties valued above £320,000 at that date, meaning a modest terraced house in central London and a country estate may both sit in the same band. Proposed reforms would introduce bands I, J, and K above the existing Band H to create a more proportional system for the highest-value properties.
Under the consultation framework published for potential implementation from 2028, properties in proposed Band I would pay approximately 1.25 times the Band D rate, Band J around 1.5 times, and Band K approximately 1.75 times. Current Band H already charges twice the Band D rate. The exact multipliers and valuation thresholds are subject to parliamentary approval and may vary by billing authority.
To estimate your potential liability, the calculator applies these proposed ratios to your local authority's current Band D charge. For example, if Band D is £2,100 and your property falls into proposed Band J, your annual bill would be roughly £2,100 x 1.5 = £3,150. Revaluation itself would redistribute all properties across all bands, so many homes currently in lower bands could also see changes.
Estimated council tax for a high-value London property
- Property estimated 1991 value: £550,000 (current market value ~£3.2 million)
- Local authority Band D rate: £1,950 per year
- Current Band H charge: £1,950 x 2.0 = £3,900
- Proposed Band K multiplier: 1.75 x Band D = £1,950 x 1.75 = £3,412.50
- Potential increase if revaluation places property in Band K: difference depends on final legislation and local precepts
