The Statutory Formula: 1991 Valuation Bands and the Band D Baseline
Under Section 5 of the Local Government Finance Act 1992, every domestic property in England and Scotland is assigned to one of eight valuation bands (Bands A through H) based on its estimated open-market capital value as of 1 April 1991.
Local councils do not calculate individual bills from scratch for every address. Instead, the local billing authority sets an annual headline charge for a benchmark 'Band D' property. All other bands are statutory fractions of this Band D baseline, fixed by Parliament in ninths (6/9th for Band A up to 18/9th for Band H).
Regardless of how much local property prices fluctuate from year to year, the ratio between bands remains permanently fixed by statutory law.
| Valuation Band | 1 April 1991 Capital Value (England) | Statutory Ratio to Band D | Multiplier Factor | Typical Proportion of Total Bill |
|---|---|---|---|---|
| Band A | Up to £40,000 | 6/9 | 0.667 (66.7%) | Lowest standard residential charge |
| Band B | £40,001 to £52,000 | 7/9 | 0.778 (77.8%) | Common for terraced homes and flats |
| Band C | £52,001 to £68,000 | 8/9 | 0.889 (88.9%) | Most common UK semi-detached homes |
| Band D | £68,001 to £88,000 | 9/9 | 1.000 (100.0%) | National benchmark reference rate |
| Band E | £88,001 to £120,000 | 11/9 | 1.222 (122.2%) | Substantial semi-detached & smaller detached |
| Band F | £120,001 to £160,000 | 13/9 | 1.444 (144.4%) | Medium to large 4-bedroom detached |
| Band G | £160,001 to £320,000 | 15/9 | 1.667 (166.7%) | Substantial executive family homes |
| Band H | Over £320,000 | 18/9 | 2.000 (200.0%) | Top statutory bracket (exactly 2x Band D) |
The Precept Anatomy: Where Your Council Tax Money Goes
Your annual Council Tax demand notice is not a single tax for a single entity. It represents a consolidated collection notice combining levies (called 'precepts') issued by multiple independent statutory bodies operating across your administrative boundaries.
In two-tier local government areas (such as non-metropolitan shire counties), the billing authority (your district or borough council) collects money on behalf of the upper-tier county council, police commissioner, and fire service. In single-tier unitary authorities, metropolitan boroughs, and London boroughs, a single council provides most services directly.
Since 2016, central government regulations allow county councils and unitary authorities to levy an additional, ring-fenced percentage on top of general Council Tax exclusively to fund adult social care for elderly and vulnerable residents. This charge appears as a separate cumulative line item on your bill.

Statutory Reductions and Premium Levies
Certain households and circumstances alter the baseline calculation significantly under statutory legislation:
Under Section 11 of the 1992 Act, properties occupied by only one qualifying adult receive an automatic 25% discount. If all adult residents qualify as students or individuals with severe mental impairments (SMI), a 100% exemption applies under Council Tax (Exempt Dwellings) Order 1992.
Conversely, under the Levelling-up and Regeneration Act 2023, councils possess statutory powers to levy empty home premiums of up to 100% for homes empty over one year, 200% for homes empty over five years, and up to 300% for homes left unoccupied for ten years or more.
