Glossary
Council tax, in plain English.
Every acronym and legal term you’ll hit while checking your band or building an appeal — defined without the jargon.
Valuation Office Agency (VOA)
The government agency that sets and reviews council tax bands for every home in England and Wales.
Band D
The reference council tax band. Every other band is expressed as a fixed ratio of Band D.
Band ratios
The fixed multipliers used to calculate each band's bill from the Band D charge.
1991 valuation
The date every English council tax band is set from — 1 April 1991. Never updated since.
Proposal
The formal name for a council tax band challenge submitted to the VOA.
Valuation Tribunal
The independent body that hears council tax band appeals when a proposal to the VOA fails.
Listing officer
The VOA official responsible for the valuation list in a particular billing area.
Billing authority
The council that issues your council tax bill and collects the money — usually your district or unitary council.
Disabled band reduction
A discount that drops your council tax bill by one band if a disabled person lives at the property with specific adaptations.
Single person discount
A 25% discount on your council tax bill if you're the only adult in the household.
Council Tax Reduction (CTR)
A means-tested reduction for low-income households, run by each council. Different from a band appeal.
Comparable properties
Similar homes near you, ideally on the same street, used as evidence in a band challenge.
The neighbours test
The quickest check: if identical homes on your street are in a lower band than yours, your band is likely wrong.
Aggregate valuation
The 1991 approach of valuing many homes at once from limited data — the reason so many bands are wrong.
Council tax base
The total number of Band D equivalent properties in a council area — used to set the Band D charge.
Banding review
An informal request to the VOA to look at your band again — the step before a formal proposal.
Effective date
The date a band change takes effect — usually the date you moved in, not the date the VOA agrees.
Backdated refund
Council tax refunded for the years you overpaid before a successful band challenge.
Chargeable dwelling
A property that attracts council tax — most homes, but not all buildings on a plot.
HMO banding
Whether a house in multiple occupation is banded as one property or one band per room.
Exempt property
A home that pays no council tax at all — e.g. all-student households, care-home residents.
Empty property premium
The extra charge — up to 300% — councils can add to homes left empty for a long time.
Material increase
A building improvement (extension, loft conversion) that can trigger a re-band when the property is sold.
Material reduction
A change that reduces a home's value — demolition, subsidence — and can lower the band immediately.
Revaluation
A complete re-banding of every home. England has never had one; Wales did in 2003.
Tone of the list
The general level of bands across a street or area — the VOA's benchmark for consistency.
Drive-by valuation
The 1991 approach where valuers assigned bands from the street without going inside — a major source of errors.
Valuation list
The official record of every home's council tax band, maintained by the VOA.
Second home premium
The extra council tax councils can charge on furnished homes that aren't a main residence — up to 100% from April 2025.
Statutory appeal window
The narrow six-month window to formally challenge a band after moving in or after certain triggering events.
New-build banding
The VOA process for banding a newly-built home — retrofitted to a notional 1991 value.
