How Council Tax Bands Are Set by the VOA: Data, Anomalies and How to Appeal

Council tax bands in England were set in 1991 and have never been revalued. This guide explains how the Valuation Office Agency assigns bands, why anomalies are common, and how to challenge a band you believe is wrong.

The 1991 Valuation — Still Governing England's Council Tax

Council tax was introduced in England on 1 April 1993, replacing the short-lived Community Charge (poll tax). At that point, the Valuation Office Agency (VOA), an executive agency of HMRC, valued every residential property in England against an estimated open market value as at 1 April 1991 — a date chosen as a neutral reference point before the scheme launched.

Properties were then assigned to one of eight bands (A through H) based on that estimated 1991 value:

Band	1991 Value Range
A	Up to £40,000
B	£40,001–£52,000
C	£52,001–£68,000
D	£68,001–£88,000
E	£88,001–£120,000
F	£120,001–£160,000
G	£160,001–£320,000
H	Over £320,000

England has not conducted a revaluation since 1991. Wales revalued in 2003 and introduced a band I for properties over £424,000. Scotland operates a similar band system based on 1991 values. Northern Ireland uses a different system based on current capital value.

The result of three decades without revaluation is that the relationship between council tax bands and actual property values is profoundly distorted. A terraced house in a northern city may sit in band B and pay £1,400 per year; a similar house in London may be in band D and pay £2,500 — not because it uses more council services, but because its 1991 value happened to fall across a band boundary.

How the VOA Assigns Bands to New Properties

When a new property is built or created (through subdivision, conversion, or new construction), the VOA must assign it a council tax band. Since there is no 1991 comparator for a property that did not exist in 1991, the VOA uses a "1991 antecedent valuation" approach: it estimates what the property would have been worth on 1 April 1991, using comparable evidence from properties that were valued at the time.

This is an inherently imprecise exercise. VOA caseworkers use available evidence — nearby properties of similar type, size and construction — to make a judgement call. For properties in areas with a homogeneous housing stock, this is straightforward. For unusual properties, conversions, or developments in areas where 1991 comparables are thin, the antecedent valuation is essentially an estimate.

Common Causes of Band Anomalies

Several factors cause properties to be incorrectly banded relative to their neighbours:

**Conversion errors:** When a large house is converted into flats, each flat should be separately banded at a value reflecting its individual size and characteristics. In practice, some conversions result in flat values that do not adequately reflect their size relative to similar flats in the area.

**Band A clustering:** In areas where 1991 values were compressed at the lower end of the scale, many properties of quite different sizes and qualities may share band A simply because they all fell below £40,000 in 1991.

**Material changes at build:** If a developer made changes to a property during construction after the antecedent valuation was made, the banding may not reflect the final specification.

**Clerical errors:** The original 1991 valuation exercise was conducted at enormous scale in a short period. Errors in property type, description and comparators do occur and have been found decades later on challenge.

How to Appeal Your Council Tax Band

You can challenge your council tax band at any time, but the grounds for challenge are restricted. You cannot challenge simply because you think it is too high. You can challenge if:

You are a new resident in the property and believe the band is wrong (challenge must be made within six months of becoming liable).
There has been a material increase or decrease in the property's value since the band was set (for example, demolition of part of the property, or the removal of a feature that was previously reducing its value).
The property has been split into multiple dwellings, or dwellings have been merged.
A property has been incorrectly banded from the outset — this ground is available at any time.

The challenge process, under the Council Tax (Alteration of Lists and Appeals) (England) Regulations 2009, works as follows:

1. **Propose an alteration** to the VOA by submitting your challenge via the VOA's online portal at gov.uk. Include your evidence — comparable properties in the same street or area with lower or higher bands, details of the property's characteristics.

2. The VOA will consider the proposal and may contact you for further information.

3. If the VOA agrees, the band will be altered. If it disagrees and you remain dissatisfied, you can **appeal to the Valuation Tribunal for England (VTE)**, an independent tribunal.

4. The VTE will hear evidence from both sides and make a determination. If it finds in your favour, the band will be reduced (and you may receive a backdated refund).

A word of caution: appeals can result in a band increase as well as a reduction if the evidence suggests the property was undervalued. This "upward appeal" risk is real — the VOA can also raise a band at any time it believes there has been an error. Before appealing, check comparable properties on the VOA's Council Tax band finder at gov.uk to understand whether your band is genuinely anomalous.
