1. About this release

This release contains statistics relating to the stock of properties on the England and Wales Council Tax Valuation Lists. The statistics provide information on the number and type of domestic properties (known as “dwellings”), as well as the insertions to and deletions from the Council Tax Valuation Lists. It is the latest in the series of annual publications from the Valuation Office Agency (VOA). This publication includes statistics by financial year from 1 April 1993 to 31 March 2024.

This update includes the following tables:

2. Background notes

The VOA is an Executive Agency of HM Revenue and Customs. One of the responsibilities of the VOA is to provide Council Tax bands for properties in England and Wales. It does not set the level of Council Tax nor collect the tax; these are tasks for local government. Council Tax is a local tax set by local authority districts to help pay for local services. It uses the relative value of properties to determine each household’s contribution to these local services.

The VOA has had responsibility for banding properties for Council Tax since the tax was first introduced in 1993. Before 1993, the VOA was responsible for valuation of properties under the earlier system of domestic rates.

It is the duty of the VOA to make sure that each property is correctly assessed and placed in the right band. This ensures that there is a consistent and objective basis on which local authority districts can determine the amount they charge each household in Council Tax. The VOA maintains a high level of professionalism when carrying out this duty.

The VOA places each property into a valuation band; there are eight bands for properties in England and nine bands for properties in Wales. The valuation band is assigned to a property on the basis of its value at 1 April 1991 for England (for the 1993 Council Tax Valuation List) and 1 April 2003 for Wales (for the 2005 Council Tax Valuation List); this band then determines the amount of Council Tax to be paid. New properties are assigned a band based on what their value would have been on either 1 April 1991 (properties in England) or 1 April 2003 (properties in Wales). The basis of valuation is set down in regulations made under the Local Government Finance Act 1992. Minor updates were made to the initial regulations in 1994 but they have not been changed since.

The following tables show the breakdown of bands for England and Wales:

England

Band	Value of property (at 1 April 1991)
A	Up to £40,000
B	£40,001 up to £52,000
C	£52,001 up to £68,000
D	£68,001 up to £88,000
E	£88,001 up to £120,000
F	£120,001 up to £160,000
G	£160,001 up to £320,000
H	£320,001 and above

Wales

Band	Value of property (at 1 April 2003)
A	Up to £44,000
B	£44,001 up to £65,000
C	£65,001 up to £91,000
D	£91,001 up to £123,000
E	£123,001 up to £162,000
F	£162,001 up to £223,000
G	£223,001 up to £324,000
H	£324,001 up to £424,000
I	£424,001 and above

3. Data information and methodology

3.1 Updates to previously published statistics since 31 March 2023

Figures this year represent an increase of 225,410 (0.8%) properties with a Council Tax band in the year since 31 March 2023. This increase is higher in England (0.9%) than in Wales (0.5%). The following table shows the net change in properties with a Council Tax band between 31 March 2023 and 31 March 2024, by band and country.

Band	England and Wales	England	Wales
A	31,180	30,340	840
B	39,730	38,910	820
C	55,910	54,170	1,740
D	41,510	40,140	1,370
E	29,790	28,360	1,430
F	16,230	15,310	920
G	9,130	8,800	330
H	1,910	1,840	70
I	20	..	20
Total	225,410	217,870	7,540

Table notes: Counts are rounded to the nearest 10. ‘..’ denotes not applicable - bands in England range from A to H only.

3.2 Updates to previously published statistics

This publication includes annual statistics from 1993 to 2024. Statistics published in this release have been calculated using domestic property data extracted from the VOA’s administrative database as at 31 March 2024. Property attributes in the VOA database are always the most recent information for each property. Therefore, the number of properties by property type and build period for statistics from 1993 to 2023 may not be the same as those published in the 2023 release.

For example, the differences between the 2023 and 2024 releases, in terms of the number of properties on the council tax list as at 31 March 2023 by property type, are:

Property type	Data extracted at 31 March 2023	Data extracted at 31 March 2024	Difference
Bungalow	2,475,450	2,475,240	-220
Flat/Maisonette	6,307,620	6,306,870	-750
House Terraced	6,985,140	6,986,800	1,670
House Semi-Detached	6,364,470	6,362,420	-2,050
House Detached	4,326,650	4,327,190	540
Annexe	52,000	52,510	510
Caravan/Houseboat/Mobile Home	123,540	123,540	-
Unknown	189,250	189,550	300
Total	26,824,120	26,824,120	0

Table note: Figures are rounded to the nearest 10. Totals may not sum due to rounding.

Increases in the number of properties in a build period may happen for the following reasons:

• A non-domestic property, such as a pub or a barn, may have been renovated into a house; if the reconstruction work was not extensive, then the original build date of the property is used for the build period of the new house.
• A house may have been converted into flats; where the style of the property has not changed, the build period of the old house will be used for the new flats.
• Updated information on properties previously recorded as having an unknown build period.

Decreases in the number of properties in a build period may happen for the following reasons:

• If a property is completely rebuilt, or is converted in such a way that the style of the property has changed, the old property will be deleted from the list and a new property will be added; the build period will be derived from the date at which the work on the new property was completed.
• A property will be deleted from the lists if it has been demolished.
• If works are being carried out on the property, it may be temporarily removed from the lists due to being in a state of disrepair.
• A property may have been converted into a business, such as a shop or a holiday home; in this case, it will be transferred to the non-domestic rating list.

The differences between the 2023 and 2024 releases, in terms of the number of properties on the council tax list as at 31 March 2023 by build period, are:

Build period	Data extracted at 31 March 2023	Data extracted at 31 March 2024	Difference
Pre-1900	4,179,440	4,179,750	300
1900-1918	1,415,740	1,415,650	-100
1919-1929	1,297,040	1,297,090	50

1945-1954	1,739,210	1,739,150	-50
1955-1964	2,657,620	2,657,710	90
1965-1972	2,544,050	2,544,130	70

Unknown	229,400	229,490	90
Total	26,824,120	NA [see note]	NA [see note]

Table notes: Figures are rounded to the nearest 10. Totals may not sum due to rounding. Figures between 1 and 4 are denoted as ‘-’. In the 2023 publication the build period for 2022 to 2023 included properties built between 01 January 2022 and 31 March 2023. The latest build period in the 2024 publication covers properties from 01 January 2022 to 31 March 2024. Therefore, this build period and the overall total cannot be compared.

3.3 Assigning geographies

The statistical geographies used in this release have been assigned using two methodologies:

Method 1: Linking VOA BA Codes to Office for National Statistics (ONS) statistical geographies

Each property with a Council Tax band held on the VOA’s database is assigned to a Billing Authority, each of which have a unique Billing Authority code (BA code). These BA codes have been linked to the codes and names used in the UK statistical geographies maintained by the ONS.

Method 2: Linking VOA postcodes to ONS National Statistics Postcode Look-up File (NSPL)

Each property’s individual postcodes held on the VOA’s database have been linked to those appearing in the February 2024 version of the NSPL. On average, around 0.03% of the records in each financial year could not be matched with the NSPL. Counts for these records appear in the area ‘Unmatched’ row and may introduce a marginal geographical bias to the data.

Method 3: Linking VOA postcodes to ONS Postcode to Parliamentary Constituency (Post General Election) Lookup

Each property’s individual postcodes held on the VOA’s database have been linked to those appearing in the May 2024 version of the postcode to Parliamentary Constituency (post General Election) lookup produced by ONS. Note that this lookup is provisional at the time of production. This method has only been used to produce data on the basis of parliamentary constituencies after the July 2024 General Election; in the next publication, it is anticipated that these will be included in the NSPL (method 2).

Tables where different methods of geography assignment have been used should not be compared. The following table details which method was used in each table of this release:

Table	Geography assignment method
CTSOP1.0	Method 1 - BA codes
CTSOP1.1	Method 2 - Postcodes
CTSOP2.0	Method 2 - Postcodes
CTSOP2.1	Method 3 - Postcodes to Parliamentary Constituency (post General Election) lookup
CTSOP3.0	Method 1 - BA codes
CTSOP3.1	Method 2 - Postcodes
CTSOP4.0	Method 1 - BA codes
CTSOP4.1	Method 2 - Postcodes
CTSOP5.0	Method 1 - BA codes
CTSOP6.0	Method 1 - BA codes

For further information on the area codes used in this release, please refer to the please refer to the ONS Administrative Geography Guidance.

3.4 Assigning Property Type and Build period

Each entry on the Council Tax Valuation lists has a number of ‘Property Attribute Details’ (PADs) recorded, which are codes that describe the features of the property. One of these PADs is the property type code; for this release, this code has been grouped to give a simplified property type category. If a property has no property type code recorded, or if the property type is recorded as ‘House - Unknown’, it is counted as having an unknown property type. The look-up table in appendix 1 shows how the property type code has been grouped into the categories shown in this release.

Another PAD used in this release is the age code, which is a single letter that relates to the time period in which the property was built, for example, between 1993 and 1999. In this release, this time period is described as the ‘build period’. If a property has no age code recorded, it is counted as having an unknown build period. The look-up table in appendix 2 shows the age codes and their associated build periods.

At the introduction of the 1993 Council Tax Valuation List, most records were held in paper format. The VOA has been continually working to update and improve the accuracy of the Council Tax Valuation Lists and, by 31 March 2004, were able to record the property type of most of these properties electronically in the VOA’s administrative database.

In April 1993, 35% of properties had an unknown property type, 2% of properties had an unknown number of bedrooms and 37% of properties had an unknown build period.

Since March 2014, the amount percentage of unknown property type, bedrooms and build period has reduced to less than 1% in each category.

3.5 Properties with an Improvement Indicator

If a property has been improved or extended since it was placed in a Council Tax band, the VOA cannot review the banding to take account of the alterations until the property is sold. These properties are flagged with an ‘Improvement Indicator’ on the Council Tax Valuation Lists. This means that the PADs held on the VOA’s administrative database for properties with an Improvement Indicator may not reflect the current property details. Once a sale takes place, the banding will be reviewed and the PADs may be updated.

3.6 Effects of boundary changes on the Council Tax lists

When changes to the boundaries of local authorities result in a large number of properties moving from one billing authority to another, the VOA processes these changes by removing these properties from the Council Tax Valuation Lists. The properties are then reinserted into the list with the property’s new billing authority. This process accounts for the large number of insertions (table CTSOP5.0) and deletions (table CTSOP6.0) due to boundary changes that occurred between 1994-95 and 1997-98.

4. Data quality

4.1 Suitable data sources

The information supplied in the tables are based on administrative data held within the VOA operational database. Because it is a statutory requirement of the VOA to maintain accurate valuation lists, the data are considered accurate. However, while the VOA actively seeks to maintain accurate Valuation Lists for Council Tax bandings, some reliance is placed upon the taxpayer to notify the VOA of any inaccuracies to their entry in the Valuation List and billing authorities to notify the VOA of any changes (including new builds, demolitions or alterations).

There is some uncertainty and variability in this process and all administrative data may be subject to processing and system errors. Consequently, although the VOA has made every effort to ensure accuracy of the data underpinning this publication, it is possible that some errors remain. We reflect this by rounding counts to the nearest 10 and suppressing counts lower than 5.

4.2 Assured quality

Our quality assurance follows the approach set out in the VOA Quality Policy.

As part of the production of this publication, quality assurance takes place:

• during the valuation of properties
• as part of the creation of the data which underpins the publication
• as part of the coding which produces the publication outputs
• as part of automated and manual checks of outputs
• using a comprehensive QA Check List and a QA Issues Log

5. Uses of the data

This publication is released in support of making the VOA’s data more accessible as well as presenting consistent information to assist users conducting their own analysis of VOA data. The data will also be used to inform government policy, respond to Freedom of Information requests and to parliamentary questions as well as to conduct operational analyses to support the VOA.

The statistics in this publication relate to England and Wales only. Property valuations are not carried out by the Valuation Office Agency (VOA) in Scotland and Northern Ireland, where the valuation law and practice differ from England and Wales.

The VOA welcomes feedback from users on the information provided in the release. Please forward any comments to the VOA statistics team.

6. CSV metadata

Files which provide the variable names and descriptions appearing in the CSV files are included in this release; they can be found within the ‘CSV Metadata’ zip file on the release page.

7. Timeliness and punctuality

Timeliness refers to the lapse of time between publication and the period to which the data refer. Punctuality refers to the gap between planned and actual publication dates.

This release is published on an annual basis. The data extract for all tables was taken on 31 March 2024. This publication is published within 4 months of the data extract date.

This publication is released annually, in the summer. Details of any changes to the publication will be announced on our schedule of updates and announcements page.

Releases are always published on pre-announced dates at 9:30am. Pre-announcement of the precise date occurs up to four weeks before publication.

8. Relevance

Relevance is the degree to which statistical outputs meet users’ needs.

It is important that the statistics produced meet the needs of users, both in coverage and in content. These statistics evolved largely in response to Freedom of Information requests and Parliamentary Questions and were further developed with input from a CT Statistics Advisory Panel, which involved key users of the data.

9. Coherence and comparability

Coherence is the degree to which data that are derived from different sources or methods, but refer to the same topic, are similar. Comparability is the degree to which data can be compared over time and domain, for example, geographic level.

This release contains figures for 1993 to 2024. Figures for 1993 to 2023 have previously been published and are updated in this release. These statistics have been produced from the same source and use a coherent and consistent methodology. They can be compared with previous releases with one exception: a methodology change made in 2020 means that statistics in tables CTSOP3.0, CTSOP3.1, CTSOP4.0 and CTSOP4.1, which present the number of properties by property attributes, may only be directly compared with these tables in the subsequent releases. For more information, please refer to the ‘Data Quality’ section on page 4 of the background information from the 2020 release. However, because this release contains a complete time series for each of the tables, there should be no need to compare it with any of the previous releases.

As noted in section 3.2, property attributes in this release are the attributes as at 31 March 2024. Therefore, counts of properties by property attributes will not match previous publications.

Tables where different methods of geography assignment have been used should not be compared. See section Assigning geographies for further details.

10. Accessibility and clarity

Accessibility is the ease with which users are able to access the data, also reflecting the format in which the data are available and the availability of supporting information. Clarity refers to the quality and sufficiency of the release details, and accompanying advice.

The release is available free of charge. All official statistics are made available primarily as Excel spreadsheets with comparable tables in CSV format (see section CSV metadata), a background information document, and a statistical summary document.

11. Confidentiality, transparency and security

Access to the data and release during its publication is limited to the statistics production team only. Occasionally, valuation experts may be consulted as part of the quality assurance process. The list of pre-release recipients is published alongside the release.

Further information can found within the VOA Confidentiality and Access policy.
