Part of: UK Council Tax 2026 — Complete Guide → Council Tax Calculator UK 2026 — Estimate Your Annual Bill
TL;DR: Your Council Tax band is specific to your property, not your postcode. Properties in the same postcode can be in different bands if they differ in size, layout, or condition as valued in April 1991. Find your property's band at gov.uk/council-tax-bands (England and Wales) or saa.gov.uk (Scotland). Then find your council's 2026-27 Band D rate on the council's website to calculate your approximate annual charge.

How the Postcode-to-Council Mapping Works
The first step in finding your Council Tax information from a postcode is identifying which billing council is responsible for your address. This is done through gov.uk/find-local-council, the official Cabinet Office tool:
1. Enter your postcode.
2. The tool returns your billing council (and, where relevant, your county council and other local bodies).
3. Click through to the billing council's website to find Council Tax rates and how to apply for discounts.
This mapping is almost always straightforward - most postcodes fall entirely within one billing authority. Postcodes that straddle a council boundary are extremely rare (typically affecting fewer than a handful of properties nationally) and are usually resolved by providing the full address including the house number.
Why Your Band Is Property-Specific, Not Postcode-Specific
Council Tax bands are assigned to individual properties by the Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) based on each property's estimated April 1991 market value. The Valuation Office assesses properties individually, taking into account:
- Size (floor area)
- Type (terraced, semi-detached, detached, flat)
- Location within the street (end of terrace vs mid-terrace)
- Aspect and orientation
- Any extensions or improvements completed before 1991
- Condition in 1991
Two properties in the same postcode - even next-door neighbours - can be in different bands if their 1991 values differed. For example, a corner plot property with a larger garden and an extension may be Band D while the adjacent mid-terrace without an extension is Band C.
How to Find Your Property's Band
England and Wales: Go to gov.uk/council-tax-bands. Enter your postcode and then select your specific address from the list. The result shows your band (A to H in England; A to I in Wales).
This lookup is the official Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) published list. It is free, requires no registration, and shows the band for every residential property in England and Wales.
Scotland: Go to saa.gov.uk and select "Council Tax." Enter your Scottish postcode and address. The Scottish Assessors Association maintains the Scottish valuation roll for all 32 council areas.
Parish Precepts: Why Two Postcodes in the Same District Can Have Different Total Bills
In rural and some semi-rural parts of England, civil parish councils levy a precept on top of the billing authority's Council Tax. This creates genuine variation in Council Tax total between different addresses within the same billing district:
Example: Two properties in the same district council area but different civil parishes. Property A is in a parish that levies a £120/year Band D precept. Property B is in a parish with no precept. Both pay the same district and county Council Tax, but Property A pays £120/year more.
Parish precept information is typically shown on the demand notice. To find the precept for a specific address, look at the billing council's published schedule of parish precepts for 2026-27, available on the council's website.
Properties in metropolitan borough areas, inner London boroughs, and other urban non-parished areas have no parish precept.
The GLA Precept in London: Same for Every London Property
In London, the Greater London Authority (GLA) charges a single precept across all 33 London boroughs. In 2026-27, this is approximately £471 at Band D.
Every residential property in London (whether in Westminster, Hackney, Bromley, or any other London borough) pays the same GLA precept at the applicable band fraction. There is no variation between London boroughs for the GLA element.
The total London Council Tax bill = Borough's Band D rate + GLA Band D rate (~£471), multiplied by the band fraction.
Combined Authority Precepts Outside London
England's 10 mayoral combined authorities charge precepts across their areas:
- Greater Manchester: approximately £114 at Band D
- West Yorkshire: approximately £24 at Band D
- South Yorkshire: approximately £25 at Band D
- West Midlands: approximately £30-40 at Band D
- North East: approximately £20-30 at Band D
- Tees Valley: approximately £10-20 at Band D
- West of England: approximately £15-25 at Band D
These precepts apply uniformly within the combined authority area. Unlike parish precepts (which vary by parish), the combined authority precept is the same for all postcodes within the relevant metropolitan area.
Worked Examples: 5 Postcodes in England
Example 1 - NW1 4RY (Camden, London):
Camden Band D approximately £1,650; GLA precept approximately £471; combined Band D approximately £2,121. Band C (8/9): approximately £1,885/year.
Example 2 - NG1 2DT (Nottingham City):
Nottingham Band D approximately £2,439. Band D: approximately £2,439/year. Band A (6/9): approximately £1,626/year.
Example 3 - SK1 3NE (Stockport, Greater Manchester):
Stockport Band D approximately £2,108 + GMCA precept approximately £114 = combined Band D approximately £2,222. Band E (11/9): approximately £2,715/year.
Example 4 - OX1 4BH (Oxford, in parish, two-tier Oxfordshire):
South Oxfordshire/Oxford City Band D approximately £2,050 + any parish precept (may be £0 in central Oxford which is non-parished). Band B (7/9): approximately £1,594/year.
Example 5 - PL1 2PP (Plymouth, unitary):
Plymouth Band D approximately £2,250. Band A (6/9): approximately £1,500/year.
All examples are approximate based on 2026-27 published rates. Verify with the specific billing council.
The Limitations of Third-Party Postcode Calculators
Several property portals and comparison websites offer Council Tax lookups by postcode. These are useful for quick estimates but have systematic limitations:
Stale Band D figures: Property portals typically display the band from the Valuation Office (correct) but use Band D figures from previous years if their database has not been updated. This understates the current bill by the amount of the year-on-year increase.
Missing precepts: Most third-party tools show only the council element and miss parish precepts and combined authority precepts. This can understate the total charge by £20 to £200/year.
Band is property-specific: A postcode search showing a band for "typical properties in this postcode" may not be accurate for a specific property which may have a different band.
For authoritative information: gov.uk/council-tax-bands for the band (England/Wales); billing council's website for the 2026-27 Band D rate; demand notice for the precise bill amount.
How the ONS Uses Postcode Council Tax Data
The Office for National Statistics (ONS) uses Council Tax billing council data, aggregated at local authority and postcode area level, for several purposes:
Local area statistics: The ONS publishes sub-regional statistics on Council Tax levels, collection rates, and average bills. These use local authority-level data rather than property-level data.
Housing market analysis: Postcode-level Council Tax band data feeds into ONS analysis of housing stock characteristics and affordability. The ONS Neighbourhood Statistics tool and related datasets incorporate band distribution data.
MHCLG annual statistics: MHCLG collects Council Tax data from all billing councils annually and publishes national and local-authority-level statistics. These include Band D rates, exemption volumes, reduction scheme coverage, and collection rates.
The History of the Postcode-to-Council Mapping
The current postcode-to-council mapping is maintained by the ONS's Open Geography portal and is updated periodically. In some cases, postcodes have been revised, local authority boundaries have changed, or new housing developments have been built on the edge of a council boundary.
The most significant recent boundary changes affecting Council Tax were the creation of new unitary authorities in areas like Cumberland and Westmorland (2023), which merged several district and county councils. Some postcodes that previously crossed the boundaries of these now-merged areas may have a simplified mapping.
MHCLG maintains the definitive list of billing authorities for Council Tax purposes. Changes to billing authority boundaries require secondary legislation and are relatively rare.
Using Rightmove, Zoopla, and Other Property Portals
Property portals typically display Council Tax information for listed properties. However, there are systematic issues with relying on portal data:
Band source: Most portals retrieve the band from the Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) data, which is generally accurate. However, if the band was successfully challenged and reduced after the portal last updated its data, the portal may show the old (higher) band.
Annual charge shown: Portals typically show a Council Tax charge alongside the band. This charge is often based on the previous year's Band D rate (not the current year), and frequently does not include the parish precept or combined authority precept. The charge shown on a portal listing may be £100 to £300 lower than the actual current-year total bill.
For property purchase decisions, always verify the current band at gov.uk/council-tax-bands and the current year's total charge with the billing council directly.
Frequently Asked Questions
Can I look up my neighbour's Council Tax band?
Yes. The Council Tax valuation list is a public register. Gov.uk/council-tax-bands shows the band for every residential property in England and Wales. Entering your neighbour's address returns their band. This information is publicly available under the Local Government Finance Act 1992.
My property is a new build - why doesn't it show on gov.uk/council-tax-bands?
New build properties are assigned a Council Tax band by the Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) after the completion is notified. There is typically a delay of 30 to 90 days between completion and the band being added to the public valuation list. The Valuation Office uses comparable evidence from similar nearby properties to assign the band. Check the gov.uk lookup again after a few months. In the meantime, the billing council may issue a provisional or estimated-band demand while the official band is being confirmed.
My postcode covers properties in two different billing authorities - how do I know which one applies to my property?
Use gov.uk/find-local-council and enter your full postcode. If the postcode returns an ambiguous result or displays multiple possible councils, enter the postcode together with the house number or the first line of the address to narrow down the result. Gov.uk's local council finder should resolve any boundary-spanning postcode to the correct billing authority for your specific address. In very rare edge cases, contact both candidate councils and ask which one holds a Council Tax record for your specific address.
Council Tax seems much cheaper in my area than in nearby areas - why?
Council Tax rates vary significantly between billing authorities based on the council's spending decisions, grant funding from central government, population size, and service delivery costs. A council receiving higher central government grant income needs less Council Tax income from local residents; a council with lower grant and higher per-resident service costs sets a higher Band D rate. The variation can be over £1,000 per year at Band D between the cheapest (Westminster, historically) and the most expensive authorities. Rural and small councils often face higher unit costs because infrastructure and services cost more per resident to provide than in densely populated urban areas.
Does the ONS use postcode data for Council Tax research?
Yes. The ONS (Office for National Statistics) uses billing council data aggregated at postcode sector and local authority level for official statistics on Council Tax levels, coverage, and collection rates. The ONS does not publish individual property-level Council Tax data, but uses local authority-level aggregates in its local area statistics, regional comparisons, and housing market analysis publications.
How we verified this
The gov.uk/council-tax-bands lookup is the official Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) published band register. Gov.uk/find-local-council is the Cabinet Office official local authority finder. GLA precept (~£471 Band D 2026-27) is from the GLA's published budget. GMCA precept (~£114) is from the GMCA's published budget. MHCLG publishes annual Band D statistics for every English billing authority. ONS uses local authority Council Tax data in official statistics.
