How council tax bands are set
In England and Scotland, every domestic property was placed into one of eight valuation bands (A to H) based on its estimated market value on 1 April 1991. Wales uses nine bands (A to I) based on 1 April 2003 values. These valuations were carried out by the Valuation Office Agency (VOA) and, crucially, have not been updated since, even though property prices have changed enormously in the intervening decades.
This means two similar houses on the same street can sometimes sit in different bands if one was extended or altered before the valuation date, or if the original assessment was simply inaccurate. Your band determines what proportion of the 'Band D' charge you pay: Band A properties typically pay two-thirds of the Band D rate, while Band H properties pay double. Local authorities then multiply this ratio by their own Band D charge, which is set annually and varies significantly between councils.
Who sets the actual amount you pay each year
Your final bill is not decided by the VOA but by your local council, and often by several bodies combined. A typical bill layers together charges from the county or unitary council, a district council where applicable, the local police and crime commissioner, a fire authority, and in many areas a parish or town council precept. Each of these bodies sets its own amount, and your council simply collects the total on their behalf.
Under rules confirmed by the Department for Levelling Up, Housing and Communities (now part of the Ministry of Housing, Communities and Local Government), most English councils can raise general council tax by up to 2.99% and adult social care precepting authorities by an additional up to 2% without triggering a local referendum, though some councils have been granted higher caps in recent years due to financial pressure. This is why bills can rise by different percentages across neighbouring authorities even though the banding system is identical.
A worked example: Band D in two different areas
Imagine a Band D property in Council A, where the total precept for 2026/27 (council, police, fire) comes to £2,150 for the year. A near-identical Band D property in Council B, with a higher social care precept and a separate town council charge, comes to £2,340 for the year, a difference of £190 despite both being 'Band D' properties. This gap arises entirely from local decisions layered on top of the same national banding structure.
If you live in a Band B property in either area, you would pay 7/9ths of the Band D figure (the standard ratio), so in Council A that would be roughly £1,672 and in Council B roughly £1,820. None of this is affected by your income; council tax is a property-based charge, not an earnings-based one, which is why it can feel disproportionately heavy for lower earners in higher-banded homes.
Checking and challenging your band
You can check your council tax band for free on the GOV.UK council tax band checker, which draws on VOA data for England and Wales, or via the Scottish Assessors Association website for Scottish properties. If you believe your property is in the wrong band, for example because it was banded incorrectly at the outset or comparable neighbouring properties are in a lower band, you can ask the VOA to review it, though be aware a review can result in your band moving up as well as down.
It is also worth checking whether you qualify for a discount or exemption, such as the single person discount (25% off) if you live alone, or support if someone in the household has a disability requiring extra space. Because council tax sits alongside other fixed household costs, it is often easier to plan for changes when you look at your full monthly budget together, including take-home pay after tax and National Insurance, rather than in isolation.

FAQ
Frequently asked questions
Short answers first. Open the question if you want the detail behind the result.
How do I find out my council tax band?
You can check for free using the GOV.UK council tax band checker for England and Wales, or the Scottish Assessors Association website if your property is in Scotland. You'll need your postcode or address to look it up.
Can my council tax band change if I extend my house?
Generally, improvements made by the current owner do not trigger a revaluation until the property is sold, at which point the new band based on the improved value applies to the next owner, not immediately to you.
Is council tax based on my income?
No. Council tax is based on the estimated 1991 (England/Scotland) or 2003 (Wales) value band of your property, not on your income. However, income-related support such as Council Tax Reduction schemes may reduce what you owe if you're on a low income.
Why did my council tax rise by a different percentage to my neighbour's council area?
Each local authority, police and crime commissioner, and fire authority sets its own precept independently, and some councils have been given permission to raise bills by more than the standard referendum threshold due to financial pressures, so increases vary by area.
