By the CouncilData research team. Where this guide cites a figure, it comes from our verified dataset of all 350 UK councils — every record source-linked and dated.
The figures on this site — and in our calculator — are the full charge for a home with two or more counted adults. Many households should be paying less. These are the reductions that matter, roughly in order of how often they are missed.
Single person discount — 25%
Live alone, or are the only counted adult? Your bill drops by a quarter. The word counted does the work: full-time students, apprentices under certain schemes, live-in carers, and people with a severe mental impairment are all disregarded. A parent living with a student son or daughter, for example, usually qualifies.
Student households — exempt
If every resident is a full-time student, the property is exempt. Mixed households get the 25% discount if only one non-student adult remains. Halls of residence are exempt automatically.
Disability band reduction
If your home has been adapted for a disabled resident — an extra bathroom or kitchen, or space for wheelchair use indoors — the bill is charged as if the home were one band lower (Band A homes get a proportionate reduction). Combined with the ninths arithmetic, that is typically a cut of about 11–17%.
Council Tax Reduction schemes
Every council runs a means-tested reduction scheme (sometimes called Council Tax Support) that can reduce a bill to zero for low-income households. Schemes vary council by council — apply directly through yours; find its official page linked from its CouncilData page.
Going the other way: premiums
Councils can now charge extra on top of the standard bill: up to double for second homes in much of the UK, and escalating premiums on long-term empty homes. If you are comparing areas before a move, the comparison tool shows the standard charge — check the council's own page for premium policies, which are linked from every council page here.
The 25% single person discount is worth about £584.29 a year on the average UK Band D bill of £2,337.15.
Every one of the 350 UK billing authorities runs its own Council Tax Reduction scheme — the rules differ council by council, which is why no single national answer exists.

How much is the single person discount worth in 2026/27?+
25% of your bill. On the UK average Band D charge of £2,337.15, that is about £584.29 a year — the single most valuable discount most eligible people forget to claim after a change in household.
Can council tax discounts be backdated?+
Generally yes, where you can evidence eligibility for the earlier period — councils differ in how far they will go back, so claim promptly and provide dated proof. A backdated single person discount after a partner moves out is one of the most common successful claims.
Who gets the 25% single person discount?+
Anyone who is the only adult counted as resident in their home. Some adults are 'disregarded' — full-time students, live-in carers, people with a severe mental impairment — so a household can qualify even with more than one adult living there.
Do students pay council tax?+
A household where everyone is a full-time student is exempt entirely. If one non-student adult lives with students, the bill is charged with a 25% discount.
What if I can't afford my council tax?+
Every council runs a Council Tax Reduction (or Support) scheme that can cut bills by up to 100% depending on income. Apply through your own council — the schemes are local and means-tested.
