Council Tax Single Person Discount: The Complete 2026/27 Guide
If you are the only adult living in your home, you are likely entitled to a 25% discount on your Council Tax bill — but it usually has to be claimed, not applied automatically. This pillar guide explains who qualifies, what a "disregarded person" is, how to apply, whether you can backdate a claim, and what happens if your household changes.
The 25% Discount
If you are the only adult living in a property as your main home, you are entitled to a 25% discount on your Council Tax bill for that property. The discount applies to the full annual charge for your property's valuation band and is not means-tested — it is available regardless of income or savings, unlike Council Tax Reduction, which is a separate, income-based scheme that can be claimed in addition where eligible.
How to Apply
In most areas the single person discount is not applied automatically — you need to apply to your local council, usually online through their Council Tax portal or by phone. Councils periodically review existing discounts (for example by writing to check your circumstances have not changed), but a new claim generally needs to be made by the resident rather than being picked up automatically when someone moves house or a household member leaves.
Disregarded Persons
A disregarded person lives at the property but is not counted as a resident adult for Council Tax discount purposes. Common categories include:
- Full-time students (and some student nurses)
- Most apprentices on recognised training schemes
- People classed as severely mentally impaired
- Live-in carers who meet specific residence and hours conditions
- 18 and 19 year olds still in full-time education
- Some people in certain types of care home or hospital accommodation
If a property has two resident adults but one falls into a disregarded category, the household can still qualify for the 25% single person discount, as if only one adult lived there.
Living with a Full-Time Student
If you live with a full-time student, you can still claim the 25% single person discount because the student is disregarded from the resident-adult count. Where every adult in a property is disregarded — for example, a household made up entirely of full-time students — the property may instead qualify for a full Council Tax exemption rather than the 25% discount, since there is no non-disregarded resident adult liable for the tax at all.
Reporting Household Changes
You must tell your council promptly when another adult who is not a disregarded person moves in and starts treating the property as their main home, since this normally ends your entitlement to the discount from that date. Failing to report the change in good time can lead to a backdated bill covering the period you were not entitled to the discount, and in some cases an additional penalty for the delay in reporting.
Backdating a Claim
Many councils will backdate a successful single person discount claim to the date you actually became the only qualifying adult resident, provided you can demonstrate you met the conditions throughout that period. Backdating policies and time limits vary between local authorities, so if you think you may have missed out on the discount in the past, it is worth applying and specifically asking the council whether backdating is available in your case.
Second Homes and Empty Properties
The single person discount applies to your main home, where you are the only qualifying resident adult. A second home you own or rent but do not live in as your main residence is treated differently, since no one is permanently resident there for the purposes of this discount, and it is not eligible in the same way. Many councils instead apply a Council Tax premium — an increased charge — on second homes and on properties left empty for an extended period, so second-home owners should not assume any single-occupancy-style relief will apply.
Discount Fraud and Penalties
Continuing to receive the single person discount after another qualifying adult has moved in, without notifying the council, is a form of Council Tax discount fraud. Councils use data-matching checks — for example against the electoral register, credit reference data and other public records — to identify potentially incorrect claims. Someone found to have wrongly claimed the discount can be billed for the backdated amount owed and, in serious or repeated cases, may face a financial penalty or, in rare cases, prosecution.
Combining with Other Reductions
You cannot combine the single person discount with another discount that is also based on the number of resident adults, since both would be calculated on the same underlying basis. However, the single person discount can generally be claimed alongside Council Tax Reduction — a separate, income-based scheme for people on low incomes — since the two are assessed under different rules and can reduce your bill together where you qualify for both.
