Council tax single person discount and who counts as an adult

In England and Wales, a household with one countable adult can have 25% off its council tax bill, and 50% off if every adult is disregarded. This guide explains who counts, how to claim and where rules differ.

What the discount is and how it works

Council tax is a local charge on homes in England, Scotland and Wales, set by each council and based on the property's valuation band. A full bill assumes that at least two adults live in the home. The single person discount, sometimes called the single adult discount, reduces the bill when only one adult is counted. According to GOV.UK, if you pay council tax and live alone you get 25% off, and the same 25% applies if you pay the tax and everyone else in the home is disregarded. A disregarded person is someone the law does not count when working out how many adults live in a property. The discount is not automatic: GOV.UK says you must apply for it, even where the other residents are disregarded. This guide covers the 2026/27 council tax year and was checked on 20 October 2026.

Who is not counted as an adult

GOV.UK lists the main groups of disregarded people. They include anyone under 18, full-time students at college or university, student nurses, certain apprentices, people aged 18 or 19 in full-time education, foreign language assistants registered with the British Council, severely mentally impaired people, live-in carers and diplomats. For apprentices, GOV.UK says the employer must confirm that earnings are no more than £195 a week and that the training leads to a recognised qualification. A live-in carer is disregarded only if they look after someone who is not their partner, spouse or child under 18. Each category has its own detailed conditions, and councils may ask for evidence such as a medical certificate. Citizens Advice also lists people who are temporarily away in long-term care or in prison, but its page was last reviewed in 2021, so it can be worth asking your council whether its list has changed.

• Under 18s are never counted.
• Full-time students and student nurses are disregarded.
• Severely mentally impaired people are disregarded if they have a doctor's certificate and receive a qualifying benefit.
• Live-in carers can be disregarded if they are not the partner, spouse or parent of the person cared for.

Other reductions linked to the same rules

If everyone in a home is disregarded, GOV.UK says the bill is cut by 50% rather than 25%. Some households pay nothing at all: GOV.UK says homes where everyone is a full-time student are exempt, and the course must normally last at least one year with at least 21 hours of study a week. For people who are severely mentally impaired, GOV.UK's page on discounts for disabled people says the discount can be 100% if the person lives alone or only with other severely mentally impaired adults or full-time students. Separately, the Disabled Band Reduction Scheme lowers a bill to the next band down where a home has an extra bathroom, kitchen, another room needed by a disabled person or space to use a wheelchair indoors. A Band A property cannot move lower, so it receives a 17% reduction instead.

A worked example

This example uses illustrative figures, not a real council's charges. Suppose a home in a lower band has a yearly council tax bill of £1,800, and one adult lives there. The 25% discount is 0.25 x £1,800 = £450, leaving £1,350 a year, or £112.50 a month if spread over twelve instalments. If a second adult moved in who is a full-time student, the household would usually still qualify, because the student is disregarded. If instead both adults were disregarded, the discount would be 50%: 0.5 x £1,800 = £900, leaving £900. For the Band A reduction, imagine a bill of £1,500: 0.17 x £1,500 = £255 off, leaving £1,245. Councils set their own bills, so the amounts in your area will differ.

Council Tax Reduction and differences across the UK

A separate scheme, Council Tax Reduction, is means-tested, which means it depends on income, savings and circumstances such as children, disability and the benefits received. GOV.UK says it can reduce a bill by up to 100% and that you apply through your local council, because each council runs its own scheme. In Scotland, mygov.scot describes a national Council Tax Reduction Scheme administered by councils, and its list of residents who are not counted includes school leavers under 20 and care leavers under 26, which differs from the England list. Northern Ireland has no council tax. Nidirect explains that bills there are domestic rates, and reliefs such as the Lone Pensioner Allowance, Rate Rebate and Housing Benefit apply instead. For Wales, the Citizens Advice page for Wales gives the same 25% and 50% figures as its England page, but it is an older page, so local checking matters.

Common mistakes and where to get free help

A frequent mistake is assuming the discount applies without a claim, when GOV.UK says it must be applied for. Another is forgetting to report a change, because a discount can stop being due if another adult moves in. Citizens Advice says you should tell the council within 21 days, and that a penalty may apply if you do not. If someone has moved out, Citizens Advice says you can claim the discount from the date they left even if you tell the council later, though it is wise to act quickly. If you disagree with a decision, Citizens Advice explains that you can complain to your council first, and may then be able to appeal to a valuation tribunal. Free, independent help is available from Citizens Advice, and MoneyHelper offers guidance if bills are hard to manage.

Discounts, thresholds and local schemes can change, and councils apply their own evidence rules. It can be worth confirming the details on the official pages linked below and with your local council before relying on any figure here.
