Second Adult Rebate: The Council Tax Discount Most Households Don't Know Exists
Second Adult Rebate can reduce a Council Tax bill when the liable person lives with another adult on a low income who isn't their partner — a different, less well-known discount from the single person's 25% reduction.
A discount that's easy to miss because it's counter-intuitive
Most people are aware of the 25% single person's discount on Council Tax. Far fewer are aware of Second Adult Rebate, which applies to what feels like the opposite situation: you're not living alone, but the other adult (or adults) living with you have a low income and aren't your partner — meaning you still don't benefit from the single person's discount, but you might still be entitled to a reduction based on their circumstances.
How the two discounts differ
| Discount | When it applies | What it's based on |
|---|---|---|
| Single person's discount | Only one adult lives in the property | Automatic 25% reduction, regardless of that person's income |
| Second Adult Rebate | Another adult lives with you, not your partner, on a low income | The second adult's income and circumstances |
The key distinguishing feature of Second Adult Rebate is that it looks at the second adult's financial circumstances, not the liable person's own income — the reverse of how the main, more widely known Council Tax Reduction scheme usually works.

For these purposes, a second adult is generally someone who:
- Lives in the property as their main home
- Is not your partner (spouse, civil partner, or someone you live with as a couple)
- Is not otherwise disregarded for Council Tax purposes (certain groups — for example, full-time students in some circumstances — are disregarded and treated differently, so they don't count as a "second adult" triggering this specific rebate in the same way)
- Has a low income, or receives certain qualifying benefits, that would potentially entitle them to a reduction if they were assessed under the standard rules
Common real-world examples include an adult child living at home who is on a low income, another family member sharing the property, or a friend/lodger with limited income.
Why this is often missed
Second Adult Rebate sits in an awkward gap in most people's understanding of Council Tax discounts: households assume that because more than one adult lives in the property, no discount at all is available (ruling out the single person's discount, correctly), without realising a different discount, based on the other person's circumstances rather than their own, might still apply.
Can you get both types of reduction?
It's generally possible for a household to be assessed for both Second Adult Rebate (based on the second adult's low income) and the standard Council Tax Reduction scheme (based on the liable person's own income), with most councils applying whichever produces the larger reduction for the household — rather than adding both together. Since Council Tax Reduction schemes are administered locally, the precise interaction and application process can vary between local authorities, so it's worth checking directly with your own council rather than assuming a specific national rule applies uniformly.
Regional differences
Council Tax (and the equivalent systems in Scotland and Wales, and rates in Northern Ireland) is administered separately across the different nations and, within England specifically, by individual local councils who can set their own local Council Tax Reduction scheme rules within a national framework. Second Adult Rebate as commonly understood is a feature of some English schemes — if you live in Scotland or Wales, check your own local authority's specific equivalent provisions, since the scheme design and terminology can differ.
Practical steps
- Check your household composition — do you live with another adult who isn't your partner and who has a low income?
- Don't assume no discount is available just because more than one adult lives in your home — Second Adult Rebate exists precisely for this situation.
- Contact your local council directly to check the specific eligibility criteria and application process for Second Adult Rebate (or your council's equivalent scheme), since rules and administration vary locally.
- Ask specifically whether you'd also be assessed under the main income-based Council Tax Reduction scheme, since you may be entitled to whichever produces the bigger reduction.
- Gather evidence of the second adult's income and circumstances in advance of applying, since this is what the assessment is based on, not your own income.
Frequently asked questions
What is Second Adult Rebate?
Second Adult Rebate is a Council Tax reduction available in some circumstances when the person liable for Council Tax shares their home with one or more other adults, on a low income, who are not their partner and who wouldn't otherwise be disregarded for Council Tax purposes — it reduces the bill based on the second adult's low income and circumstances, rather than the liable person's own financial circumstances.
How is Second Adult Rebate different from the single person's 25% discount?
The single person's discount applies when only one adult lives in the property, reducing the bill by 25% regardless of that person's income. Second Adult Rebate applies in the opposite scenario — when there IS another adult living in the property (so the single person's discount doesn't apply), but that other adult has a low income, is not the liable person's partner, and isn't otherwise disregarded — the rebate is based on the second adult's income and circumstances, not the liable person's own income.
Can I claim Second Adult Rebate and single person's discount at the same time?
No — these are mutually exclusive by definition, since the single person's discount requires only one adult living in the property, while Second Adult Rebate specifically requires an additional adult (who isn't disregarded) to be living there — you would apply for whichever one is actually relevant to your household composition, not both.
Is Second Adult Rebate based on my own income or the second adult's income?
It's based on the second adult's (or second adults', if there's more than one) income and circumstances — specifically, whether they are on a low income or receiving certain benefits — rather than the liable person's own income, which is the reverse of how most other Council Tax Reduction schemes work, where it's the liable person's own income that's assessed.
Can I claim Second Adult Rebate and the main Council Tax Reduction (based on my own income) at the same time?
Generally, a household can be assessed for both Second Adult Rebate (based on the second adult's low income) and the main Council Tax Reduction scheme (based on the liable person's own income), and would typically receive whichever produces the greater reduction — check with your local council, since Council Tax Reduction schemes are administered locally and the exact rules and interaction can vary between local authorities in England.
Who counts as a 'second adult' for these purposes?
Broadly, another adult living in the property who is not the liable person's partner (spouse, civil partner or someone they live with as a couple) and who isn't otherwise 'disregarded' for Council Tax purposes (certain groups, such as full-time students, are disregarded and don't count as a second adult for this purpose in the same way) — common examples include an adult child, a friend, or another family member sharing the home.
Does Scotland or Wales have an equivalent to Second Adult Rebate?
Council Tax Reduction schemes are administered separately in England, Scotland and Wales (and Northern Ireland has its own separate rates system), each with their own specific rules — Second Adult Rebate as described is specifically part of some English schemes; check your own local authority's specific Council Tax Reduction or Second Adult Rebate provisions if you live in Scotland or Wales, since the exact scheme design differs.
How do I apply for Second Adult Rebate?
Applications are made through your local council, which administers Council Tax and any local Council Tax Reduction scheme — contact your specific local authority directly, as the application process, evidence required, and exact eligibility criteria can vary between councils.
