TL;DR: Second adult rebate reduces your Council Tax bill based on the income of another adult living with you - not your own income. This means higher-income householders can qualify if they share with a low-income adult. The maximum rebate is 25% - the same as the single person discount. Pension-age householders with adult children on low incomes are the most common beneficiaries in 2026.

What Is Second Adult Rebate?
Second adult rebate (also called alternative maximum Council Tax Reduction) is a Council Tax reduction based on the income of a "second adult" living in your home, not on your own income or means. This makes it fundamentally different from the standard Council Tax Reduction (CTR) scheme, which assesses the claimant's own financial circumstances.
The legal basis is the Council Tax Reduction scheme regulations. For pension-age claimants, the provisions are set out in the nationally prescribed pension-age CTR scheme under the Local Government Finance Act 1992 (Schedule 1A). For working-age claimants, second adult rebate provisions were largely removed from most English local schemes after the 2013 localisation of working-age CTR, though some councils have retained elements.
The second adult rebate system was designed to prevent a specific hardship: a householder who shares their home with a non-partner adult of low income might lose the 25% single person discount (because the second adult removes the "sole occupant" status) without being able to claim CTR based on their own income if their own income is too high. Second adult rebate addresses this gap.
Who Is a "Second Adult"?
A second adult for rebate purposes is any adult aged 18 or over who:
- Lives at the property as their main or sole residence
- Is not your partner or civil partner
- Is not someone who is disregarded for Council Tax purposes (so full-time students, severely mentally impaired adults, and other disregarded persons do not count)
- Is not jointly liable with you for the Council Tax
In practice, the most common second adult scenarios are:
Adult child living with a pensioner parent: An adult son or daughter who has returned home, or who never left, and is on a low income. The pensioner parent is the Council Tax liable person; the adult child is the second adult.
Elderly parent living with an adult child: Where an older parent has moved in with their adult child's household, and the parent is the Council Tax liable person in their own right at the property (unusual but possible in some ownership structures).
Sibling or other relative: A low-income sibling or other relative sharing accommodation with the liable person.
Lodger on a very low income: An unusual scenario, but a lodger who is not disregarded and has a very low income could qualify as the second adult for rebate purposes, though the rebate mechanism is distinct from the lodger's own liability situation.
How the Rebate Is Calculated
The second adult rebate is calculated as a percentage of the Council Tax bill, based on the second adult's income:
Maximum rebate (25%): The second adult is in receipt of Universal Credit, Income Support, Jobseeker's Allowance, or Pension Credit (with no earned income). The rebate is 25% of the Council Tax bill - the same as the single person discount.
15% rebate: The second adult has gross income below a specified weekly threshold (typically in the range of £220 to £250/week gross, though this varies by council scheme and whether it is pension-age or working-age).
7.5% rebate (some schemes): The second adult has gross income above the lower threshold but below a higher threshold.
No rebate: The second adult's income is above the upper threshold.
The rebate is always calculated on your bill (the liable person's bill) - not on the second adult's liability. The second adult has no Council Tax liability in their own right at this address in the standard scenario.
The Better-Off Check: CTR vs Second Adult Rebate
Your billing council is required to assess both the standard CTR (based on your income) and the second adult rebate (based on the second adult's income) and award whichever is higher. This is sometimes called the "better-off check."
For a pension-age householder with a moderate income who would receive partial CTR based on their own circumstances, but whose second adult is on Universal Credit, the second adult rebate may produce a higher reduction (25%) than the means-tested CTR calculation. In that case, the council awards second adult rebate.
In practice, many councils do not run the better-off check prominently in their application processes. If you believe you might qualify for second adult rebate and have not been assessed for it, ask the council's Council Tax team explicitly.
Working-Age Second Adult Rebate: Limited Availability in 2026
When working-age CTR was localised in 2013, most English councils simplified their schemes by removing or restricting working-age second adult rebate. As of 2026:
- The pension-age second adult rebate remains nationally prescribed and widely available.
- Working-age second adult rebate exists in some councils' local schemes but not all. Check your specific council's published CTR scheme document for 2026-27.
If you are working-age and sharing your home with a low-income adult, the primary relief route is the standard means-tested CTR based on your own income. Second adult rebate may be available if your council retains it; ask explicitly.
Second Adult Rebate vs Single Person Discount: Understanding the Choice
A common point of confusion is the relationship between second adult rebate and the single person discount.
The single person discount (25%) applies where you are the only non-disregarded adult at the property. Once a second non-disregarded adult moves in, you lose the single person discount.
Second adult rebate (up to 25%) may then replace it - but only if the second adult's income is low enough. This creates a situation where:
- If the second adult is on UC/IS/PC (low income): You receive 25% second adult rebate. Your bill is the same as it was with the single person discount. Net financial impact of the second adult moving in: zero.
- If the second adult has moderate earned income: You receive 15% second adult rebate. Your bill increases by 10% of the standard charge. You are worse off than when receiving the single person discount.
- If the second adult has higher income: You receive no second adult rebate. You lose the full 25% single person discount and your bill increases by 25% of the standard charge.
This analysis is particularly relevant for pensioners considering whether to allow an adult child to move in. If the adult child is on Universal Credit, the impact on Council Tax is neutral (second adult rebate replaces single person discount). If the adult child is employed, the impact depends on their income.
The MHCLG does not publish national data on second adult rebate uptake separately from CTR, but local council CTR statistics typically include SAR figures in annual reports.
How to Apply
Second adult rebate is typically assessed through the same application process as CTR. Most councils have a single combined CTR application form that includes questions about other adults in the household. When completing the form:
- List all adults in the household.
- For each adult who is not your partner, provide their income details (payslips, benefit award letters).
- Tick any relevant box asking whether you want the council to consider second adult rebate.
- If the form does not ask explicitly, add a note requesting that second adult rebate be assessed alongside CTR.
Processing takes approximately 14 to 28 days. The council will assess both CTR and second adult rebate and award whichever produces the higher reduction.
Evidence required for the second adult:
- Bank statements or wage slips for the second adult (to evidence income)
- Benefit award letters if the second adult is receiving DWP benefits
- Confirmation of the second adult's identity and relationship to you
Pension Credit and Second Adult Rebate
If you receive Pension Credit Guarantee Credit, you qualify for maximum CTR (100% reduction) under the passport rule - which will almost always be more beneficial than the 25% second adult rebate maximum. In this scenario, there is little practical reason to claim second adult rebate.
However, if you receive Savings Credit (the older element of Pension Credit) rather than Guarantee Credit, and your means-tested CTR calculation produces less than 25%, it is worth asking your council to check whether second adult rebate would produce a better outcome.
Frequently Asked Questions
My adult daughter lives with me and is on Universal Credit - can I claim second adult rebate?
Yes, provided you are pension-age and are the Council Tax liable person at the address. If your daughter is on Universal Credit with no earned income, she qualifies as a "qualifying second adult" for the maximum 25% rebate. Apply through your council's CTR form and provide your daughter's Universal Credit award letter as evidence.
I'm working-age - can I still get second adult rebate?
It depends on your council's local working-age CTR scheme. Most English councils removed working-age second adult rebate when CTR was localised in 2013. Some retained it. Check your council's published 2026-27 CTR scheme document or ask the revenues team directly.
If I get second adult rebate, does my adult relative have to pay anything?
No. Second adult rebate reduces your bill as the liable person. The second adult has no Council Tax liability at your address in the standard scenario. The rebate is based on their income, but they pay nothing - it is a benefit that flows to you.
Does second adult rebate apply if I have more than one second adult?
Councils assess the combined income of all second adults in the household. If you have two second adults and one is on a very low income while the other is in full-time work, the higher-income second adult's income typically reduces or eliminates the rebate. Check your council's specific scheme rules. The MHCLG does not publish a separate national breakdown of second adult rebate awards by number of second adults, but local council CTR statistics (published in each council's annual financial reports and the MHCLG CTR data collection) typically include the total number of SAR awards and the average award value, which can help contextualise how the scheme operates locally. The IRRV provides professional guidance to councils on assessing second adult income in multi-adult households.
My adult son moved in last month and my single person discount has stopped - can second adult rebate replace it?
Yes - if your son is on a low income or receives qualifying benefits. Apply for second adult rebate immediately through your council's CTR application. If his income qualifies for the 25% rebate, your bill will be the same as it was with the single person discount. Notify your council of the change of circumstances (son moving in) within 21 days, as required by the Council Tax (Administration and Enforcement) Regulations 1992, and at the same time apply for second adult rebate. The IRRV provides professional guidance to councils on managing single person discount cessation and second adult rebate commencement simultaneously, to avoid creating a gap period in which you pay the full undiscounted rate.
How we verified this
Second adult rebate provisions for pension-age claimants are from the Council Tax Reduction Schemes (Prescribed Requirements) (England) Regulations 2012, which nationally prescribe the pension-age CTR scheme. The Local Government Finance Act 1992 (Schedule 1A) provides the statutory basis. The localisation of working-age CTR (and consequent removal of working-age SAR in most councils) is documented in MHCLG guidance on the 2013 CTR localisation. Income thresholds for second adult rebate bands are from representative council schemes cross-checked against the prescribed scheme. The IRRV provides professional guidance on the better-off check requirement. The DWP provides Pension Credit guidance used in the Pension Credit interaction section.
