Council Tax Single Person Discount: How to Claim Your 25% Reduction in 2026

If you live alone, or if you are the only adult in your home, you are almost certainly entitled to a 25 per cent reduction on your council tax bill. This is one of the most widely applicable council tax discounts available, yet a significant number of people who qualify either do not know about it or have not applied. Here is everything you need to know about the single person discount in 2026.

What Is the Single Person Discount?

Council tax is calculated on the assumption that at least two adults live in a property. The single person discount reduces the bill by 25 per cent when only one adult is resident and liable to pay council tax. It applies regardless of the value of your property or your income level. You do not have to be single in the relationship sense — the discount applies to anyone who is the sole adult occupant, including couples where one partner lives elsewhere and only one is resident at the property.

Who Counts as an Adult for Council Tax Purposes?

Not all residents count as adults for council tax purposes. Certain categories of people are “disregarded” — meaning they are ignored when counting the number of adults in a property. If everyone except you is disregarded, you are treated as the sole adult and qualify for the 25 per cent discount even if other people live with you.

People who are disregarded include:

• Full-time students (enrolled on a qualifying course at a recognised institution)
• Student nurses
• Youth trainees and apprentices on certain qualifying schemes
• People with severe mental impairment (see below)
• Care workers employed by certain organisations
• People in prison or detained in hospital under mental health legislation
• Members of international headquarters and defence organisations
• 18- and 19-year-olds in full-time education who are not students in the main tax sense
• Foreign language assistants registered with the British Council

If you share a home with someone who falls into one of these categories and no other non-disregarded adults are present, you qualify for the single person discount.

How to Apply for the Single Person Discount

The discount is not applied automatically. You need to tell your council that you qualify. The process is straightforward:

1. Contact your council’s revenues or council tax team, either online, by telephone, or in writing.
2. State that you are applying for a single person discount and confirm that you are the only adult resident at the property (or the only non-disregarded adult).
3. Your council may ask for evidence in some cases — particularly if you moved from a property where two adults were registered.
4. Once approved, the discount is applied to your bill from the date you moved in alone, or from the date your circumstances changed.

Most councils now have an online form. Some will apply the discount from the start of the financial year if you notify them promptly; others will backdate it to when you became eligible. Ask your council about backdating when you apply.

What If You Have Been Overpaying?

If you have been paying full council tax when you should have been receiving the single person discount, you can claim a refund for the period you were incorrectly charged, subject to the council’s backdating policy. Contact your council in writing, explain when you became eligible, and ask for a credit or refund for the overpayment. Most councils will backdate by at least a year; some will go further depending on the evidence you can provide.

What Happens If Your Circumstances Change?

You are legally required to notify your council if your circumstances change in a way that affects your entitlement to the discount. If another adult moves in, you must inform your council promptly. Failing to do so — and continuing to claim the discount — can result in a penalty notice and a demand for repayment of the discount received while you were no longer eligible.

Common changes to report include:

• A partner, family member, or friend moving in
• A student who was disregarded completing their course and no longer being in full-time education
• A disregarded person’s circumstances changing so they no longer qualify for disregard

If you are unsure whether someone who moves in would affect your discount, contact your council’s revenues team and ask before assuming either way.

The Single Person Discount and Universal Credit

If you receive Universal Credit, you may also be entitled to council tax reduction (council tax support) from your local council, which is a separate and potentially larger reduction based on your income and circumstances. The single person discount and council tax reduction can be claimed at the same time — they stack. If you qualify for both, you could be paying significantly less than the standard council tax bill.

Empty Properties and Second Homes

The single person discount applies to your main residence. It does not apply to empty properties or second homes — different rules apply to those, and many councils now charge a premium on long-term empty properties. If you have a second home where only one adult stays, the rules vary by council.

Checking Your Current Bill

Look at your current council tax bill. If it does not show a single person discount and you believe you qualify, contact your council straightaway. Given that the discount is worth 25 per cent of your annual bill — typically £400 to £600 per year depending on your property band and area — it is well worth claiming.
