Single Person Council Tax Discount: Who Qualifies and How to Claim

The 25% Single Person Discount

Council tax is calculated assuming at least two adults live at a property. If only one qualifying adult lives there, you pay a 25% reduced rate. On the average UK council tax bill of around £1,800/year (2025/26 Band D):

Actual saving depends on your council and band — see your bill for exact figures.

Who Qualifies

The single person discount applies if only one adult lives at the property. Adults who are 'disregarded' for council tax purposes don't count — see below.

You get the 25% discount if:

• You're the only adult aged 18+ in your home
• You live with people who are all 'disregarded' (see below)
• Your partner moves out or passes away and you're now the only adult

You do NOT get the 25% discount if:

• You live with one or more other qualifying adults (spouse, adult children, flatmates, etc.)
• The other adult is visiting — they don't count as normally residing there

Who Is 'Disregarded' for Council Tax?

Some people living at a property are not counted as adults for council tax. If every adult in a household is disregarded, you still qualify for the single person 25% discount — even if you're not technically living alone.

Example: You live with your adult child who is a full-time university student. Your child is disregarded. If you're the only non-disregarded adult, you receive the 25% discount.

How to Claim

The process is straightforward but must be initiated by you — councils do not automatically grant the discount.

Step 1: Contact your local council

Find your local council at gov.uk/find-local-council. All councils now have online portals for applying for council tax discounts. You'll typically need:

• Your council tax reference number (on your bill)
• Your name and address
• Date you became the sole occupant

Step 2: Provide evidence if required

Most councils accept your self-declaration. Some may ask for:

• A letter confirming your single occupancy
• Evidence of a former occupant's new address (if they've moved out)
• Student exemption certificate (for student disregards)

Step 3: Check your updated bill

Once processed (usually within 2–4 weeks), your council will issue a revised bill showing the 25% reduction. If you're on Direct Debit, your monthly payment will be reduced automatically.

Backdating the Discount

If you've been living alone and haven't claimed the discount, you may be able to claim it retrospectively. Most councils can backdate to when you moved in alone or when the second adult left, subject to:

• You being able to confirm the date
• The council accepting your evidence
• Local council policy on backdating (varies — usually 12 months, sometimes longer)

If a partner passed away, the discount usually applies from the date of death. Contact your council promptly — you'll likely also have an exemption for the first 6 months of a property left empty after a bereavement.

Other Council Tax Discounts and Reductions

What If You Live With Someone Part-Time?

Part-time residence is a grey area. Someone who splits their time between two properties is generally considered to have a main residence at one address. If they're also registered at your address but primarily live elsewhere, they may not count as normally residing at your property.

You should contact your council and explain the situation honestly. Using the wrong discount is fraud — but genuine part-time arrangements can often be clarified to determine the correct position. Evidence of dual addresses (electoral roll, bank statements, etc.) helps.
