Council Tax Single Person Discount
The single person discount cuts a council tax bill by 25% when only one adult is counted at the property. The rules are simple in principle, but many households miss the discount because some adults are disregarded.
Who qualifies
You qualify if you are the only adult who counts for council tax purposes. You do not always need to live completely alone. Some adults are disregarded, meaning they do not count when the council decides whether the property has one chargeable adult.
- Full-time students
- Some apprentices and youth trainees
- People with severe mental impairment, where certified
- Some live-in carers
- People in prison, except for certain fine/non-payment cases
- 18 and 19-year-olds in qualifying education
How much it saves
The discount is normally 25% off the council tax bill. If your annual bill is GBP 2,000, the discount is worth about GBP 500 per year. The saving scales with the band and local authority charge.
Before applying, check that your band is correct. A 25% discount on the wrong band is still an overpayment. Use the calculator and postcode checker if your bill looks too high.

How to apply and backdate it
Apply through your local council. Most councils provide an online form. You may need your council tax account number, move-in date, and evidence for disregarded occupants.
Backdating is possible where you were eligible earlier but had not claimed. Councils vary in how far back they will go and what evidence they require, so state the date your circumstances changed and keep any tenancy, student, care, or bereavement documents.
Common mistakes
Do not keep claiming after another chargeable adult moves in. Councils verify claims using electoral roll and credit-reference data. Also do not assume that a student, carer, or adult child automatically counts. Check whether they are disregarded under the council tax rules.
