## Quick answer

Single person discount reduces council tax bill by 25% if you live alone or only count adult disregarded persons — apply to council, not automatic everywhere.

Adult children and lodgers usually end single person discount eligibility. Second homes and empty properties face premiums in many council areas. This guide explains who qualifies and how to apply for the 25% reduction.

## Key facts

- 25% discount if only one adult counts for council tax in property
- Full-time students, severe mental impairment and some carers disregarded — may retain discount with two physical adults
- Apply to local council — backdate usually to start date if prompt
- Second home surcharges and empty property premiums separate from single person rules

## Who counts as adult

Generally anyone aged 18 or over counts as an adult for council tax unless they fall into a disregarded category. Full-time students must be on a qualifying course to be disregarded.

Lodgers and boarders usually count as a second adult, which ends the single person discount. Subletting rules vary between councils.

## Applying

Apply through your local council's online form with tenancy or household details. Processing usually takes a few weeks, and backdating to your eligible start date is often possible if you apply promptly.

Failing to notify the council when a second adult moves in risks a backdated bill plus a potential fraud investigation. Report changes promptly.

## Other reductions

Council tax support for low income is a separate means-tested reduction from the single person discount. Claim through your council if you struggle to pay.

A disabled band reduction may apply if your home has been adapted for a disabled resident. This can drop your band by one rather than giving a percentage discount.

## Frequently asked questions

### Is single person discount automatic?

No in most councils — you must apply for the discount. Many councils will backdate to your eligible date if you apply promptly after becoming the sole adult.

### Does a lodger end the discount?

Usually yes if the lodger is an adult, though some councils have specific rules for Monday-to-Friday lodgers who live elsewhere at weekends. Contact your council to confirm how they treat part-week lodgers.

### Can students living with me keep discount?

Full-time students are disregarded for council tax purposes. You may keep the 25% single person discount if the only other adults in the home are qualifying students.
