Millions of UK households are overpaying council tax simply by not claiming discounts and exemptions they already qualify for. None of these apply automatically — here's every one worth checking.
Discounts vs exemptions: what's the difference
A discount reduces your bill by a percentage (usually 25% or 50%). An exemption removes the bill entirely for as long as you qualify. Neither is applied automatically — you have to actively apply to your local council for both, even if your circumstances clearly qualify.
Single Person Discount — 25% off
If you're the only adult in your household who "counts" for council tax purposes, you get 25% off your bill. On the England average Band D bill of £2,392 (2026/27), that's roughly £598 a year. Some adults are automatically "disregarded" and don't count toward the total — so you can still qualify even if more than one adult lives in the property:
- Full-time students
- People with a certified severe mental impairment (SMI) — this includes all forms of dementia and Alzheimer's, and is one of the most commonly missed discounts in the UK
- Live-in carers who aren't the spouse, partner, or parent of the person they care for
- People under 18, and some apprentices and trainees
Example: a couple where one partner has a doctor-certified SMI (such as dementia) — the other partner still gets the 25% single person discount, because the SMI partner is disregarded from the count entirely.
Full exemptions
- All-student households — if every occupant is a full-time student, the property is fully exempt. You'll need a certificate from your university or college confirming full-time status.
- Severe mental impairment — if every remaining occupant qualifies as SMI, the bill can drop by 50% or be fully exempt, depending on the household.
- Certain empty properties — some empty homes qualify for a temporary exemption; apply within three months of the property becoming empty, with supporting evidence.
Disability Band Reduction
If your home has certain adaptations for a disabled resident (extra space for a wheelchair, an additional bathroom or kitchen for their needs), your bill can be charged at the band immediately below your actual valuation band. For a Band D property, that's roughly £266 a year in savings at the 2026/27 England average. Band A properties get a reduction equivalent to one-ninth of the Band D rate instead, since there's no band below A.
How to apply
Contact your local council directly — most offer an online form. Automatic discounts (single person, disability band) typically need evidence of your circumstances. Council Tax Reduction (a means-tested benefit, separate from these discounts) usually takes 4–6 weeks to process once you submit proof of income and savings.
If your council refuses
Write to the council explaining why you disagree, and ask them to reconsider. They should reply within 2 months. If you still disagree with their decision, you can appeal to the Valuation Tribunal — see our Council Tax Appeal Guide for the full process.
