Quick summary
A person medically certified as severely mentally impaired is disregarded for Council Tax. If they live alone that usually means a full exemption. If they live with one other adult, a 25 per cent discount. It can often be backdated, and it is worth four figures a year. Most families are never told.
What the disregard is
Council Tax assumes two adults live in a property. Certain people are “disregarded”, meaning the council counts the household as if they were not there.
Someone who is severely mentally impaired is one of those groups. GOV.UK defines this as having a severe impairment of intelligence and social functioning which appears to be permanent, and gives Alzheimer’s disease, Parkinson’s disease, severe learning difficulties and having had a stroke as examples of conditions that may qualify (GOV.UK, Council Tax discounts for disabled people).
The phrase is clumsy and outdated, and plenty of families are put off by it. It is legal terminology rather than a judgement about the person.
What it is worth
Household | Result |
|---|---|
Person lives alone | Exempt. No Council Tax at all |
Lives with one other adult | 25 per cent discount, as the household counts as one adult |
Lives with one other adult who is also disregarded, for example a full-time carer | Exempt, since no countable adults remain |
Lives with two or more other countable adults | No discount, though it is still worth registering the disregard in case circumstances change |
On a mid-band property, a full exemption is commonly worth well over £2,000 a year, and a 25 per cent discount several hundred.
The two things you need
- A certificate from a registered medical practitioner, usually the GP, confirming the severe mental impairment. Surgeries deal with these regularly. Ring and ask for a Council Tax severe mental impairment certificate, using that phrase.
- Entitlement to a qualifying benefit. The list includes Attendance Allowance, the daily living component of Personal Independence Payment, the middle or higher rate care component of Disability Living Allowance, and several others.
The second condition is where most families come unstuck, and it explains the order to do things in. Claim Attendance Allowance first, because it is not means-tested and it is frequently what unlocks this. Our first-month-after-diagnosis guide sets out the whole sequence.
Note the wording: entitlement to a qualifying benefit. Someone over State Pension age who has an underlying entitlement they do not receive in cash can still meet the test, which is worth raising if you are told otherwise.
Backdating
This is the part that turns a useful saving into a significant one.
Councils will often backdate to the date the qualifying conditions were first met, which can be years rather than months. Where a GP is willing to certify that the impairment existed from an earlier date, and the qualifying benefit was in payment then, that is the date to argue for.
Ask about backdating explicitly and in writing. Practice varies between councils, and some will only apply it from the date of the claim unless you press. If a council refuses, ask for the decision and the reasons in writing, then use its complaints process.
Who to apply to
Council Tax is handled by the district, borough or unitary council, which is not always the one that deals with care.
Where you live | Apply to |
|---|---|
Macclesfield, Wilmslow, Handforth, Alderley Edge, Prestbury, Bollington, Knutsford, Mobberley, Chelford, Goostrey, Holmes Chapel, Congleton, Alsager and the surrounding villages | Cheshire East Council, which handles both Council Tax and care |
Buxton, Harpur Hill, Whaley Bridge, Taxal, Chapel-en-le-Frith, Dove Holes | High Peak Borough Council for Council Tax. Care is Derbyshire County Council |
Leek, Meerbrook, Longnor, Hollinsclough, Biddulph, Biddulph Moor | Staffordshire Moorlands District Council for Council Tax. Care is Staffordshire County Council |
Kidsgrove | Newcastle-under-Lyme Borough Council for Council Tax. Care is Staffordshire County Council |
If you ring the wrong one you will be sent elsewhere, which is why our guide to which council does what exists. Note also that local government reorganisation is under way in both Derbyshire and Staffordshire, with new unitary councils expected in 2028.
How to apply, step by step
- Check the qualifying benefit is in place. If not, claim Attendance Allowance first.
- Download the council’s form, usually called a severe mental impairment discount or disregard application.
- Take the medical section to the GP. Some surgeries charge a small fee for completing it; many do not.
- Send it back with evidence of the benefit award.
- Ask in writing for backdating to the date the conditions were first met.
- Keep a copy of everything.
Other Council Tax help worth checking at the same time
- Single person discount, 25 per cent, if they now live alone.
- Council Tax Reduction, a separate means-tested scheme, which Pension Credit can unlock.
- The disabled band reduction scheme, which can move a property down a band where there is an extra bathroom, an extra room used for the person’s needs, or space for a wheelchair indoors. Different from the disregard, and claimable alongside it.
- Empty property exemption, where someone has moved permanently into a care home or in with family to be cared for.
Frequently asked questions
Do you get a Council Tax discount if you have dementia?
If a doctor certifies severe mental impairment and the person is entitled to a qualifying benefit, they are disregarded. Living alone, that usually means paying nothing. Living with one other adult, a 25 per cent discount.
Does a dementia diagnosis alone qualify?
No. Both conditions must be met: the medical certificate and entitlement to a qualifying benefit.
Can it be backdated?
Often yes, sometimes by years, to when the conditions were first met. Ask explicitly, in writing, and be prepared to push.
Will the GP charge?
Some practices charge a small fee for completing the certificate. Set against a potential four-figure annual saving, it is still worth doing.
What if the council says no?
Ask for the decision in writing with reasons. You can challenge it through the council’s process and ultimately the Valuation Tribunal. Citizens Advice and Age UK can help.
Does it apply to other conditions?
Yes. GOV.UK gives Alzheimer’s, Parkinson’s, severe learning difficulties and stroke as examples, and it is the medical certificate that decides rather than the label.

David’s mother in law is becoming increasingly confused:
“Visiting angels have been a massive help in the care for my mother in law, who is getting increasingly confused. They provide companionship and support every day proving to be very reliable and consistent. They are there at times we can’t be, due to all the commitments of work and grand children.”
