Council Tax Exemption When Someone With Dementia Moves to a Care Home

Dementia Does Not Create an Automatic Exemption

A diagnosis of dementia, Alzheimer's disease, or any other cognitive condition does not by itself trigger a council tax exemption. What triggers the exemption is the move — specifically, a permanent move into a care home, nursing home, or hospital. The diagnosis explains why the move happened, but the council tax rules care about the living arrangement, not the medical label.

This matters because families sometimes assume the dementia diagnosis alone entitles them to relief. It does not. The relief comes from what happens next.

Class E: The Empty Property Exemption

When a person with dementia moves permanently into a registered care home and their property is left unoccupied, the property qualifies for a Class E exemption under The Council Tax (Exempt Dwellings) Order 1992. Class E reduces the council tax on the empty property to zero.

The conditions are straightforward:

• The person's sole or main residence is now the care home
• The property they left is unoccupied
• They are still the owner or tenant

No medical certificate is required for Class E. No benefit test. The council needs evidence of the permanent care home placement — typically the admission agreement or a letter from the care home manager — not a dementia diagnosis.

When the SMI Disregard Also Applies

If a spouse or partner remains living in the property, Class E does not apply (the property is occupied). Instead, the person with dementia who has moved to the care home is disregarded under Schedule 1, Paragraph 7 — they no longer count as a resident.

But there is a second route that sometimes overlaps: the Severe Mental Impairment (SMI) disregard. If the remaining resident also has a severe mental impairment, they can be disregarded under Schedule 1, Paragraph 2 — provided they have both a medical certificate from a registered practitioner and entitlement to a qualifying benefit (Attendance Allowance, PIP daily living, DLA care mid/highest, ESA, UC with LCWRA, or several others).

When both residents are disregarded — one as a care home resident, one as severely mentally impaired — the property qualifies for a 50% discount. If only the care home resident is disregarded and the remaining spouse is the sole non-disregarded adult, the 25% Single Person Discount applies.

The care home route and the SMI route are legally independent. You do not need an SMI certificate to claim Class E, and you do not need a care home placement to claim the SMI disregard.

The Transition Period

Many dementia care moves start with a hospital admission — perhaps after a fall or a crisis — followed by weeks of assessment, then a care home placement. During the initial hospital stay, the property may still be treated as the person's main home if the admission is temporary.

The Class E start date is the date permanent residence shifted. If hospital records show that a return home was ruled out early in the admission, the exemption can be backdated to that point rather than the later care home move-in date. This is worth pursuing because the gap between hospital admission and care home placement can be months.

Acting on Someone's Behalf

When a person with dementia lacks capacity to manage their own council tax, someone else needs legal authority to act. The correct route is a Property and Financial Affairs Lasting Power of Attorney (LPA) registered with the Office of the Public Guardian, or a Court of Protection Deputyship order. A Health and Welfare LPA does not cover financial matters. A DWP appointeeship covers benefits but not council tax accounts.

Without formal authority, councils will not release refunds, change account details, or process appeals on behalf of the person in care.
