Council Tax Appeal for an Elderly Parent or Family Member

When your parent has dementia and is overpaying council tax, or they've been refused an exemption they're clearly entitled to, they're not going to navigate the appeal system themselves. That's where you come in — and the Valuation Tribunal allows it, provided you handle the authorisation properly.

Can You Appeal on Someone Else's Behalf?

Yes. The VTE allows representatives to act on behalf of appellants. You can serve the Section 16 grievance, submit the appeal, prepare the evidence, and present the case at the hearing. The appellant doesn't need to attend.

This is especially important for cases involving severe mental impairment (SMI) exemptions, disabled band reductions, or care home–related disputes, where the person affected may lack the capacity to manage the process themselves.

Getting the Authorisation Right

The council and the VTE need to see that you have authority to act. Three routes:

Lasting Power of Attorney (LPA) for Property and Financial Affairs. If you hold an LPA registered with the Office of the Public Guardian, send a certified copy with your first correspondence. Check with the council what documentation it needs to recognise you as a representative.

Written authorisation from the taxpayer. If your parent has mental capacity but finds the process overwhelming, a signed letter from them authorising you to act on their behalf is sufficient. It should name you, state the property address, and confirm you're authorised to correspond with the council and the VTE about their council tax.

Court of Protection Deputyship. For family members who lack capacity and where no LPA exists, a deputyship order grants the authority set out in the order — but this is a longer and more expensive route. If the council tax dispute is the only issue, a signed letter (if they still have capacity for that) is simpler.

Without clear authorisation, the council can refuse to discuss the account with you, citing data protection. Get this in place first — before you serve the grievance.

Running the Process for Them

Once authorised, you handle every step:

Checking entitlements. Many elderly householders are unknowingly missing discounts or exemptions they qualify for — SMI exemptions (if a registered medical practitioner certifies they meet the SMI test and they meet the qualifying-benefit conditions), single person discounts (if they live alone after a spouse enters care or dies), disabled band reductions (if the property has qualifying adaptations), or care home exemptions (if their former sole or main home is left unoccupied after a permanent move into residential care).

Serving the Section 16 grievance. Write and send the statutory grievance letter in your parent's name, with your details as authorised representative. Include the LPA or written authorisation as an enclosure.

Gathering evidence. For SMI exemptions, you'll need a completed SMI certificate from their GP plus proof of a qualifying benefit. For disabled band reductions, the council may request an occupational therapy assessment or details of adaptations. For care home disputes, the care home contract and admission date are key evidence.

Preparing the evidence bundle. Organise the documents under the VTE's STEP framework — the panel reads the bundle before the hearing, so a clear, numbered bundle with a contents page makes their job easier.

Representing at the Hearing

You can present the case at the tribunal hearing in your parent's name. The panel is accustomed to family representatives — this is common in cases involving elderly or vulnerable appellants.

If appearing by video (the default format), set up from a quiet location with the evidence bundle accessible on screen or printed beside you. The panel will address questions to you as representative, and you present the case as if you were the appellant — referencing the evidence, explaining the grounds, answering the panel's questions.

Your parent does not have to attend if you represent them. Tell the VTE in writing before the hearing who will represent them; if nobody will attend, ask the VTE in advance whether it can hear the case in their absence.

Common Scenarios

Parent in care home, property empty and charged a premium. The property may qualify for a Class E exemption (left empty because the resident is in residential care) or an exception from the empty home premium. The council sometimes applies the premium automatically when a property becomes unoccupied, without checking whether an exemption applies.

Parent with dementia, still at home, no SMI exemption claimed. If they receive a qualifying benefit (Attendance Allowance, PIP daily living, DLA care, UC with LCWRA), they may be entitled to the SMI disregard or a full Class U exemption. Many families don't know this exists until they're already dealing with unaffordable bills.

Refused discount and the council won't engage. Councils sometimes refuse discounts based on outdated information or automated checks (like credit reference data suggesting another adult at the address). A Section 16 grievance forces a proper review, and a VTE appeal forces a decision if the council continues to stall.
