SMI Evidence Required for Council Tax in Scotland

The Three Pillars of an SMI Claim

Every SMI council tax disregard in Scotland rests on three statutory conditions that must all be satisfied on the same day. Your evidence package needs to prove each one.

1. Functional impairment — a severe impairment of intelligence and social functioning that appears to be permanent, certified by a registered medical practitioner.

2. Medical certification — a signed certificate from a GP or hospital consultant confirming the person is, or is likely to be, severely mentally impaired.

3. Qualifying benefit — current entitlement to a qualifying disability benefit (not necessarily active payment — entitlement alone is sufficient under Scottish law).

The council needs evidence for all three conditions before it can establish entitlement. Here's what to submit for each.

The GP Certificate

The council needs a signed statutory certificate from a registered medical practitioner. Most councils provide their own form with a section for the doctor to complete. Glasgow City Council has a dedicated Section 2 on their SMI application form; Edinburgh Council asks you to download and print a separate "Registered Medical Practitioner Authorisation" form.

What the certificate must state:

• The person's full name and address
• That the person has a severe impairment of intelligence and social functioning which appears to be permanent
• The certified start date — the date from which the impairment has been, or is likely to have been, present

The certified start date is critical for backdating. A GP who writes "currently severely mentally impaired" without specifying when it began limits your backdating to the certificate date. Push for the earliest date the doctor can certify — this is often years before the application.

GPs must complete this certificate free of charge under NHS General Medical Services contract obligations. If your surgery tries to charge, reference the statutory duty. You can also use a hospital consultant or any registered medical practitioner — it doesn't have to be the patient's own GP.

Benefit Entitlement Proof

You need an official benefit award notice from Social Security Scotland or the DWP showing:

• The specific benefit name (Adult Disability Payment, Pension Age Disability Payment, Attendance Allowance, etc.)
• The rate and component (e.g., enhanced rate daily living component)
• The entitlement start date

The start date on the benefit award is one of the three dates used to calculate how far back the disregard can be applied. Keep every award letter — even old ones from superseded benefits like DLA or PIP that have since been replaced by ADP or PADP.

If the benefit was suspended (for example, during a hospital stay longer than 28 days), Scottish law recognises that statutory entitlement continues during suspension. A suspension letter does not break the qualifying condition.

Legal Authority Documents

If a representative or carer applies on behalf of a resident who lacks capacity, the council may require proof of legal authority. Examples include a registered Continuing or Welfare Power of Attorney, or a Guardianship Order. Ask the council which document and copy format it accepts.

• Continuing Power of Attorney: provide proof that it is registered and grants the relevant financial powers; ask whether the council requires a certified copy or registration certificate
• Guardianship Order: provide the order showing the relevant financial powers

Additional Supporting Documents

Beyond the three core requirements, include:

• A completed local authority application form (each council has its own)
• Proof of residence at the property (utility bill, council tax bill)
• If claiming a disability band reduction alongside the SMI disregard, an occupational therapist report or photographs of the adaptations

Common Evidence Mistakes

Submitting a diagnosis letter instead of the SMI certificate. A consultant's letter confirming Alzheimer's disease is not the same as the statutory certificate confirming severe mental impairment. The council needs the specific SMI certification.

Providing a benefit statement without the start date. Online benefit statements sometimes show current rates without the original entitlement date. Request a full award notice from Social Security Scotland that includes the start date.

Not including historical benefit documents for backdating. If the qualifying benefit changed — say from DLA to ADP — you need both award notices to establish continuous entitlement.

Our Scotland SMI and Disability guide includes an evidence assembly log that walks you through gathering every document the council needs, along with a GP cover letter template that explains the certification requirement in terms the surgery can't misunderstand.
