Disabled Band Reduction Band A: How the Council Tax Discount Works

Band A Properties Weren't Always Eligible

When the disabled band reduction scheme launched in 1993, Band A households were locked out. The scheme worked by dropping the charge to the band below — but Band A was already the lowest band, so there was nowhere to drop to.

The government fixed this in 2000. The Council Tax (Reductions for Disabilities) (Amendment) Regulations 1999 (SI 1999/1004) introduced a special formula for Band A: instead of paying the standard six-ninths of the Band D charge, qualifying Band A properties pay five-ninths.

How the Calculation Works

Every council tax band is expressed as a fraction of the Band D charge:

• Standard Band A = 6/9 of Band D
• Band A with disabled reduction = 5/9 of Band D

The difference — one-ninth of Band D — is your annual saving. That works out to roughly a 17% discount on the standard Band A charge.

Using Birmingham's 2026/27 Band D charge of £2,353.17:

• Standard Band A: £1,568.78 (6/9 × £2,353.17)
• Disabled reduction Band A: £1,307.32 (5/9 × £2,353.17)
• Annual saving: £261.46

The exact figures depend on your council's Band D rate, which varies. But the structure is the same everywhere in England.

The Same Eligibility Rules Apply

Band A properties must meet the same three conditions as any other band:

1. A substantially and permanently disabled person lives there as their main home
2. The property has at least one qualifying feature — an extra bathroom or kitchen, a room used mainly for the disabled person's needs, or indoor wheelchair floor space
3. The feature is essential or of major importance to the person's wellbeing

There's no relaxed test for Band A. The property still needs a qualifying physical feature.

Stacking With Other Discounts

The Band A disabled reduction is applied first. If you also qualify for a 25% single person discount, that's calculated on the already-reduced figure of £1,307.32 (in the Birmingham example), not the original Band A charge. Council tax support is applied after that.

Backdating for Band A

If the qualifying feature has existed for several years — a second bathroom installed in 2020, for example, or indoor wheelchair use since 2023 — the council should backdate the reduction to the earliest date when all qualifying conditions were met. There's no statutory time limit on backdating.

For a Band A property, each backdated year is worth roughly £260, depending on the council's historic Band D rates. Three years of backdating could mean a refund of around £780.

Claiming

Apply to your local billing authority in the usual way. Our Disabled Band Reduction Claim Guide covers the application process and includes tools for documenting the qualifying feature and building a backdating evidence trail.
