Disabled Child Council Tax Reduction: How to Claim a Band Reduction

Children Qualify Too

The disabled band reduction is not limited to adults. If a substantially and permanently disabled child lives in the home as their main residence and the property has a qualifying physical feature because of the child's needs, the parent or guardian who pays the council tax can claim the reduction. The bill drops by one band — Band D charged at Band C, for example — and Band A properties get roughly a one-sixth reduction.

Under the Council Tax (Reductions for Disabilities) Regulations 1992, the qualifying individual does not need to be the liable taxpayer. They just need to live in the dwelling. A child of any age who meets the disability test satisfies this requirement.

What Counts as a Qualifying Feature

The home must have at least one of three physical features that exists because of the child's disability:

An additional bathroom or kitchen. If you installed a second bathroom — a downstairs wet room, an adapted shower room — because your child cannot safely use the main bathroom, this qualifies. The key: it must be an extra bathroom, not the only one.

A room used predominantly for the child's needs. A sensory room equipped for a child with autism, a physiotherapy or treatment room with fixed equipment, a dedicated medical equipment room for a child on home ventilation, or a ground-floor bedroom converted because the child cannot manage stairs. The room must be predominantly used by and for the child — a dual-purpose family room that happens to contain some therapy equipment is harder to demonstrate.

Indoor wheelchair floor space. If your child needs to use a wheelchair indoors and the home has sufficient floor space for them to use it, this qualifies. Widened doorways or clear turning areas may contribute to that space, but they do not qualify on their own. The child must use the wheelchair inside the home, not just outdoors.

Evidence for a Child's Claim

The evidence package looks similar to an adult claim, with a few differences.

Medical evidence. A paediatrician's letter, a child development centre report, or a DLA/PIP award notice confirming the child's condition is substantial and permanent. You do not need a specific benefit to qualify — the reduction is entirely independent of DLA or PIP entitlement — but award letters are convenient proof of disability that councils readily accept.

OT or therapy assessment. If social services or a private occupational therapist assessed your home and recommended adaptations, that report is powerful evidence. It connects the physical feature directly to the child's clinical needs, which is what the council needs to see.

Photographs and floor plans. Show the qualifying feature in its daily state — the sensory room with equipment set up, the downstairs wet room, the wheelchair turning space. Councils and visiting officers need to see that the feature is genuinely in use, not theoretical.

Disabled Facilities Grant paperwork. If your local authority funded the adaptation through a DFG, the grant application and approval documents are strong supporting evidence. They show the council itself already accepted that the adaptation was necessary for a disabled child.

Parental Responsibility and Who Applies

The person liable for the council tax submits the application. For most families with a disabled child, that is one or both parents. Parental Responsibility under the Children Act 1989 gives parents the legal standing to act on behalf of a child under 18 — no additional authorisation is needed.

If the child turns 18 and remains living in the home, the parent can still apply as the liable taxpayer. However, if the council needs to discuss the adult child's medical details, they may require a signed Letter of Authority or, if the young person lacks mental capacity, a Lasting Power of Attorney or Court of Protection order.

How It Interacts With Other Reductions

The disabled band reduction is calculated first. Any other discounts or reductions are then applied to the already-reduced figure:

• Single parent discount (25%): If the disabled child is the only other person in the home, you get the band reduction first, then 25% off the reduced figure. Children under 18 are automatically disregarded for council tax headcount purposes.
• Council Tax Support: Means-tested support is calculated on the bill after the band reduction and any discounts. Getting the band reduction lowers your CTS starting figure.
• Carer disregard: If a qualifying carer also lives in the home, they may be disregarded too, potentially triggering the single person discount on top of the band reduction.

Backdating for Children

Many families live with qualifying adaptations for years before learning about the scheme. The reduction can be backdated with no statutory time limit, as long as you can show that the feature and the disabled child were both present during the historic periods. If a wet room was installed three years ago, you can claim back three years of overpaid council tax.

Gather the installation date (invoices, building control certificates, DFG approval letters) and evidence that the child was living in the home during those years (child benefit letters, school correspondence, medical records). The council recalculates each affected financial year and either credits the account or issues a refund.
