Millions of households across Britain could be paying more council tax than they need to - simply because they do not realise they qualify for discounts or exemptions, say experts.

Disabled people, carers, students, pensioners and those living alone are among the groups who may be entitled to reductions worth hundreds - or even thousands - of pounds a year.

One of the biggest forms of support is the Disabled Band Reduction Scheme, which helps households where a property has been adapted for a disabled resident.

Families may qualify if the home has an extra bathroom, kitchen or room needed because of a disability, or extra indoor space for wheelchair use. If approved, the property is moved down to the next lowest council tax band. Homes already in Band A can receive a 17 per cent discount instead.

Separate discounts also exist for people considered “severely mentally impaired” for council tax purposes - which can include conditions such as dementia, Alzheimer’s disease and severe learning difficulties. In some cases, households can receive a 100 per cent exemption.

To qualify, people usually need medical certification from a GP or healthcare professional and must receive certain disability-related benefits.

But disability discounts are only part of the system.

Under council tax rules, some adults are treated as “disregarded”, meaning they are not counted when councils calculate how many adults live in a property. If only one counted adult remains, households can typically get a 25 per cent discount. If everyone in the property is disregarded, bills can sometimes be cut by 50 per cent - or removed entirely in certain cases.

Martin Lewis explains on his MoneySavingExpert website: "Missing out on a discount? If you're single, a single parent, a student, or have physical or mental disabilities, you may be.

"Up to 2.25m on low incomes not claiming Council Tax Support. Since 2024 (if not earlier) we've been warning about this on the back of Policy In Practice research, which revealed huge under-claiming, often by people on Universal Credit (UC) wrongly assuming it's automatic."

Full list of people who may qualify for Council Tax discounts or disregards

According to council and Government guidance, the following groups may qualify for reductions, exemptions or be treated as “disregarded” for council tax purposes:

  • People living alone
  • Disabled people needing adapted homes
  • People who are severely mentally impaired
  • Full-time students
  • Student nurses
  • Apprentices and youth trainees
  • 18 and 19-year-olds still in education
  • School and college leavers under certain rules
  • Live-in carers
  • Care workers on low pay
  • People living in care homes
  • Hospital patients
  • Prisoners and people in detention
  • Members of religious communities such as monks and nuns
  • Diplomats and certain international institution workers
  • Members of visiting armed forces
  • Some non-British dependants of students
  • People staying in hostels or night shelters
  • Homes where every resident is classed as disregarded
  • Some pensioners on low incomes through council tax support schemes

The full list is on the Gov.uk website.

Experts have repeatedly warned that many eligible households never apply because the rules can appear confusing or because people are unaware the discounts exist.

Applications are handled through local councils, and households usually need to provide evidence such as benefit letters, medical forms or proof of student status.

In some cases, discounts can also be backdated. Online forums are filled with people discovering they may have overpaid for years before learning they qualified for help.

How to check your Council Tax band

As well as millions of pounds of reductions and support, many people are in the wrong band and paying too much.

Households in England and Wales can check their band for free through the Government’s online council tax band checker.

Scottish residents can use the Scottish Assessors Association website.

Experts say one of the clearest signs something may be wrong is if similar homes nearby are in a lower band.

According to the Valuation Office Agency, “similar” usually means properties of the same size, type and age located on the same street, estate or nearby rural area.

If neighbours living in near-identical homes are paying less, this may support an appeal.

When you may be able to appeal your Council Tax band successfully

People may have grounds to challenge their band if:

  • Similar nearby homes are in a lower band
  • The property has been altered or divided into flats
  • Part of the home has been demolished
  • The band appears incorrect based on comparable properties

People who have owned or lived in a property for less than six months may have stronger rights to challenge the valuation.

A warning for anyone appealing their Council Tax band

But there is also a major warning: challenging your council tax band could actually backfire and leave you paying even more.

According to mortgage expert Mel Whiting from Norton Finance, some successful-looking appeals can trigger wider property reviews that push homes into higher bands instead.

“Appealing your council tax isn’t a free hit,” Whiting warned.

“If the council decides your home is undervalued your bill can go up substantially and it may even trigger reviews of neighbouring homes.

“One appeal can end up costing a whole street more. In some cases, a failed appeal can permanently move households into a higher council tax band.”
