Most people pay their council tax bill in full without ever checking whether they should be. Several of the reductions Hounslow Council offers are not applied automatically — you have to ask for them — and some are missed almost entirely.
Living alone — 25% off
If you are the only adult in the property you are entitled to a single person discount. It does not happen by itself. You have to apply.
Severe mental impairment
If someone in the household has a permanent severe impairment of intelligence and social functioning — dementia, Parkinson’s, the lasting effects of a stroke, a learning disability — they may not be counted for council tax at all. You need a certificate from a registered medical practitioner, usually a GP, and the person normally needs to be receiving one of a range of qualifying benefits such as Attendance Allowance, the care component of DLA or the daily living component of PIP.
Depending on who else lives in the property, that can mean the whole bill removed where everyone qualifies, 50% off where everyone else is also disregarded, or 25% off where one other adult is counted. It is not means-tested, so savings and income make no difference. Ask whether it can be backdated.
Carers — check again if you were told no
A live-in carer can be disregarded for council tax, which can take 25% off the bill. All of the following must apply: you provide at least 35 hours of care a week, you live in the same property as the person you care for, you are not their spouse or partner, and you are not their parent if they are under 18. The person you care for must also receive a qualifying benefit — Attendance Allowance, the daily living component of PIP, the care component of DLA at the middle or higher rate, or Constant Attendance Allowance. You do not need to be claiming Carer’s Allowance yourself.
There is a reason to check again if you were turned down before. A MoneySavingExpert investigation published in January 2026 found around one in five council websites in England and Wales were showing out-of-date qualifying rules for this discount, some dating from a 2013 rule change. MoneySavingExpert confirmed in May 2026 that all 69 councils it identified had since corrected their websites. If you looked into this previously and were told you did not qualify, it is worth asking again, and asking for it to be backdated to when you first became eligible.
Disability band reduction
If the home has been adapted for a disabled resident you may be charged at one band lower. Hounslow states that where the property is already in Band A, the bill is reduced by one ninth of the Band D charge instead. Qualifying adaptations include an extra room needed to meet the disabled person’s needs, an additional bathroom or kitchen, or enough space to use a wheelchair indoors. The disabled person can be an adult or a child and does not have to be the bill payer.
Students and others not counted as adults
A property where everyone is a full-time student is exempt, and a course generally counts if it runs at least 21 hours a week for at least 24 weeks a year. Full-time students, student nurses, apprentices, people with a severe mental impairment, qualifying live-in carers, some 18 and 19-year-olds still in education, and people in prison other than for non-payment are all disregarded when counting how many adults live in a property.
If you are on a low income
Hounslow runs its own Council Tax Support scheme, so the rules here are local rather than national. Working age households are assessed under a banding scheme, with the earnings thresholds increased by £10 for households with one child and £30 for households with two or more. Unearned income such as benefits, maintenance or payments from a trust is not counted. For pension age households the banding scheme does not apply and entitlement depends on household income, property band and savings, with a reduction applied where savings reach £6,000 and no entitlement at £16,000 or above.
If you are struggling to pay
Contact the council before you miss a payment rather than after. There are more options available while the account is still in order. You have a legal right to ask for the bill to be spread over 12 instalments instead of 10, and Hounslow operates a hardship fund for working age households facing exceptional hardship. Free independent debt advice is available from Citizens Advice.
One warning about challenging your band
You can ask the Valuation Office Agency to review your council tax band if you have become the taxpayer within the last six months, if there has been a material reduction such as an adaptation for a disabled person, or if you start or stop using part of your home for business. Be aware that a review can move a band up as well as down, and can affect neighbouring properties too. That is worth knowing before you start.
