Council tax is usually the second-biggest fixed bill after rent or a mortgage, and it rises every April almost automatically. What doesn't happen automatically is the reduction thousands of households are entitled to but never claim — because unlike a pay rise, nobody tells you when you qualify. If you've never actively checked, there's a real chance you're owed money off your bill right now.
If you're the only adult (18 or over) living in your home as your main residence, you're entitled to a 25% discount on your council tax bill. It doesn't matter whether you own or rent, and it applies regardless of income.
Some people living with you don't count towards the adult total — they're "disregarded" for council tax purposes. Common examples include:
If everyone else in the household falls into a disregarded category, you may still qualify for the 25% discount even though more than one adult technically lives there — and if everybody in the property is disregarded, the bill can drop by 50%.
Councils don't proactively check your circumstances. If you became the only adult in your home — a partner moved out, a child left for university — the discount only starts from when you tell them, not from when it happened. Apply the same week your circumstances change.
Separate from the single person discount, every council in England, Scotland and Wales runs a Council Tax Reduction (sometimes called Council Tax Support) scheme for people on a low income, whether working or not. Depending on your council's scheme, your income, savings and who lives with you, this can reduce your bill by anywhere from a small percentage up to 100%.
You can apply whether you rent or own, and whether you're employed, self-employed, unemployed or retired. Pensioners are assessed under a more generous national scheme than working-age claimants in most areas.
Just as important as claiming what you're owed: tell your council promptly if your circumstances change the other way — someone moves in, a disregarded person stops being a student, and so on. Councils do run checks, and an overpaid discount usually has to be repaid, sometimes with the underpayment backdated to when the change happened. Keep your account updated in both directions and it stays simple.
