Council tax single person discount: who gets 25% off

A quarter off the bill if only one adult counts — and you do not have to live alone to qualify. Here is who is disregarded, the 50% discount almost nobody claims, and how to apply, because no council will apply it for you.

What is the single person discount?

A council tax bill assumes two adults live in the home. If only one adult counts, the bill is reduced by 25%. You will not get it unless you ask: GOV.UK is clear that you have to apply for a discount even when you plainly qualify, and councils do not apply it on their own.

Do I have to live alone?

No, and this is the part that costs people money. What matters is how many adults count, not how many live there. Some people are “disregarded”, meaning they are not counted at all. If everyone else in the home is disregarded, you are treated as the only adult and get the 25%.

A working adult sharing with a full-time student is the common case. Two adults, one bill, and a quarter off it that is very often never claimed.

Who is disregarded?

GOV.UK lists people under 18, those on certain apprentice schemes, 18 and 19 year olds in full-time education, full-time students, under-25s funded by the Education and Skills Funding Agency, student nurses, foreign language assistants registered with the British Council, people who are severely mentally impaired, live-in carers and diplomats.

Anyone under 18.
Full-time students, and 18 or 19 year olds in full-time education.
People on certain apprentice schemes, and under-25s funded by the Education and Skills Funding Agency.
Student nurses, and foreign language assistants registered with the British Council.
People who are severely mentally impaired, where the conditions are met.
Live-in carers, subject to the rules about who they care for.
Diplomats.

Each category has conditions, and the council will usually want evidence: a student certificate, a letter from an employer, medical certification or benefit details.

What if everyone in the house is disregarded?

Then the discount is 50%, not 25%. This is the one people miss, because the phrase everybody knows is the single person discount. If nobody living in the home counts as an adult for council tax, GOV.UK says you get 50% off the bill.

A separate rule covers a home occupied entirely by full-time students, which is normally exempt from council tax rather than discounted. Worth claiming rather than assuming.

How does it work in practice?

The test is always the same: count the adults who are not disregarded, and if the answer is one, you get 25% off.

One adult living alone: 25% off.
One working adult and one full-time student: The student is disregarded, so one adult counts: 25% off.
One adult and children under 18: Children are disregarded, so one adult counts: 25% off.
Two working adults sharing: No discount, even if only one of them pays the whole bill.
Everyone in the home disregarded: 50% off, or exempt entirely if they are all full-time students.

How do I apply?

Through your council, or through GOV.UK’s council tax discount service, which points you at the right one. Ask at the same time whether it can be backdated to when you actually became eligible, because it often can, and nobody will offer.

Your council tax account number and the property address.
The date your circumstances changed, not the date you noticed.
Who else lives there, and why each of them is disregarded.
Evidence for each disregarded person, such as a student certificate.
A question about backdating, in writing, so the answer is on record.

Find your council, if you would rather go to them directly.

What if someone moves in or out?

Tell the council promptly, both ways. A discount you are no longer entitled to has to be repaid, and there can be a penalty on top. If a partner stays over often, what matters is where they normally live rather than a count of nights, and the council is the right place to settle an unclear case.

Does it depend on what I earn?

No. The single person discount is about how many adults count, not about income. Council Tax Reduction is the separate, means-tested help for people on a low income, and you can be entitled to both at once. They are different applications.

Does this apply if I rent?

Yes. Tenants usually pay council tax directly, so the discount is usually yours to claim. In some shared houses the landlord is liable instead, and some tenancies include council tax in the rent, so check which applies to you before you budget for it.

Who pays council tax when renting covers each arrangement, and the band checker gives the actual charge for a property rather than an estimate.

Budgeting for a move? What household bills come to puts council tax alongside the energy, water and broadband.

Check the band before you agree the rent

The discount is a percentage of a bill that depends entirely on the band, and the gap between bands is wider than most people expect. Complete RenterCheck works out the council tax for the actual home from its band, alongside the energy, water and broadband.

Check the property

Run a free check on the property before you commit.

Council tax is usually the second biggest bill after the rent. The report works it out from the property's own band. The free check covers the energy rating, flood zone, crime nearby, conservation area and listed building status, and the sale history. Complete RenterCheck adds the rent comparison, the monthly running costs, licensing, and whether a company or a private individual owns it, and checks your tenancy agreement against the records.
