Who counts as a full-time student
Every rule on this page hangs off the phrase 'full-time student', and it has a statutory definition, not a common-sense one. GOV.UK's test is a course that lasts at least 1 year and involves at least 21 hours of study per week (Source: GOV.UK). If you are under 20 and studying for a qualification up to A level, the thresholds drop to a course of at least 3 months with at least 12 hours of study a week (Source: GOV.UK).
Lancaster City Council words its own test slightly differently: enrolled on a full-time course, aged 18 or over, at a UK or EU college or university, on a course running at least 24 weeks in the year with at least 21 hours of study per week — and distance learners qualify if they meet the 24-week and 21-hour tests (Source: Lancaster City Council). The phrasings are two limbs of the same definition; we give you both because the council's version is the one its assessors actually work from.
Two situations sit outside anything either source publishes: placement years on a sandwich course, and PhD students in the writing-up stage. Neither GOV.UK nor Lancaster City Council states a rule for them, so we are not going to invent one. The right move is to ask your university's student advice service and the council before assuming an outcome in either direction.

How the exemption actually works in Lancaster
Lancaster City Council's student-tenancies page opens with the point most houses miss: "When the student signs a tenancy agreement, they will be liable for Council Tax from the start date of that agreement." (Source: Lancaster City Council). Not from freshers' week, and not from the day you carry boxes in — from the date on the agreement, which is often weeks before teaching starts.
The exemption then applies provided the occupants are full-time students and — the clause doing the work — the council is in receipt of proof of studies, after which it is applied to the account for the duration of the full-time course (Source: Lancaster City Council). Proof means your university registration certificate, submitted with the council's student council tax discount form, which is linked from the council's own pages (Source: Lancaster City Council). One certificate per student is the safe assumption, and the space between the tenancy start date and the day the council receives that evidence is exactly where surprise bills breed.
Whose name the bill sits in depends on how the house signed. Where each occupier signed a separate agreement for their own room, the property counts as a house in multiple occupation for council tax and the owner is liable; where everyone signed one joint agreement, the occupiers are jointly and severally liable — any one name can be pursued for the whole charge (Source: Lancaster City Council). The exemption question is identical either way; what changes is who the council writes to.

One housemate isn't a student: the arithmetic
One non-student changes the category, not just the amount. The household gets a council tax bill, though it may still qualify for a discount (Source: GOV.UK). The discount logic runs on 'disregarded' people: 25% off if everyone except one person in the home is disregarded, 50% off if everyone is (Source: GOV.UK). Full-time students are disregarded — so five students plus one full-time worker means a bill with 25% off it.
The discount does not scale down gently. Add a second non-disregarded adult and neither rule is met: the discount goes and the full charge stands. Before anyone concludes they have cost the house its discount, check the full disregarded list — student nurses, under-18s, 18-to-19-year-olds in full-time education, certain apprentices, under-25s with Education and Skills Funding Agency funding and British Council-registered foreign language assistants all count (Source: GOV.UK).
Lancaster City Council says the same thing locally: an all-student property is exempt, while a household mixing full-time students with part-time students or non-students is not, though a reduction may apply — the council's own worked example is the 25% discount (Source: Lancaster City Council). Note the part-time detail: for council tax, a part-time student sits on the non-student side of the line, however unfair that feels at 20 hours a week.

When your course ends, the clock restarts
The exemption lasts the duration of the full-time course, and Lancaster City Council is precise about what follows. If your course ends while the tenancy is still running and the house is left unoccupied but furnished, a 100% charge is payable from the end of the course to the end of the tenancy agreement (Source: Lancaster City Council). This is the rule that catches finalists: exams finish, everyone goes home, and the empty summer weeks left on the agreement become taxable ones.
Stay on and it depends who remains: a sole occupier whose course has ended gets a 25% single occupancy discount and pays 75% of the bill, while several occupants remaining after courses end pay a 100% charge (Source: Lancaster City Council). Graduating and staying in Lancaster is a fine plan — just budget the council tax from your course end date, not your tenancy end date.
It is also worth showing this section to whoever stands guarantor on the tenancy, since it is the one scenario where a student house generates a genuinely payable bill. What a guarantee covers — and what we ask guarantors for — lives on our parents-and-guarantors page.

Why 'council tax included' is the wrong question
Every autumn, houses get compared on which bills are 'included', and council tax drifts onto the list as if it were another utility. It is not. For an eligible all-student household there is nothing to include: the exemption belongs to the household, the household applies for it, and the household supplies the evidence. A statutory exemption cannot be bundled into anyone's rent — a listing that implies otherwise is selling you your own legal position as a feature.
What bills-included genuinely covers, with us, is gas, electricity, water and broadband — costs a landlord can actually contract for and take on. Council tax is deliberately not on that list: in an all-student house there should be nothing to pay, and where there is something to pay, the amount is set by the council's rules above, not by a tenancy. The part that does come from us is the written tenancy start date — the date your liability runs from — which is the one document in the evidence trail your university cannot give you.

If a bill arrives anyway
A bill is not a verdict — it is usually the council telling you it holds no proof of studies yet. GOV.UK is explicit: "You need to apply for a Council Tax discount or an exemption, even if you're disregarded." (Source: GOV.UK). An eligible house that never applies keeps getting billed, and an unanswered bill does not cancel itself.
The fix is the process from earlier on this page: registration certificates in, student form in, exemption applied from there for the duration of the course (Source: Lancaster City Council). If the bill still looks wrong afterwards — wrong names, wrong dates, a mixed-household sum you do not recognise — Lancaster City Council's council tax team is on 01524 582900, with an online contact form on its website (Source: Lancaster City Council). GOV.UK's apply page routes any address to the right council by postcode; for a Lancaster house it lands you on the pages linked above (Source: GOV.UK).
