How to split bills in a student house
Five people, one name on the electricity account, and a term that empties the house for six weeks. The arithmetic is easy; the exposure is not.
In this guide
Split student house bills equally per person, not per room, and put a different housemate’s name on each account. Rent may vary by room size, but electricity, gas, water, broadband and insurance are used by everyone and are not worth metering. The part that matters is liability: whoever’s name is on an account owes the full amount if the house does not pay, so spread the accounts across the group and pay every bill from a shared record that shows who has contributed each month.
- Divide shared bills equally per person. Room size is a rent question, not a broadband question.
- Never let one person hold every account. That housemate is personally liable for the whole house.
- Agree the payment date before the first bill, not after the first late one.
- Term breaks do not pause standing charges. Decide in September what happens over the winter break.
- Write the arrangement down while everyone is still enthusiastic — week one, not week nine.
A student house is the hardest version of shared bills and the one people are least prepared for. The group is usually new to each other, the incomes are irregular, the tenancy is short, and one person ends up with their name on an account for a service that four other people use. Nothing about the maths is difficult. Everything about the exposure is.
Which bills split which way
| Bill | How to split it | Why |
|---|---|---|
| Rent | By room, if rooms differ | The one bill where the thing being paid for genuinely differs per person. See splitting rent with unequal bedrooms. |
| Electricity and gas | Equally | Sub-metering a shared house is impossible and attempting it poisons the group. Heating is a house-level decision anyway. |
| Water | Equally | Often a fixed charge, and usage tracks headcount closely enough that measuring it is not worth the friction. |
| Broadband | Equally | A flat-rate service everyone uses. The person who streams more does not cost the house more. |
| Contents insurance | Equally, or per person by cover | Equal is fine unless one housemate insures substantially more expensive belongings and the premium reflects it. |
| Shared streaming and subscriptions | Equally among those using it | Opt-in only. A subscription one person chose is that person’s bill until somebody else asks to join. |
| Cleaning supplies and consumables | Equally, from a small kitty | Too small to itemise. A fixed monthly contribution beats twelve receipts for toilet roll. |
| Anything one person chose alone | That person pays | A gym add-on, a games subscription, a delivery pass. Individual choices stay individual. |
These are defaults, not rules. The value of writing them down in week one is that nobody has to argue from first principles in week nine.
Five people, $350.00 of shared bills, $70.00 each. That is the whole calculation, and it takes ten seconds. What takes the rest of the year is making sure five separate people actually transfer $70.00 on the same date every month — which is a record-keeping problem, not a maths problem.
Whose name goes on the account
This is the part that catches people out. An energy or broadband account has one named holder, and that person is legally on the hook for the full balance regardless of what the house agreed between themselves. If the house underpays, the supplier chases the name on the account, and a missed payment can land on that person’s credit file rather than on the group’s.
- Spread the accounts. One housemate takes energy, another broadband, another water, another insurance. Nobody carries the whole house.
- Ask the supplier about joint accounts. Some energy and broadband providers allow several named tenants, which spreads liability properly. It costs nothing to ask.
- The account holder is not the house bank. They pay the supplier, and the house reimburses them — but that reimbursement has to be logged, or the account holder is quietly funding the house.
- Take a meter reading on the day you move in and the day you leave. Photograph both. This is the single cheapest piece of protection against an estimated final bill.
- Keep every bill in one shared place. Not one person’s inbox. When a bill is disputed nine months later, whoever can produce the PDF wins the conversation.
In a student house, the person with their name on the electricity is not the treasurer. They are the guarantor.
Setting it up in the first week
- List every bill the house will actually receive. Energy, water, broadband, insurance, licence fees, and any subscription the house intends to share. Include the ones that only arrive quarterly — those are the ones that surprise people.
- Assign one named account holder per bill. Write down who holds what. Aim for an even spread rather than the most organised housemate taking all of them, which is what happens by default and is the worst outcome.
- Agree a single payment date. Pick a date two or three days after the bulk of student finance or wages land. Chasing five people on five different dates is what makes housemates stop asking.
- Put every bill into one shared expense record. Each bill logged with the amount, the date and who paid it. The point is not accounting — it is that nobody has to remember, and no one’s contribution is invisible.
- Set the recurring ones once. Rent, broadband and insurance are the same amount between the same people every month. Enter them as recurring and stop re-entering them.
- Decide the term-break rule now. Standing charges, broadband and insurance continue whether the house is occupied or not. Agree in September that they are still split equally over the winter and spring breaks, and there is no argument in December.
- Write it into a one-page house agreement. Bills, split method, payment date, account holders, and what happens if someone leaves. One page, everyone has a copy.
The situations that actually cause arguments
- Someone goes home for six weeks and wants a discount. Fixed costs — standing charges, broadband, insurance — stay split equally, because the house pays them whether or not that room is occupied. Variable usage in a house of five barely moves. Agree this in advance and it is a non-issue.
- A housemate drops out or moves home permanently. Their liability usually runs to the end of the tenancy unless the landlord agrees a replacement. Split the bills between the people actually in the house from the handover date, and keep the tenancy question separate from the bills question.
- One person consistently pays late. This is the most common failure and it is rarely malice. A shared record that shows who has paid removes the need to accuse anyone — see what to do when a roommate will not pay their share.
- The house is on all-inclusive rent. Check what "inclusive" covers and whether there is a usage cap. Many inclusive tenancies bill the excess back to the house in one lump at the end of the year, and nobody has budgeted for it.
- A guarantor gets involved. Guarantors are usually attached to rent, not utilities. Do not assume a parent’s guarantee covers an energy bill in a housemate’s name.
- Food. Keep it out of the bills pot entirely unless the house genuinely cooks together — see how to split groceries with roommates.
The rest of the mechanics are the same as any shared house: how to split utilities and shared bills covers the metering questions in more depth, and what to put in a roommate agreement is the one-page document version of everything above. If your rooms differ significantly in size, settle the rent split first using splitting rent with unequal bedrooms — bills are much easier to agree once rent is not still open.
