Split bills fairly with housemates
Short answer
Add up the house's bills, divide by housemates, then automate who pays what. At typical usage a shared house spends about £224 a month on energy, water and broadband, which is £74.67 each for three housemates, or about £17 per person per week. That is under the £19 to £29 per person per week Reading Students' Union found nine packages charging in March 2025. Heavy usage changes the answer: on Reading's high-usage £280 a month, three sharers pay £21.54 each a week and the cheapest package wins. Check your own house below.

A typical shared house pays about £224 a month for energy, water and broadband — £74.67 each for three housemates on an equal split. Your own house may land well above or below that. Equal is not always fair either, so most shared houses do better with a hybrid: room value for rent, liable adults for fixed household costs, and usage weighting for variable utilities.

Setting up energy at a new address?
The cap limits unit rates and standing charges, not your total bill, so what you pay still depends on what you use. It rises about 4% on 1 October. If you move in before then you start on today's rates and they reset underneath you, usually before your first bill arrives. For a typical dual-fuel home paying by direct debit that is £1,935 a year from October against £1,862 now, or £1,723 against £1,663 on Ofgem's own consumption basis.
Three ways to split a fair share
Use whichever rule fits the bill — most shared houses mix all three.
- Equal split: total divided by headcount. Fair when rooms and usage are similar — on a typical house's £224 split 3 ways, that's £74.67 each.
- By room: weight rent for room size, en-suite, or other differences, but keep flat-rate bills like council tax equal per adult.
- By usage: weight variable bills (energy, water) when one housemate is home all day. On the £224 example, a 1.2 weight lifts one share to £84.00 a month, the other two to £70.00 each — still £224 total.
- Mix and match: most houses use rent-by-room, fixed-costs-by-adult, and usage-by-weight together rather than one rule for everything.
What to do when a housemate won't pay
Most disputes come from unclear rules, not missing money. Have a plan before it happens.
- Check the written agreement first — it should already state payment dates and what happens if someone misses one.
- Send a clear reminder with the exact amount and the account it needs to reach, in writing.
- If it continues, whoever's name is on the account still owes the supplier — chase reimbursement in parallel, don't let the bill lapse.
- Persistent non-payment is a house-rules issue, not just a money one — involve your landlord or agent if it affects the tenancy.
Bills-included instead?
Some student lets bundle rent and bills into one fixed monthly price. That usually cuts the admin of chasing individual bills, but the fixed price often runs higher than a well-managed even split. Reading Students' Union research in March 2025 priced nine unlimited-bills providers at £335.75 to £496.43 a month for one four-bedroom, four-occupant house — about £19 to £29 per person per week. Whether splitting beats that depends on how much your house actually uses, and on how many of you there are.
- At typical usage (£224 a month): £17.23 per person per week with three sharing, £12.92 with four. Both come in under the £19.37 cheapest package in that research.
- At high usage (£280 a month — the same research's own figure for a high-usage house on direct supply) with four sharing: £16.15 each, still cheaper than any package in the range.
- At high usage with only three sharing: £21.54 each — more than the £19.37 cheapest package. That is the case where a bills-included package is genuinely the cheaper option.
- So £17 and £13 are what a typical house pays, not what yours will pay. Put your house's real monthly total into the calculator above before you sign a bills-included contract.
Council tax and the TV Licence sit outside the comparison
The £224 above covers energy, water and broadband — the three services bills-included packages actually price. Two more household costs usually land on top, and they are the reason a package quote and your own bill total are not comparing the same thing.
- Council tax: England's average Band D bill is £2,392 a year for 2026/27, per GOV.UK's Council Tax levels statistics for 2026 to 2027. The default is ten instalments, so about £239 a month, not £199 over twelve. It is a per-property charge, so it is normally split equally between the liable adults rather than weighted by room or usage.
- TV Licence: £180 a year from 1 April 2026, about £15 a month, and needed if anyone in the house watches or records live TV or uses BBC iPlayer.
- Full-time students are exempt from council tax. GOV.UK says a household where everyone is a qualifying full-time student does not have to pay it — but you usually still have to apply for the exemption rather than ignore a bill. Mixed student and non-student households may get a discount instead of full exemption.
- Only One Utility Bill, among the packages we checked, can include council tax at all, and then only as an optional extra — so compare packages on energy, water and broadband, then add these separately.
How Taupia automates the split
- Track uneven shares automatically on the rule your household sets, so nobody maintains a spreadsheet.
- See who's paid and who hasn't for each bill, in one shared view.
- Get renewal and contract-end alerts before a bad tariff auto-renews on the whole house.
- Everyone sees the same numbers, so the agreement stays a plan, not an argument.
| Bill type | Fair default split |
|---|---|
| Rent | By room value, adjusted for en-suite, size, or notable room benefits. |
| Council tax | By liable adults unless your tenancy setup changes legal responsibility. |
| Energy standing charges | Usually equal per liable adult. |
| Energy or water usage | By usage weighting when one person materially uses more. |
| Broadband base package | Usually equal; personal speed upgrades can be paid by the requester. |
| Personal add-ons | Paid by the person who requested the add-on. |
Fair split questions
What is the fairest way to split utility bills in a shared house?
Use a different rule for each bill type: rent by room value, fixed costs like council tax by liable adult, and variable utilities by usage when one person's usage is clearly higher. Equal split works fine when rooms and usage are already similar — agree the rule in writing before the first payment.
Should bills be split equally if bedrooms are different sizes?
Not usually for rent — weight it by room size, en-suite, or other clear differences. Bills that don't depend on room size, like council tax or a broadband base package, are typically still fine split equally per adult.
How do students usually split bills in a shared house?
Most student houses start with an equal split of the total, since usage differences are often small early in tenancy. Some houses then move to a hybrid — usage-weighted energy, equal fixed costs — once real bills show who is using more.
Is a bills-included package easier than splitting?
It's usually less admin, since one fixed price replaces multiple accounts and a monthly split. It's not always cheaper than a well-run even split, though, so it's worth comparing the actual numbers — see Taupia's student bill packages versus splitting comparison.
What happens if one housemate doesn't pay their share?
Whoever's name is on the account still legally owes the supplier, regardless of the house agreement. Send a clear reminder first, then treat repeated non-payment as a house-rules problem — loop in your landlord or agent if it starts affecting the tenancy.
How do we recalculate the split when a housemate leaves mid-month?
Take a meter reading on the day they go, then pro-rata the fixed costs by the days they were resident and settle usage against that reading. Liability to the supplier follows whose name is on the account; liability to the landlord follows the tenancy — neither is arithmetic. Taupia's bill splitting Q&A covers both.
What do we do when a bill lands higher than the monthly estimate?
Split the shortfall by the same rule you split the bill itself, rather than charging it to whoever happens to hold the account. Re-run the per-person figures on the calculator above with the actual amount, then adjust next month's standing order so the gap does not repeat.
What if one housemate's usage changes partway through the tenancy?
Only the variable portion needs redoing: leave rent, broadband and council tax shares alone and reweight the energy share from the date the change started. Agree the new weighting before the next bill — Taupia's bill splitting Q&A sets out what houses usually consider fair.
How often should we redo the split?
Once a term is usually enough, plus any time someone moves in or out, a tariff renews, or a fixed deal ends and the unit rate moves. Recalculating monthly invites arguments; never recalculating means the numbers quietly stop matching the bills. There is more in Taupia's bill splitting Q&A.
