Moving in together: how to split the bills fairly
Short answer
Most couples split bills 50/50 or by income, where each partner pays the same share of the bills as their share of combined take-home pay. YouGov found 48% of Britons think an income split fairest. Agree the rule before the first bill, spread the account names, and tell the council if either of you had the 25% single person discount.

council tax discount that ends when a partner moves in
Two people, one set of bills and often two different incomes. This guide sets out the two common ways couples split them, what YouGov found people think is fair, whose name should go on each account, and what changes for council tax, with a calculator for your own figures.
Split your bills by income or 50/50
It starts on £442.86 a month, the average couple's bills on Taupia's household bills page at October to December 2026 prices, with example take-home pays of £2,400 and £1,600 a month. Replace all three with your own, or switch to an even split.
Each person's share of the bills
- Person 1 pays 60%£265.72 a month
- Person 2 pays 40%£177.14 a month
Each share is that person's take-home pay as a share of everyone's combined take-home pay, applied to the total. Shares are rounded to the penny and add up to the total. Taupia's app splits each bill by the percentages your household sets.
Should couples split bills 50/50 or by income?
There is no rule, and couples are split on it. What matters is agreeing one before the first bill arrives.
- YouGov found 48% of Britons think bills should be based on how much each partner earns, and 37% think they should just be 50/50.
- Among 1,254 people in a relationship where both partners work and live together, 46% split bills 50/50 and 38% split them in proportion to their income.
- Where incomes are clearly different, 49% of those couples split proportionately, yet 33% still split 50/50.
- A 50/50 split is the simplest to run. An income split leaves both partners with the same share of their pay once the bills are paid.

How do you split bills by income?
Each partner pays the same share of the bills as their share of your combined take-home pay.
- Add your take-home pays together, divide each one by the total, and apply that percentage to the bills.
- Worked example (Taupia's arithmetic): take-home pays of £2,400 and £1,600 a month make £4,000, so 60% and 40%. On £442.86 a month, the average couple's bills on Taupia's household bills page, that is £265.72 and £177.14, which add up to £442.86.
- Split 50/50 instead, each would pay £221.43.
- Use take-home pay rather than salary, so tax and pension contributions are already out of both figures, and rerun it whenever either of you changes job or hours.

Whose name should go on each bill?
The supplier bills the person named on the account, so whose name goes where decides who it chases.
- Energy: Citizens Advice says that if your name is on the account you have to pay the bills, and that if another person will not contribute you will usually have to pay the whole bill and try to get the money back afterwards.
- Council tax is not chosen this way. GOV.UK says spouses and partners who live together are jointly responsible for paying the bill.
- TV Licence: GOV.UK says you can have one licence for the whole household if you watch TV in a single shared area or have a joint tenancy agreement.
- A fair default is to spread the accounts, for example energy in one name and broadband in the other, and to write down who holds each one.

Should we open a joint bank account for bills?
It makes paying shared bills simple, and it links your credit files while it stays open.
- Experian says opening a joint bank account creates a financial association, which links your credit report to your partner's.
- Moving in together or getting married does not create one on its own: Experian says just sharing an address or being married does not.
- Lenders may check a financial associate's credit history when you apply for credit, so one partner's record can affect the other's.
- If you separate, Experian says you can ask the credit reference agencies to remove the association once you no longer share finances, after closing joint accounts.

What happens to council tax when a partner moves in?
If you were living alone, the 25% single person discount usually ends, and the council needs to know.
- GOV.UK says you get 25% off only if you live on your own or everyone else in your home is disregarded, and that a full bill is based on at least 2 adults.
- Worked example (Taupia's arithmetic): at England's average Band D of £2,392, a person living alone pays £1,794.00. Once a partner moves in the bill is £2,392.00, which is £598.00 a year more.
- If you keep a discount you are no longer entitled to, GOV.UK says you must contact your council, or you could get a fine and be asked to pay the discount back.
- Wales gives the same 25% when you are the only adult. In Scotland, mygov.scot says a discount for living alone also covers water and sewerage charges. Northern Ireland has domestic rates instead, with a 20% Lone Pensioner Allowance for people aged 70 or over who live alone.

What happens to the bills if you split up?
The accounts, the tenancy and the council tax each need sorting separately.
- Tenancy (England): GOV.UK says one joint tenant can usually end a joint periodic tenancy without the other's agreement, and that a joint tenant who wants to stay after notice needs the other tenants and the landlord to agree.
- Accounts: whoever is named on an energy account has to pay it, Citizens Advice says, so ask each provider to change the account holder rather than just stopping paying.
- Council tax: if you now live on your own, apply for the 25% single person discount.
- Joint finances: close or transfer joint accounts, then ask the credit reference agencies to remove the financial association, as Experian describes.
- Re-split anything you still share, such as a final bill, by the rule you used before.

How do we set up the bills when we move in together?
Six steps, from listing the bills to keeping the split fair.
- 1
List every bill you will share
Energy, council tax, water, broadband and the TV Licence, plus anything else you agree to share. Mobile phones usually stay personal.
- 2
Agree 50/50 or a split by income
By income, each of you pays the same share of the bills as your share of your combined take-home pay.
- 3
Decide whose name goes on each account
The named account holder is the one the supplier pursues, so spread the names or keep a written note of who holds what.
- 4
Tell the council about the move
Register at the new address, and tell the council if a single person discount no longer applies.
- 5
Set up how you will pay
Pay from a joint account, or have each partner pay the other their share on a fixed date each month.
- 6
Review the split when your pay changes
A new job, a pay rise or reduced hours changes an income split, so recalculate rather than let it drift.

- It keeps your energy, broadband, mobile and water bills in one place and compares energy, broadband and mobile deals, switching only once your household approves.
- Taupia does not set up council tax or switch water, and it is free.
Questions couples ask about sharing bills
What is the fairest way for couples to split bills?
There is no single fair answer. YouGov found 48% of Britons think bills should follow earnings and 37% prefer 50/50, while among couples who both work and live together, 46% split 50/50 and 38% by income. Pick the rule you both think is fair and agree it before the first bill.
How do you split bills by income?
Divide each partner's take-home pay by your combined take-home pay, then apply that percentage to the bills. With pays of £2,400 and £1,600 a month, the split is 60% and 40%, so £442.86 of monthly bills becomes £265.72 and £177.14.
Does my single person discount stop when my partner moves in?
Usually, yes. GOV.UK gives 25% off only if you live on your own or everyone else in your home is disregarded. Tell your council when your partner moves in: GOV.UK says that if you keep a discount you are not entitled to, you could be fined and asked to pay it back.
Should we have a joint account for bills?
It makes shared bills easy to pay, but Experian says opening a joint bank account creates a financial association that links your credit reports, which living together or marriage alone does not. If you later separate, you can ask the credit reference agencies to remove it once your finances are no longer shared.
Whose name should the bills be in when we move in together?
Spread them. Citizens Advice says the person named on an energy account has to pay the bills, so putting every account in one name puts all the risk on one person. Council tax is different: GOV.UK says partners who live together are jointly responsible for it whoever's name is on the bill.
What happens to joint bills if we break up?
Ask each provider to change the account holder, apply for the single person discount if you now live alone, and close or transfer joint bank accounts. In England, GOV.UK says one joint tenant can usually end a joint periodic tenancy without the other's agreement.
