A popular way is to split the rent in proportion to your incomes: on £1,400 rent with gross salaries of £45,000 and £25,000, that is £900.00 and £500.00 a month. The other main options are 50/50, a split based on take-home pay after essentials, or equal rent with the higher earner paying more of the bills. Whatever you agree between you, on a joint tenancy in England the landlord can usually ask either of you for the whole rent.
The four main ways to split rent
There is no legal rule on how a couple divides rent between themselves. It is a private agreement. These are the four approaches most couples choose from.
- 50/50. Each of you pays half. Simple, but it takes a much bigger bite out of the lower income.
- Proportional to gross income. Each of you pays the same percentage of your salary. Easy to work out from payslips or contracts.
- Proportional to take-home pay after essentials. You start from what actually lands in each account, then subtract fixed costs such as student loan, travel to work, childcare or debt repayments. This is closer to what each of you can really afford, but it takes more agreement on what counts as “essential”.
- Equal rent, unequal bills. You split the rent 50/50, and the higher earner covers more of the energy, broadband, council tax or food. This can feel fairer to the person who wants their name on half the rent.
Worked example (fictional)
Alex earns £45,000 a year and Sam earns £25,000. Their rent is £1,400 a month.
Combined income is £70,000. Alex earns 45/70 of it, and Sam earns 25/70.
- Alex: £1,400 × 45,000 ÷ 70,000 = £900.00
- Sam: £1,400 × 25,000 ÷ 70,000 = £500.00
- Check: £900.00 + £500.00 = £1,400.00
| Method | Alex pays | Sam pays | Share of gross monthly pay |
|---|---|---|---|
| 50/50 | £700.00 | £700.00 | Alex 18.67%, Sam 33.60% |
| Proportional to gross income | £900.00 | £500.00 | Both 24.00% |
Gross monthly pay is £3,750.00 for Alex (£45,000 ÷ 12) and £2,083.33 for Sam (£25,000 ÷ 12). Under a 50/50 split, Sam spends a third of gross pay on rent. Under the proportional split, both spend 24%.
Using take-home after essentials (fictional)
Say Alex takes home £2,900 a month and has £500 of essential fixed costs, leaving £2,400. Sam takes home £1,750 with £450 of essentials, leaving £1,300. Together that is £3,700.
- Alex: £1,400 × 2,400 ÷ 3,700 = £908.11
- Sam: £1,400 − £908.11 = £491.89
The result is close to the gross-income split here. It can move a lot further if one of you has large fixed costs, such as childcare.
Equal rent, unequal bills (fictional)
Alex and Sam each pay £700 rent. Alex also covers £300 a month of household bills. Alex pays £1,000 in total and Sam pays £700.
What the landlord sees: joint liability
Your private split does not bind the landlord. If you are both named on a joint tenancy in England, Shelter’s advice is that “you are all responsible for the whole rent even if you pay different amounts”. If one of you does not pay, the landlord can ask the other to make up the missing rent.
So if Sam lost their job and could not pay £500, the landlord could ask Alex for the full £1,400. Shelter Scotland gives the same picture for joint tenancies in Scotland: everyone is responsible for all of the rent, and the landlord can ask the other tenants to pay the debt.
It is worth agreeing in advance what happens if one of you has a drop in income, and keeping a small shared buffer for rent.
Choosing a split that lasts
- Agree the method, not just the number. Then you can update it when a salary changes.
- Write it down, even in a shared note. It avoids arguments later.
- Decide how bills, food and savings fit in. A proportional rent split with 50/50 bills can undo some of the fairness.
- Review it once a year, or when either of you changes job.
- Check you can afford the whole rent between you before you sign. Letting agents usually look at your combined income. See our guide to joint income and rent affordability and how letting agents calculate rent affordability.
Work out your own split
Use the rent split calculator to compare a 50/50 split with an income-based split for your own rent and salaries. It shows each person’s share to the penny, so you can talk it through with real numbers.
