How letting agents check you can afford the rent
Before offering you a tenancy, the letting agent or a referencing company checks your income and credit. The test most of them apply is simple: your yearly income before tax should be at least 30 times the monthly rent (or monthly pay of 2.5 times the rent — the same test). It is a convention, not law, and agents vary: some count savings, some ask for more. Passing it doesn’t guarantee an offer; it is the first filter, not the decision.
The 30× rule and the 36× guarantor rule
For you: 30 × monthly rent ≤ your yearly income before tax. So the most you pass on is your salary divided by 30: £24,000 allows £800 a month and £36,000 allows £1,200.
For a guarantor: 36 × monthly rent ≤ their yearly income before tax. A guarantor agrees to pay if you don’t, so agents set a higher bar — £43,200 a year for a £1,200 rent.
Why a comfortable budget is lower
The agent check uses pay before tax. A comfortable budget starts from what reaches your account: rent of about 30% of take-home pay leaves room for council tax, energy, travel and saving. On £35,000 the agent check allows £1,166 a month, but 30% of an estimated £2,393 take-home is £717. The estimate uses 2026/27 income tax and National Insurance, before pension and student loan; type in your own figure if you know it. MoneyHelper’s budgeting tools help with the rest of your outgoings.
Renting with someone else
Most agents add joint applicants’ incomes together — two people on £20,000 each pass on rent up to £1,333 a month — though some check each person against their share. Joint tenants are each responsible for the whole rent, not just their half.
Self-employed, contractors and students
If you’re self-employed, agents usually ask for one or two years of accounts or HMRC’s SA302 tax calculations, and may average your profit. Contractors are often assessed on their contract and day rate.
Students rarely have income that passes, so agents ask for a guarantor, often a parent. In England, since 1 May 2026, a landlord can’t take rent before the tenancy agreement is signed, then can ask only for the first month’s rent (28 days if rent is weekly) before it starts (Housing Act 1988, s.4B; GOV.UK guidance). So paying months up front is no longer a condition a landlord can set there, though once the tenancy has started you can choose to pay early. Scotland, Wales and Northern Ireland have their own rules.
Guarantors and rent guarantor services
A guarantor promises to pay your rent — and, depending on the agreement, damage costs — if you don’t. Many agents want one who lives in the UK; some ask for a homeowner. On a joint tenancy, check whether they cover only your share or everyone’s rent — Shelter explains what a guarantor can be asked to pay. If nobody can be your guarantor, a joint application, a smaller home or a rent guarantor service (a company that acts as guarantor for a fee) are the usual options; ask whether the agent accepts a service and read what the fee covers. Dwellio doesn’t recommend or earn from any of them.
Worked examples, on today’s listings
One earner each, on UK tax bands outside Scotland.
£28,000 in Leeds
£28,000 ÷ 30 = £933 a month, the rent a typical agent check allows; a guarantor for it would need £33,588 a year. Take-home is about £1,973 a month, so a comfortable rent is £591. The median pay of employees living in Leeds is £31,679 a year before tax (ONS, 2025).
In Leeds now: 337 1-beds, 164 2-beds, 18 3-beds and fewer than 5 4+ beds are listed at or under £933 a month. The median asking rent of the 526 1-beds listed there is £875 a month, which needs £26,250 a year — within this salary. Leeds rents by size

Questions renters ask
How much rent can I afford on £30,000 a year?
On a £30,000 salary the usual letting-agent check allows rent of up to £1,000 a month, because agents look for a yearly income of at least 30 times the monthly rent. A comfortable budget is lower: 30% of an estimated £2,093 monthly take-home is £627.
What is the 30 times rent rule?
It is the income check most letting agents use: your yearly income before tax should be at least 30 times the monthly rent, so a £1,000-a-month home needs £30,000 a year. Some put it as monthly pay of 2.5 times the rent, the same test. It is common practice, not law, and some agents ask for more.
How much does a guarantor need to earn?
Usually at least 36 times the monthly rent before tax, which is £43,200 a year for a £1,200-a-month home. Many agents also want a guarantor who lives in the UK, and some ask for a homeowner.
Do letting agents use gross or net income?
Gross: your pay before tax and National Insurance. That is why the agent check can allow a rent that takes close to half your take-home pay; 30% of take-home is the safer number to plan around.
Can two people combine their incomes to rent?
Usually, yes. Most agents add joint applicants’ incomes together, so two salaries of £20,000 support rent of up to £1,333 a month. Some check each person against their share instead, and joint tenants are each responsible for the whole rent.
Does the calculator work in Scotland, Wales and Northern Ireland?
Yes. The 30 and 36 times checks are used across the UK, and the take-home estimate uses Scottish income tax bands for Scottish towns and UK bands elsewhere, for 2026/27.
