Letting agents typically use the “30x rule” to check a tenant can afford the rent: your gross annual income should be at least 30 times the monthly rent. Enter a monthly rent below to see the income you'd need.

With Brick Rewards
Earn£0in rewards each month from paying your rent.
The 30x rule is the affordability check most UK letting agents and referencing agencies run before approving a tenancy application. It compares your gross (pre-tax) annual income against the rent you're applying for, on the assumption that rent shouldn't swallow more than around a third of your income. The maths is simple: multiply the monthly rent by 30, and that's the minimum annual income a landlord will typically look for.
It's a useful rule of thumb before you start viewing properties, too - working out your budget up front means you can filter out listings you're unlikely to pass referencing for, rather than falling in love with a flat you can't afford.
Income is only one part of a standard reference check. Landlords and letting agents typically also look at your credit history, employment status and references from a current or previous landlord, and may ask for a guarantor if you're a student, new to the UK, or self-employed with a shorter income history. In many cases they also want to see stable employment, a consistent payment record, and enough money left after rent to cover living costs.
Why Brick Rewards helps: By encouraging timely rent payments and stronger financial habits, Brick Rewards can support a healthier renting profile while giving tenants rewards on the rent they already pay - a simple way to make paying rent more valuable for both renters and landlords.
| Monthly rent | Annual income needed (30x) |
|---|---|
| £600 | £18,000 |
| £800 | £24,000 |
| £1,000 | £30,000 |
| £1,200 | £36,000 |
| £1,500 | £45,000 |
| £2,000 | £60,000 |
The 30x rule means your gross annual income should be at least 30 times the monthly rent. For example, £1,000 a month in rent would need a gross annual income of at least £30,000. The calculation is £1,000 × 30 = £30,000.
It's a quick, standardised way to check a prospective tenant can comfortably afford the rent without spending too much of their income on housing costs. Most referencing agencies and letting agents in the UK use it as a first-pass affordability check before a full reference is run.
No — gross income is your salary before tax, National Insurance, and other deductions. The 30x rule is based on gross (pre-tax) annual income, not the take-home amount that lands in your bank account.
Yes, most letting agents will combine joint tenants' gross incomes and check the total against 30 times the monthly rent, rather than assessing each tenant individually.
Some landlords will still consider you with a guarantor, a higher deposit, or by paying rent in advance — affordability criteria vary, so it's worth checking directly with the landlord or letting agent.
Brick Rewards turns your rent payments into points you can redeem with partner brands — it won't change your affordability check, but it does put some value back into your monthly rent spend.
Once you know what you can afford, Brick Rewards helps you get more from every rent payment - earn points just for paying on time, then spend them with brands you already shop at.
