Why Do You Need to Earn 3X the Rent to Rent a Home, And the need for A UK Gurantor.
Why Do You Need to Earn 3X the Rent to Rent a Home, And the need for A UK Gurantor.
For students, international renters and first-time tenants, the UK rental market can come with a bizarre requirement: you may need to earn several times the rent yourself, and then find someone who earns even more to guarantee you. Here's how guarantors actually work, and what you can do if you don't have one.
For students, international renters and first-time tenants, the UK rental market can come with a bizarre requirement: you may need to earn several times the rent yourself, and then find someone who earns even more to guarantee you. Here's how guarantors actually work, and what you can do if you don't have one.
First, let's talk about the ridiculous maths
Imagine you've found a flat for £1,500 a month, that is if you are trying to rent in London for example. You can afford it, you've budgeted for it. Maybe you have a job. maybe you are a student but, you have savings. Maybe you've even been paying rent somewhere else for years without missing a payment. Then the letting agent runs the numbers. Their affordability test says you need to earn 3X the annual rent. That's £18,000 a year in rent. So you need an income of, £54,000 a year. And if the agent uses a 4X multiplier? £72,000. Suddenly, a £1,500-a-month flat isn't really a £1,500-a-month flat. At least, not according to the spreadsheet, and here's where it gets even stranger. You don't meet the income requirement, so the agent asks you for a guarantor. But your guarantor may also need to demonstrate a sufficiently high income, have a good credit history, and sometimes own property or live in the UK. Which especially if you are an international student is quite difficult.
In other words, you don't earn enough to rent the property, so you need to find someone who earns enough to guarantee that you will. For students and international renters, this can become particularly absurd. A student might have their tuition and living costs covered by their family. An international student might have already demonstrated substantial funds to obtain their student visa. A recent graduate might have a signed employment contract but only a few months of payslips. A new arrival might have savings but no UK credit history. None of that necessarily fits neatly into an affordability calculator and that's the point worth understanding:
The 3X or 4X rent rule is not a legal requirement.
There is no general law in England saying that you must earn three or four times your rent before you can rent a property. These are affordability criteria used by individual landlords, letting agents or referencing companies. Landlords can assess whether they think you can afford the tenancy, and they can ask for things such as proof of income, bank statements, references, credit checks or a guarantor. They can also make a guarantor a condition of offering the tenancy, which happens quite often especially if they know you are a student (allegedly).
So if an agent says: “You need to earn 3× the rent.” That doesn't mean Parliament has decided that 3X is the magic number. It means that particular landlord, agent or referencing system has decided that 3X is the number they are comfortable with.
And that distinction matters.
So, what exactly is a guarantor?
A guarantor is someone who agrees to meet certain financial obligations under your tenancy if you don't. In the simplest version, that means: You don't pay the rent, your guarantor may have to pay it. Depending on the wording of the guarantee, the guarantor's liability can extend beyond rent. It can potentially include things such as damage to the property or other obligations under the tenancy. That's why it's very important to understand that being a guarantor isn't just a favour, it's a legal commitment. The guarantor should receive and read both the tenancy agreement and the guarantor agreement before signing. What they are actually liable for depends on the terms of that guarantee. And this is PARTICULARLY important with joint tenancies.
If four students rent a house together, they may be jointly and severally liable for the rent. Depending on how the guarantee is written, a guarantor could potentially become responsible for more than just their one individual share. So if your parents are signing a guarantee for your student house, don't simply skim the document and sign it, read what they're actually guaranteeing.
Why do landlords ask for guarantors?
From the landlord's perspective, it's fairly straightforward. They want another person who can be pursued for payment if the tenant doesn't pay. That's particularly attractive where the tenant is considered harder to assess financially, which FYI most are, by default. As such, landlords and agents are more likely to ask for guarantors from:
students
first-time renters
people moving to the UK from overseas
people with limited UK rental or credit history
people who don't pass the landlord's affordability test
people with certain credit problems
These are precisely the groups who may have the hardest time producing the kind of conventional financial profile a referencing system expects, which just so happens to create an unfortunate catch-22. You don't have a UK rental history because you've just arrived. Don't have a UK credit history because you've just arrived. You also don't have a UK guarantor because you've just arrived, and yet you're expected to have all three. Welcome to renting in Britain!
What if you don't have a UK guarantor?
This is where things get more interesting, and don't worry, all hopes not lost. Not having a guarantor doesn't automatically mean you cannot rent. There are several things you can try.
1. Firstly, ask whether the landlord will accept other evidence
If you fail an affordability test, ask what other evidence the landlord is willing to consider. Depending on the circumstances, that could include:
savings
bank statements
an employment contract
scholarship or sponsorship evidence
proof of regular income
previous landlord references
evidence of consistent rent payments
Shelter specifically suggests asking what evidence you can provide if it is difficult to demonstrate affordability in the usual way, including situations where you don't have a UK bank account.
2. Look for landlords with different requirements
One letting agent's affordability formula isn't necessarily the rule for every property in Britain. Some landlords may be more willing to look at your circumstances as a whole rather than relying entirely on a particular income multiplier. This is particularly worth considering if you're self-employed, newly employed, an international renter or someone with substantial savings but an unusual income profile. Failing one referencing system doesn't necessarily mean you're an unaffordable tenant.
It may simply mean you failed that referencing system.
3. Consider a professional guarantor
There are commercial companies that offer guarantor services.
Instead of asking your parents, sibling or friend to guarantee your tenancy, you pay a company to provide a guarantee, subject to its terms and eligibility requirements.
This can be particularly relevant to international students who don't have family in the UK. But read the terms very carefully! You're paying for the service, and the company may have its own affordability requirements. Shelter also points out that landlords and agents cannot force you to use one particular guarantor company if you need a guarantor service.
4. Check your university
If you're a student, don't overlook the people who deal with this problem every year: your university. Universities in a lot of cases have student housing advisers, hardship funds, lists of landlords who don't require guarantors, or other support for students struggling to secure accommodation. It's worth asking before assuming that your only option is to find a wealthy British relative you've never heard of.
5. Look into rent guarantee schemes
Some councils and charities operate rent guarantee schemes for people who cannot provide the usual financial security. Depending on the scheme, they may help with rent in advance, deposits or act as a guarantor. Eligibility varies considerably, so you'll need to check what's available where you're looking to rent. But it's another reason not to assume that “no guarantor” automatically means “no tenancy.”
And what about international students?
This deserves its own mention because international students can get caught in a particularly awkward version of the guarantor problem. You may already have demonstrated that you have enough money to support yourself in the UK for immigration purposes. For example, Student visa applicants generally need to demonstrate funds for their course and living costs, subject to the applicable rules and exemptions. But that doesn't mean a private landlord has to accept your visa financial evidence as proof that you meet their own affordability criteria. Immigration requirements and rental referencing requirements are two different things. So you can effectively find yourself proving your finances twice: First to the UK government, then to the letting agent. And the second test may still tell you that you need a guarantor.
The bottom line
A guarantor is not a strange legal requirement imposed on every renter in England.
It's a risk-management tool that a landlord can choose to require as a condition of letting a property. And the famous 3× or 4× rent requirement is generally an affordability policy, not a law. If you're a student, an international renter or simply someone who doesn't fit neatly into an affordability calculator, don't assume that failing the formula means you can't rent. Ask what evidence the landlord will accept. Check whether the requirement is negotiable. Look at other properties and landlords. Speak to your university or council. Consider a professional guarantor service if appropriate. And most importantly, understand what you're actually signing.
