Understandably, landlords the world over want assurance that a tenant can reliably cover the rent and bills – and a credit score is often assumed to be the clearest way to provide it. Therefore, anyone relocating to London from overseas would be forgiven for thinking the absence of a UK score is an immediate obstacle to a successful property search.
Credit histories don’t cross borders, no matter how long and healthy your financial track record back home. So, starting from zero can feel like a disadvantage before you’ve even begun. You’ll be relieved to learn that in practice the UK rental market is built around a different set of financial priorities – and for new arrivals, that’s largely good news.

UK rental system: the welcome reality

For overseas arrivals, the absence of a UK credit history is not an issue. Landlords understand that you haven’t had the chance to build one – and won’t hold it against you.
This isn’t just goodwill. The UK rental system is structured around forward-looking financial information rather than historical credit data for practical reasons. Your credit past, particularly one held in another country’s system, doesn’t answer their key question: Can this person reliably afford the rent and bills going forward?
What landlords actually consider: your future income

Rather than looking backwards at credit history, UK landlords and letting agents look forwards at your income. They do this to ascertain whether your earnings in the UK will meet what’s known as the affordability threshold.
The standard benchmark is that monthly rent should consume 30% or less of a household’s gross income. So, for example, if you’re looking at a flat with a rent of £3,000 per month, a landlord will typically require an annual income of at least £90,000. This threshold can vary. Landlords or letting agents sometimes apply a multiplier of 35 or even 40 times, depending on the property or their requirements.
What documentation will the landlord request?

Landlords will want confirmation in writing that your income meets the threshold. This typically requires you to provide:
- A formal employment contract from your UK employer, showing your salary and start date
- A letter from your employer on company letterhead confirming those details
- Recent pay slips if you’ve already started work
If you’re being transferred to London by your employer, a company relocation letter can help smooth the application process further.
What if your income doesn’t meet the threshold?

Not everyone arriving in London will have a UK income that hits the required threshold immediately – particularly if you’re starting a new role, working part-time, or moving ahead of a job starting. When this is the case, a private or professional guarantor is the solution.
Private guarantor
This is typically a friend or family member who agrees to cover the rent if you can’t. They must be UK-based and will be subject to their own referencing checks – including an income assessment.
Professional guarantor service
Sometimes called a rent guarantee service, this is a paid-for alternative if you don’t have someone to call on as a private guarantor. These specialist companies act as your guarantor in exchange for a fee – usually a percentage of the annual rent, paid upfront. They’re well understood by landlords and letting agents in London, making it a perfectly normal part of the rental process.
FAQs
![]()
> Will I fail a credit check if I have no UK credit history?
Most letting agents run a credit check as part of the standard referencing process, but a thin or non-existent UK credit history is expected for new arrivals. Instead, your income and employment documentation will be used to assess your financial suitability.
> What if I’m not starting my UK job until after I want to move in?
An offer letter or signed employment contract clearly stating your salary and confirming the role will typically suffice. This means you don’t have to have started work or received a pay slip before finding a rental property. A professional guarantor service can provide additional reassurance to a landlord while you’re in the gap between signing and starting.
> Do I need a UK bank account to rent in London?
Not necessarily at the point of applying, though you will need one set up before you move in as rent is almost always paid by bank transfer. Opening a UK bank account also helps you start building a credit history for the future.
> Can overseas bank statements help my application?
Yes. If you don’t yet have UK bank statements, providing overseas ones – particularly if they show savings or a consistent salary being deposited – can support your application and give the landlord additional confidence.
