Credit Score Differences: UK, Spain and the USA

---

If you arrived in the UK with years of good financial behaviour in your home country — cards paid on time, loans fulfilled, a good score in DataCrédito, Buró de Crédito, or whatever system applied — here's a piece of news that surprises almost everyone: as far as banks here are concerned, you're starting practically from zero. Credit history doesn't cross borders automatically. Understanding why, and how the British system compares to the Spanish and American ones, is the first step to building your financial life in the UK without frustration.

What is a credit score?

A credit score is a number that summarises, for banks and lenders, how likely you are to repay what you borrow. It’s calculated from your credit history: your cards, loans, bills, and how you’ve paid them.

Think of it as a “financial CV.” Just as an employer in London can’t call your old boss in Bogotá or Lima without your help, a British bank can’t see — with a few exceptions we’ll cover — what you did with your cards back home.

The key point: each country has its own system

There’s no international credit score. Each country has its own agencies, its own scales, and even different philosophies about what gets recorded. That’s why:

• Your score in DataCrédito (Colombia), Buró de Crédito (Mexico), Serasa (Brazil), or Equifax/Veraz (Argentina) isn’t visible to a UK bank.
• An excellent US FICO score doesn’t work directly in London either.
• And the reverse is true too: if you ever move back to your home country, your British history won’t travel with you.

1. What the data says — three countries, three systems

In the UK, there’s no single official score

Each agency has its own scale and formula: Experian uses 0–999, Equifax 0–1000, and TransUnion 0–710. What’s more, the number you see is only indicative — each bank runs its own internal calculation on top of that data. That’s why your score can vary between platforms even though you haven’t done anything wrong.

A very British detail: being on the electoral roll improves your profile, because it verifies your identity and address. This is a real obstacle for many Latin Americans: only British, Irish, Commonwealth citizens, and in some cases EU citizens, can register. According to Equifax UK, if your nationality doesn’t allow you to register, you can add a “Notice of Correction” to your file explaining your situation, so lenders take it into account.

Spain: no universal positive score — it works “in reverse”

Spain is the most different of the three cases. According to the Bank of Spain, there’s the CIRBE (Central Credit Register), which records loans and guarantees above €1,000, but it isn’t a register of defaulters and doesn’t generate a score for the consumer.

What matters most in Spain are the negative files, such as ASNEF (managed by Equifax): lists where you only appear if you left a debt unpaid. In other words, the Spanish system mainly records the bad; it doesn’t systematically reward good behaviour with a visible number the way the UK or the US do. Each Spanish bank runs its own internal “scoring” using CIRBE data, the negative files, and your income information.

United States: the most standardised system

In the US, the FICO Score dominates — a 300 to 850 scale used by the vast majority of lenders (VantageScore also exists, on the same scale). According to FICO, the average score in 2025 was around 713–714 points, calculated with publicly known weightings: payment history (35%), credit utilisation (30%), length of credit history (15%), credit mix (10%), and new credit inquiries (10%).

Comparison table:

System	🇬🇧 United Kingdom	🇪🇸 Spain	🇺🇸 United States
Is there a standard score?	No: 3 agencies, 3 scales (Experian 0–999, Equifax 0–1000, TransUnion 0–710)	No: no universal consumer score	Yes: FICO (300–850) is near-standard
What gets recorded?	Positive and negative: on-time payments count in your favour	Negative (defaults in ASNEF); CIRBE records debts over €1,000	Positive and negative, very detailed
Main agencies	Experian, Equifax, TransUnion	CIRBE (Bank of Spain), ASNEF, Experian/Equifax Spain	Experian, Equifax, TransUnion + FICO model
Can I check my file for free?	Yes (statutory report and free apps)	Yes (CIRBE free via Bank of Spain)	Yes (annualcreditreport.com)
Does my foreign history count?	Rarely (exception: HSBC + Nova Credit)	Rarely	Exceptions via Nova Credit with some banks

What does this mean in real life? Arriving in the UK with “good credit” in your home country gives you no automatic advantage — but you don’t arrive “tainted” either: past financial mistakes don’t follow you. You start with a blank slate — and for a bank, a blank slate means risk. This is called being credit invisible. According to an Experian analysis, more than 5 million adults in the UK — around 9% of the adult population — are credit-invisible, and newly arrived people are one of the groups most affected.

2. Specific obstacles for Latin American migrants

Language (terms like APR, hard search, or default aren’t always understood right away), the impossibility of registering on the electoral roll for many nationalities, mistrust inherited from bad banking experiences back home, and jobs with variable or cash payments that make it hard to prove stable income.

Mini-glossary:

• APR: the total annual cost of credit, including interest and fees. A card with 30% APR means that if you owe £1,000 for a year, you’d pay around £300 in interest.
• Hard search: a check a bank runs when you apply for credit; it gets recorded, and too many in a row look bad.
• Soft search: a “soft” check (e.g. viewing your own score or using eligibility checkers); it leaves no trace visible to other banks.
• Default: when the bank declares that you’ve stopped paying a debt. It stays on your British file for 6 years.

3. What the system is doing

There’s real progress, though it’s still insufficient:

International history (the exception to the rule). In 2023, HSBC UK partnered with Nova Credit, a company that “translates” foreign credit histories into British format. According to HSBC UK, when applying for their credit card, you can voluntarily share your history from a list of countries that includes Brazil, Mexico, the Dominican Republic, and Spain, as well as the US, India, and others. HSBC reports this significantly increased approvals for newly arrived people. Important limitation: for now it’s practically the only British bank offering this, and the list doesn’t cover all of Latin America (Colombia, Peru, Ecuador, Venezuela, and Bolivia aren’t included today).

Rent reporting. Services that offer rent reporting let your monthly rent payment count toward your history with agencies like Experian — valuable, since paying rent on time is often a migrant’s first financial proof.

FCA Consumer Duty. Since 2023, the FCA has required banks and lenders to demonstrate that their products deliver good outcomes for consumers, with special focus on vulnerable customers — a category that can include language barriers.

“Credit-builder” products. Credit builder cards (low limits, designed for those starting) and savings schemes that report your payments to the agencies.

The gaps that remain. The system still assumes “standard” financial trajectories: stable address, continuous formal employment, electoral roll registration.

Experian acknowledges that, despite reducing the invisible population by more than 750,000 people since 2018, millions remain outside the system. And international portability of credit history is still the exception, not the norm.

4. What you can do

Concrete, free things you can do today:

• Once you get your first card: use it sparingly (ideally under 30% of the limit) and pay it off in full every month. This builds your score without paying interest.
• Open a British bank account if you don’t have one yet (traditional or digital banks like Monzo/Starling) and use it for everything, so your financial life leaves a trail.
• Put at least one bill in your name (electricity, internet, a mobile contract). A mobile contract is, for many people, their first British “credit.”
• Check your file for free at Experian, Equifax, or TransUnion (or apps like ClearScore/Credit Karma). It’s a soft search — it won’t penalise you.
• Check whether you can register on the electoral roll (it depends on your nationality and status). If you can’t, ask to add a Notice of Correction explaining why.
• Always use eligibility checkers (“check my eligibility”) before applying for any card — they tell you your odds without leaving a trace.

If you have credit history in Brazil, Mexico, the Dominican Republic, Spain, or the US, consider the HSBC UK card with Nova Credit to make the most of it.

Organisations that offer support:

• Citizens Advice (citizensadvice.org.uk): free guidance on debt, banking, and consumer rights; some offices offer support in Spanish.

• MoneyHelper (moneyhelper.org.uk): a free, government-backed public financial guidance service.

• StepChange and National Debtline: free, confidential advice if you already have problem debts.

• Latin American organisations in the UK (such as IRMO or ILATEC’s own network): support in Spanish and understanding of the migrant context.

If you feel a bank treated you unfairly, you can complain to the bank first and then to the Financial Ombudsman Service, free of charge.

CONCLUSION

Starting from zero financially says nothing about your responsibility or your history — it says something about how these systems are designed, systems that still can’t read trajectories that cross borders. Years of effort and good standing in your home country don’t disappear: the British system simply doesn’t have the eyes to see them yet.

Building a history here isn’t a test of your character; it’s a technical process that you master with information and patience. And while each person does their part, it’s also up to the system — regulators, banks, agencies — to do theirs: to design credit that recognises the real lives of those who migrate.

Financial inclusion isn’t a favour; it’s the condition for participating with dignity in the economic life of the country that is now also your home.
