Credit scores used to be based on a small slice of your financial life, which meant one late payment years ago could follow you around like a shadow.
Now, companies like Experian are changing what counts, folding in new data that paints a wider picture of how you manage money. On the surface it sounds helpful, even fairer, but depending on how you live and spend, it could just as easily trip you up. Here’s what you need to know and what it might mean for you.
The scoring range has expanded massively.
Experian’s moved from a 0-999 scale to 0-1,250, giving a much more detailed breakdown of where you stand. This isn’t just adding numbers, it’s completely redefining how creditworthiness gets measured. That’s why 44% of people will drop down a band, while 41% move up and 14% stay the same. The changes reflect the new scale rather than your finances actually worsening, so don’t panic if your band drops.
Rental payments now count towards your score.
For the first time ever, paying rent on time will boost your Experian credit score. This is massive for renters who’ve been building zero credit history despite their biggest monthly payment being reliable. It helps if you opt in to have rental payments included, as it won’t happen automatically. Contact your landlord or letting agent about rental reporting schemes to start building credit from your rent.
Missing rent will now damage your score.
The flip side of rent counting positively is that late or missed payments will hurt your score just like any other credit. Your landlord’s records become part of your credit history, whether you like it or not. You’ll notice this creates real consequences for rental arrears that didn’t exist before. Prioritise rent payments the same way you would credit card bills because the impact on your score is now identical.
Overdraft use is being watched more closely.
The new system penalises regular overdraft use much more heavily than before. Lenders see persistent overdraft reliance as a sign you’re struggling to manage money within your means. That’s why you should work on reducing overdraft dependency if you use it monthly. Even small reductions in how often you dip into your overdraft will positively impact your score under the new system.
Credit card cash advances are a major red flag.
Using your credit card to withdraw cash has always been expensive, but now it damages your credit score significantly. Lenders view it as desperate behaviour indicating financial distress. It helps if you find alternative ways to access cash when needed. Personal loans or even asking family for help look better on your credit file than repeatedly using credit card cash advances.
Phone contract payments matter more than before.
Regular mobile phone contract payments are now weighted more heavily in your score. Consistent payments demonstrate reliability, while late payments or frequently switching providers raises red flags. You’ll notice paying your phone bill on time is no longer just about avoiding disconnection, it’s actively building your credit score. Set up direct debits to ensure you never miss a payment.
The old “poor” and “very poor” labels have gone.
Experian’s replaced stigmatising language with “fair” and “low” to be less demotivating. The red warning colours are gone too, making the experience less anxiety-inducing when checking your score. The psychological impact of checking your score should feel less crushing. The change recognises that negative labelling discouraged people from engaging with their credit health.
Mortgage overpayments are now recognised.
Making extra mortgage payments beyond your minimum shows financial discipline and now gets rewarded in your credit score. It demonstrates you’re managing money well enough to pay more than required. It helps if you make occasional overpayments when you can afford it. Even small additional payments signal to lenders that you’re financially stable and capable of handling credit responsibly.
Your actual borrowing eligibility hasn’t changed.
Despite all these changes, Experian stresses your ability to get mortgages, loans, or credit cards remains exactly the same. Lenders still assess applications using the same criteria as before. This means the new score is about transparency rather than making lending harder or easier. It’s showing you the same information lenders have been using anyway.
People with thin credit files benefit most.
If you’ve struggled to build credit history because you rent and don’t use traditional credit products, the new system finally recognises your financial responsibility through everyday payments. That’s why young people and renters should see the biggest positive impact. The system now captures more of how you actually manage money, rather than just formal credit products.
Provider switching frequency gets tracked.
How often you switch mobile providers, energy suppliers, and other services is now part of your credit assessment. Constant switching can signal instability, while staying put suggests reliability. It helps if you balance getting good deals with maintaining some consistency. Switching for genuine savings makes sense, but constant changes purely for small gains might hurt your score.
The changes rolled out automatically.
Your Experian score updated automatically between November and December 2025. You received an email when your new score became available, with no action required on your part. You’ll notice you can access the new system through the free Experian app or paid service. The free version shows indicative impacts, while the premium £14.99 monthly service offers detailed personal assessments.
You can see exactly what affects your score.
The new system shows percentage breakdowns of how different factors influence your score. You’ll get personalised actions to improve with forecasts showing potential point gains from specific changes. As a result, improving your score becomes more strategic and less guesswork. You can prioritise actions based on their actual impact rather than following generic advice.
This only affects Experian, not other agencies.
The UK has three main credit reference agencies, and this change only applies to Experian. Equifax and TransUnion still use their old systems, meaning your scores with them haven’t changed. It helps if you check all three agencies to understand your complete credit picture. Lenders use different agencies, so knowing all three scores gives you the full story.
Your credit report matters more than the number.
Lenders don’t actually use your credit score number when making decisions. They look at the detailed information in your credit report, the score is just Experian’s interpretation of that data. You’ll notice this means obsessing over the exact number misses the point. Focus on the underlying credit report information because that’s what actually affects lending decisions, not the score itself.
