How to build a credit score from nothing

First, what lenders actually look at

There isn't one magic number. In the UK, your credit file is held by credit reference agencies, mainly Equifax, Experian and TransUnion. It lists things like your accounts, how you've paid, your address history and whether you're on the electoral register. Each agency turns that into its own "score", and each lender then uses its own rules on top. So a score is a rough guide, not a verdict.

A "thin" file just means there's not much on it yet. It's not a bad file. It's a blank page. Meet the agencies properly in Meet the reference agencies.

Step 1: register to vote at your address

This is the easiest win there is. Being on the electoral register helps lenders confirm you are who you say you are and live where you say you live. It takes about five minutes online on GOV.UK. Moved for uni or a new flat? Register at the new address. You can opt out of the "open register" (the version anyone can buy) and still be on the full one. More in Prove you exist.

Step 2: check your file for free

You have a legal right to see your statutory credit report from each agency free of charge. Look for that phrase on their websites. You don't need a paid subscription. Checking your own file is a soft search, so it never harms your score, no matter how often you look.

While you're there, check every address and account is right. If something is wrong, ask the agency to correct it, or add a short notice of correction explaining your side. Never check your file through a link in a text or email, because that's a classic scam.

Step 3: let your everyday bills do some work

A UK current account, used normally, shows up on your file. So can a mobile phone contract and some utility accounts. Paying them on time, every time, is the single most important habit. Setting up direct debits means you can't forget.

Step 4: one small, boring line of credit (only if it fits your budget)

Some people choose a credit card with a low limit, put one regular bill on it (like their phone), and pay the full balance by direct debit every month. That shows lenders you can borrow and repay without paying any interest at all. This is a personal choice, not advice, and it only works if you never carry a balance.

Two habits make it work:

• Keep usage low. Using a small part of your limit looks better than maxing it out. Our lesson The utilisation situation explains why.
• Don't apply for lots at once. Each full application leaves a hard search. Several in a short time can look like you're desperate for credit. Eligibility checkers that use a soft search are fine.

Step 5: give it time

Credit history is literally history. Six months of on-time payments is good. Two years is better. There's no hack that skips this, whatever a TikTok "credit repair" guru says. Building credit is like growing a sourdough starter: you mostly just have to not kill it.

Myths that waste your time

• "Checking my score lowers it." No, your own checks are always soft searches.
• "I need to borrow and pay interest to build credit." No, paying in full every month works and costs nothing.
• "Debt from my flatmate affects my score." Only if you're financially linked, for example through a joint account or joint loan. Sharing an address isn't enough.
• "Student loans wreck your credit." Loans from the Student Loans Company don't appear on your credit file.
• "Paying someone can wipe bad marks." Only wrong information can be corrected, and you can ask for that yourself for free. Anyone promising to delete accurate entries for a fee is selling you something you can't have.
