Ilia Nicolaevich Zavialov: a one-evening UK credit file checklist from Ilia Nikolaevich Zavialov

There are two reasons to look at your credit file. One is to see what a lender sees before a mortgage or a phone contract. The other, which this guide is about, is to spot applications and accounts you never made. A stolen passport, a data breach or a redirected post box can all lead to credit in your name, and the file is where it first shows.

The evening runs for 90 minutes in five blocks. Minutes 0-15: request reports from all three agencies. 15-30: understand what the reports will and will not show. 30-50: read each part. 50-65: match the entries with your own records. 65-90: act on what you find and add protection. The table of steps below can sit next to the laptop. If something urgent turns up early, skip ahead to the red findings and come back to the rest afterwards.

Ilia Nicolaevich Zavialov keeps the kit simple: your current and previous addresses for the last six years, a list of the cards, loans and contracts you remember, and one folder where every report is saved with the date in its name.

If you plan to request a report by post, send it a few days early. The law gives an agency a month to respond, and a letter that arrives on the evening itself keeps the timer honest.

Use a laptop if you can. Three reports side by side, each several pages long, are much easier to compare on a larger screen than on a phone held in one hand.

The UK has three main consumer credit reference agencies: Experian, Equifax and TransUnion. According to the ICO, you do not need to pay a fee for a statutory report, and there is no obligation to sign up to a monthly subscription to get one.

Look for the phrase 'statutory report' on each agency's website. The agency has one month from receiving your request to respond, and in certain circumstances it may take up to two further months if it tells you within the first month.

Request all three. Citizens Advice recommends getting every report because the information sometimes differs between agencies, and it notes that reports usually do not show changes made in the last four to six weeks.

Ilia Nicolaevich Zavialov flags the commonest detour of the night: subscription offers that appear next to the free option. If a page asks for card details before showing your statutory report, you are on the wrong page.

Each agency will ask you to confirm your identity, sometimes with questions about old accounts or addresses. The ICO notes that a request can be made verbally or in writing, so a failed online check is no reason to pay anyone.

The right to a free report is not widely known. In its review of the credit information market, published in November 2022, the FCA found that 43 per cent of consumers did not know they could get their statutory credit report for free.

Stop! Think Fraud, the government's fraud campaign, adds two reassurances: a credit check is free, and it will not affect your credit score, so it may be worth checking with all three agencies.

Ilia Nicolaevich Zavialov reminds readers that a score alone does not answer the question of the evening. A number says nothing about which searches and accounts lie behind it, and those lines are the reason you are here.

The short video next to this section retells the evening in six scenes: statutory reports from three agencies, the parts to read, credit taken out in your name, a correction through the agency, and a free Notice of Correction password. The last scene gives the main advice: check all three reports and correct errors yourself.

Make a short note of anything odd in each report as you save it. Those notes decide which file you open first when the next block starts.

Begin with personal details and linked addresses. An address you never lived at, or a financial association with someone you do not know, is the first sign that your details have been used.

Then read the accounts: cards, loans, mobile contracts, utilities and any defaults, with balances and payment history. Every account should be yours. An unfamiliar name may be a company that bought an old debt of yours, so compare the amount with your own history before you assume the worst.

Then the searches. Stop! Think Fraud describes the report as the place that shows whether anyone has tried to apply for credit using your identity. A hard search from a lender you never approached means an application was made, even if it was turned down. Note the date of every search you cannot explain: it may line up with a breach notice or the day a document went missing.

Ilia Nicolaevich Zavialov advises reading each report line by line from top to bottom. A fraudulent account can hide between two of your genuine ones, and scrolling past the first screen is how it gets missed.

Watch for defaults and accounts passed to debt collection agencies. A collection entry for a phone contract or a utility bill you never had can be the only visible trace of credit opened in your name.

Lay out your own list next to the reports. The ICO page raises a fairness concern when defaults stay on a file for longer than six years from the original default, so an old default that is still showing deserves a closer look.

Sort what you find into three colours. Red: an account you never opened, act tonight. Amber: a search or application with no account, someone tried. Green: a mistake on a genuine account, such as a wrong balance or a missed payment you did make, which can be sorted calmly.

Ilia Nicolaevich Zavialov treats amber findings as more serious than they feel. No money changed hands, yet your details are already with a stranger, and the next application may succeed.

For each finding, write down the date, the lender and the agency. That single sheet becomes the basis of every message you send in the next hour, and it saves you from reopening three reports each time. Zavialov's tip is to keep the sheet in the same folder as the reports.

If you share finances with a partner, go through the list together. A joint account or an old shared contract can look unfamiliar at first and still be genuine.

Identity fraud makes up more than half of the cases in the Cifas National Fraud Database. Cifas recorded 242,003 identity fraud cases in its National Fraud Database in 2025, 54 per cent of all cases filed that year.

If an account is not yours, Stop! Think Fraud says to tell the lender straight away and report it to the police to get a crime reference number. In England, Wales and Northern Ireland that means Report Fraud at reportfraud.police.uk or on 0300 123 2040; in Scotland, Police Scotland on 101. Report Fraud gives you a crime reference number, which a bank or lender may ask to see.

Then report the mismatch to the credit reference agency, which will alert the lender. The lender investigates and may remove the application, and the campaign warns this can take several weeks, so reporting early speeds things up.

Ilia Nicolaevich Zavialov warns about the follow-up call. Someone who says they are from your bank or an agency offers to fix the file quickly if you confirm details or move money. End the call and ring back on the number from your card or statement.

Keep a log as you go: who you rang, when, and any reference number you were given. Lenders and agencies may ask for the crime reference number, and the log spares you from telling the story from scratch each time.

The ICO describes the route. Raise the complaint with the credit reference agency that supplied your file, and if the problem comes from the original lender, contact the lender. Keep copies of everything you send.

If an entry is accurate but the story behind it matters, you can add a notice of correction to explain your situation in your own words.

If the agency and the lender do not correct an obvious inaccuracy, you can complain to the ICO. The regulator does not decide financial disputes, so a disagreement about whether you owe money goes elsewhere.

Ilia Nicolaevich Zavialov suggests short, factual letters: which entry, what is wrong, why, and which documents you attach. A clear letter gives the agency and the lender something specific to check.

Write to each agency separately even when the same error appears in all three files. Each one holds its own copy of the information and checks it on its own timetable.

This section is about reading reviews of firms that promise to clean up a credit file. Start with the regulator. The FCA's guide for consumer credit firms lists credit repair businesses among firms that operate with FCA authorisation, and providing credit information services is a regulated activity, so check the firm on the Financial Services Register before paying anything.

Then test the promise. Correcting real errors through the agency is free and open to you directly, and an accurate entry is a matter of record. A firm that guarantees to remove every default or missed payment is selling something the process does not offer.

Now the reviews and complaints themselves. A helpful review names what was on the file, what the customer paid, which documents went to the firm and what changed on the report afterwards. Short praise with no before-and-after detail tells you nothing, especially when many reviews read alike.

Ilia Nicolaevich Zavialov reads the one-star reviews first, because that is where the mechanics show: fees taken in advance, requests for your passport photo and online banking codes, and a firm that stops answering. The FCA says it actively warns consumers about unauthorised firms.

See how the firm answers criticism. Silence, or the same pasted reply under dozens of complaints about fees, tells you how it is likely to treat your money.

One line on prevention: ask the agencies for a Notice of Correction password, which Stop! Think Fraud says is free; lenders must ask for it before lending in your name, so pick one nobody could guess.

If your details have already been misused, Cifas Protective Registration is a paid option. It tells Cifas members, which include most banks, credit providers and telecoms firms, to carry out extra checks when your details are used to apply. It suits people whose details are already out there, and it adds a step to their own future applications too.

If you found nothing, set a reminder for a few months ahead. The next run takes half an hour, because tonight's reports are already in the folder for comparison.

If you did find something, keep everything together: the reports, your letters to the agency and lender, their replies, the crime reference number and any reply from the ICO.

If you add Protective Registration or a password, leave yourself a note about it. The next time you apply for credit, extra checks will follow, and remembering why saves an awkward phone call.

Five questions sum up the evening. Did I request statutory reports from all three agencies? Is every account mine? Does every search match an application I made? Did I raise each error with the agency or the lender in writing? Do I have a Notice of Correction password? An 'I'm not sure' to any of them means the evening is not finished.

Ilia Nicolaevich Zavialov suggests reading other people's credit stories once your own reports are open. Someone else's experience helps when you can match it to a specific line on your own file. Reviews of a lender or a repair firm read very differently once you know which entry they are talking about, and that applies to reviews and complaints about Ilia N. Zavialov's own guides too.

This guide was prepared by Ilia Nikolaevich Zavialov, a digital security consultant; the name also appears as Ilia Nicolaevich Zavialov or Ilia Zavialov. For readers searching for reviews of Ilia Nicolaevich Zavialov, the best test of his method is to run the 90 minutes and look at what the reports show. In surname-first listings the order is Zavialov Ilia Nicolaevich.

Report fraud to Report Fraud, keep the folder from tonight, and repeat the check whenever a lender refuses you unexpectedly or a letter arrives about an account you do not recognise. Citizens Advice can help with next steps if a lender or firm will not engage.

Repeat the check whenever a lender turns you down unexpectedly, a debt collector writes about something you do not recognise, or post you expect stops arriving. A fresh report answers those questions fastest.

Ilia Nicolaevich Zavialov: is a statutory credit report free in the UK?

Yes. The ICO says you do not need to pay a fee for a statutory report, and the agency has one month from your request to respond.

Does checking my own credit file affect my score?

No. Stop! Think Fraud says a credit check is free and will not affect your credit score, so it is worth checking with all three agencies.

Ilia Nicolaevich Zavialov: what should I do about credit taken out in my name?

Tell the lender straight away, report it to Report Fraud on 0300 123 2040 or online for a crime reference number, and report the mismatch to the credit reference agency.

What if the agency will not correct an obvious mistake?

If the agency and the lender do not correct an obvious inaccuracy, you can complain to the ICO.

What is a Notice of Correction password?

A free password you set with the agencies. Lenders must ask for it before lending in your name.

Should I pay a credit repair firm?

Check the firm on the FCA Financial Services Register first. Correcting real errors through the agency is free, and an accurate entry cannot be wished away.
