Freeze Credit File UK 2026 — Notice of Correction at All Three CRAs
The UK doesn't have a true credit freeze like the US. The closest equivalent is a Notice of Correction — a free, indefinite text statement placed on your credit file at each of the three UK credit reference agencies (Experian, Equifax, TransUnion). It tells every lender pulling your file to apply manual review before approving credit. Total setup time: ~30 minutes across all three. No fee. No annual renewal.

Why the UK doesn't have a true credit freeze
In the United States, the Federal Trade Commission requires the three credit bureaus (Experian, Equifax, TransUnion US) to offer a free, true credit freeze: a lock on your file that prevents anyone — including you — from opening new credit until you unlock it. The UK has no equivalent. Three reasons:
- Regulatory framework difference. The UK Financial Conduct Authority regulates the lending side, not the CRA side; the Information Commissioner's Office regulates the CRAs but on data-protection grounds, not consumer-protection grounds. No regulator has mandated a freeze.
- Industry preference for friction-over-freeze. UK CRAs argue that complete blocking would harm consumers in time-sensitive credit applications (e.g. mortgage offers). The Notice of Correction is the industry-preferred middle ground: friction, not block.
- Alternative mechanisms. CIFAS Protective Registration (covered in detail here) handles the broader fraud-prevention surface. The UK's view is that CIFAS + Notice of Correction together exceed the protection of a US-style freeze.
In practice, the Notice of Correction works. Lenders are required by their FCA-regulated lending policies to manually review any application with an active Notice — this kills the speed-and-volume model that fraudsters rely on.
The standard Notice of Correction wording
Each CRA has slightly different procedures but they all accept the same general statement. Use this template (or your own variation):
"I have been a victim of fraud / identity theft (Report Fraud reference NF12345678). Please verify my identity in person or by phone call to my registered number on file before approving any credit, account, or service application using my name and date of birth. Do not rely solely on data-matched verification. If you cannot verify, please decline the application and contact me directly to discuss."
Customisation tips:
- Include your Report Fraud reference number if you have one — it shifts the perceived legitimacy of the marker significantly
- If you don't have one, replace with "no Report Fraud report filed; circumstance reported to my bank [bank name] on [date]"
- Keep total length under 200 words (Experian's hard limit; the others are softer)
- Don't include sensitive details (DOB, full address, account numbers) — anyone with file access sees the Notice
Experian — Notice of Correction process
Experian is the largest UK CRA. Their Notice of Correction process is the most polished. Two routes:
Route A: via Statutory Credit Report
You're entitled to a free statutory credit report from Experian. Apply at experian.co.uk/consumer/statutory-report. Once you have the report (or your CreditExpert account access), the form to add a Notice of Correction is in the report dashboard.
Route B: direct request
Write to:
Customer Support Centre
Experian
PO Box 9000
Nottingham
NG80 7WF
Or email: consumer.helpservice@experian.com
Include in the letter/email:
- Your full name, date of birth, current address
- All previous addresses for the past 6 years
- The full text of your Notice of Correction
- Photocopy of one photo ID (driving licence or passport) — Experian don't return originals so use a copy
- Photocopy of one proof of address (recent utility bill or bank statement)
- If applicable: copy of your Report Fraud report
Processing time: 7-14 working days. Experian email you when the Notice is live.
Equifax — Notice of Correction process
Equifax UK accepts Notice of Correction requests by post or online. The online route is via the Equifax Credit Report dashboard at equifax.co.uk. You'll need to register for the free Credit Report (or the paid Equifax monitoring service) first.
Postal route
Equifax Customer Service Centre
Equifax UK
PO Box 10036
Leicester
LE3 4FS
Include the same documents as Experian above. Equifax process Notice of Correction within 5-10 working days.
Online route
Log in to your Equifax Credit Report account. Navigate to "Personal Information" → "Add a Notice of Correction". Type the full text (up to 200 words). Submit. The Notice appears within 24-48 hours.
If you don't already have an Equifax account, registering is free and takes ~10 minutes. You'll need to answer a few identity verification questions based on existing credit history.
TransUnion — Notice of Correction process
TransUnion UK (rebrand of Callcredit until 2018) is the smallest of the three CRAs but still queried by many UK lenders, especially fintech and digital lenders. Critical not to skip.
Online route
Sign up for free credit report access at transunion.co.uk. Their dashboard has a "Submit Notice of Correction" form under Account → Privacy Settings.
Postal route
TransUnion Information Group
Consumer Services Team
One Park Lane
Leeds
LS3 1EP
Same documents as the others. Processing time: 5-7 working days.
The MyCreditMonitor option
TransUnion's free credit-monitoring tool (MyCreditMonitor) is worth signing up for separately. It alerts you to changes on your TransUnion file in real time — so if a fraudster does manage to push an application through despite your Notice, you find out within hours not weeks. Free; no credit-card required.
What lenders actually see
When a lender pulls your credit file, the Notice of Correction appears in a prominent position — typically right at the top of the report, above your transaction history. The lender's underwriting system flags the file as "Notice of Correction present — manual review required". Most UK lenders' policies state explicitly: a Notice-of-Correction file cannot be auto-approved; an underwriter must look at it.
What this means in practice:
- Volume fraud is dead. Fraudsters relying on script-based applications across multiple lenders get every application bounced to manual review. The economics don't work — they move to easier targets.
- One-off fraud attempts get caught. When the underwriter manually reviews and sees your Notice, their procedure typically requires phoning your registered number for verification. The fraudster doesn't have access to your phone — the application dies on verification.
- Your own applications still go through. Slower, but they go through. Allow 3-5 working days for credit-card applications, 7-10 for mortgage. For time-sensitive applications, mention the Notice up-front to the lender so they assign manual review at start.
When to use Notice of Correction vs CIFAS Protective Registration
Both are defensive markers. They overlap but cover different surfaces:
| Aspect | Notice of Correction | CIFAS Protective Registration |
|---|---|---|
| Cost | Free | £30 / 2 years |
| Duration | Indefinite | 2 years; renew if needed |
| Seen by | Lenders pulling your CRA file | Banks, telecoms, insurers, credit firms — CIFAS members |
| Covers credit applications | Yes | Yes |
| Covers bank account opening | Partial | Yes |
| Covers phone contracts | No | Yes (CIFAS-member telecoms) |
| Covers insurance applications | No | Yes |
| Setup time | ~30 min × 3 CRAs | ~10 min |
Recommended: Both. Set up Notice of Correction at all three CRAs (free, ~30 min) plus CIFAS Protective Registration (£30, ~10 min) for comprehensive coverage. The £30 buys you the CIFAS coverage layer that's invisible to credit-only checks.
Frequently asked questions
How often should I check my credit file after putting a Notice of Correction on?
Monthly for the first year, quarterly thereafter. Use the free credit-monitoring services (ClearScore for Equifax, Credit Karma for TransUnion, Experian's free Credit Report) — they're alerts-based so you don't need to remember to check.
Can I have different Notice of Correction text at each CRA?
Technically yes, but it creates confusion. Use the same wording at all three for consistency.
Will employers see the Notice of Correction?
Most employer background checks don't pull credit files unless the role is financial/regulated. If your role is in financial services or government, the Notice may appear on the background check report. Declare it proactively — it's a defensive marker, not a negative credit event.
I made a mistake on my Notice — can I edit it?
Yes. Email the CRA's customer service and request an edit. Replacement Notices process in the same 5-14 day window. You can also have them removed entirely.
Does the Notice of Correction apply to existing accounts or only new ones?
Only new applications. Existing accounts are unaffected — your existing credit cards, loans, and overdrafts continue working as normal. The Notice only triggers when a lender pulls your CRA file for a new credit decision.
Can a fraudster remove my Notice of Correction?
No. CRAs verify your identity before removing a Notice. The standard process is: write/email the CRA with the same verification documents you used to add it. CRAs are highly aware of the social-engineering risk and have multi-step identity verification on Notice removal.
Frequently asked questions
Can I freeze my credit file in the UK?
The UK doesn't have a true credit freeze like the US system. The closest equivalent is a Notice of Correction — a short statement placed alongside your credit report at each of the three UK credit reference agencies (Experian, Equifax, TransUnion). When a lender pulls your file, they see your statement and must apply manual review before approving credit. It's free at all three CRAs.
How much does a Notice of Correction cost in the UK?
Free at all three UK credit reference agencies — Experian, Equifax, and TransUnion. There's no fee, no recurring charge, and no expiration unless you remove it.
How long does a Notice of Correction last?
Indefinite. The marker stays until you ask the CRA to remove it. There's no annual renewal. For most fraud victims this means setting it once and forgetting it; for some it's worth removing after 2-3 years when the threat has passed and you have multiple credit applications coming up.
Does a Notice of Correction affect my credit score?
No. The Notice of Correction is just a text statement; it doesn't influence the credit-scoring algorithm. Lenders see it but it doesn't reduce your score. The downside is that lenders apply manual review on Notice-of-Correction files, so your own legitimate applications take longer (typically 1-5 working days instead of instant).
Do I need to put a Notice of Correction at all three CRAs?
Yes for comprehensive coverage. Different lenders use different CRAs. Some use just one; some use all three. A Notice at only Experian won't be seen by a lender who only checks Equifax. Applying at all three takes ~30 minutes total and gives full coverage.
What's the difference between Notice of Correction and CIFAS Protective Registration?
Notice of Correction is at the credit reference agencies (Experian/Equifax/TransUnion) and is seen during credit checks. CIFAS Protective Registration is at a different fraud-prevention database used by banks, telecoms, insurers, and other CIFAS members — often before they even pull a credit file. For comprehensive protection, do both: Notice of Correction at all three CRAs (free) plus CIFAS Protective Registration (£30 for 2 years).
