When someone dies, their credit file does not close on its own. You have to notify Experian, Equifax and TransUnion, and until you do the file stays live — which is exactly the gap that impersonation fraud looks for. Adding a deceased marker to a credit file is the single administrative step that shuts that door, and none of the three agencies charges for it.
It matters for a reason that is easy to miss in the first weeks. Fraud against people who have recently died is a recognised pattern. The name and dates are often published in a death notice, the address may be standing empty, and a lender running a check has no way of knowing the applicant is not alive unless the file tells it so. The marker is what tells it. Once the flag is on the record, an application for credit in that name is stopped, and most credit marketing to the address dries up too.
There is a second job the marker does, and this one matters to you rather than to the estate. If you held anything jointly with the person who died — a mortgage, a loan, a joint current account — your own credit file is financially linked to theirs, and that link does not break by itself. Dealing with the marker and the association together is what stops a closed chapter surfacing on your own credit applications for years afterwards.
At a glance
- Experian, Equifax and TransUnion hold separate files. A marker added to one does not appear on the other two, so you notify all three.
- A deceased marker is free. It blocks new credit being taken out in the name and cuts off most marketing to the address.
- Tell Us Once and the bank you inform do not reliably reach the credit reference agencies. Assume it is a job you have to do yourself.
- If you shared any account, ask each agency to break the financial association once the joint account is closed or moved into one name.
- Check your own file a few weeks later to confirm the link has actually gone, because it does not always drop off first time.
The short answer: notify all three, in writing
There is no single switch. The three UK credit reference agencies are separate companies with separate databases, and a death recorded at one is invisible to the other two. So the task is to contact each of Experian, Equifax and TransUnion, give them the death certificate details and the addresses the person used, and ask for a deceased marker to be applied to the file.
Each agency has a dedicated bereavement route — an online form or a postal address — rather than the general customer line, and using the right one saves a great deal of time. Some third-party bereavement services will pass a notification to more than one agency at once, but before you rely on any of them, check exactly which agencies it reaches. A service that covers two of the three still leaves a live file at the third.
Do it in writing wherever you can, and keep a copy. You are not only recording a death; you may later need to prove when you told them, particularly if fraudulent credit is attempted in the window before the flag went on.
What a deceased marker actually does
The marker is a flag on the credit file that says the person has died. Its practical effect is threefold. First, any lender that runs a credit check against that name and date of birth sees the flag and declines the application — which is the mechanism that blocks the commonest form of post-death impersonation. Second, it removes the file from most of the marketing and pre-approval lists that generate unsolicited credit offers, so the pile of "you're pre-approved" letters landing at the address slows and stops. Third, it gives the lenders who already hold accounts a consistent signal to close them down.
What the marker does not do is close the accounts for you or settle anything owed. Those are separate jobs handled with each lender directly. Nor does it, on its own, stop money already leaving the account — a card being used after death is a different problem, and if you suspect someone is still spending, read our guide on whether it is illegal to keep using a dead person's bank card. The marker is a preventive shield against new borrowing, not a clean-up of everything that already exists.
How to notify Experian, Equifax and TransUnion
Work through them one at a time and treat each as a fresh notification. In every case you will be asked for the full name of the person who died, their date of birth, their date of death, and the addresses they have lived at — the agencies match on address history, so a former address left out can leave part of the record unmatched.
You will normally also need to send, or upload, a copy of the death certificate. An interim certificate issued while a death is still being investigated is usually accepted for this purpose; you do not have to wait for the final document. Keep the original safe and send copies, because you will be sending the same evidence to a long list of organisations over the coming months.
Ask each agency to confirm in writing once the marker is applied. Confirmation matters because it is your evidence that the file was flagged, and it is the point from which you can reasonably expect new applications in that name to fail. If a letter still arrives weeks later offering credit, that confirmation is what you quote back to them.
Tell Us Once and the bank will not do this for you
It is a fair assumption that reporting a death once — through the register office, or to the deceased's bank — cascades everywhere. It does not. The government's Tell Us Once service is genuinely useful, but it notifies government departments such as HMRC, the DWP and the DVLA, not the private credit reference agencies. There is a long list of bodies it never contacts, which we have set out separately in what Tell Us Once does not cover. The credit agencies are firmly on that list.
The banks are a partial exception. Several major lenders feed a shared death-notification arrangement that updates other banks, and some pass information to the agencies, but coverage is patchy and you cannot rely on it having happened. Treat the credit-file marker as a job you own until you have written confirmation that it is done. Assuming someone else has handled it is precisely how a file stays live for months.
Checking your own file and breaking the financial association
This is the part that protects you rather than the estate, and it is the part people most often skip. When two people hold a joint account, or one acts as a financial guarantor for the other, the credit agencies create a financial association between the two files. From then on, a lender assessing one person can take the other's credit history into account. That is harmless while both are alive and sharing finances. After a death it can quietly work against the survivor.
Closing the joint account, or moving it into your sole name, does not automatically sever the association. You have to ask each agency specifically to remove the financial link, a step sometimes called a notice of disassociation. Until you do, the record of the person who died can still be pulled into an assessment when you apply for a mortgage, a card or a loan of your own. If your late partner had ever managed the same authority under a lasting power of attorney, note that any authority held under a power of attorney ends at death too, which is a related reason to make sure every shared arrangement is formally unwound.
A few weeks after asking, check your own credit file with each agency to confirm the association has actually dropped off. You are entitled to see your statutory credit report, and the association either appears on it or it does not. It is not unusual for a disassociation to fail the first time and need chasing, which is exactly why you check rather than assume.
Tracking down the accounts before you close them
Before the marker can do its full job, you need to know what credit and what accounts existed, and that is rarely tidy. Statements, letters and the annual notices lenders send are the obvious trail. A copy of the person's own credit report, which the executor can usually request with proof of death, is the most complete single view of the accounts held in their name — useful both for closing them and for spotting anything unfamiliar that might already be fraudulent.
Where the paperwork has gone missing entirely, families sometimes wonder whether to pay for a commercial search of lost accounts and policies. That can be worth doing in the right circumstances, but there are free routes to exhaust first, and we weigh the paid option honestly in our look at whether an unclaimed assets search is worth paying for. The credit report and twelve months of bank statements usually reveal more than any database.
Scotland and Northern Ireland
The credit reference agencies operate UK-wide, so the process of adding a deceased marker and breaking a financial association is the same wherever in the United Kingdom the person lived. What differs around the edges is the surrounding administration rather than the credit file itself.
In Scotland the grant that gives an executor authority is called confirmation rather than probate, and the register office paperwork differs; in Northern Ireland the notification services and some of the government routes work differently again, so the assumption that one report cascades everywhere is even riskier there. None of this changes what you ask the three agencies to do. The wider order of tasks after a death is set out in our guide to bereavement admin, assets and contracts, which links the credit-file step to the account closures around it.
Where life cover fits in
Notifying the credit agencies is defensive housekeeping — it protects a name and a survivor's own record from the consequences of a death that has already happened. The reason a joint mortgage or a shared loan becomes such a heavy part of this admin is that the debt does not die with the borrower, and a survivor can be left carrying it alone.
That is the gap life cover is designed to close. A policy written to clear a mortgage or an outstanding loan pays out to settle the debt at the moment it would otherwise land on the person left behind, which is the difference between breaking a financial association on a cleared account and being tied to one you cannot afford. Whether an insurer offers cover, and on what terms, depends on underwriting rather than on anything a website can promise, so if this has prompted you to check your own arrangements, you can get life insurance quotes priced against your actual debts by an FCA-authorised broker.
Frequently asked questions
Do I have to tell all three credit reference agencies?
Yes, unless you use a service that notifies them together and you have confirmed it reaches all three. Experian, Equifax and TransUnion hold separate files, and a marker added to one does not appear on the others. Each has its own bereavement form and will ask for the death certificate details and the addresses of the person who died before applying the flag.
What does a deceased marker actually do?
It flags the file so that any lender checking an application in that name can see the person has died, which blocks the commonest form of impersonation fraud. It also stops most credit marketing arriving at the address and gives the lenders who hold existing accounts a consistent signal to close them down. It does not settle debts or close accounts by itself.
How do I remove the financial link to my late husband?
Ask each agency to break the financial association once the joint accounts are closed or moved into one name. Until that is done, his record can still be taken into account when you apply for credit yourself. Check your own file a few weeks afterwards to confirm the association has actually gone, because it does not always drop off at the first attempt.
