Correct LEI Data in the UK: Update or Challenge a Record

To correct LEI data in the UK, first establish whose record needs attention. Report changes to your own record to its managing LEI issuer; if you spot a suspected error in another entity’s record, use GLEIF’s Data Challenge Facility. The issuer updates the record only after verifying a change against an authoritative source.

What this means in the United Kingdom

For a UK company, the Companies House record can help you identify and explain a discrepancy. The GLEIF – Registration Authorities List assigns Companies House codes RA000585 for England and Wales, RA000586 for Northern Ireland and RA000587 for Scotland. An LEI record shows the relevant registration authority code and company number, giving you details to compare with the company register.

GLEIF’s linking identifiers to business registers initiative gives UK LEI records registered with Companies House a direct link to the company’s Companies House record. You can follow that link before submitting a Data Challenge. For example, a UK bank that spots an old registered office address in a client’s LEI record can compare the record with the company’s entry; a procurement team can use the same route while investigating a supplier whose LEI record lists the wrong parent company.

The Companies House – Find and update company information service also lets you search by company name or number. Treat the register as material to check, not an assurance that every filed detail is correct: Companies House says it does not check the accuracy of filed information. Check the filing history when assessing a discrepancy. If the underlying register information is wrong, challenging the LEI record alone will not fix the register.

How to correct LEI data: key points

• Your own details have changed: notify the issuer managing your LEI.
• Another entity’s record looks wrong: any LEI data user can raise a Data Challenge.
• One challenge covers one record, although it can identify several fields in that record.
• GLEIF says resolution typically aims to take ten business days; this is not a guaranteed deadline.
• After resolution, you have 28 days to rate the result or resubmit the challenge.

Choose between updating and challenging

GLEIF – Data Quality Management says a legal entity must tell its managing LEI issuer when its reference data changes. Annual renewal ensures, at a minimum, that the entity and issuer review and re-validate that data. If your company’s details need updating, contact the issuer about the change or renew your LEI and review its details at renewal.

For someone else’s record, use the GLEIF – Challenge LEI and vLEI Data facility to flag what you believe is incorrect. You may propose a replacement value, but you can instead explain why a field should change if you do not know the correct value. A challenge prompts a review; it does not change the published record on submission.

Before choosing a route, inspect the information currently shown. This guide to looking up an LEI and checking Companies House details can help you establish which record and field need attention.

Which information can you challenge?

GLEIF accepts doubts about the accuracy or completeness of reference data, the referential integrity between LEI records, possible duplicate entries and a lack of timely response to corporate actions. You can also challenge relationship data displayed in LEI Search, including direct and ultimate parent information and reporting exceptions. Identify the particular issue rather than asking for a general review.

The LEI code itself can be challenged on exclusivity or eligibility grounds. Exclusivity concerns an entity having more than one LEI; eligibility concerns whether a legal construct meets ISO 17442 criteria. These questions differ from correcting a reference-data field, so explain which concern you are raising.

Submit a GLEIF Data Challenge

GLEIF provides a User Guide on its challenge page. Prepare the disputed information and any supporting material before using the form:

1. Find the record and identify each field or issue you want reviewed. Submit a separate challenge for every additional record.
2. Propose new values where you know them. Otherwise, comment on why the existing information should change.
3. Add evidence as a file upload or text, such as a URL, explanation or reference. For a UK company, a Companies House record and its filing history may help explain your concern.
4. Review the submission. GLEIF automatically checks for data errors and contradictions, and you must complete a Captcha.
5. Submit it and retain the summary and email confirmation for reference.

Make clear what you dispute and why the material supports your concern. The managing issuer will update the record only after verifying a correction against an authoritative source, so evidence does not mean a proposed change will automatically be accepted.

What happens after you submit?

GLEIF immediately forwards the challenge to the issuer managing the LEI record and sends you a summary and confirmation by email. The issuer addresses the issue in dialogue with the legal entity and contacts you with the result. While the challenge is open, you can email the issuer.

In a blog published on 7 September 2026, GLEIF – After the Challenge: Rate, Resubmit, Improve describes an aim to resolve challenges typically within ten business days. It also describes options to rate a resolution or resubmit a challenge, available for 28 days after resolution. Neither the aim nor the option to resubmit guarantees that the issuer will make the requested change.

On resubmission, the previously challenged fields and proposed values are copied across. You add a comment and new evidence, while the original and resubmitted challenges remain linked.

Match the problem to the next step

What you find	Action
Your own entity’s reference data has changed	Tell your managing LEI issuer; review the data again at annual renewal.
Another entity’s record appears inaccurate	Submit a Data Challenge identifying the disputed information and providing evidence.
Several records need review	File one challenge for each record.
You disagree with a resolved challenge	Rate the result or resubmit with a comment and new evidence within 28 days.
You want another issuer to manage your LEI	Consider transferring your LEI to another issuer, a separate step from challenging data.

According to GLEIF – LEI-CDF 3.1 format, an LEI record identifies its responsible issuer in the ManagingLOU field and can show transfer statuses. A transfer changes who manages the LEI; it does not replace notifying an issuer about incorrect details. If the issue instead concerns a lapsed record, read the guide to lapsed LEIs and renewal.

Check the LEI record against the relevant source, then notify your issuer about changes to your own data or submit a separate Data Challenge for each other record you dispute.
