Common LEI Mistakes in United Kingdom

1 Mins Read

The LEI is simple — but a handful of avoidable mistakes catch out United Kingdom businesses every year. Here are the ones we see most.

The five most common mistakes

1. Letting the LEI lapse

The single most common error. A lapsed LEI is rejected at FCA-registered UK trade repositories and stalls onboarding. Annual renewal with reminders prevents it.

2. Registering the wrong legal entity

The LEI must match the exact legal entity on the Companies House record — not a trading name or a parent.

3. Not transferring an idle LEI

Holding an LEI with an unresponsive provider is risky. Transfers to TNV-LEI are free and the code never changes.

4. Treating share classes as separate

Share classes generally do not need their own LEI unless they are distinct legal entities.

5. Ignoring reference-data changes

A change of name, address or ownership must be reflected, or reconciliation breaks follow.

Key takeaways

• Renew on time.

• Register the exact legal entity.

• Transfer idle LEIs (it's free).

• Don't over-create LEIs for share classes.

• Keep reference data current.
