UK export controls explained: the Strategic Export Control Lists, ECJU licences and the SPIRE-to-LITE switch

Britain runs its own list, its own licence types and — since Brexit — two legal regimes on one island: Great Britain under assimilated EU law, Northern Ireland still under Regulation 2021/821. Here is the system an exporter actually meets: the consolidated list, SIEL against OIEL against OGEL, and a licensing platform mid-migration.

Questions, answered straight.

What is the UK Strategic Export Control List?

The consolidated list of everything the UK controls for export: the Military List (ML1 to ML22), UK-specific entries such as PL9013, and the dual-use list in five-character format.

What is the difference between SIEL, OIEL and OGEL?

A SIEL licenses one named shipment; an OIEL licenses a defined flow of your products over time; an OGEL is a pre-published general licence anyone can use after registration, if every condition fits.

Do exports from Great Britain to the EU need a licence?

For controlled dual-use items, yes — the EU stopped being licence-free at Brexit. The consolidated Dual-Use OGEL covers much of that trade for registered users who meet its conditions.

What is LITE?

ECJU's new licensing platform, replacing SPIRE. It has processed SIELs in public beta since September 2024; OIELs are in private beta, and OGEL registration still runs on SPIRE as of November 2026.

Why is Northern Ireland different?

Under the Windsor Framework, Northern Ireland continues to apply the EU's Regulation 2021/821 for dual-use exports, while Great Britain applies the assimilated Regulation 428/2009.

How long does an ECJU licence take?

ECJU's published target is 70 per cent of SIELs within 20 working days and 99 per cent within 60; its quarterly statistics show actual performance, which in 2025 sat near half within 20 days.
