How does the 2026 UK/EU Treaty align Gibraltar with EU state aid law under Article 201 and Annex 18?

Short answer

The 2026 UK/EU Treaty effectively extends the EU’s substantive state aid framework to Gibraltar. Article 201, read with Annex 18, requires Gibraltar to apply core EU Treaty provisions, block exemptions and Commission guidelines when assessing aid that affects EU–Gibraltar trade or investment, substantially aligning Gibraltar’s regime with that of EU Member States.

Detailed answer

Annex 18 incorporates key EU state aid provisions, including:

• Articles 93, 106, 107, 108 and 109 TFEU
• procedural rules
• block exemption regulations
• detailed compatibility guidelines

Gibraltar’s independent authority must apply these instruments in the same manner as the European Commission, with limited recognition that some EU acts may not be immediately relevant given Gibraltar’s specific economic profile.

Dynamic alignment

Under Article 19, where the EU amends the EU laws the Agreement requires Gibraltar to apply, or adopts new related laws, those changes must also be given effect in Gibraltar. If Gibraltar does not apply a relevant EU act, the whole Agreement terminates unless the Cooperation Council decides otherwise.

Status: the Agreement has been provisionally applied since 15 July 2026, pending formal ratification.
