1. Council Directive 2010/24/EU(1) shall apply until 5 years after the end of the transition period between the Member States and the United Kingdom in respect of claims relating to amounts that became due before the end of the transition period, claims relating to transactions that took place before the end of the transition period but where the amounts became due after that period, and claims relating to transactions covered by Article 51(1) of this Agreement or movements of excise goods covered by Article 52 of this Agreement.

2. By way of derogation from Article 8, the United Kingdom shall have access, to the extent strictly necessary to exercise its rights and comply with obligations under this Article, to the networks, information systems and databases listed in Annex IV. The United Kingdom shall reimburse the Union for the actual costs incurred by the Union as a consequence of facilitating that access. The Union shall communicate to the United Kingdom the amount of those costs by 31 March of each year until the end of the period referred to in Annex IV. In the event that the communicated amount of the actual costs incurred considerably diverges from the best estimates amount that was communicated by the Union to the United Kingdom before the signature of this Agreement, the United Kingdom shall pay without delay to the Union the best estimates amount and the Joint Committee shall determine the manner in which the difference between the actual costs incurred and the best estimates amount is to be addressed.
