The UK Government has agreed with the European Union a deferral of the UK’s exit date until no later than October 31, 2019. If the UK Parliament ratifies the Government’s withdrawal agreement with the EU before October 31, the UK’s exit will take place on the first day of the month following ratification. Until exit takes place, the UK remains a member of the European Aviation Safety Agency system and existing regulatory arrangements continue to apply. The CAA will provide further updates as necessary.

On 7 June 2018, the Government published a series of slides on the 'Framework for the future UK-EU partnership' for transport, in which it sets out its desire to secure liberal aviation market access arrangements. The slides also reaffirmed the desire, first set out by the Prime Minister in her Mansion House speech in March, to explore the terms of participation in the European Aviation Safety Agency (EASA).

Determining the future relationship is a matter for the UK Government in its negotiations with the EU. The CAA welcomes the ambition for aviation - including exploring participation in EASA - set out on 7 June 2018. The CAA understands that the aviation industry and its consumers want as much clarity as possible with respect to the UK's future relationship with the EU.

A key feature of the EASA safety system is mutual recognition of licences, certificates and approvals among participating member states. Aviation is inherently an internationally integrated industry. This is reflected in regulatory arrangements for personnel such as pilots and engineers, and support operations such as design, maintenance and spare parts production. We believe that if the UK Government and CAA’s preferred outcome of ongoing EASA membership proves not possible, then a continuation of mutual recognition, at least for a time-limited period, would strongly be in the interests of consumers and the aviation industry both in the UK and the rest of Europe. 

We are providing information on this microsite to enable aviation businesses and organisations to make their own decisions on how to prepare for a range of scenarios, regardless of their likelihood. This includes a scenario where there is a non-negotiated withdrawal. 

Preparing for a non-negotiated withdrawal

As a responsible regulator, we need to prepare for the possibility that no agreement is reached between the UK and the EU. We have been undertaking this work for some time to ensure there is maximum continuity and stability for travelling passengers and the aviation and aerospace sectors should a no-deal scenario occur.

On 24 September 2018, the UK Government published technical notices that outline in detail the implications of a non-negotiated withdrawal from the EU on the aviation and aerospace industries. These covered aviation safety, aviation security and air services. We urge our stakeholders to read these technical notices and consider as soon as possible what action they might need to take to maintain continuity and stability of aviation services they provide. 

On 7 March 2019, the Government published a further technical notice setting out the UK’s position on reciprocity of rights for airlines from EU countries. This document, which is the UK’s response to the measures contained in the EU’s no-deal air connectivity regulation, provides further information about the basis on which flights will continue between UK and EU in the event of ‘no deal’.

The purpose of this microsite

The CAA has developed this microsite to be a central source of information for the aviation and aerospace industries about the actions they would need to take to be prepared for a no deal withdrawal from the EU and no continued mutual recognition. Where a specific action is required, this is underlined.  

The content of this microsite is based on the information set out in the Government’s technical notices, and is subject to current understanding about the Government’s policy and how it would incorporate the EU aviation body of law into UK law under the Withdrawal Act.  Any changes to the Government’s policy or legal framework could lead to changes to the information contained on this website. 

The CAA has also created this short introduction to what a non-negotiated withdrawal means for aviation safety regulation.

This microsite will be updated frequently with new information for our stakeholders. We urge you to keep abreast of relevant updates. To be alerted to significant new information, please subscribe to the EU exit category in our SkyWise alerting system:


This microsite is aimed at individuals in the aviation and aerospace industries. The Government and the CAA are working closely with the industry to seek to maximise continuity and stability for aviation in the event that no deal can be agreed between the UK and the EU. Our aim is for consumers to notice as little impact as possible on their air travel arrangements once the UK has formally withdrawn from the EU.
