After leaving the EU the role of policing and ensuring fair competition in UK markets (including state aid) will fully transfer to British regulators and agencies. This could result in differences to the current approach – for instance on approvals for mergers and acquisitions.

The Competition and Markets Authority (CMA) has published a notice on its role after Brexit.
CMA's role after Brexit

And another for the specific case of a ‘no-deal’ exit from the EU.
Effects of a 'no deal' EU Exit on the functions of the CMA

If there is no Brexit withdrawal agreement before March 2019, the government has developed a ‘no deal’ competition Statutory Instrument (SI):

Mergers: If the European Commission has issued a decision on or before the day the UK leaves the EU (unless the decision is annulled, in full or in part, following an appeal), the UK has no jurisdiction. UK-EU mergers will now occur via private contracts, not through the EU regime. Seek legal advice on individual ongoing merger cases.

State aid: The government is expected to pass secondary legislation which will transpose EU state aid rules into UK law and provide for the CMA to take on its new state aid role, following which they will publish further details on how this function will operate.

Antitrust: After the UK’s exit from the EU, the CMA will no longer have jurisdiction to apply anti-competitive agreements including cartels or on abuse of dominance.

The CMA published a consultation on their functions, relating to mergers, antitrust and consumer protection processes, in a no deal scenario: CMA Consultation:

Data protection, GDPR, and mobile roaming

Your business may be affected by changes to regulations on personal data transfers and mobile roaming.

  • In the event of a no deal, the Department for Digital, Culture, Media & Sport do not expect the European Commission to have made adequacy decisions regarding the UK at the point of exit. Therefore, in order to continue the legal transfer of personal data from the EEA to the UK, alternative transfer mechanisms will need to be in place.
  • Rules governing the transfer of personal data from the EEA to the UK will require businesses to obtain additional safeguards (such as standard contractual clauses)
  • Rules governing the transfer of personal data from the UK to the EEA will remain similar to the existing status quo
  • UK businesses providing goods or services or tracking customer behaviour in EU/EEA without an established presence in an EU member state may need to appoint a European representative
  • UK businesses processing personal data across borders may need to find a lead supervisory authority in the EEA
  • Surcharge-free mobile roaming when travelling to the EU is no longer guaranteed
  • Traders from UK, EU and 3rd countries can offer different terms to UK customers compared to EU customers

The Government have published guidance for using personal data after Brexit:

The Information Commissioner’s Office (ICO) has published a checklist of six steps that businesses can take now to start preparing for data protection compliance if the UK leaves the EU without a deal:
