Document details contingency planning if Britain leaves the European Union in March with no transition deal.

The United Kingdom has published 25 so-called technical notices advising companies and people how to prepare for any disruption that might arise from a disorderly Brexit where there is no deal with the European Union.

Below are the highlights of what happens if the UK leaves the EU with no deal:

Trade

The free circulation of goods between the UK and EU will cease.

Companies trading with Europe would face new paperwork to cover customs and safety declarations.

Businesses would also have to apply the same customs and excise rules to goods moving between the UK and the EU as they currently apply when trading with a country outside the EU. Value Added Tax (VAT) could also have to be paid up front, potentially affecting cash flow.

Tariffs

Britain would introduce new, baseline import tariffs and rules-of-origin requirements for trade with World Trade Organization member countries. In a no-deal Brexit, they would apply to EU countries too.

The tariffs could differ from those the EU applies to imports from outside the bloc.

The paper reiterated that the UK intended to continue offering unilateral trade preferences to developing countries and would seek to replicate the EU’s free trade deals with countries around the world to avoid disruption for exporters.

Financial services

Britons will have to pay more to make card payments in the European Union and businesses on the continent could be cut off from investment banks in London.

In contingency planning for financial services, the government said it would take unilateral action on several fronts to minimise disruption.

State aid

The government will create a UK-wide subsidy control framework to ensure continuing control of anti-competitive subsidies.

Under the European Union (Withdrawal) act, EU state aid rules will be transposed into UK domestic legislation.

This will apply to all sectors and will mirror existing block exemptions as allowed under current rules, including the Agricultural Block Exemption Regulation, and the Fisheries Block Exemption Regulation.

The Competition and Markets Authority (CMA) will take on the role of enforcement and supervision for the whole of the UK.

Pharmaceuticals

The UK will have its own system to regulate human drugs and medical devices.

Companies will have to submit regulatory information on drugs, medical devices and e-cigarettes directly to the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA).

UK will continue to accept batch testing of medicines carried out in EU countries.

EU blood directives will no longer apply to the UK. The government is working to ensure blood safety and quality from day one.
