Brexit: What You Need to Know

The decision to leave the European Union has the potential to have the largest impact for the UK’s legal system, its economy and, its population for many years or even decades.

Herrington Carmichael’s legal team stands ready to offer advice, guidance and support to you, your family and business so you can be prepared for the expiry of the transition period on 31 December 2020.

Commercially Prepared?

Whether it is advice on contractual rights, obligations or you want to know if your contract will be affected or whether you need legal support in respect of immigration matters, data protection or legal aspects in relation to supply chains, we can help.

Under the Withdrawal Agreement, the UK continues in most respects to be treated as if it were still part of the EU. The Withdrawal Agreement provided a mechanism to extend this period but it has not been used and it therefore seems that the full legal impact of Brexit will only really be felt by UK businesses from 1 January 2021.

Our experts are continuously analysing the full range of Brexit-related risks and opportunities facing businesses and developing legal strategies to manage them effectively. Working in conjunction with our clients, our team offers strategic and practical advice to help plan and shape an effective response to Brexit.

How will Brexit affect your business?

Brexit threatens to have a significant impact on all UK businesses when they are importing and exporting goods and services from suppliers in the EU, as well as EU businesses when they are exporting goods and services to the UK. As such, all businesses (particularly manufacturers and retailers) need to consider the impact of Brexit both as a buyer of goods (whether as finished goods or components that are used to manufacture goods in the EU) and services from suppliers in the EU and when they are selling goods and services to customers in the EU. Therefore, whatever the size of your business, there is an essential need to understand how Brexit will affect your business.

Not only this, but any commercial contract which takes effect across the EU and UK may be materially impacted by Brexit. Given that the transition period from the UK’s exit from the European Union ends on 31 December 2020, with or without a deal, whilst time is running out, now is the time to take action. Therefore, to the extent not already considered, each business should consider how Brexit will affect each contract, whether the business is importing or exporting.

What are the key considerations?
How Brexit affects business will vary across the board but every organisation faces challenges when it come to leaving the EU which we all need to address. Our team have provided some practical steps you can take now to help your business prepare for life after Brexit.

References to “EU” as a territory
If a contract refers to the EU (for example, by establishing the EU as an area of exclusivity or by stating that a distributor has selling rights in the EU), the UK’s exit from the EU could lead to unintended treatment of the UK under that contract. For instance, that area of exclusivity may be cut down so that it no longer covers the UK which may be contrary to the parties’ intentions. Businesses should therefore ensure that contracts clearly address territorial scope. If territory is defined in existing agreements by reference to the EU or EEA, then this may need to be reviewed and updated (for example, in agency, distribution and franchise agreements, intellectual property licences and non-compete clauses). To avoid the UK being carved out post Brexit, businesses should clearly define the territorial scope by reference to membership of the EU at the date the agreement was signed or by express reference to the UK, if it is intended that the UK would fall within the definition moving forward. This may require a formal variation to the contract.

Supply chain
The import of goods from the EU to the UK and the export of goods from the UK to the EU will require the correct completion of customs procedures. If you trade within the EU, review your contracts and start to prepare contingency plans for export controls on the sales of goods and services to EU countries as it is quite likely that existing contracts between UK and EU businesses will not deal with who needs to do what and the liabilities that will arise out of non-compliance. Businesses will also now need an Economic Operator Registration and Identification number in order to move goods between the UK and the EU – so apply now.

Certain tariffs could be applied to goods and services provided to and from the EU following the end of the transition period and businesses should therefore consider (amongst other things) which party is going to absorb the costs of those tariffs under their contracts, how those tariffs will be calculated and whether anything can be done to reduce those tariff costs. If tariffs are applied, this could result in businesses looking to purchase goods and services in their country of origin in order to avoid these tariffs.

Suppliers should be careful when quoting customers in order to factor in the extra costs of the tariffs as if they are intending to pass those increased costs on to the customer, it may be prudent to make this clear in the quote.

In addition, existing contracts will need to be reviewed to ascertain who bears the costs of any change in tariffs as this may have an impact on the approach taken by many businesses.

Exchange rates
It is expected that there could be further changes in exchange rates such as those that were seen immediately following the result of the referendum back in June 2016, when the pound fell sharply against the dollar and the euro. As a result, businesses should consider whether they are contractually protected or at risk from exchange rate fluctuations in their contracts or whether they need to address this in their contracts or whether they need to address this in contracts moving forward. Businesses should be reviewing their commercial contracts generally to see what their position is, and which party absorbs the costs in relation to exchange rate fluctuations.

When the UK ceases to be part of a customs union with the EU, customs checks will be needed for goods entering and leaving the EU. Businesses therefore need to consider the commercial impact of the delay including what the liability may be (if you suffer the delay) and what your remedies may be if your supplier is late. Particular consideration needs to be given to;

• whether time is of the essence?
• Whether liquidated damages/service credits are payable as a result of such delay?
• What liabilities arise?
• What termination rights apply as a result of the delay?

Data Protection
Data protection arrangements, and in particular transfers of personal data from EEA states to the UK, are perceived as one of the more immediate issues that need to be addressed before the end of the transition period. For more information on the implication of Brexit in relation to data protection, please see our data protection article.

Further contractual considerations
There are a number of practical measures which businesses should undertake such as:

Contractual terminology: Any references to EU bodies, laws and regulations may need to be updated after Brexit so they are corrected to the relevant national references.

Termination: Businesses should review their contracts to see to what extent suppliers or customers are able to terminate contracts as a result of Brexit. The timing of Brexit is relevant to this analysis. If the contract is likely to expire before 31 December 2020, no changes may be necessary or the expiry date will at least provide the appropriate opportunity for any renegotiation to take place.

Framework agreements: If suppliers have the right to reject orders, they may exercise this right as a result of Brexit to avoid the negative affect that Brexit may have on their business such as foreseeable delays at customs and increases in tariffs. Customers should avoid this scenario by drafting their contracts in a way which prohibits the supplier from having this right or by requiring the supplier to fulfil a minimum amount of orders each year under the contract.
