In terms of Briars, we’ve spent 30+ years helping organisations with international expansion, with a particular strength on the U.S. – U.K. corridor. This transatlantic corridor makes up the majority of our work, and right now, we’re seeing more activity than at any point in the last decade.

​

What’s Behind the Momentum? A Game Changing Trade Deal

One of the biggest catalysts behind this surge is the UK–US trade agreement signed in May 2025. It’s not a full free trade agreement, but it’s shifting the landscape:

​

• Tariffs are down — especially across automotive, steel, agriculture, and raw materials

• Customs are faster — smoother processing is speeding up supply chains

• IP rules are clearer — helping tech and service businesses move with confidence

The bottom line? It’s cheaper, faster, and easier to do business across the Atlantic and those moving early are already seeing the upside.

​

What We’re Seeing Across the Atlantic

From LA to London, businesses are already adjusting their global strategies in response to the deal. Here are a few shifts we’ve observed:

 

1. Acceleration of U.K. Market Entry by U.S. Firms

Many U.S. businesses in SaaS, medtech, and advanced manufacturing had been holding back, waiting for clearer political and trade signals. With the trade agreement in place and administrations taking a pro-business stance, we’re seeing those hesitations fade fast.

 

2. Rebalancing of Supply Chains

Lower tariffs are prompting manufacturers to rethink sourcing. U.S. For example, U.S.-based logistics firms are now exploring British suppliers for electric vehicle components and aerospace tooling, sectors historically priced out by high tariffs.

3. Strategic Use of the U.K. as a European Gateway

Post-Brexit doubts are fading. With smoother access to U.S. markets and improving trade links to the EU, the U.K. is regaining its position as a launchpad into Europe  supported by cultural and legal familiarity U.S. founders value.

 

Where Risks Sit

The upside is real, but it still depends on how you move. Some common missteps we’re seeing:

​

• Delaying entry to wait for a full FTA — by then, your competitors may already have taken market share.

• Underestimating compliance complexity — faster customs processes don’t eliminate employment law, data protection, or tax obligations.

• Overlooking structural efficiency — the right entity, and support model can be the difference between fast traction and slow frustration.

 

Four Strategic Moves to Make Next

If you’re considering expansion or want to optimise existing transatlantic operations, here’s where to focus:

1. Reevaluate your supply chain
Reduced tariffs and faster clearance may shift the economics on sourcing and distribution.

 

2. Accelerate market entry
What used to take six months could now take three and being early matters.

 

3. Rework tax and compliance structures
Align with the new rules to avoid bottlenecks and maximise reliefs.

 

4. Use the UK as your European base
With simplified trade access, the U.K. is again a strong launchpad for U.S. firms into Europe.
