Country Desk Brief
Legal System, Investment, Trade & Regulation
A common-law jurisdiction (England & Wales) centred on case law and strong freedom of contract — a system that has become the preferred governing law for a large proportion of international commercial contracts and financing documentation globally. Scotland operates under a mixed legal system. Since Brexit, the UK has developed its own distinct regulatory framework, separate from EU law. Mermeroglu Legal advises on market entry, investment structuring, foreign trade and dispute resolution in the UK, working in coordination with our London partner office across cross-border M&A, finance and LCIA arbitration proceedings.
The most common entry vehicle for foreign investors is the private limited company (Ltd) — incorporated through Companies House quickly and largely online. The PLC is used for publicly listed structures. Branches (registered as UK establishments) and direct acquisition of existing businesses are also common foreign-entry routes.
The UK actively promotes inbound FDI and imposes virtually no nationality restrictions on ownership or management. However, the National Security and Investment Act 2021 (NSIA) requires mandatory notification — and in some cases approval — for transactions in designated sensitive sectors. The predictability of English law, London's status as a global financial centre, and the choice of LCIA arbitration make the UK a primary hub for international cross-border transactions.

Investment & Trade Indicators
Establishment
How to Form a Company
The private limited company (Ltd) is the standard vehicle — incorporated through Companies House, typically online within 24 hours. No minimum share capital is required in law; no residency requirement for directors or shareholders. The PLC is used for publicly listed companies (minimum allotted capital £50,000). Branches (registered as UK establishments) are also a common route for foreign companies.
Foreign ownership: the UK actively promotes inbound FDI with virtually no nationality-based restrictions. However, transactions in designated sensitive sectors under the National Security and Investment Act 2021 (NSIA) require mandatory notification to the Investment Security Unit (ISU) and, in some cases, approval before completion. Many transactions have been reviewed; very few have been prohibited.
Sensitive sectors under NSIA: currently 17 designated sectors including advanced materials, AI, civil nuclear, communications, data infrastructure, defense, energy, military and dual-use, satellite and space, and suppliers to the emergency services. The government is considering adding critical minerals, semiconductors and water.

Investment Climate
Investment Models & Where Capital is Flowing
The UK ranked second in Europe for FDI projects in 2024 (985 projects, EY Barometer), behind France. FDI volumes fluctuate year to year; financial services, technology, life sciences and green energy are the principal sectors of attraction. London's unique position as a global financial centre, the predictability of English law, and the availability of LCIA arbitration as a dispute-resolution mechanism are persistent structural advantages.
- Financial services — London remains the world's leading financial centre by most measures; banking, insurance, asset management, fintech and capital markets are principal FDI sectors.
- Technology & software — the UK's tech sector is the largest in Europe; London is consistently ranked among the top global tech investment hubs.
- Life sciences & pharmaceuticals — a historic strength reinforced by post-pandemic investment; Oxford-Cambridge Arc is a growing cluster.
- Green energy — offshore wind, green hydrogen, carbon capture and battery storage are active investment themes; the UK has the largest offshore wind capacity in the world.
- Legal & contractual framework — the predictability of English law, London arbitration (LCIA) and the English courts' established body of commercial case law make the UK the preferred seat for cross-border transactions globally.
- Post-Brexit regulatory autonomy — the UK now operates its own financial services, competition and data protection regimes, creating both complexity and opportunity for structuring.
Foreign Trade — 2024
Recent Trade & Principal Partners
The UK's total goods and services exports were approximately £873 billion in 2024. Services exports — particularly financial services — account for roughly half of total exports, a structural feature that distinguishes the UK from most major trading nations. There is a persistent structural goods deficit (imports exceeded goods exports by approximately £42 billion in 2024). The EU remains the UK's largest trading bloc (~42% of exports, ~52% of imports). The USA is the single largest trading partner for both goods exports and services trade in both directions.

Regulatory Developments
Notable Legislative Changes
In force 1 August 2025
Arbitration — Arbitration Act 2025
The most significant reform of UK arbitration law since the Arbitration Act 1996. Key changes: clarified emergency arbitrator powers; summary disposal of unmeritorious claims; strengthened arbitrator disclosure duties and immunity; streamlined jurisdictional objection procedures; and — unless parties agree otherwise — the arbitration agreement is now governed by the law of the seat. LCIA Rules 2020 remain operative.
In force 4 January 2022
Investment Screening — National Security and Investment Act 2021
Introduced powers to review and, where necessary, block or impose conditions on transactions in 17 designated sensitive sectors on national security grounds. Mandatory notification is required for qualifying acquisitions in those sectors before completion. The government is actively considering expanding the list of sensitive sectors.
Enacted May 2024
Competition & Digital — Digital Markets, Competition and Consumers Act 2024
Established the UK's new digital markets regulatory regime, operationalising the Digital Markets Unit (DMU) within the CMA. Designates platforms with "strategic market status" and gives the CMA powers to impose conduct requirements, pro-competition interventions and enforcement actions.
Ongoing — post-Brexit regulatory divergence
Financial Services — Own Regulatory Framework
Following Brexit, the UK Financial Services and Markets Act 2023 transferred EU-derived financial services law into UK law and gave the FCA and PRA broad powers to revise and replace inherited EU rules. Energy, construction and banking are regulated primarily through sectoral regulators (Ofgem, FCA/PRA) and ongoing regulatory updates rather than single landmark primary legislation.
Note: energy, construction and banking in the UK are governed primarily by sectoral regulators (Ofgem, FCA/PRA) and evolving regulatory guidance rather than single landmark statutory changes. Project-specific verification against current official sources is recommended.
Our Approach
How Mermeroglu Legal Engages in the United Kingdom
UK mandates typically combine Ltd or PLC structuring with NSIA screening advice for sensitive-sector acquisitions, and frequently engage English law as the governing law for financing documentation and dispute resolution. Our practice is structured to coordinate across those systems through a single point of accountability, working in close coordination with our London partner office.
Each mandate is led by a single matter principal at the firm, supported by an internal team and local counsel — covering company formation, investment screening under NSIA, financing, foreign trade, M&A and dispute resolution before the LCIA and English courts.
