Official statistics can tell you how many foreign-owned businesses sit in your region. They can’t tell you which ones they are.
For an inward investment team, that’s the bit that matters. You can’t book a retention visit with a statistic. You can’t invite an aggregate count to a sector roundtable, or put a percentage in front of a mayor as evidence that a Japanese automotive group is expanding its footprint in your area.
The Office for National Statistics (ONS) publishes authoritative figures on foreign direct investment and on foreign-owned businesses by region, industry, and country of ownership. They’re the right starting point for context, but they’re published in aggregate, at a broad regional level, and refreshed roughly once a year.
Regional teams need something more specific: a named list of every foreign-owned business operating in their patch, and who ultimately owns each one. Retention visits, targeted business support, a credible evidence base, and awareness of National Security and Investment Act 2021 considerations all depend on it.
This guide walks through how to build that list: the definitions to get right, the data sources available, a six-step framework, what to put in your report, and the pitfalls that catch most teams out.
Why identify foreign-owned companies in your region
Foreign-owned businesses are a small share of any region’s business base, but they carry far more weight than their numbers suggest. The recent ONS Annual Business Survey data shows that 1.4% of businesses in the UK non-financial business economy were foreign-owned in 2021, yet they generated 29% of its approximate gross value added (GVA). Knowing who they are underpins several core responsibilities for regional teams.
Inward investment retention and expansion
Foreign-owned employers are prime relationship targets. Their investment decisions are often made in a boardroom in Tokyo, Frankfurt, or Chicago, where your region is competing against sites in other countries as well as other UK regions.
A named list lets your team prioritise account management, spot expansion opportunities early, and hear about consolidation risks before a closure announcement lands. Aftercare is far easier when you know who you’re caring for.
Regional economic profile and evidence base
Economic strategies, Local Growth Plans, Local Plans, and funding bids all rely on an accurate view of the local business base. Foreign ownership shapes much of it, from supply chains and skills demand to the region’s exposure to global shocks.
Company-level data turns a single line in an evidence base (‘X% of employment is in foreign-owned businesses’) into something you can interrogate and defend.
Investment attraction
The foreign parent groups already present in your region are your warmest leads. A group that has had a good experience in one UK location is more likely to choose it again for a second site or an R&D centre.
Mapping ultimate parents also shows which source countries are already well represented, and where there are gaps worth targeting in your inward investment marketing.
Skills and employment intelligence
In many regions, a handful of foreign-owned employers dominate specific sectors, from automotive and aerospace to life sciences and financial services. Knowing who they are helps skills teams, colleges, and universities align provision with the employers that drive demand.
National Security and Investment Act 2021 awareness
The National Security and Investment Act 2021 gives the government powers to scrutinise acquisitions that could harm national security. Acquisitions of entities carrying out specified activities in 17 sensitive areas of the economy, including AI, defence, energy, and quantum technologies, must be notified and approved before completion.
Regional bodies don’t administer the regime, but they increasingly need to understand who owns the companies in their sensitive clusters, particularly where innovation funding, university spinouts, or public contracts are involved.
Post-Brexit ownership shift tracking
Since the UK left the European Union, the balance between EU and non-EU ownership has become a live policy question. Tracking whether your region’s foreign-owned base is shifting towards, say, US or Asian parents, and which companies are changing hands, needs company-level data. Annual totals won’t show it.
What ‘foreign-owned’ means
Before you build a list, you need a definition you can apply consistently. ‘Foreign-owned’ sounds simple, but a UK company’s immediate owner, its registered controllers, and its ultimate parent can sit in three different countries.
The ultimate parent test
The most useful definition for regional intelligence is based on the ultimate parent: the entity at the top of the ownership chain that controls the group and isn’t itself controlled by anyone else. If that entity is resident outside the UK, the company is foreign-owned.
This is important because multinationals rarely own UK subsidiaries directly. The ONS has shown that the United States, Ireland, and France all have higher ultimate than immediate foreign direct investment positions in the UK, meaning companies in those countries often control UK affiliates through holding companies elsewhere. Count by immediate owner and you’ll tend to overstate holding jurisdictions such as the Netherlands and Luxembourg, and understate the US.
Persons with Significant Control declarations and their limits
Since 2016, UK companies have had to declare their Persons with Significant Control (PSCs) to Companies House. A PSC is an individual or legal entity that meets one or more conditions, including holding more than 25% of shares or voting rights, or having the right to appoint or remove a majority of the board.
PSC data is the best public starting point for ownership analysis, but it was designed for transparency about control rather than for identifying the ultimate parent’s country. Where a company is owned by another company that keeps its own PSC register, it declares that company, not the entity at the top of the tree. For a primer, see our guide on how to check a company’s corporate structure.
Beneficial ownership versus registered ownership
Registered ownership is who appears on the share register. Beneficial ownership is who actually enjoys the economic benefit and control. They’re often the same, but trusts, nominee arrangements, and investment vehicles can separate the two.
For foreign ownership analysis, you care about control of the group, which usually means following corporate ownership up to the ultimate parent company rather than stopping at individual beneficial owners.
The intermediate UK holding company problem
This is one of the most common sources of error. Many foreign-owned UK operating companies are owned by a UK holding company, which is in turn owned by a foreign parent.
Look only at the operating company’s PSC entry and you’ll see a UK company as its controller, and classify it as domestically owned. The foreign parent may be one, two, or three layers further up, and every layer means another Companies House lookup.
Nominee shareholders and opacity
Nominee shareholders hold shares on behalf of someone else. They’re legitimate and common, particularly for listed and institutional investors, but they can obscure who’s really in control.
Opaque chains, such as those running through nominees, trusts, or jurisdictions with limited disclosure, are where ownership becomes hardest to read. They’re also where regional teams should be most careful before drawing conclusions.
ONS versus Companies House definitions
Official statistics and company registers don’t use the same lens:
- ONS foreign direct investment statistics follow international guidance and are presented on an immediate parent basis by default, with ultimate controlling parent analysis published separately.
- ONS business statistics, such as the Annual Business Survey, draw on the Inter-Departmental Business Register’s ownership markers and count businesses in aggregate.
- Companies House records legal entities and their declared PSCs, at the level of each individual company.
None of these is wrong; they answer different questions. Just be explicit about which definition you’re using, and don’t compare your own counts directly with ONS totals without explaining the difference.
The data sources for foreign-owned company identification
There’s no single public dataset that lists foreign-owned companies by region. Instead, you’ll be stitching together several sources, each with its own strengths and gaps.
Companies House PSC data
The PSC register is free, public, and available in bulk. For each company, it shows who has significant control, the nature of that control, and, for corporate PSCs, where that entity is registered.
Its limits are the ones we covered above: it stops at the first registrable entity, which is often a UK holding company, and it tells you nothing about where a company actually operates.
Confirmation statements and group structure filings
Confirmation statements record shareholder information, and annual accounts usually name the immediate and ultimate parent undertaking in the notes. That’s valuable, because it’s often the only place the ultimate parent is spelled out.
The catch is that it’s unstructured. Extracting parent names and countries from thousands of PDF accounts by hand isn’t realistic for most regional teams.
Register of Overseas Entities
The Register of Overseas Entities, held by Companies House, requires overseas entities that own UK land and property to identify their registrable beneficial owners.
It’s useful context for understanding foreign ownership of commercial property in your area. It’s a property register rather than a register of operating businesses, though, so it won’t identify foreign-owned employers on its own.
ONS aggregate statistics
The ONS publishes foreign-owned business counts, turnover, and approximate GVA by industry, size, and region through the Annual Business Survey, alongside its foreign direct investment bulletins.
These statistics provide useful context. A separate ONS experimental analysis, using a different method, found that just 1.1% of UK businesses were foreign-owned in 2018, yet they held 13% of total UK company assets. It also found that the North East had the highest proportion of its local units (individual business sites) under foreign ownership, at around 15%. The figures are aggregated, disclosure-controlled, and published with a lag, and they’ll never name a company.
Department for Business and Trade inward investment data
The Department for Business and Trade publishes annual inward investment results and case studies, and its regional teams work closely with local partners on specific projects.
This is valuable for tracking new projects and job creation, but it isn’t designed to be a complete inventory of every foreign-owned company already operating in a region.
Commercial company data platforms
Commercial platforms, including Beauhurst, join these public sources together. They link each entity in a corporate structure up to its ultimate parent and, with tools such as True Companies, consolidate a group’s legal entities into one profile. We cover how that works in practice at the end of this guide.
