In 2018, the London Stock Exchange Group published its fifth annual '1000 Companies to Inspire Britain' report. It profiled 1000 privately held SMEs the exchange judged to be the UK's most dynamic and fastest-growing. The edition was publicly released, and LSEG continued publishing the series in subsequent years.
The report's purpose was to spotlight firms that rarely appear in mainstream business coverage but account for a large share of employment and turnover growth. Unlike the exchange's own listed companies, the 1000 profiled businesses had no obligation to disclose financial data publicly. The report gave them a platform to reach investors, policymakers, and potential customers.
To be included, companies generally had to show consistent sales growth over a multi-year period. The specific financial thresholds for 2018 were not detailed in the public materials. The broad criterion was sustained expansion rather than absolute size. The result was a list weighted toward businesses that had already demonstrated they could scale, not startups still searching for product-market fit.
Aggregate Scale of the 2018 Cohort
The 2018 cohort collectively generated significant total annual turnover and employed hundreds of thousands of people across the UK. These aggregate figures were intended to show that expanding SMEs are not a niche category. They contribute materially to the national economy.
The exact combined turnover figure for the cohort was not disclosed in the brief. Nor was the specific number of jobs. The publication's messaging emphasised collective weight rather than precise totals, consistent with how LSEG has handled the data in other editions.
What the document did make clear was that the 1000 companies operated across a wide range of industries and regions. They were not concentrated in London or in technology alone. The spread was deliberate: LSEG wanted to show that rapid growth was possible in manufacturing, professional services, construction, and consumer goods, sectors often overlooked in startup coverage.
Regional and Sectoral Distribution
Where the companies were based
The 2018 edition included a regional breakdown showing which parts of the UK produced the most fast-growing SMEs. The distribution favoured London and the South East. The report also highlighted strong representation from the Midlands, the North West, and Scotland. This geographic spread was presented as evidence that rapid expansion is not a London-only phenomenon.
Industries represented
Sectorally, the cohort spanned technology, manufacturing, professional services, and consumer goods. Technology firms were well represented, but the publication also featured a substantial number of industrial and engineering companies. LSEG's selection criteria did not favour any single sector. The list reflected the actual diversity of the UK's growing middle-market businesses.
The sector breakdown mattered for investors. A portfolio of expanding SMEs that includes manufacturers and professional services firms faces different risks than one concentrated in software. The report implicitly argued that the UK's strength lies in this breadth.
LSEG and Government Commentary
The launch event
The report was typically launched at an event with government support. Past editions had featured the Secretary of State for Business, and the 2018 edition was expected to follow a similar pattern. The brief did not specify which minister attended the launch, but the pattern of ministerial involvement underscored the policy relevance of the publication.
LSEG's perspective
LSEG leadership at the time emphasised the importance of SMEs to the UK economy. The exchange's executives noted that privately held expanding companies are often the source of future listed companies. This made the report a pipeline identification exercise as much as a celebration. The commentary framed the 1000 companies as businesses that could eventually seek a public listing on the London Stock Exchange.
Government figures who spoke at the launch typically stressed the need to support SME growth through regulation, access to finance, and skills policy. The document served as a tangible example of the kind of companies government policy was meant to encourage. The message: the UK already produces many high-growth businesses, and policy should aim to increase that number.
Significance for the UK Economy
Beyond the unicorns
The report's significance lay in shifting attention from a handful of high-profile unicorns to the broader base of growing privately held companies. In 2018, UK policy debates often focused on a small number of billion-dollar startups. The 1000 Companies publication argued that the real story was the thousands of smaller firms that collectively employ far more people.
It did not claim that the 1000 companies were the only expanding SMEs in the UK. It presented them as a representative sample, selected by LSEG's research team based on available data. The real value was in the aggregate: showing that hundreds of thousands of jobs and billions in sales come from companies that most people have never heard of.
Policy implications
For policymakers, the publication was a reminder that SME policy cannot be designed around a few visible companies. The diversity of sectors and regions meant that one-size-fits-all solutions would miss most of the target. The report implicitly supported tailored approaches to finance, regulation, and skills.
Promoting UK Companies to Investors
A curated list for investors
The report served as a marketing document for the UK as a destination for growth investment. By profiling 1000 companies across sectors and regions, LSEG gave domestic and international investors a curated list of businesses to research further. The document did not provide investment recommendations, but it signalled that these companies had passed a growth screen.
Visibility for the profiled companies
For the profiled companies, inclusion offered visibility that a privately held firm rarely gets. The report was covered by national and regional media, and it was distributed at the launch event to investors, policymakers, and business groups. A company that made the list could use the designation in its own marketing materials, though LSEG's rules around that usage were not detailed in the brief.
Part of LSEG's broader strategy
The publication also fed into LSEG's broader strategy of positioning itself as a partner for growth companies. The exchange operates markets for listed equities, bonds, and ETFs, but it also runs private company services. The 1000 Companies report was a way to build relationships with firms that might eventually list, while also demonstrating LSEG's reach into the private company universe.
Outcome and Legacy
What happened next
The 2018 report was published and the list of 1000 companies was made public. LSEG continued to publish the report annually in subsequent years, maintaining the same basic format. The publication did not lead to any single policy change or investment surge. It became a recurring reference point for anyone tracking UK high-growth private companies.
Limitations to note
The selection criteria were not fully transparent. The list depended on data that LSEG could obtain, which may have excluded companies that do not share financial information. The report was a snapshot, not a ranking. It did not track the performance of previous cohorts over time. A company that made the list in 2018 could have grown, stagnated, or failed, and the report would not reflect that.
For readers, the 2018 edition is one data point in a longer series. It shows which companies were growing in 2018, but it does not tell you which ones are still growing today. As of April 2024, the document's value is historical: it captures a moment when the London Stock Exchange Group tried to make the case that the UK's expanding SME sector was broader and deeper than the headlines suggested.
