UK business statistics provide a useful picture of the size, structure, performance, and regional distribution of businesses across the country. They can help entrepreneurs, investors, researchers, marketers, policymakers, and business owners understand where economic activity is concentrated and how the business landscape is changing.
The latest official figures show a large and diverse business population. Millions of small businesses operate alongside medium-sized and large companies, while industries such as construction, professional services, wholesale and retail continue to represent significant parts of the economy.
It is important to understand that different official datasets measure different things. The Department for Business and Trade’s Business Population Estimates focus on the estimated total private-sector business population, while ONS datasets can focus on VAT- and/or PAYE-registered businesses or enterprise demography.
This guide brings together the most useful UK business statistics and explains what they mean.
How Many Businesses Are There in the UK?
According to the latest Business Population Estimates, there were approximately 5.69 million private-sector businesses in the UK at the start of 2025. The business population increased by about 191,000 businesses, or 3.5%, compared with 2024.
However, this figure should not be confused with the number of VAT- and/or PAYE-registered businesses.
ONS reported approximately 2.735 million VAT- and/or PAYE-based businesses in 2025. These figures cover a narrower population than the Business Population Estimates because they do not attempt to include the entire private-sector business population.
Why Are the Numbers Different?
The difference exists because official datasets use different definitions and sources.
The Business Population Estimates include businesses that may not have employees or may not be registered for VAT or PAYE. In 2025, approximately 4.27 million businesses had no employees, representing around three-quarters of the estimated private-sector business population.
Therefore, when quoting a UK business statistic, it is important to state which dataset and definition you are using.
UK Business Statistics by Size
The UK business population is dominated by small businesses.
| Business size | Number of businesses | Share of private-sector businesses |
|---|---|---|
| Small: 0–49 employees | 5.64 million | 99.18% |
| Medium: 50–249 employees | 38,435 | 0.67% |
| Large: 250+ employees | 8,335 | 0.15% |
| All businesses | 5.69 million | 100% |

Small businesses therefore make up almost the entire UK business population. Medium-sized and large businesses represent a much smaller number of companies but make an important contribution to employment and turnover.
SMEs and Their Economic Contribution
Small and medium-sized enterprises, commonly called SMEs, are central to the UK economy.
At the beginning of 2025:
- There were approximately 5.68 million SMEs.
- SMEs represented 99.85% of the UK private-sector business population.
- SMEs employed approximately 16.9 million people.
- SMEs accounted for around 60% of private-sector employment.
- SME turnover was estimated at approximately £2.8 trillion, around 51% of the total private-sector turnover covered by the estimates.
These statistics demonstrate why changes affecting smaller businesses can have a substantial impact on the wider UK economy.
Small Businesses
Businesses with fewer than 50 employees accounted for approximately 5.64 million businesses in 2025.
They employed around 13.1 million people and generated estimated turnover of approximately £1.9 trillion.
Medium-Sized Businesses
Businesses with 50 to 249 employees numbered about 38,435.
Although they represented less than 1% of the total business population, they employed approximately 3.7 million people and generated around £949 billion in turnover.
UK Businesses by Industry
UK business statistics also reveal substantial differences between industries.
At the start of 2025, construction had the largest number of SMEs, with approximately 885,000 businesses, representing 16% of all SMEs.
Professional, scientific and technical activities followed with around 819,000 SMEs, while wholesale and retail trade had approximately 547,000.
Other important sectors include:
- Manufacturing
- Administrative and support services
- Accommodation and food services
- Information and communication
- Transport and storage
- Real estate activities
- Arts, entertainment and recreation
The distribution matters because business opportunities, employment patterns, investment needs, and growth prospects can vary considerably between industries.
SME Turnover by Sector
Wholesale and retail trade generated the largest share of SME turnover, accounting for approximately 32% of total SME turnover in the 2025 estimates.
Construction, professional, scientific and technical activities, administrative and support services, and manufacturing together represented another substantial portion of SME turnover.
UK Business Statistics by Region
Businesses are not distributed evenly across the UK.
ONS data for VAT- and/or PAYE-based businesses shows that London had approximately 538,000 businesses in 2025, representing 19.7% of the UK total.
The South East had around 405,000 businesses, while the East had approximately 271,000.
| Region | Businesses in 2025 |
|---|---|
| London | 538,000 |
| South East | 405,000 |
| East | 271,000 |
| North West | 266,000 |
| South West | 235,000 |
| West Midlands | 216,000 |
| Yorkshire and the Humber | 191,000 |
| East Midlands | 181,000 |
| Scotland | 173,000 |
| Northern Ireland | 80,000 |
| Wales | 105,000 |
| North East | 73,000 |
These figures are rounded and refer to VAT- and/or PAYE-based businesses rather than the entire estimated private-sector business population.
UK Business Births and Deaths
Business demography provides another important perspective by tracking businesses entering and leaving the market.
According to the latest ONS Business Demography figures for 2024:
- Approximately 317,000 businesses were born.
- Approximately 280,000 businesses died.
- The business birth rate was 11.1%.
- The business death rate was 9.8%.
- There were approximately 2.86 million active businesses.
The 2024 death rate was the lowest recorded since 2016, while the birth rate increased slightly from 11.0% in 2023 to 11.1%.
These statistics illustrate that the UK business population is constantly changing. New companies enter the market while other businesses cease trading.
Which Industry Had the Highest Business Turnover?
The answer depends on what is being measured. For example, the wholesale and retail sector had the largest share of SME turnover in the 2025 Business Population Estimates.
For business birth and death rates, however, transport and storage, including postal activities, recorded the highest rates in 2024. Its business birth rate was 15.6%, while its death rate was 16.5%.
This demonstrates why statistics should always be interpreted in context rather than used as isolated numbers.
High-Growth Businesses in the UK
High-growth businesses are another important part of the UK’s business landscape.
ONS reported 14,330 high-growth businesses in 2024, measured using employment growth. This was an increase from 13,750 in 2023.
The high-growth rate reached 4.9% in 2024, which ONS identified as the highest rate since 2018.
High-growth businesses can be particularly important for employment because rapid expansion may lead to increased hiring and demand for products and services.
Why UK Business Statistics Matter
UK business statistics are useful for many different purposes.
For Entrepreneurs
Entrepreneurs can use business data to identify industries and regions with large business populations and assess potential market opportunities.
For Investors
Investors can examine business formation, survival, industry distribution, employment, and turnover when evaluating economic trends.
For Marketers
Marketing agencies can use business statistics to understand the size of potential customer markets and identify sectors with large numbers of businesses.
For Policymakers
Government departments use business data to design policies, monitor economic conditions, and understand the needs of different business groups.
For Researchers
Researchers can use official statistics to study entrepreneurship, regional development, business survival, employment, and structural changes across the UK economy.
How to Use UK Business Statistics
When using UK business statistics in a report, article, presentation, or business plan, follow these steps:
- Identify the source. Prefer official sources such as GOV.UK and the Office for National Statistics.
- Check the publication year. Business figures can change significantly from one year to another.
- Understand the definition. A private-sector business is not necessarily the same as a VAT- or PAYE-registered business.
- Check the methodology. Understand what businesses are included or excluded.
- Use the correct geography. UK-wide figures may differ substantially from regional figures.
- Avoid comparing incompatible datasets. Different official statistics can measure different business populations.
- Cite the original source. This makes your research more transparent and trustworthy.
The Business Population Estimates are particularly useful when you need an estimate of the overall UK private-sector business population, while ONS business datasets are useful for analysing enterprise activity, location, industry, births, deaths, and survival.
