How Many New Businesses Were Registered in the UK in 2025?
The UK business population stood at 2.73 million VAT/PAYE-registered businesses by March 2025. Companies made up 76.7% of all businesses. In Q4 2025, creations outpaced closures by over 6,000, with 15 of 16 major industrial groups posting year-on-year increases.
The strongest creation increases came from transport and storage, and information and communication.

That 9.6% rise was partly driven by Companies House’s expanded powers under the Economic Crime and Corporate Transparency Act.

Insurance application data from Protectivity, tracking registrations between 2024 and 2025, shows which business types people are actually starting.

What Does the Data Tell Us About the Fastest Growing Business in the UK for 2026?
Two patterns are running in parallel. At the micro level, sole-trader businesses in fitness, cleaning, and crafts are growing at triple-digit rates. Low entry costs and local demand keep the barrier to entry low. At the macro level, the fastest-growing companies by revenue sit in fintech, AI, and energy — sectors pulling the bulk of venture capital and posting three-year sales growth above 400%.
Both ends of the spectrum share one thing: a net-positive rate of business creation over closure. The UK is adding roughly 6,000 more new businesses than it loses per quarter as of late 2025. The UK’s PMI hit a 15-month high of 50.6 in December 2025. Whether that momentum holds through 2026 depends on consumer spending and global rate conditions. The broader trends shaping 2026 suggest continued growth in AI-driven businesses and service-sector startups.
