A third of all British businesses sit in just two regions. Wales lost 26,000 businesses in a single year. And the fastest startup growth is happening about as far from London as you can get.
Most market sizing treats the UK as one market. The official numbers say otherwise.
The national picture
- 5.7 million private sector businesses in the UK at the start of 2025
- England 5.0 million · Scotland 361,000 · Wales 194,000 · Northern Ireland 139,000
- 99.2% are small (0 to 49 employees); 75% employ nobody but the owner
- SMEs employ 16.9 million people (60%) of the private sector workforce and turn over £2.8 trillion (51%)
Where the businesses are
London has 1.04 million private sector businesses and the South East 877,000. Together that is 34% of the entire UK business population in two regions.
Density tells the sharper story. Businesses per 10,000 adults:
- London: 1,436
- South West: 1,163
- South East: 1,135
- East of England: 1,102
- North East: 744 (lowest in England)
- Wales: 742 (lowest in the UK)
A Londoner is surrounded by nearly twice as many businesses per head as someone in the North East or Wales. That is competition if you are selling, and opportunity if you are choosing where to compete.
Who grew and who shrank
Over the year, business numbers rose by 206,000 in England, 6,000 in Scotland and 6,000 in Northern Ireland. Wales fell by 26,000, the only nation to shrink.
New formation is a different map again. London still takes roughly a third of all new incorporations (around 30 new businesses per 1,000 residents in 2025, with Manchester leading the rest at 18.5 per 1,000), but the fastest growth in company formation is in the North East (up 5.3%), Scotland (up 4.3%) and the North West (up 3.6%).
What this means for your business
First, benchmark locally, not nationally. “The average UK business” is a statistical fiction stretched across a 2x difference in density. Your competition level depends on your postcode.
Second, low-density regions cut both ways. Fewer competitors per head, but often a thinner market. The interesting cases are where density is low and formation growth is high: the North East and Scotland right now. New businesses need everything, from accountants to signage, and there are structurally fewer incumbents fighting for them.
Third, if you serve customers nationally from a cheap-rent region, you are playing the arbitrage that the data supports. The businesses are in the South East. The growth is increasingly not.
