Britain's active business population reached a record 5.66m this month, according to the New Startup Index published by NatWest with the data company Beauhurst 1. Over the same series, 402,000 new companies registered with Companies House in the first half of 2026, down 5.7% year on year. NatWest attributes part of that fall to regulatory reforms cutting out low-intent and fraudulent registrations, the kind Companies House gained identity-verification powers to strip out.
Those two numbers only make sense together. The stock of trading businesses is at a record while the inflow is being filtered at the door, which is what a registry clean-up looks like in the data. Four hundred thousand registrations that are all real feed a better funding pipeline than half a million that are not, so the fall reads as a cleaner series rather than as a cooling one. Anyone quoting the 5.7% on its own, in either direction, is quoting half a measurement.
Application software led every category with 28,100 incorporations. Scotland posted the strongest regional growth at 3.73% against the second half of 2025, ahead of the East Midlands at 3.3%, and London still took more than 136,000 new companies. Regional growth rates off small bases move easily; London's absolute share does not. HM Revenue and Customs recorded the funding side of that pipeline thinning last year, with the number of individuals claiming Enterprise Investment Scheme relief down 7% to 33,220 .
