UK incorporations dipped in Q4 2025 but the effective register is still nearly 4.9 million companies.

According to Companies House, 184,888 new companies were incorporated in the UK between October and December 2025. That's a decrease of 14.4% compared with Q3 2025 (215,982), but an increase of 2% compared with the same quarter in 2024.

The total register stood at 5,450,364 companies at the end of December 2025. The effective register - excluding companies in the process of dissolution or liquidation - was 4,876,981.

The SIC code story

The quarterly decline was not evenly distributed across sectors. Construction incorporations have been under pressure given the sector's ongoing insolvency crisis. Real estate formations have softened, reflecting higher interest rates dampening buy-to-let and property investment activity.

But other sectors show resilience. IT consultancy and professional services registrations continue to account for a significant share of new formations. Technology-oriented incorporations remain a bright spot nationally.

The geographic picture

England and Wales saw the largest absolute decrease (28,989 fewer incorporations than Q3 2025, a 14.3% drop). Scotland saw a 14.6% decrease and Northern Ireland dropped 18.7%.

London typically accounts for around 28-30% of all UK incorporations, and any dip in London activity drags the national average. Regional cities like Leeds, Bristol, Edinburgh, and Manchester have been growing their share of new formations in recent years, driven by lower costs and growing tech clusters.

What's behind the quarterly dip

Two factors likely contributed. First, Companies House introduced identity verification on 18 November 2025 as a legal requirement under the ECCT Act. The new process, while straightforward for most, may have slowed some incorporations in the short term. Additionally, the general tightening of formation agent due diligence has likely reduced the volume of potentially spurious incorporations.

Second, Q3 2025 was a relatively strong quarter for formations. Some of the Q4 decline is simply a reversion to trend.

The bigger picture

With nearly 4.9 million companies on the effective register, the UK company population remains historically large. The register has more than doubled since the 2008-09 recession. A single quarterly dip does not signal an entrepreneurship crisis.

UK business formation isn't dying. It's shifting - geographically, sectorally, and structurally. The register data says so.
