Data published today by anti-money laundering technology provider SmartSearch suggests that potentially £464million in dirty money is flooding the high street economy.
The study, which analysed Companies House records from 2016 to 2026, flagged 3,097 dissolved businesses whose patterns of registration and closure were inconsistent with genuine commercial activity in their respective sectors.
Conservative financial modelling, drawing on figures published by the National Crime Agency and the National Economic Crime Centre, puts the sum potentially channelled through these firms at between £310million and £464million.

When the three other cash-heavy industries highlighted in the 2025 National Risk Assessment, car washes, nail bars and phone shops, are factored in, the total over the past decade likely surpasses £1billion.
These suspected entities survived an average of just 170 to 194 days, less than half a year, against a backdrop where the typical dissolved UK company lasts nearly five years on the register.
Some 83 per cent of the hairdressing-related firms and 92 per cent of the convenience store entries were set up during the first or second quarter of the year, with more than half wound down in the final quarter.
The rate of suspected registrations surged by over 340 per centOne area of Cardiff alone accounted for 119 suspected companies spanning both sectors. when comparing the 2016–2018 period with 2023–2025, outstripping both heightened regulatory attention and prominent enforcement actions during the same window.

One area of Cardiff alone accounted for 119 suspected companies spanning both sectors. In London, a single formation agent address served as the registered office for 17 hairdressing and beauty firms between 2018 and 2023, all exhibiting near-identical lifespans and dissolution timelines.
Operation Machinize, a coordinated NCA enforcement effort in 2025 targeting cash-intensive businesses, rescued 97 people identified as potential modern slavery victims during just one three-week phase of the operation.
The funds moving through the kinds of suspected shell companies identified in the SmartSearch analysis are linked to drug trafficking, exploitation, fraud and other serious criminal activity.
Nearly half of the suspected hairdressing firms, and more than a third of the convenience store entries, relied on one of just five generic words in their company names, further suggesting a formulaic approach to their creation.

Phil Cotter, the chief executive of SmartSearch, said: “This is not a story about small businesses failing. It is a story about patterns that suggest a repeatable model of exploitation operating openly across UK high streets, and accelerating faster than the regulatory response has been able to catch.”
He acknowledged that Companies House had made meaningful strides since the Economic Crime and Corporate Transparency Act took effect, but stressed that the register continued to expose patterns indicating the underlying criminal activity was outpacing reform.
Mr Cotter added: “The direction of policy is right. The volume and speed of the response now needs to match the volume and speed of what the data still shows.
“The system isn’t standing still, and Companies House has done more than most people realise. But the data suggests the underlying model of exploitation is more entrenched, more systematic, and moving faster than even the current pace of reform has been able to catch.”
Companies House has nonetheless undertaken substantial work under the powers granted by the 2023 Act. In the year to March 2026, it stripped 151,000 registered office addresses from the register, removed 119,000 officer addresses and 95,200 addresses linked to persons of significant control, and redacted 77,900 incorporation documents.
More than 158,000 companies were subject to compliance action during that period. Mandatory identity verification for incoming directors and persons of significant control became a requirement on November 18, 2025, with 3.81 million personal codes issued to date.
