Public records confirm it is anti-money-laundering supervised by HMRC, a member firm of CIOT, and running a confirmed website. Its website shows it handles Self Assessment, Payroll, Contractor, and CIS. We have not matched this listing to a Companies House company, so we hold no incorporation date or filing history for it. That can mean a sole trader, or an accountant trading through a company we have not yet linked.
