Regulatory status

Totwell Vetta operates as a data and analytics provider for property deal validation. Totwell Vetta is not authorised or regulated by the Financial Conduct Authority and is not on the Financial Services Register. Nothing on this platform, in a validation report, or in any communication from us constitutes financial advice, investment advice, or a personal recommendation to buy, sell, invest in or finance any specific property or deal.

Because we are not authorised, you are not covered by the Financial Services Compensation Scheme in respect of anything you do through the platform, and complaints about us cannot be referred to the Financial Ombudsman Service. Validation outputs are descriptive analytical outputs, not guarantees of value, return or outcome. Property investment carries risk, including the risk of capital loss.
