Why it exists

This standard sets out what a defensible specialist lending file must contain, so that a firm can prove why each recommendation or referral was right for the client, years after completion.

Complaints about secured lending often arrive five or more years after completion, through a subject access request or a claims firm. By then the adviser may have left and memory has gone. If the reason is not on file, the firm cannot defend the case.

Could a stranger, reading only this file in six years' time, see why this was right for this client?
The one test every file must pass

Six sections

Every section applies the seven core principles →

Four grades

Technology · For software providers

Build it into your system

The rule pack turns each required item into a rule your software can check: an id, when it applies, the fields it reads and the grade a file gets if the item is missing. It sits at one stable URL, as JSON.

Any software provider may implement the standard. There is no fee to say a product is "built to the standard". Section A's rules are complete in v0.1; the rules for sections B to F will be added in a later version.
