Aipedia: Mortgage brokers
A mortgage network that uses AI to check its appointed representatives' files is still responsible for their conduct, and its PI must cover them. AI can review far more files than people can, but it can also miss the problems that matter most.
Part of: AI in Mortgage brokers
In short
Networks and principal firms increasingly use AI to review appointed representatives' case files for missing documents, inconsistencies and suitability concerns. This allows far wider coverage than manual sampling. But a network remains responsible for its ARs, and its PI must cover their conduct: MIPRU 3.2.4R requires it and MIPRU 3.2.5R and 3.2.6R treat employees and ARs as part of the firm for PI purposes. An AI review that misses a pattern of poor advice can leave the network facing many claims. SYSC 8.1.6R applies to the review tool itself.
File checking tools read every case submitted by an AR: fact-find, sourcing record, recommendation letter, ID, income evidence and protection documents. They flag missing items, inconsistencies between documents and patterns such as high use of one lender or unusual product choices. Compliance staff then review flagged files. Some networks use AI to grade files and decide which ARs need closer supervision.
For how AR status affects PI, see PI for appointed representatives and directly authorised versus AR.
File tools are good at checking that documents exist and agree with each other. They are weaker at judging whether the advice was right for the borrower. A complete, consistent file can still contain unsuitable advice: a loan that is technically affordable but stretches a vulnerable borrower, a product transfer that ignored a better remortgage, or protection cover that does not match the family's needs. AI-drafted letters make this harder, because they produce tidy files whatever the quality of the advice. See AI-drafted recommendation letters.
Illustrative scenario: a network moves from manual sampling to AI review of every file. One AR's files score well: complete, consistent and well written. Behind them, the AR has been routinely recommending interest-only lending without a credible repayment strategy, which the tool was not set up to question. When complaints arrive, the network faces a series of claims from one AR, with the question of why its supervision did not catch the pattern.
The reverse problem also occurs. A tool tuned to flag too much can bury compliance staff in alerts, so the important ones are cleared in bulk. Either way, the network needs evidence that it understood what the tool was checking, tested it against known problem files, and adjusted it when it missed things. That evidence matters to the FCA, to the Ombudsman and to the network's own insurer when complaints arrive.
Networks commonly hold a PI programme that covers their ARs, as MIPRU requires. Claims arising from an AR's advice are usually handled under the network's policy, subject to its terms, and the network may seek to recover the excess or other costs from the AR under the AR agreement. A series of claims from one AR may raise aggregation and limit questions, and may affect the network's renewal. Insurers may ask how files are checked, including the use of AI.

Apex arranges PI for mortgage firms, including directly authorised firms considering their own cover, and can explain how network and direct arrangements differ. See the mortgage broker AI hub.
Yes. A principal firm is responsible for its ARs' regulated activities, and its PI must cover their conduct under MIPRU 3.2.4R. If an AR's AI tool causes poor advice, claims usually fall under the network's arrangements.
It can widen coverage but is weaker at judging advice quality. The FCA's 2026 good practice review stresses accountability and auditable records. Networks can keep human review alongside AI, focused on the highest-risk cases.
Record how the tool is configured, what it checks, how it was tested, what it flagged, what reviewers decided and why, and changes made after problems were found. The FCA's 2026 good practice review stresses auditable decision records.
Usually an AR is covered by the network's PI, as MIPRU requires the principal's policy to cover AR conduct. The AR agreement may set out how excesses and costs are shared, so check it carefully.
