Working with a high net worth mortgage broker
A high net worth mortgage broker specialises in presenting complex wealth to lenders in the way each lender assesses it, comparing mainstream large loan desks, specialist lenders, and private banks across the whole market.
Because HNW and large mortgage lending is manually underwritten, outcomes vary significantly between lenders for the same borrower. An HNW mortgage broker can approach multiple institutions, negotiate pricing and AUM conditions with private banks, and structure the application, income evidence, ownership vehicle, repayment type, and valuation approach, before submission.
Using a whole-of-market HNW mortgage broker also protects borrowers from an unnecessarily narrow view of the market, for example approaching only their existing private bank when better terms may be available elsewhere.

Frequently asked questions
What does a high net worth mortgage broker do?
A high net worth mortgage broker compares mainstream large loan desks, specialist lenders, and private banks across the whole market, structures the application, and negotiates terms. Because HNW lending is manually underwritten, the same borrower can receive materially different offers between lenders, making broker comparison valuable.
Are high net worth mortgages more expensive?
Not necessarily. High net worth mortgage pricing is often negotiated individually, and strong asset positions can secure competitive terms. However, complex structures, offshore ownership, or unusual properties can increase pricing. Any assets under management requirement should be factored into the true overall cost.
Are high net worth mortgages regulated by the FCA?
Yes, high net worth mortgages on a borrower's home are regulated by the Financial Conduct Authority (FCA). The high net worth exemption tailors certain conduct rules but does not remove regulation. Buy-to-let lending to high net worth borrowers is usually unregulated unless it meets consumer buy-to-let criteria.
Can I get an interest-only high net worth mortgage?
Yes, interest-only high net worth mortgages are widely available. Lenders accept credible repayment strategies such as investment portfolios, sale of other assets, or future liquidity events. Part-and-part structures combining interest-only and repayment elements are also available where a lender caps the interest-only portion.
Who qualifies as a high net worth mortgage customer?
A high net worth mortgage customer is defined by the Financial Conduct Authority (FCA) as a borrower with an annual net income of at least £300,000 or net assets of at least £3 million. The definition sits within the Mortgages and Home Finance: Conduct of Business sourcebook (MCOB) and must be evidenced.
