What counts as a high net worth mortgage
Under FCA mortgage rules, a high net worth mortgage customer is broadly one with net annual income of at least £300,000 or net assets of at least £3 million. Borrowers who meet this threshold can be assessed under a more flexible framework than the standard affordability model - which matters because standard income multiples and automated underwriting rarely reflect how genuinely wealthy individuals structure their income and assets.
In practice, high net worth mortgage lending covers company founders and directors, partners in professional firms, senior finance and private-equity professionals, and individuals with substantial investment portfolios or property wealth. The common thread is that the borrowing decision turns on the overall balance sheet and relationship, not a single payslip.
How high net worth income is assessed
The most important variable for a high net worth borrower is usually not the loan size but how income is assessed. A high-street lender using salary plus dividends will often produce a far lower maximum loan than a private bank or specialist lender that recognises the borrower's true earnings and assets.
Bonus, dividend and carried interest
Specialist lenders and private banks will consider variable and performance-linked income - discretionary bonuses, dividends drawn from a trading company, and carried interest for private-equity and fund professionals - where standard lenders discount or ignore it. The treatment varies by lender, which is why matching the borrower to the right underwriting approach is the core of the exercise.
Retained profit and director income
Company directors are frequently under-served by salary-and-dividend assessment because profit retained in the business for tax efficiency is invisible to standard affordability. Specialist lenders can assess net profit or the borrower's share of retained earnings, producing a materially higher borrowing figure on the same underlying business.
Asset-backed and investment income
Where earned income is modest relative to wealth, private banks can lend against the strength of an investment portfolio, property assets, or cash under management. Assets under management with the bank, securities-backed lending, and pledged collateral all feature in bespoke high net worth structures.
Private bank mortgages
For larger and more complex requirements, private banks - including names such as Coutts, Arbuthnot Latham, Investec, Hampden & Co, and C. Hoare & Co - offer relationship-led mortgage lending underwritten by a person rather than a system. Pricing and terms are bespoke, frequently tied to a wider banking or wealth-management relationship, and structured around the client's tax position, currency, and liquidity. Private bank lending is best suited to loans above roughly £1 million or to borrowers whose income and asset profile does not fit a standard template.
Interest-only and large loan options
High net worth borrowers often prefer interest-only structures, servicing the interest from income and repaying capital from a bonus cycle, an asset sale, or an investment maturity. Specialist and private bank lenders accommodate interest-only where the repayment strategy is credible, and can advance large loans well beyond the ceilings applied by mainstream lenders. Offset facilities, multi-currency lending, and flexible overpayment terms are all available within bespoke arrangements.
Why a specialist broker matters for high net worth lending
The high net worth market is relationship-driven and much of it is not accessible directly. Private banks typically take introductions through trusted intermediaries, and specialist large-loan lenders reserve their most competitive terms for broker-submitted business.
