High net worth mortgages

A high net worth mortgage is a residential loan for borrowers with significant income or assets, where the lender looks at total wealth rather than a simple income multiple. Under FCA rules a high net worth mortgage customer has annual net income of at least £300,000 or net assets of at least £3 million (FCA Handbook, accessed 20 Oct 2026).

Meeting that definition allows a lender to apply some tailored rules, but only with evidence. The lender either already knows the customer meets the definition through an existing relationship, or it receives a signed statement from the customer's own qualified adviser confirming it. Many borrowers who use high net worth lenders never formally opt into the definition at all.

In everyday use the term covers a wider group. Borrowers with high but irregular earnings, large investment portfolios, business owners who draw little salary and international clients with income in several currencies are often described as high net worth cases, whether or not they meet the regulatory test. High net worth mortgages UK lenders offer are therefore a broad category rather than one product.

High net worth lending works by underwriting the whole balance sheet. Instead of applying a standard income multiple, the lender reviews income from every source, liquid and illiquid assets, existing borrowing and the planned exit, then decides how much it is comfortable to lend. Decisions are usually made by a credit committee rather than an automated system.

This manual approach is what allows larger and less conventional loans. A lender may accept bonus, dividend, rental and investment income together, look through company structures, or lend against a property while taking comfort from a separate investment portfolio. The trade-off is that each case takes longer to prepare and more documents are needed up front.

Loan sizes vary widely. Some high net worth borrowers need a few hundred thousand pounds of flexible borrowing, while others need multi-million pound loans on prime property. The guide to large and million-pound mortgages explains how lenders approach the biggest loans and what borrowers are asked to show.

High net worth borrowing can also sit alongside other lending. A single lender may provide the mortgage, a credit line secured on investments and banking services, and look at the relationship as a whole when setting terms.

High net worth mortgages suit borrowers whose finances do not fit the standard income-multiple model used by most high street lenders. Typical applicants include senior professionals with large bonuses, company owners, partners in professional firms, investors with significant portfolios, people with inherited wealth and buyers whose income is earned in several countries.

Lenders want to see that the loan is affordable and that there is a credible way to repay it. For a repayment mortgage that means sustainable income. For interest-only, it means a clear repayment strategy, such as the sale of investments, the sale of the property or other assets that can be realised when the term ends.

Age, residency and credit history still matter. Some lenders set minimum income or asset levels for their high net worth range, and private banks may expect the borrower to hold investments or deposits with them. Others focus purely on the property and the loan, so criteria differ widely from one lender to the next. The large mortgage calculator is being built to give a first estimate from your own income, deposit and loan figures.

Lenders assess complex income by looking at how it is earned, how stable it is and how much of it can be relied on in future. Bonuses, commission, carried interest, dividends, rental income and drawings from a partnership or company are each treated differently, and most lenders average variable income over several years of accounts.

Self-employed borrowers and company directors are usually asked for full accounts, tax calculations and a letter from their accountant. Where profits are retained in a company rather than paid out, some lenders will consider the share of retained profit as well as salary and dividends. Others look only at what is drawn personally.

Assets can support a case in several ways. Liquid investments may give a lender comfort that payments can be met, form the planned repayment route for an interest-only loan or, at some lenders, be pledged as extra security. Lenders will want statements showing ownership, value and how easily each asset could be sold.

Documents from outside the UK, foreign currency income and assets held in trusts or offshore companies all add work. Lenders may ask for certified translations, local tax returns and legal opinions before they can rely on them.

Private banks are one of the main sources of high net worth mortgages. They lend to clients with significant assets on flexible terms, and may price the loan with the wider banking relationship in mind. Many expect the borrower to move some investments or cash to the bank, either as a condition of the loan or to secure better terms.

Specialist and high street lenders also have high net worth and large loan ranges. These often have higher loan limits and more flexible underwriting than standard products, without requiring assets to be placed with the lender. Some are only available through brokers.

The right fit depends on the case. A borrower who wants a single banking relationship may value a private bank's service, while one who prefers to keep investments elsewhere may look first at specialist lenders. How the two compare, and what private banks typically ask for, is covered in the guide to private bank mortgages.

Whichever route is used, the lender carries out its own affordability assessment and valuation. Holding assets with a bank does not remove the need to show the loan is suitable and can be repaid.

High net worth mortgages often use structures that are less common in standard lending. Interest-only is widespread for larger loans, with the capital repaid from investments, a property sale or other assets. Part-and-part loans split the balance between interest-only and repayment, and some lenders allow payments to be reduced or paused when agreed in advance.

A high net worth interest only mortgage needs a repayment strategy that the lender accepts at the outset and reviews over the term. Lenders usually set rules for what counts, such as a minimum value of investments or equity remaining in the property, and they may ask for updates during the loan. The interest-only calculator shows how monthly payments compare with a repayment loan using your own figures.

Offset arrangements link the mortgage to savings so that interest is charged only on the difference. Other bespoke features include multi-currency lending, loans secured on several properties and facilities that let the borrower draw and repay funds within an agreed limit. Each lender offers its own mix, and the features available can change the overall cost of borrowing.

A bespoke mortgage is not a regulated product name. It simply describes a loan whose terms have been tailored to the borrower, so two bespoke offers from different lenders can look very different.

International clients can get high net worth mortgages in the UK, but they face extra checks. Lenders look at where income is earned and in which currency, the borrower's residency and tax status, and how easily overseas assets can be verified. Some lenders apply a lower maximum loan to foreign currency income.

Currency risk is a key concern. If income is earned in one currency and the loan is in sterling, a change in exchange rates can make payments harder to meet. Lenders may reduce the income they count, or offer a loan in the same currency as the income where that suits the borrower.

Tax changes also affect some international borrowers. Rules for people who are not UK domiciled changed significantly in recent years, and lenders now focus on residence and the source of funds. How lenders treat non-UK residents, overseas income and offshore ownership is explained in the guide to international and offshore high net worth mortgages.

Buying through an offshore company or trust adds legal and tax steps. Lenders will want to understand who owns and controls the company, and borrowers usually take independent legal and tax advice before choosing a structure.

Getting a high net worth mortgage starts with preparing a clear picture of income, assets and the purpose of the loan. Most borrowers work with a broker who handles large loans, because many lenders in this market deal mainly through intermediaries and each case is presented individually to a credit committee rather than scored online.

A typical process starts with an initial review of the borrower's position and goals. The broker then approaches suitable lenders with a summary of the case, gathers indicative terms and agrees which lender to proceed with. A full application follows, with documents, a valuation and legal work on both sides before an offer is issued.

Good preparation shortens the timescale. Up-to-date accounts, investment statements, proof of deposit, identification and an explanation of any unusual income or assets all help. Complex cases with trusts, companies or overseas income can take longer, so starting early is sensible.

Brokers who specialise in this market differ in how they charge, which lenders they work with and the size of loan they usually arrange. What to look for when choosing one is covered in the guide to high net worth mortgage brokers.

The cost of a high net worth mortgage depends on the lender, the loan size, the loan-to-value, the structure and the wider relationship. Pricing is often agreed case by case rather than taken from a published rate table, and private banks may offer different terms depending on the assets held with them.

Borrowers usually pay a lender arrangement fee, which may be a fixed sum or a percentage of the loan, plus valuation and legal fees. Large and unusual properties can need specialist valuers, which adds cost and time. Some brokers charge a fee as well as, or instead of, receiving a payment from the lender.

Early repayment charges, the cost of switching at the end of a deal and any requirement to hold assets with the lender should all be compared alongside the rate. What moves the price of high net worth lending, and how pricing is quoted, is explained in the guide to high net worth mortgage rates.

Stamp duty and other taxes on the purchase are separate from the mortgage costs. They can be significant on higher-value property and should be budgeted for alongside the deposit and fees.

High net worth mortgages go by several other names. Lenders and brokers may call them HNW mortgages, bespoke mortgages, wealth mortgages, high value mortgages or large loans. The terms high net worth lending, high net worth finance and high net worth borrowing are used for the wider range of secured loans offered to wealthy clients.

An asset backed mortgage usually means a loan where investments or other assets support the application or form extra security. A high income mortgage is sometimes used for borrowers with large salaries who still fit standard criteria. A high net worth residential loan is simply a mortgage on a home rather than an investment property.

Whatever the label, the features to compare are the same: how the lender assesses income and assets, the maximum loan, the structure, the total cost and any conditions attached to the relationship.
