A high net worth mortgage is a loan of £1m or more, assessed on your overall wealth, asset base, and multiple income sources rather than a simple salary multiple. The FCA defines a high net worth individual as someone earning over £300,000 annually or holding £3m or more in net assets. Lenders read that test literally and count the equity in your main residence, and usually your pension, towards it. If you fall into either category, you qualify for enhanced underwriting from private banks and specialist lenders that standard high street criteria cannot match.
Fox Davidson arranges high net worth mortgages from £1m to £30m and above. We have been placing complex income cases with private banks and specialist lenders since 2013. Most high net worth cases we handle complete within four to ten weeks of the initial call, depending on income complexity and property type.
What separates a high net worth mortgage from a standard mortgage?
The fundamental difference is underwriting approach. Standard mortgages run your application through an algorithm. High net worth mortgages are assessed by a human underwriter who reviews your full financial picture, including business interests, investment portfolios, trust structures, and income from multiple jurisdictions.
| Feature | Standard Mortgage | High Net Worth Mortgage |
|---|---|---|
| Typical loan size | Up to £1m | £1m to £30m+ |
| Underwriting | Algorithm-based | Relationship-driven, manual |
| Income types accepted | PAYE, simple self-employment | Bonuses, carried interest, dividends, foreign currency, investment income |
| Typical clients | Standard homebuyers | Entrepreneurs, fund managers, partners, expats |
| Lender types | High street banks | Private banks, specialist lenders |
Why high street lenders cannot serve high net worth borrowers
High street banks are configured for PAYE borrowers with predictable, documented income. Their affordability models typically discount bonus income by 50% or more, ignore carried interest entirely, and do not recognise stock options, profit distributions, or overseas earnings. The result is that a high street bank may offer you £1.1m when your actual borrowing capacity, properly assessed, exceeds £4m.
Standard lenders also struggle with company structures, SPVs, trusts, non-sterling income, and recently formed businesses. FCA stress testing requirements force them into rigid automated models that reject profiles private banks would approve without hesitation.
How private banks and specialist lenders assess high net worth borrowers
Private banks operate on a relationship model. A dedicated relationship manager reviews your case manually and structures the debt around your investment portfolio, business interests, and long-term financial plan. Some private banks in 2026 require assets under management (typically £1m to £3m with their wealth management division), while others provide “dry lending” with no AUM requirement.
| Feature | High Street | Specialist Lender | Private Bank |
|---|---|---|---|
| Typical loan range | £100k to £2m | £1m to £15m+ | £3m to £30m+ |
| Underwriting | Automated | Semi-manual | Fully manual, relationship-led |
| AUM requirement | None | None | Often £1m+, or dry lending |
| Complex income flexibility | Limited (50% bonus discount) | Moderate (case-by-case) | High (100% recurring bonuses possible) |
According to the Bank of England, the current base rate is 3.75% as of April 2026. Private bank fixed rates for prime HNW cases broadly track 1.0% to 1.5% above base rate with substantial deposits.
How high net worth mortgage underwriting works
Underwriting at this level is holistic. The lender evaluates your recurring income from all sources, your asset base (property, businesses, investment portfolios), existing leverage across your balance sheet, resilience under interest rate stress tests, and the quality and liquidity of referenced assets.
For irregular income such as bonuses, carried interest, and performance fees, lenders examine three to five year averages looking for repeat patterns and pipeline visibility. Jurisdictional risk and FX exposure matter for clients paid in USD, EUR, CHF, or AED, with haircuts typically ranging 10% to 25% for foreign currency income.
Worked example: £2.5m interest-only mortgage
| Income component | Gross annual | Bank treatment | Credited amount |
|---|---|---|---|
| Base salary | £250,000 | 100% | £250,000 |
| 3-year average bonus | £400,000 | 100% (documented) | £400,000 |
| Dividend income | £80,000 | 100% | £80,000 |
| Rental income (net) | £45,000 | 100% | £45,000 |
| Total assessed income | £775,000 |
This income supports borrowing well exceeding £2.5m on private bank multiples of 4.5x to 6x. A high street lender assessing the same client would likely credit only £250,000 base plus £200,000 (50% of bonus), ignoring dividends and rental income, and cap the offer around £2m.
Case studies: how Fox Davidson places complex HNW cases
£4.2m interest-only, Kensington townhouse
A hedge fund partner with a £180,000 base salary and substantial USD bonuses and carried interest averaging £650,000 annually over four years. Two high street banks declined, crediting only 50% of bonuses and zero carried interest. Their maximum offer was £1.1m against a £7.5m purchase.
We presented a detailed income narrative to three private banks emphasising four-year bonus consistency, carried interest pipeline, and liquidity reserves exceeding £2m. A leading private bank approved £4.2m interest-only at 56% LTV with a competitive five-year fixed rate. The exit strategy was documented as continued earnings and eventual property sale.
£7.5m facility, Cotswolds country estate
A tech entrepreneur completing a business exit, receiving £18m net of tax. Post-exit he had low provable ongoing income but substantial liquid assets in a diversified portfolio. He wanted a £12m estate without liquidating investments. High street banks and building societies declined, citing lack of regular income.
We positioned this as an asset-based lending case with a private bank comfortable with securities-backed lending. The £18m investment portfolio was referenced (not fully pledged) as additional comfort, with a clear exit tied to a planned 15-year portfolio drawdown. The private bank provided a £7.5m blended facility, and the client preserved investment returns estimated at 7% to 10% annually rather than liquidating.
£2m mortgage, non-UK resident buying in Knightsbridge
A Middle East-based senior corporate executive paid primarily in USD with no UK credit history. Time-sensitive new-build completion required certainty. We selected an international private bank with cross-border expertise and USD income comfort from the Gulf region. Documentation was pre-curated addressing source of funds and employment verification upfront. The bank approved £2m at low LTV with a five-year fixed option and full currency risk analysis. Completion was achieved within eight weeks despite non-resident complexity.
Types of high net worth mortgage product
| Type | Indicative loan size | Typical use |
|---|---|---|
| Capital and interest | £1m to £10m+ | Primary residence, long-term hold |
| Interest-only | £1m to £30m+ | Cash flow optimisation, investment-focused |
| Part-and-part | £1m to £15m+ | Balanced approach with partial amortisation |
| Large buy to let | £1m to £20m+ | Portfolio landlords, multi-property investors |
| Development or refurbishment exit | £1m to £10m+ | Replacing bridging after major renovation |
Interest-only structures remain the most common choice for high net worth borrowers. The logic is straightforward: if your investments return 8% to 10% annually, paying 4% to 5% mortgage interest and keeping your capital deployed represents positive carry. The essential requirement is a clear, credible repayment strategy documented at application, whether that is property sale, portfolio drawdown, or a planned business liquidity event.
Complex income: how private banks treat what high street lenders reject
Bonuses and carried interest
Investment bankers, hedge fund partners, and private equity professionals rely heavily on variable compensation. Private banks in 2026 often credit 100% of recurring bonuses or carried interest where there is a proven multi-year track record. A private equity partner whose £200,000 base salary would support only £900,000 on 4.5x multiples can borrow £3.15m when a documented five-year average bonus of £500,000 is fully credited.
Documentation expectations include bonus award letters, historic payslips, carried interest schedules, and fund documentation confirmation. If you are an investment banker or fund manager, the quality of your documentation package determines whether you get 50% or 100% credit on variable income.
Dividends and business owner income
Entrepreneurs frequently draw modest salaries for tax efficiency, relying on dividends and retained profits. Private banks analyse full company accounts, EBITDA, cash reserves, and retained earnings rather than just the salary and dividend figure on your SA302. One case we placed involved a UK limited company director with three years of £450,000 average pre-tax profits despite a £50,000 personal salary. A private bank approved £2.8m that high street banks had declined.
Investment and rental income
Clients living primarily from investment portfolios or substantial rental income need lenders comfortable assessing these sources without demanding PAYE income as a prerequisite. Private banks underwrite based on sustainable withdrawal rates, typically 3.5% to 4% for diversified portfolios, or net rental income. A client with £8m in listed securities and no employment income can secure an interest-only facility based on a 3.75% modelled sustainable drawdown, demonstrating £300,000 annual income equivalent.
International and foreign currency income
Specialist and private banks commonly accept USD, EUR, CHF, AED, and other major currencies subject to FX haircuts of 10% to 25% and jurisdiction risk assessments. If you are a US law firm partner paid in USD or a Gulf-based executive, the lender selection matters more than the rate. A bank with genuine cross-border expertise will credit your income fairly. One without it will either decline or discount it so heavily the offer is unusable.
How the application process works
- Initial consultation. Confidential discussion of your objectives, property plans, income structure, and any constraints. We assess which lenders fit your profile before any formal approach.
- Strategy and lender selection. We identify two to four lenders suited to your case and negotiate indicative terms before formal application. This avoids unnecessary credit searches and wasted time.
- Documentation and presentation. We compile your financial evidence into a structured application package that pre-empts underwriter questions. For complex income, this narrative is the single most important factor in approval.
- Credit approval. Formal underwriting, typically with direct access to the decision-maker through private banking relationships. We do not submit to portals and hope for the best.
- Valuation and legals. Coordinating surveyors and solicitors, managing timelines. For prime properties, we ensure the valuer has appropriate experience with the asset class.
- Completion. Funds drawn, property purchased or refinanced.
Realistic 2026 timescales: standard high net worth approvals complete in four to ten weeks depending on complexity. Bridging finance, where needed to secure a property while the mortgage completes, can be arranged in parallel through our bridging team.
Documentation you will need
Requirements vary by lender type and residency status, but expect to provide most of the following: passport and proof of current address, UK and overseas tax returns (two to three years), bank statements for all main accounts (six to twelve months), company accounts (two to three years if applicable), investment portfolio statements (current plus twelve-month history), trust deeds or SPV documentation where relevant, bonus award letters and historic payslips, carried interest schedules and fund documentation, property sale contracts or gift letters for the deposit source, and AUM summaries if you are seeking relationship pricing from a private bank.
International clients typically provide additional documentation including foreign credit reports and employer verification. We advise compiling documentation before your first call. The more complete the package at the outset, the faster the process moves.
When to speak to a broker
Three to six months before your planned purchase or refinance. For complex situations involving substantial carried interest, cross-border structures, or significant tax planning, six to twelve months is not too early. Early discussion allows us to assess lender criteria, identify the strongest options, and build the documentation package properly rather than rushing near exchange.
If you are buying at auction or need to move quickly on a property, we can run the private bank process and a parallel bridging application simultaneously to secure the asset while the longer-term mortgage completes.
Frequently asked questions
What net worth qualifies for a high net worth mortgage in 2026?
The FCA high net worth exemption applies to individuals with £300,000 or more in annual income or £3m or more in net assets. Lenders read that test literally and count the equity in your main residence, and usually your pension, towards it. Many private banks begin applying enhanced underwriting at lower thresholds, around £1m loan size or £150,000 income, before the formal FCA exemption kicks in. Qualification depends on income stability, asset quality, and loan-to-value rather than a single net worth figure.
Do I have to be UK resident to get a £1m+ mortgage on UK property?
No. We regularly arrange finance for expats and non-UK residents purchasing investment properties or future homes in London and prime areas. Lenders scrutinise currency exposure, country risk, employment stability, and source of funds more carefully, and the lender panel is narrower, but the rates and terms are competitive for well-documented cases.
What is the minimum deposit for a high net worth mortgage?
LTV ratios typically range from 50% to 75% for large loans with private banks, meaning deposits of 25% to 50% are common. Some specialist lenders extend to 80% to 85% LTV for exceptionally strong profiles with substantial liquid assets. The key factors determining LTV are property location and type, income resilience, overall net worth, and depth of the lender relationship.
Can I still get an interest-only mortgage for a large loan?
Yes. Interest-only mortgages remain widely available for high net worth borrowers through private banks and specialist lenders. The essential requirement is a clear, credible repayment strategy documented at application. Acceptable exits include planned property sale, investment portfolio drawdown, anticipated business sale or liquidity event, or proceeds from other property disposals.
How far in advance should I speak to a broker?
Three to six months is standard. For complex situations with substantial carried interest, cross-border structures, or significant tax planning, six to twelve months allows optimal preparation. Early engagement means better lender matching, cleaner documentation, and stronger negotiating position on rate and terms.
How do private banks treat bonus income differently from high street lenders?
High street lenders typically discount bonuses by 50% and ignore carried interest entirely. Private banks in 2026 can credit 100% of recurring bonuses and carried interest where there is a documented multi-year track record showing consistency and pipeline visibility. The difference in borrowing capacity can be two to three times what a high street bank would offer on the same income.
What is dry lending?
Dry lending is where a private bank provides a mortgage without requiring you to move assets under management to their wealth division. Not all private banks offer this. Some require £1m to £3m in AUM as a condition of lending, while others are comfortable lending on a standalone basis. We identify which banks suit your situation before any approach is made.
Can I borrow through a trust or SPV?
Yes, provided the ownership chain, tax residency, and source of wealth are clearly documented. Private banks and specialist lenders regularly lend to trusts, SPVs, and offshore structures. The documentation and compliance requirements are heavier, but the lending itself is straightforward for an experienced broker to arrange.
