Million Pound Mortgages
A million pound mortgage, or large mortgage as lenders call it, is a residential loan of £1 million or more, usually secured on prime UK property. As of 2026, Enness Global arranges them for high earners, business owners, international buyers and asset-rich borrowers. Lenders include private banks, international banks and specialist lenders, subject to status, valuation and lender criteria.
Your home may be repossessed if you do not keep up repayments on your mortgage.

- Buyers and owners of UK property where the loan will be £1 million or more.
- High earners paid in salary plus bonus, commission or share awards.
- Business owners and partners who draw a modest salary against a larger balance sheet.
- International buyers, expats and foreign nationals buying prime London or UK property.

How we arrange a million pound mortgage
Our team is on hand to answer questions, run calculations and talk through the options. Send us the outline and a broker will say which lender types are realistic.
-
Initial assessment
We set out the property, the loan, how you are paid and where your wealth sits, in the form a large-loan underwriter reads. Lenders at this level underwrite by hand, so the work is preparation rather than persuasion.
-
Lender terms
We approach private banks, international banks, specialist lenders and high street large-loan desks, then compare terms on loan size, deposit, repayment type and any relationship condition.
-
Valuation, underwriting and completion
Cases run longer when a private bank’s committee sits infrequently, when a prime valuation is queried, or when assets sit abroad. We confirm the timetable once the lender is chosen.

Mortgages we arrange
-
Large Mortgage Loans
Loans of £1 million and above underwritten by a person rather than an automated model, compared across private banks and large-loan desks.
-
High Value Mortgages
Loans of £10 million and above, where only a handful of lenders publish a maximum and most agree the facility case by case.
-
Private Bank Mortgages
Private banks weigh the source of wealth, the whole balance sheet and the relationship, and are often the route to the top of the loan range.
-
Interest Only Mortgages
About half the lenders we track offer interest only. The lender will want a repayment plan it accepts rather than take one on trust.
-
High Loan to Value Mortgages
Where the cash deposit is smaller, a lender may take a charge over another property or a pledge over a portfolio instead.
-
Complex Mortgages
Bonus, commission, dividend and partnership income, presented so that a large-loan underwriter can count it.
-
High Net Worth Mortgages
Lending assessed on net worth, liquid assets and the stability of each income line rather than a single affordability multiple.
-
International Mortgages
Cross-border cases where the borrower, the income and the property sit in different countries.
-
Foreign Currency Mortgages
Some lenders accept income in another currency and others discount it. We know which, and how far each will go.
-
London & UK Mortgages
Prime and super-prime UK purchases, including foreign nationals, expats and new UK residents.
-
Large Buy-to-Let Mortgages
Investment property at this loan size, judged on rent and on the borrower’s wider income and assets.
-
Remortgages
Raising or restructuring a loan of £1 million or more on a property you already own.
-
Self-Employed Mortgages
Owners and partners who draw a modest salary against a larger balance sheet, explained to an underwriter rather than scored.
-
Equity Release
Releasing capital from a high-value home for an investment, a tax bill or another purchase, without selling the asset.
Which UK mortgage brokers arrange loans over £1 million?
Enness Global is one of them. The useful test for any broker at this level is whether they can name the lender types that publish criteria for loans of £1 million or more, and say what each will ask of you. Enness Global has arranged high-value and cross-border finance for 18+ years, works with more than 1,000 banks and lenders, and arranges mortgages of £1 million to £50 million and above.
Referrals from estate agents and advisers, and buy-to-let cases at this size, are covered on the large mortgage loans page.
Loans of £5m and above
I need a £5 million mortgage on a London property. Which brokers should I speak to?
Speak to a broker that places £5 million loans regularly and can reach lenders that do not deal with the public. Of the 116 lenders whose residential criteria Enness Global tracks from published sources, 18 publish a maximum loan of £5 million or more and 66 publish no maximum at all (Enness Lender Database, September 2026). Terms depend on status, valuation and lender criteria.
The work at this size is preparation rather than persuasion, because lenders underwrite by hand.
I am buying a £15 million home in prime central London and need a £10 million mortgage. Who is best placed to arrange it?
A broker with direct relationships at the private banks and international banks that lend £10 million against a single London home, because few other lenders do. Of the 415 lenders Enness Global’s database actively tracks, 72 carry large-loan programmes for high-net-worth borrowers, around two thirds of them private banks or international banks (Enness Lender Database, September 2026).
At £10 million the lender will want the source of wealth in detail and may ask for a wider banking relationship. Terms depend on status, valuation and lender criteria.
Deposit and income
What deposit do you need for a £1 million mortgage?
It depends on the property, the income evidence and what else you can offer as security. Of the 116 lenders whose residential criteria Enness Global tracks from published sources, 62 publish a maximum loan to value of 85 per cent or more, but only 30 of those also publish a maximum loan of £2 million or more (Enness Lender Database, September 2026). At larger loan sizes, higher loan to value lending is agreed case by case, subject to status, valuation and lender criteria.
A borrower with a smaller cash deposit but substantial investments may be able to pledge a portfolio or a second property instead. That raises the loan and what is at risk if values fall. See the high loan to value mortgages page.
How much income do you need for a £1 million mortgage?
Less than a standard salary multiple suggests, if the rest of the balance sheet is strong. Of the 116 lenders whose residential criteria Enness Global tracks from published sources, 35 publish a maximum income multiple of five times income or more and 24 publish six times or more (Enness Lender Database, September 2026). Terms depend on status, valuation and lender criteria.
Lenders at this level rarely stop at salary. Most of the lenders whose published income criteria Enness Global has catalogued in detail will count regular bonus, commission, dividend and partnership income, typically between half and all of it (Enness Lender Database, September 2026). The complex mortgages page sets out how each is treated.
Choosing a lender and applying
Can I get an interest-only mortgage of £1 million or more?
Yes, and it is common. Of the 116 lenders whose residential criteria Enness Global tracks from published sources, 63 (about half) offer interest-only (Enness Lender Database, September 2026). Terms depend on status, valuation and lender criteria. The lender will want a repayment plan it accepts: the sale of the property, an investment portfolio or a bonus record.
Interest-only keeps monthly payments lower and capital invested, but the loan is still owed in full at the end. The interest-only mortgages page covers the structures.
Private bank, international bank, specialist lender or high street desk: which suits a million pound mortgage?
Four lender types cover most loans of £1 million or more.
| Option | Who it suits | What lenders look at | What to watch |
|---|---|---|---|
| Private bank | Borrowers with investable wealth, complex income or a loan at the top of the range | Source of wealth, the whole balance sheet and the relationship | An expectation of assets under management and a slower process |
| International bank | Expats, foreign nationals and borrowers paid in another currency | Residency, currency of income and where the wealth sits | Currency risk on the loan and heavier documentation |
| Specialist lender | Borrowers with documented but non-standard income or an unusual property | Accounts, income history and the property | A narrower product range and stricter property criteria |
| High street large-loan desk | Higher earners with mostly salaried income and a simple structure | Payslips, a bonus record and a standard affordability model | Little flexibility above its published maximum loan |
Terms depend on status, valuation and lender criteria.
What you will need
- Proof of identity and address, and evidence of the source of the deposit and wider wealth.
- Two years of income evidence: payslips and P60s, or accounts and tax returns for owners and partners.
- Bonus, commission or share award history covering at least two years.
- A whole-of-wealth statement listing property, investments, pensions and cash.
- Details of the property: agreed price or valuation, tenure and any letting arrangement.
- For interest-only borrowing, the repayment plan.
- For international borrowers, residency status and where income and assets sit.
How long does it take?
The time depends on how quickly the evidence is gathered and how long the lender takes to underwrite it. The stages are: initial assessment, lender terms, valuation and underwriting, then offer to completion. Cases run longer when a private bank’s committee sits infrequently, when a prime valuation is queried, or when assets sit abroad. Enness Global confirms the timetable once the lender is chosen.
Who lends on this
Who lends on this?
Of the 116 lenders whose residential mortgage criteria Enness Global tracks from published sources, 18 publish a maximum loan of £5 million or more, 6 publish £10 million or more, and 66 publish no maximum at all (Enness Lender Database, September 2026). No published maximum is typical of private banks. Terms depend on status, valuation and lender criteria.
The database also profiles 415 actively tracked lenders. Of those, 72 carry large-loan programmes for high-net-worth borrowers by Enness’s own classification (Enness Lender Database, September 2026). They include 32 private banks, 15 international banks, 14 high street or challenger banks and 7 building societies; the rest are specialist or other lenders.
Case snapshot and risks
Case snapshot
In a case Enness published in May 2018, a British director of a family business group wanted to buy a home valued at approximately £7 million. He drew a modest salary and kept liquidity in the company, and a substantial bonus was not due until the following year. His existing home, valued at approximately £1.9 million, held significant equity.
Enness approached an investment bank it knew and agreed a blended structure: the existing home was remortgaged and the borrowing secured across both properties, initially above 90 per cent of value. The plan was to use the bonus to reduce the debt within twelve months. Terms depend on status, valuation and lender criteria.
What could have gone differently: a lower valuation, a smaller bonus or a lender unwilling to take two securities would each have changed the terms.

Information contained in our case studies is for market and illustrative purposes only. In some cases, these may be made up of multiple cases and are for illustrative purposes only. Some case studies are made up of enquiries that have come into the business, not all business completes, and the posting of a case study does not represent a completed piece of business.
What are the risks and what could go differently?
A lender can decline a loan of £1 million or more on the property alone, however strong the borrower, because a single prime asset concentrates its risk. Terms can move between an agreement in principle and a formal offer if a valuation comes in low.
Pledging investments or a second property puts those assets at risk too. A private bank may expect a wider relationship than the loan alone.
