A private bank mortgage, which clients often call a private banking home loan, is a residential mortgage from a private bank. The bank underwrites the borrower’s whole balance sheet rather than payslips alone. Enness Global arranges them for high-net-worth borrowers, usually from circa £1 million, as of 2026, subject to status, valuation and lender criteria.
Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.
This page is not for salaried borrowers seeking a standard mortgage below about £1 million. The UK mortgages page serves them better.
We build a picture a private banker can read: assets and liabilities, how the income arrives, how the wealth was built and who owns the property. Assessment and lender selection usually take one to two weeks.
We approach UK and international private banks alongside specialist lenders and return indicative terms in one to two weeks, compared on loan size, rate, repayment type and any assets under management condition.
We run onboarding, valuation, underwriting and credit approval, typically three to six weeks, then work to the conveyancing timetable. Most cases complete six to twelve weeks from the first conversation.
Private banks underwrite by hand, and their appetite moves with the balance sheet and country exposure. Enness arranges private bank mortgages for high-net-worth borrowers with complex income, international assets and ownership through trusts or companies, comparing private banks with specialist lenders on the same case.

We are not tied to one bank. We compare UK and international private banks with specialist lenders on the same case, and can exclude any bank that requires assets under management.
A few private banks work with only a small number of brokers, and Enness is in that set. Others refer clients to us when they cannot help, so a case reaches the banks with real appetite for it.
Where a borrower does not want to move a portfolio, we approach only the banks and lenders that will lend without an assets under management condition.
Lending arranged on the whole balance sheet, taking in investment income, business profits, liquidity and assets held outside the UK.
Facilities from private banks, specialist lenders and large-loan desks, compared side by side on loan size, rate and repayment type.
Most private bank lending starts at about £1 million. For loans at that level we set private banks against specialist lenders on the same case.
Bonus, carried interest, dividends, retained profit and trust distributions read differently to every underwriter. Private banks assess them by hand.
Cross-border cases where the borrower, the income and the property sit in different countries, and country exposure shapes which banks will look.
Private banks are often the practical route when income arrives in one currency and the loan is needed in another.
Raising the loan on a home already owned, comparing a private bank against a specialist lender on early repayment charges and any relationship condition.
Private banks will often go further on interest only than a high street lender, provided the repayment plan stands up.
Borrowing against an investment portfolio rather than a property, sometimes alongside a mortgage and sometimes instead of one.
Releasing capital from a high-value home for an investment, a tax bill or another purchase, without selling the asset.
Prime and super-prime UK purchases, including cases where the buyer is a foreign national, a new UK resident or an expat.
Owners and partners whose accounts, drawings and retained profit need explaining to an underwriter rather than scoring by a calculator.
Investment property held personally, through a company or within a wider portfolio, priced against the borrower’s whole position.
A private bank mortgage is a home loan from a bank that serves wealthy clients, underwritten on the borrower’s whole financial position. Loans typically start at about £1 million and run into tens of millions. Private banks can consider complex income, international wealth and ownership through trusts or companies where a high street lender would decline.
Some private banks ask for assets under management as a condition of lending; others lend against the property alone.
Direct or through a broker
Direct works when a borrower already banks privately and the bank has appetite for the property and loan size. A specialist broker earns its place when the borrower does not know which private banks are lending, wants several banks compared side by side, or has been declined. Enness Global compares private banks with specialist lenders on the same case.
Private banks do not publish criteria in the way high street lenders do, and appetite moves with the bank’s balance sheet and country exposure. Some private banks refer clients to Enness Global when they cannot help them.
A whole-of-market broker can. For a remortgage on a London home worth several million pounds where the borrower wants to increase the loan, Enness Global presents the case to private banks and specialist lenders at the same time. Terms are compared on loan size, repayment type, early repayment charges and any relationship condition.
A private bank may offer the larger loan on an interest-only basis but ask for assets to be placed with it. A specialist lender may lend against the property alone with less flexibility. The remortgage page covers the process.
Referrals into Enness
Yes. A wealth manager who wants to keep managing a client’s portfolio can refer the client to a broker who approaches only lenders with no assets under management condition. Enness Global runs this as a standard instruction: banks that require assets to move are excluded, and the wealth manager sees any condition a lender proposes.
The figures under “Who lends on this?” show how common this is. The mortgages without assets under management page explains what these lenders ask for instead.
Yes, and it is a regular route into Enness Global. A private bank may decline a case on country exposure, property type, loan size, an unfamiliar structure or an interest-only limit. The banker keeps the client relationship; Enness Global arranges the mortgage elsewhere and reports back. There are a few private banks who only work with a tiny number of brokers, and Enness Global is in that set.
The referral protects the banker’s relationship, and the mortgage is placed without starting the fact-find again. Bankers who introduce clients work with Enness Global under a written introducer arrangement, described on the introducers page.
How banks assess and compare
Private banks look at the full picture: earned income, investment income, business profits, liquid assets, existing borrowing and the property itself. Where a high street lender applies a fixed income multiple, a private bank forms a view of how the loan will be serviced and repaid.
That flexibility comes with more paperwork, not less: a full statement of assets and liabilities and a source of wealth explanation.
The three lender types most often compared for a large residential loan differ in what they look at and what they ask in return.
| Option | Who it suits | What lenders look at | What to watch |
|---|---|---|---|
| Private bank | Borrowers with complex income or international wealth seeking flexibility | Whole balance sheet, source of wealth, wider relationship | Possible assets under management condition; slower onboarding |
| Specialist lender | Borrowers who want the loan judged on the property and income alone | Income evidence, property, credit history | Less flexibility on structure; tighter interest-only limits |
| High street bank | Salaried borrowers with straightforward income | Payslips, income multiples, credit score | Loan size caps; complex income often excluded |
Terms depend on status, valuation and lender criteria.
Preparing an application
A private bank mortgage usually takes six to twelve weeks from first conversation to completion. Initial assessment and lender selection take one to two weeks, indicative terms one to two weeks more, and valuation, underwriting and credit approval three to six weeks. Offer to completion then follows the conveyancing timetable. New-client onboarding, cross-border documents and trust or company structures are the usual reasons it takes longer.
Enness Global’s lender database profiles 415 actively tracked lenders. Of those, 36 are private banks or securities-backed lenders by Enness’s own classification (Enness Lender Database, September 2026). Of the 116 lenders whose residential criteria Enness Global tracks from published sources, 75 (around two thirds) lend without requiring assets under management (Enness Lender Database, September 2026). Terms depend on status, valuation and lender criteria. They include 24 building societies, 20 high street or challenger banks, 13 international banks and 5 specialist buy-to-let lenders; the remaining 13 are specialist or other lenders.
Evidence, cases and risks
Clients come to a private bank for lending the high street will not give them: a higher loan to value, a proper understanding of their income and assets, and flexibility on international income or other assets. Private banks are not always the right solution, they can be more expensive and may want assets under management, but for the right customer they bring speed, service and lending tailored to the circumstances.

What could have gone differently: a second home at high loan-to-value narrows the lender pool sharply. Slow onboarding would have put the off-market purchase at risk. Read the £10 million private bank facility case study. A second published case is a private bank mortgage at approximately 90 per cent loan-to-value on a prime home.
Private banks decline cases as well as approve them, most often on country exposure, property type or structure. Terms can change between indicative offer and credit approval if the valuation comes in low or the source of wealth needs more evidence.
An assets under management condition ties part of the portfolio to the lender for the life of the loan. Interest-only borrowing needs a credible repayment plan that the bank will test. Any mortgage puts the property at risk if repayments are not kept up.
Private banks are often the route to a £5 million mortgage on a prime London home.
Answers from our specialist brokers to the questions we are asked most often about private bank mortgages.
Let's talk nowNot reliably. Private banks price each case individually, and pricing depends on the borrower’s profile, the loan size and any wider relationship. Their advantage is usually structure and flexibility rather than headline cost. A broker compares private bank terms with specialist lenders so the borrower can weigh cost against flexibility for the case in hand.
