UBP Still Sees Opportunity in Britain as Wealthy Families Move Abroad

Union Bancaire Privée remains interested in acquisitions and regards Britain as an attractive wealth-management market, Financial News reports. Its European wealth-management head, Adrian Künzi, points to families’ continuing property and education connections.

The financing implication extends beyond the question of where wealthy people choose to live. A family can relocate its main residence and move investment management overseas while retaining a London home, rental properties and mortgages in Britain.

For lenders and advisers, that creates a different kind of relationship with the UK. The assets may remain, but the residence, income and banking arrangements supporting them can change. The next refinancing then becomes an international lending question, even where the original mortgage was a straightforward domestic application.

A Significant UK Investment Sits Behind the Outlook

UBP’s recent corporate record gives the discussion substance. Its first-half 2025 results recorded the integration of SG Kleinwort Hambros alongside Société Générale Private Banking Switzerland.

The bank subsequently reported client assets of CHF193.5 billion at the end of June 2026, up 4.8% from the end of 2025. Its first-half 2026 results also described the operational benefits of integrating the acquired businesses.

These figures establish the scale and recent development of the group. They should not be read as a measure of UK mortgage demand or evidence that a particular lending product is available.

Departure Does Not Necessarily Mean Disposal

Much of the practical consequence of relocation depends on what a family retains. Selling every UK asset and repaying every loan produces a different financial position from keeping a home for visits, maintaining a rental portfolio or purchasing accommodation for a child.

That distinction is important when interpreting wealth-migration headlines. A change of residence does not reveal which assets have been sold, which commitments continue or where future financing will be required.

It would be equally misleading to assume that every departing family keeps its property. The relevant point for advisers is that, where ownership continues, the financing needs to reflect the new circumstances rather than the circumstances at the time of purchase.

A British property can remain central to family life without remaining the owner’s main residence. That makes the purpose of the asset an important part of the lending assessment.

The Mortgage Can Become International Before the Property Changes

Consider a hypothetical entrepreneur who relocates from London to Geneva while retaining a £4m London house with a £1.5m mortgage. The family also owns two UK investment properties and holds investments with an overseas wealth manager.

The home’s assumed loan-to-value ratio is 37.5%. There may be substantial equity and considerable wealth elsewhere. Yet a future mortgage application could look materially different from the original one.

A UK salary may have ended. Remuneration might now arrive from an overseas employer or through company distributions. The house may be available for occasional family use, while the household’s principal spending takes place in Switzerland.

The change is not necessarily a deterioration in financial strength. It is a change in how that strength must be evidenced and which lenders can accommodate it.

A lender considering refinancing needs an acceptable basis for servicing and repaying the debt, alongside satisfactory security. The value of the house answers only part of that assessment.

Existing Lending and Future Access Can Diverge

Moving abroad does not automatically mean an existing mortgage must be replaced. The loan terms, lender requirements and planned use of the property determine what needs to happen.

However, the ability to continue an existing loan should not be confused with eligibility to borrow more or obtain a new mortgage. Those are separate decisions.

HSBC’s published intermediary guidance illustrates the distinction: a move to another country after taking a mortgage may affect future additional borrowing. Its non-UK-resident proposition also has specified geographical and application requirements.

For a family considering relocation, the issue may therefore emerge at the next financing event rather than on the departure date. A product switch, an equity release request or a new acquisition can bring the changed circumstances into the lending assessment.

The final maturity of the mortgage is another separate event. An expiring fixed rate raises a pricing question; the end of an interest-only loan raises a capital repayment question. Neither should be lost within broader discussions about banking arrangements.

Income Becomes a Question of Evidence as Well as Amount

The distinction can be particularly important for entrepreneurs. A successful business owner may hold significant company value while drawing a relatively modest salary. After relocation, the mix of salary, dividends and other distributions may change again.

Historic earnings do not necessarily describe the cash available to service the next mortgage. Equally, the estimated value of a business is not automatically accepted as a substitute for recurring income.

The financing assessment needs to establish what will continue, who receives it and how it can be verified. Overseas accounts, personal tax records and bank statements may all be relevant, but the evidence must connect to the proposed repayment arrangement.

Foreign-currency income introduces a further consideration. A sterling mortgage payment can remain unchanged while its cost in the borrower’s income currency rises. Considerable overall wealth does not remove the need to plan for that cash-flow exposure.

This is where selecting a lender solely by headline rate can be unhelpful. The lender first needs to accept the residence, income and transaction. Pricing becomes meaningful within that eligible set of options.

What Happens to the House Matters as Much as Where the Owner Lives

A retained family home, a property let commercially and accommodation occupied by a child can create different lending questions. Describing all three simply as “UK property” overlooks a distinction that can determine the appropriate financing route.

Where a residential borrower intends to let the former home, the existing mortgage conditions and any required lender permission need attention. HSBC’s public guidance, for example, describes consent to let as an arrangement through which it may permit temporary renting.

That is not a universal entitlement or confirmation that a long-term rental plan can remain on the same terms. Permanent letting may require a different assessment and potentially a different mortgage.

Family occupation also needs to be disclosed accurately. Accommodation for a child should not automatically be presented as an ordinary third-party rental investment. Ownership, occupation and the actual arrangements matter to the lender and to the relevant legal and regulatory treatment.

The financing consequence of relocation is therefore not determined by the overseas address alone. It also follows from the decisions made about the property left behind.

The Wealth Manager and Mortgage Provider Need Not Be the Same Institution

The wider private-banking context creates another question: whether property borrowing should sit with the institution managing the family’s investments.

For some clients, an existing private bank may be able to provide a suitable proposal. For others, a separate UK property lender may accommodate the requirement while the investment relationship remains unchanged.

The comparison needs to include any conditions attached to the borrowing. A proposal may depend on transferring investments, maintaining a minimum relationship balance or providing additional security. Those requirements can affect both cost and flexibility.

Assets already committed elsewhere also need to be identified. A portfolio supporting another credit facility cannot simply be assumed to be freely available for a new arrangement.

A lower mortgage rate may be attractive, but the wider terms can determine whether the relationship works for the family. Investment-management costs, liquidity requirements and restrictions on moving assets deserve consideration alongside the property loan.

Willow’s complex property finance work can sit alongside existing private bankers and wealth advisers. The objective is to establish an appropriate borrowing structure, rather than assume the entire financial relationship needs to move.

Relocation Makes Coordination More Valuable

These cases can involve several advisers working from the same family balance sheet for different purposes. A tax adviser considers residence and ownership consequences. An investment adviser assesses liquidity and portfolio commitments. A solicitor addresses legal arrangements. A mortgage adviser assesses lending suitability and availability.

The risk is that each decision appears sensible in isolation while relying on inconsistent assumptions.

A mortgage repayment strategy might depend on investments that are earmarked for another commitment. A property described as available for family use might also appear in a cash-flow plan as a fully let investment. A new borrowing proposal might assume income that is expected to cease after the move.

With the client’s permission, coordination can expose those conflicts before an application or transaction depends on them. It also helps preserve existing relationships where they continue to serve the client well.

Tax residence and lender eligibility remain separate questions. A conclusion reached for one purpose should not be assumed to settle the other.

The Next Refinancing Is Often the Point That Brings the Issue Into Focus

For families already abroad, an approaching product expiry or loan maturity may be the first reason to revisit borrowing arranged years earlier. For those planning to leave, the same dates can influence how the move is financed.

An early review does not necessarily lead to immediate refinancing. Early repayment charges, existing terms and the intended holding period may favour keeping the current loan.

It can nevertheless establish whether the existing lender accepts the future arrangements and what options might be available when a change is needed. That is more useful than assuming a domestic mortgage can simply be renewed on the same basis indefinitely.

Any application should accurately disclose relevant planned changes. Completing a mortgage before departure is not a substitute for explaining a known move, change of income or intended change in property use.

For advisers serving internationally mobile families, retained UK property debt is therefore part of the relocation conversation, even where no purchase is taking place.

The Commercial Story Extends Beyond the Departure Headline

The financing opportunity is not established by counting wealthy departures alone. It depends on the property, debt and family commitments that continue afterwards.

A household may become less straightforward for a conventional domestic mortgage process while remaining financially strong. Another may be best served by retaining its existing arrangement. A third may choose to reduce borrowing rather than reorganise banking relationships to support it.

Those distinctions are where advice becomes valuable. The relevant assessment brings together the family’s present location, continuing UK commitments and future plans, rather than treating relocation as either the end of the relationship with Britain or an automatic reason to refinance.

For Willow, the practical response is to assess UK property finance within that wider international picture—and to work alongside the professionals already advising the family.
