Do I need to bank with a private bank already to get a private bank mortgage?

No, though it helps. Most private banks will consider a mortgage as the opening of a new relationship, not just a product for existing clients. Some, like C.Hoare & Co, are the exception and lend almost exclusively to existing private clients.

How much do I need in assets to qualify for a private bank mortgage?

There's no single threshold — it varies by bank and by case. Some banks expect a meaningful level of assets under management as a condition of lending; others are more flexible if the income and security profile is strong.

Is a private bank mortgage cheaper than a high street mortgage?

Not necessarily. Rates can be competitive, particularly for clients bringing significant assets to the relationship, but arrangement fees and AUM requirements often offset any headline saving. The right comparison depends on the full structure, not just the rate.

Can I get a private bank mortgage as a non-UK resident?

Yes — international and non-resident clients are a core part of the private banking mortgage market, particularly for prime London property. Structuring across jurisdictions and currencies is something private banks are typically well set up to handle.

What's the minimum loan size for a private bank mortgage?

Most private banks focus on loans from around £1-2 million upwards, though this varies by lender and by the wider relationship. Below this level, high street or specialist lending is usually more appropriate.

Can I use investment assets instead of income to secure a mortgage?

Often, yes. Many private banks will lend against a discounted value of a portfolio rather than requiring income alone to support the loan, which is particularly useful for clients with significant wealth but modest salaried income.

Do private banks offer interest-only mortgages?

Yes, more readily than most high street lenders, particularly where there's a credible and evidenced repayment strategy tied to assets, business sale proceeds, or other capital events.

How long does a private bank mortgage take to arrange?

It varies considerably. Because terms are relationship-led rather than templated, timelines can be longer than a straightforward high street application, though a well-prepared case presented to the right bank can still move quickly.

What documents will a private bank ask for?

Expect more than a standard mortgage application — typically a detailed statement of assets and liabilities, business accounts or tax returns for variable income, source of funds and source of wealth evidence, and details of any existing banking relationships.

Can a private bank mortgage be used for buy-to-let or commercial property?

Some private banks will lend on investment or commercial property as part of a wider relationship, though this is less standardised than residential lending and is assessed case by case.

What happens if my income is irregular or made up of bonuses and dividends?

Variable income is typically assessed holistically rather than through a fixed multiplier, which suits business owners, partners, and bonus-heavy earners.

Should I use a broker or approach a private bank directly?

A broker with active private banking relationships will usually have a clearer view of current lending appetite than a client approaching cold, and can present the case to the bank most likely to say yes on the best terms.

Is a private bank mortgage right for every high-net-worth borrower?

No. For a straightforward purchase with clean, provable income and no interest in a new banking relationship, a high street lender is often faster and cheaper. Private bank lending earns its place where complexity, scale, or an existing relationship make it worthwhile.

Can an HSBC Mortgage Through a Broker Be a Better Fit?

An HSBC mortgage through a broker involves adviser-led assessment and submission through HSBC’s intermediary platform. This guide covers affordability, income evidence, processing and alternatives.

Written By: James Blackler

On Aug 28, 2026

At Oakstead Finance, we work with HSBC regularly and have a practical understanding of how the lender approaches applications. HSBC accepts mortgage applications through registered intermediaries as well as through its direct channels, with broker cases submitted and managed through its intermediary platform.

How Does an HSBC Mortgage Through a Broker Work?

An HSBC mortgage through a broker begins with an assessment of the applicant’s circumstances before the broker submits a Decision in Principle and, where appropriate, a full application.

✪ The broker checks HSBC’s criteria, affordability and available intermediary products.
✪ HSBC states that its Decision in Principle can take around 15 minutes to complete.
✪ Information from the Decision in Principle is carried into the full mortgage application.
✪ HSBC makes the lending decision and may request further evidence through the broker.

How Much Can HSBC Lend Through a Broker?

HSBC’s published income multiples provide maximum boundaries, while its affordability assessment determines the amount available for the individual application.

✪ At no more than 85% loan-to-value, the published maximum is 4.49 times income where salary is below £45,000.
✪ The published maximum rises to five times income from £45,000 to below £100,000.
✪ Income of £100,000 or more may support a maximum of 5.5 times income.
✪ HSBC publishes a minimum mortgage of £10,000, a minimum property value of £50,000 and no general maximum loan amount.

Debts, dependants, household expenditure, mortgage term and credit history can reduce the result. Oakstead Finance explains what lenders assess alongside income multiples.

How Does HSBC Assess Bonus, Commission and Company Income?

HSBC can consider regular variable income, but the amount used and the evidence required depend on the income type and payment frequency.

✪ HSBC states that up to 60% of the two-year average of regular bonus, overtime and commission may be used.
✪ Its published guidance separately states that a maximum of 50% of average overtime can be treated as guaranteed income.
✪ For limited-company directors, HSBC may use salary plus the applicant’s share of average net profit after corporation tax.
✪ HSBC states that dividends are not used as self-employed income under this calculation.

Self-employed applicants may need finalised accounts, tax calculations and tax-year overviews. Oakstead Finance explains how to obtain SA302s and tax-year overviews.

What Does a Broker Need to Submit to HSBC?

Accurate application data and correctly packaged evidence are central to avoiding preventable HSBC underwriting queries.

✪ Employed applicants normally need their latest payslip dated within 35 days.
✪ Variable income requires the documents specified in HSBC’s evidential matrix.
✪ The applicant’s legal name, address and employer details must match the supporting documents.
✪ HSBC may cancel an application when all required documents have not been received within 30 days of submission.

The affordability indication is not an offer and can change after evidence, valuation and full underwriting. Oakstead Finance examines this distinction in The Mortgage Figure an Online Calculator Cannot Confirm.

HSBC at a Glance

General maximum mortgage	No published maximum

What Could an HSBC Mortgage Through a Broker Look Like?

An HSBC mortgage through a broker can be illustrated using a hypothetical applicant earning a basic salary of £80,000 who wants to buy a £500,000 home with a £125,000 deposit.

The requested mortgage is £375,000, producing a 75% loan-to-value. At this income level and loan-to-value, HSBC publishes a maximum income multiple of five times, creating a theoretical ceiling of £400,000.

The £375,000 request sits £25,000 below that ceiling. It does not follow that HSBC would lend £375,000: childcare, loans, credit-card balances, service charges, the mortgage term and HSBC’s affordability model could produce a lower result.

How Long Can an HSBC Broker Application Take?

HSBC currently lists an assessment time of around two working days for specified residential accept and provisional-accept cases, but this is not a promised completion time.

✪ HSBC says a broker Decision in Principle takes approximately 15 minutes to complete.
✪ The lender says the remaining full-application form can take approximately five minutes to complete.
✪ Remortgage offers may be produced within 48 hours in some cases, depending on the valuation outcome.
✪ Document checks, underwriting, valuation and conveyancing can extend the overall timeframe.

How Does an HSBC Mortgage Through a Broker Compare With Alternatives?

An HSBC mortgage through a broker can be compared with Accord Mortgages and NatWest where access or variable-income policy materially changes the assessment.

✪ Accord is an intermediary-focused lender and publishes acceptance of 60% of sustainable bonus, overtime and commission, subject to its cap against basic income.
✪ NatWest publishes acceptance of up to 100% of evidenced regular monthly bonus and commission, while annual discretionary bonus is generally limited to 50%.

Neither distinction makes one lender universally stronger. Product cost, usable income, affordability, evidence and property criteria need to be compared together.

What You Need to Know

In practical terms, an HSBC mortgage through a broker combines HSBC’s current lending policy with an adviser-led assessment, submission and case-management process.

✪ HSBC remains responsible for every lending decision.
✪ Published income multiples are maximum limits, not guaranteed borrowing figures.
✪ Accurate application data and complete evidence can prevent avoidable delays.
✪ Criteria, products and service levels can change and require confirmation before submission.
