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.

Hyalite Mortgages Remortgage Guide: How to Switch to an Active Lender

This Hyalite Mortgages remortgage guide explains the practical steps for closed-book borrowers to switch to an active lender using a Modified Affordability Assessment or Retirement Interest-Only mortgage.

On Sep 14, 2026

We work regularly with clients who hold an existing Hyalite Mortgages mortgage, so we have a practical understanding of how different lenders approach applications. Hyalite Mortgages is a closed-book administrator, trading as Topaz Finance Limited, and does not offer new mortgage products. Clients on a Hyalite mortgage looking for a better rate therefore need to remortgage with an active lender, typically through a Modified Affordability Assessment (MAA) or another specialist route.

Hyalite Mortgages remortgage guide: Understanding your options

For borrowers administered by Topaz Finance, finding a viable exit from a standard variable rate requires looking beyond the current administrator. When evaluating whether to stay or move, understanding the trade-offs is crucial; our article on product transfers versus new lenders outlines exactly what should be compared before making a decision.

✪ Hyalite Mortgages is a closed-book entity, meaning no new products are available internally.
✪ The primary objective is to secure a like-for-like balance switch to an active lender.
✪ A Modified Affordability Assessment (MAA) is the most common pathway for eligible applicants.

What counts as a viable remortgage from Hyalite?

A viable remortgage in this context means transitioning to a lender that actively underwrites new business and offers competitive fixed or tracker rates. This transition is only feasible if the borrower meets specific baseline criteria set by the new lender.

✪ The outstanding mortgage balance must typically remain the same or decrease.
✪ A clean payment history over the preceding 12 to 24 months is heavily weighted.
✪ The property must not be in negative equity, with most active lenders requiring a maximum loan-to-value of 75% to 80%.

How does the Modified Affordability Assessment work?

The MAA is a streamlined underwriting process designed to help borrowers switch lenders without undergoing a full, rigorous income stress test. It relies on the premise that if a borrower has consistently met their existing mortgage obligations, they are likely to continue doing so.

✪ Lenders focus primarily on the last 12 to 24 months of mortgage statements.
✪ The new mortgage deal must be demonstrably cheaper or offer better stability than the current arrangement.
✪ Borrowers cannot usually increase their borrowing amount under an MAA.

Key steps outlined in this Hyalite Mortgages remortgage guide

Executing a successful switch requires careful preparation and timely submission of evidence to the new lender. For a detailed breakdown of how long this process typically takes, refer to our guide on remortgage timescales.

✪ Gather the last 12 months of mortgage statements and bank statements showing payments.
✪ Obtain a current property valuation to establish the accurate loan-to-value ratio.
✪ Submit proof of identity, address, and any required pension or income evidence.

Worked example: Remortgaging a closed-book mortgage

Consider a borrower with a £150,000 outstanding balance on a Hyalite Mortgages standard variable rate of 6.5%. They have maintained clean payments for the last 24 months, and their property is now valued at £250,000, giving a loan-to-value of 60%. Through an MAA, an active specialist lender may offer a 5-year fixed rate at 4.5%. This reduces the monthly interest cost significantly, and because the balance is not increasing, the affordability check relies primarily on the existing payment history rather than a full stress test of current income.

How does Hyalite compare to alternatives?

When seeking a new lender, it is practical to consider specialist providers that explicitly accommodate borrowers transitioning from closed-book portfolios. These lenders understand the unique constraints of this market segment.

✪ Pepper Money: Frequently considers borrowers transitioning from closed-book lenders, provided there is a clean recent payment history and the LTV is under 75%.
✪ Precise Mortgages: Offers specialist remortgage products that can accommodate complex income profiles or those with historical credit blemishes, as long as the current mortgage is up to date.

Frequently Asked Questions

Can I get a new mortgage product directly from Hyalite Mortgages?

No. Hyalite Mortgages is a closed-book administrator and does not issue new mortgage products or further advances. Borrowers must look to remortgage with an active lender to secure a better rate.

What is a Modified Affordability Assessment (MAA)?

An MAA is a streamlined affordability check used by some active lenders for remortgages. It relies heavily on your existing payment history rather than a full income stress test, provided you are not borrowing more than your current balance.

Do I need a clean credit history to switch from Hyalite?

While a clean recent payment history (typically 12 to 24 months) is crucial for an MAA, some specialist lenders may still consider applications with older, minor credit blemishes if the current mortgage payments are up to date.

Is a valuation required when remortgaging away from Hyalite?

Yes, most active lenders will require a property valuation to confirm the current loan-to-value (LTV) ratio. A lower LTV generally provides access to more competitive interest rates.

Can I borrow more money when I switch lenders?

Borrowing additional funds usually disqualifies you from the streamlined MAA route. If you need to increase your borrowing, you will likely need to pass a full affordability assessment with the new lender.

Are there options for borrowers over 55 with a Hyalite mortgage?

Yes. Borrowers aged 55 and over may be eligible for a Retirement Interest-Only (RIO) mortgage, which assesses affordability based on retirement income and the property’s long-term value.

How long does the remortgage process take?

A straightforward remortgage from a closed-book lender typically takes between 4 to 8 weeks, depending on the speed of the valuation, legal work, and the new lender’s underwriting process.

Why is following a Hyalite Mortgages remortgage guide important?

Understanding your options is the first step to reducing your monthly costs. This Hyalite Mortgages remortgage guide highlights that staying on a standard variable rate indefinitely is rarely the most cost-effective choice, and professional advice can identify viable switching routes.
