For the ultra-wealthy, navigating the world of high-value mortgages can be a complex, yet essential, strategy for wealth accumulation. Leveraging existing assets to secure future fortunes is a cornerstone of (U)HNW financial planning. Given the intricacy of these financial landscapes, the guidance of a trusted debt adviser becomes invaluable.
Securing high-value loans – typically those exceeding £1 million – can be particularly challenging for clients whose assets are tied up in various funds or who lack traditional income streams. In such cases, an experienced adviser, equipped with strong relationships with private banks and specialist lenders, becomes indispensable. Their expertise allows them to tailor bespoke mortgages that align with their clients’ unique financial situations and long-term aspirations.
UHNW debt advisers generally focus on two primary loan types: mortgages and Lombard loans. However, niche offerings such as Sharia-compliant mortgages and bridging loans are also on the rise. Mortgages are secured against the property itself, while Lombard loans, named after the northern Italian region that pioneered modern banking, are backed by assets like stocks, shares or investment portfolios.
While many advisers specialise in real estate, the most experienced also handle a broader spectrum of luxury assets, including yachts and private jets, often facilitating refinancing solutions in these areas as well. Their expertise extends to more niche financing, such as short-term bridging loans, which provide clients with the liquidity needed to ‘bridge the gap’ between acquiring a new property and liquidating assets to fund it.
Trends in 2025
Advisers in this year’s index report that securities-based lending is gaining traction among UHNWs. This type of loan allows clients to use financial securities – such as shares or bonds – as collateral. The appeal lies in the fact that these loans do not require clients to liquidate their investments, offering a more flexible way to access cash. Additionally, because the collateral is highly liquid, interest rates tend to be lower than those of traditional loans, making them particularly attractive in today’s market.
Among the experts shaping the landscape of high-value debt is Daire Dowling of Carrig Private Finance, a new addition to the Spear’s index this year. Specialising primarily in real estate, Dowling is also well-versed in advising on marine and aviation assets. His impressive track record includes securing a £57.5 million mortgage for a villa in France, as well as facilitating high-profile deals such as multiple transactions at the iconic One Hyde Park.
Each adviser on our list brings a unique blend of expertise and strategy tailored to the specific needs of UHNW clients. For example, Tristan Dollie, a partner at Brown Rudnick, offers a more holistic approach. Based at the prestigious US law firm, Dollie goes beyond legal matters, helping clients raise capital while guiding them through the legal nuances of complex financial structures.
As high-value lending continues to evolve, navigating its complexities requires expertise and finesse. For UHNW individuals, having a trusted adviser who understands the art of leveraging assets is essential to ensuring long-term financial success while adapting to an ever-changing global landscape.

Methodology
Each year, the Spear’s Research Unit reassesses and refreshes its rankings of the leading providers in each sector by gathering data from and about the advisers and firms themselves, assessing submission forms, collating nominations, carrying out peer reviews, reviewing data from third-party sources, gathering references and recommendations, canvassing experts and conducting hundreds of interviews.
Advisers are evaluated using a proprietary scoring system that assigns different weightings to certain attributes. These scores feed directly into each new set of rankings in the Spear’s Indices. Each of these indices are published first online (according to the research calendar) and then in print. Print publication takes the form of the annual Spear’s 500 directory, which includes the top advisers in every index.
