Stonehage Fleming: who are they?
Stonehage Fleming traces its roots back to 1873, when Robert Fleming founded the merchant bank that would go on to become Fleming Family & Partners.
Its Stonehage side began in 1976, originally set up to help South African families manage wealth held outside the country.
The two businesses merged in 2014 to form Stonehage Fleming, a multi-family office serving wealthy families, entrepreneurs, and institutions.
For most of its recent history, Stonehage Fleming has been independently owned by management and staff, alongside a publicly listed family investment trust.
That changed in 2025, when the Stonehage Fleming Group was acquired by Corient, a US wealth management consolidator. The Stonehage Fleming brand, people, and offices continue much as before, but it's worth knowing the firm is no longer independently owned.
Stonehage Fleming manage and advise on more than $75 billion (around £55 billion) for private individuals, family offices, trustees, charities, and endowments.

What does Stonehage Fleming do?
Stonehage Fleming Investment Management builds and runs investment portfolios for wealthy families and their advisers, rather than selling products directly to the mass market. Its work falls broadly into three areas.
The first is discretionary and advisory portfolio management, constructing and running bespoke portfolios of shares, bonds, funds, and alternative assets on behalf of individual clients, trusts, and institutions, either with full discretion or working alongside the client's own decisions.
The second is running a range of pooled investment strategies and funds, including its flagship Global Best Ideas Equity strategy, multi-asset portfolios, thematic and responsible investment funds, and access to private markets.
The third is a retail-accessible fund range, the TM Stonehage Fleming Investments Funds, sold through mainstream platforms such as Hargreaves Lansdown, so investors who don't meet the firm's direct client thresholds can still access some of its strategies via an ISA, SIPP, or general investment account.
Its direct discretionary and advisory service is aimed at professional clients, eligible counterparties, sophisticated investors, and certified high-net-worth individuals, rather than everyday savers.
What are the pros and cons of Stonehage Fleming?
Like any investment management firm, Stonehage Fleming has its strengths and weaknesses.
The pros of Stonehage Fleming:
Long standing heritage in managing wealth for families and institutions, combining the Fleming merchant banking lineage with Stonehage's decades of family office experience
International investment teams, spanning London, Zurich, Liechtenstein, Cape Town, Johannesburg, and Jersey, which can suit families with cross-border assets or interests
A broad range of strategies under one roof, multi-asset, global equities, thematic, cash and fixed income, private capital, and responsible investment, reducing the need to use multiple managers
A retail accessible route via the TM Stonehage Fleming OEIC fund range, held through platforms like Hargreaves Lansdown, for investors who can't meet the direct client thresholds
Client assets are held with established external custodians (rather than the firm itself), adding a layer of separation between client money and the firm's own balance sheet
The cons of Stonehage Fleming:
Not designed for ordinary retail investors, the direct discretionary and advisory service is explicitly restricted to professional, sophisticated, or certified high-net-worth clients
Recently changed ownership, the 2025 Corient acquisition ended decades of independent, management-owned status, which some long standing clients may view as a material shift
Fees for direct discretionary and advisory mandates aren't published; prospective clients need to enquire and negotiate rather than compare costs upfront
Fund charges on the retail-accessible range (initial charges of up to 5%, ongoing charges approaching 1% on some share classes) sit above the lowest cost options available elsewhere in the market
Family office and wealth planning services (pensions, trusts, tax) sit with separate legal entities from the investment management business, which can make it harder to understand exactly who you're contracting with
What services do Stonehage Fleming offer?
Stonehage Fleming Investment Management's core offering centres on portfolio construction and fund management, built around a small number of investment capabilities.
These include:
Discretionary portfolio management, where the firm makes day-to-day investment decisions within agreed guidelines
Non-discretionary (advisory) portfolio management, where the client retains the final say on transactions
Multi-asset portfolios, including the Global Sustainable Investment Portfolios, which apply socially responsible criteria alongside standard risk and return objectives
Global equities strategies, most notably the Global Best Ideas Equity Fund, a concentrated portfolio of quality businesses
Thematic investing through the Global Thematic Investor Portfolios, targeting long-term structural trends
Cash and fixed income strategies for capital preservation and income
Private capital and private markets access, including the Global Private Capital Fund, for investors able to meet the higher risk and liquidity requirements involved
A range of retail-accessible OEIC funds (the TM Stonehage Fleming range), available through platforms and holdable in an ISA, SIPP, or investment account
What fees does Stonehage Fleming charge?
Stonehage Fleming doesn't publish a single fee card, because charges depend on the size of the mandate, the strategy used, and whether you're a direct discretionary client or investing via a fund.
Here's what is publicly available:

"It can be daunting paying for financial advice, but it should add more value than it costs – and benefit you in the long term.
For example, optimising your pension strategy so you have a fund with lower fees and a track record of strong performance could pay dividends when you retire, although there are no guarantees.
There are other benefits as many people who received financial advice have a clearer understanding of their money goals, more confidence in retirement planning and experience lower financial stress.”

What technology does Stonehage Fleming use?
Stonehage Fleming has invested in digital tools to support client reporting, onboarding, and day-to-day account access.
A client portal for viewing investment portfolios, alongside a separate wealth planning portal for financial planning clients
A collaborative client hub built on Moxo's workflow software, giving clients and teams a single, secure space to communicate and exchange documents, with encryption and access controls built in
Laserfiche, a content management and process automation platform used across the wider group's offices to handle onboarding and back-office processes; this work won Stonehage Fleming a Datos Insights 2024 award for technology transformation in digital wealth management
Stonehage Fleming security: is it secure?
Security for a firm like Stonehage Fleming operates on several levels, regulatory oversight, how client money is held, and the technology protecting client data.
The UK investment management business is authorised and regulated by the FCA (reference 194382)
Client assets are held with external, regulated custodians
If an FCA-authorised investment firm fails, eligible claims are covered by the Financial Services Compensation Scheme (FSCS) up to £85,000 per person, per firm
The client portal uses encryption and access controls, according to the technology partner's published case study
Does Stonehage Fleming have good customer service?
Stonehage Fleming operates a relationship led, high touch model typical of family offices, built around named contacts and dedicated client teams rather than call centres or live chat.
That fits its client base, who tend to have complex, multi-generational needs rather than simple, transactional queries.
Because the firm serves a relatively small number of large clients rather than a mass retail audience, there isn't the same volume of independent customer reviews or star ratings you'd find for a mainstream bank or investment platform, which makes it harder to judge service quality from the outside.
Anyone considering the firm should ask directly about response times, how often you'll hear from your relationship manager, and what happens if your usual contact leaves, and, where possible, speak to existing clients or an independent adviser who has dealt with the firm before making a decision.
Final verdict: is Stonehage Fleming right for you?
Stonehage Fleming is a well-established, internationally minded investment manager with genuine depth in serving wealthy families, family offices, and institutions.
If you have significant assets, complex needs, and want services under one roof, it's a firm worth considering, particularly if you already work with an adviser who can help you assess the fit.
It's less suited to everyday investors. The firm is explicit that its direct investment management service isn't for ordinary retail clients and its fees for bespoke services aren't published upfront.
