Managing £5m+ After a Business Exit: Private Banks vs Self-Directed Investing

Receiving a large liquidity event after a business sale raises a fundamental question: should wealth be actively managed by a private bank, or handled through a simpler, self-directed strategy? While the decision often appears to be about convenience versus cost, it is more accurately a trade-off between control, complexity, long-term returns, and personal priorities.

The Role of Private Banks in Wealth Management

Private banks typically offer a bundled service that includes portfolio management, tax structuring, estate planning, and access to alternative investments. For individuals with limited time or interest in managing capital, this can reduce the operational burden of wealth oversight.

In addition to investment selection, private banks may incorporate elements such as trust structures, cross-border planning, and currency management. These features can be relevant for individuals with complex financial lives or international exposure.

However, the value of these services depends heavily on whether the client actually needs that level of complexity. For relatively straightforward financial situations, the benefits may be less pronounced.

How Fees Affect Long-Term Outcomes

One of the most debated aspects of private banking is cost. Annual fees often range around 0.5% to 1% of assets under management, sometimes higher when layered with underlying product costs.

While this may appear modest on an annual basis, the long-term impact can be significant due to compounding. Over decades, even a 1% annual fee can reduce total portfolio value by a substantial margin.

Factor Low-Cost Approach Private Banking Approach
Annual Fees ~0.1%–0.3% ~0.5%–1%+
Control High Delegated
Complexity Handling Limited Comprehensive

This trade-off becomes particularly relevant when withdrawal rates are relatively low, such as in early retirement scenarios.

The Appeal of a Self-Managed Portfolio

A common alternative is a self-directed portfolio built around globally diversified index funds. This approach emphasizes simplicity, transparency, and cost efficiency.

Many individuals adopt a “world equity tracker plus bonds” structure, allowing them to participate in global market growth without active stock selection. Rebalancing can be done periodically with minimal time commitment.

  • Broad diversification across global markets
  • Low fees and minimal ongoing maintenance
  • Clear understanding of portfolio composition

This approach assumes a willingness to tolerate market volatility and maintain discipline during downturns.

Tax, Structuring, and Professional Advice

Even for those who prefer a self-managed investment strategy, professional advice can still play an important role. Areas such as capital gains tax planning, inheritance tax mitigation, and trust structures often require specialized expertise.

Rather than delegating full portfolio control, some individuals choose to engage advisors on a one-off or periodic basis. This hybrid model separates strategic advice from ongoing asset management fees.

In practice, this may involve working with chartered financial planners or tax specialists while maintaining direct control over investments.

Balancing Risk, Income, and Simplicity

Generating income from a £5m+ portfolio does not necessarily require complex products. A combination of equities, bonds, and withdrawal strategies can often achieve similar outcomes with greater transparency.

At the same time, private banks may offer structured products, private equity access, or tailored income solutions. These can diversify return sources, but they also introduce additional layers of risk and reduced liquidity.

The key question is not whether one approach is superior, but whether it aligns with the investor’s risk tolerance, time availability, and desired level of involvement.

A Practical Framework for Decision-Making

Choosing between private banking and self-management can be approached through a few guiding considerations:

  • How much time and interest is available for managing investments?
  • Is the financial situation structurally complex or relatively straightforward?
  • What level of fee drag is acceptable over the long term?
  • Is access to alternative investments genuinely valuable or unnecessary?

In some cases, individuals begin with a private bank and later transition to a simpler structure as confidence and clarity increase. Others take the opposite path, seeking professional support as wealth grows more complex.

There is no universally optimal solution, only a balance between cost, convenience, and control that fits the individual context.

It is important to note that any strategy should be considered within the broader financial environment, including tax obligations, liquidity needs, and long-term lifestyle goals. Outcomes can vary significantly depending on assumptions about returns, inflation, and personal spending.
