The decision that shapes your proposition
When a wealth adviser decides how to manage client portfolios, the choice between a discretionary and an advisory approach is not a technical detail. It determines who holds decision-making authority, how quickly portfolios respond to market events, how fees are structured, and ultimately how your practice operates.
The UK market has moved decisively towards discretionary management over the past decade, but advisory mandates still have their place. Understanding where the line sits, and why it matters for your clients and your practice, is essential before settling on an approach.
How discretionary management works
Under a discretionary mandate, the investment manager has delegated authority to make buy and sell decisions within an agreed framework. That framework typically covers the client’s risk profile, time horizon, investment objectives, any ethical preferences, and specific exclusions.
Once the mandate is in place, the manager executes trades without needing to seek approval for each transaction. This is what makes discretionary management efficient at scale. It also means the portfolio can respond to market events, macro shifts, or tax planning opportunities in hours rather than weeks.
For advisers, the practical benefit is clear. You focus on financial planning, relationship management, and practice growth, while a specialist discretionary fund manager handles the portfolio.
Key features of discretionary management
- Delegated authority. The manager acts within agreed parameters without requiring consent for individual trades.
- Faster execution. Trades happen when the manager decides, not when the client responds.
- Standardised documentation. The mandate, investment policy statement, and reporting are set up once and then reviewed periodically.
- Easier to scale. Advisers can serve more clients because investment decisions are outsourced.
How advisory management works
Under an advisory mandate, the investment manager researches, analyses, and recommends, but the client or adviser must approve each trade before execution. The client retains control over every decision, and the manager acts as an expert consultant rather than a delegated decision-maker.
In practice, this means a flow of recommendations, usually formalised in writing, followed by client instructions to proceed (or not). The manager cannot act unilaterally, even if markets move sharply between the recommendation and the response.
This model suits clients who want to stay involved at a granular level, or who have specific preferences that are difficult to codify in a standing mandate.
Key features of advisory management
- Client retains authority. Every trade requires explicit approval before execution.
- Slower response. The time between recommendation and action can be hours or days.
- Detailed documentation per trade. Each recommendation, response, and rationale needs recording.
- Higher adviser time cost. Advisers spend more time on each client’s portfolio, limiting scalability.

Why the UK market has moved towards discretionary
Industry data from the Investment Association and the Personal Finance Society consistently shows that discretionary mandates now dominate the UK wealth management landscape. Several forces explain the shift.
Regulatory pressure
Consumer Duty places a firm obligation on advisers to deliver good outcomes. Discretionary management creates a cleaner evidence trail: an agreed mandate, documented process, and periodic review. Advisory mandates require per-trade documentation, which is workable but administratively heavier.
For many advice practices, the cost of running a fully compliant advisory operation has become prohibitive once you account for adviser time, compliance oversight, and the risk of documentation gaps.
Speed of execution
Markets no longer wait for weekly client calls. A discretionary manager can act on a macro event within hours. An advisory mandate cannot, and in volatile conditions, delay can cost clients real money.
For HNW portfolios with complex tax positions, this timing issue extends beyond market movements to include CGT harvesting, bond maturity reinvestment, and rebalancing around fiscal events such as the new tax year.
Client preference
Most HNW clients do not want to approve every trade. They want to know their portfolio is being managed professionally and that their adviser is overseeing the relationship. What HNW clients actually value is strategic counsel, not transaction-level involvement.
Practice economics
Running an advisory book caps the number of clients a single adviser can serve. Discretionary outsourcing to a specialist manager frees adviser time for planning, relationships, and building enterprise value.
When advisory management still makes sense
Despite the clear trend, advisory mandates are not obsolete. There are circumstances where they remain the right choice.
Concentrated single-stock positions. A client with a legacy shareholding they are emotionally attached to, or that carries significant unrealised gains, may want to retain final say over any sale.
Highly personalised ethical constraints. If a client has a detailed set of exclusions that cannot easily be captured in a discretionary mandate, advisory management offers a way to review each decision through that lens.
Clients who value involvement. A minority of HNW clients, often those from trading or business backgrounds, genuinely enjoy the investment process and want to participate at the trade level.
Transition arrangements. Where a client is moving from self-directed investing to delegated management, an advisory period can act as a bridge, allowing them to build confidence in the manager before switching to full discretion.
Consumer Duty implications
The regulator does not prescribe one model over the other. Both discretionary and advisory management can deliver good client outcomes, provided the right governance is in place.
For discretionary mandates
- Clear investment policy statement aligned to the client’s risk profile and objectives
- Regular reporting, typically quarterly, with annual review meetings
- Documented monitoring of the manager’s performance against benchmarks
- Evidence of ongoing suitability and fair value assessments
For advisory mandates
- Written recommendation for each trade, with supporting rationale
- Timely client response, with records of approval or rejection
- Trade execution documentation showing the decision chain
- Periodic review showing outcomes across the client’s portfolio
The key for Consumer Duty is not which model you use, but whether you can demonstrate that the chosen approach delivers fair value and good outcomes for each client. The advice guidance boundary review may reshape this landscape further, so practices should expect continued regulatory attention in this area.
Fee transparency
Fee structures differ meaningfully between the two models, and clients should understand the total cost of each.
Discretionary fees are typically tiered by portfolio size. A portfolio of GBP 500,000 might pay 0.50% per year, while a GBP 5 million portfolio might negotiate down to 0.20% or lower. These are management fees only; underlying fund charges and custody fees are additional.
Advisory fees are often quoted at a higher headline rate, reflecting the bespoke nature of the recommendations. However, the true cost includes the adviser’s time spent reviewing and executing each recommendation, which can materially increase the total burden on the client.
For a comprehensive view, always ask for a total cost breakdown including the manager’s fee, any advisory overlay, underlying fund charges, custody fees, and transaction costs.
How this connects to your platform choice
The practical delivery of discretionary or advisory management depends heavily on the platform and custody infrastructure supporting it. Choosing the right platform determines how smoothly mandates are executed, how transparent reporting is, and how efficiently trades are settled.
Institutional-grade custody, such as that provided by SEI Investments, adds another layer of confidence. For HNW clients in particular, the role of institutional custody in establishing trust should not be underestimated.
Making the call
For most UK advice practices serving HNW clients, discretionary management is the default answer. It scales, it documents cleanly, and it meets client expectations of a professionally run portfolio.
Advisory management remains valuable for specific client segments and situations, but it is increasingly a niche offering rather than a default proposition.
The decision should not be driven by nostalgia for how investment management used to work, nor by habit. It should be driven by a clear-eyed assessment of what each model delivers, what it costs in total, and what your clients actually need from you.
If your proposition still defaults to advisory mandates, it may be time to review whether that reflects current client needs, regulatory expectations, and the economics of running a modern advice practice. For many firms, the answer points firmly in one direction.
Frequently Asked Questions
What is the difference between discretionary and advisory management?
Under a discretionary mandate, the investment manager makes buy and sell decisions on the client's behalf within an agreed strategy, without needing approval for each trade. Under an advisory mandate, the manager recommends trades but cannot execute them until the client or adviser gives explicit consent. The key distinction is where decision-making authority sits.
Which is more expensive, discretionary or advisory management?
Discretionary management is typically cheaper on a per-client basis because it scales efficiently. Fees usually range from 0.15% to 0.75% of assets under management. Advisory management often costs more in real terms once you factor in adviser time spent reviewing and approving each recommendation, even if headline fees appear lower.
Is discretionary or advisory management better for HNW clients?
Discretionary management is generally more suitable for HNW clients with diversified portfolios where speed of execution, tax efficiency, and professional oversight are priorities. Advisory management can work for clients who want to retain control of every decision, but this is a diminishing minority and often creates friction during volatile markets.
Does advisory management still have a place in UK wealth management?
Yes, but its role has narrowed. Advisory mandates remain relevant for clients with unusual preferences, specific ethical constraints, or concentrated positions they want to manage themselves. However, the operational cost and Consumer Duty documentation burden mean most advice practices now default to discretionary for the core of their client base.
How does Consumer Duty affect the choice between discretionary and advisory?
Consumer Duty requires advisers to demonstrate that clients receive fair value and good outcomes. Discretionary management generally provides stronger evidence of professional oversight, consistent process, and timely action. Advisory mandates require more robust documentation of each recommendation, client response, and rationale, which increases administrative burden.
