Discretionary Fund Management: What Advisers Need to Know

The growing role of discretionary fund management

Discretionary fund management has become one of the most significant trends in UK wealth advice over the past decade. More advisers than ever are outsourcing investment management to specialist DFMs, and the reasons go beyond convenience. Regulatory pressure, rising client expectations, and the sheer complexity of modern portfolio management are driving a structural shift in how advice practices operate.

For advisers who are considering outsourcing for the first time, or reviewing an existing arrangement, understanding how discretionary fund management works in practice is essential.

How discretionary fund management works

At its core, a discretionary fund management service gives an FCA-authorised investment manager the authority to make investment decisions on behalf of clients without seeking approval for each individual trade. The adviser and client agree a mandate that sets out the investment objectives, risk tolerance, time horizon, and any restrictions. The DFM then manages the portfolio within those parameters.

This differs from an advisory service, where the manager proposes trades and waits for consent before acting. The discretionary approach allows faster execution, which matters most during periods of market stress when delays can be costly.

The typical DFM relationship structure

The relationship between adviser, DFM, and client typically follows this pattern:

1. Adviser assesses the client’s needs. Financial planning, risk profiling, and suitability assessment remain the adviser’s responsibility.
2. Adviser selects a DFM. Based on the client’s needs, portfolio size, and the adviser’s own due diligence process.
3. DFM agrees a mandate with the client. This document sets out the investment objectives, asset allocation parameters, risk constraints, and reporting arrangements.
4. DFM manages the portfolio. Day-to-day investment decisions, rebalancing, and trade execution are handled by the DFM’s investment team.
5. Adviser maintains the client relationship. Ongoing planning, regular reviews, and life event management remain with the adviser.
6. Both parties report to the client. The DFM provides investment performance reports; the adviser provides financial planning updates.

Why advisers outsource to a DFM

The decision to outsource investment management is rarely about a single factor. It reflects a broader strategic choice about how an advice practice operates and where the adviser adds most value.

More time for financial planning

Investment management is time-intensive. Researching funds, monitoring markets, rebalancing portfolios, and documenting decisions can consume hours each week. For many advisers, this time would be better spent on financial planning, client meetings, and business development.

A PIMFA ↗ survey found that advisers who outsource investment management to a DFM typically gain 10 to 15 hours per week, which translates directly into capacity for more clients or deeper planning for existing ones.

Specialist expertise

Managing portfolios across multiple asset classes requires deep, constantly updated expertise. A dedicated DFM employs teams of analysts, portfolio managers, and risk specialists who focus exclusively on investment management. This level of resource is difficult for most advice practices to replicate in-house.

For advisers serving HNW clients who need multi-asset class portfolios spanning equities, fixed income, alternatives, and real assets, the case for specialist management is particularly strong.

Regulatory alignment

Under Consumer Duty ↗, advisers must demonstrate that the products and services they recommend deliver good outcomes for clients. Outsourcing to a regulated DFM with documented investment processes, independent risk oversight, and transparent reporting helps evidence this.

The FCA has also signalled that it expects advisers who manage investments in-house to demonstrate the same level of rigour as specialist managers. For smaller practices, meeting this bar is increasingly challenging. As explored in the context of Consumer Duty compliance, the obligation to evidence value and good outcomes applies to every part of the client proposition.

Consistent client outcomes

When an adviser manages portfolios personally, outcomes can vary based on workload, attention, and individual judgement on any given day. A DFM applies a consistent, documented process across all portfolios within the same mandate, reducing the risk of inconsistent treatment between clients.

Types of discretionary fund management service

Not all DFM services are the same. Understanding the spectrum helps advisers match the right service to their client base.

Model portfolio services

At the simplest end, model portfolio services (MPS) provide a set of pre-built portfolios across risk profiles (typically five to ten). Client portfolios are aligned to the appropriate model, and the DFM rebalances all portfolios in that model simultaneously.

Best suited for: Practices with a largely homogeneous client base and investment needs below GBP 500,000 per client.

Limitations: Limited personalisation. Clients with specific exclusions, concentrated positions, or complex tax situations may not be well served.

Bespoke discretionary management

At the other end, bespoke discretionary management builds individual portfolios for each client. The DFM constructs a portfolio tailored to the client’s specific objectives, constraints, tax position, and existing holdings.

Best suited for: HNW and ultra-HNW clients with complex needs, large portfolios, and a requirement for genuine personalisation.

Limitations: Higher cost and typically higher minimum investment thresholds, often GBP 250,000 to GBP 500,000 or more.

Hybrid approaches

Many DFMs offer a middle ground, using model portfolios as a starting point but allowing customisation for individual clients. This might include excluding specific sectors, incorporating existing holdings, or adjusting for tax efficiency.

Service comparison

Feature	Model portfolio service	Hybrid	Bespoke
Personalisation	Low	Moderate	High
Typical minimum	GBP 10,000 to GBP 50,000	GBP 100,000 to GBP 250,000	GBP 250,000+
Cost (DFM fee)	0.15% to 0.30%	0.25% to 0.50%	0.40% to 0.75%
Asset classes	Funds and ETFs	Funds, ETFs, some direct holdings	Full range including direct equities, bonds, alternatives
Tax customisation	None	Limited	Full
Rebalancing	Model-level	Model with client overlays	Individual

Ranges are indicative and vary by provider. Always request a detailed fee schedule.

What to look for in a DFM

Selecting a DFM is a significant decision that deserves structured evaluation. The full framework is covered in our due diligence guide, but the key areas to assess are:

Regulatory standing. Confirm FCA authorisation on the Financial Services Register ↗. Check for any enforcement actions or restrictions.

Investment philosophy and process. The DFM should articulate clearly what they believe, how they construct portfolios, and how they manage risk. Vague or generic answers are a warning sign.

Performance track record. Request composite performance data across risk profiles, measured against stated benchmarks, covering at least three years. Be wary of cherry-picked time periods or benchmarks that are too easy to beat.

Custody arrangements. Where client assets are held matters enormously. Institutional-grade custody provides an additional layer of protection that HNW clients increasingly expect. A DFM using a globally recognised custodian with trillions in administered assets offers a very different level of assurance from one relying on a small, lesser-known platform.

Service quality. Test responsiveness during the evaluation process. If the DFM is slow to respond when trying to win your business, it will not improve afterwards.

Fee transparency. Ask for the total cost, including management fee, underlying fund charges, and custody or platform costs. Under Consumer Duty, you must be able to demonstrate that the overall expense delivers fair value.

The cost of discretionary fund management

Fees are one of the most common concerns for advisers considering a DFM for the first time. Breaking down the total cost helps clients and advisers understand what they are paying for.

Fee layer	Typical range	What it covers
DFM management fee	0.15% to 0.75%	Portfolio management, research, trade execution
Underlying fund charges (OCF)	0.10% to 0.80%	Fund management within the portfolio
Custody/platform fee	0.10% to 0.35%	Holding and safeguarding assets
Total cost	0.35% to 1.90%	All layers combined

The total cost varies enormously based on the service level. A model portfolio service using passive funds with a low-cost platform might deliver a total expense ratio of 0.40%. A bespoke service managing a multi-asset portfolio with institutional custody could cost 1.20% or more, but the complexity and personalisation justify the difference for the right client.

The key question is not “how much does it cost?” but “does the cost deliver fair value relative to the service, outcomes, and alternatives?”

DFM versus in-house investment management

Some advisers prefer to manage investments themselves. This can work well for practices with genuine investment expertise and the infrastructure to support it. But the trade-offs are real.

Factor	In-house management	Outsource to DFM
Time commitment	High (10-15 hours per week)	Low (oversight only)
Specialist expertise	Limited to the adviser’s own knowledge	Full investment team
Regulatory burden	Must demonstrate full investment competence	Shared with regulated DFM
Scalability	Difficult as client numbers grow	Highly scalable
Consistency	Varies with adviser workload	Systematic process
Cost to client	May appear lower, but hidden costs exist	Transparent, disclosed fee
Consumer Duty evidence	Adviser must document everything	DFM provides reporting and evidence

For practices looking to build enterprise value, outsourcing investment management to a DFM is often viewed positively by acquirers. It reduces key person risk, improves consistency, and creates a more scalable business model.

The role of the multi-family office

For advisers serving HNW clients with complex, multi-asset portfolios, a turnkey multi-family office solution takes the DFM concept further. Rather than simply outsourcing portfolio management, the MFO provides the full institutional infrastructure: bespoke portfolio construction, direct market access across asset classes, institutional custody, consolidated reporting, and compliance support.

This model is particularly relevant for advisers who have outgrown their network or whose clients’ needs have moved beyond what a standard DFM model portfolio service can deliver.

Alpha Investment Office, for example, provides a turnkey MFO solution backed by SEI custody (administering over $1.4 trillion globally), with bespoke multi-asset portfolios for clients with GBP 20 million or more. This sits at the institutional end of the discretionary management spectrum, offering capabilities that were previously available only to family offices and institutional investors.

How to transition to a DFM

Moving existing client portfolios to a DFM requires careful planning. A poorly managed transition can erode client confidence and trigger unnecessary tax events.

Key steps

1. Communicate the change. Explain why you are outsourcing and how it benefits the client. Emphasise that you remain their primary adviser and that the DFM brings specialist investment expertise.
2. Review existing holdings. Work with the DFM to assess current positions. Identify holdings that can transfer in-specie (without selling) to avoid unnecessary capital gains.
3. Agree the mandate. Document the investment objectives, risk parameters, and any restrictions or preferences.
4. Phase the transition. For larger portfolios, consider transitioning in stages rather than moving everything at once. This reduces market timing risk and allows the DFM to build positions gradually.
5. Set expectations on reporting. Clients should understand what reports they will receive, how often, and from whom.
6. Schedule a review meeting within three months. An early review reassures the client and gives both you and the DFM an opportunity to confirm the arrangement is working as intended.

Regulatory considerations

Advisers using a DFM should be aware of several regulatory points.

Suitability remains your responsibility. Even though the DFM manages the investments, the suitability of the overall recommendation rests with the adviser. You must ensure the DFM’s service and mandate are appropriate for each client.

Ongoing oversight is required. The FCA expects advisers to monitor DFM arrangements actively. This includes reviewing investment performance, service quality, and continued suitability at least annually.

Consumer Duty applies to the whole chain. Under Consumer Duty, both the adviser and the DFM have obligations. The adviser must ensure the DFM relationship delivers fair value and good outcomes. The DFM must provide the data and reporting needed for the adviser to evidence this.

Documentation matters. Your compliance file should record why you selected the DFM, the due diligence you performed, the mandate agreed, and the results of each periodic review. The FCA ↗ can request this documentation at any time.

The UK DFM market in 2026

The UK DFM market continues to grow. According to The Investment Association ↗, assets managed on a discretionary basis have increased steadily over the past decade, driven by adviser demand and the regulatory environment.

Several trends are shaping the market in 2026:

• Consolidation. Larger DFMs are acquiring smaller ones, reducing the number of providers but increasing the scale and capability of those that remain. This mirrors the broader consolidation trend across the wealth sector.
• Technology investment. DFMs are investing in digital reporting, adviser portals, and API connectivity to make integration with advice practices seamless.
• ESG integration. Most DFMs now offer responsible investment options, though the depth and credibility of ESG integration varies significantly.
• Expanding asset class access. Leading DFMs are broadening their offerings to include private markets, real assets, and structured products, reflecting growing client demand for diversification beyond traditional equities and bonds.
• Fee pressure. Competition is driving model portfolio fees lower, though bespoke and multi-asset services are maintaining pricing due to the complexity involved.

Making the decision

Discretionary fund management is not right for every practice. Advisers with genuine investment expertise, the infrastructure to support it, and a client base that values the adviser’s personal involvement in portfolio decisions may prefer to keep management in-house.

But for the majority of advice practices, outsourcing investment management to a specialist DFM is a strategic decision that improves client outcomes, strengthens compliance, frees up capacity, and builds a more valuable business.

The question is not whether to use a DFM, but which type of service matches your clients’ needs and your practice’s ambitions. Start with the due diligence framework, be rigorous in your evaluation, and choose a partner that enhances, rather than replaces, the value you bring to your clients.
