DFM Charges Explained: A Guide for UK Wealth Advisers

Why DFM charges deserve more attention in 2026

Under Consumer Duty, fair value is not a marketing slogan. It is a documented regulatory obligation, and fees sit at the heart of it. Advisers recommending a discretionary fund manager are expected to evidence that the total cost to the client is proportionate to the benefits received, and that the client understands what they are paying for.

In practice, that means going beyond the DFM’s headline management fee. Two providers quoting 0.30% may differ by 50 basis points once underlying fund charges, custody, VAT, and transaction costs are included. For a GBP 1 million portfolio, 50 basis points is GBP 5,000 a year of difference. Over a decade, that compounds into a meaningful drag on outcomes.

This article breaks down how DFM charges actually work, where the hidden layers live, and what advisers should demand from providers to meet both Consumer Duty and their own fair-value expectations.

The four layers of DFM cost

A DFM arrangement typically involves four separate charges. Not all providers disclose them with equal clarity, which is the problem.

Layer	Typical range	What it pays for
DFM management fee	0.15% to 0.75% p.a.	Portfolio construction, research, rebalancing, reporting
Underlying fund charges (OCF)	0.10% to 0.80% p.a.	The expense of funds held within the portfolio
Custody/platform fee	0.10% to 0.35% p.a.	Holding and safeguarding assets, settlement, corporate actions
Transaction costs	0.05% to 0.25% p.a.	Dealing costs, spreads, stamp duty

Adding these together gives the total expense ratio for the client. It typically sits somewhere between 0.35% and 1.90% a year depending on the service type. VAT then applies to the DFM management fee in most cases, adding another 20% on top of that single layer.

Layer 1: the DFM management fee

This is the most visible cost and the one most often quoted. It covers the DFM’s work: investment research, portfolio construction, asset allocation, rebalancing decisions, and reporting to the client.

Headline ranges in the UK market today:

• Model portfolio services (MPS): 0.15% to 0.30%
• Hybrid or customised MPS: 0.25% to 0.50%
• Bespoke discretionary: 0.40% to 0.75%, sometimes higher for family-office-style mandates

Most DFMs publish tiered pricing with breakpoints at GBP 250k, GBP 500k, GBP 1m, GBP 5m, and GBP 10m. Ask for the tier schedule rather than a single number; a client with GBP 1.2m pays a blended rate, not the top-band rate.

Layer 2: underlying fund charges (OCF)

If the DFM invests through collective funds (OEICs, unit trusts, ETFs, investment trusts), each fund has its own Ongoing Charges Figure. The client pays this on top of the DFM’s management fee.

Passive fund OCFs typically range from 0.05% to 0.25%. Active funds range from 0.50% to 1.00%, with specialist or alternative funds sometimes higher. A DFM’s blended portfolio OCF often sits in the 0.10% to 0.50% range depending on the balance of active and passive.

This is where two DFMs with identical headline fees can diverge sharply. A passive-heavy portfolio running at 0.15% OCF looks very different from an active-heavy portfolio at 0.65% OCF, even if both DFMs charge the same 0.30% management fee.

Note also that underlying fund charges have their own embedded costs: transaction costs inside the funds, platform rebates (rare in 2026 post-RDR), and manager incentive fees on alternatives. These do not appear in the OCF but do appear in the total cost of ownership.

Layer 3: custody and platform fees

Somebody has to hold the assets. Custody arrangements vary significantly:

• Retail platforms (Transact, Quilter, AJ Bell, Fidelity): often 0.15% to 0.35% on the first slices, tiered down at higher balances. Clean, transparent, but designed for retail rather than HNW needs.
• Wrap platforms operated by the DFM: charges embedded or broken out, sometimes labelled “administration fee”.
• Institutional custody (for example, SEI, Pershing, State Street): often 0.05% to 0.20%, with institutional-grade protections and consolidated reporting.

For HNW clients, the custody arrangement matters beyond the fee. Segregated custody at a globally systemically important bank provides a different level of asset protection from sub-custodied holdings on a retail platform. Clients increasingly ask about this, particularly when the total portfolio crosses into seven figures.

Layer 4: transaction costs

Often the least transparent layer. Transaction costs include bid/offer spreads, dealing commissions, stamp duty (0.5% on UK equity purchases), and foreign exchange spreads on overseas holdings.

Since MiFID II, DFMs are required to disclose transaction costs using the ex-ante methodology. In practice, these figures appear in annual cost illustrations but rarely feature in the original proposal. A turnover-heavy, direct-equity portfolio can carry 0.25% of transaction costs a year. A low-turnover, fund-based portfolio might be under 0.05%.

Ask providers to quote transaction costs on their typical portfolio before you compare DFMs. The FCA’s COBS handbook sets out the disclosure requirements, and providers should be able to supply these readily.

Illustrative total cost by service type

The progression is not linear. A passive MPS can deliver core market exposure for under 50 basis points all-in. A bespoke multi-asset portfolio with active management, institutional custody, and a tax-efficient structure might cost 1.65% or more, but offers substantially more personalisation, direct holdings, and non-fund exposures. Both can represent fair value for the right client. Neither represents fair value for the wrong one.

How to evaluate DFM charges in practice

The core question Consumer Duty asks is not “is this cheap?” but “is this fair value?” For fees, that means comparing on a total-cost basis, matched to the service delivered.

Ask for a personalised illustration

Published rate cards are a starting point, not an answer. Every DFM should be able to produce a personalised fee illustration for the actual portfolio size and mandate under consideration. Ask for:

• DFM management fee (tiered, if applicable, showing effective blended rate)
• Expected blended underlying fund OCF, with current holdings detail
• Custody or platform fee, tiered
• Estimated transaction costs (ex-ante, based on typical turnover)
• VAT treatment on each layer
• Any performance fees, exit fees, or specialist fund charges

If a provider cannot produce this within a week, that tells you something about how they operate. A firm that is vague about fees pre-engagement will not become clearer post-engagement.

Compare like with like

Compare DFMs serving similar client segments. A bespoke HNW DFM at 0.75% should not be benchmarked against a retail MPS at 0.20%, because they are delivering fundamentally different services. Our due diligence framework sets out the full evaluation process; on cost, the key is to build a like-for-like shortlist first, then compare.

Decompose the total

For each provider, break the total cost into its four layers and ask:

• Is each layer in line with the market for this type of service?
• Are any layers unexplained or bundled (a red flag)?
• Does the balance between DFM fee and OCF reflect the style claimed (for example, is a “low-cost index-heavy” portfolio actually carrying 0.60% OCF)?
• Does the custody arrangement match the client’s portfolio size and sophistication?

A well-structured proposal answers these questions without being asked.

Fee pressure and what’s driving it

The UK DFM market has been under sustained fee pressure for several years. Three forces are driving it:

• Passive competition. Low-cost multi-asset funds (Vanguard LifeStrategy, HSBC Global Strategy) have reset client expectations on what “balanced exposure” should cost. A DFM charging 1.20% all-in for a broadly similar blended portfolio will struggle to justify the premium under Consumer Duty.
• Consolidation and scale. The Investment Association has documented ongoing consolidation across the wealth sector. Larger DFMs use that scale to compete on MPS pricing, compressing the low end of the market.
• Regulatory transparency. Full ex-ante and ex-post cost disclosure under MiFID II has made fees more comparable than ever. Clients now receive detailed annual cost and charges reports that show the cumulative drag on returns.

The result: most DFMs have compressed MPS fees to 0.20% to 0.30% and shifted focus to bespoke and hybrid services where pricing can be sustained. For advisers, this means the MPS end of the market is becoming commoditised, while the bespoke end increasingly requires genuine personalisation and institutional infrastructure to justify the fee.

When higher fees represent fair value

Higher costs are not automatically poor value. For the right client, a fully bespoke service can deliver outcomes that no model portfolio matches. Fair value turns on whether the additional cost buys additional outcomes.

Legitimate reasons for higher DFM charges include:

• Genuine portfolio personalisation. Tax-managed positions, concentrated holdings incorporated carefully, specific ethical exclusions, or family-wealth restrictions that cannot be modelled at scale.
• Access to non-fund asset classes. Direct equities, individual bonds, alternatives, and private markets often require bespoke management and custody arrangements.
• Institutional-grade custody and reporting. Segregated accounts at a globally significant custodian, consolidated cross-entity reporting, and family-office-style service.
• Tax optimisation. Strategies such as CGT harvesting, loss utilisation, and structured withdrawals require individual portfolio management and are difficult to deliver in a model.

For HNW clients with complex needs, a turnkey multi-family office solution can deliver institutional capabilities at a total cost that is often no higher than a bespoke service with a smaller provider, once all layers are consolidated.

Conversely, higher fees do not represent fair value when:

• The DFM claims “bespoke” but delivers a lightly customised model portfolio
• Transaction costs are high because of unexplained turnover rather than mandate activity
• Underlying fund selection overweights expensive in-house products
• The custody charge does not reflect the protection being provided

This is the territory where adviser due diligence earns its keep.

Consumer Duty and fair value in practice

Under Consumer Duty, advisers must evidence fair value across the whole product chain, not just their own advice. That includes the DFM’s charges.

Practical steps to meet the obligation:

1. Document the cost comparison. File the personalised fee illustration from each DFM shortlisted, alongside the reasoning for the choice.
2. Review annually. Confirm that the costs still represent fair value given the actual service delivered and the client’s evolving needs. A DFM that was competitive in 2022 may no longer be.
3. Challenge drift. If transaction costs, fund OCFs, or platform charges creep up over time, raise it with the provider. Silence is not fair value.
4. Refresh on material change. New FCA guidance, mergers within the DFM’s group, or significant team changes all warrant a review.

The FCA’s PS22/9 policy statement sets out the fair value framework in full. In practice, the test is documentary: can you show, if asked, how you assessed the costs against the benefits, and why the outcome represents fair value for this specific client?

Negotiating on behalf of your client

For larger clients, fees are genuinely negotiable. Most DFMs have discretion on bespoke pricing, particularly at GBP 1m+ and above. Areas where negotiation is usually possible:

• Tiered breakpoints. Ask if the top tier can apply from a lower level.
• VAT treatment. Where advisory intermediation applies, some fees can be VAT-exempt.
• Platform fees. On larger portfolios, custody or platform fees are often the most flexible layer.
• Bundled pricing. A flat total expense ratio, rather than four separate layers, can be simpler for clients and often negotiable at HNW levels.

For adviser firms with scale, panel arrangements can secure preferential pricing across the book. This matters both commercially and for Consumer Duty: if you have negotiated better pricing for your clients, you can evidence that active effort.

Practical checklist for every DFM review

When evaluating or reviewing a DFM on charges, the working list:

1. Request a personalised fee illustration showing all four layers, net and gross of VAT
2. Compare against at least two alternative providers on a like-for-like basis
3. Reconcile the actual blended OCF with the stated investment style (passive, active, or hybrid)
4. Confirm the custody arrangement and fee structure against the client’s portfolio size
5. Review ex-ante transaction cost disclosure against historical turnover
6. Check for any performance fees, exit fees, or specialist charges
7. Confirm VAT treatment across each layer
8. Document the fair value assessment in the client file
9. Schedule an annual review of costs against outcomes
10. Re-run the comparison on material change of provider, client circumstances, or regulation

This discipline is the difference between a DFM selection that survives regulatory scrutiny and one that does not.

The adviser’s real job

Charges are not the only factor in DFM selection, but they are the only one that compounds year after year regardless of investment performance. Getting them right is one of the clearest ways advisers add measurable value.

The market has matured. Transparency is better than it was a decade ago. But the layers of cost still hide surprises, and the gap between headline fee and total client cost remains wide enough to matter. Advisers who decompose the total, compare like with like, and document the fair value assessment protect their clients and strengthen their own Consumer Duty position in the same motion.

For practices building long-term enterprise value, the discipline of rigorous fee analysis is also a differentiator. Clients notice. Regulators notice. And over a decade, the compounding difference shows up in returns.
