Negotiating Private Banking Fees: What You Should Pay and How to Reduce It

Private banking is expensive, and for good reason — the level of service, access, and capability offered by the best private banks is genuinely valuable. But "expensive" does not mean "unable to be negotiated," and the opacity of fee structures at many institutions often means that clients pay significantly more than they need to, for less service than they are entitled to expect.

This guide explains how private banking fees work, what you should and should not accept, and how to approach fee negotiation effectively.

The Three Layers of Private Banking Charges

Before discussing specific rates, it is essential to understand that private banking typically involves three distinct layers of charges — and that the headline rate presented at account opening often reflects only the first.

Layer 1 — Adviser or management fee: The charge for the private banking relationship itself. This is the fee quoted in initial conversations and stated in the initial agreement. It is either AUM-based (charged as a percentage of assets), a flat annual fee, or transaction-based.

Layer 2 — Investment management or custody fee: If your assets are held in a discretionary or advisory portfolio, there is typically an additional fee for the investment management service and the custody of your assets. This may be absorbed into the Layer 1 fee (a bundled mandate) or charged separately.

Layer 3 — Underlying fund and product charges: If your portfolio includes investment funds, ETFs, or structured products, each of those instruments carries its own annual charge (the OCF or TER). These are typically not disclosed as a separate line item but are deducted from the fund value daily. They can add 0.5–1.5% per year to the effective total cost.

When a private bank quotes you a management fee of "0.75% per year," they may mean Layer 1 only. The full effective annual charge, including all three layers, may be 1.5–2.5%. This is the figure that matters for assessing value.

Common Fee Structures

AUM-Based Fees

The most common private banking fee structure charges a percentage of assets under management. Typical ranges:

• £1–5 million AUM: 1.0–1.5% per annum
• £5–10 million AUM: 0.75–1.0% per annum
• £10–50 million AUM: 0.5–0.75% per annum
• £50 million+ AUM: 0.25–0.5% per annum (often negotiated individually)

These are gross ranges. Some private banks apply a tiered structure automatically — lower rates apply to balances above a threshold. Others require explicit negotiation for any rate reduction.

AUM fees are charged regardless of portfolio performance. A 1% AUM fee on a £5 million portfolio costs £50,000 per year whether the portfolio rises 10% or falls 5%. Some providers offer performance-linked fee structures (typically a lower base fee plus a share of outperformance above a benchmark), but these are less common in traditional private banking than in alternative investment management.

Flat Annual Fees

Some private banks offer a flat annual fee for the banking relationship, covering a defined scope of services. This is more common at the lower end of the wealth spectrum (£500,000–2 million) and for clients who primarily use banking services rather than investment management.

Flat fees range from approximately £5,000 to £25,000 per year, depending on the institution and the services included. For clients with very large portfolios where an AUM fee would be disproportionate to the cost of providing the service, a flat fee arrangement can represent very good value — and is worth requesting explicitly.

Transaction-Based Fees

For portfolios managed on an advisory rather than discretionary basis, some private banks charge per transaction — per trade, per currency conversion, per wire transfer. This model was more common historically and has largely been replaced by AUM or flat fees for investment portfolios, but it persists in some legacy relationships and for specific transaction types.

Watch for hidden transaction charges even in AUM-based mandates: some banks charge separately for FX conversions (at a marked-up rate rather than a fee), CHAPS transfers (£25–40 each), international wire transfers (£30–50 each), and certain custody transactions.

Hybrid Structures

Many private banks use a hybrid: a lower AUM fee (0.5–0.8%) for the relationship, plus specific transaction charges for certain services. The critical question is which services are included in the AUM fee and which are charged additionally.

MiFID II Disclosure Requirements

The Markets in Financial Instruments Directive II (MiFID II) introduced requirements for investment firms to disclose the full costs and charges of their services to clients, on both an ex-ante (upfront estimate) and ex-post (annual actual) basis. This applies to all FCA-authorised investment firms, including private banks.

MiFID II requires the disclosure to cover:

• All charges associated with the portfolio management service
• All transaction costs
• All third-party charges (fund charges, custody fees)
• An aggregated total charge figure, expressed both as a percentage and in monetary terms

In practice, many private banks provide MiFID II disclosures that are technically compliant but difficult to compare. The ex-post annual statement (which shows what you actually paid in the previous year) is the most useful document for assessing total cost.

Ask for a copy of your MiFID II costs and charges statement if you have not received one. You are legally entitled to it. If the total figure surprises you, use it as the basis for a fee discussion.

FX Margins: The Hidden Cost

One of the most significant hidden charges in private banking is the FX margin applied to currency conversions. Rather than charging an explicit fee for currency exchange, many banks apply a spread between the interbank rate and the rate offered to clients — typically 0.5–1.5% for spot transactions and up to 2–3% for smaller transactions.

For clients who regularly receive income, make investments, or spend in multiple currencies, FX margins can represent a significant annual cost that never appears as a line item on a fee statement.

Request from your private bank the interbank rate versus the rate they apply to your transactions for any given currency pair. Compare this with a specialist FX broker such as Moneycorp or Global Reach. If the margin is materially higher than available alternatives, negotiate — or route currency transactions through a specialist provider for large conversions.

When and How to Negotiate

At Relationship Initiation

The best time to negotiate fees is before assets are transferred. Once you are a client, the bank's leverage increases — moving assets is expensive and time-consuming. Before opening an account, obtain a written fee schedule and negotiate on the following:

• AUM fee rate for each tier of assets
• FX margin or flat-rate FX pricing
• Transaction charges (CHAPS, international wires, custody)
• Any annual minimum charge

Do not accept verbal assurances — get all agreed terms in writing as part of the client agreement.

At Relationship Reviews

Annual or biennial relationship reviews are a natural opportunity to revisit fees. Relevant grounds for requesting a reduction:

• Significant growth in assets (moving into a higher tier)
• Portfolio underperformance relative to benchmark
• Competitive offers obtained from alternative providers
• Reduction in services used
• Introduction of new family members to the bank

Using Competitive Pressure

The most effective negotiating tool is a credible alternative. If you have received a firm written proposal from another private bank at a materially lower rate, presenting this to your existing banker gives them a clear decision: match the rate or lose the relationship.

This works best where the relationship is genuinely portable — you have not committed assets to illiquid structures that are difficult to transfer. Before initiating a competitive process, ensure you understand the full cost and process of moving assets (particularly investments in custody, which may require in-specie transfer or liquidation).

Requesting an Unbundled Mandate

Where a bank provides bundled banking, investment management, and custody under a single headline fee, request an unbundled analysis — what does each component cost separately? You may find that you can achieve better value by maintaining the banking relationship under one fee structure and using a lower-cost platform or DFM for the investment management.

The RFP Process for Switching Private Banks

For clients seriously considering changing their primary private banking relationship, a formal Request for Proposal (RFP) process produces better outcomes than informal conversations. An RFP sent simultaneously to three to five banks creates competitive dynamics that rarely arise in bilateral discussions.

A well-structured RFP includes: your current asset profile and banking requirements, a request for both AUM fee schedules and all-in total charge estimates, service scope expectations, and a clear decision timeline. The responses allow direct, structured comparison of both price and capability.
