MiFID II introduced comprehensive cost and charges disclosure for UK financial advisers. Although the UK has diverged from EU MiFID II rules post-Brexit via the FCA’s own regime, the core principle — that clients must understand exactly what they are paying in pounds as well as percentages — remains central. Under Consumer Duty, these requirements have become even more outcome-focused.

What Must Be Disclosed?

Under COBS 6 and related FCA rules, advisers must disclose:

  • All adviser charges — initial, ongoing, and any ad hoc charges
  • Product costs — platform charges, fund OCFs, DFM fees
  • Aggregated costs — total cost in both percentage and monetary terms
  • Effect of costs on return — how cumulative costs impact projected value over time

Ex-Ante vs Ex-Post Disclosure

Ex-ante (before) must be provided before any transaction is agreed. It should be personalised — a client investing £200,000 should see that total costs of 1.8% amount to £3,600 in year one, not just a percentage.

Ex-post (after, annually) requires a statement of all costs charged during the year alongside portfolio performance. Under Consumer Duty, this should clearly evidence value delivered relative to fees charged.

Typical All-In Cost Ranges

Cost ComponentTypical Range
Adviser ongoing charge0.50–1.00%
Platform charge0.15–0.45%
Fund OCF0.10–0.75%
DFM charge (where applicable)0.20–0.50%
Total all-in0.95–2.70%

Consumer Duty: Fair Value Overlay

Since July 2023, Consumer Duty adds a fair value requirement on top of cost disclosure. Advisers must demonstrate that the service represents fair value — not just disclose costs accurately. Annual review processes should document value delivered, not just fees charged. Clients paying ongoing fees without receiving annual reviews are a significant regulatory risk area.

Post-Brexit UK Divergence

The FCA has been reforming the MiFID II framework — removing the rigid 10% depreciation notification requirement and streamlining certain disclosure formats. The underlying obligation for transparent cost disclosure remains unchanged and has been reinforced under Consumer Duty.
