The UK investment fee is becoming a total, but not all of the rule is final

An investment can arrive with one neat percentage on its product page while the full cost sits in several places. The fund has a charge. A platform may levy another. Advice can add a fee. Cash waiting inside the account may earn interest, and the platform may keep some of it.

The UK Financial Conduct Authority now wants those pieces to read more like one cost story. Its July consultation proposes that platforms, advisers and wealth managers present their own charges alongside product costs and regularly account for the total cost of investing. It also covers fees charged on client cash and interest retained by firms.

That is the useful idea. The important qualification is that it is not all a finished rule.

Two regulatory tracks are moving at once. Final rules for Consumer Composite Investments, known as CCIs, are already in place and become fully effective on 8 June 2027. They will replace the more prescriptive PRIIPs and UCITS disclosure documents with product information designed around costs, risk and return, and past performance.

A separate consultation, CP26/24, would align and consolidate wider cost disclosures across investment distribution and advice with that CCI approach. Responses close on 21 August 2026. The FCA says it intends to publish final rules by the end of the year, so the detail may still change.

The distinction matters because “clearer investment disclosure” can otherwise sound like a single switch has already been thrown. Firms can use an optional transition route for CCI product summaries now, but the new product regime is not compulsory across the market until June 2027. The rules that would join platform, distribution and advice costs to that framework remain proposals.

The regulator’s evidence explains why the join matters. It says 30% of non-advised platform users surveyed did not know how much they were charged for investing. In a separate review of 132 current pre-sale product documents, only 6% met its plain-English readability test. Thirty-one per cent were rated difficult and 63% fairly difficult to read.

The FCA then tested those documents and 40 more for intelligibility. All 172 fell below the assessment benchmark, which the review described as GCSE level. Complex words, industry jargon and technical phrases were the main problems.

This is not only a complaint about long sentences. A readable product charge can still be incomplete if the reader has to find a platform fee in one place, an advice cost in another and the treatment of cash somewhere else. The proposed framework is meant to make the distribution chain visible as a whole.

Under the consultation, distributors would show their own costs alongside the product costs prepared in the CCI format. They would also give regular information about the total cost of investing. The scope reaches MiFID investment business, insurance distribution and other designated investment business, rather than one narrow type of app or fund.

That does not necessarily mean every firm will produce an identical receipt. The FCA’s direction is deliberately less prescriptive about presentation. Manufacturers will have freedom to design product summaries, while distributors can build journeys that highlight required information. Common calculation standards remain for costs, risk and return, and past performance, but firms have room to explain them differently.

Flexibility creates its own test. A more attractive card is not automatically a more complete explanation. A short headline figure can help comparison only if it clearly identifies what is included, what sits outside it and the period it covers. The regulator’s Consumer Duty still requires communications that support understanding, not merely a cleaner screen.

Cash is a revealing part of the proposal. Investment accounts often hold uninvested money before a purchase, after a sale or while income accumulates. A platform may receive interest on that pooled cash and pass on all, some or none of it. It may also charge a fee connected with holding cash.

The FCA raised concerns in 2023 that some platforms and SIPP operators retained interest in a way that might not represent fair value, while some also charged customers for the cash they held. It called that combination “double dipping” and told firms to stop it. The new consultation would bring disclosures about cash fees and retained interest into the wider cost framework. It does not create a new guarantee that every cash balance will earn the Bank of England base rate or any particular return.

Nor does clearer disclosure decide whether an investment is suitable, cheap or likely to perform well. A lower fee does not remove market risk. A higher fee is not proof of better service. Costs reduce what an investor keeps, but the relevant comparison depends on the product, service, risk and time horizon. The disclosure is evidence for a decision, not the decision itself.

For now, the practical reading task is to separate today’s documents from tomorrow’s rules. A product may already offer a CCI-style summary during the transition. Current platform and advice disclosures still apply. The proposed consolidated presentation has not yet been finalised, and the August consultation may alter it before the FCA publishes a policy statement.

The reform’s real promise is modest but valuable: one clearer view of the layers between a product’s quoted charge and the amount an account actually costs to use. Its success will not be measured by whether the industry produces shorter documents alone. It will be whether a person can find the whole cost, understand the boundaries of the number and compare like with like without becoming a regulatory archaeologist.
