Everything you need to know about investment fees uk in the UK.
Investment fees may seem small in percentage terms, but they have an enormous impact on your returns over time due to the effect of compounding. A difference of just 1% per year in total fees can reduce your final portfolio value by 20–25% over a 25-year investment period.
For example, investing £200 per month for 30 years at 7% annual growth would give you approximately £243,000 before fees. With total annual fees of 0.5%, your pot would be around £220,000. With fees of 1.5%, it would be approximately £183,000 — a difference of £37,000 caused entirely by higher fees.
Understanding and minimising fees is one of the most reliable ways to improve your long-term investment returns. Unlike market performance, fees are within your control.
An investment platform (also called a broker or fund supermarket) is where you hold your investments. Platform fees are charged for the administration of your account and access to their services. Common charging structures include:
For a £50,000 ISA portfolio, the difference between a platform charging 0.45% and one charging 0.15% is £150 per year. Over 20 years with growth, this difference compounds significantly.
Every investment fund charges an Ongoing Charges Figure (OCF), sometimes called the Total Expense Ratio (TER). This covers the fund manager's fee and the fund's operating costs. Typical charges:
Research consistently shows that the majority of actively managed funds fail to outperform their benchmark index after fees over the long term. This is a key reason why low-cost index tracker funds have become increasingly popular.
💡 When comparing fund charges, always look at the OCF rather than just the Annual Management Charge (AMC). The OCF includes additional costs like custodian fees, audit fees, and regulatory charges that the AMC does not. The OCF gives a more complete picture of what you are paying.
Beyond the headline platform and fund fees, several other costs can erode your returns:
Your total annual investment cost is the sum of all fees: platform fee + fund OCF + any adviser charges + transaction costs. For a typical DIY investor using a low-cost platform and index funds, total costs might be 0.20–0.50% per year. For an advised investor using active funds, total costs could be 1.50–2.50% per year.
The difference between these two scenarios over 25 years on a £100,000 portfolio is potentially £50,000–£80,000 in extra fees and lost growth — a staggering amount that justifies careful attention to costs.
⚠️ Be wary of investment products with entry charges, bid-offer spreads, or performance fees on top of the standard OCF. These additional layers of cost make it extremely difficult for the investment to deliver competitive returns after all fees are accounted for.
