If you have money invested in funds with relatively high annual management funds, you should investigate clean funds.
Following the introduction of the Retail Distribution Review (or RDR) by the Financial Conduct Authority (FCA) in 2013, most fund managers have introduced ‘clean’ share classes of their funds. Clean funds are so called because the AMC no longer includes any platform fee or trail commission. With clean funds you will pay a lower AMC, typically 0.75%, and an explicit platform charge.
This might mean a fund previously charging a total AMC of 1.5% may be switched into a clean one paying 0.95%. (0.75% + platform charge of 0.2%) This would make an enormous difference over a no. of years.
