One way is to select a low-cost SIPP. Some SIPPs have lower fees and charges than others. Another way is to invest in investments that have low fees. ETFs, for example, generally have much lower fees than actively managed funds. It’s worth noting that on some platforms, some investments attract lower custody fees than others. For example, on platforms such as Hargreaves Lansdown and AJ Bell Youinvest, the annual custody fees for accounts with shares are lower than those for accounts with funds. A third strategy that can help keep fees low is to minimise trading. Fees from excessive trading can quickly add up.
