Inspired by Conor's recent post and as someone who's used their fair share of different investing platforms, I wanted to summarise some of the S&S ISA options currently available to U.K. investors, particularly as the comparison sites out there are either nowhere near comprehensive enough or just plain out of date.

Given the impact of fees on investment returns over time, it's not an area that is wise to overlook for long-term investors.

The table below shows ISA options for investors that are interested in buying shares in specific businesses rather than 'robo-advisors'. If the brokerage offers tiered products, I'm using the bottom-tiered (basic) pricing structure. Any percentages shown in the share fee columns are a % of the total trade price.

While Trading 212 might seem the best offer out there currently, it should be taken into account that their business model is at least somewhat reliant on the success of their CFD product. Their FX charge also increased in the recent past. If I were choosing an ISA based on ease of use, Freetrade would win out - to me, they seem to have managed to foster brand trust since launching in a way that T212 hasn't.

In terms of the more established players, Interactive Brokers are currently the stand-out provider (and my personal choice), with the lowest fees on the market. As their ISA product was only launched this year, it remains to be seen how the other brokerages will react.

Hopefully the level of competition will result in lower fees and more transparency over time!
