Megan Thomas, Which? investments writer, says:
Barclays Smart Investor scored the full five stars for its ease of use, and you can integrate Barclays Smart Investor more easily into the rest of your finances if you use its banking services.
Barclays tended to run close to the average on fees, so while you could do worse, you could also do better. You should be wary of the potentially high foreign exchange fees at Barclays, as you'll pay 1% on any international trade worth less than £5,000.
You can invest in a broad range of assets with Barclays, but other providers offer more options.
Barclays customers gave it a 72%, the ninth-highest score of any platform in our survey.
