We recommend either Simply Ethical or Wahed Invest (https://campaign.wahedinvest.com/ifg). If you set up with Wahed and then call them, they are live with their SIPP but just not public about it. We also really like Pensionbee‘s offering that is sharia-compliant and cost-effective for smaller pensions (under £50k).
You can also DIY it with someone like AJ Bell and then just use that SIPP account to buy some Islamic funds.
Do subscribe to our mailing list and we’ll share with you a detailed SIPP article in the coming weeks and months.
