I know nothing about the company but I do know about UK company law. A UK company is very easy to open, there's no oversight, you declare the truthfulness of your statements and that's it: it takes about 10 minutes, you could have a UK company by the end of today. The directors of the company in question are not British, so even in the worst case scenario where they break the law and are pursued, they can just skip the country and face no real recourse.

There are some opportunities that can be a meaningful demonstration of credibility, like registration with the FCA, but I don't see any evidence of that for this company. I would consider their incorporation (as a cic, not a for-profit company) meaningless in determining if they're credible.
