I would double-check every Hestia Invest domain

The part that would concern me here is that the FCA warning lists several websites for Hestiainvest / Hestia Invest, including hestiainvest.com. It says the firm is not authorised by the FCA and may be targeting people in the UK.

I would not assume that a different-looking URL is safe just because it uses the same brand. I would compare the exact address and firm details with the warning, and keep in mind that the notice is about UK authorisation rather than an account-specific complaint.
