Castletrust.co.uk (Domain) Investigation Report
Generated on Jun 9, 2026
Β Why we think so?Β
π¦ castletrust.co.uk appears to be the legitimate Castle Trust Bank site, not a scam domain. The site has a long registration history, a valid SSL certificate, UK-based traffic, public contact details, a physical London address, and a Google Business Profile with 4.5β from 268 reviews. Its infrastructure also looks normal for a regulated financial firm, using Amazon Route 53, Cloudflare, Mimecast, Google Workspace, Salesforce, and other common enterprise services.
One important caution: there is an FCA warning about a different lookalike domain β castletrustb.com β which is a clone of an authorised firm. That warning does not point to castletrust.co.uk itself, but it does mean users should verify the exact domain and email address before sharing any financial information.
Overall, this looks authentic and low risk, with the main threat coming from impersonation attempts rather than the domain itself. β
