I'm not sure how much good it does but any scam emails can simply be forwarded to the National Cyber Security Centre,
https://www.ncsc.gov.uk/guidance/sus...-email-actions
Simply forward the email to
report@phishing.gov.uk
No forms to fill out, no complicated login/registrations, just forward to the above address.
You'll get a fairly immediate acknowledgement with some current statistics.
The sooner scams are reported the sooner the websites the scammers create to capture your details are shut down.
