The HMRC-impersonation scam continues to be the most-reported telephone scam in the UK, and blocks like 01704 41 XXXX are sometimes spoofed for these calls. HMRC will never threaten arrest, demand payment by gift card or cryptocurrency, or use a 'press 1 to speak to an officer' menu. If in doubt, hang up and contact HMRC on the number printed on their gov.uk page.
If a 01704 41 XXXX number called you and you're not sure who it was, the safest steps are: don't return the call until you've verified it (search the full number online first), don't share personal or financial details, and register the number with the Telephone Preference Service (TPS) if it's a marketing call. Persistent unwanted calls can be reported to Ofcom and the ICO. To block a specific number on most UK mobiles and landlines, you can also enable network-level call screening through your provider.
