Energy-rebate and 'green grant' scams have been linked to UK landline blocks like 0114 704 XXXX. The caller claims you're eligible for a government rebate or smart-meter grant and pressures you into giving bank details to receive it. Real government rebates apply to your bill automatically — no outbound call is needed.
If a 0114 704 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.
