Energy-rebate and 'green grant' scams have been linked to UK landline blocks like 01529 55 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 01529 55 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.
