The most common cold-call pattern reported for UK geographic blocks like 01788 487 XXX is the 'utility supplier' scam — a caller claiming to represent your energy or broadband provider and asking you to confirm bank-account details to renew or 'protect' an existing tariff. Legitimate UK providers will never ask for full security details on an outbound call.
If a 01788 487 XXX 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.
