This block — 01737 80 XXXX — was allocated by Ofcom to TGL Services (UK) Ltd in 2015. TGL Services (UK) Ltd either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single 01737 80 XXXX prefix can be used by many different organisations. You can verify any allocation against Ofcom's National Telephone Numbering Plan, which is updated weekly.
Some calls from blocks like 01737 80 XXXX are actually one-ring 'wangiri' calls — the line rings once and disconnects, hoping you'll call back. While wangiri is more common from foreign numbers, UK number-spoofing means 01737 80 XXXX-style ringbacks are not unheard of. Don't return missed calls from unknown numbers without checking them first.
If a 01737 80 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.
