This block — 0800 915 XXXX — was allocated by Ofcom to GCI Network Solutions Limited in 2023. GCI Network Solutions Limited either operates the numbers directly or sub-allocates them to resellers and downstream carriers, which is why a single 0800 915 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.
Insurance and accident-claims cold calls remain a heavy source of unsolicited 0800 915 XXXX-prefix traffic. Since 2019 it has been illegal under UK law to make unsolicited cold calls about pensions, and similar tightening is in force for insurance leads. You can register your number with the TPS for free to block legitimate UK marketing calls.
If a 0800 915 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.
