Spam phone calls continue to be a significant issue for mobile and landline users in the UK. These unwanted calls can cause a lot of frustration, disrupt daily life, and in some cases, be a form of fraud or scam. As technology advances, so do the tactics used by scammers and telemarketers. Whether it’s a persistent robocall or a disguised number aimed at gaining your personal information, spam calls can be alarming and difficult to avoid. This article highlights some of the most reported spam phone numbers in the UK in 2025, including detailed information about each one.
Introduction to Spam Calls in the UK
Spam calls are unsolicited and often unwanted phone calls made by businesses, scammers, or telemarketers. These calls can be categorized into two main types:
- Telemarketing Calls: These calls are typically made by legitimate companies promoting products or services. However, they can still be bothersome, especially if they occur frequently or at inconvenient times.
- Fraudulent Calls: These are calls made by scammers who try to steal your personal information, bank details, or money. They often pretend to be government officials, banks, or even well-known companies.
The rise of robocalls (automated recorded messages) and the increase in fraudulent activity has made it difficult for consumers to discern between legitimate calls and potential scams. The following is a list of phone numbers frequently reported as spam in the UK, along with details about each one.
