Across the UK, fraudsters are using increasingly sophisticated tactics to target vulnerable households — particularly those with older adults or people living alone. These scams often start with a simple phone call. A landline call blocker offers an easy, reliable way to stop these calls before they cause harm. Let’s explore how they protect families and prevent fraud.

Why Are Vulnerable Households Targeted by Scammers?
Criminals target vulnerable people because they are more likely to trust a friendly voice or respond to authority figures. Many scams involve callers pretending to be from banks, utilities, or government departments.
Common reasons include:
- Trusting nature: Many older people believe phone calls are more genuine than online messages.
- Lack of scam awareness: They may not recognise common fraud tactics like spoofed numbers or fake “urgent” requests.
- Isolation: Scammers take advantage of loneliness by engaging in friendly conversation before asking for money.
- Predictable routines: Criminals know when older adults are likely to be home and available.
Summary: Fraudsters target vulnerable people because they’re more trusting, isolated, and less aware of modern scam tactics.
How Do Landline Call Blockers Help Prevent Fraud?
Landline call blockers use technology to intercept suspicious or unwanted calls before they reach your phone. By automatically rejecting scam numbers and allowing only trusted ones, they create a strong barrier against fraud.
Here’s how they protect UK households:

Summary: Call blockers automatically filter scam calls and ensure vulnerable households only receive safe, trusted communication.
How Can Families Use Call Blockers to Keep Loved Ones Safe?
Families play a crucial role in maximising the benefits of a landline call blocker. When used together with awareness and support, these devices can dramatically cut fraud risks.
Here’s how families can help:
- Set up whitelist mode: Add trusted contacts like family, doctors, and carers.
- Teach simple use: Show older relatives how to press the block button confidently.
- Monitor activity: Review blocked numbers occasionally to ensure no important calls are missed.
- Stay updated: Keep the call blocker’s database current to block new scam numbers.
