For many households in the UK, landline spam calls are more than just a nuisance—they can be dangerous. Scammers often target elderly people through impersonation and caller ID spoofing. While registering with the Telephone Preference Service (TPS) helps reduce legal telemarketing, it doesn’t stop fraudsters.
This is where landline call blocking devices come in. But with so many options available, what features really matter? This blog explores the essential functions a call blocker should have to keep you and your loved ones safe.
Why Do You Need a Landline Call Blocking Device in the UK?
Despite protections like TPS, nuisance calls remain a serious problem:
-
Scammers ignore the law: Fraudsters and overseas call centres don’t follow TPS.
-
Caller ID spoofing is rising: Criminals disguise their numbers to look official.
-
Elderly people are vulnerable: They’re often at home during the day and more likely to answer unknown calls.
-
Financial loss risk: According to UK Finance, UK victims lost over £1.2 billion to scams in 2024, many through phone calls.
A call blocking device helps by filtering, screening, and blocking unwanted numbers before they can cause harm.
Summary: UK households need call blockers because TPS alone can’t stop overseas fraudsters, spoofing scams, and persistent nuisance callers.
What Features Should a Call Blocking Device Have in the UK?
When choosing a device, look for these key features:
-
Large blocked-number capacity – The ability to store 2,000+ blocked numbers ensures long-term protection.
-
Pre-programmed scam numbers – The best devices come preloaded with thousands of known nuisance and scam numbers.
-
One-touch blocking button – Lets you block unwanted calls instantly during or after the call.
-
Caller ID compatibility – Essential for identifying and screening calls before answering.
-
International and withheld number blocking – Prevents scams that often originate overseas.

Whitelist function – Allows only trusted numbers (like family, friends, and doctors) to get through.
-
Display screen with call log – Helps track recent calls and identify repeat offenders.
-
Ease of use for elderly users – Large buttons, clear screens, and simple instructions make it senior-friendly.
Devices like CPR Call Blocker include most of these features, which is why they are widely recommended in the UK.
Summary: An effective UK call blocker should have large capacity, preloaded scam lists, one-touch blocking, caller ID, whitelist options, and user-friendly design.
How Can a Call Blocking Device Protect You From Scams?
Call blockers reduce exposure by:
-
Filtering unknown calls before they ring through.
-
Blocking spoofed numbers often used by HMRC or bank scammers.
-
Preventing repeat offenders from calling back after being blocked once.
-
Reducing stress for elderly relatives who may feel pressured by scam calls.
Summary: Call blockers protect households by filtering unknown numbers, blocking repeat scammers, and reducing stress for vulnerable family members.
