How to Stop Scam Calls on Your Elderly Parent’s Landline (UK Guide 2026)

Do you want to stop scam calls on your elderly parent’s landline? If so, you are not alone. If your mum or dad still uses a home phone, it probably rings all week. First, a fake bank team calls. Then a bogus broadband warning plays down the line. Next, a spoofed HMRC threat arrives. And of course the pushy sales lines never stop. So why the landline? Because that is where older people are easiest to reach. In fact, research from the University of Portsmouth makes the point. For people aged 75 and over, the landline was the top route for scammers. Indeed, up to 40% of older adults face fraud attempts every day, week or month.

But the good news is simple. You can act today. Better still, your parent does not need to learn anything new. Instead, they keep their familiar handset. So this guide walks through every option. First, it covers free steps that take ten minutes. Then it moves to a service that blocks scam numbers for you. Finally, you choose what fits your family.

Why older adults get more scam calls

Scammers pick older people on purpose. For a start, landline numbers are easy to find. In fact, many still sit in old directories. Older adults also tend to answer every call. They do it out of politeness, or in case it matters. Meanwhile, criminals know all this. For example, they know this generation is more likely to have savings. They also know a caller who claims to be from the bank sounds convincing. And they know many older people stay home during the day.

Still, the damage runs deeper than money. Independent Age found that older victims lose £4,000 on average. Yet the emotional toll is often worse. In fact, nearly a third of over-65s say fraud has harmed their mental health. As a result, many live on edge. They flinch every time the phone rings. So protecting the landline protects their peace of mind too.

The types of scam calls targeting UK home phones in 2026

A few scams dominate UK landlines right now. First, there is the fake bank scam, the classic. A caller says your parent’s money is at risk. Then they push them to move it to a “safe account”. Meanwhile, recorded robocalls are everywhere too. Typically, they warn about broadband, Amazon Prime or an unpaid bill. Worse still, number spoofing hides the source. Because the display shows a local or official number, the call looks real. Finally, there is the cruel TPS renewal scam. Here, fraudsters claim the free register has expired. Then they demand a £35 to £40 fee. Clearly, spotting each trick is hard. So blocking the calls first is far easier.

Option 1: Free steps you can take right now

First, start with the basics, because they cost nothing. Register your parent’s number with the Telephone Preference Service (TPS). It is free at tpsonline.org.uk. Better yet, registration never expires. It also forces UK companies to stop marketing calls to that number. So do it on day one. For more background, the ICO explains your rights in its nuisance calls guidance.

Next, report the worst offenders. The Information Commissioner’s Office collects reports of nuisance marketing calls. Then it uses them to fine the firms responsible. Instead, report genuine scams to Action Fraud. That is the UK’s national fraud reporting centre. Also check your parent’s phone package. In many cases, providers now let you bar withheld or international numbers for free. These free steps help. On their own, though, they will not stop scam calls.

Why TPS alone is not enough

To be honest, the TPS website admits its limits. Registration only binds legitimate UK businesses. So overseas call centres ignore it. Likewise, outright criminals ignore it too. And those are exactly the people who run the dangerous scams. True, TPS cuts down legal marketing calls. However, it does nothing to stop scam calls from spoofed numbers abroad. So treat the free steps as a floor, not a fix. To really protect your parent, then, you need to filter calls as they arrive.

Option 2: A VoIP service to stop scam calls automatically

The most complete fix in 2026 looks different. Instead, you move your parent’s landline to a modern digital (VoIP) service. This time, scam blocking comes built in. So you do not bolt a box onto an old line. For example, Phonely’s CallGuard works this way. It checks every incoming call against a central database of known scam and nuisance numbers. Crucially, that check happens before the phone even rings.

How CallGuard works to stop scam calls: hourly updates and police backing

Here is the key difference. Basically, the protection updates itself. For instance, CallGuard refreshes its block lists as often as every hour. So when a new scam campaign hits UK numbers, the system shuts it down for your parent. Meanwhile, no one in the family lifts a finger. Better still, the block lists draw on shared scam-number intelligence. In fact, police and Trading Standards endorse it. As a result, CallGuard stops known bad callers on the spot. Yet trusted family and friends still ring through. Because the filtering runs in the network, not on a box, it keeps pace as scams evolve.

How to set it up for a parent remotely in under 10 minutes

Happily, you do not need to be in the same house. Nor do you need the same city. In practice, an adult child can set the whole thing up for a parent. And that suits most families perfectly. To help, Phonely’s guide to buying for someone else walks you through it. First, you choose the plan. Then you keep the existing number. After that, you manage the trusted-contacts list from your own phone. Meanwhile, your parent just answers their familiar handset. Typically, the setup takes under ten minutes. From then on, you add or remove approved callers whenever you like.

What UK police and Trading Standards say

Police forces and Trading Standards teams have warned about this for years. In short, call blocking is one of the best ways to protect older residents. Many therefore hand out or recommend blocking technology to people they have helped. Their advice comes down to three steps. First, register with the TPS. Second, never give bank or card details to an incoming caller. Third, put a blocker in place to stop scam calls before your parent has to judge them under pressure. Charities agree. For example, Age UK publishes regular scam-awareness resources. Above all, it stresses one thing. No one should feel embarrassed. After all, the criminals are professional and relentless.

Frequently asked questions

Can I keep Mum’s existing number?

Yes. Basically, a digital service like Phonely keeps the existing landline number. So friends and family do not need to learn a new one. And nothing changes in how your parent uses the phone. In short, the number simply moves across during setup.

Does it work with her existing phone?

In most cases, yes. Your parent keeps the handset they know, with the use of an adapter. So there is nothing new to learn. Meanwhile, the scam blocking runs quietly in the background. As a result, the phone just rings less, and only for callers who should get through.

Our recommendation

So start today with the free steps. First, register the number with the TPS. Then report persistent callers to the ICO and Action Fraud. After all, these cost nothing and always help. Still, stay realistic. TPS will not stop the scammers who pose the real danger. Because they work from overseas, they simply ignore it.

For the most complete, hands-off protection, though, go further. In that case, a VoIP service with built-in blocking is the strongest choice. This matters even more as the UK switches to digital landlines. Above all, CallGuard is built to stop scam calls automatically. First, it blocks more of them. Second, it updates itself against new threats. Third, it lets you manage everything from afar. So your parent keeps their number, their handset and their peace of mind. In short, Phonely’s CallGuard is made for exactly this. And you can set it up for a parent in under ten minutes.
