Best Home Phone Service UK 2026: VoIP, Scam Blocking and BT Alternatives Compared

Choosing a VoIP home phone in 2026 is harder than it used to be. Providers now sell everything from full broadband bundles to a small adapter that plugs into your router. Scam calls target home phones in record numbers. And the copper network that carried landline calls for decades is closing for good.

This guide compares the main UK options on price, scam protection, number porting and contract terms. Use it to pick the VoIP home phone that fits your household.

Why home phone services are changing in 2026

The PSTN switch-off drives most of this change. PSTN stands for the Public Switched Telephone Network, the copper system behind traditional landlines. It closes for good on 31 January 2027. Regulators pushed the date back once from December 2025, but Openreach now says it is final and will not move again.

This is not a distant problem. Openreach has already run a stop-sell across most of the country, so you can no longer order or change a copper line. Migration is moving fast too. Ofcom counted 5.2 million PSTN landline customers in July 2024 and just 3.2 million a year later. More than a million UK households have dropped their landline altogether.

What replaces the copper line is a home phone that runs over your broadband. People call it VoIP, digital voice or a digital landline. They all mean the same thing. Your voice travels as data over the internet, and you still pick up the handset and dial as normal. The difference is that a VoIP home phone costs less to run and supports modern features like real-time scam blocking.

Switching now puts you in control. You choose the provider and plan rather than waiting for your supplier to move you automatically. It is also easier than ever. Since One Touch Switch launched, more than 1.6 million people have changed landline or broadband provider, and over 300 providers have signed up. You can read Ofcom’s consumer switching data for the full picture.

What to look for in a VoIP home phone service

These services vary more than you might expect. The cheapest plan can prove poor value if it drops the features you need. Check these four things before you commit.

Call quality and reliability

A good service sounds as clear as the old copper line, or clearer. Any standard UK broadband carries enough bandwidth for reliable calls, so you do not need a fast connection. The one real trade-off is power and internet outages, when a broadband phone stops working. Look for a provider that sends offline alerts, and keep a charged mobile for emergencies.

Scam and nuisance call protection

Scam calls to home phones cost UK victims hundreds of millions of pounds each year, and they hit older people hardest. A modern VoIP home phone earns its keep here. Because calls arrive as data, a provider can screen and block suspicious numbers in real time. The old copper network never could. Protection varies a lot between providers, so treat it as a headline feature.

Number porting

Most households want to keep the number they have used for years. Nearly all reputable providers can port your existing landline number across, though timescales differ. With most services the move takes around five to seven working days, and the provider handles it for you. Check that porting is free rather than an extra charge.

The main VoIP home phone options compared

The table below compares five common ways to keep a home phone in 2026. Four are VoIP home phone services. The fifth, trueCall, is a call-blocking device that sits on top of an existing line rather than a service in its own right. Prices are current at the time of writing and include VAT where the provider states it.

A few things stand out. Voipfone wins on monthly price but gives you only 100 minutes and basic call blocking. BT and TalkTalk keep everything on one bill, yet both tie your phone to their broadband and a 12-24 month contract, and BT costs the most here. Phonely sits mid-table on price and leads on built-in protection, which is why it tends to win when scam blocking matters.

Which VoIP home phone is best for scam protection?

If fraud and nuisance calls worry you most, let the blocking system drive your choice. Here the newer VoIP-first providers pull ahead of the traditional networks.

BT’s Enhanced Call Protect comes free for its customers and has stopped millions of scam and spam calls. It mostly works after the event, though, by sending suspected scams to a junk voicemail once they reach your line. Phonely’s CallGuard acts earlier. It blocks known scam numbers before your phone rings, and suspicious callers hear a warning that Phonely monitors the call, so most fraudsters hang up.

How CallGuard compares

Police forces across the UK endorse it, the BBC’s Scam Safe campaign featured it, and it won the Digital Inclusion Award at the 2026 AbilityNet Tech4Good Awards. You can see how it works on the CallGuard page.

Which VoIP home phone is best for elderly parents?

Setting up a phone for an older relative is a different job. You want simplicity, reliability, strong scam protection, and a way for family to help without taking over.

Phonely suits this situation. The existing handset keeps working through a free adapter that plugs into the router, so there is nothing new to learn. You can port the number across, so nothing on the fridge magnet changes. Family members can watch over calls, offline alerts warn trusted contacts if the connection drops, and CallGuard quietly blocks the scams that target older people. The service also stands alone, so you do not have to switch broadband at the same time. If the number is the sticking point, the transfer your number page explains the steps.

Frequently asked questions

Can I keep my existing phone number?

In almost all cases, yes. Every major VoIP provider can port your existing landline number across. With Phonely the move takes about five to seven working days, and we handle it for you. Prefer a fresh start? You can choose a new number instead. Porting only gets tricky if you have already closed the old account, though some providers can still recover the number.

Do I need a new phone?

No. Your existing home phone works with a small VoIP adapter that sits between the handset and your router. Phonely includes the adapter free with every plan with annual payment, so you buy and learn nothing new. You can add a dedicated handset during signup if you prefer, but it stays optional.

What happens if the broadband goes down?

A VoIP home phone runs over your internet, so it stops working in a broadband or power cut. That is the one real trade-off against the old copper line. Good providers soften it with offline alerts that warn you and your trusted contacts. Ofcom and consumer groups such as Which? also advise keeping a charged mobile for emergencies. For most homes the outage risk is small, and the better features and scam protection outweigh it.

The bottom line

Every UK home with a landline will move to a broadband phone before the copper network closes in January 2027. So the question is not whether to switch, but which VoIP home phone to switch to. Voipfone suits light users on a budget. BT and TalkTalk suit people who want one bill. But if scam protection, keeping your number, and looking after a vulnerable relative matter most, a safety-first service like Phonely is the strongest all-round choice for 2026.
