Can I switch broadband without a landline?

Last reviewed: 22 March 2026

Yes, an increasing number of UK broadband deals no longer require a traditional landline voice service. Full-fibre (FTTP), cable and 4G/5G home broadband all deliver internet without a copper phone line. Even fibre-to-the-cabinet (FTTC) uses a phone line for the last stretch of cable, but you do not have to pay for a voice call package on top. This guide explains which technologies need a line, which do not, and what to consider if you still want a home phone number.

Technology breakdown

FTTC still uses a line – but you may not need voice

FTTC broadband requires a physical copper line between the street cabinet and your home. This means you pay line rental as part of the package cost. However, most providers now bundle the line rental into the broadband price and do not force you to add a separate voice call package. In practice, you have a “line” but you do not have to use it for phone calls.

If your goal is simply to avoid paying for calls you never make, check whether the provider’s FTTC package includes calls by default or lists them as an optional add-on. Many have moved to broadband-only pricing even on FTTC.

VoIP as an alternative to a landline

If you still want a home phone number but do not want a traditional landline, VoIP is the solution. VoIP routes calls over your broadband connection instead of a copper line. Several options exist:

• Provider VoIP – BT, Sky and others now offer VoIP-based home phone as part of full-fibre packages. You plug a normal handset into the router or a VoIP adapter.
• Third-party VoIP – services like Vonage or Sipgate let you get a UK landline number that works through an app or a VoIP handset on any broadband connection.
• Mobile – many households have simply replaced the landline with mobile phones entirely.

If you want to keep your existing landline number, you can usually port it to a VoIP service. See our number porting guide for the process.

What about alarm systems and care lines?

Some older monitored alarm systems and telecare devices (e.g. personal alarms for elderly relatives) rely on the analogue phone network. If your home has one of these, check with the alarm provider before dropping the landline. Many alarm companies now offer upgrades to mobile-connected or IP-connected alarm panels, but this may involve a cost and an engineer visit.

The analogue phone network (PSTN) is being switched off across the UK by 2027. Even if you keep a traditional line for now, you will eventually need to move to a digital alternative. Starting that transition now avoids a last-minute rush.

Practical checks before you switch

• Coverage – check whether FTTP, cable or 5G is available at your postcode. Our technology comparison guide explains each option.
• Existing number – if you want to keep your landline number, confirm porting is supported before cancelling anything.
• Alarm and telecare devices – contact your alarm provider to confirm compatibility.
• Fax machines or legacy devices – anything that relies on the analogue line will need a VoIP adapter or replacement.
• Contract status – check whether you are inside a fixed-term contract and what exit fees apply.

Frequently asked questions

Will I save money by dropping the landline?

If you currently pay for a separate voice call package on top of your broadband, switching to a broadband-only deal or a VoIP alternative could save £5–15 per month. On FTTP, cable or 4G/5G, there is no line rental at all.

Can I keep my old landline number without a landline?

Yes, in most cases. You can port your number to a VoIP service or to a provider’s VoIP-based home phone product. Request the port during the order process and do not cancel your old line before the port completes.

Is 4G/5G home broadband reliable enough to replace a fixed line?

It depends on your location. In areas with strong coverage it can be excellent, but speeds vary with network congestion, distance from the mast, and building materials. It is worth ordering on a rolling contract first to test reliability before committing long-term.

What about calling 999 without a landline?

You can call 999 from any mobile phone, even without a SIM card. VoIP services registered in the UK are also required to support emergency calls, though location information may be less precise than a fixed line.

Do I need a phone line for broadband if I live in a rural area?

In many rural areas, FTTC or ADSL (both requiring a phone line) may be the only fixed-line option. However, 4G/5G home broadband or satellite broadband provide alternatives that do not need a phone line. Check coverage at your address using our glossary for technology explanations.
