When will landlines be phased out in the UK?

The end of the line for landlines is fast approaching, so how ready is your business for the change? We have recently updated this page to inform you of the upcoming  2025 switch-off. Read more about the impact this may have and how we can help minimise any frustration. 

Contents

Landline phone systems will be switched off from October 2025. Going forward your only option will be to use broadband to make calls.

If you are currently relying on a landline, you will still be able to make calls but the technology that powers them will be different. Find out everything you need to know and pick the best options going forward.

What is happening to landlines in October 2025?

Traditional landlines will be switched off in 2025 and replaced with a digital network. This means Public Switched Telephone Network (PSTN), which uses copper cables to bring the connection to your home and business, will no longer be available. We are here to help with the transition from landlines to digital phones!

Why is the switch-off happening?

The old PSTN and ISBN lines just can’t meet consumer expectations and are becoming more difficult to maintain and repair.

This will affect:

  • Phone lines
  • Lift phones
  • Alarms
  • Door entry systems
  • Fax machines
Check your business thoroughly for any outdated technology.

What tech is replacing landlines?

Voice over Internet Protocol (VoIP) is already a popular choice for many businesses. We will be able to communicate via voice calls, video calls, and messaging anywhere where there’s an internet connection.

What do businesses need to do?

If you are still using a PSTN or ISDN connection, you need to think about a good time to switch over to a VoIP system with minimal disruption.

Give yourself enough time to plan, especially for the time where your old telecoms service will not be available, as well as to prepare for any costs that may be involved.

You may be able to use some of your existing telecoms equipment but you will still need to replace hardware such as phones, faxes, or security alarms.

Can I keep my number after the PSTN switch off?

You will still be allowed to keep your existing business or personal phone number.  In addition to this, you might also want to consider how digital telecoms can put you at an advantage. 

Why is switching to digital telecoms a good thing?

Use the following to educate yourself on the benefits of a more modern telecoms system:

Are you ready yet for the digital telephone switchover?

  • Many businesses have already made the transition to digital technology or have started the move.

    You will need additional security considerations because anything connected to the internet is at risk of cyber-attack if you aren’t employing the right security defences.

Why choose Syn-Star to help with the transition?

  • We are a BT wholesaler that has been providing support for businesses for the last 20 years.
