Analogue phone line switch off: What do you need to know?

In 2025, the UK will hang up on analogue phones for good and switch to fully cloud-based solutions.
This impacts everyone, and analogue phones aren’t the only consideration. It affects everything connected to your old phone networks, such as door entry systems, lifts, CCTV, etc.
This is an incredible business opportunity, but without careful preparation, 2025 could be a year of chaos, disruption, and unprecedented costs. Is your organisation ready for the deadline? In this article, we’ll tell you everything you need to know about the upcoming changes and how Nviron can help you prepare.
How will businesses stay connected when analogue phone lines are switched off?
VoIP technology – delivered by fibre optic cables – will replace the existing infrastructure. VoIP stands for Voice over Internet Protocol, which allows users to make voice calls using an internet connection.
Rather than passing the signal through copper wires like the old system, a VoIP landline phone plugs into your internet router and uses your WiFi connection to make and receive voice calls wirelessly.
The rollout of VoIP closely follows the UK Full Fibre internet expansion.
Once there is a 75% penetration of FTTP in your area, what’s known as a “stop sell” comes into place on old technology. Once Ultrafast broadband is an option for your business, you can no longer buy an ISDN or PTSN connection. Instead, the more reliable and higher quality VoIP connection will cover your landline.
Now that most of the UK has access to a reliable internet connection and the rollout of full-fibre technology is gathering pace, digital transformation at scale is achievable. As a result, a host of cloud communications products and services are becoming available – providing far superior service to the copper phone lines of the past.
The benefits of VoIP technology include:
- Better functionality – VoIP technology can do much more than voice calls. Depending on the system you want, you can choose other features, such as video calls and instant messaging.
- Mobile friendly – Cloud-based VoIP systems allow users to connect wherever they use a mobile phone or tablet. This is ideal for many types of businesses as it will enable users to make and receive work calls without physically being in the office.
- Cost-saving – Many VoIP packages offer cheaper deals and cheaper calls. This can include free international calls or calls between multiple offices, depending on your need.
- Portability – VoIP numbers are entirely portable, so you can use the same number wherever you go. This is ideal for those who travel a lot. Businesses which change their address can still retain the same number.
- Higher quality sound – As long as you have a good internet connection, call quality is crisp and clear with minimal lag.
How can businesses prepare for the 2025 Switch Off?
Businesses of all shapes and sizes must prepare for the Great British Switch-Off. Below, we have outlined some top tips to help you get ready:
- Check your connection – Do you have a good internet connection? If you don’t, now is the ideal time to upgrade in preparation.
- Look at your contract – Now is the time to check your internet contract, as that will give you an idea of how soon you can make the switch. Switching as quickly as possible will save you effort and money in the long run.
- See what else is using your lines – If you run a business, your phone lines are likely being used for more than just voice calls. They can be used for anything from door entry systems to cash machines and alarms. Upgrading will impact how these services function – so be sure to track them down so you can make preparations.
- Don’t buy old tech – This is especially important for new businesses. Buying outdated hardware, such as desk phones, is not advisable, as you’ll just be wasting your hard-earned money in the long run.
- Educate other users – Whether you run a business or live in a busy household, multiple people will likely use your phone line. Make sure everyone knows how to use the new technology.
