The digital switchover

The UK’s copper analogue telephone network is being retired by the end of 2027.  

The change, also referred to as the ‘Copper Switch Off’, ‘Digital Voice’ and the ‘Public Switched Telephone Network (PSTN) Switch Off’, is already underway and most telephone providers are in the process of moving their customers from old analogue landlines over to new upgraded landline services using the internet.  

• Why is it happening? 

  The switch is being made as the existing copper phone network has degraded over time and is no longer viable. The new network will provide a future-proof, more reliable and dependable service that will run through your broadband network. 

• When will happen? 

  The upgrade will be delivered in a phased approach on a telephone exchange–by–exchange basis with the whole network expected to be fully upgraded by the end of 2027. 

• What do I need to do? 

  Your landline phone provider (e.g. BT, Sky, Virgin Media O2, Vodafone) will contact you before the switch to digital services. Keep an eye out for official communications – be careful not to confuse them with marketing materials. 

  For most people, the change will be simple. You’ll still be able to make calls as usual. In some cases, you may need to switch providers if your current one doesn’t offer voice services after the switchover. If that applies to you, your provider will guide you through the next steps. 

  Unless you are a vulnerable customer or a business, you don’t need to do anything until your provider gets in touch. 

• What will happen when my landline is migrated?

  If you already have an internet connection it can be as simple as plugging your phone into your broadband socket rather than the socket on the wall. 

  If you don’t use broadband some providers will offer an interim, dedicated landline service. This interim solution will allow those customers to use their current landline until a digital solution becomes available. 

• What if I rely on telecare or my landline to access emergency services?

  If you rely on your landline for telecare, alarms, or emergency calls, contact your phone provider (e.g. BT, Sky, Virgin Media O2, Vodafone) to make sure you’re supported during the digital switchover. 

  Providers are working with local authorities to identify and assist telecare users. Support may include free engineer visits and battery backups to keep devices working during the transition. 

  If you’re buying a new alarm or telecare device, check that it’s compatible with digital phone lines. And if you have questions or consider yourself vulnerable, reach out to your provider for guidance. 

• What does it mean for my business? 

  Communications providers are advising all business customers to migrate at the earliest opportunity. You need to review your current infrastructure and devices to determine if any rely on legacy networks such as the PSTN or ISDN. There are a range of devices and systems affected that could impact your business including analogue phones, fire and other types of alarms, payment terminals, lifts and elevators, intercom systems and broadband services. 

  You can contact your communication provider for help on how and when your business will be affected. You will then need to make the switch to digital solutions, and this will likely involve upgrading and replacing existing systems and equipment. 

• What else do I need to consider? 
  • Power cuts: Digital landlines won’t work during a power outage. If you don’t have a mobile phone or another way to call emergency services, contact your provider – they’ll offer a solution to keep you connected. 

  • Costs: There shouldn’t be any extra charges for installation or using the new service. Providers will supply any necessary routers or adaptors. You may only pay more if you upgrade your broadband or need a new phone. 

  • Stay safe from scams: Scammers may try to take advantage of the switchover. Always verify who you’re speaking to and take advice directly from your phone provider. If you suspect fraud, contact your bank immediately and report it to Action Fraud at 0300 123 2040 or via their website.
