Your guide to the PSTN switch off - support if you have a healthcare alarm, disability or additional needs

As the PSTN (Public Switched Telephone Network) gets closer to the switch off date, we’re urging all business and public sector customers to act now to go fully digital and safeguard their services. 
 
We’re urging customers to switch to newer, more reliable networks by the end of 2025. The old, analogue network will be switched off for good by the end of January 2027.

We'll give all customers plenty of notice when we are preparing to switch you to the new service. We recommend you take any action when we contact you so that any devices you have connected to your service aren’t impacted by the switch.

I have a disability or additional needs

If you’re affected by any of the following, we’d like to offer you additional support through the switch to a digital service:

  • Dementia and other cognitive conditions
  • Neurodiverse conditions
  • Speech or language impairments
  • Physical or motor impairments 
  • Any degree of sight loss
  • Hearing loss

How can I register my needs?

You can register through My Account.

You’ll need your user name (which is your email address) and password to log into your account. If you’ve forgotten your log in details you can reset it with either your email address or BT Business account number.

If you haven’t set up an online account yet, simply register for My Account

If you’d like to speak with one of our specialist team, contact us on 0800 121 7445. We’ll take some basic information and update your records so that when you move to an IP solution we can give you the support you need. 

Why should I register my needs?

So that we can give you the right help and support to switch to a digital solution (including how we communicate with you about any changes).  Our support team will be contacting customers who have registered with us to understand how we can support you through the switch over and guide you through the next steps.
 

I have a healthcare alarm, how will the PSTN switch off affect me?

Healthcare alarms include any type of device that you might have connected to your phone line that will keep you safe in an emergency. They can be called different names, so you might know them as:
  • Telecare / healthcare alarms
  • Personal care alarms
  • Medical help buttons
  • Emergency response alarms
  • Corded or wearable fall detection devices, such as bracelets or pendants
If you have any of these types of devices connected to your PSTN lines, then they might not work on the digital network. You will need to contact your device provider, who will be able to tell you whether your equipment will work or if there’s anything you need to do before switching, to ensure your device will continue to work on the digital network.

Frequently asked questions:

Will my digital service work in a power cut?

If there’s a power cut or your broadband fails, you’ll be unable to make any calls on the digital network, including 999 calls. You’ll still be able to use a mobile phone, just make sure you keep it charged at all times. If you don’t have a mobile phone or are in an area with no mobile signal, please contact us on 0800 028 2075 and we’ll discuss your options with you.

Your device provider will be able to tell you whether your healthcare alarm uses a mobile sim. If it does, as long as you have a mobile signal, your alarm will still work in a power cut. If your healthcare alarm won’t work in a power cut, then let us know and we’ll provide you with a resilient solution.

Fraudsters are known to call claiming to be from BT, when it’s actually a scam.
