Warning Issued as Heatwave Intensifies
UK households are being urged to check their relatives' landline phones before the end of the current heatwave, which is expected to persist through most of this week. The Met Office has issued a 36-hour red weather warning for 50 areas, with temperatures exceeding 30°C across the country until Saturday.
In London, temperatures are forecast to reach 36°C on Wednesday, 34°C on Thursday, 37°C on Friday, and 32°C on Saturday, before dropping to 26°C on Sunday. In Leeds, temperatures will hit 31°C on Wednesday, rising to 33°C by Friday, then falling to 29°C on Saturday and 23°C on Sunday.
Digital Landline Transition Raises Concerns
Experts warn that extreme weather can increase the risk of infrastructure disruption, making it vital for vulnerable people to understand how their phone service would operate during a power outage. This comes as millions of households transition from traditional landlines to internet-based digital voice services as part of the UK's nationwide telephone network upgrade.
Unlike traditional landlines, which were powered through the telephone network, digital phone services rely on broadband equipment and electricity within the home. If power is lost, phone services may be disrupted unless alternative arrangements have been made.
More than 3 million UK households have already been switched to digital landline services, with the nationwide transition due to be completed by January 2027. The issue is particularly concerning for older adults, people living alone, and vulnerable residents who rely on their home phone to contact family, carers, or emergency services.
Vulnerable People at Risk
Recent government figures suggest around 2 million vulnerable people across the UK rely on telecare alarms and related services that have historically used traditional landline connections. Bryn Thompson, Director at digital voice provider Phonely, said: "Many people still assume their home phone will continue working during a power cut because that’s how landlines operated for generations. But millions of households have already been switched to digital phone services, and many families don’t realise there can be important differences during an outage."
He added: "The current heatwave and Met Office warnings should act as a reminder for families to check how elderly relatives would stay connected if the power goes out. For older people who depend on a landline as their primary way of staying in touch, a prolonged power cut could become a serious concern if they haven’t prepared in advance."
Simple Steps to Stay Connected
The UK's analogue Public Switched Telephone Network (PSTN) is being retired and replaced with modern digital technology, meaning millions of households will move to digital voice services over the coming months. While communications providers have introduced protections for vulnerable users, consumer awareness of the change remains low.
Mr Thompson added: "Most households won’t experience any problems, but families should take a few minutes to understand how elderly relatives would stay connected during an emergency. Many people don’t realise there are simple steps that can reduce the risk of being cut off during a power outage, whether that’s having a battery backup, keeping a mobile phone charged, or understanding what support is available from their provider. For many older people, a home phone is far more than a convenience. It’s often their main connection to family, carers and emergency support. A simple conversation now could make all the difference if there’s an unexpected power outage in the future."
