You can check for mobile and 5g coverage at your address for the four major providers (EE, O2, Vodafone and Three) using the following website www.ofcom.org.uk/mobile-coverage-checker
If your coverage is poor, most providers allow you to operate your mobile phone over your broadband link ‘Wi – Fi Calling’. Mobile Signal Boosters that work by boosting the mobile signal indoors are also available. Further information is available from this website www.ofcom.org.uk/phones-and-broadband/coverage-and-speeds/improving-indoor-coverage
Full fibre broadband and ‘Fibre to the Cabinet’ from Openreach is available throughout most of the village and Virgin Media Full Fibre broadband generally fills in the gaps.
To check availability, use the Openreach checking website www.openreach.com/fibre-checker or, for Virgin Media, use www.virginmedia.com/broadband/broadband-only
Openreach propose that, by the end of January 2027 all telephone services that currently use the copper network will be switched over to operate using Voice Over Internet Protocol (VoIP) technology via digital “fibre” networks. The copper wire network to the street cabinets will be switched off but those without Full Fibre, the copper wires from the street cabinets to the homes will remain live until Full Fibre is available.
https://commscouncil.uk/wp-content/uploads/230331_Consumer_Guidance.docx.pdf gives a comprehensive report on what this will mean for us all. Openreach have an obligation to ensure that every household retains their landlines (if required) using broadband to operate). USwitch offer advice on issues involved in this transition at the following website https://telecomreseller.com/2022/12/05/uswitch-reveals-knowledge-gap-around-the-copper-switch-off-among-pensioners-and-how-it-will-affect-their-generation/.
It is your phone provider's responsibility to migrate you to VoIP as painlessly as possible and give you all the equipment required. If it doesn't, you should complain to Ofcom at www.ofcom.org.uk/make-a-complaint/complain-about-mobile-phone-or-internet-services.
At present, we can find no dates for the proposed switchover, although Openreach have stopped selling new traditional analogue lines across the entire UK network.
