What assessment it has made of the impact of the planned switch-off of the Public Switched Telephone Network on rural and island communitie…

As you will already be aware, responsibility for the UK’s telecommunications network is reserved to the UK Government, with the Department for Science, Innovation and Technology being the lead government department.The move to digital-based services is an industry-led decision and process. The decision to upgrade the legacy PSTN network is driven by the increasing fragility of the 40-year old analogue landline technology and the increased difficulty in maintaining the current network, due to reduced availability of replacement parts and the reduction of expertise in these analogue systems.Universal Service ObligationsIt is worth noting that the PSTN migration does not affect the Universal Service Obligations set in the Electronic Communications (Universal Service) Order 2003, which require the designated providers to offer telephony services throughout the UK, and providers will remain bound by their existing statutory responsibilities.Ofcom, the independent telecoms regulator, has issued guidance on how telecoms companies can fulfil their regulatory obligation to ensure that their VoIP customers have access to the emergency services in such circumstances. This guidance states that providers should have at least one solution available that enables access to emergency organisations for a minimum of one hour in the event of a power outage in the premises. The solution should be suitable for customers’ needs and should be offered free of charge to those who are at risk as they are dependent on their landline.You can read Ofcom’s full guidance at the following links:Guidance: Protecting access to emergency organisations when there is a power cut at the customer’s premises

- OfcomCustomers who are not eligible for a free resilience solution should be able to request one but their provider may charge for it. Customers who are moving to VoIP services and are reliant on their landline should discuss their situation and requirements for a back-up solution with their provider before they are moved on to VoIP services.Shared Rural NetworkUK-wide initiatives will also bring coverage improvements in Scotland. The Shared Rural Network (SRN), led by the UK Government’s Department for Science, Innovation and Technology (DSIT) and the UK’s main network operators (O2, EE, Vodafone and Three) will make significant investments in 4G coverage: up to £1Bn to increase 4G access on at least one network to 95% of the UK’s landmass (which equates to around 91% of Scotland’s geography). This is a substantial increase on coverage levels of around 44% when the programme commenced in 2020. Ofcom’s most recent Connected Nations 2025 report states that as of July 2025, 90% of Scotland’s landmass had access to at least one mobile operator.SRN is structured around two distinct but complimentary projects: the operators worked collaboratively to improve partial not-spots- those areas where 4G is only available on one or two providers – collectively investing in excess of £500 million on a commercial basis. This Partial Not-Spot project completed last summer.Building on this, the UK Government is funding a second phase which is currently working to address 'total not-spots', areas where there is no coverage from any network provider and no likelihood of commercial investment. Further information about SRN is available at Shared Rural Network, including a high level map showing which areas will benefit from new Total Not Spot masts. Initial locations for Total Not Spot masts met strong opposition from groups such as the National Trust for Scotland, Scottish Land and Estates, the John Muir Trust and others over concerns for the impact on sensitive ‘wilderness’ landscapes and biodiversity. We brokered discussion among the mobile industry, UK Government and representatives from these groups to identify a
