Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, how many mobile masts have been installed in (a) England (b) Wales (c) Scotland and (d) Northern Ireland that provide coverage in areas that did not previously have coverage in each of the past 10 years.

Over the last 10 years, Ofcom reports that 4G coverage from at least one operator has risen from 72% in 2016 to 96% in 2025. During this period mobile masts have been installed to provide new coverage via both Government subsidised rollout and by commercial rollout.

For example, through the Shared Rural Network, a joint deal between Government and the network operators, so far a total of 121 masts have been installed or upgraded. As part of this, the Extended Area Services project has provided new commercial 4G coverage across 30 sites in England, 40 sites in Scotland and 49 sites in Wales. The Total Not Spots project has so far installed 2 masts in Scotland.

Government does not track the number of masts providing new coverage via commercial rollout so cannot provide a total figure for the number of new masts that have been installed. It is for network operators to determine if additional masts are needed, and where these should be deployed, to deliver a reliable, high-quality service for their customers. Detail on the availability of fixed and mobile networks in each nation is available in Ofcom’s Connected Nations Report 2025.
