Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government what percentage of mobile mast sites will be affected by the renewals provisions in sections 61 to 64 of the Product Security and Telecommunications Infrastructure Act 2022; and what methodology they have used for coming to that assessment.

We estimate that the Renewals Provisions will affect approximately 12-18% of UK mobile mast sites. This reflects the number of live agreements that could be affected by the Renewals Provisions, drawn from confidential data provided by industry and internal estimates, as a proportion of the estimated total number of mobile sites in the UK. Given the commercially sensitive nature of the data, further detail is not possible.

The Renewals Provisions extend the changes to the statutory valuation framework introduced by the 2017 Electronic Communications Code to certain cases regulated by the Landlord and Tenant Act 1954 and the Business Tenancies (Northern Ireland) Order 1996 upon their renewal.

Based on reporting by Ofcom in its Connected Nations reports, 4G geographic coverage from all four operators has risen from 40% in 2016 to 84% in 2026 and 5G premises (outdoor) coverage has reached 64% from all four operators in 2026.
