Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what estimate Department estimate of the total number of households in (a) Ceredigion Preseli constituency, (b) Wales and (c) the UK without access to good mobile signal strength as defined by Ofcom.

Ofcom publishes mobile coverage data in its Connected Nations reports at the premises level, but this does not distinguish between premises type. This means there is no differentiation between households and places of work for example.

Following the launch of the Map Your Mobile tool in June 2025, Ofcom’s threshold for good mobile coverage, combining 4G and 5G, is a predicted received signal strength of −95dBm. Predicted coverage at this threshold is also now included in Ofcom’s Connected Nations report.

Our estimated number of premises without access to good mobile coverage for each area is provided in the table below. Data for total number of premises and the percentage of premises with good mobile coverage is presented as in Ofcom’s Connected Nations Report 2025.
