Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what assessment her Department has made of the adequacy of Ofcom’s mobile coverage maps.

The Government recognises the concerns from members across the House that in some cases, the level of mobile coverage reported by Ofcom does not align with users’ experience. Improving the accuracy of coverage data and improving the information available to consumers on the performance of mobile networks in their area remains a priority for the Government.

Government has restated the importance of Ofcom continuing to improve its reporting of mobile coverage in the draft Statement of Strategic Priorities for telecommunications, the management of spectrum and postal services. This includes building on the launch of Map Your Mobile tool in June 2025, by exploring more use of measured and crowdsourced data. It also includes Ofcom keeping under review its definitions of what constitutes “good” 4G and 5G and the signal strength thresholds it uses to measure this, so that these definitions continue to reflect consumer and business expectations as user requirements and behaviours evolve.

Ofcom introduced the feedback function in the Map Your Mobile tool to ensure that consumers who are dissatisfied with the results have a way to register concerns or observations about mobile coverage in their area.

It provides Ofcom with a qualitative source of consumer experience to complement existing data and monitor broad trends over time, such as recurring locations where issues are raised. This remains under review as the dataset grows, Ofcom continue to assess how it can most effectively support their work.
