Revealed: London's worst mobile internet black spots as Sadiq Khan unveils plan to tackle problem

Sadiq Khan has announced a plan to address mobile internet black spots across London, as a new report and interactive map expose significant variations in connectivity performance throughout the capital. The initiative sets out ten actions that London boroughs can take to support better mobile coverage.

The report highlights that mobile performance is not uniform across London, with certain areas experiencing persistent problems that affect residents, businesses, and visitors. The interactive map allows users to see how connectivity varies from one neighbourhood to another, providing a detailed picture of where the worst black spots are located.

The ten actions proposed for boroughs are designed to remove barriers to better connectivity. While the specific measures have not been detailed in full, they are intended to give local authorities a clear framework for supporting improved mobile infrastructure in their areas. The plan reflects growing concern that poor mobile coverage can hinder economic activity, disrupt everyday communication, and leave communities behind in an increasingly digital world.

The announcement comes amid wider efforts to improve digital infrastructure across the UK. Mobile connectivity is seen as essential for business, education, and access to public services, and gaps in coverage can exacerbate inequalities between different parts of a city. By focusing on borough-level action, the plan aims to ensure that local decision-making plays a central role in tackling the problem.

The report and map are expected to serve as tools for both policymakers and the public, offering evidence of where investment and intervention are most needed. The interactive element allows residents to check the performance in their own areas, which could increase pressure on authorities to act.

London's mobile black spots have been a longstanding issue, with some central areas reportedly suffering from weak signals despite their proximity to major commercial and cultural districts. The causes can range from building density and planning restrictions to a lack of suitable sites for mobile infrastructure. The new plan seeks to address these challenges by coordinating efforts between the mayor's office and local councils.

While the full impact of the plan will depend on how quickly boroughs adopt the recommended actions, the publication of the report and map marks a step towards greater transparency about mobile performance. It also provides a baseline against which future improvements can be measured.

The mayor's office has not set a timeline for when the black spots might be eliminated, but the ten actions are intended to accelerate progress. Stakeholders across the telecommunications sector and local government are likely to watch closely as boroughs consider how to implement the guidance.

For now, the interactive map offers a stark illustration of the digital divide within London, showing that even in a global city, reliable mobile connectivity cannot be taken for granted. The success of the plan will hinge on sustained collaboration and investment, but its launch signals that the issue is now firmly on the political agenda.
