GLA has launched its Connected London Map, which provides an overview of digital connectivity in London.

The map is part of work the Mayor’s Connected London team was set up to do in 2017, to enable a step change in London’s approach to boosting fibre provision and tackle areas of poor connectivity.

The map uses Ofcom Connected Nations postcode data to display coverage by borough, ward and postcode, with the ability to export data.

It looks at the availability of full fibre, ultrafast, and superfast connectivity, and also shows areas of unavailability, where properties can’t access speeds of two, five, 10 and 30 megabits per second.

The map will be updated whenever new data is published, with the next phase including the ability to compare historical coverage. GLA claims the map is the most comprehensive information publicly available.

With this tool GLA hopes to provide councils with a clearer picture on what digital provision looks like in their area to inform their digital strategies and encourage investment in under-served areas.

The map has been well received so far, with Andy Pyle, head of UK real estate for KPMG, sharing it on Twitter.

Sanjaya Ranasinghe, technical director of broadband rating service WiredScore said: “It is great to see local authorities proactively enabling consumers to better understand the capability of internet service available in their area. The GLA’s Connected London map is a springboard to integrate future digital connectivity metrics such as mobile coverage and the range of internet service providers available in a given area.”

Findings from the map

  • Superfast coverage in London is currently at 95.6% of properties, the Department for Digital Culture Media & Sport, DCMS, has a target of reaching 97% by 2020 – GLA thinks this is unlikely to be met
  • Full fibre coverage is sitting around 11.5%, and being contained within small pockets of the city
  • In a blog about the launch of the map, GLA criticised the Government and Ofcom on how data is collected. The dataset is based on self-reported coverage information rather than infrastructure locations
  • GLA said the current system incentivises providers to over-report availability, because Connected Nations reports are only published annually, with two extra updates per year
  • GLA has seen areas being reported as having full fibre coverage where it is not yet available and has suggested Ofcom to publish data more regularly to limit over-reporting
