Superfast South Yorkshire (SFSY) is a partnership between the local authorities of Barnsley, Doncaster, Rotherham, Sheffield, and the South Yorkshire Mayoral Combined Authority. It was established in 2014 to improve the digital infrastructure throughout South Yorkshire as superfast broadband was rolled out, and has subsequently continued to drive strategy across the South Yorkshire region as technology has advanced, working first on the roll-out of 4G mobile data and now on the roll-out of 5G.

The first phase of the superfast broadband roll-out was delivered in partnership with Openreach, part of the BT group, and was completed in September 2019. This first phase saw almost £27m funding invested to reach an additional 95,000 premises that would otherwise not have been reached, since their locations made them less commercially viable for broadband providers. The second phase is currently in delivery and has brought gigabit capable broadband on the Openreach network to an additional 6,000 premises. Over 100,000 residents and businesses have directly benefited from the Superfast South Yorkshire programme. 

Since 2022 Superfast South Yorkshire has been partnering with South Yorkshire Mayoral Combined Authority to deliver the combined authority's Digital Infrastructure Strategy. This is one of three key areas of activity that have been identified as being critical to addressing the digital agenda across South Yorkshire in an integrated way. The other areas are digital skills, and digital innovation and business support. These three strategies together will form a holistic approach to driving digital innovation and inclusivity to deliver the digital ambitions of the combined authority.

South Yorkshire Digital Infrastructure Strategy

The South Yorkshire Digital Infrastructure Strategy is a document approved by the Combined Mayoral Authority in September 2021, which sets out how we intend to accelerate the development of gigabit capable digital infrastructure and 5G networks across the whole of South Yorkshire and includes proposals for public interventions to support achieving this strategic ambition. It sets out a vision for South Yorkshire to "be recognised as one of the best-connected city regions in the country where coverage, choice, and speed of communication stays ahead of demand" where "a Gigabit infrastructure... accelerates new social and economic possibilities for all the people and businesses of South Yorkshire."


"Almost 99% of homes and businesses across South Yorkshire are now able to access superfast broadband, with the average download speed for the region in the last 3 months of 2023 at 116Mbps, according to independent reporting from ThinkBroadband ." 

This has been achieved through a mix of commercial delivery by broadband providers and delivery driven by Superfast South Yorkshire. Superfast broadband provides the necessary speeds to allow multiple devices to be connected and working without slowing each other down, for example multiple people working from home, video calling, gaming, streaming etc.

Superfast South Yorkshire are now working with the Government and commercial suppliers to support the delivery of gigabit-capable infrastructure across the region, including Project Gigabit.

 Mobile data (5G)

What is 5G?

5G is the newest generation of mobile networks following on from 3G and 4G, offering faster and more reliable connections along with increased capacity, meaning more devices can be connected in an area at the same time, accessing faster, more reliable mobile data.

This technology is future ready and will enable the smart towns and cities of the future, transforming the way we communicate, manufacture and travel, to list a just few of the areas of potential anticipated from this technology. 

The remit of the Superfast South Yorkshire team has been expanded over time to include working on mobile data infrastructure projects and supporting the mobile networks in rolling out 5G.

New Property developments

Since 2019, Superfast South Yorkshire are consultees for Barnsley, Doncaster, Rotherham, and Sheffield local authorities' Development Management Services.  This means that SFSY are consulted on planning applications for new residential and commercial development, and on enquiries relating to deployment of appropriate broadband infrastructure on new developments. This is to ensure that all new developments across the region are built with digital infrastructure set for the future. 

For both residential and commercial developments, the earlier the developer engages with digital infrastructure providers the easier and more cost effective it is to install the infrastructure to sites. Developers will be asked to consider installing gigabit-capable full fibre infrastructure from multiple network operators to provide choice and competition to consumers. Occupiers should be able to access broadband ideally from a choice of at least two network operators upon occupation of the premises. 

Developers should also consider their ability to upgrade the infrastructure in the future to minimise disruption to occupiers/users.
