The Bromley by Bow Centre’s Connected Lives project will support residents who attend the Centre’s Welcome Hub programmes, like its community food pantry, by providing digital skills training and devices to use for practical life tasks like managing benefits and paying bills online.
Elly De Decker, CEO of Bromley by Bow Centre: "Technology is ever-present in all aspects of our lives. Too many people, for a variety of reasons, are not able to engage with the growing influence of this technology, leading to more exclusion and inequality.
"The reality in our community is that many people do not have the skills and access to the right tools to engage in the digital economy with confidence. We see this every day and we are working alongside local residents to help them improve their skills and confidence in practical and meaningful ways. This funding is absolutely crucial to reducing the digital divide."

Minister for Digital Inclusion, Liz Lloyd said: "This government is tearing down the barriers to success and making the future work for all, not just the fortunate.
"Being online is something many of us take for granted, but for millions it could mean a new job opportunity, quicker access to healthcare or a lifeline to the local community.
"This fund will both empower community organisations to help those most at risk of being left behind get the skills, access and confidence they need - while also informing how we can help even more people in the future."
