A new study has used data from 279,186 consumer speedtests to produce a list of the top 20 fastest and slowest UK streets for broadband ISP download speed. Overall Greenmeadows Park (Cheltenham) has been named the slowest on 0.14Mbps, while Abdon Avenue (Birmingham) was the fastest 265.89Mbps.The uSwitch.com research is based on speed tests conducted between 1st October 2017 and 30th September 2018. This took the slowest and fastest postcodes from the 279,186 speeds tests, across 148,013 unique IP addresses within 29,816 postcodes. In order for a street to qualify for inclusion, tests from at least 3 unique IP addresses and at least 10 residential properties were required at a postcode.Overall the study found that 26.3% of the data sample struggled with speeds of less than 10Mbps (starting speed for the Government’s forthcoming Broadband USO), while 13.3% crawl along at less than 5Mbps, but happily the number of broadband users enjoying faster speeds is growing. Nearly a third of users (31%) now get speeds of 30Mbps+ (up from 22% three years ago).Apparently broadband users living in the South West of England (Devon, Dorset, Cornwall and Wiltshire etc.) are also the most likely to find themselves with superfast speeds (i.e. home to some of the UK’s fastest streets).
