Each month hundreds of thousands of broadband customers test their speeds with our broadband speed test. Since the end of 2015 there's been little change in average speeds from home broadband with average download speeds for March 2016 coming in at 20.41Mb and average upload speeds at 3.73Mb.
However, our test also supports users testing on tablets and smartphones, meaning we can report on mobile broadband speeds from 4G and 3G networks. While home broadband has been stable, mobile broadband average download speed has risen by a full 2Mb since December and upload speed by 1.6Mb, the average mobile broadband speeds for March 2016 were 15.31Mb download and 3.71Mb upload.
When the big mobile broadband and home broadband providers' average speeds compete on the same table, it's only Virgin Media's DOCSIS 3 cable broadband that outperforms mobile broadband, clocking in 46.95Mb, with upload speeds at 5.9Mb. 4GEE is ahead of BT Broadband with download speeds clocking in at 18.71Mb, faster than BT by 1.07Mb. 4GEE and Vodafone mobile broadband sit in overall 2nd and 4th places beating all home big broadband providers' averages bar Virgin Media, with Vodafone's 16.26Mb average mobile download speed only 1.38Mb behind BT.
Of the home broadband providers Post Office Broadband still has the UK's slowest broadband speed overall with only 4.38Mb average downloads and 1.67Mb average uploads, well below the average speeds expected for copper phoneline broadband. Three tested with the slowest mobile broadband at 12.09Mb downloads, but this still beat home broadband offerings from Sky and EE.
When the supplementary broadband providers table (see page 4 of the report) is included we can see that fibre to the building provider Hyperoptic tested as the fastest broadband overall with 91.7Mb average downloads and 77.3Mb uploads.
