December 2015 saw average download speeds for fixed line providers recorded by users of our broadband speed test remain stable in comparison to the results from November, coming in at 20.56Mb. Average upload speeds saw a 0.15Mb drop to 3.68Mb.
Of the big 5 home broadband providers, Virgin Media remained in first place but their average download speeds appear to have levelled out since rolling out their 200Mb service, remaining stable at 46.57Mb, with upload speeds at 5.66Mb. BT Broadband retain second place with average download and upload speeds steady at 17.58Mb and 4.42Mb respectively. TalkTalk move up to third place, with download speeds stable at 12.8Mb and upload speeds dropping by 0.21Mb to 1.86Mb. Plusnet drop into fourth place, dropping by 0.59Mb to 12.6Mb for average download speeds with a 0.39Mb decrease to 2.85Mb for average upload speeds. Finally, Sky remain in fifth place with a 1.1Mb fall in download speeds to 10.92Mb, while their upload speeds decreased by 0.41Mb to 2.47Mb.
Results from users testing with mobile-enabled devices including phones and tablets suggests that mobile broadband speeds saw an overall rise since November. Taking mobile broadband separately from home broadband, EE Mobile retain first place, with download speeds increasing by 1.1Mb to 17.55Mb and upload speeds holding at 3.87Mb. Vodafone are in second place, seeing download speeds fall slightly by 0.19Mb to 13.76Mb and upload speeds steady at 2.82Mb. O2 are in third place with download speeds at 11.78Mb - a respectable 1.4Mb increase over last month - and upload speeds at 2.53Mb. Three are still in fourth place, with average download speeds of 9.84Mb and upload speeds of 2.56Mb.
When mobile broadband and home broadband average speeds compete on the same table, 4GEE is head-to-head with BT's second place with a difference of only 0.03Mb. 4GEE and Vodafone mobile broadband sit in overall 3rd and 4th places beating all home broadband providers' averages bar Virgin Media and BT. This suggests that 4G broadband may have higher uptake levels relative to 3G compared to uptake of the fastest possible fibre broadband products relative to cheaper options.
This month's supplementary broadband providers table (see page 4 of the report) found Post Office Broadband had the UK's slowest broadband speed overall with only 2.55Mb average downloads and only 0.33Mb average uploads. Hyperoptic was fastest overall with 102.1Mb average downloads and 92.13Mb uploads.
