FastNet vs BT: Speed Comparison

FastNet Broadband is the 25th most tested broadband provider in the UK, while BT is the UK's second most tested ISP with 7,092,404 tests performed this year, compared to FastNet's 6,570 speed tests. While looking at the fastest speeds seen from each broadband provider often doesn't tell the full story — BT is first with 6,068.11 Mbps, FastNet 17th with 931.93 Mbps — looking at download speed ranges alongside the percentage of speed tests higher than 50 Mbps will give a clearer picture. In this case, BT has a better broadband speed range than FastNet, ranking 49th nationally, compared to FastNet coming in at 66th place. 17% of FastNet's internet speed test results were higher than 50 Mbps, compared to 35% of BT's.

FastNet vs BT: Performance Ranges Overview

We class broadband speed distributions as follows: very slow under 10 Mbps; slow 10-30 Mbps; adequate 30-60 Mbps; good 60-80 Mbps; fast 80-300 Mbps; very fast over 300 Mbps.


Looking at broadband performance, 81% of FastNet's internet speed tests were slow or very slow. This is worse than BT, who had only 50% of their broadband speed tests classied "slow" or worse. For the average user needing only adquate or "good" internet service, 42% of BT's download speeds fell between 30 and 80 Mbps. This is 3.0 times higher than the 14% of FastNet's speed test results in the same range. At the speedier end of the scale, only 5% of FastNet's broadband speed test results were faster than 80 Mbps, compared to 8% of BT's.
