TBB 50/10 Speedtest FTTP
I know you may not beleive the 50/10 FTTP but I have linked a speedtest, my neighbour is on the same package as us and I have looked up online to see if others have 50/10 and yes it is a thing.
BT Launch 55/10
Granted bt list it as 55/10 but we have never got faster than 51 and on the BT site under fibre it is listed as 50Mbps fibre 1 TBB article BT Fibre 1
Do some research if you don't believe people
The confusion arises from the difference between the technical aspects/specification of the Openreach 55/10 product you are on and correctly paying for, and the speeds ISPs are allowed to advertise on their websites and in the media. The ASA requires adverts to state nothing above what at least 10% of users of the product can actually receive.
In the case of BT Wholesale-based providers on FTTP this will generally be just below the limit imposed (for technical reasons) by the IP Profile. Almost all users of that product will get speed test result like yours, unlike distance variations on the equivalent FTTC 55/10.
If you check your line stats in (probably) the Troubleshooting section of your Hub GUI, you should see 55,000Kbps. Maybe 1 or 2 lower.

To argue with mindless bigots is foolish.
