What?? Knowing how much capacity your network has and how much of it is in use is one of the most basic aspects of running any provider network...

You can get some inkling of this from the last published OfCom "average" results for UK VMTiers:
=====================
Broadband speed----Average speed at peak times----Average speed over 24hrs
--------------------------- (8pm-10pm)
Up to 50Mb ----------------- 48.91Mb --------------- 52.37Mb

Up to 100Mb ---------------- 87.48Mb --------------- 99.48Mb

Up to 152Mb --------------- 113.39Mb -------------- 138.7Mb

.... peak download speed data comes from Ofcom’s review of UK broadband speeds published in November 2014, based on Ofcom May 2014 test results.
======================
And herein lies the problem. 24-hour averages are skewed by the 16 hours a day most people aren't even able to use their connection, so for the majority of people aren't particularly relevant. Peak time speeds on the other hand, show clearly there's widespread congestion across the country.

Don't forget 'averages' doesn't mean that's 'average' speed you're going to get, it means 50% of customers get less than that speed*. On a service provisioned at over 160Mbps, most customers get less than 114Mbps at peak times - a drop of nearly 50Mbps. Even across the day most customers can't get above 140Mbps.

* Strictly speaking, that applies only to median averages, while mean averages can be skewed by extreme outliers
