This doesn't seem to be the case, and it's often significantly less than the Line Speed.
For example, I've just run a BT Broadband Speed Test (19:30 in the evening):
Download speed achieved during the test was - 4714 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :7616 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 6500 Kbps
The throughput of 4.7 Mb/s is well below the IP Profile of 6.5 Mb/s?
I do occasionally see throughput of over 6 Mb/s, but this is unusual.
Why is this? Is it likely to be a consequence of contention on the BT Wholesale circuit that provides the link to the exchange?
Any thoughts/comments much appreciated.
Thanks

Even then comparing the speed against the IP Profile may not be that useful as a number of other factors come in to play. If you are using a wireless connection it is very likely that your speeds will be lower. You may need to tune your MTU and RWIN settings to get better speeds.
What you should be doing is comparing your speed at different times of the day using the same tester (but not the BT tester). If you are seeing slower times in the evening to say around 9am then there is something to be looked at, but the most likely culprit will not be Plusnet but exchange contention. If you are still on 20CN you can mitigate that by going to Max Premium which as well as a faster upload gives you higher priority on the BT network - but it will cost you an extra £7.83.

The status of my exchange is GREEN.
I don't normally use the BT Speed Test, but wanted to check the IP Profile. Other test tools tend to report slightly higher throughputs, but the results are consistent with the BT tool.
It's 10:30pm now, and I'm still only getting 5 Mb/s.
I'll take your advice and measure again later when there really should be very little contention on the exchange.
Thanks again for taking the time to reply.

The network performance graphs here show the network is busiest (upstream and downstream) from around 5PM until after 11PM and that does impact on speeds - connection management related as well as raw throughput.

Any more idea? Should I get Plusnet support to take a look?

Is this value updated more regularly than the DSL Connection Rate reported on the BT Speed Test, as this reports 7.5 Mb/s?

If you are lucky and one of the care team are on over the week end they can do it manually, other wise you will have to wait til Monday

I've just ran a line check and the speeds are inconsistent. I'm getting onto BT now to see if I can get that sorted.

That should have cleared now. I'm seeing 7150 both sides.
