He's on Unlimited John, not pro/payg - however the throughput is still rubbish for the current profile.
Rob, the good news is that your BT IP profile is the max you can get. That's the first BT profile I've seen rise as quick as that in a while on these boards!
Can you login to

All we have to do is sort the wiring issue which is responsible for the slower sync speeds and probably responsible for most of your line drops when connected normally.
A brief explanation - it's called the bell wire issue - the orange wire on 3 specifically - it provides the ring signal on a conventional POTS circuit, but is not required or desired in a broadband situation. It's connected by a capacitor to the line on terminal 2 at the master. This un-balances the pair of wires (at ADSL frequencies) that provide your connection. It also acts as a big aerial picking up interference and this lowers your noise margin which results in slower sync speeds.
The solution is easy - all you need to do is gently remove the orange wires from terminals 3 & 4 at the master and at each extension socket.
The connections are IDC (Insulation Displacement Connector) terminals - just gently pull the wires vertically out of the connector - being careful not to disturb those on 2 & 5. Then just coil them back out of the way where they won't touch any other terminals.
A bit more to follow about that bad throughput, but posting this so you can read it.
