The engineer turned up around 12pm and finished the install within 45 minutes. We are currently syncing at 40,000 down and 1,999 up but very, very strangely - our upload throughput is 10mbps this morning! I've tested it on the PC via wired connection, iPad and iPhone on Speedtest.net and all are coming back between 8.5 an 9.5mbps upload

On a side note though, I went with Sky as their 40mbps service wasn't much less than the 43mbps that the BT estimator said we could get, but when the engineer came to install the line he said it was theoretically capable of 88mbps (even though they only do a 76mbps service, can anyone explain this to me?) I was then thinking about leaving sky during the cooling off period as I really don't mind paying more money for a much faster service so I rang sky and asked them about their 80/20 fibre pro, which isn't supposed to be available here yet, but the lady on the phone said that it is actually available now and that after their systems had refreshed overnight I could ring and order it today, which I will do this evening (as I was on hold for the best part of an hour last night). Just thought this info might be useful for other people thinking of going with sky but put off by the 40mbps max speed...
