G'evening Jenny.........I realise that shortly you will be going into a different arrangement with BT. However, I am unaware of the exact deal you have made with BT.
The deal that I have made with BT was outlined in a previous thread of yours and I am hoping that you have something similar...unlimited broadband usage. Ref:-

Incidentally, I was led to believe that I could expect a download speed of 36 Mbps but I have now been informed in an e/mail from BT......"We estimate your download speed will be between 54Mbps and 55Mbps, and your upload speed will be between 9Mbps and 10Mbps. The minimum guaranteed speed you can expect from your broadband will be 52Mbps".
One does need to keep their eyes on BT and question a lot if necessary.
Hans.
