You have to remember that more and more people are getting online now and bandwidth costs money. ISP's also love oversubscribing and not putting money back in to upgrading their network.
Take Virgin Media. Pre VM, Telewest was awarded consumer broadband choice year after year. When VM took over they introduced Traffic Management for broadband connection.
Basically between 4pm and midnight all broadband customers are subject to Traffic Shaping if they go over a certain quota. on the 20mb tier the allocated amount is 3gb. Once over this limit your connection is Traffic Managed, reducing its speed to 6mb and 192kb upload.
I don't think VM are the only ISP to be Traffic Managing connections during Peak times. It could also be one of the reason your connection is slow.
