I am with Enta via Aquiss. I added the BBC to the ping list to show off tbh.
There is a 30/300GB cap Peak/offpeak for £25 (can get this for £20 from other resellers such as ADSL24, UKFSN, Vivaciti, Falconnet, Titan-ADSL, etc.) Peak is 8am till 10pm for home and 8am till 8pm for office (has higher upload.) You can see the load on the centrals from here:

Customer service is great too if you ever need it.
