Xilo is hard to beat
Xilo (https://www.xilo.net/adsl_broadband/) is fantastic.
Rock solid connection, static IP, and absolutely no download cap...I approached 700 gig one month* with no complaints from them.
*my old NAS went tits up with no backup, so I downloaded all the content again, as I couldn't be arsed re-ripping all my DVDs/Blu-Rays
