Transit Providers in Bracknell, UK

[Gary T. Giesen via NANOG <nanog () nanog org>]

Can anyone recommend a transit provider in Bracknell, UK? Not too picky on requirements, but IPv6 is a must;  RTBH and 
good peering are a very good to have.

We're looking to replace one of our current providers (Virgin Media - AS5089). I have no problem naming them as they 
treat prefix list updates like service changes (and charge £250 for the privilege). We gave in and paid it and and 2 
weeks later they have still not processed the change.

Cheers,
