I sympathise, but I seriously recommend looking at the UK government's attitude towards encryption and privacy before you jump here. They mean well, but… well, the support material for the IP act reads like their understanding of the internet hasn't changed since 1998.
Part of the Investigation Powers Act is that particular ISPs will be required to store an unspecified dataset related to your browsing history for 12 months, and that they have to keep secret the fact that they are doing so.
