Making a profit from wiretapping

Some interesting news from across the pond here. It seems that Comcast, one of America's largest telecommunications company has a handbook which outlines its charge rate to the Federal Government when requests for writetapping comes in under the Foreign Intelligence Surveillance Act.

Apparently Comcast charges $1000 for the initial wiretap and then a monthly charge of $750 to maintain it. Not a bad little profit. This got me wondering, do BT and the other Telco's charge the Government in the UK for wiretaps? Time to FoI the Home Office and ask, although I don't hold out hope of a reply.
