Sure seems kind of steep compared to here. The basic BT "Option 1" package is £11.50 per month (about U.S. $22 at current rates).
Doesn't stop BT, the incumbent telco, from dragging their feet with opening up to competition though!
The folks over in the big city (Norwich) have cable services and other competition, but out here in the Norfolk boondocks there
isn't any competition, at least as far as a conventional POTS local loop is concerned.
