Yes, 1mg with Tesco for a few years at £18pm for broadband only, plus BT line rental and calls at BT standard rates. Bloke next door was getting 6mg with Orange (for some reason his broadband was not secured so I could use it and compare speed tests), which caused me to realise I was being had, and act. I’m now with Orange and getting up to 15mg occasionally, sometimes a bit less, but paying £19pm all in for bb, phone and line rental. I’m now saving lots of money per year (i think I worked it out at £200+pa saving) and getting much faster bb with Orange*.
* other suppliers will do similar ‘all in’ deals I expect and have the appropriate kit installed at your local exchange to give faster speeds.
