This of course differs from area to area. If Cable Modem is available within an area – I generally recommend that. If not, ADSL is the next choice. But you often find areas where neither is available – and so alternatives such as Satellite Internet come into the frame.
Regardless, finding the suppliers of Broadband in that area and then approaching them about available services can be a time consuming process. One site that helps cut down this process is www.broadbandchecker.co.uk
It’s aimed at “click thrus” – sales based off it’s search results, but unlike other sites it allows you to search on Broadband availability without entering a BT Telephone number – useful if you are literally starting from scratch without even a telephone line.
Search results also go beyond the “normal” two technologies of ADSL and Cable Modem – useful for rural areas and those far away from an Exchange.
