ADSL coverage is available to around 80% of the UK population. As such, it is the most likely choice unless you happen to live somewhere remote, or in an area where cable is available.
ADSL broadband is delivered through your existing BT telephone line, using a special modem or router. There is no need to have an additional telephone line installed and you will be still be able to make and receive calls whilst surfing the web.
When you have an ADSL connection it is necessary to fit small devices called microfilters to all your telephone sockets. You need to plug them in to prevent the ADSL signal from interfering with your voice calls. Typically your ISP will provide you one or two microfilters and, if you need any more they only cost a few pounds.
Although you must have a BT telephone line, there are many ADSL Internet providers to choose from, each offering a selection of different deals.
