You can use broadband comparison sites to find the best deal for your broadband needs, sometimes this involves switching providers, if you are already signed up to a broadband provider you can change your service by migrating, transferring your service or upgrading.
If you are migrating from a cable broadband to an ADSL broadband you will need an active BT line, a new modem which is compatible with an ADSL connection. You cannot use your cable modem and additional equipment may be required, like a micro filter, USB connection or Ethernet connection. Installing an ADSL service can take on average 10 days, once ordered your start up package will be sent directly to your home and the connection will be directly activated by the provider.
You can also migrate from ADSL provider to another your BT phone line will not be affected and, you will keep the same phone number as with switching phone providers. All you need is a standard BT ADSL connection and your individual MAC code, which will be supplied from your current provider when you cancel.
Switching to a new provider could give you a cheaper subscription, more speed and better services for your broadband needs
